Samsung has begun the December 2025 update rollout for more Galaxy devices in their home country. Following a couple of new flagships smartphones and foldables, the brand has now rolled out December security patches for the Galaxy S24 FE, Z Fold6, Z Flip6, and Tab S10 in Korea.
The fresh update for these Galaxy devices comes with the same changelog, which addresses that the update is mainly focused on the security improvements. It brings more than 60 Android security patches to address various moderate to critical vulnerabilities.
Along with the improved security, the devices are also getting system stability improvements in certain scenarios. This maintenance update should not be ignored if it is your primary device and has important private data.
December 2025 update builds
Galaxy S24 FE users can verify the update with build version S721NKSS8CYL1. Meanwhile, the Galaxy Tab S10 (Wi-Fi) is getting it with version X820XXS5CYK1, and the software size for the tab is 400 MB.
On the other hand, the Galaxy Z Fold6 and Flip6 users are receiving the latest security patches with software versions F956NKSS2CYKE and F741NKSS2CYKE, respectively. Both foldables are getting an OTA update in a package size of 450 MB.
In addition, all of these Galaxy devices are also eligible for the upcoming One UI 8.5. However, the One UI 8.5 beta program is already live for the Galaxy S25 series, but these older devices will probably get the direct stable version.
