The Alarm goes of at 8:00 PM every night on my phone but I have no alarms set for 8:00 PM. I had two Alarms set for 8:00 AM but they are both turned off. Contana is no help and I'm not finding any similar issues on Google. I just deleted my 8:00 AM alarms after it went off again today at 8:00 PM. The time is set correctly. I 'll wait until tomorrow to see if deleting all alarms worked.
