Android Targets Impersonation Scams With Fake Call Detection Feature

Android is introducing a new feature designed to warn users when incoming calls may be spoofing trusted contacts, as phone scams increasingly rely on impersonation tactics and manipulated caller IDs. The feature, called Fake Call Detection, will begin rolling out globally this month.

The feature works by verifying whether an incoming call originates from the contact’s device. If Android detects that a call claiming to come from a saved contact cannot be verified, users will receive a warning during the call, and caller information may be replaced with a generic “Unknown” label.

Fake Call Detection relies on encrypted signals exchanged between devices using Rich Communication Services (RCS) and currently works when both the caller and recipient use Phone by Google on Android devices running Android 12 or later. Initial rollout will begin with Pixel devices before expanding more broadly.

The feature is being developed because impersonation scams continue to grow. According to Google, scammers increasingly use caller ID spoofing techniques and voice cloning tools to imitate family members, colleagues, banks, and other trusted contacts. Fraud involving impersonation remains among the most commonly reported scam categories globally.

The launch builds on Google’s earlier efforts around verified banking calls and scam detection tools already available on Android. Unlike traditional spam filtering, Fake Call Detection focuses specifically on situations in which attackers attempt to impersonate someone already known to the recipient.

The update is part of Android’s broader June feature rollout, which also includes expanded safety tools and new cross-device capabilities, though the anti-spoofing feature is likely to receive the most attention as fraud prevention becomes a larger focus for mobile platforms.
