[ironass]

Only 7 days after their second December update, BUL6, Samsung has begun rolling out their 5th Android 12 release for the S21 series of international devices.

Initially, as always, this is a staged rollout to the non-carrier branded, stock Samsung CSC codes first.

The Galaxy S21 international 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*BXXU3BUKG/BUL1/BUL6 builds on the international devices.

Changelog

• Device security improved
• Bugfixes
• After upgrading you will not be able to downgrade to the old software because of updates to the security policy.

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.

Hello. When will it be available for Singapore sIngtel (SIN) ? My device is in BUK8. And has not received an update for a very long time. Now that the New Year is approaching, will there release an update? Because Sam Mobile site has not updated the firmware list for several days.

I see what you mean. All 4 of the Singapore CSC codes are still on the original Android 12 update, BUK8 from almost 6 weeks ago and on the November security patch. Unfortunately, I cannot give you a definitive date for your next update as yours is a carrier branded model and it depends on Singtel certifying the firmware. This late on in the month, I would hope that they hang on for the January 2022 Android Security patch and update.
