iPhone is chiming randomly without notification.
My iPhone has been making weird chiming noises randomly throughout the day. They're unique sounds that I've never heard from my phone, and no notification comes up with it.
I've checked my settings, and I don't have any notifications turned on that would chime, but not have a banner or badge.
There are two different chimes: one sounds like a walkie-talkie beeping three times, and the other sounds like an actual bell.
What are these?
iPhone 7 Plus, iOS 14
