[04/JUN/21] AUF2 Global, Exynos, JUNE Android Security patch + camera update

A sense of deja-vu is emerging with these Samsung global, Exynos, releases.

In April, Samsung had a partial roll-out of build AUDA only to replace it 10 days later with a new worldwide release, AUE1, on an identical change list. The same thing has happened with the AUE8 build, released a week ago with the June Android Security patch, being replaced by this AUF2 build, also with an identical change list.

This latest update is the 12th for the Global, Exynos, S21 series and is currently being rolled out by Samsung.

This update is for camera, general bugfixes and June security patch.

Initially, as always, this is rolling 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 G99*BXXU3AUE1/G99*BXXU3AUE8 May 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.


  • Performance of camera has been improved
