Samsung is rolling out a new software update for the Galaxy S9 and Galaxy S9+ in Germany. The new update doesn't come with the March security patch or any new features or improvements. The changelog is the same as the one for the last update, so we can expect some minor improvements under the hood that won't make a noticeable difference for users.
Not that those improvements don't matter, as Android Pie has been out for only two months at this point for Samsung's 2018 flagships, so there will be bugs to fix and instabilities to iron out (such as poor battery life that some folks are facing). The newest update weighs 90 MB and comes with software version G960FXXU2CSB9 and G965FXXU2CSB9. It's rolling out over the air at the moment, and you should be able to download it from the Settings » Software update menu on your S9 or S9+ by tapping Download updates manually.
We also have the firmware for the update available in our database (Galaxy S9 | Galaxy S9+), which you can use to manually get on the latest software version. Do let us know should you notice anything different after installing the update by leaving a comment. We'll do the same and update this story if we find something of note.
