Windows Central Question
My Lumia 520 phone was okay until a couple of days earlier. Now I can't see pictures I've taken or videos I've recorded last few days. I put my SD card on computer and tried to play the recent videos but it says the video format is usdf (can't play) and something similar error for pictures. I can play older videos or look at older pictures. I don't know what happened. I didn't change any settings. My phone's camera roll shows the recent pictures I took but they're just plain dark gray and when I open it says "Can't get picture. Try again later" for photos. I took many videos to test this, some of them just disappeared. Please help.
