Samsung has today started rolling out the fourth One UI 9 beta for the Galaxy S26 devices, almost exactly a month after it released the third beta. This appears to be available in India first, with the firmware version ending in ZZG4. If you are enrolled in the One UI 9 beta program, you will of course receive this as an over-the-air update soon. It comes in at around 1.25GB, so make sure you download it over a fast enough network. The changelog mentions a lot of bug fixes as you can see in the screenshots below. Problems with the clock size, Quick Panel, navigation bar, timer notifications, and the Routines app have been resolved. The new build also contains 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 all coming later this month - the official announcement is scheduled for July 22. Then Samsung will release it as an update to older devices.
