Samsung has released the fourth One UI 9 beta for the Galaxy S26 series, bringing another round of bug fixes and refinements ahead of the software’s official debut later this month.
The update has started rolling out in India first, carrying firmware that ends in ZZG4, and is available to users already enrolled in Samsung’s One UI 9 beta programme. At around 1.25GB, it’s a sizeable download.
Rather than introducing major new features, this latest beta focuses on stability as Samsung enters the final stretch before launch. According to the changelog, the company has fixed a range of issues affecting core parts of the interface. These include problems with the clock size, Quick Panel, navigation bar, timer notifications, and the Routines app.
The update also bundles the July 5, 2026 Android security patch, ensuring testers receive the latest security fixes alongside the software improvements.
The timing isn’t particularly surprising. Samsung has been steadily polishing One UI 9 over the past few months. The third beta arrived almost exactly a month ago. Consequently, a fourth beta at this stage suggests the company is ironing out the remaining rough edges before making the software widely available.
One UI 9 is expected to make its official debut alongside Samsung’s next generation of foldables at Galaxy Unpacked on 22 July. At that event, the company is expected to unveil the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and Galaxy Z Flip 8. Those devices will be the first to ship with the new software out of the box, with older Galaxy smartphones and tablets getting it in due course.
While Samsung hasn’t confirmed whether another beta will follow, this release suggests the software is approaching its final form.
As with previous beta releases, availability remains limited to registered participants in supported regions. However, the rollout will likely expand gradually. Galaxy S26 owners enrolled in the programme should see the update appear over the air in the coming days if it hasn’t already reached their device.
