Samsung has begun delivering the stable One UI 8.0 (Android 16) update to its 2023 foldable flagships, the Galaxy Z Fold 5 and Galaxy Z Flip 5. The release, first available in South Korea for beta participants, brings a visual refresh and several new features alongside performance and security improvements.
What this update includes
The One UI 8 package updates the system UI, refines multitasking on foldables, and introduces new customization options and system-level tweaks. The initial build spotted in Korea is firmware version F946NKSU5FYI8 and weighs about 423.12MB. Samsung community reports show the update rolling out to users who previously enrolled in the beta program, confirming the stable release is now live for those devices.
Rollout timing and where it’s headed next
Samsung’s official schedule listed the stable One UI 8 rollout for the Z Fold 5 and Z Flip 5 in October for Korea, with subsequent launches planned for other markets. According to the company, Brazil and India are set to receive the update in October and November respectively. Given Samsung’s tendency to accelerate regional rollouts once the build is stable, expect availability in additional countries sooner than the calendar suggests.

How to check and install the update
To install One UI 8 on your Fold 5 or Flip 5, go to Settings » Software update » Download and install. If the update hasn’t reached your region yet, it may appear first for users who joined the beta. Samsung will also add the official firmware to its database once the international rollout begins, making manual downloads possible for advanced users.
Conclusion
This stable One UI 8 release marks an important milestone for Samsung’s 2023 foldable lineup, delivering Android 16 and a refreshed user experience. If you own a Galaxy Z Fold 5 or Z Flip 5, keep an eye on the Software update menu and community channels for the official regional arrival.
