Comment 13 for bug 1291455

The latest instance of this was my phone locked after too many unlock attempts while in my pocket making it quite inconvenient to take a picture.
Contrary to my comment #6 I can trigger touch events through lightweight fabric like pocket lining.
I disagree with point 1 in comment #9, If you can see the screen the proximity sensor will be disengaged. If you can't it should prevent the screen from coming on. That is:
Event happens - proximity is true - screen off
user takes phone from pocket - proximity now false - screen comes on unless timeout period has passed

I think all the issues with inadvertent touches are resolved by fixing this to keep the screen off until proximity is not detected.

Also see bug #1426115 to shorten the time the screen is on when triggered by an event
