Hi, my new iPad is only a week and a half old. But I noticed that when I tap the back casing in the top right (camera side) I hear a slightly metallic sound as if something is loose inside. I'm very nervous and worried about this and obviously whether it's normal or not I ought to not be tapping it. But I can't help but wonder if it's ok.
So is this a recognised thing and/or do your iPads do this?
