Finally, Samsung’s high-end S series joins the November 2025 security update rollout, as the company has started delivering the update for the Galaxy S24 series.
Well, until now, Samsung was delivering the update for its budget models, but after the Galaxy Tab S11 series, the company is providing the November 2025 security update for the previous generation flagships, the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra, where the update is initiated from South Korea, and more countries will follow the update soon.
Essentially, the latest firmware for the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra has been identified with the S921NKSS4CYK2, S926NKSS4CYK2, and S928NKSS4CYK2, respectively.
According to the details posted, the latest November 2025 security update, however, doesn’t bring any major features or changes, but it significantly focuses on improving the device’s overall security and core functionality.
The update packs a handful of fixes for all the security vulnerabilities that have been brought up by both Samsung and Google collectively to provide a secure user experience, while also protecting the device against external threats or attacks.
Other than that, the latest update apparently adds stability and reliability to the entire system behavior for a more efficient functionality, and brings certain performance optimizations that eventually leads to a smoother, stable, and optimized experience for the users.
Nevertheless, Samsung has already started adding its premium Galaxy devices to the November 2025 security update list, such as its S series. More models will join the release over the coming weeks.
