One UI 2.1 is the latest iteration of Samsung's Android 10-based skin that debuted on the Galaxy Z Flip and the Galaxy S20 series of smartphones. Samsung later rolled out the One UI 2.1 update to the Galaxy S10, Galaxy Note 10, Galaxy Fold, Galaxy S10 Lite, Galaxy Note 10 Lite, and the Galaxy Tab S6. Although Samsung has yet to officially roll out the update to the Galaxy Note 9 or Galaxy S9, owners of these devices can enjoy all the goodness of One UI 2.1 thanks to the work of XDA Recognized Developer AlexisXDA.

The developer has ported One UI 2.1 to the international Exynos versions of the Galaxy S9, Galaxy S9+, and Galaxy Note 9 since those models can be bootloader unlocked. The developer decided to incorporate a slew of Galaxy S20-specific features (like Pro mode in video recording) and the whole Good Lock 2020 suite in the packages. Best of all, the TWRP-flashable zips come with an integrated AROMA installer, allowing end-users the freedom to customize each and every aspect of the installation.

There have been conflicting reports about whether Samsung will officially bring One UI 2.1 to the Galaxy S9 or Galaxy Note 9. A Korean Samsung community moderator stated the two phones will get the update, but we haven't heard the same from the company through any of their official channels yet. For reference, the Galaxy S9 debuted with Samsung Experience 9.0 based on Android 8.0 Oreo while the Galaxy Note 9 debuted with Samsung Experience 9.5 based on Android 8.1 Oreo. Thus, when both the Galaxy S9 and Galaxy Note 9 received One UI 2.0 based on Android 10, they both secured their second major Android OS update, so there's no guarantee they'll get further major software updates.
