Samsung Galaxy Z Flip 8: First One UI 9 Test Build Spotted Ahead of 2026 Launch

While the tech world is currently fixated on the imminent arrival of the Samsung Galaxy S26 series later this month, enthusiasts of the foldable form factor are already looking further ahead. The second half of 2026 is set to be a transformative period for Samsung's clamshell lineup, and recent evidence suggests that the groundwork for the next generation is already being laid behind the scenes.

The Galaxy Z Flip 8 is poised to be a headline act during the company's summer Unpacked event later this year. In a surprising turn of events, it appears that Samsung has already triggered the development phase for the One UI 9 firmware specifically tailored for this upcoming foldable powerhouse.

Galaxy Z Flip 8: Preparing for One UI 9 and Android 17

As highlighted by the well-known leaker  on social media, a specific firmware version identified as F776USQU0AZB1 has been detected. This version is widely believed to be an early One UI 9 test build intended for the next-generation clamshell. For context regarding the internal naming conventions, the model number SM-F776 is reportedly assigned to the Galaxy Z Flip 8.

While hardware details remain scarce, early industry whispers suggest that the device will be equipped with the Exynos 2600 chipset. This follows the established pattern, as the current Galaxy Z Flip 7 launched with the Exynos 2500. Given that Samsung traditionally pairs its latest hardware with the newest software iterations, the transition to Android 17 is almost a certainty.

Last year, the Galaxy Z Flip 7 hit the shelves running One UI 8 based on Android 16. If Samsung maintains its current release cycle, the Galaxy Z Flip 8—and its larger sibling, the Galaxy Z Fold 8—will serve as the launch platform for One UI 9. We can expect a steady stream of leaks and further firmware sightings as we move closer to the official unveiling in the coming months.
