Samsung have begun rolling out the first official stock update of Android 12, One UI 4, for the S21 series of devices...

Initially, as always, this is a staged roll out to the non-carrier branded, stock Samsung CSC codes first.

The Galaxy S21 Global, Exynos, devices that will receive this update are...

  • S21 5G model SM-G991B
  • S21+ 5G model SM-G996B
  • S21 Ultra 5G model SM-G998B

This latest release replaces the previous G99*BXXU3ZUK1 / G99*BXXS3AUJ7 builds.

It is a FOTA, (Firmware Over The Air), update and you can check... Settings > Software update... to see if it is available for you. Alternatively, you can connect to the Samsung PC suite, Smart Switch and check via that.


Changelog (for  those coming from Beta)

Have updated post #1 to place a link in, "TOP TIP", on how to wipe the phone's Cache Partition and use Galaxy App Booster as this is considered best practice after a major update and can solve a lot of issues including lagging and apps foreclosing  without having to do a Factory Reset and wiping your device.

Really? It should come pre-installed with the Android 12 update. 

Try looking for Good Guardians in the Galaxy Store.
