Android Deploys Fake Call Detection as AI Voice Scams Target U.S. Officials

Google launched fake call detection in Phone by Google on June 2, a feature designed to identify and flag suspected AI-generated impersonation calls in real time. The rollout begins with Pixel phones running Android 12 and later, with a global expansion underway.

The system operates on a real-time digital handshake built on Rich Communication Services (RCS), an encrypted messaging standard that has replaced SMS on many Android devices. When a call arrives from a saved contact, Phone by Google silently signals the contact’s device to confirm the call is legitimate. If that signal is missing, the app sends an authenticated RCS ping to the contact’s actual phone. If the contact’s device reports it is not currently placing a call, the user receives an on-screen warning to hang up immediately. Google stated the handshake is end-to-end encrypted, making the verification process private.

The Federal Trade Commission (FTC) tracked nearly $3 billion in impersonation scam losses in 2024. The FBI’s 2025 Internet Crime Report documented nearly $21 billion in total cyber-enabled fraud, with AI-assisted schemes among the costliest categories.

The FBI’s Internet Crime Complaint Center (IC3) issued a public service announcement in May 2025 warning that since April 2025, malicious actors had been using AI-generated voice messages to impersonate senior U.S. government officials, targeting current and former federal and state personnel in efforts to gain access to their private accounts.

Government impersonation complaints nearly doubled between 2024 and 2025, with the IC3 recording $797 million in associated losses last year.

Google built the system on open RCS standards to allow other developers to adopt the same verification architecture. The feature requires both parties to use Phone by Google, Contacts, and Google Messages, and will not function on devices running third-party phone applications.
