Google has announced a new security feature for Android devices aimed at protecting users from increasingly sophisticated phone scams powered by artificial intelligence. The feature, called Fake Call Detection, is designed to identify and flag suspicious calls in real time when scammers attempt to impersonate trusted contacts through spoofed phone numbers and AI-generated voices. The move comes as voice-cloning technology becomes more accessible, making it harder for users to distinguish genuine calls from fraudulent ones.
The new protection works through the Phone by Google application and relies on encrypted device verification technology. When a contact places a call, the caller’s device sends a secure confirmation signal to verify that the call is genuinely originating from that person’s device. If this verification process fails, Android can identify the call as potentially fraudulent and display a warning to the recipient. This allows users to receive an alert before falling victim to impersonation attempts.
According to Google, the feature is specifically designed to address a growing category of scams in which criminals use AI-generated voices to mimic family members, friends, employers, or other trusted individuals. In many cases, scammers combine voice-cloning technology with spoofed phone numbers to create highly convincing scenarios, often involving fake emergencies or urgent financial requests. The new system adds an additional layer of verification by confirming whether the call is actually coming from the contact’s device rather than relying solely on caller ID information.
The verification process operates in the background and uses end-to-end encrypted Rich Communication Services (RCS) technology. If a suspicious call is detected and the verification signal is missing, Android performs an additional check with the contact’s registered device. Should the system determine that the genuine device is not making the call, users receive an on-screen warning advising caution.
Fake Call Detection is being rolled out globally to Android 12 and newer devices during June 2026, beginning with Pixel smartphones. The feature is enabled by default and is expected to expand protection against one of the fastest-growing forms of digital fraud. Google has also indicated that the underlying technology has been built in a way that could allow broader adoption by additional applications and device manufacturers in the future.
The introduction of this capability reflects the increasing focus on combating AI-driven scams as cybercriminals continue to leverage advanced technologies to deceive users. By combining encrypted verification with real-time threat detection, Google aims to strengthen trust and security in everyday phone communications.
