The next big update to Samsung’s software, One UI 8.5, is inching closer to release—bringing new features to flagship phones early in 2026.
One UI 8.5 Enters Testing Phase for More Galaxy Flagships
Samsung is ramping up development of One UI 8.5, with testing now underway for the Galaxy S23 Ultra, Galaxy Z Flip 6, and Galaxy Z Fold 6. After debuting the beta on the Galaxy S25 series, the company is preparing to bring the update to more recent high-end models.
- Firmware version S918BXXU8FYLB confirms development for the Galaxy S23 Ultra.
- Versions ending in DYLB have also been spotted for the Z Flip 6 and Z Fold 6.
This marks a significant milestone toward a wider rollout, expected in Q1 2026.
Stable Release Expected by Galaxy S26 Launch
Samsung typically releases four to five beta versions before pushing out a stable update. If that schedule holds, One UI 8.5’s stable release could coincide with the Galaxy S26 launch, likely in February or March 2026.
- The second beta for the Galaxy S25 is expected within weeks.
- Broader device support will follow once stability improves.
What’s New in One UI 8.5?
Although still based on Android 16, One UI 8.5 introduces several notable enhancements and design tweaks aimed at refining the user experience:
- Fully customizable Quick Panel for better control over toggles and shortcuts.
- Updated design language across core Samsung apps for improved consistency.
- Auracast improvements, enhancing Bluetooth broadcasting for shared audio.
- Enhanced lock screen clock widget with new fonts and layout options.
- Continuous image generation using Galaxy AI for creative content creation.
- New features like Storage Share and Quick Share suggestions for easier file transfers.
- A time zone converter built into the Clock app for global users.
These features continue Samsung’s strategy of layering smart, AI-powered capabilities on top of Android’s core upgrades.
What Devices Will Get It Next?
The Galaxy S23 Ultra, Z Flip 6, and Z Fold 6 are just the start. Samsung is likely to expand One UI 8.5 to other 2023–2025 flagship and upper mid-range devices soon after the stable release.
Expect devices like:
- Galaxy S24 series
- Galaxy Z Flip 5 and Z Fold 5
- Select Galaxy A-series models (likely upper-tier)
Support will vary by region and carrier, but Samsung’s recent track record with updates suggests a quick rollout for most modern devices.
