Samsung is reportedly preparing to introduce a native App Lock feature in its upcoming One UI 9 update. This new function will enable users to lock individual apps directly on their Galaxy devices without requiring additional third-party applications. The feature leverages a new security capability currently under development in Android 17, which promises to enhance privacy and control over app access.
Until now, Samsung users have had to rely on the Secure Folder or external apps to restrict access to sensitive applications. This contrasts with Apple, which has offered built-in App Lock functionality in iOS for several years. The absence of a native lock feature in One UI has been a notable gap, despite the interface’s reputation for rich customization and flexibility.
Insights from Android 17 Canary Build
Key clues about the upcoming App Lock feature come from the Android 17 Canary build, which Google recently released for testing. In this experimental version, notifications from locked or hidden apps display generic messages rather than revealing any private content. For example, messaging apps show “New message” instead of the actual message details, while other apps simply display “New notification.”
This behavior suggests that Android 17 includes a system-level mechanism to secure apps by obscuring their notifications and controlling direct access. Although Google has yet to officially confirm or detail this App Lock feature, Samsung appears poised to incorporate it into One UI 9 once Android 17 is finalized.
Samsung’s Strategy of Waiting on Android Foundation
Samsung has historically preferred to build its major system features on the core capabilities provided by Android. A recent example is the integration of Samsung DeX with Android 16’s Desktop Mode, replacing Samsung’s earlier proprietary solution. This approach ensures deeper system integration and improved stability.
The same pattern is expected for the App Lock launch in One UI 9. By adopting Android 17’s native app locking tools, Samsung can deliver a more seamless and secure user experience. This also allows Samsung to avoid potential conflicts or bugs that arise from external locking methods or add-on apps.
Potential Benefits for Galaxy Users
The availability of native App Lock is set to significantly enhance privacy protections for Galaxy users. They will be able to lock sensitive apps such as banking, gallery, and messaging apps using biometrics or PIN codes, all without moving data into the Secure Folder. This change simplifies app management and improves convenience.
Moreover, the feature’s ability to obfuscate notifications minimizes the risk of data leakage in public spaces. Users can confidently receive updates without exposing confidential information on their lock screen or notification panel.
Expected Timeline and Rollout
Industry sources anticipate Google will officially unveil Android 17 in the second half of this year. Shortly thereafter, Samsung is likely to begin beta testing One UI 9 on its latest Galaxy smartphone and tablet models. The inclusion of App Lock could be one of the major highlights of that update.
While Samsung has not formally confirmed the App Lock feature, the signs from Android’s development cycle and Samsung’s recent update history strongly indicate it is imminent. Galaxy users can expect enhanced on-device security features that no longer depend on third-party apps, marking a new chapter in Samsung’s privacy offerings.
