Google has begun actively testing the App Lock feature at the system level. This capability was discovered in the code of the Android 17 QPR2 Beta 3 preview version. This means users will no longer have to rely on third-party solutions or complex "Private Space" settings to protect sensitive data. ### How the new App Lock feature works According to data from 9to5Google, the new feature is already available on Pixel devices participating in the beta testing program. The implementation is intuitive: to activate protection, the user simply needs to long-press the icon of any app, after which the "App Lock" option will appear in the context menu. Once configured, access to the selected app will only be possible after entering a password, PIN, or passing biometric authentication (fingerprint or Face ID). An important difference from previous versions of Android is that the function works at the operating system level. This ensures universality: any installed apps are subject to locking, regardless of whether they are developed by Google, third-party companies, or are system utilities. ### Enhanced privacy: hiding notifications and widgets Google has thought out protection not only from direct access to the app but also from information leaks through the interface. When App Lock is activated, the system automatically disables the preview of content in notifications. This is critical for messengers like WhatsApp or Telegram: if the phone is locked, the text of incoming messages will remain hidden until the user unlocks the app itself. Furthermore, the function blocks the display of content on widgets and dynamic shortcuts associated with the protected app. For example, an email widget will not show email subject lines, and a notes widget will not show their content. The only exception is AI agents: if the user previously granted them permission to access data, AI services will continue to work with the information even when the app is locked. ### Release timeline and support for third-party brands Although the feature is already working on beta devices, it will not be available to the general audience immediately. The final version of Android 17 QPR2 is likely to be released in December 2026. This is the standard schedule for major Android updates, which go through several stages of testing before release. However, the Android ecosystem is not limited to Pixel devices only. Similar capabilities have already been discovered in the beta version of the Samsung One UI 9.5 firmware, which is based on Android 17. This indicates that the Korean giant is ready to integrate native app locking into its smartphones. Nevertheless, deploying the feature on millions of Samsung devices will likely take longer than for Google due to the need for careful adaptation of the One UI interface. ### Evolution of protection: from Private Space to targeted locking Previously, Android had a "Private Space" feature that allowed users to create an isolated environment for certain apps. However, this method was cumbersome and required switching between profiles. The new App Lock feature offers a much simpler and faster solution, allowing users to protect specific apps within the main home screen. This makes Android 17 more competitive compared to iOS 18, where a similar feature has already become the standard for protecting user privacy. ## πŸ” Fact-Check Verification - [Google starts testing app locking at the Android system level window-new](https://3dnews.ru/1147018/google-nachala-testirovat-blokirovku-prilogeniy-na-urovne-android) - Основной источник ΠΈΠ½Ρ„ΠΎΡ€ΠΌΠ°Ρ†ΠΈΠΈ ΠΎ появлСнии Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ Π² Android 17 QPR2 Beta 3. - [Android finally learned to lock apps from prying eyes](https://news.rambler.ru/tech/56873890-android-nakonets-to-nauchilsya-zakryvat-prilozheniya-ot-postoronnih/) - ΠŸΠΎΠ΄Ρ‚Π²Π΅Ρ€ΠΆΠ΄Π΅Π½ΠΎ ΠΏΠΎ источнику news.rambler.ru - [Leaving your phone unattended on the table?
