Samsung is moving quickly through its software testing cycle, and the One UI 9 Beta 4 release date is now expected to land around June 30 for Galaxy S26 series owners enrolled in the program. The company has maintained a consistent two-week cadence between each beta build since May, and with Google’s Android 17 now finalized, that pace shows no signs of slowing. Here is a detailed look at the current status of One UI 9 development and the devices involved in testing.
Samsung Prepares the Next One UI 9 Beta Update
Samsung’s public beta timeline for One UI 9 has been precise. The company released Beta 1 on May 13, Beta 2 on May 26, and Beta 3 on June 16. If that pattern continues, the One UI 9 Beta 4 release date falls squarely around June 30, giving Samsung roughly two weeks between each update.
The One UI 9 beta 4 rollout applies to Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra owners in six countries: the United States, the United Kingdom, Germany, India, South Korea, and Poland. Users not yet enrolled can register through the Samsung Members app. Those already in the program will receive the update through the standard software update pathway.
To verify whether a Samsung One UI 9 update is available, users can open Settings, navigate to Software Update, and select Download and Install. Samsung has not pinpointed an exact date, so checking back periodically as June 30 approaches is the most reliable approach.
One UI 9 is progressing faster than One UI 8.5, which went through a longer beta testing cycle before reaching a stable release. One UI 9 is on a tighter schedule, and the reasons for that shift come down largely to external factors — primarily the state of Android 17.
What Beta 3 Fixed for Galaxy S26 Users
Before the One UI 9 Beta 4 release date arrives, it helps to understand what the previous build delivered. Beta 3 for the Galaxy S26 One UI 9 beta brought a meaningful round of fixes targeting stability and core functionality.
Camera and Playback Repairs
Camera performance was among the highest-priority areas addressed. Beta 3 corrected camera zoom behavior, fixed camera preview display issues, and resolved a cropping problem that had been affecting the camera preview. These fixes addressed several camera-related issues reported in earlier beta builds.
Lock screen widget refresh errors were also eliminated, alongside a bug affecting the Privacy Display feature. Galaxy S26 Ultra users in the Galaxy S26 One UI 9 beta received a specific correction as well: S Pen home screen swipe behavior that misbehaved in earlier builds has now been addressed.
One of the more disruptive bugs was also resolved in Beta 3. Random reboots occurring during video streaming were causing unexpected interruptions, and Samsung prioritized that fix for this build.
One issue that remains outstanding is a visual regression affecting the Finder icon, reported by users in the Beta 3 build. Samsung is expected to address it in the One UI 9 beta 4 rollout, though no formal confirmation has been issued.
How Android 17 Is Helping Samsung Move Faster
The accelerated One UI 9 Beta 4 release date is not solely a product of Samsung’s internal planning. A critical external factor is Google’s decision to release the stable version of Android 17, giving Samsung a finalized platform to build on.
During earlier stages of development, Samsung had to run its testing while anticipating potential changes from Google’s side. Now that the Android 17 stable release is complete, that uncertainty is gone. Samsung can focus its testing resources on its own code rather than managing shifting platform dependencies.
The Android 17 stable release brings several technical changes that feed directly into the Samsung One UI 9 update. Google redesigned the garbage collection system within the Android Runtime — known as ART — with the goal of reducing interface stutter, cutting power consumption, and improving raw performance across devices.
The Android 17 stable release also raises the bar for large-screen device support. Apps targeting API level 37 are now required to adapt their interfaces to larger displays, including foldables. That requirement has clear relevance for Samsung, which ships phones across a wide range of screen sizes.
The One UI 9 features being built on this foundation reflect a deliberate approach. The Samsung One UI 9 update is not pursuing a visual overhaul. Instead, it concentrates on accessibility improvements, security enhancements, and performance optimizations tied to Android 17. That narrower scope contributes directly to the faster pace of testing.
Which Devices Are Part of the One UI 9 Testing Cycle
The Galaxy S26 One UI 9 beta is the furthest along in the public testing pipeline, but Samsung is running development work across four flagship generations simultaneously.
Public Beta Devices
The Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra are the devices currently receiving public beta builds. The One UI 9 Beta 4 release date of approximately June 30 applies to this group. Users already enrolled will receive the build automatically; new enrollments are processed through the Samsung Members app.
Internal Testing Devices
Firmware tracker Tarun Vats confirmed that internal One UI 9 testing has started for the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and Galaxy S25 Edge. The Galaxy S25 series is described as next in line for the public beta, meaning public access could open shortly around the time of the One UI 9 Beta 4 release date.
Internal builds have also been confirmed for the Galaxy S24 One UI 9 program. The Galaxy S24, Galaxy S24+, Galaxy S24 Ultra, and Galaxy S24 FE are all included in the testing pool. Galaxy S23 One UI 9 development is underway as well, with the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra all part of the internal pipeline. An early internal build for the Galaxy A56 has been spotted, extending Samsung’s testing reach into the mid-range segment.
Running internal builds across four generations of flagships and a mid-range device at the same time reflects Samsung’s commitment to a fast turnaround for the Samsung One UI 9 update across its lineup.
Devices Shipping With One UI 9
Three devices will arrive running One UI 9 pre-installed from launch: the Galaxy Z Fold 8 Ultra, the Galaxy Z Fold 8, and the Galaxy Z Flip 8. All three are expected to debut at Samsung’s Galaxy Unpacked event, where the One UI 9 stable rollout is also expected to be announced.
Expected Timeline for Stable One UI 9 Release
Reports suggest Samsung’s Galaxy Unpacked event is planned for July 22. The One UI 9 stable rollout is expected to coincide with that date, with the Galaxy Z Fold 8 series and Galaxy Z Flip 8 serving as the first devices to run a completed build in consumers’ hands.
For Galaxy S26 users currently in the beta program, the stable One UI 9 rollout would follow the Unpacked event. Samsung typically stages its software releases, starting with the most current flagships and working outward from there. Galaxy S26 software update recipients could see the stable build arrive shortly after the foldable launch, with older device families following in subsequent weeks.
The One UI 9 features already visible in beta builds — accessibility improvements, privacy tools, security updates, and Android 17 performance gains — represent the bulk of what the stable release will contain. One headline capability, however, has not appeared in any public beta build to date.
What Users Can Expect Next
The One UI 9 Beta 4 release date of around June 30 positions Samsung close to the final stretch before the stable launch. If the build lands on schedule, Samsung could move closer to the stable rollout expected next month.
One feature that has not yet appeared in the public beta is Gemini Intelligence. Described as agentic AI, this feature handles multi-step tasks without requiring continuous user input. Specific capabilities reported include booking concert tickets with minimal manual involvement, pulling items from a Notes app and placing them directly into an Amazon cart, and reviewing emails while drafting replies.
Gemini Intelligence does not currently appear in the Galaxy S26 One UI 9 beta. It is expected to debut with the Galaxy Z Fold 8 in July, timed to the Unpacked event and the stable One UI 9 rollout.
For testers awaiting the One UI 9 beta 4 rollout, the next build should bring additional stability improvements and, based on reported issues, a fix for the outstanding Finder icon regression. Users can monitor Galaxy S26 software update availability through Settings or by checking the Samsung Members app for program announcements as June 30 approaches.
For those on devices currently in internal testing — whether the Galaxy S24 One UI 9 track, the Galaxy S23 One UI 9 track, or the Galaxy S25 series — public beta access remains the next milestone. How quickly Samsung opens registration for those models will depend on the stability of the One UI 9 Beta 4 release and how close the company is to finalizing its build ahead of the July Unpacked event.
