returning my phone.
turns out there's a rattle from the camera area which can be replicated when shaking the phone OR when tapping the top right section of the screen. Absolutely horrible - spoke to Apple who confirmed this wasn't right.
Spoke to O2 as I've only had my 256GB 7 Plus for 6 days and they are replacing it with a brand new handset on Thursday. Well done O2. I was dreading the fact they'd be out of stock as I visited the Apple store in Milton Keynes on Saturday to buy the black dock to match and the apple guy seemed surprised to see a black 7 Plus, asked me what size memory and was admiring the phone.
PS. get to keep the box and all the accessories from the first iPhone too
