Samsung is already preparing for its next major software update, One UI 9, even though One UI 8.5 has not been fully rolled out yet. Recently, several Galaxy devices appeared on Samsung’s internal servers running test builds of One UI 9, hinting at the next update’s progress.
Quick Summary
- 🔹 Test builds of One UI 9 have been spotted for Galaxy Z Fold 8 and Z Flip 8
- 🔹 A possible third foldable device named Galaxy Wide Fold may launch
- 🔹 Testing has also started for Galaxy Z Fold 7
- 🔹 Samsung is currently focusing on Galaxy S26 series and One UI 8.5
Which Devices Are Being Tested for One UI 9?
The first foldable devices to appear with One UI 9 test builds were the Galaxy Z Fold 8 and Galaxy Z Flip 8. Both foldables are expected to launch around July 2026 with One UI 9 pre-installed.
Interestingly, a mysterious third device with the model number SM-F971U has appeared, running build F971USQU0AZB1. This may indicate that Samsung plans to introduce a third foldable phone alongside the Fold 8 and Flip 8 in the second half of the year. Rumors suggest it could be called Galaxy Wide Fold, but the official name is not confirmed.
Additionally, test builds for Galaxy Z Fold 7 have also appeared. This is slightly surprising since the Fold 7 has not even received the One UI 8.5 update yet.
List of Devices Under Testing
Currently, Samsung’s internal test list for One UI 9 is small:
| Device | Notes |
|---|---|
| Galaxy Z Fold 8 | First test builds observed |
| Galaxy Z Flip 8 | First test builds observed |
| Galaxy Wide Fold | Possible new device, unconfirmed |
| Galaxy Z Fold 7 | Testing started despite pending 8.5 update |
This list will expand in the coming weeks, especially after One UI 8.5 becomes widely available. Samsung will gradually shift its focus toward One UI 9.
Important Notes About Release and Availability
Testing for One UI 9 is currently internal, meaning you cannot download or install these builds on your Galaxy devices yet. The presence of these builds on Samsung servers indicates the company is preparing the software to ensure a smooth and stable public release in the future.
While Samsung has started developing One UI 9, its current main focus is the Galaxy S26 series, which will launch later this month with One UI 8.5. Additionally, One UI 8.5 is expected to start rolling out for older Galaxy devices around late April 2026.
Conclusion
Samsung is slowly preparing for its next major software update, One UI 9. Early test builds for foldable devices like the Z Fold 8, Z Flip 8, and possibly the Galaxy Wide Fold indicate that the company is working to bring a stable and improved experience to users. If you own a Galaxy foldable device, expect exciting new features in the near future!
