I found some major bug on my N950 when you have a password on the lockscreen with "no delay" selected.. sometimes i cant enter my password or swipe the screen away. if I enter the pass with the keyboard, the touchscreen doesnt wont somehow... I can't power off the phone either... (device still thinks that it's locked so it wont power off) I need to do hold down the power button for like 10 secs so it will turn off...
