Google Unveils Advanced Android Security Features to Combat Scams and Theft

Google has announced a comprehensive suite of new security and privacy features for Android devices, aiming to protect users from scams, unauthorized access, and device theft. These enhancements were revealed ahead of the Google I/O event and target multiple vectors of attack including phone scams, malicious apps, and unauthorized screen sharing.

Enhanced Scam Protection During Calls

To combat phone scams, Google is blocking risky actions and warning users when receiving calls from unknown numbers. For example, Android 16 prevents side-loading apps from unverified sources during calls and restricts granting accessibility permissions that could allow scammers to control devices. Additionally, Google Play Protect cannot be disabled on devices running Android 6 or later while on a call, ensuring continuous protection.

Screen Sharing Safeguards

Google is introducing screen-sharing protections that remind users to stop sharing after a call ends. In partnership with select UK banks, Android 11+ devices will display warning screens if users share their screen with unknown parties while using banking apps, offering a quick option to end the session and prevent fraud.

Advanced Messaging Scam Detection

Building on its March launch, Google Messages now uses on-device AI to detect a broader range of scams including crypto fraud, gift card scams, and financial impersonation. Verification keys in Google Contacts enable users to authenticate contacts via QR codes or matching numbers, protecting against SIM swap attacks and ensuring end-to-end encrypted conversations.

Robust Theft Protection Features

Google expanded its Identity Check protection to more devices with Android 16, requiring biometric authentication to change critical settings or disable theft protection outside trusted locations. Factory Reset protections will restrict unauthorized resets without prior credentials, making stolen devices harder to repurpose. Additionally, security challenge questions and OTP hiding features enhance device security further.

Additional Security Enhancements

Google Play Protect’s live detection will soon identify apps with hidden or altered icons on Pixel 6+ devices, applying new on-device rules to catch more malicious apps. Advanced Protection Mode receives new features to safeguard public figures, and the new Find My Hub helps users track items, friends, and family, enhancing overall device security and user privacy.

These updates reflect Google's commitment to evolving Android’s security architecture to meet emerging threats. By integrating AI-driven scam detection, biometric safeguards, and enhanced app vetting, Google empowers users and developers with tools to maintain device integrity and privacy in an increasingly complex threat landscape.
