Re: htc one not waking up on alarm
Do you just want the screen to turn on when the alarm goes off? I'm not sure why it wouldn't unless you have a security lock on the phone and you are not checking it fast enough, or your screen on time is set to a short interval and again you are not checking it fast enough. It could be possible that an app is preventing it from waking the screen. On my One from Big Red I don't have control over my power saver functions however I could see power saver not waking the screen for an alarm or some similar app. I don't see anything in my display settings that would prevent the screen waking however other carriers have a few different options and you may want to check for anything that is unchecked about waking the screen under Displays, gestures and buttons.
