Samsung becomes secret Santa for its users. And it does that by bringing in a little surprise for its Galaxy S9 and Galaxy S9+ owners.The news has it that the stable Android Pie update would be rolling out to the Galaxy S9 and S9+ in Germany. You are right, Samsung had said the Galaxy S9 and Galaxy Note 9 Android Pie release would be in January, but perhaps there's a little tweak in the plan. And the best part is the update has been released for those on Android Oreo and not just beta testers.
The software version for the final update is G960FXXU2CRLI and G965FXXU2CRLI for the Galaxy S9 and Galaxy S9+ respectively.
So if you’re a Galaxy S9 or S9+ user in Germany, do check for the update from the Settings » Software update menu by tapping the Download updates manually option (Download and install for those on the Android Pie beta).
Happy Upgrading to you!
