Thought I'd read somewhere about amoled having screen burn issues. Anyone have any tips on this for the Nexus? I woke up this morning to my screen being on (so it came on sometime between 2am and 7am) while on the charger. I shut it off after putting it on since I don't have a dock yet (the alarm clock app I'll use does have some sort of anti-screenburn algorithm) but it turned itself on randomly for some reason and was at the lock screen.
