Few days back, I was searching for my files in my file manager and noticed that my sd card wasn't recognized by my phone. I tried to remove it and inserted it again and nothing happened. I tried lots of applications to fix it but there's no result. It doesn't say anything like "the sd card is damaged" nor "sd card is unexpectedly removed". Please help me to fix it without deleting all my files. I have a lot of important files in there. Pls help!
