This latest update is the 6th for the Global, Exynos, S21 & S21+ and is currently being rolled out by Samsung.
It would appear that this is a bugfix for the previous release, AUB6, as well as a camera update.
The Galaxy S21 Global, Exynos, devices that will receive this update are...
- S21 5G model SM-G991B
- S21+ 5G model SM-G996B
This latest release replaces the G99*BXXU1AUB6 February build. No news on whether this will also apply to the Ultra model at the moment.
Initially, as always, this is rolling out to the non-carrier branded, stock Samsung CSC codes first. (U.K. = BTU)
It is a FOTA, (Firmware Over The Air), update and you can check... Settings > Software update... to see if it is available for you
