Samsung Galaxy phones may soon get a long-awaited privacy upgrade with One UI 9.5, and it could make everyday app security much easier. A new App Lock feature has appeared in a current One UI 9.5 test build, giving users the option to protect individual apps using their regular phone unlock method, such as a password or fingerprint.
App Lock is already familiar to many Android users on devices from other brands, but Galaxy owners have been waiting for a more direct, built-in version. With this feature, users would be able to lock sensitive apps like email, messaging, banking, photos, or work tools without needing a separate third-party app. In the test example, Outlook is shown as a locked app, suggesting the feature could work across a wide range of installed apps.
This could be especially useful for people who share their phone with family members, hand their device to someone briefly, or simply want an extra layer of privacy. Instead of locking the entire phone again and again, specific apps can be protected individually. If someone opens a locked app, the phone would require authentication before showing its contents.
One UI 9.5 also appears to bring a refreshed visual style to Galaxy smartphones. The interface changes are not dramatic, but they point toward a cleaner and more modern design direction. Several elements now seem to use a more polished glass-like appearance, with subtle depth and a slightly more three-dimensional look.
The updated design can be seen in areas such as the brief widget, the dialer search bar, and the system sound volume control. These changes suggest Samsung is refining the overall One UI experience rather than completely replacing it. The result could be an interface that feels more premium while still remaining familiar to existing Galaxy users.
Some smaller layout adjustments are also visible. For example, certain icons have been moved, including the search icon in the phone app. These changes may seem minor, but they can affect how quickly users find important tools during daily use.
If App Lock launches with One UI 9.5, it could become one of the most practical new Galaxy features in the update. Privacy and security are major priorities for smartphone users, and built-in app protection would give Samsung Galaxy owners more control over their personal data.
The combination of stronger app privacy and a more refined interface suggests One UI 9.5 could be a meaningful update for current Samsung phones. While the design changes remain subtle for now, the new App Lock feature may be the upgrade many Galaxy users notice and use the most.
