If I set an alarm for two hours from now, it will go off. I've tested this a few times.
But my morning alarms, at 6:07 and 6:13 am, just don't go off. I've been testing this for like a week now and I cant figure it out. Later in the day, maybe 3 or 4 hours later, the phone will alert me that I missed the alarm, even when my body clock wakes me up before the alarm and I lay awake watching my phone tick past the alarm time without it ever twitching or doing anything.
So far, I've tried:
- Deleting all alarms and recreating them
- Clearing the app cache and data, then rebooting
- Removing Duraspeed system app which I suspected of causing problems
- Toggling every setting and widget related to alarms and DND I can find
Here's my alarm setup:
Clock app settings:
Android sound settings:
Now, I suspected it was some battery thing killing the app, or DND preventing it from going off, but these settings all look correct to me:
And just now, its warned me about the missed alarm that I laid awake watching not go off:
Any ideas about what else to investigate, or what else to do? Should I just download and rely on a different alarm app or something?
One way to check is to make a new alarm for ten minutes earlier or later than the old alarm, and see if that one sounds. I have DND turn off half an hour before my alarm goes off, but it also is supposed to ignore the alarm altogether (not interfere with alarm settings/sounds).
You may also want to see if the alarm is sounding on the old phone (if you haven't already wiped it, sold it etc).
