Uncategorized
Only 7 days after their second December update, BUL6, Samsung has begun rolling out their 5th Android 12 release 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/BUL1/BUL6 builds on the international devices.

Changelog

  • Device security improved
  • Bugfixes
  • After upgrading you will not be able to downgrade to the old software because of updates to the security policy.

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.
