I'm not sure if I'm the only one who hears this~ but occasionally during the use of your phone. Usually coming off of unlock and turning the screen on, or opening an app... do any of you hear the sound of the shutter going on and off? You know, the tiny little pitch whine or pop that occurs when you take a picture? I hear it happening occasionally, just out of the blue. I can even feel it a bit in my hand if I pay attention. It's subtle, it doesn't make any apps open or slow it down, but I can clearly hear the camera "activating".
