My micro SD card can't be read for no reason (though I conclude that it's because I dropped my phone). My phone doesn't show files stored in the micro SD card. And the phone shows that I have a blank micro SD card and suggests that the micro SD card should be formatted. I clicked the format button but it went on again displaying that I have a blank micro SD card. The computer doesn't read it too. Is there a way to recover files from my micro SD card that can't be read? Or should I format it first, then have the files recovered?
