I tried to show a friend a photo but every time I opened my gallery, it force closed, so naturally I restarted the phone. After restarting, I went into my gallery and nothing was there. Then I went to Google Play and all my music was gone. For both cases, it's ONLY files that were on the SD Card that disappeared; about 200 songs and 80 photos that were saved to the device stayed in their respective apps. I went into "My Files" and nothing was there so I freaked out because I have about 900 photos and 1000 songs saved to my SD Card and that's a hell of a lot to lose and thought that, somehow, restarting the phone (which I have done before without incident) wiped my SD Card. So I took the card out and put it in my friend's phone (she has an S7) and every single file was there in "My Files", and in MY phone's settings, it says that there's still 14.87GB taken up, so obviously everything's still there, I just can't see them on my phone. I can see them on my friends, though. How do I fix this??????
