When u try to move photos from one folder to another, it shows an exclamation on a Grey screen and even says new on the folder even tho the picture is greyed out. I saw someone say that you go to settings > developer options > applications > do not keep activities and that worked for someone else but I don't have the applications option after I select developer options. Please help. It's the most annoying thing to lose pictures of loved ones. Thanks in advance!
