As is typical for flagship phones, the Galaxy S25 series was the first to get One UI 8. The company has also expanded the firmware availability to more Galaxy phones. Now, the Galaxy S25 series is getting its first post-One UI 8.0 update (based on Android 16). First of all, this OTA brings the security patch for the month of October 2025.
Owners of the international variants of the Galaxy S25, Galaxy S25+ and Galaxy S25 Ultra can now get their hands on this release. However, users of the recently announced Galaxy S25 FE will have to wait a little longer.
The Samsung Galaxy S25 series will receive an October security patch
What does this update actually fix? While not a feature release, it is critical for security. The October 2025 patch bundles fixes for about three dozen vulnerabilities. This issue combines patches from Google’s Android operating system and Samsung’s own software, addressing very serious bugs specific to Galaxy devices. The security team focused on patching vulnerabilities related to critical components such as the fingerprint trustlet, Samsung DeX, Knox security features, and even storage issues with the Galaxy Watch. Essentially, this patch closes the security holes that could be exploited by malicious parties.
The rollout has currently started in specific regions in Asia, including Thailand. The update package weighs over 560 MB and contains the firmware version S93xBXXS6BYIF. Users in other global markets can expect the notification to appear on their devices in the coming hours and days.
You can easily check whether your Galaxy S25 has received the patch. Just open the Settings app, scroll to Software Update and select Download and Install.
Now that the October security update is behind us, Samsung’s focus shifts to its next major software initiative: the development of One UI 8.5. Early reports suggest that this version will bring new features and visual tweaks. This firmware will likely debut in early 2026 alongside the Galaxy S26 series. For now, users can rest easy knowing that the biggest security risks have been addressed.
