I'm having trouble with viewing my pics. Sometimes when I view through my pics and videos they disappear from the albums or in their place is a triangle with am exclamation point in the center of it. Now I have found that if I restart my phone all my pics and vids show back up for a while then it does it all over again. Anybody know why it does this or even a way to permanently fix it? Has anyone else had this problem? I would like to take it to the store and see if they could fix it but the hours I work I can't.
