Currently I don't use AOD, because it's useless, it can show only time (on my Zenfone 7 pro).
I suggest to add at least notification icons on Always on Display, to see the icons of applications, which have notifications.
There are a lot of other options, what to add on AOD, for example, charging status (like Samsung have), if you will add type of charging (slow/fast or voltage), that would be cool.
Any modification will be appreciated, because currently using AOD makes no sense, it's like 2mp camera without autofocus in old phones - you literally have a camera, but it's almost useless 🙂
