Samsung has released a new software update to improve security for the Galaxy S24, S24 Plus, and S24 Ultra. This update carries the latest November 2025 Android security patch to address more than 45 issues.
As the update is currently spotted in Korea, Korean users can identify the new firmware with build versions S921NKSS4CYK2, S926NKSS4CYK2, and S928NKSS4CYK2 for Galaxy S24, S24 Plus, and S24 Ultra, respectively. Additionally, you need to download around 405 MB of update package to install it.
The changelog suggests no new features coming with the latest update but brings system stability and improvements to offer smooth device performance.
This is the third maintenance update following the major One UI 8 for the Galaxy S24 series. After the One UI 8, these flagships are now just a few months away from getting One UI 8.5.
Notably, half of November has passed, and Samsung’s flagship smartphones like the Galaxy S25 series are still waiting for the November 2025 update, while many budget– to midrange-level devices have already received it.
Any Samsung Galaxy device owner can check the software update by navigating to Settings » Software update. » Download and install.
