After Upgrading to lollipop, pattern lock issue, after unlock again screen locks , very annoyinig
I know this is dumb... but are you using flip cover. I had similar problem with my oneplus one recently and in the oneplus one forums they say that this is caused by the magnet in the flip cover. When you fold it back it falsely triggers the locking mechanism it seems. Although i agree to this i don't know how it wakes after sometime!!
