Alright…I’m working on a theory here (and it’s just a theory based on my personal experiences and very little testing), but…
…for me, it never happens during the day. Not sure why that is.
And, in the last two hours, I’ve been sitting in a semi-dark room and the AOD has turned itself off multiple times…but I just noticed that, as of my limited recent testing, it only turns off when I have the full screen media wallpaper active (aka the thing where you tap an album cover on the Lock Screen media player and it makes the album art the wallpaper).
When the media wallpaper is active, the AOD turns off after a minute or two of the phone being locked (in my semi-dark room). When the full screen media wallpaper isn’t active, the AOD doesn’t seem to turn off (in my semi-dark room).
Can anyone confirm or deny this theory?
