A tweet from Tarun Vats on X indicates a new firmware drop for Samsung’s current foldables. The One UI 8.5 beta program is advancing steadily.
South Korean users participating in the testing phase are now receiving the third beta build for the Galaxy Z Flip 6 and Z Fold 6. The update arrives with the firmware version F741NKSU3ZZDD for the Flip 6.
The update size is 899.09MB. The package also brings the April 5, 2026, security patch alongside the underlying Android 16 operating system.
Based on the localized update screen, this release focuses heavily on system stability and visual polish. Beta testing often introduces frustrating UI glitches. Samsung is addressing several of these directly in this third iteration.
Squashing Android 16 bugs
The official changelog highlights a much-needed fix for screen flickering. Users previously reported this occurring at the bottom of the display when triggering the back gesture. The update also resolves a persistent alignment error with the lock screen clock positioning.
A specific fix impacts the foldable workflow. A bug preventing the taskbar from disappearing has been patched. This should immediately improve the multitasking experience and reclaim active screen real estate on the internal displays.
Audio quality receives attention as well. Samsung’s release notes indicate improvements to random static or noise generation that occurred during video and music playback.
Beyond bug squashing, the changelog explicitly mentions the addition of new AI features. The exact nature of these tools remains unspecified in the brief release notes. They will likely integrate into Samsung’s broader Galaxy AI suite introduced earlier in the development cycle.
The third beta usually represents a turning point in Samsung’s software schedule. The heavy lifting for core Android 16 integration typically happens in the first two releases. The transition toward fine-tuning, audio fixes, and AI feature drops suggests the foundational architecture is stabilizing.
This rollout remains restricted to South Korea for now. Samsung generally expands beta access to markets like the US, Germany, and India in subsequent waves.
With Google moving rapidly through its own Android 16 timeline, the pressure is on hardware partners. How quickly Samsung can push this maturing One UI 8.5 build from beta channels to a global stable release will dictate the update pace for the broader Galaxy S26 lineup later this summer.
