Regarding the Galaxy S9 line, on the whole, it’s currently in its 30th month post-release. The aforementioned jump to One UI 2.1 based on Android 10 should be the final major operating system refresh for the 2018 flagships. By this time next year, the Galaxy S9 and Galaxy S9+, note 9 are likely to be moved from Samsung’s fastest development track for monthly releases to one revised on a quarterly basis. Samsung began winding down firmware development on their direct predecessors two months ago as well.
