[UPDATE] Now available for the U.K.


Only 11 days after the initial release of stock Android 12, Samsung have begun rolling out their second official stock update of Android 12, One UI 4, for the S21 series of international devices.

With a Build date of just 3 days ago, it would seem that this is a bugfix update.

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

The Galaxy S21 international 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*BXXU3BUK8build on the international devices.

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.
