Although Samsung had to work on its custom interface before unleashing Android 8.0 Oreo for the Galaxy S8 and the Galaxy S8+, it took them quite a while to do it. The Android Oreo-based firmware for the company's flagships has been in beta testing since last autumn (early November, to be more precise), but now the final release is rolling out.
According to SamMobile, the Android Oreo firmware with Samsung Experience 9.0 on top is rolling out in Germany. The first ones to get it, just as Samsung promised, are the beta testers. Obviously, the size of the update is also smaller for them when compared to the files that will be heading for regular users still stuck with Android Nougat and Samsung Experience 8.x. Fortunately, they will not have to wait for much longer, since the update should begin to reach them about 24 hours after the beta testers.
As revealed by the screenshots that already surfaced online, the Samsung Experience 9.0 update comes with the February 2018 security patch included. Obviously, the list of changes consists of the regular Oreo goodies, next to the personal touches delivered by Samsung's custom UI that was once known as TouchWiz and now goes by as Samsung Experience. Sadly, there is no support for Project Treble.
