Galaxy S23 gets the November 2025 security update

Samsung has started rolling out the November 2025 security patch to the Galaxy S23 series. It fixes 25 security issues.

After the Galaxy S25 and the Galaxy S24 series, Samsung is now rolling out the November 2025 security patch to its non-foldable flagship smartphone lineup from 2023, the Galaxy S23 series.

Currently, the brand is offering the update in Europe and India (via Tarun Vats). It is 405.75MB in size and carries firmware version S91xB0XM8EYK2.

The November 2025 security patch fixes 25 security vulnerabilities present in the previous versions of the OS. To get it, go to Settings > Software update > Download and uninstall. We expect Samsung to release it to other variants of the Galaxy S23 series phones and in other regions in the next few days. We will soon make the firmware available in our database for you to download and install manually.

If you have been following Samsung news, you might know that the company is developing One UI 8.5 for Galaxy smartphones and tablets. Every new test build of the software packs more visual changes and new features than the one before it. Samsung is expected to debut it with the Galaxy S26 series in February, and the Galaxy S23 is eligible to get it.
