Samsung rolls out the latest security patch to its foldable flagships while preparing for the next major update: One UI 8.5.
December Security Patch Hits Galaxy Z Fold 7 and Flip 7
Samsung has begun rolling out the December 2025 security update for its latest foldables, the Galaxy Z Fold 7 and Galaxy Z Flip 7, starting in South Korea. The update brings critical security improvements as the company prepares to launch One UI 8.5 for these devices in the near future.
The firmware versions are:
- F966NKSS6AYKE for the Galaxy Z Fold 7
- F766NKSS6AYKE for the Galaxy Z Flip 7
What Does the Update Include?
The December 2025 security patch addresses 57 known security vulnerabilities found in the previous version of the OS. These fixes cover potential risks in both Android OS and Samsung’s One UI software layer, enhancing the overall safety of your foldable device.
Users in Korea can check for the update by navigating to:
Settings > Software update > Download and install
The update is expected to roll out to other regions globally in the coming days.
One UI 8.5 Is Coming Next
While the December patch is purely a security-focused update, a bigger software upgrade is on the horizon. One UI 8.5, based on Android 16, has already entered beta testing for the Galaxy S25 series. The Galaxy Z Fold 7 and Flip 7 are next in line to receive it.
A recent leaked firmware for the Galaxy Z Fold 7 hinted at new features and optimizations tailored for foldable devices in One UI 8.5. Beta testing for these foldables could begin within weeks.
What to Expect from One UI 8.5 on Foldables
Although official One UI 8.5 details for foldables haven’t been confirmed, expected improvements may include:
- Enhanced multitasking for the large inner display
- New cover screen functionality (especially for Flip 7)
- AI-driven optimizations and battery management
- Improved stylus support and Flex Mode features (Fold 7)
Samsung continues to refine the foldable experience with each update, and One UI 8.5 is likely to bring meaningful quality-of-life enhancements.
