Samsung is pushing One UI 9.0 Beta 4 to Galaxy S26 devices, and this update directly addresses interface glitches that disrupt daily phone use. The changes matter because they fix visual bugs that interfere with lock screen interactions and in-game navigation. Users relying on the Privacy Display feature or Quick Panel shortcuts will see more stable behavior in these specific areas.
Beta update rolls out to India and Europe while US waits
The software update targets the Galaxy S26 series and arrives as firmware version ending in ZZG4. This beta release carries a download size of approximately 1.25GB for affected devices. Samsung rolled out the update first in India before expanding the availability to other regions.
- Firmware Version Suffix: ZZG4
- Download Size: 1.25GB
- Security Patch: July 2026
Key technical fixes include improvements to the lock screen clock size when rotating the device horizontally or vertically. The update also resolves issues where the navigation bar disappears during gameplay under certain conditions. Samsung improved the stability of the Quick Panel when opening and closing it frequently.
Additional fixes address timer notification numbers that were previously cut off or caused instability in Live notifications. The update improves Bluetooth audio media volume control when connecting to vehicle Bluetooth via the Routines app. Samsung also fixed an issue where the Privacy Display routine failed to operate normally when toggled via Quick Panel or Settings.
The rollout began in India and has since expanded to the UK, Poland, Germany, and Korea. The United States currently remains pending for this beta update, though the rollout could begin at any moment. We looked at the last Galaxy S26 update earlier while tracking Samsung releases.
