iPhone XS Lock sound sometimes quiet, sometimes loud
About a week ago I switched over from Android to Apple and purchased the iPhone XS.
One quirk that I have noticed with this phone, and I have not been able to consistently replicate it, is the lock sound mysteriously gets quieter/louder on a whim.
I am not sure what triggers this, but sometimes it will be loud, and other times it will be quiet.
I have tried turning off attention aware features, but that did not seem to be it.
Has anyone else experienced this? And been able to track down what causes it?
Kinda sounds like this:
