Ok I recently pulled my old 9700 from the bedside drawer after a few months. I've been trying out different OS' and have found the same problem with all 3 I've tried recently. I've used os 5 (.862) and os 6 (.615 and .723) my screen randomly goes white and will stay that way until I press the screen lock button 2x (to lock it then unlock). Does anybody know of a possible cause for this? I really want to continue using the phone but this is getting annoying. (By the end of the day,when left at idle for only about 5 seconds, the screen would go white) last night I did a wipe and clean install if my os (currently 5.0.0.862) to no avail. So I'm at a loss. Any help would be much appreciated.
