The Galaxy S21 series was the first to receive Android 12 and One UI 4.0 earlier this month. Samsung is now rolling out another update for the Galaxy S21 series, promising more fixes and stability improvements. The latest firmware also prompts Galaxy S21 owners to update a handful of Samsung apps if they want to continue using them.

We’re nearing the end of November, and a few Galaxy phones have already received the December 2021 security patch. However, the latest Galaxy S21 update is accompanied by the November security release, which means that Samsung should soon follow up with another firmware update aimed at improving security. The December 2021 security patch rolled out for the Galaxy Z Fold 3 running Android 12 beta, but it’s only a matter of time before it hits the air on devices running live firmware.

Circling back to the new update, users can identify it by firmware version G99xBXXU3BUKG. The changelog states that once users apply the new firmware, they’ll also have to update several Samsung apps, including SmartThings, Samsung Members, Smart Switch, Samsung Internet, and Calculator.

Samsung is rolling out the new firmware update for the Galaxy S21 series in Germany. It should soon reach additional markets. You can check for the update in your market by launching the Settings app on your phone and navigating to Software update, or you can refer to our firmware database and download the firmware files manually.
