Why the smartphone does not see the memory card and what to do about it

The smartphone stopped seeing the familiar memory card or does not want to work with a new one? It gives errors like "SD card does not work", "SD card is not supported"? Most often, the problem is solved independently and quickly. That's what to do if the smartphone does not see the memory card.

Incorrect installation

If you install a new memory card, make sure it entered the spring-loaded slot to the end. There should be a light click, and the SD card must be completely "recessed" inside.

Having installed the drive in this way, you should not hope that the smartphone will see the memory card.

If the tray is removable, set the memory card according to the miniature scheme specified on the tray itself. It will not work to miss - the card will occupy as a screenshot below, it will simply do not get up differently. After that, the smartphone should immediately see the drive. If this did not happen, reboot the device.

Correct placement of the SD card in the tray

Software failure

In very rare cases, the smartphone can be bugged and not to see the SD card when connected, or in the process of using the error that the card is disabled. The recipe from this disease is the same: pull out the drive, reconnect it, reboot the gadget.

Sometimes it helps to update the firmware of the device.

Go to the smartphone settings in the system. Select "Wireless update". Update the device to the current version.

The file system is not supported.

If the memory card used to be used in a bundle with a PC or smartphone from another OS, then the device may not recognize the drive. To get rid of the problem, format the SD card to the desired format.

  1. In the smartphone, go to "Settings".
  2. Select "Storage and USB drives".
  3. Open microSD, and then call the option, click "Settings" and select "Format".

Remember: Formatting is destroying all the data from the drive, so copy them in advance to the PC or the cloud.

If the first method did not work, the drive can be formatted from the RECOVERY menu. On different models, this mode is turned on differently, but most often needed:

  • Turn off your smartphone.
  • At the same time, press the power button + the volume button down (in some models, the volume must be pressed up).
  • After 10 seconds, the Recovery menu should appear, where the Wipe Cache Partition item should be selected, and then "Yes" to confirm formatting.

If formatting from a smartphone for some reason is not possible, then "reset" the memory card using a computer. For this:

  1. Using the card reader, connect the drive to the computer.

  2. Find the displayed drive, call the context menu by pressing the right mouse button. Click "Format".

  3. For accumulators up to 32 GB, select FAT32 for more capacious - EXFAT.

You can also format the drive by third-party programs, such as SD Card Formatter, which are just for this and are intended.

No permissions

In the latest versions of Android OS, many applications require additional rights, including and to use the device's memory. If you do not give rights, then, for example, the camera application will not see the SD card, although, in general, the drive in the smartphone settings will be displayed. To correct the problem:

  • Go to the smartphone settings to the "Applications" section.
  • Select the application you need, such as "camera" and provide him with all the necessary rights.

Map is incompatible with smartphone

Most SD cards are compatible with any devices, including smartphones, tablets, etc. But in very rare cases, you can encounter a memory card incompatibility and a particular mobile device. Most often, this is happening with high capacity drives, for example, 256 GB.

Low-end smartphones may have limitations on handling such large SD cards. To rule out the problem, check the specifications of your smartphone in advance and make sure that it supports drives of this size.

Contacts oxidized

If the drive has been stored in a humid environment, or your smartphone has been exposed to rain, the contacts on the memory card could oxidize.

To cope with the problem, just take out the drive and rub the contacts (yellow stripes) with an ordinary eraser. You can also wipe the contacts with a cotton swab dipped in alcohol.

The card is just broken

No electronics are immune to damage. Therefore, if you have tried all the previous steps and are not successful, it is possible that the SD card is simply faulty. To check, install it in another device (PC / smartphone). If the result is the same, the drive may be dead.

It is economically unprofitable to restore it in specialized services, and it is not always possible. It's easier to get a new, more reliable one.

Defective memory card slot

If your smartphone technically supports your drive, and it functions without problems in other devices, then there may be problems in the drive installation slot. To check this, insert another drive into the gadget. If the device does not see it either, then it makes sense to take the phone to a service center for diagnostics.

Why the phone does not see the SD or microSD card - all solutions

The owners of smartphones with the Android operating system are wondering - why the phone does not see the microSD memory card? This happens infrequently and can be caused by various factors. I have collected all possible causes and solutions in this article. The material is weighty and will certainly help get rid of problems with the "invisible" SD not only on mobile gadgets, but also cameras, cameras and other devices that have a slot for expanding memory.

The phone does not see the memory card

Why is this critical?

In most cases, the phone has its own internal storage, and an external card is used to increase the amount of "storage". Imagine that we have specified third-party media as the main location for saving photos, videos, applications in the device's settings. But it suddenly stops working correctly, the system does not see it, and all data is sent to the integrated memory. And when free space becomes insufficient, often, the gadget starts to "glitch".

Let's say you decide to remove the defective card and replace it with a new one. But the problem may not go away. You didn't expect that, right? Such things can make device owners pretty nervous. I think that's enough theory and assumptions, it's time to move on to specific steps. There will be a lot of them, for all occasions.

Standard procedure

First, we will consider the basic steps for troubleshooting, and later in the article I will tell you in detail all the possible causes and methods of correction.

If the phone for some reason does not see the memory card, you should:

  • Perform a normal reboot (turn off-turn on). This sometimes helps to get rid of software glitches. Did not help? Let's move on to the next solution;
  • We turn off the smartphone, remove the back cover, remove the battery and wait a couple of minutes. Then we return everything to its place and check the operability of the microSD:

Removing the smartphone battery

  • Suddenly the previous option did not work, we try to remove the "card", check the integrity of the contacts and put it back tightly:

Inserting a memory card into your phone

As soon as you do the above manipulations and do not get a positive effect, proceed to viewing the methods below.

Incorrect SD format

If the phone does not see the memory card - it is likely that it has an incorrect format File tables Or it is damaged.

Possible reasons:

  • Memory markup failure;
  • The user produced formatting with incorrect settings;
  • MicroSD previously worked with an unknown gadget file system, has a specific markup that Android does not perceive.

Methods of elimination:

Most modern flash drives with a volume of more than 32 GB are marked in EXFAT format, which "see" not all phones (especially outdated models). Therefore, if your external memory has a similar size, it is necessary to pre-copy the important data on the computer, insert the card into the smartphone / tablet, Go to Recovery mode , Select the "WIPE CACHE Partition" action for formatting and creating a FAT32 file file table. It is perceived by all devices without problems.

Formatting memory in Recovery

Similar actions are better to entrust professionals if you are new in this matter. Otherwise, you can accidentally choose not the part and lose all data on the phone Samsung, Lenovo, etc.

But I would recommend a simpler and reliable option - use the application SD Formatter. which is installed on the laptop. You need the presence of a cartride. I recommend to see the following video explaining the procedure for working with the program:


You can make a procedure and built-in Windows tools. I already talked about them in the article link . But now I repeat.

  • You can connect a phone with a computer by cable, but I would advise to clean the experiment to apply a card reader. Any suitable. I, for example, is this:

USB Card Reader

  • Insert a card directly into it directly or through an adapter (depends on the presence of certain slots in the reading device):

microSD-to-SD adapter

  • When connecting to the PC, go to "Explorer" (my computer) and a new disk should be displayed there. Click on it right mouse button and select the "Format" command.
  • A window will open where you specify the FAT file system (EXFAT). Other parameters do not change, immediately click on the start button.

Windows formatting utility

It extremely rarely helps another option - choose the type of FS - NTFS. Some devices can work with it. It is worth trying if nothing else helped.

Some guru on the forums advise to resort to

Low-level formatting

But it is worth being neat with these things, because not all memory cards are compatible with special software.

What if there is no computer next? You can use the built-in Android tools. But not in all versions there is a similar functionality. You need to go to the "Settings" and in the "Memory" section to find the "Format SD" line (can also be called "Clear SD"):

Removing information from SD in Android settings

Do not forget that all data will be completely removed with the minimum probability of subsequent recovery. Please note that there is also a safe extraction button in the specified menu. This is no accident - you need to resort to such an event every time you want to pull the microSD card. So you will not harm the information stored on the carrier, and extend the life of its operation. But, alas, many are used to using "hot extraction" right in the process of work. This is not entirely correct and can cause failures.

MicroSD non-working, failed

Probable reason:

It can be like mechanical damage to the carrier and thermal (due to strong overheating), as a result of which the SD card stopped working not only on the tablet, but also on any other device.

How to fix:

Unfortunately, in such cases it is customary to say: "Medicine is powerless ...". Nothing can be done, except to purchase a new drive. Alas, it will not be possible to save the lost data either. That is why I always recommend backing up important information - in the "cloud", on your computer's hard drive. As practice shows, "dancing with a tambourine" is useless here. Don't waste your time looking for a "life buoy". Life is harsh ...

If you bought a USB flash drive in a store and it is still covered by the manufacturer's warranty, then you can try to exchange it for a new one. But for this you need to provide a sales receipt, the goods should not have visual damage.

Banal incompatibility

Why else can't the phone see the microSD card? It happens that a new generation drive is not supported by some smartphone models. Or, its volume exceeds the permissible performance of the gadget. For example, Samsung J120 is "friendly" with external storage media up to 64 GB, and you purchased a 128 GB flash drive. Here is the cause of the problem. It is necessary to clarify such moments in advance, so as not to get into a mess later.

The computer does not see the SD card either

Situation: we connected a mobile gadget to a PC via a USB cable, the phone screen displayed a choice of connection modes, indicated “Mass Storage”, but the new “storage” was not displayed on the laptop.

The solution is simple: just disconnect the device and then plug the cable back into the laptop, but now you need to select the "Media Device" (MTP) mode.

Media data transfer Android

Do not "contact"!

If someone "crooked" (not you) tried to insert the card into the slot with the wrong side, showed excessive persistence, then the connector could be damaged - the contacts came off. Or, on the microSD itself, the tracks are oxidized / wiped out.

It is necessary to carefully examine all the objects described above. Perhaps you should just pull out the drive and insert it correctly. Suddenly the problem is in the contacts, they can be replaced, but with this problem it is better to contact the service center to the specialists.

Inserting a memory card into your phone

The phone stopped seeing the memory card: a failure at the software level

Diagnosis: a certain Android application does not recognize the external storage, while others do it without problems - recording, playback is proceeding as expected.

What to do? Most likely, a different location for saving data (internal "disk") is specified in the utility settings. It is enough to open the parameters and make the necessary changes. This behavior often helps to eliminate defects in the standard "Camera" and "Gallery" software.

Useful videos

Instructions: how to check the SD card for errors:

Question answer

Further, useful information will be presented in the format of answers to frequently asked questions from readers of various forums and thematic resources. I have collected the most valuable recommendations. Perhaps among them there is a solution for you.

I got a new SD memory card for Samsung J320, inserted it into the phone and through Explorer moved all photos and videos from internal storage to external storage. I wanted new pictures from the camera to be automatically saved to microSD. But this did not happen - the pictures are placed in the Samsung memory, as before.

Most likely, the Camera application needs to be reconfigured by specifying in the settings to save snapshots and videos to external media. If it doesn't work, turn off the gadget, remove the card, insert it again and boot anew.

The SD card is not detected only on the Lenovo A560 smartphone - but the computer sees through the card reader, the second Lenovo phone is also visible. When I put another flash drive to myself, it works without problems. Tell me what is the problem?

Prestigio stopped seeing SD memory card. How it all happened: I just played Slither.io , then they called me. I talked for about ten minutes. When I finished, there was an inscription in the notification line - "Safe removal ...". I looked in the settings, where all the available drives are indicated. In the "External ..." section, two options are displayed (instead of volume): connect and clear SD. First, I clicked on the first, for a couple of seconds the inscription was displayed: "Connecting ...", then "Search for errors" and silence. Rebooted, extracted - the same effect. And on other smartphones, a similar problem. Help me please!

On Windows Phone DS 535 microSD stopped being detected recently. I put on other devices - it works (camera, tablet). Is this a phone defect?

I have Fly. Yesterday I cleaned the memory through the optimizer 360 Total Security and after that the phone does not see the card. I put a new one - the same trouble. I suspect that the program killed important system files. Can this be?

For all of the above situations, the procedure is as follows: first, we determine whether the PC sees the memory card - we use a card reader for this purpose. If it does, then we copy important data to the hard drive and proceed to formatting. You will need the SDFormatter utility (it was mentioned above in the article). Suddenly it does not help, then the media is completely damaged and needs to be replaced with a new one.


After restoring photos using one of the utilities, the images fit into the program folder, but they are not visible in the Gallery.

The problem here is not the card. You should go to any file manager (or through a PC) and transfer the recovered snapshots from the application directory to the DCIM directory. Then they should become visible to the device.

It was necessary to temporarily move the card from the phone to the tablet, and after these manipulations, the data on misroSD disappeared. You see it, but it looks like it's empty.

Most likely, you inserted the SD incorrectly during the swap. Try to remove and reinsert, after turning off the gadget.

I just bought a 2 GB Qumo microsd, but my Samsung Galaxy A5 for some reason does not identify it. I tried it through the cable to the laptop, but Windows does not see it either. Maybe I'm doing something wrong, tell me?

Immediately, I note that the products of the Qumo company do not have the best reviews. We recommend connecting the card directly to the PC using a card reader. If it still does not work in this case, then it is worth returning it to the store until the exchange period has passed according to the law (14 days). BUT, suddenly everything is fine on your computer, then try to format it with the SDformatter utility.

I bought a Galaxy S5 phone not so long ago, and literally a month later it stopped detecting external drives (tried different ones). For others, my SD card works flawlessly. Why does Android not see the USB flash drive on Samsung, can this be fixed?

It is likely that the negative behavior in this case is caused by the following factors - USB debugging is disabled on the smartphone (try turning it on), the drive has a file table format that is incomprehensible to the gadget. Try formatting with exFAT.

The tablet fell to the floor, and after that all photos disappeared from the Gallery. In the file manager, the card is visible, there are folders on it. But there are no images.

With mechanical damage, this happens. Most likely, the card has shifted inside the slot - you should align it. If it does not help, we try to insert it into the card reader and connect it to the computer. Suddenly you won't see a photo there either, then I advise a utility for a PC -


for data recovery.

Such a nuisance happened - I bought a brand new Samsung J7 and wanted to transfer some valuable data from an old smart (also Samsung). Everything seemed to go smoothly, there were no mistakes.

But a week later I noticed that the transferred files were gone. I opened the explorer - all the folders are in place, but they are empty. And where the information has remained, it gives an error when trying to reproduce. The strangest thing is that I rearranged the card into an old gadget - everything opens and displays without any problems. By the way, after a reboot, sometimes the problem disappears, but not always. Is there a defect in the phone? What should I do, advise.

I would recommend saving all important data on an external storage device (hard drive, cloud). Then format the microSD card to FAT (use SD Formatter -


above in the article), and on your phone, do a factory reset. One more thing - before proceeding to such drastic measures - try to remove unnecessary software and check for updates. It is likely that this is a firmware issue. Then you need

enter the recovery menu


I have already tried everything, read a lot of forums. The last hope is on you. I have a Chinese (non-original) Galaxy 5. Since recently, it has only seen the internal drive, but the microSD does not detect it.

The question is not entirely specific. If the card is not identified in specific applications, then the problem may be in them. Try to revise the software settings, reinstall it. I recommend checking the drive itself on another device or connecting it to a PC. It is likely that this will not give a positive result, then it is worth taking a known working carrier and testing the work with it.

Generally a paradox. At first, the memory card stopped working normally. I reconfigured saving from applications to internal. Then, in general, full ATAS - as soon as I turn off the external drive, and the built-in one stops being detected. The phone does not see it, as if there is no storage at all. Although Android works, its files are stored somewhere.

Most likely, the file table of the map is out of order. I do not exclude the possibility of a viral infection. Be sure to remove it from your phone, connect it to your PC and check for viruses, then format it to FAT32. If after the operations done nothing good happens, reset the smartphone parameters. In this case, all data will be deleted, alas.

On a computer, the card works fine, I'm not complaining. But as soon as I insert it into the tablet, it writes "Safe removal ...".

I picked up a virus via e-mail. I tried to delete it - it didn't work. We were advised to enter Recovery and restore the firmware. When it rebooted and followed the recommendations, the smart started, but something went wrong - the phone does not see the memory card at all. I started playing with custom firmware - it didn't help.

In both cases, there is a violation of the microSD file table due to a crash or virus attack. This situation is corrected by formatting the external drive. And you shouldn't "play" with unofficial software, it is better to flash it exclusively with proprietary software.

I bought a 4 Gb flash drive, pre-recorded music and photos from the computer on it, then inserted it into Lumiya 530. I used it for a couple of days, then I used the card reader again to upload the pictures to the computer. But Windows reported that the device is not recognized or damaged. He sees on the phone, the computer does not. I tried others - no problems.

Obviously, the defect lies in the PC. Try to connect different flash drives to it - will there be a similar reaction. Test different USB connectors, some of them may be damaged. Sometimes the system itself blocks the ports. Read


on this occasion.

On Nokia 6 I use a fourth class Mirex micro-flash drive. A couple of days ago, I normally listened to music through the player, and today I write that there are no audio files. Is the card covered or how to check?

Don't jump to conclusions. You need to check if the external storage is visible to other applications installed on Android. Maybe this is a "glitch" of the player. If other programs are not detected either, you should connect the media to the computer through a reader (card reader). If it is not readable on a PC, then try the other methods discussed in this publication.

My smartphone is not that old - Samsung A3 (model of 2015), but I can't see the SD card. Already formatted, but it did not lead to anything. It is easily detected on a laptop. But the phone does not see the USB flash drive - why?

I advise you to open the Android "Settings" and in the "Memory" section view the "Memory card" item - is the total and occupied space shown there? You can also install a third-party manager (Explorer) from Google Play, for example, ES. In it, also look - whether the media is visible, whether the folders on it are displayed. If you tried to format, then you should also refer to the Low-Level Format procedure. Read about her



I bought a Chinese Dugi X5 on my head. I worked for six months without any complaints, but then the problems began. First, I rebooted, the Google Play services settings were flying. And now this is also - I bought a microSD for 16 gigs, transferred pictures, personal videos from the internal drive there. And then they disappeared. The smartphone does not see the memory card at all. I did a recovery through Recovery - all the same. We need to save files, help!

If you cannot perform the necessary manipulations on the device, it is worth connecting it to a PC. Better yet, remove the card and connect it directly to the personal computer. Then, to save files, I recommend running the CardRecovery utility. Otherwise, follow the steps outlined in the other answers in this article.

The SD card has been removed for use in the camera. Then he returned it back, but he stopped taking it. How to fix the situation when the phone does not see the memory card? And the laptop also does not detect it.

It is possible that the camera is using its file table and may have made changes to the drive. This happens very rarely, but if the markup fails, then you should run the Disk Management service on the PC. Click on Win + R , then write the command "Diskmgmt.msc" ... A window will open where your drive will be displayed as an unallocated area (navigate by volume so as not to accidentally select a hard disk partition). Now we click on the necessary block with the right mouse button and create a new volume. After a couple of seconds, the flash drive should become visible on both the PC and the phone.

I always do everything according to instructions, no amateur performances. Yesterday I bought a new fotik, connected it to a laptop via USB cable, but in My Computer, instead of a removable media, it is shown as a portable device. When I open it, I see only 16 MB of built-in memory, but the camera sees the SD card, but the PC does not.

In order not to bother, just purchase a card reader for the SDHC connector and insert the card there. So the laptop will definitely "make friends" with the carrier.

To increase the available space in the tablet, I purchased a microSD of 32 GB. It is inserted from the side into the body of the gadget. I noticed that the first time I put it, it seemed a bit taut. But I didn't bother. Now such a misfortune - periodically writes "Extract ..." and the card becomes unavailable. Just press my finger on it a little - and it turns on again. I understand that the slot is damaged?

DO NOT jump to conclusions. I advise you to first put your card in another device, and in your gadget, too, a working drive. To narrow down the “circle of suspects”. But, as I understand it, you have a problem with the connector pins. Be sure to turn off the tablet and try to gently bend them back to their original position. But it is better to turn to specialists so as not to turn everything there at all. If another card works without glitches, then take your own and format it by choosing the FAT32 table type (you can use a PC in the standard way or through SDFormatter).

MicroSD 32 Gb new, I checked it in the store - everything worked. Connected at home - does not see her phone. I put my wife on my smartphone - also not. At work, we tried ten phones - the same thing.

You did not provide enough information. One could answer that the card is not working and you need to carry it to the store for a return / exchange. But, chances are that this 32GB storage capacity is simply not supported by all the devices you tested on. Have you checked on your device in the store? I can’t answer specifically, because you described the situation vaguely. It is best to go back to the store where the SD drive was purchased.

An incomprehensible problem - the card is seen on the Texet 5570 smartphone, but information cannot be copied or transferred to it. That is, it seems to be there, but you cannot use it.

100% - you need to format the media using a computer and the SDFormatter utility. Only be sure to specify exFAT (or FAT32) in the procedure parameters. I also had this, it was such manipulations that helped to eliminate the defect.

In the evening, the tablet turned off by itself, although the battery was charged. I then turned it on and did not immediately notice that the SD card was no longer displayed. In the notification line it says "Connecting ...", but the process is delayed and there is no positive result. As a result, most applications do not start - it gives an error. And it is also impossible to transfer them to the internal storage. But worst of all, the gadget slows down so much that it stops responding to my commands. It hangs, you have to wait until it is discharged and turned off. Alas, I don't know how to reset. But when I take out the microSD media, the load immediately decreases and the tablet works, only without the programs necessary. According to your instructions, I formatted it in different ways, changed the card. Sometimes mine is displayed, but as soon as I try to view a photo or video in the Gallery, the "brakes" start again. I did a reset, I tried Recovery - nothing. The strangest thing is that the computer perfectly sees the memory card, copies, reads from it.

The problem is quite extraordinary, if you described everything correctly. The drive is likely to be in order. But something is wrong with the tablet. Alas, even a reset does not guarantee a return to normal if there are hardware defects. Either there is a malfunction in the slot, or in the chip that controls it. I recommend contacting the service center so that the specialists can carry out diagnostics.

The initial data are as follows: there is a Lenovo Vibe with Android version six, a 32 GB Sony card. On the computer, it is displayed in two sections, everything is fine. The phone does not see and displays the message SDCARD 0 Kb. That is, as if it were empty. It is important for me to get access to the photos, as they are very valuable to me. By the way, the PC sees the drive, but does not open it.

If you want to recover images, there are many useful applications. Look




... Try not to do any other manipulation with the media before scanning. This will increase the likelihood of successful recovery of all pictures and videos.

I bought together a new Samsung A3 series and a 64 Gb Samsung card for it. I connected it to my PC and created folders with music, movies, photos, documents and a few more in my memory. But then I discovered that the smartphone does not see some of them at all.

It is likely that the built-in Samsung explorer may not understand some folders because of their names (in Cyrillic). But if you install a third-party ES file manager via Google Play, then it should show all the content. But if new errors begin to appear, then it is better to copy important data to the hard drive, and then format the USB flash drive.

Lenovo stopped seeing the memory card. After switching on, immediately in the status bar it says "One SD card is available, switching is impossible". We put it in other smartphones and tablets, connected it to a computer via a card reader - all in vain. And how many photos and videos from holidays and travels are left there. Help, I'll pay how much tell me!

I don’t take money, although thank you for the offer! Let's leave aside the worst scenario for now - the card is completely out of order. Let's hope the markup just flew off. This article above provides advice on starting the diskmgmt.msc (Disk Management) service. Here you need to view - whether the flash drive is visible there, how it is displayed (type of file table or not marked area). If anything - create a new volume. The microSD card should be detected on the PC. It remains only to perform file recovery with any suitable utility (also see the links in the contents of this publication).

I decided to encrypt the data on the SD card to protect information. And now the files are visible, but I cannot open them. Even through the program that I used to crypto. The same thing on a computer - he sees folders, but does not reproduce anything. SDFormatter is not an option as you need to preserve the information. What to wish, tell me.

Look carefully at the other situations and answers, there are a couple of suitable options. I also advise you to connect via a card reader to your laptop and

run command line

, write the command there

chkdsk X: / f / r -

where X is the drive letter assigned in Explorer (My Computer). This will check and fix write and read errors, and physically damaged sectors.

When I connect a Kingston flash drive through a card reader to a laptop, I write - "The device can work faster." And sometimes it's cool - the card is not recognized.

There is very little information, but I will try to answer. If the drive is USB 2.0, and the laptop is old and it has ports that support the first version of YUSB, then there may be such an error. Or is it worth

update driver

chipset. Then it can work fine.


It seems like he provided a lot of solutions and tips, but you can always contact me in the comments or on the page " Questions and Answers ".

I often heard that people bought goods in a hardware store, and sellers were convincing that the products are checked in the warehouse and there is no point in unpacking them at the time of purchase. Everything is working and with a guarantee. This is especially true for flash drives that are tightly sealed in a plastic box. And then at home it turns out that the drive is inoperative or incompatible with your gadget. Be sure to check the specifications of your device before paying in the market, how many "gigs" you can expand its storage. Now in online stores, customer reviews are a useful tool - be sure to read what people write. Sometimes there you can see interesting nuances that affect the choice of a particular product.

As soon as you have determined that the purchased memory card is defective - do not pull it, immediately bring it back for exchange or refund.

And yet, if you do not feel confident in your computer knowledge, then it is better not to take risks, but immediately ask specialists for help. These can be both experienced acquaintances and employees of service centers. I do not recommend contacting small workshops, where they can cheat for money, presenting a banal malfunction for a critical breakdown. And then they may also say that the reason was in viruses, they will also impose on you the installation of antivirus software for 1000 rubles. This happens all the time.

In most cases, the steps described in the publication help you understand why the phone does not see the memory card. Unfortunately, in one incident out of ten, a media breakdown is recorded without the possibility of its recovery. Hopefully this is not your situation.

We will talk about a microSD memory card, which for various reasons ceases to be seen by a smartphone with an Android operating system, and about methods for eliminating this problem. Users of mobile gadgets rarely encounter such a difficulty. Nevertheless, if it does arise, then it certainly brings some difficulties. We will tell you what to do if the smartphone does not see the map on the smartphone.

The smartphone does not see the memory card - what to do?

Why is it important?

The memory structure of a mobile phone usually includes an internal storage and an external card. ... It expands the gadget's own memory to the required value.

It happens that the user wants to store his photos, video files, applications mainly on a third-party medium, that is, on an external memory card. I went into the settings and indicated MicroSD as the main save location.

If suddenly there are interruptions with the external media, the system ceases to see it, then the data that was previously on the card migrates to the integrated memory of the phone. It has a significantly smaller volume. Then, due to the lack of free space, freezes and other troubles with the gadget begin.

Let's go through all the steps that need to be performed in order to eliminate the troubles associated with the fact that the smartphone does not see the microSD memory card.

Basic manipulations

The first thing to do when this malfunction occurs is to perform a simple reboot or turn off the gadget and then turn it on. Software glitches, which sometimes lead to the fact that the smartphone does not notice the card, can be eliminated in this way. What if the problem persists?

Then try to remove the cover from the device, then remove the battery and wait a few minutes. Then reconnect the battery firmly and close the cover. Again, to no avail? You should check the quality of the contacts of the external card and their tightness. Remove the memory card and inspect the contacts carefully for integrity. Then put it back in the slot.

If all else fails, then the problem has arisen at other levels. Let's list the remaining possible ways to eradicate it, analyzing in detail the question: "why the smartphone does not see the memory card?".

Wrong memory card format

Of course, the card itself can be damaged. But before rushing to conclusions, you need to check: what if it has a file system format incompatible with a smartphone?

This inconsistency arises for several reasons. There may be a memory markup failure or your card has already worked with file markup that your gadget does not understand. In addition, the markup may be such that Android basically does not understand it. Or maybe you did the formatting yourself, not paying attention to the fact that the settings were chosen incorrectly? One way or another, the smartphone does not see the MicroSD. What to do?

If your card is comparatively large in size, and it is over 32 GB, the problem probably lies in the following. Outdated and even some modern phone models simply do not accept the format in which most flash drives are marked up today. This refers to exFAT. Then the way out is to reformat the MicroSD and create a table of files of a different type - FAT32.

We recommend that you contact the professionals, because by choosing the wrong section, you can lose all your phone data altogether. But if you're sure you can do it yourself, here's a quick step-by-step guide on how to do it. Don't forget to back up your map to your personal computer or laptop first. Put the card into the gadget and enter Recovery mode on it. Next, you need to select "Wipe cache partition":

This will result in formatting. This will create a FAT32 file table that any device can read without difficulty.

Computer to the rescue!

A more reliable way is associated with the involvement of a computer in the process. The SD Formatter application is installed on a computer or laptop. You also need a device such as a card reader. How to work with this utility can be found in numerous videos available on the Internet. If you don't want to download a third-party program, you can use Windows Internal Reserves. You can connect your smartphone and computer with a cable, but it is preferable to use a card reader. Let's consider this particular option.

First you need to insert a MicroSD card into the reader. Depending on the available slots, this can be done directly or through an adapter:

Now we connect the card reader to a personal computer. The "My Computer" section should display the new drive. After right-clicking on its image, select "Format". In the window that appears, you need to set the FAT or exFAT file system without changing other parameters. We start the process by pressing a button:

Choosing a different type of file system, NTFS can also sometimes help. But a very limited number of smartphones work with this format.

These are the techniques that involve a computer or laptop. And one more thing: use special software for low-level formatting with caution. Not all types of microSD cards are compatible with it.

Android Formatting

If you don't have a computer at hand and your smartphone can't see your SD card, try using the internal tools of your phone's operating system. This is possible if available in the Android version of your mobile device.

To do this, open the "Settings", in the "Memory" section of which, find a line called "Format SD" (or "Clear SD"). We would like to warn you: all card data from it will be deleted, and they can no longer be actually restored:
To do this, open the "Settings", in the "Memory" section of which, find a line called "Format SD" (or "Clear SD"). We would like to warn you: all card data from it will be deleted, and they can no longer be actually restored:

By the way, this menu contains another useful item - "Safe Removal". This function should not be neglected, since "hot eject", that is, performed right in the process of work, can itself cause problems with the card. Competent removal of the card not only preserves its data, but also prolongs the service life of the device.

If the card itself does not work

A malfunction can occur directly in the card itself as a result of mechanical damage or severe overheating. Unfortunately, in this case, there is nothing left to do but try to exchange it in the store where it was purchased for a new one.

To do this, the failed card must be covered by the warranty period provided by the manufacturer. In addition, the device should not have any visible damage, and you will have to provide a receipt for purchase. It is for this reason that we strongly recommend backing up your most valuable information. In addition to computer and external memory (hard disk), you can resort to "cloud" resources.


It happens that you bought a completely new microSD card, and it did not fit the smartphone model for obvious reasons. It's just that the phone of this series does not support such cards, or it does not have the ability to work with cards of this size. And you did not know about it. It's a shame, isn't it?

We advise you to show elementary attentiveness to the "little things" so that such a situation does not arise. Check with the consultants whether a particular "card" is suitable for your smartphone. A smart solution would be to simultaneously purchase at one point both a mobile gadget and an external carrier for it.

Checking for errors on the computer

Another point related to the situation when the smartphone stopped seeing the memory card. This is an attempt to restore external media containing bad sectors using a personal computer.

The smartphone does not see the memory card - what to do?

To do this, you need to connect the card to the computer using a card reader or other reader. Going to the "My Computer" folder, find the displayed new disk, right-click on it and select "Properties":

A menu will appear where you should select the "Service" tab. A window will pop up, in which you need to find the section "Checking the disk for errors". There is very little left. Click the Run Check button to display the progress window of the process. In it, you must check the boxes in both boxes: "Automatically fix system errors" and "Check and repair bad sectors". Now click on "Run":

The smartphone does not see the memory card - what to do?

A check will take place, at the end of which the checked and corrected card must be returned to the slot of the smartphone or tablet.

If you need help, please contact the specialists of the Good Deeds Service. We solve the problem using remote access or we will promptly visit you. Leave a request through the website or give us a call - and in a few minutes the problem will be solved!

Despite the wide range of smartphones with a large amount of internal memory, variants of phones that support the installation of memory cards do not lose popularity. On such a removable medium, you can store various information: videos, photos, text files and other types. Active users of such media often have a question why the flash drive is not visible on the phone.

What should you do first if your phone stops seeing MicroSD?

There are several main reasons why the flash card cannot be read by the device. Before looking for an answer to the question why the phone does not see the SD card, you need to try to restore the operation of the carrier yourself. To do this, follow the instructions:

  1. Restart your device. To do this, hold down the power button for a few seconds, and then select "Restart" from the menu that appears.
  2. Many devices that support a memory card have a removable battery. If you have this model, remove the battery for a few seconds and then reinstall it.
  3. After another test of the card's performance, which was unsuccessful, carry out another test - remove the microSD and clean its contacts with a soft cloth. Also check the quality of the contacts in the slot (they must not be deformed or oxidized).

If the preliminary measures did not work, then you can look for the reason why the phone does not see the memory card. The reason may be in the media itself or in the device. If the serviceability is hidden in the flash drive, then it will have to be replaced - the cards are not suitable for repair. As for the smartphones themselves, in case of malfunction, you can try to fix them yourself or at a service center.

We fix the unsuitable format of the drive (memory card)

how to format a memory card

The most common reason why the phone does not see the SD memory card is the wrong file system format or the presence of bad sectors. Usually, when connected to a computer, such cards are not read, they give errors, ask for formatting. The reasons for such a malfunction of the flash drive can be:

  • the Android operating system does not understand the markup or file system that the drive is working with;
  • memory markup failure;
  • the user has formatted with incorrect settings.

Usually the reason is trivial - manufacturers prepare modern flash drives to work with the exFAT file system, which is not perceived by all devices. This problem is eliminated by formatting the media. It can be produced in several ways:

  1. Formatting in FAT32 can be done using the Recovery mode. This method is laborious and not very convenient, since you have to go to the system menu and look for the desired item. We will not give it, as there are better methods for solving the problem.
  2. SD Formatter utility for PC. In this case, you will need to install a free program on your computer and insert a USB flash drive into it using a card reader. If you have a laptop, then most likely you have an SD compartment. Along with microSD cards, adapters are sold that are just intended for this slot. It's easy to manage the program - you need to select your card from the list of hard drives, and then stop at the "Format" item in the menu. Before starting the process, you need to select the file system that you want to use in the future on the media.
  3. Using a standard Windows tool. The only difference between this option and the use of a special utility is that the formatting option is invoked by right-clicking on the name of the media. You can connect a USB flash drive using an adapter. There is another option - to use a standard cable and use it to connect the phone with the carrier installed in the slot. The second method for detecting media by a computer should be used only in extreme cases.
  4. Android operating system has another built-in way to help you solve the formatting problem. In the memory management menu, there is a "Formatting SD" function, you can use it. This feature is worth using only in cases where the smartphone detects a card, but cannot use it due to an error occur.

In most cases, simple formatted you can solve the problem. If this option did not come up, continue the search for the reason why the phone does not see the flash drive.

MicroSD failed

The second common cause can be a complete failure of a memory card. In this case, it will not be detected by a smartphone or a computer. The causes of the breakdown can be:

  • frequent reinstalling of the media without using the preset mode;
  • overheat;
  • mechanical damage;
  • Oxidation of contacts due to moisture.

In this case, even restore files from a memory card will be difficult. You should replace the carrier to a new one.

Incompatibility of the memory card

Buying a new memory card for your smartphone, you need to pay attention to the manufacturer's recommendations. One of the frequent reasons why the Samsung phone does not see the memory card, is the wrong choice of its size.

For example, the J120 model supports media with memory capacity up to 64 GB, while users wanting to maximize the "pumping" the device is installed in it with 128 GB. This flash drive will not perceive the smartphone, even after formatting it in the correct format.

No contact in a smartphone slot

You can find this reason yet at the preliminary preparation stage. Often, users damage contacts in a slot to a memory card, inserting it not to that side. In this case, the reading arcs can bend or even break away.

Also on the tracks may appear oxide or falling. In the latter case, it should be carefully lost to them with a piece of elasty or a napkin, barely moistened in alcohol. After that, try to insert the drive again if this attempt is not crowned with success, contact the service center. There you will be able to replace damaged contacts and restore the slot.

Software failure
the phone does not see the memory card

If there is clear reasons why the phone does not see the micro SD flash drive, you did not find it, you need to check the software. To start, reset the settings to the standard, and then in the "Storage" section, set the file saving option on removable media.

With a software failure, which failed to get rid of simple adjustment of options or reset the settings, it may also be necessary to update the device firmware. This procedure will allow you to get rid of critical errors of the system and change the interface to more friendly. If you yourself do not know how to reflash smartphones, you should seek it to those skilled in the art.

Now you know all the reasons that can lead to a failure in the work card of modern smartphones. In most cases, the failure occurs due to the incorrect work of the card itself, since MicroSD is quite fragile. In order for the carrier less frequently, buy modern cards, with high data processing speed and sufficient level of reliability. If you have any questions, ask them in the comments. With a failure in the work card, everyone may face, so it is worth share this article with friends.

Memory cards (microSD) are often used as additional data storage on mobile devices. Losing access to this storage can be a real disaster for the user, because many keep photos and other personal files on them, which often exist in a single copy. In addition, access to applications that were located on this medium is lost.

Why does the phone not see a memory card or USB flash drive, which worked and was readable yesterday? How to solve the problem on your own?

How to find the culprit

The source of the problem can be software and hardware errors both in the memory card itself (flash drive) and in the phone.

The reason is most likely in the card (flash drive), if:

  • It is either not detected or defined, but not read by different devices.
  • It stopped reading immediately after using it on another device.
  • It has visible mechanical damage.
  • When the card is inserted into the slot (USB flash drive is connected), the phone freezes, restarts or turns off. Provided that it responds normally to other removable media.

The culprit is most likely a phone if:

  • It does not detect or detect, but does not read any microSD card or USB flash drive.
  • When you install any card or connect any flash drive, it turns off, reboots or freezes.
  • The card slot (USB connector) has visible mechanical damage.
  • The failure was immediately preceded by any actions with the phone: installing applications, updating the firmware, anti-virus scanning, resetting to factory settings, etc. Or accidents - bumps, falls on the floor, etc.

When connecting flash drives with a full-size USB type A connector to mobile gadgets, OTG cables and adapters are used, which are also often the reasons for such situations.

Unfortunately, in many cases there are no obvious signs of the "guilt" of one or another device. For example, when a card or flash drive is not recognized by a specific phone, while others read it normally, and the phone reads all drives properly, except for this one.

Because of what memory cards and flash drives are no longer recognized and read

In about half of the cases, the failure is caused by a drive failure. CompConfig.ru has already talked about the types of breakdowns in USB flash drives. The same can happen with a card. In addition to the described problems, they quite often have one more - the formation of an oxide film on the surface of the contact group, which creates an obstacle to the exchange of data between the card and the phone. In addition, being small and fragile, micro SD cards break easily mechanically, much more often than flash drives.

Another group of reasons is of a software nature, that is, it is not associated with the drive, but with its contents. Among them:

  • Unrecognizable file system. This can happen if the card or flash drive was previously used on a Windows PC and formatted in NTFS. Or it was in another smartphone and was formatted in exFat. For removable media to be readable on any version of Android, it must be formatted to FAT32.

  • The removable storage is infected with malware. The reason for the lack of access to it may be the blocking of the antivirus that runs on the phone, or the actions of the malicious program itself.
  • The file system of the memory card or flash drive is damaged. Reasons - incorrect shutdown (for example, during recording), use on a faulty device (including connection to a faulty reader or adapter), unstable power supply, viruses, etc.

Why does the phone not detect or read memory cards and flash drives

Phone reasons can also be hardware and software. The first group includes:

  • Mechanical damage to the memory card slot or USB connector. Often easily identified by eye. In this case, the phone will most likely not recognize any SD cards. And if the USB socket is broken on it, then there will be problems not only with reading flash drives, but also with charging.

microsd card slot

  • Malfunctions in the electronic components of the board. A failure can be manifested by the fact that when you install any drive in the slot, the phone hangs tightly, reboots, etc. Or an apparently undamaged slot and a working card are not detected in the system in any way. Or they are determined and disappear.
  • Malfunction of devices connected to the phone (SIM cards, etc.). It manifests itself in the fact that problems with recognizing a memory card (flash drive) arise only when connected together with a faulty device.

Software reasons:

  • Incompatibility with microSD cards of a certain type or size (no driver). In such cases, cards can be identified, but incorrectly and without access.
  • Failure in the operating system. It is manifested by errors "SD card does not work" and other similar ones. Or the removable media is not detected at all.
  • Installing blocking applications.
  • Virus infection of the phone.

How to fix the problem yourself

Below is a sequence of steps that will help you fix the problem in about 80% of cases (in the rest, only a service center or buying a new drive will help out). If the previous action did not give the desired result, proceed to the next one. Recommendations for flashing devices are provided rather for reference. They are performed at your own risk.

If the likely culprit is a card or flash drive:

  • Make sure there are no mechanical damage to the drive. Some of them (connector blade) can be easily removed with your own hands if you know how to use a soldering iron.
  • Clean the contact group of the memory card with an eraser or rubbing alcohol. This will remove the oxide layer from their surface and restore signal transmission.

memory card contacts

  • Connect the media to your computer (if you are using a reader or adapter, make sure they are working properly). Make sure its file system is supported by your phone. If not, format to FAT32. Do not forget to first copy the information from it to another medium, for example, to your PC's hard drive.
  • Scan the media with an antivirus program.
  • Check it for file system errors. To do this, you can use a standard Windows tool (the chkdsk utility, which is used to find and fix disk errors): open the drive properties in the explorer, go to the "Service" tab and click "Check". In the next window, check "Automatically fix system errors" (by the way, in Windows 10, automatic error correction is enabled by default, so this window does not appear).

checking disk for file system errors

  • If the probable cause is a failure of the proprietary software (firmware) of the flash drive, in some cases it can be restored using the service software that can be found on specialized web resources. However, after this procedure, no data will remain on it. In addition, in case of unsuccessful firmware, the drive may completely fail.

If the likely culprit is your phone:

  • Make sure there is no mechanical damage to the memory card slot or USB socket.
  • If the slot has not been used for a long time, dust may accumulate in the slot. If possible, remove it with a brush or dry cotton wool wrapped around a toothpick. If the slot contacts are accessible, remove the battery from the phone and clean them with alcohol.
  • Disconnect all external devices from your phone except the problem storage device and restart the system. If after that it was normally detected, the reason is in something of the disabled.
  • Scan your phone for malware infection.
  • Uninstall apps that you installed shortly before the crash.
  • Temporarily uninstall your antivirus (it may block removable media).
  • Do a factory reset.
  • Reinstall your phone's operating system.

If the likely culprit is not identified, use the recommendations from both groups that best suit your situation.

Sometimes the smartphone cannot detect the memory card and displays errors like “SD card does not work”, “SD card is not supported”, and also prompts you to format it. There are several reasons for this problem. Here are the most common problems and how to fix them.

1. Incorrect installation

First of all, try pulling out the memory card and gently reinserting it into your smartphone. Make sure it is installed correctly. There should be a distinct click in the spring loaded slot. If the tray is removable, insert the card with the indicated side and insert the slot all the way. After installing the microSD, restart your smartphone to re-initialize the memory card.

2. Mount error

In rare cases, Android does not recognize the external storage due to a software glitch. This can be fixed by removing and reconnecting the card in the settings.

What to do if the phone does not see the memory card: open "Settings" → "Storage and USB drives" What to do if the phone does not see the memory card: find your card in the "Removable storage" section and click on the small triangle opposite it

To do this, open "Settings" → "Storage and USB-drives", find your card in the "Removable storage" section and click on the small triangle opposite it.

What to do if the phone does not see the memory card: wait for the "Extracted" message to appear What to do if the phone does not see the memory card: tap the name of the microSD and select "Connect"

The caption under the name will change to Checked Out. Now tap the name of the microSD and select "Connect."

3. The presence of an unsupported file system

You may encounter this problem when using a memory card that was previously connected to another smartphone or computer. The media may simply have a different file system that your gadget does not understand. In this case, all that remains is to format the microSD into a supported format.

Keep in mind that all information will be deleted in this case! If there are photos, videos, documents and other important data on the memory card, they should first be saved - in the cloud or on a PC.

What to do if the phone does not see the memory card: go to "Settings" What to do if the phone does not see the memory card: select "Format"

The easiest way is to format the card directly from your mobile. Go to "Settings" → "Storage and USB-drives", open microSD, and then open the additional menu, click "Settings" and select "Format".

If the phone does not see the memory card, what to do: find it in the file explorer and click "Format"

If that doesn't work, you may need to complete the procedure from your computer. To do this, connect the card to the PC using a card reader, find it in the file explorer and click "Format" in the context menu. For cards with a volume of 32 GB or less, choose the FAT32 format, for larger ones - exFAT.

What to do if the phone does not see the memory card: select microSD from the list of drives and click the Format button

You can also use the free SD Formatter utility for Windows and macOS. It is useful if the computer sees the card, but does not allow formatting it. Install the application from the link, launch it, and then select microSD from the list of drives and click the Format button.

4. Incompatibility with a smartphone

MicroSD manufacturers are trying to make them as compatible as possible with any device, but still, sometimes you can face a situation when a smartphone does not support a specific card. This usually happens with high volume media.

In this case, it is worthwhile to study the instructions for the smartphone and make sure that it is compatible with cards of the required format and volume. Unfortunately, not all gadgets can boast of support for microSD for 128 and 256 GB, and in budget models, problems with smaller media are not excluded.

5. Oxidation of contacts

If the memory card has been stored separately from the smartphone for a long time and is often used with various devices, there is a possibility of oxidation formation on the microSD slot. This deteriorates contact and may cause connection difficulties. This problem can be easily solved by cleaning.

What to do if the phone does not see the memory card: using a regular eraser, gently wipe the yellow stripes on the back of the card

To do this, remove the card from your smartphone, put it on the table and, using a regular eraser, gently wipe the yellow stripes from the back. If you have alcohol on hand, moisten a tissue or cotton wool with it and further clean the contacts.

6. Damage to the memory card

If none of the above helps, then there is a possibility of damage to the memory card itself. This can be due to mechanical damage, moisture or wear. In any case, further attempts to get the microSD to work are not worth the time and effort. It is easier to purchase a new memory card and replace the failed media with it.
