I did look my N800 screen more closely, especially corners/edges. It looks like that there would be edges at corners.. Its possible that there is already screen protection film at my N800. But when I did get device I did pull one protection off screen. One thing is sure, i am not trying to claw it off if there is one.. Dont understand why anyone should, only maybe after years if it goes bad. If there is film it would explain those air bubbles. Anyway I leave my screen alone it is good now.
