Samsung updates Galaxy S25 with November 2025 security patch

Samsung is updating the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and Galaxy S25 FE with the November 2025 security patch in Korea.

Samsung, almost two weeks after detailing the November 2025 security patch for Galaxy smartphones and tablets, is finally rolling it out to the Galaxy S25 series.

The update is live for four devices in the lineup, the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and the Galaxy S25 FE, but only in Korea (via Tarun Vats).

The update for the base, Plus, and Ultra models is 531.39MB in size and carries firmware version S93xNKSS7BYK5. It addresses 25 security issues discovered in the previous version of the OS.

We expect Samsung to release the update in other regions in the next few days. To check if Samsung has released it in your region or for your device, go to Settings > Software update > Download and install.
