Samsung continues to release a new update to its eligible phones as the company prepares for the stable One UI 7 release. The latest build that brings the February 2025 security patch fortifies the device for the upgrade and resolves some issues.

While the Galaxy S21 series might wait until June before receiving the One UI 7 update, every new update means a seamless transition to Android 15. Hence, we recommend installing all the updates released for the device while waiting for the major ones.
Aside from resolving over 40 security flaws, the Galaxy S21 February 2025 security patch update fixed the audio output issues in Android Auto. A new update was released for the navigation app a few days ago, you should also install that.
Meanwhile, the update has version number G99xBXXSEGYA2, exclusive to European users. We understand it’s a staged rollout and will take some days before arriving for all eligible phones, but you can check for it manually.
