Galaxy S8 Or Galaxy S8 Plus MicroSD Became Corrupted (Solution)

The microSD card is an extremely valuable asset of Galaxy S8 and S8 Plus. Samsung made the mistake once of pulling it off and users weren’t too happy about it. Now that it corrected the mistake with the latest flagships, people started to use microSD cards on their devices with a lot of enthusiasm.

After all, it allows you to store all kinds of photos, videos, and other personal files without worrying that you don’t have enough space or that your phone would start moving slowly because of that.

Needless to say, you really shouldn’t let the guard off and assume that just because you have your data on the microSD there is no need to do any kind of backups. Galaxy S8 users often complain about getting a message that the microSD card is corrupted.

We can only imagine your heart stopping for a while, at the thought that the card may be corrupted and you might have lost everything on it. Here’s the good news: many other users reported that after restarting their smartphones for several times in a row, the error disappeared and they were able to access the data stored on the card.

Simply put, if you see this message, there is still hope! Backup everything as fast as you can and you may be lucky. Nevertheless, if the microSD of your Samsung Galaxy S8 is officially corrupted, we suggest you try the following fixes:


Use a third-party app to monitor the device’s temperature

It is well-known that some microSD cards, like the ones from SanDisk, may stop working properly when the smartphone reaches a certain temperature. To check if this is the cause, you can download the TempMonitor or any other preferred third-party app and monitor the temperature of the device whenever you experience microSD reading problems.


Wipe cache partition and observe the smartphone for a few days

Wiping the cache was proved to work with many users, though, just like with the first method, it will imply closely monitoring what happens on your smartphone after you perform the action.


To wipe the cache partition on Samsung Galaxy S8 and Galaxy S8 Plus:

  1. Turn off the phone;
  2. Hold the Home and the Volume Up keys simultaneously;
  3. Then hold the Power key together with the other two;
  4. Release the Power button when the phone vibrates;
  5. Release the other two buttons when the Android logo shows;
  6. Now that you’ve accessed the Recovery Mode, you can navigate with the Volume Down key and initiate some commands with the Power key;
  7. You will have to highlight the Wipe Cache Partition option and press the Power button;
  8. Highlight the Yes option, for confirmation, and press the Power button again to get it started;
  9. When it finishes this process, reboot the device using the same two keys.


With the cache partition completely wiped, see if you can now access the microSD on your Samsung Galaxy S8. If not, you have one last thing to try…


Perform a factory reset as a final option

The factory reset is designed to bring the smartphone to its factory settings. Back up all your data, initiate the factory reset, and when the device restarts reformat the microSD right from the phone. This should fix the erratic behavior of the card for good!
