So I just got a brand new Jet Black iPhone 7 and if I tap it near the earpiece or shake the phone in my hand it makes a rattling sound. I don't recall ever experiencing this with previous iPhone but I thought I'd check here first and make sure I'm not crazy. So does your iPhone 7 rattle when you shake it, or when you tap near the earpiece speaker? What could it be? Should I take it to the Apple Store or is this normal? Do you think they'll replace it?
