Twice in the last week now I have come to my phone pressed the power button to wake up my phone and nothing happens. Both times I have had to do a hardware restart with power and volume up pressed. I know the phone was still on because on the second occasion the notification LED was not flashing. My alarm never went off. I am fortunate that after the first time I questioned the reliability of the N4 and set my N7 as a second alarm. Has anyone else had this issue? Fingers crossed 4.2.2 is real and it has fixes for this stuff!!! *Additional Note* It has happened after it has been fully charged so first thing in the morning. Probably not an alarm as it happened on Saturday first and there was no alarm set.
