Samsung Confirms 4th One UI 9 Beta for Galaxy S26 Next Week

Q: Why will new Foldables get the final One UI 9 before the Galaxy S26 it's being tested on?

The new Foldables will get the final One UI 9 first because Samsung is using them as the launch devices for the stable release, while the Galaxy S26 is serving as the main public test platform. Samsung has confirmed that the S26 series is still on beta builds, with a fourth beta due next week. That means the software on the S26 is still being refined through bug fixes, performance tuning and interface polish before a wider stable rollout. By contrast, the Galaxy Z Fold 8 and Z Flip 8 are expected to debut at Samsung’s July 22 Unpacked event with stable One UI 9 preinstalled. This is a common Samsung release pattern. The Galaxy S series often enters beta testing for the next major One UI version months before Samsung’s mid-year foldables arrive. The beta helps Samsung identify issues on widely used flagship hardware, then the company packages the finished software on newly launched devices. In practical terms, the S26 helps validate One UI 9, but the Foldables become the commercial showcase for it. The timing also fits Samsung’s product strategy. One UI 9’s headline additions, especially Gemini Intelligence and other AI features, are expected to be highlighted on the new Foldables, whose larger screens and multitasking design make them ideal for demonstrating those capabilities. So the S26 is getting One UI 9 earlier in testing, but the Foldables are likely to receive it earlier in final, stable form because they are the planned launch hardware for Samsung’s public rollout.
