Bringing this thread back because I also have burn in problems and didn't want to make a new thread.
Since I was using the early versions of NoLed, my phone used to sit at night plugged in, and get notifications. In the early version you couldn't time it out, so the phone would sit all night with the "battery fully charged" box in the middle of a black screen. I didn't think OLED screens would have problems, but its burned in.
Is there any thing you can do to work it out? (similar to the programs that can sometimes un-stick a pixel on an LCD monitor)
