screw bending, thats a mechanic failure... more intresting is that new iOS 8 update got trouble to make a call
seriously?? main phone function got trouble?? i would understand all these bigger and smaller fails, but this is ridiculus fail
also one of worst things , it still got glass screen, so one or few drops on ground... and you'r done
btw, is it possible to quickly replace battery in iphone 6 now, or still needs specialised work?
