Google poaches one of Samsung's best always-on display features for Android Pie -
For its flagship lines, Samsung introduced wallpapers to the Always-on Display (AoD) feature that lets pertinent info stay on the AMOLED screen at all times, even when the phone is locked. It's an awesome option, as it lets users simply glance at the screen for the time, date, or notification info, instead of having to grab and unlock the phone each time, but is a bit of a battery drain.
