Summary
- Samsung seems to be testing One UI 9.5 shortly after the official One UI 9 launch.
- The new build reportedly pertains to the Galaxy S27 Ultra.
- Currently, no additional details about the upcoming interface are available.
Samsung recently introduced its latest firmware, One UI 9, only a few weeks ago. This version is currently limited to the Galaxy Z Fold 8 series, including the Fold 8 Ultra and Flip 8. Despite a beta version for the Galaxy S26 series being accessible for some time, Samsung has not disclosed timelines for the broader rollout of One UI 9 to other devices. Nevertheless, development appears to be under way for the next version, One UI 9.5.
Initial reports suggest that the first build of One UI 9.5 has appeared on Samsung’s testing servers, indicating that its development is actively underway. According to insider information shared by Fahad Ali Javed, this build is linked to the US version of the forthcoming Galaxy S27 Ultra. This inference comes from the build number starting with “S958U,” which indicates a new model number distinct from the Galaxy S26 Ultra’s SM-S948U designation.
The build’s designation aligns with Samsung’s recent trends regarding versioning for minor updates. The mention of One UI 9.5 alongside the Galaxy S27 Ultra is not surprising, as it mirrors the timeline of previous updates like One UI 8.5, which was initially referenced in July 2025.
Given that One UI 9 has just been launched, it is unlikely that a successor will debut anytime soon. Additionally, predicting the launch window for the Galaxy S27 series remains uncertain, although it could occur in early 2027. Furthermore, we are still awaiting information about the potential new features that may be introduced in One UI 9.5, and we hope for early leaks to surface before an official beta release is announced.
