In response to this escalating issue, Google has introduced a new feature for Android devices aimed at detecting and alerting users about fraudulent calls. The fake call detection feature is being rolled out through the Phone by Google app and is intended to recognize instances where a caller may be pretending to be someone familiar to the recipient.
In a blog announcement, the tech giant stated, “To assist in protecting you from the rising threat of impersonation scams, Android is introducing fake call detection, an industry-first protection that can identify and flag suspected spoofed calls when both you and your contact are using Phone by Google.”
How AI-driven impersonation scams function
Imagine receiving a call that seems to be from your mother, father, or a close friend. The caller ID displays a known name, and the voice mimics that of the person you recognize. However, the call is actually from a fraudster who has leveraged AI voice-cloning technology to replicate that individual.
These scams, often labeled as deepfake attacks, are gaining prevalence as artificial intelligence tools become more accessible. Crooks utilize these technologies to imitate real voices, tricking individuals into divulging sensitive details or transferring funds.
Impersonation fraud is on the rise
Global authorities have warned that impersonation scams are evolving into one of the most damaging forms of fraud. According to Interpol’s March 2026 Global Financial Fraud Threat Assessment, these scams account for over $400 billion in global losses.

Historically, individuals relied on caller ID to verify incoming calls. However, scammers now manipulate phone numbers using internet-based software, creating the illusion that calls originate from trusted contacts. When paired with AI-generated voices, these strategies formulate a powerful tool for deception.
How Android’s fake call detection operates
The new Android feature employs a verification method that operates discreetly in the background whenever two users are connected via Phone by Google.
When a legitimate call occurs, the caller’s device sends a silent confirmation signal in real time, affirming that the call is indeed coming from that contact’s phone. This process utilizes end-to-end encrypted Rich Communication Services (RCS) technology and maintains complete privacy.
If a scammer tries to spoof a contact’s number, the initial confirmation signal will be absent. Consequently, the recipient’s device automatically checks with the real contact’s phone. If the actual device verifies that no call is being made, Android promptly shows a warning advising the user to hang up.
This feature is enabled by default, though users can turn it off via the settings in the Phone by Google app.
Global rollout commences this month
Google has revealed that fake call detection will start rolling out globally to Android devices running Android 12. Initially, the feature will be available on Pixel smartphones. Phone by Google is already the default calling application on various Android devices. Users of alternative phone apps can download Phone by Google from the Play Store and set it as their default phone app to use this new feature.
