Android Pie has been out for a few months now and Samsung is coming along with their update, which is called Samsung Experience 10. Every update that is leaked comes with more and more new features. In the latest update for the Samsung Galaxy S9 (CRJB), Samsung has added a new feature to the Always-on Display making it act like the Pixel "ambient display." When you double tap the screen while locked, it will show the Always-on Display for 30 seconds.
