A lovely "feature" that 16.2 adds is not being able to figure out what hardware I have, and think I don't have an "official" camera. So now, I have an alert on settings I can't get rid of, and no way to get it iOS to pull its head out of it's stamen and check again. No problem with this prior to 16.2, and no, I didn't have any parts replaced. It is an AppleCare replacement phone though, so I half wonder if they gave me a hobbled together used FrankeniPhone.
