I just called Google. RMA is inbound. It just kind of sucks, this phone was solid. No light bleed, no dead pixels, etc. Except for a loose power button.
Anyway I think it is definately a hardware issue, as my phone has been getting crazy hot lately. I know it's supposed to get hot, but this phone was scorching...Might have fried something.
