Samsung has started rolling out One UI 9 Beta 3 for the Galaxy S26 lineup, and the update is drawing attention largely because of its size. At around 1.8GB, it is one of the largest beta packages released for the Galaxy S26 series so far.
The build, which ends in ZZF7, is available only to Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra units enrolled in the beta program in supported markets. Rather than focusing on headline features, Samsung is using this release to clean up the issues that have affected daily use the most.
Focus on stability, not new features
The update is centered on bug fixes, system stability, and overall refinement. That approach is typical of a late beta cycle, when the priority shifts from adding functions to making the software reliable enough for the final release.
For users following One UI 9 development, the size of the download suggests that Samsung has bundled a broad set of fixes into a single package. It also indicates that the company is moving quickly to mature the software before the stable version arrives.
Several visible bugs are being addressed
One of the most notable fixes concerns Privacy Display, but only on the Galaxy S26 Ultra. Samsung said the feature could behave incorrectly when used with routines or when settings were changed through the Quick Panel.
The camera app is also getting attention. Samsung has fixed a problem that could cause part of the viewfinder to appear cut off, which is the kind of issue that can immediately affect everyday photography.
Lock screen widgets are included in the cleanup as well. Weather information and battery status should now refresh more reliably, reducing one of the more frustrating beta-era annoyances.
Photography performance has also been adjusted. Samsung says focus accuracy has been improved when using the 30x zoom camera, a detail that should matter to owners who use the Galaxy S26 Ultra’s telephoto capabilities often.
Support for the S Pen has not been ignored either. A bug that could prevent users from swiping between home screen pages while using the stylus has been fixed in this build.
My Files is another app that received a correction. Samsung addressed an issue that kept long file lists from scrolling all the way to the bottom, which makes the file manager more usable in practical scenarios.
Visual glitches and unexpected reboots are also fixed
Beyond feature-specific problems, the beta tackles broader system issues. Samsung says users should no longer see random white backgrounds when incoming calls arrive.
The company has also dealt with an unexpected reboot issue that could happen while streaming video. Fixing a problem like that is especially important in beta software, where stability is often the clearest measure of progress.
Another visual glitch has been removed as well. A black background that could appear incorrectly when pulling down the notification panel has been corrected, helping make routine interactions feel more consistent.
Taken together, the changes in One UI 9 Beta 3 suggest that Samsung is concentrating on the complaints that beta testers are most likely to encounter in daily use. The update does not promise a major feature wave, but it does appear designed to remove the rough edges that could stand in the way of a stable final release.
Samsung has already made the build available to eligible beta users in supported regions, and more beta releases are still expected before the stable version arrives later this year. For Galaxy S26 users in the program, this update is less about surprises and more about making the software feel finished.
