Samsung releases fourth One UI 9 beta for the Galaxy S26 series | Infinium-tech
Almost a month after releasing the third One UI 9 beta for Galaxy S26 devices, Samsung has started rolling out the fourth beta today. It appears that it will be available in India first, with the firmware version ending in ZZG4.
If you’re enrolled in the One UI 9 beta program, you’ll definitely get it soon as an over-the-air update. It comes in at around 1.25GB, so make sure you download it on a fast enough network. The changelog mentions several bug fixes as you can see in the screenshot below.
Issues with clock size, quick panel, navigation bar, timer notifications, and routines apps have been fixed. The new build also includes the July 5, 2026 security patch level.
One UI 9 will make its official debut on the Galaxy Z Fold8, Fold8 Ultra, and Flip8, which are due to arrive later this month – with the official announcement set to take place on July 22. Samsung will then release it as an update for older devices.
