One other observation I wanted to ask everyone that has an iPhone 7, is if you notice a little buzz or vibration when you tap the back of your phone near the top half where the camera is? I did some googling and apparently some people have this and it's because the camera is mounted with springs and magnets supposedly and it moves a little. It's not like the phone rattles or anything like that it's just when you tap it with your finger gently. Has anyone else tried that and noticed it?
