It looks as though Samsung has pulled the previous AUDA update for reasons known only to themselves at the moment. After a hesitant roll-out to 7 countries it has been dropped for this new release. A pity really as I found the AUDA firmware to be pretty good. The changelist for AUDA and the new AUE1 are identical, 21556388.

This latest update is the 10th for the Global, Exynos, S21 series and is currently being rolled out by Samsung.

This big 1.1GB update is for camera, general bugfixes and May 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*BXXU2AUC8/G99*BXXU3AUDA March/April 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.

Changelog

• 
  
  • Performance of camera has been improved
  • Enhanced QuickShare
  • The security of your device has been improved
  • After updating, you will not be able to downgrade to the old software because of updates to the security policy

The update = G99*BXXU3AUE1

Download = 1149.41 MB (TBC)

Build date = 01 May 2021

Release date = 06 May 2021

Camera version = 11.0.02.96
