Samsung kicks off One UI 9 testing early, giving fans an exciting peek at what’s coming for Samsung’s next foldable phones. Leaks show internal firmware builds already appearing for the unreleased Galaxy Z Fold 8 and Galaxy Z Flip 8. This early start means Samsung pushes hard to polish its software based on Android 17 before the foldables launch later in 2026. The news highlights how Samsung prepares updates for both new and current devices at the same time, so owners of older foldables like the Galaxy Z Fold 7 also benefit sooner.
One UI 9 Testing Spotted On Upcoming Foldables
Reliable leakers spot test firmware like F976USQU0AZB1 for the Samsung Galaxy Z Fold 8 and F776USQU0AZB1 for the Samsung Galaxy Z Flip 8 on Samsung’s servers. A mysterious new model, SM-F971U, also shows up with similar One UI 9 builds, hinting at an extra foldable, possibly a wider or more affordable version, in the works.

Testing even reaches current models like the Galaxy Z Fold 7. One UI 9 builds on Android 17 and could launch first on these new foldables. Samsung’s quick move ensures smoother, more feature-packed software by summer.
Galaxy Z Fold 8 And Z Flip 8: Early Expectations
Hardware details stay under wraps, but rumors build excitement around the lineup:
- Galaxy Z Fold 8: Expect a thinner design with less visible screen crease, a possible 200-megapixel main camera in a triple setup, bigger battery (up to around 5,000mAh), and lighter weight compared to the Z Fold 7.
- Galaxy Z Flip 8: Likely features a next-gen chipset on a super-efficient 2nm process, significantly lighter build (rumors say around 150 grams), and bigger battery for longer use.
- Extra foldable (possible Wide Fold): A new form factor with a squarer aspect ratio for better video and multitasking, competing with upcoming rivals like Apple’s foldable.
Samsung plans to ship these devices with One UI 9 and Android 17 ready out of the box. Meanwhile, the Galaxy S26 series might launch with One UI 8.5 first. This early One UI 9 testing shows Samsung’s focus on fast, reliable updates and innovative foldables. Foldable fans should watch for more leaks as summer launch nears, big improvements in performance, battery life, and AI features could make these the best yet.
