Unexplained regular alarm, what could it be?

[AC Question]

Unexplained regular alarm

For several days now my Android phone (FairPhone 1) beeps for about 30 seconds at 09:19. It's not the Clock app. What else might that be?

when it beeps does anything appear on the screen / notification panel?

I posted the original Q. No, no notification and nothing appears on the screen.

Hi and welcome to Android Central this beep that it makes, do you hear it at any other point in the day, i.e. is it a message tone or something like that? can you also dismiss it when it starts beeping? how long has it been going on for? and finally have you tried just turning your phone on and off and seeing if that helps?

It's not like the alarm from the clock app. Just a faint beep-beep for 30 seconds or so. Never noticed at any other time of day. Now or the last 4 days. I'll try the Bill Gates method, as you suggest.

Well, the spook is still there after a reboot. Always exactly at 09:19

I'll ask around and see if anyone has any input

Try Safe Mode.

Hi and welcome to Android Central! Try booting into safe mode and see if it continues. If it doesn't do it while in safe mode, it's a third party app that you have downloaded causing the issue. If it still does it in safe mode, it's in the factory system files.

Try that and we can go from there with your results.

Well, I booted in Safe mode (I'm afraid the Samsung Galaxy S4 instructions don't apply for a FairPhone 1, but I discovered how to do it) and the alarm again went off this morning – 20 seconds, very faint, at 09:19. So, according to dumpedduce it's in the factory system files. What's the next step?
