If your Android phone is having trouble reading or writing to its SD card, there are a few things you can do to try and fix the problem. First, make sure that the SD card is properly formatted. This can be done by using a computer or an SD card reader, depending on your device. If the card is not properly formatted, Android may not be able to read or write to it. If the card is properly formatted and still doesn’t work, you may need to reformat the SD card again. To do this, go into Settings on your phone and select Storage. From here, tap on the option for “Format” and choose “SD Card.” Make sure that “Erase everything” is unchecked before clicking OK. This will erase all of your data on the SD card and format it anew. ..
