If the device failed to read from the microSD card, and this error occurred first time, Reboot the device and see if it can detect and read the card during boot up.
System crashes can also cause the device unable to read the external storage. So, there may be a firmware crash issue and not necessarily an SD card problem.

Step 2: Unmount the SD card, clean its interface, then remount

If the problem exist after Reboot, then remove the microSD card and use a dry, clean cloth and wipe its interface or receptors. It is possible that they get corroded and won’t conduct properly. As a result, the phone may not be able to read from the card.
The fact is even the simple unmounting and remounting will force the device to detect the external storage and take time to read from it. So, this step is really very helpful after the Reboot.

Step 3: Let your computer / laptop read the SD card

If the device is still unable to read the microSD card, then check if it’s a problem with the card or the device and there’s no other way to do that than to let the laptop or computer read the card.

Computers can easily read removable devices even those that have issues. So, to know if the problem is the card or the phone, let the laptop or computer check it for you.

If the card is corrupt and the computer can’t read from it, check immediately   whether to reformat it or not. However, if it can read and access files from it, then have a back up of these .

Once you’ve a back up your files, Reformat the card using FAT32 and remount it to the device. If the phone still refuses to read from it, then there can be a problem with it.

Now, to check if the problem is in the phone, use a different SD card about which you are sure that it does not have error. Mount it on your phone and if it won’t read from it, then check again there’s nothing blocking the receptors inside.

Step 4: Send the phone to repair or buy a new SD card

If the phone works fine with another SD card, it means the issue was in the card. This problem can be resolve by replacing it with another SD card.
On the other hand, if the phone cannot read from another SD cards too, then the issue might be with the phone.
At this stage Reset the phone to check the possibility that it’s a firmware issue.
