    The updates just keep on coming.

    Only 11 days after their bugfix update, BUKG, Samsung have begun rolling out their 3rd Android 12 release... the December Android Security patch 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 build on the international devices.

    Changelog

    • Device security improved

    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.

    System information



    The update = G99*BXXS3BUL1

    Download = 213.20MB

    Build date = 30 November 2021

    Release date = 07 December 2021

    Camera version = 12.0.00.83 (no change)

    One UI version = 4.0

    Android Security patch = 01 December 2021

    This is the 22nd stable update for the Exynos model in 316 days. Average = 1 update every 14 days.

    TOP TIP: Wipe the phone's cache partition and use the Galaxy App Booster after updating.


    (N.B. This post will be updated as more information becomes available)

    Cool, at 330MB I'm guessing there's more than just a security patch...

    I'm now racing my pixel 6 and S21 Ultra. Although I'm fairly sure Google have managed to tie their own shoelaces together and super glue mittens to their hands...

    I am guessing that it will be in the next 2-4 days as it is only a simple Android Security patch.

    My S21 Ultra via AT&T says it's up to date at the Nov 22 BUKF. So, I guess something is coming since AT&T checks it out.

    Getting closer to coming to the U.S. models. ������������
    I blew my earlier guess... so I am not predicting anything @pags11

    Besides, the G99*0 Snapdragon devices for Chine/Taiwan may be a priority to Samsung as they are still on Android 11.

    As most of us have already seen, there is currently a hiatus in updates for the Galaxy S21 series with many having not received the December 2021 Android Security patch, to-date.


    "Samsung is temporarily pulling the plug on the Android 12 One UI 4.0 update for the Galaxy S21 series in South Korea, as per a recent announcement issued by a Samsung Community Moderator (via TizenHelp). According to it, a few devices are experiencing an error due to compatibility issues with Google Play.The One UI 4.0 rollout won’t resume until Google and Samsung solve the issue. It sounds like the problem may not lie entirely with Samsung, or at all, but whatever the case may be, they are working hard to resume the One UI 4.0 firmware rollout as soon as possible."


    Also applies to the Galaxy Z Flip 3 and Fold 3
