I hope I'm posting in the right community, and that someone can help me out.

For the past couple days, my Samsung Galaxy S22 phone has started playing the default Verizon notification sound about once per day. I haven't nailed down the exact time, but it seems to happen in the morning.

The weird part(s)? My phone is on vibrate, and no notification seems to correspond to it. My phone is sitting on the desk, and I hear the sound, so I check my notifications, but nothing new shows up. I check my Notification Log app, and it doesn't show any new notifications. I check Settings > Notifications > Advanced Settings > Notification History, and it doesn't show anything either.

Today, I've changed my default notification ringtone to see if the new sound is triggered the next time. I'll update if/when that happens.

I'm a little concerned that the unexpected behavior could be malware or something, but I'm hoping something is just bugged.

Additional info that could be relevant: a couple months ago, I had to install the Libre Free app, and it was constantly making notification sounds, despite my phone being on vibrate. The unattributed notification sounds didn't start until after I stopped using the Libre app. I haven't uninstalled it yet, but I'm definitely considering it as part of my troubleshooting.

Ideally, I'd like to get to the bottom of this without a major reset of my phone. Does anyone have any tips/ideas?

Thank you so much!

It happened again this morning, and I was finally able to track it down with Nice Catch.

I had mentioned the Libre app in the post because it was the only app I had whose notifications would make noise while on vibrate. I thought I had disabled notifications, but it's clearly still doing something in the background.

I guess it's gotta go.

Awesome! I'm glad it was useful for you. ๐Ÿ˜Š

Before you ditch that app... If it's FOSS, have you considered filing a bug report to the developer? They may be unaware and find your feedback useful in fixing it for their users. That screenshot will probably help, too.
