Hello guys. Got a little concerned about a rattling sond that occures when I tap my iPhone 6 on the back or on the top part of the screen. It seems to come from the camera. Is this some part of the camera optics which makes all iphone 6 rattle? Or is there some defect? It does not rattle when I shake the phone. It doesn't give much of a sense of quality when you hear the rattling sounds.. So i thought i'd hear with you guys. Does your iPhone 6 rattle when you tap on it?
