Ringtone/alert volume adjustment is backwards
Recently when I turn up the volume on my phone, all ringtones, notifications, and even keyboard haptics get quieter. When I turn the volume down, these sounds all get louder. For some reason music, videos and all sounds that don’t have to do with alerts are unaffected. Basically the volume buttons work backwards or in the opposite direction of the way they should.
The problem started a few weeks ago. Is this an iOS 16 bug, a hardware issue, or something that I can fix in settings?
