My camera isn't working so far. I tried camera and was working great when mobile arrived. On another day I wanted to photo something, but application had black screen and camera wasn't responding. I didn't used camera during all time. I tried restart my phone, it helped if I open camera first until I opened another app, But just for maybe 3-4 times. Now I tried factory reset. But my camera is totally dead and I can't open it anymore... Any ideas how to solve it ?
