What to do if the microSD card does not work on your mobile

24 mayo, 2021

To have a mobile with support for microSD cards gets you out of a lot of trouble. Although it is not exactly the same as the internal memory, it helps you to save your music, photos or even Netflix series.

The problem is that these microSD cards don’t always work properly. Sometimes they can stop working, showing empty on Android and asking you to format them to be able to use them. Today we’ll see What can you do if your mobile’s microSD card doesn’t work? correctly.

0. Check compatibility

We are going to review all the steps that you can carry out by level of ease, although a previous step that you should carry out is check compatibility. This only applies to new memory cards and not to cards that have stopped working, of course, because if they were incompatible they would not have worked from the first moment.

Manufacturers generally don’t bother much to indicate microSD card compatibility beyond the maximum capacity. You should be able to find this information and take it into account, as a higher capacity card will not work directly.

How to choose a microSD card for your mobile

1. Restart the mobile


Have you tried restarting the mobile? Before getting into more complex solutions, the easiest thing to do is try your luck rebooting. In my personal experience this has occasionally solved problems with microSD cards that had “disappeared”.

If your mobile recognizes the card when it returns from the restart, the good news is that probably nothing happens to it, but it is a software bug punctual. It’s frustrating if it happens to you randomly, but at least it’s quick to fix.

2. Take out and put the card back in


All my Android phones to date have supported microSD memory cards, and I admit with some regret that I have had problems with microSD cards in almost all of them. Restarting the mobile sometimes fixes it, but the most effective remedy is another: take out the microSD card and put it back in.

Don’t ask me the science behind it, because I don’t know it. It may be that there is dust on the connector, that it has moved slightly or just random, but this action usually brings your microSD card back to life. Just be careful not to lose it (Or your SIM!).

3. Try it on a PC

If all of the above has failed, Take out the microSD card from your mobile and test it on a PC. Be careful, because the most normal thing is that the PC card reader is for SD cards, so you need an adapter. And if your PC doesn’t have a card reader, you can get a USB reader for a few euros.

If you can see the content on the PC, then nothing is wrong with the card, and this is usually normal. Take the opportunity to move or delete a file, unplug it safely and try it again on your mobile. It is very likely that now it will work.

4. Format it from your mobile


If you don’t care much about the content on the microSD card or you have one recent backup of its content, another option is to format the card, or configure it, as some layers of Android call it. This is in fact the default option when the system detects the SD card as corrupted.

Just tap on the card and choose Format. Remember that the process is irreversible, so carry it out only when you are sure that the card details are not important and if all the previous methods have not worked.
