One UI 9.5 development moves forward for Samsung’s latest flagship phones

Samsung’s One UI 9.5 development is moving forward. New internal test builds have been spotted for the Galaxy S26 series and the latest foldable phones. These new builds show that Samsung is actively working on its next One UI version.

A new One UI 9.5 test build has been spotted for the Galaxy S26 series. The build has moved from U4CZJ1 to U5CZJ5. The full software version is S94xBXXU5CZJ5. The new build is currently an internal test version. Samsung is likely using it to test the software, fix bugs, and improve the overall performance before the update reaches users.

Samsung is also testing One UI 9.5 on its latest foldable phones. New One UI 9.5 internal builds have been spotted for the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and Galaxy Z Flip 8. For these foldable devices, the build has reportedly moved from U2BZJ1 to U3BZJ5. This shows that Samsung is also working on One UI 9.5 for its foldable lineup.

These new test builds are a sign that One UI 9.5 development is active. Samsung is testing the software on different flagship devices and making changes before the final version is ready. However, these are internal builds, so the features and changes can still be modified before the public release.

Samsung has not yet officially announced the public release date for One UI 9.5. More test builds may appear in the coming months, giving us more information about the update. For now, the latest builds confirm that Samsung is continuing its work on One UI 9.5.
