iPhone 5s 64gb, does anyone else's rattle and the top corner of the screen loose?

Hi all,

Just bought a 64gb iPhone 5S.

I have literally just inboxes it to find the top right hand corner of the screen can be pressed in ASIC not fitted correctly, and the power button rattling around. Is this the sort of quality I should expect from a £709 phone?

Moved to this from an iPhone 4S I had from launch which doesn't have any issues like this!

Cheers

Rob
