So long as your phone is in vibrate or silent mode, you will not hear the shutter sound. (I just ran a series of tests, changing sound settings.) That's the only way I can find to silence the camera, so that should be the only way to unsilence the camera.The camera makes no sound when taking a photo and I am not able to find a setting for that. Can anyone tell me how or if you can set it?
