Samsung has done it again! It has released a new security update to its smartphones even before the start of the month. The Galaxy S21, Galaxy S21+, and the Galaxy S21 Ultra have become the first smartphones to get the October 2021 security update.

The new update is currently rolling out in Germany and the Philippines, but more markets could soon get access to this new software. The latest software update for the Galaxy S21 series comes with firmware version G991BXXU3AUIE, and it includes the October 2021 security patch. However, Samsung hasn’t detailed which vulnerabilities it has fixed with the new update.

If you are a Galaxy S21 series smartphone user in Germany or the Philippines, you might have already received a notification of the new update. If you haven’t received it yet, you can check for it manually by navigating to Settings » Software update and tapping on Download and install. You can also download the new firmware file from our firmware database and flash it manually.

The Galaxy S21 series was launched earlier this year with Android 11-based One UI 3.1 on board. A few weeks ago, the smartphones received the One UI 3.1.1 update with slight UI changes and performance improvements. These smartphones could soon get the Android 12-based One UI 4.0 update which is currently being tested.
