I have a Galaxy SIII on AT&T network. My gallery icon has disappeared, and my camera will not work. It force closes when I try and open it. I've looked up and down the forums trying to find someone with a similar problem. The Gallery icon isn't hidden, its just gone. All my pictures are gone with it. Does anyone know a fix for this, or can I just download a new gallery app for my camera to start working again? Any help would be much appreciated.
