Samsung starts testing One UI 9.5 on Galaxy S27, S27+, S27 Pro, and S27 Ultra: Report
Samsung has reportedly started testing One UI 9.5 firmware on four Galaxy S27 models, scheduled to be released in the first quarter of next year.
Galaxy S lineup usually had three flagship models until 2026. Meanwhile, Samsung plans to expand the range further by adding a new Pro variant. That said, there will be a total of four flagship phones in next year’s Galaxy S series.
As spotted by TarunVats, Samsung has “started internal testing” of One UI 9.5 for the Global/European versions of the Galaxy S27 series. The firmware builds have also revealed model numbers, which align with related leaks.
- Galaxy S27 (SM-S952B)
- Galaxy S27+ (SM-S956B)
- Galaxy S27 Pro (SM-S957B)
- Galaxy S27 Ultra (SM-S958B)
Samsung initially planned impressive upgrades for the Galaxy S27 Pro. However, increasing component costs have changed the dynamics. Now, the Galaxy S27 Pro is getting ready as a balanced flagship model.
Galaxy S27 Ultra may also skip the Variable Aperture camera. That said, the flagship phone will continue to rely heavily on software tricks. Samsung is ignoring the tech despite Apple’s set to launch the iPhone 18 Pro with variable aperture.
Recently, a Galaxy S26 was spotted running One UI 9.5 firmware. The initial set of leaks revealed a native App Lock feature for Galaxy devices. We will have even more early impressions of the upcoming software over the period.
Presently, Samsung is focusing on the sales of its newly released foldable phones. The Galaxy S26 FE is planned to be announced early next month. We can expect the stable One UI 9 rollout to commence after the FE debut.

One UI 9.5 looks clean and modern with new design tweaks – Check it out
Samsung is working on One UI 9.5 ahead of the One UI 9.0 rollout, and an early look at the software running on the Galaxy S26 has revealed some interesting changes. The update does not completely change the look of One UI, but it brings several small improvements that make the interface look cleaner and more modern.
As per the screenshots shared by tipster Fahad Ali Javed, the main change is the use of subtle background shading. You can see this effect behind home screen widgets, bottom navigation bars, and buttons at the top of the screen. These small shadows and shades help separate different parts of the interface.
The new design gives the screen a little more depth. Instead of everything looking flat, different sections are easier to see and understand. The changes are simple, but they make the overall experience feel more polished.

Samsung is also adding a new Search feature inside the Dialer app. This feature can use Samsung’s AI technology to help users find information, similar to how Samsung Finder works. With this new search option, users may be able to find contacts, phone numbers, and other related information more easily.
One UI 9.5 looks like an improvement update rather than a major redesign. Samsung seems to be focusing on small details that can make a big difference in everyday use.
Notably, Samsung hasn’t confirmed anything yet about One UI 9.5. We can expect new AI features and major improvements in the final version. Stay tuned.

Here’s your first look at Samsung One UI 9.5 with App Lock feature
Samsung has yet to start a stable One UI 9.0 rollout for Galaxy devices, but someone has already installed One UI 9.5 on a Galaxy S26. The internal One UI 9.5 update comes with several changes, including a fully functional App Lock feature.
One UI 9.0 debuted on Samsung’s Z8 series phones. The company will unveil One UI 9.5 with the Galaxy S27 series next year. A Beta Program is expected later this year, but FahadAliJaved is already rocking the latest software.
Galaxy S26 One UI 9.5 has several changes
The screenshots posted on X reveal crucial information about the device and its software. The One UI 9.5 CZH9 build has been installed on Galaxy S26 (SM-S942B).
The update screen showed a One UI 8.5 banner, while the setup page is also familiar. Samsung preserved the aesthetics on these segments for now, but major changes are likely in future builds.

It shows Android version as “CinnamonBun,” which is the internal dessert codename for Android 17. Moreover, the Google Play System update is dated “1 October 2026,” a build that will generally release in October or November.
App Lock is here in and it’s fully functional
One UI 9.5 may finally introduce a native App Lock feature to Samsung devices. The leaked firmware comes with a functional App Lock.
Pressing and holding on an app icon shows a button to safeguard the app. Its setup screen reveals how it works and the potential impacts of locking an app on your device.
To open a locked app, you need to verify your identity with biometrics or your screen lock PIN, pattern, or password.
When an app is locked:
-
- Widgets and shortcuts are removed on your Home screen.
- Notification content is hidden.
However, your photos, videos, contacts, and other data will still be accessible to apps that already have access.

Fifth One UI 9 Beta is unexpectedly disappointing
Samsung recently released the fifth One UI 9 Beta update for the Galaxy S26 series. However, the update is unexpectedly disappointing, as it brings no major changes or new features.
Notably, One UI 9 Beta 4 was released in mid-July 2026, while Beta 5 arrived almost a month later. Due to the long gap between the two updates, users were expecting Samsung to bring some important improvements and new features with the latest beta.
Unfortunately, One UI 9 Beta 5 only fixed problems found in the previous beta versions. These fixes are important because they can make the software more stable and reliable. However, users were also expecting Samsung to add some of the new features to the Galaxy S26 series that are already available in the official One UI 9 version.
The lack of these features is one of the biggest disappointments with Beta 5. After waiting for almost a month, many users expected the latest beta to be a bigger update.
Samsung may have another plan for the upcoming beta versions. The company could introduce the missing features with One UI 9 Beta 6 before releasing the stable version. This would give Samsung more time to test the features and fix any problems before the final rollout.
At the moment, One UI 9 Beta 5 feels more like a small maintenance update than a major beta release. It improves the software by fixing existing problems, but it does not offer much that feels new. Still, there is hope that Samsung will bring more changes in the next beta or with the stable update.

Stable One UI 9.0 could be the next Galaxy S26 series update
Samsung may soon release the stable One UI 9 update for the Galaxy S26 series. The company recently rolled out the One UI 9 Beta 5 update, and new information suggests that the stable version could be the next major update.
According to tipster Kailash, a possible stable One UI 9 build for the Galaxy S26 series has been spotted. The new firmware build has been spotted as S948BXXU4BZH8. The reported change is from the ZZH6 beta build to the BZH8 stable build.
This could be an important hint that Samsung is close to finishing the One UI 9 Beta testing program. It means that One UI 9 Beta 5 could be the final beta update for the Galaxy S26 series.
Samsung usually releases several beta updates to find and fix bugs before launching a stable version. With Beta 5 already available, the company may now be working on the final changes and preparing the stable update for users.
However, Samsung has not officially confirmed the One UI 9.0 rollout yet. The company could also make more changes or release another beta if it finds important issues during testing.
This new stable build suggests that the One UI 9 stable update could be getting closer. At the moment, there is no official release date for the stable One UI 9 update rollout. Therefore, users should take this information as a leak and not official confirmation. Stay tuned for more information.

Good news: Galaxy S24 flagships to join One UI 9 Beta Program
Samsung has reportedly widened the scope of its One UI 9 Beta Program, gearing up the software for its 2024 flagship lineup, the Galaxy S24 series.
One UI 9 Beta is exclusively available on the Galaxy S26 series. However, the exclusivity will end soon as the Galaxy S25 series and Galaxy S24 series flagships are preparing to join the One UI 9 Beta Program in the near future.
In a recent development, tech enthusiast FahadAliJaved discovered the ZZH8 build for Samsung’s SM-S928B. The model number and internal build versions give us a glimpse of the future software update rollout.
- SM-S928B is the Galaxy S24 Ultra’s Global variant.
- ZZH8 is a Beta build, potentially the One UI 9 Beta.
Earlier, the public Beta builds were surfaced for the Samsung SM-S938B (Galaxy S25 Ultra) variant. 2025’s flagship lineup will be ahead of its predecessors in joining the Beta testing activity, which is expected to start very soon.
One UI 9 status across Galaxy S flagships
- Galaxy S24 Ultra (SM-S928B) – First Beta build spotted
- Galaxy S25 Ultra (SM-S938B) – A new Beta build spotted
- Galaxy S26 Ultra (SM-S948B) – New Stable build spotted
- Galaxy S23 Ultra (SM-S918B) – Internal Stable build spotted
Yesterday, Samsung dropped the fifth One UI 9 Beta for the Galaxy S26 series. This is the first Beta update to land after the official release of One UI 9. Meanwhile, it was very disappointing as it doesn’t carry any new useful features.
Samsung is testing a new Stable build for the Galaxy S26 series. However, the company is less likely to begin the official update rollout this month. The testing may be stretched further, and we expect it to last until mid-September.
