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?

Sorry, this is going to come across as a newbie rant... mostly because I just switched a few months ago. I'm not completely unfamiliar with Linux. I had to use Unix in college for some projects. I've dual-booted with Windows before. I use a Mac at work. I'm reasonably comfortable in the console, though I'm certainly no expert. I feel like what I'm about to talk about shouldn't be so confusing/unintuitive.

I'm running Kubuntu on an older laptop. I have a burnable DVD that may or may not be blank. The disc is old, scratched, and unlabeled, but I would like to see if anything is on it.

I press the eject button on my laptop's disc drive. The tray comes out. I insert the disc and close the tray. The system gets busy trying to read the disc, but eventually stops spinning. Nothing pops up. Dolphin doesn't show my disc drive in the "Devices" panel, or that there's anything in the drive. VLC says it can't read the disc.

Ok, fine. The disc is probably either empty, or it's too scratched to read and needs to be trashed, so I would like to remove it from my system. I push the eject button again, and... nothing happens. It's the same button I used to open the tray to insert the disc, but now it's unresponsive. I open Dolphin and confirm that it doesn't show that I even have a disc drive in the "Devices" panel (presumably because nothing's in it). I open the "Discs and Devices" section in the Notification tray, and the most I can get it to show is my hard drive. It's like my computer doesn't believe the DVD drive exists.

So, what do I have to do? I can open MakeMKV, and it has an Eject button that opens the tray. I'm sure plenty of other software has similar functionality. I can also open the terminal and type "eject", and the tray pops right open. Clearly, my system knows that there's a DVD drive, and it has the ability to open the tray.

Why doesn't the eject button work? Why doesn't Dolphin just always show the DVD drive? Why do I have to google "How to eject a dvd kubuntu"? What am I missing?
