This latest update for the Galaxy S9/S9+ is based on Android 10 with Samsung’s One UI 2.0 skin sitting on top. So, you get to experience a heap of new features.

To begin with, Android 10 brings improved navigation gestures, which completely removes the navbar for that little extra screen real estate and delivers a more powerful navigation experience with swipes and pulls. It also comes with system-wide Dark Mode, something that S9 users are already accustomed to since One UI 1.0. The added benefit is that Android 10’s Dark Mode further extends to installed third-party apps as well.
