It has occurred to me that it could be as simple as a battery issue. It heats up, distorts the screen, etc. If they had a different battery (they request that you send it without the battery or other accessories) and they put in a nice shiny new battery, the problem goes away (after being cooled for X period of time).

When I had turned it off last night, then this morning turned it back on the bright spot wasn't as bright. So this could be a sound theory.

I think next time I'll just test it with the battery out, just use my old phone for a day or two and see if I can boot it up and the spot is gone.

As a side note, where is a good place to order a second battery?
