Samsung have begun rolling out the first official stock update of Android 12, One UI 4, for the S21 series of devices...

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*BXXU3ZUK1 / G99*BXXS3AUJ7 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. Alternatively, you can connect to the Samsung PC suite, Smart Switch and check via that.

Is Google pay working for you after wiping the cache partition? Mine is still saying device is not certified.

Definitely wipe cache. Mine was lagging terribly after update but I was super charging and phone was quite warm so it could have been throttling.

I do not use Google Pay but it does not surprise me that it is not working as Samsung do not certify their Beta releases, that this BUK8 is based on, with Google for Pay. Give it a day or two.

You must go to Settings -> Apps -> Google Play Store -> Storage and clear cache and next clear data. In the next step, do the same for Google Pay (Settings -> Apps -> Google Play Store -> Google Pay and clear cache and clear data). 

Next You must reboot phone in recovery mode (how to do it is above) and Wipe the phone's cache partition.

After Reboot run first Google Play Store -> Settings -> About and check Play Protect certification. It should be your device is certified. Next run Google Pay and pay by phone

Just downloaded mine on EE. For my Exynos S21 Ultra. 2.76Gb file size. After updating software updates and clearing the cache my phone normally gets very warm but following this update and clearing the cache (10 minutes ago now) my phone was barely warm at all. 👍 👍
