Samsung has reportedly started internal testing of One UI 9 for the Galaxy S25 series, marking another step toward the release of its next major software update. The Android 17-based interface is already being tested on several Galaxy devices, and the company now appears to be expanding development to its current flagship lineup.
One UI 9 Development Gains Momentum
The latest report comes shortly after Samsung released two One UI 9 beta updates for the Galaxy S26 series. In addition, testing has reportedly begun for the upcoming Galaxy S26 FE, even though the smartphone has not yet been officially announced.
With the Galaxy S25 series now joining the testing phase, Samsung is accelerating preparations for a wider rollout of the new software experience.
Public Beta Could Arrive Soon
At this stage, the exact build version being tested for the Galaxy S25 family remains unknown. However, industry sources suggest that Samsung may launch the first public One UI 9 beta program for Galaxy S25 users in the coming weeks.
A beta release would give users early access to new features, performance improvements, and design refinements before the stable version becomes available.
Upcoming Foldables to Debut One UI 9
Samsung has already confirmed that its next-generation foldable smartphones will be the first devices to ship with One UI 9 out of the box. This makes the upcoming foldable lineup an important part of the software’s official debut.
The company is expected to showcase the latest software alongside its new premium foldable devices later this year.
Galaxy Z Flip8, Fold8, and Fold8 Ultra Expected
According to recent rumors, Samsung is preparing to launch three foldable smartphones in 2026. These include the Galaxy Z Flip8, Galaxy Z Fold8, and the Galaxy Z Fold8 Ultra.
All three devices are expected to feature the newest version of Samsung’s Android interface from day one.
Possible Launch Event in July
Reports suggest that Samsung could unveil its next foldable lineup during a Galaxy Unpacked event scheduled for July 22 in London. While Samsung has not officially confirmed the date, multiple leaks point to a late-July announcement.
If the rumors are accurate, the event will introduce both the new foldable devices and the first commercial release of One UI 9.
What to Expect Next
With internal testing now underway for the Galaxy S25 series, Samsung appears to be moving steadily toward a broader One UI 9 rollout. More information regarding new features, supported devices, and beta availability is expected to surface in the coming weeks as the launch draws closer.
