Galaxy S26 Gets One UI 9 Beta 3 with Nine Bug Fixes and a June Security Patch
Samsung is maintaining a tight two-week beta cadence for One UI 9. Just weeks after kicking off the One UI 9 Beta cycle, Beta 3 is now live for the Galaxy S26 series, and it is the most substantive build yet.
Firmware ZZF7 landed today in Germany, India, Poland, South Korea, and the UK at 1,786MB, bundled with the June 5, 2026, security patch. A US rollout is expected to follow within days.
Nine Fixes in One Build
According to Android Authority, which received the update on a Galaxy S26 Ultra in the UK, the full Beta 3 changelog addresses nine specific issues across display, camera, and system stability.
Here is everything that got fixed:
- Privacy display errors: Incorrect behavior when setting routines or toggling Quick Panel ON/OFF while Privacy Display was active
- Camera preview cropping: Part of the camera preview screen was being clipped under certain usage conditions
- Lock screen widget data not refreshing: Weather and battery widgets were failing to update their information correctly
- 30x zoom focus accuracy: Focus precision at 30x optical magnification has been improved
- Home screen swipe failure with S Pen: The home screen was not responding to left/right swipe gestures when the pen was in use
- My Files scroll-to-end bug: The file list in My Files could not be scrolled fully to the bottom
- White background during incoming calls: The background was intermittently flashing white when a call arrived
- Spontaneous reboot during video streaming: The device was rebooting once during active video playback sessions
- Black status bar background: Pulling down the status bar was displaying a black background behind it, rather than the correct blurred or themed surface
Camera Upgrades and Hidden Features
The camera fixes deserve particular attention. Two separate camera issues, preview cropping and 30x zoom focus accuracy, are being patched in the same build, suggesting the Beta 2 camera pipeline touched something that introduced both regressions simultaneously.
Focus accuracy at 30x is critical for the Galaxy S26 Ultra‘s telephoto workflow, so this is a meaningful repair before stable ships.
The status bar’s black background is the kind of visual bug Samsung beta users spot quickly, similar to the rendering issues seen in One UI 8.5, including the dark mode color palette conflict that required a user workaround before a patch arrived.
Beta 3 catching this class of issue early is the beta program working exactly as intended.
Rollout Status and How to Get It
Android Authority confirms the update is live across all beta regions except the US, where Samsung says it will arrive soon.
If you are enrolled in the beta program for the One UI 9 on a Galaxy S26, S26+, or S26 Ultra in one of the five live regions, go to Settings > Software update > Download and install to pull it manually rather than waiting for the automatic prompt.Â
US beta testers who have been enrolled since the program launched in mid-May should expect the OTA within the next 48 to 72 hours based on Samsung’s typical region-staggering pattern.
The stable One UI 9 release remains on track for Samsung Unpacked in London on July 22 alongside the Galaxy Z Fold 8, Z Flip 8, and Galaxy Watch 9 series.
