Samsung has reportedly expanded internal testing of One UI 9.5 to additional Galaxy devices, following initial sightings on the unreleased Galaxy S27 series.
Tipster Tarun Vats claims that development for the Galaxy S26 series has begun, with a build version ending in CZH1.
No release timeframe has been provided.
This development comes as users still await the stable rollout of One UI 9.0, which has been in beta for the Galaxy S26 series since May.
One UI 9.0 Beta Progress and Stable Rollout Expectations
Samsung has confirmed that the fifth One UI 9.0 beta for the S26 models will be released this week, but there is no official word on when the stable version will arrive.
The stable build has already debuted on the latest foldable phones launched in July, including the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and Galaxy Z Flip 8.
The beta progress closely mimics that of One UI 8.5, which saw its stable release in the same month last year.
This suggests One UI 9.0 stable could begin rolling out in September.
Samsung is expected to expand the One UI 9.0 beta to the Galaxy S25 series and other devices in the coming weeks.
