Troubleshooting Galaxy S7 Edge that can’t read SD card

Problem: I have just gotten a Samsung Galaxy S7 Edge and it’s not reading the SD card correctly. When I go to the sd card files in my phone its not showing anything. The card works perfectly in my S5 and also plugged into the computer. I am trying to use my music and videos I have on the card. All the files show up on the computer. Any help would be great!

Troubleshooting: Hi! Let’s proceed directly to the issue. It might have been that your Samsung Galaxy S7 Edge can’t read your SD card, but most probably it recognizes it. To start isolating the issue, follow these steps below:

Step 1: Force Reboot The Device

This is the easiest step that you can do to your device but it can resolve minor issues. The restart process will refresh the system closing some of the processes to determine if it can detect the SD card. There is a  possibility that this is a software issue or minor system crash especially after a software update. To force reboot your device, simply press and hold your device’s Power key and Volume Up key for several seconds.

Step 2: Clear System Cache Partition

If your device was recently updated it’s software, that might be the cause. There are times that after the update it causes issues to your device rather than fixing. Some the of the temporary old are now irrelevant and it cause conflict to the new one, so, it must be manually cleared through Recovery mode. Don’t worry, it won’t delete any important files in your device.

Here’s how to run in Recovery mode:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Step 3: Remove Your SD Card And Reinsert

After performing clearing the system cache partition and the problem still occurs, then proceed and remove your SD card from the slot. Try to double check if the SD card is properly inserted and clear from any materials that cause connection problem, you can clean it and reinsert it back. The regular cleaning of it’s connectors is recommended to avoid connection issues, if there’s corrosion, it won’t conduct electricity normally.

Step 4: Make A Backup Of Your Files To Your Computer/Laptop Then Format SD card

As you mentioned, your computer and your Samsung Galaxy S5 was able to read your SD card, then we recommend to make a backup of your files or simply copy and paste to your computer. Then, reformat your SD card using your PC to have a fresh start, your Samsung Galaxy S7 Edge might be able read it after the process. If so, then simply restore your backup back to your SD card.

Step 5: Use Another SD Card Or Buy A New One

If the issue still remained after the format, what you can do next is to try another SD card if one is available. This is only to find out if the device can detect it or recognized other SD card, because you have to make sure that your device is not experiencing a hardware issue, if so, then this troubleshooting steps will be useless.

Step 6: Factory Reset Your Device

This step is mostly the last resort to resolve any issues before bringing the device to a tech. But, performing this procedure will clear your device internal storage and restore your device back to manufacturer’s default setting. I recommend to backup all your files first before you proceed.

Here’s how to do it:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Now, if ever this issue still occurs after the factory reset. Bring your device to the nearest Samsung service center in your area, it must be the SD card slot of your device has problems. You have to replace your device if they can exchange it.

  1. I’ve done all the suggestions above and none worked.
    What did work and has to be done every time I restart the device:
    go to settings…lock screen and security…encrypt sd card….encrypt.
    You do not have to wait for the procedure to finish. Just that action recognizes the card for all apps.

  2. When all of this failed, I used my laptop to improperly format a 128 GB micro SD to NTFS. When I re-inserted it into the phone it actually detected it and reformatted the disk. This was occurring after the damn thing would not detect three different SD cards. Hope this suggestion helps someone.

  3. I swapped my 16Gb card for a 32Gb card. My edge could not detect the new card. None of the above worked. I have Nougat on my S7. But i managed to use an old trick. The card was not encryptet as it was new but I still was able to chooce decrypt card. As soom as i pressed decrypt the card popped up in the taskbar with a question to transfer files. I aborted the decrypt and the card is still working.
