Android 17 to Feature Built-in App Lock for Enhanced Privacy

Google is rolling out a new privacy feature for Android 17 that will allow users to lock individual applications directly within the operating system. This built-in App Lock function aims to prevent accidental privacy breaches when lending phones to friends or family.

Previously, users had to rely on third-party applications to secure specific apps. With Android 17's QPR2 Beta 3 update, users can now find a "Lock App" option in the menu that appears when long-pressing an app icon. This allows for easy locking of sensitive applications like messaging apps, chat histories, or photo galleries.

Once an app is locked, it will require fingerprint or PIN verification before opening. This ensures that others cannot access private information such as banking details, text messages, or chat logs. Additionally, notification content for locked apps will be hidden, preventing sensitive information from being exposed on the lock screen or notification bar. Even app shortcuts and widgets will disappear when locked.

The App Lock feature is expected to be available on Pixel 6 and newer models when Android 17 QPR2 launches in December. Other manufacturers, including Samsung, will gradually roll out the feature according to their own system update schedules.
