This phone is getting very warm, I wonder if it's the aluminum combined with the internal battery? I've never had such heat with the former plastic Lumia's I've owned the 810, 710 & 521. I will have to get a case for this to diminish the discomfort. Not happy about all this heat when charging and at other random times. It's also buggy sometimes suddenly I can't set my screen to Bing it was working prior. A few little other glitches here and there but hoping the kinks will get worked out. I think next time I'll stick with the full plastic body.
