While the One UI 8.5 release is yet to happen, Samsung is already laying the groundwork for its next major release, One UI 9. A few Galaxy devices have been spotted on Samsung’s test servers with new build versions pointing to One UI 9.
The Galaxy Z Fold 8 and Galaxy Z Flip 8 were the first phones to show up on the server with One UI 9 test builds (1, 2). Both foldables will launch around July 2026 with One UI 9 right from the box.
Perhaps the most intriguing is the appearance of a mysterious third device with the modem number SM-F971U running the build version F971USQU0AZB1. This could mean Samsung might also launch a third foldable phone alongside the Fold 8 and Flip 8 in the second half. We don’t know what it would be called, but rumors say this could be the Galaxy Wide Fold.
Alongside these three upcoming foldable phones, the One UI 9 test build has also been spotted for the Galaxy Z Fold 7. This is kind of surprising, as the Galaxy Z Fold 7 hasn’t even received the One UI 8.5 update.
So, here’s a list of Samsung devices that are currently under One UI 9 testing:
- Galaxy Z Fold 8
- Galaxy Z Flip 8
- Galaxy Wide Fold (name unconfirmed)
- Galaxy Z Fold 7
The list is currently small, as Samsung began testing One UI 9 just recently. It will grow in the coming days, especially after the One UI 8.5 release, when more of the company’s focus will shift towards One UI 9.
It’s important to highlight that One UI 9 testing is happening internally, so you can’t download and test the firmware on your Galaxy device. The presence of such test builds on the server indicates that the company is testing the firmware behind closed doors to ensure a stable, smooth rollout in the future.
While Samsung has begun development of One UI 9 for its Galaxy devices, its primary focus will be the Galaxy S26 series, which is launching later this month with One UI 8.5. In late April, we might see One UI 8.5 rolling out to older Galaxy devices. You can check the list of eligible devices here.
