I have tried turning to all different shutter sounds, off and on, all volumes on the phone are up. The phone just doesn't make a tone anymore when taking a photo. It also has stopped making the tone when you start and stop taking a video. I have gone to settings, applications, manage apps, all, camera, and cleared the data in hopes that would fix it. Nothing. I really don't want to factory reset it. Anyone have any ideas? Any way to re-download this camera app?
