So I took the plunge and traded in my Z2 for the 930. Waiting for my nano sim to be delivered so haven't really used it much apart from setting up the phone and updating the apps over wifi which took 20-30 mins. Just to confirm it did get warm around the base of the phone but not hot to the point where it was unbearable to hot as other forum members have mentioned. The phone is charging now and became quite hot during the first 30 mins but it's cold as ice now. Haven't noticed any purple tinting on the screen. Blacks are black. The only time I have seen the black background turn grey is when I select filter my contact list under people hub. But the color seems consistent with my L900 which I am using now as a backup phone.
