Screen keeps turning on with each notification

[Coop1979]

I might be missing something in the settings, but my screen keeps turning on for notifications. I didn't notice it doing that before the 4.2.1 upgrade earlier today.

Anyone else seeing this? I know my Note has this annoying behavior for text messages, but I've never seen it in a Nexus device.

See the little marks for Screen on? That's where the Nexus was turning in for 30 seconds for the notification.

The app DeskSMS caused this until a recent update. If you have it installed, update it and that should fix the problem. If you don't have DeskSMS, it's probably some other app that you've installed.

Didn't happen to me with 4.2 and doesn't happen with 4.2.1 either.

Look for a bad app as the root cause.

Apps can turn the screen on by using wakelocks.
Try to check for active wakelocks by using this app:

"Full wakelock" option shows the app which have an access to lighten the screen
