Samsung released the seventh beta release of One UI 9 for the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra on August 28, 2026, targeting registered users in South Korea, India, Germany, Poland, and the United Kingdom. This rollout carries the firmware build ending with the ZZHK identifier.
The package exceeds 1.2 GB. Users must allocate adequate storage space on the handset before downloading the large system installer. This download size applies to all three compatible flagship phones.
Interface tools ported from the Galaxy Z Fold8
Samsung omitted specific feature mentions from the official changelog but incorporated several interface capabilities previously exclusive to the foldable Galaxy Z Fold8 so owners can customize visual layouts on flat displays. The test package delivers everyday interface modifications directly to the conventional smartphone line:
- Customized cards integrated into Now Brief
- My FanCam image capturing tool
- Combined widgets pairing Finder and Google Search on the home screen
Enrolled testers located in the five eligible territories without an automatic notification can pull the update manually. Owners must open the device settings menu. Selecting the software update option initiates the file download.
