Samsung released the November 2024 software update to the Galaxy S21 series last week, and following a few days of limited availability, that update is getting a wider rollout. Some Asian countries have started receiving the update this week, and more countries—in Asia and other regions—should join the party over the coming days.
The November update for the Galaxy S21, S21+, and S21 Ultra was first released in the USA and brought only security fixes. But that's not the case for the update that's rolling out in other countries.
The newer version of the update—sporting the build number G99xBXXUEGXJE—also packs stability improvements, similar to the November update for newer flagships like the Galaxy S24 and Galaxy Z Flip 6, though Samsung hasn't detailed those improvements in the changelog.
As always, you can try downloading the latest update directly on your phone using a Wi-Fi or mobile data connection from its Settings » Software update menu. Alternatively, you can download the full firmware from our archive and install it on the phone using a Windows PC and a USB cable.
While you're downloading the update, or after installation is over, check out the video below to learn about what the next major OS upgrade (Android 15 with One UI 7.0) will bring to your Galaxy S21-series smartphone. But don't expect to get the chance to use Android 15 and One UI 7.0 anytime soon, as the official release is set for 2025 and there may not be a One UI 7.0 beta program for the Galaxy S21 lineup.
