N.B. Not to be confused with the second August update and Security patch... AUHB

 

This latest release is the 17th for the Global, Exynos, S21 series and is currently being rolled out by Samsung only 11 days after the second August update, AUHB which is still, currently, being rolled out.

 
This update is for device security.
 
Initially, as always, this is a staged roll 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 previous G99*BXXU3AUHB build.
     
    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 suiteSmart Switch and check via that.

As far as I can tell and from the, "S", in the Build number, this is just for the September Android Security patch on the previous, AUHB, update. Both CSC and Baseband are unchanged from AUHB.

I think this is the final update before One UI 4.0 beta 😁 can't wait to see what's new.

Samsung update AUHD

As suspected by @GoanGeek, this update is merely the September Android Security patch.

I also tend to agree with @adamlee, that this quick release, so soon after the previous AUHB, indicates a readiness for the Android 12 Beta One UI 4.0 test firmware to be rolled out imminently.

The AUHB seems to be a good update.
