[07/DEC/21] BUL1 DECEMBER Security update rolling out

The updates just keep on coming.

Only 11 days after their bugfix update, BUKG, Samsung have begun rolling out their 3rd Android 12 release… the December Android Security patch for the S21 series of international devices.

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*BXXU3BUKG build 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.
