Samsung appears to be working on the next iteration of its Galaxy software, with Samsung One UI 9.5 now running on a Galaxy S26 in an early internal build. The software offers an early look at features Samsung could introduce in its next major One UI update, including a native App Lock option that would allow users to protect individual applications directly.
The development comes while Samsung is still rolling out One UI 9 based on Android 17. The early One UI 9.5 build also points to changes in the visual design of parts of the interface, suggesting Samsung is already testing the next stage of its software experience. Samsung has yet to officially announce the update.

Native App Lock Could Bring a Major Privacy Change
The most notable feature emerging with One UI 9.5 is native App Lock, which could make it easier for Galaxy users to protect individual applications. Rather than placing an application inside Samsung’s separate Secure Folder environment, users could reportedly lock it directly from the Home screen or app drawer. The feature can be accessed by pressing and holding an application icon and selecting the lock option.
Once enabled, opening the protected application requires the user to verify their identity using biometrics or the phone’s existing PIN, pattern or password. This could give users a more direct way to protect applications containing sensitive information, such as messaging, banking, gallery or social media apps.
Locked Apps Hide Notifications and Shortcuts
One UI 9.5’s reported App Lock implementation goes beyond simply requiring authentication before an application opens. When an app is locked, its notification content is hidden, reducing the possibility of private information appearing in notifications. The system also removes the locked app’s widgets and shortcuts from the Home screen.
However, locking an app does not completely isolate its data from other applications. Apps that already have permission to access information such as photos, videos or contacts can reportedly continue accessing that data. The distinction is important because App Lock is primarily designed to restrict direct access to the application itself rather than functioning as a complete data-isolation system.
One UI 9.5 Brings Visual Refinements
Alongside App Lock, the early software points to a subtle change in Samsung’s interface design. Certain elements are reportedly receiving a glass-inspired appearance, with translucent layers and softer visual separation. The software update screen has also been redesigned with rounded floating cards, pill-shaped controls and more layered interface elements.
The update banner itself uses a different visual treatment from earlier One UI versions. These changes do not indicate a complete redesign of One UI, but they suggest Samsung could be experimenting with a more modern visual language for the next software release. Since the software is still under development, the final design could change.
Android 17 and Build Details
The early firmware is based on Android 17, with “CinnamonBun” appearing in the software information. The build is identified as S942BXXU4CZH9 on the Galaxy S26 model SM-S942B. The available update information also lists a package of 4568.58MB, or approximately 4.56GB. This represents the size shown for the early build and should not be treated as the final download size for the eventual public One UI 9.5 release.
The appearance of the software on a Galaxy S26 indicates that Samsung is already testing One UI 9.5 internally, even though One UI 9 is still the current major software generation being prepared for wider rollout.
What One UI 9.5 Could Change for Users
If Samsung retains the App Lock feature for the final release, it could provide Galaxy users with a simpler privacy option than relying exclusively on Secure Folder. Locking an application directly from the Home screen and using the phone’s existing authentication system could make protecting individual apps faster and more convenient.
Hiding notification content and removing associated widgets and shortcuts could also prevent some private information from being exposed while the application remains locked. However, users should not assume that every feature currently found in the early build will reach the final version. Samsung can modify or remove features during development and testing.
One UI 9.5 Release Timeline
Samsung has not announced an official release date for One UI 9.5. Current reports suggest the software could debut with the Galaxy S27 series, potentially in early 2027, while a beta version for existing Galaxy devices could arrive earlier. These timelines remain unconfirmed. For now, the early Galaxy S26 build provides the clearest indication that Samsung is actively developing the next One UI version. More features and design changes could emerge as additional builds become available.
Conclusion
Samsung’s One UI 9.5 is shaping up to bring a more direct privacy option through native App Lock, alongside Android 17 and visual refinements to the Galaxy interface. The early build also suggests Samsung is testing broader changes to how applications and system screens look and behave. However, One UI 9.5 remains unannounced by Samsung, meaning its final features, eligible devices and release schedule could still change before the public rollout.
