Question Moto G Power 5G dings for for no reason

[oldtimer114]

I have a Moto G Power 5G running T-Mobile's version of Android 15. And occasionally it puts out a single loud Ding for no apparent reason. No new calls or texts. No software updates. I have alerts turned off. Battery has plenty of charge. I don't have a Google account and have never signed up to any app store and have gotten rid of all the bloatware that I can. But still I got the occasional ding. This is really annoying. Especially when it happens at 3 AM and is loud enough to wake me up. It's not unlike a cat demanding attention. Anybody got any ideas?

Is there a pattern to the sound? Is this a daily, weekly, monthly thing? Is the device setup to automatically update Android?

No. there is no pattern that I can figure out. It's just a single, loud ding. The same ding that it makes when I get a new text. But in this case there's no text. It happens very irregularly. Might go a month without it happening. Then it happens 3 times in one week. Although it does happen late, after midnight, more frequently than during the day or evening.
And no, I do not have anything set to automatically update. I don't allow my phone to do anything automatically.
I wonder it might have something to do with those Amber Alerts we have here in Texas. My old flip phone used to get a very loud voice message followed by a long text message every time anyone in the entire state reported a missing child to a local police dept. But I don't get those on this phone. I have the "Crisis Alerts" setting turned off.
