Galaxy S26 One UI 9 Beta 4 Schedule
Samsung has maintained a steady beta release schedule. The company released Beta 1 on May 13.
Beta 2 followed shortly on May 26. Beta 3 arrived later on June 16. Following this pattern, Beta 4 should arrive soon.
Samsung’s beta program is currently available widely. It supports Galaxy S26, S26+, and S26 Ultra. Users can register through Samsung Members application.
The beta program currently operates across six countries.
- United States
- United Kingdom
- Germany
- India
- South Korea
- Poland
Samsung has improved communication during this cycle. Upcoming beta releases receive advance notices regularly. Users can watch Samsung Members banners carefully.
This approach differs from many previous programs. Earlier beta releases often appeared without warnings. The company now provides better transparency throughout.
Beta 3 officially carried the firmware version ZZF7. The update size reached nearly 1,786 megabytes. It also included June 2026 security updates.
Arriving After Important Improvements
Beta 3 delivered many useful fixes and refinements. Samsung corrected several issues affecting daily usage.
Major fixes included:
- Improved 30x camera zoom accuracy
- Fixed lock-screen widget refresh failures
- Corrected cropped camera preview problems
- Fixed Privacy Display behavior issues
- Added additional stability improvements
The update resolved seven bugs successfully. Samsung also delivered two additional improvements.
One issue still requires further attention. The Finder icon unexpectedly changed appearance again.
Earlier One UI 9 builds showed redesign changes. Beta 3 returned the older One UI 8.5 look. Many users consider this an unintended regression.
Beta 4 may finally correct this issue. Additional system refinements are also expected. Samsung continues collecting feedback from participants.
Arriving Before Stable July Release
Android 17 reached stable status on June 16. This development greatly benefits Samsung’s software efforts.
Engineers now work with finalized Android software. No major platform changes remain ahead. This reduces risks during final testing stages.
Android 17 introduces several performance-focused enhancements.
- Lower power consumption
- Better overall performance
- Reduced interface stutters
- Improved memory management
- Enhanced large-screen support
The Android Runtime received major improvements internally. A redesigned garbage collection system now operates.
It handles memory more efficiently than before. This reduces processor usage during daily tasks.
Android 17 also improves foldable device experiences. Apps targeting API level 37 must adapt. Large screens receive better application support now.
One UI 9 focuses mainly on refinements. It is not a major redesign update.
New features include:
- Combined TalkBack accessibility package
- Text Spotlight reading accessibility tool
- High-risk app detection protection
- Better security enhancements
- Continued Galaxy AI optimizations
Samsung has already tested many devices internally. These include Galaxy S25 series models. Galaxy S24 FE testing is also underway.
Galaxy Tab S10+ and Tab S10 Ultra participate. Internal testing reportedly includes upcoming foldables too. Reports suggest Galaxy Unpacked may happen July 22.
The event could take place in London. Both devices should ship with One UI 9. A rumored Galaxy Z Wide Fold may appear.
The End Note
Beta 4 should arrive near June 30. Stable One UI 9 may launch during July, bringing better performance, security, accessibility, and foldable support.
