Google’s upcoming Android 17 update is set to deliver a major privacy upgrade, allowing users to lock apps behind device security and hide message content from notifications on Pixel, Samsung, and other Android phones.
The update expands on Google’s new App Lock feature, which lets users secure individual apps using a PIN, fingerprint, or face unlock—without relying on third-party tools or Android’s more complex Private Space option.
According to Android Authority, early Android 17 test builds show that locked apps will no longer display notification content. Instead, alerts will show generic text such as “New message” or “New notification.”
This change is designed to prevent sensitive information from appearing on lock screens, even if someone can see incoming notifications. Message senders and content will remain completely hidden.
The feature is especially important for messaging apps, where private conversations can easily be exposed. Apps like WhatsApp already offer similar protections, but Android 17 will now make this system-wide and consistent.
Google plans to mask notifications differently based on app type. Messaging apps will show “New message,” while non-chat apps will simply display “New notification,” offering no clues about the content.
Security experts say this update could significantly reduce accidental data leaks, especially when phones are shared, misplaced, or viewed in public spaces.
The move brings Android closer to Apple’s iOS 18, which already includes native app-locking features, and marks a strong step forward in Android privacy and user control.
