I have the notification and WiFi issues as well, though I just changed the sleep policy, so I will have to test it and see if it resolves the problem.
This morning my alarms did not function properly, the alarm went off (phone vibrated) but not audible alarm. I confirmed that they were set correctly and tested with newly set alarms. Reboot fixed.
I have also been having problems with Google Music/Pandora and the Music app. If I am listening to Google Music/Pandora and then "quit" the program (using menu button) the program will close, but Music then opens and starts playing? I remember that there was an setting to pause/play when headphones were connected or disconnected in older software versions, but I cant find that setting anymore. Anyone else seeing this issue?
