Consistent software maintenance is a key component of the flagship experience. In the Android industry, Samsung and Google are the leading players in this area. For some time now, the South Korean giant has been delivering timely monthly patches to its flagship devices. Now, Samsung is releasing the November 2025 security patch to the popular Galaxy S25 series.
This update includes fixes for the Samsung Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and even the Galaxy S25 FE models.
The November 2025 security patch for the Galaxy S25 lineup is here
While often viewed as routine, monthly security updates ensure device integrity and protection. The current update package, which is approximately 550MB and has the S93xNKSS7BYK5 build number, focuses solely on addressing vulnerabilities. According to the details provided in Samsung’s security bulletin, the firmware contains fixes for two critical and several high-risk security issues found in the previous operating system version.
As usual, the rollout began in South Korea. However, the company has already expanded it to countries across Europe, Australia, the Middle East, and India. US users will likely receive an availability notification in the coming days. Given the importance of this market for the Galaxy line, the update should not take long to be available for both carrier models and unlocked devices. Galaxy S25 owners can manually check for the firmware by navigating to Settings > Software update > Download and install.

Attention turns to One UI 8.5
Beyond routine security maintenance, user attention often turns to the company’s next major feature release. For the S25 series, that means the One UI 8.5 beta program.
Unlike the current security patch, One UI 8.5 will be a substantial functional upgrade. Reports suggest the new software will introduce updated Galaxy AI features and significant tweaks to the user interface. Additionally, this release could use the latest Android Quarterly Platform Release as a base.
The initial timeline for the beta program seems to have been tweaked. While originally slated for late November, the public beta is now more likely to begin in December or January. This program will give fans a first look at the next wave of improvements for the current Samsung flagship.
