Hey everyone, I've been having some problems with my camera/pictures. All of a sudden, my pictures appear very grainy/pixilized (I can't even make out people's faces in the pictures). And some pictures are appearing as completely black. Also, everytime I take a picture, I can never find them in the camera roll unless I go to photos-->camera roll. I've tried turning my phone on and off multiple times, and doing a hard reset but nothing seems to help. Has anyone had any similar problems? Thanks.
