iOS 13.3 iPhone Xs ringer volume changes itself
I recently upgraded my iPhone Xs to iOS 13.3 and the ringer keeps resetting itself to maximum volume. It's happened three times today alone. I'll turn the volume down using the buttons on the side of the phone like I normally do. The "ringer" status indicator drops down from the top of the screen confirming my input. I'll then lock the screen and set the phone aside for a period of time only to be startled by a notification at full blast. When I unlock the phone and use the side buttons to adjust the ringer again, the status indicator confirms the volume is at max.
There's no chance I'm accidentally pushing the side buttons here. The phone is definitely doing this on its own.
iPhone XS, iOS 13
