Google unveiled new security and privacy features for its Android platform, focusing on safeguarding calls, screen sharing, messages, device access, and system-level permissions. Key measures include blocking unsafe actions during calls with unknown contacts, restrictions on side-loading apps from unverified sources, and limiting accessibility permissions to prevent scams. Users on Android 6 or later will not be able to disable Google Play Protect, which scans for harmful applications. Enhanced screen-sharing protection includes reminders to stop sharing after calls and a warning screen for banking apps when sharing with unknown numbers. Google Messages will improve scam detection using on-device AI for various fraud types. Verification keys in the Google Contacts app will allow users to authenticate contacts, with end-to-end encryption for verified conversations. Identity Check protection requiring biometric authentication will be extended to more devices, and stricter controls on Factory Reset functions will be implemented. Google is also enhancing its Play Protect program to detect unsafe apps and strengthening Advanced Protection Mode for public figures, along with introducing a new Find My Hub feature.
