Question Single unique sound at 23:31 every night on a Samsung phone

[Ekaterin]

My phone is sounding a single unique sound every night at exactly 23:31.

It's not low battery as it happens when it's on charge as well as when it isn't.

It's not an alarm, I've checked.

It's not a notification as nothing appears in the top of the screen.

It's happened on my Z Fold 4 and my S23 ultra.

What's going on

Welcome to AC!

Sounds like something 3rd party app

If you have any battery apps uninstall and see if it happens otherwise 3 minutes before that time out device in safe mode see if it will go off

Booted into safe mode. Waited. 23:31 - weird beeping sound as per usual.

Then look now at the default apps , notification reminders and such, its not coming from 3rd party apps .

Being as you are using a Samsung phone, nice catch from good lock might help.
