July 2025 One UI 8 Build Enhances User Experience for Galaxy S25 Ultra
Samsung is actively testing a new July 2025 One UI 8 build for the Galaxy S25 Ultra, focusing on refining the user experience rather than adding flashy features.
- The latest BYG1 version introduces smoother performance and key updates to the home screen, gallery, and camera apps.
- Running on Android 16, One UI 8 has been available in Open Beta since May 2025, and Samsung appears to be preparing for a stable release soon.
Notable System Improvements and Kernel Upgrade
This build brings a significant kernel update—from version 6.6.57 to 6.6.77—the first major jump since One UI 8 testing began.
- Discovered by tipster UniverseIce, this change delivers a more fluid and responsive experience across apps and menus.
- Instead of introducing new features, the update prioritizes a polished, lag-free interface.

Enhanced System Apps and User Interface
The July build rolls out updated versions of key system apps:
- One UI Home sees improvements to gesture animations and transition effects.
- Samsung Gallery and Camera receive version bumps, hinting at further upgrades for photo management and photography capabilities.
- These changes collectively contribute to a seamless and more enjoyable daily use for Galaxy S25 Ultra users.
Rollout Plans and Device Eligibility
One UI 8 is expected to debut on Samsung’s new foldables launching this summer, with the fresh OS pre-installed.
- The Open Beta remains exclusive to Galaxy S25 owners in six countries; there is no confirmation yet on Beta expansion to older models such as the Galaxy S24 and S23 series.
- Most Galaxy devices are likely to receive the official update directly, bypassing the public Beta Program.
Looking Ahead
While details about further features remain limited, Samsung’s focus with this update is clear: improving stability, speed, and overall user satisfaction.
- Galaxy users can anticipate a more refined experience as One UI 8 approaches its stable rollout, bringing meaningful enhancements to the Galaxy ecosystem.
