The Samsung Galaxy S10, S10+, S10e, and S10 5G are now getting One UI 4.1 based on Android 12. The three phones originally launched in early 2019 with Android 9 and the original One UI. The Samsung Galaxy Note10 and Note10+ were released in mid-2019, also with Android 9 and improved One UI 1.5. Last December, the S10 series and Note10 series received Android 12 with One UI 4.0.
The Note update takes up quite a lot of space, 1049MB, and makes changes to several apps from Samsung. The update has firmware version N976BXXU7HVC6 and includes the March 1st security patch. The S10 updates also include the March patch.
As for newer models, Galaxy Note20 models started getting One UI 4.1 as early as last week.
