Hello, i own an LG G FLEX 2 for over a year now, and today, about 30 minutes ago i was using the camera on whatsapp just fine. now, 30 minutes later my camera is not working, when i open the camera on whatsapp, its just grey screen, when i open camera app, its just black screen and eventually just closes the camera and says its not responding. i tried restarting phone, turning off for some time, tried cleaning camera cache, nothing seems to work. then i tried turning on flashlight, but it says that you cant use camera while other app is using it. i havent installed new apps for month + for sure. ive tried everything, anyone have any suggestions?
