For those enrolled in the One UI 9 beta program, this update will be delivered as an over-the-air installation soon. The file size is about 1.25GB, so it's advisable to download it using a stable and fast network. The changelog highlights numerous bug fixes, as illustrated in the screenshots below.
The update addresses issues related to clock size, the Quick Panel, navigation bar, timer notifications, and the Routines app. Additionally, it includes the security patch level dated July 5, 2026.
One UI 9 is set to make its official debut on the Galaxy Z Fold8, Fold8 Ultra, and Flip8, all of which are expected to launch later this month. The official announcement is scheduled for July 22. Subsequent updates for older devices will follow.
