Android System SafetyCore app has been appearing on Android phones without user explanation or choice, causing concerns among users.
The app uses machine learning to analyze images locally and applies blurring if it detects suggestive content, but Google assures that no scan results are sent anywhere.
The SafetyCore app is designed to be called upon by other apps and is initially available only in Google Messages, with plans to expand to other messaging apps in the future.
Another app, Android System Key Verifier, is also automatically installed on devices, allowing users to securely verify keys during end-to-end encrypted messaging.
