Display unlocks frequently without interaction

That might not be necessary. So far I did not observe any more wake ups.
So it might very well be the combination of the accelerometer-bug and a weird behavior in lightswitch (0.09) which ignores my settings.

I would observe it for a few more days before calling this fixed, but there's hope that's it.

However, I do use Light switch widget to unlock on tap (right tap side).

Thanks for the hint, I would never have thought about blaming this widget.
