I just wanted to post this in case someone can offer a solution before I take it in for repair. My camera hasn't been working for awhile now. Whenever I open any application that would use the camera (stock, 360, barcode scanner etc.) It lingers on a black screen then eventually backs out and either says nothing, or gives an error message saying it couldn't be opened. I've been having some issues with other programs force closing occasionally (most notably tunewiki). So I have no idea what it could be. I decided to do a hard reset to see what would happen, and its all still the same except now when I open a camera application it stays on the black screen like before and after a few minutes says tap to active camera. When I do that it waits again, then just exits to home screen.
