Android 17, expected to start testing on Pixel devices later this year, is set to introduce a long-requested privacy feature, App Lock. Samsung users will see a similar update with One UI 9, which is scheduled to launch alongside the Galaxy Z Fold 8 in the second half of 2026.
App lock built into the OS
Leaked images from an internal Android 17 build, also known as Baklava, reveal that Google is adding app-level protection directly into the operating system. Users will be able to lock individual apps by long-pressing their icons on the home screen. Access will require the device’s screen lock credentials, such as a PIN, pattern, or biometric verification.
The leak also shows improvements to notification handling. When an app is locked, sensitive content such as messages can be hidden, while still indicating that a notification has arrived. This allows users to keep their information private without missing important alerts.
How it compares to Samsung’s secure folder
Samsung already offers a privacy tool called Secure Folder, which is encrypted and feature-rich. However, Secure Folder requires moving apps into a separate vault and managing duplicates, which some users find cumbersome.
In contrast, the Android 17 App Lock is lightweight and integrated directly into the home screen. It is designed to make locking apps like messaging, galleries, or finance tools simpler and quicker, without additional setup or duplicate apps.
Looking ahead
Android 17 is expected to roll out for testing on Pixel devices before wider release. One UI 9, based on Android 17, will follow on Samsung devices later in the year, starting with the Galaxy Z Fold 8. Both updates aim to offer users more control over their privacy while keeping everyday use straightforward.
