And it is confirmed, today I got the screen lockup again and managed to get out of it by the same method;1.) when the device stopped responding to touches, did double-push power button to lock it, then again double-push to get to the lockscreen pin entry. 2.) did the number entry with 2-finger-taps and was able to unlock the device, unfreezing lipstick Note; at least my device is prone to lipstick freeze after a phonecall, altough not every time, maybe one out of every 5 or so... Somehow dependant on what gestures I do after ending the call.
