Samsung has commenced the rollout of its November 2026 security update for the Galaxy Z Fold 7 and Galaxy Z Flip 7 in South Korea, according to Android Headlines.
The firmware version for the Galaxy Z Fold 7 arrives as F966NKSSECZK1 with a file size of 620.33MB. Users in the home market can access the package by going to System Settings, selecting Software update, and hitting Check for updates.
Google supplied 155 of the total 179 patches included in this release. Samsung engineered the remaining 24 fixes to target vulnerabilities in Exynos chipsets, modems, bootloaders, SIM locks, and core system applications.
Samsung Develops One UI 9.5 on Android 17
Parallel to the security deployment, Samsung is advancing work on One UI 9.5. Both foldables will adopt the upcoming interface framework according to the manufacturer’s roadmap, though public beta tests are expected before the stable rollout.
One UI 9.5 will run on Android 17 as an incremental release. Engineers are positioning the software to lay the foundation for a much larger One UI 10 platform update.
