Android smartphones will gain a feature to detect spoofed calls, allowing them to verify, based on RCS (Radar Call Standard), whether the caller is actually making the call from the phone app.

To combat scams where callers impersonate people users know, Google has added a 'Fake Call Detection' feature to Android smartphones. This feature detects whether the caller is using Google's phone app, 'Phone by Google.'

Android introduces fake call detection to stop deepfake scams

WHOA @Google let me know they saw my tweet below last year & built a tool to defend against this exact call spoofing + AI voice clone attack!
As of today, fake call detection on Android alerts when someone is impersonating your contact.

According to Google, because users have stopped answering calls from unknown numbers in recent years, scammers are using tools to impersonate existing numbers. This makes it difficult for users to detect the scam, as it appears to be a genuine call from someone they know, and in some cases, AI is used to impersonate them.

Google's spoofing call detection feature detects whether the person you're calling is using Phone by Google and warns you if they're using any other tool. The mechanism works by having Phone by Google send a silent confirmation signal to the caller when a call comes in. If the caller doesn't send a similar signal back, it issues a warning. This allows it to detect spoofing calls originating from sources other than Phone by Google.

Google explains that this system utilizes Rich Communication Services (RCS) technology with end-to-end encryption, ensuring complete privacy.

This feature will be rolled out globally starting in June 2026, beginning with Pixel devices, and continuing on Phone by Google for devices running Android 12 and later. It is enabled by default, but you can disable it at any time through the Phone by Google app settings.

To date, Google has introduced several security measures to Android, including a feature that uses AI to verify messages and calls and detect scams.

Google stated, 'Phone and online fraud is a huge and ever-growing problem. A March 2026 Interpol investigation reported that impersonation scams caused more than $400 billion (approximately 63.9 trillion yen) in losses worldwide. For years, people have relied on the caller's phone number to judge who is who, but new methods are making that no longer sufficient. Our spoofing detection feature protects you, your family, and your friends by identifying whether the caller is who they claim to be.'
