Screen does not totally refresh when passing pages
I don't know what I did to my PB360, byt I left it in my car (with its cover on) and it was very cold outside.
When I turned it on again, the top right (portrait view) area of the screen had a frozen part of another page, like a "leftover", which looks like a page had been torned from a pad, but part of the page had remained on the pad.
I think that if I reset the device or flash the firmware again will probably fix this, but How did it get there? Anybody had this problem before? Is what I think of doing the correct procedure for this? How do we avoid this from happening (is it because of the cold?)
