What Google’s Fake Call Detection Is and Why It Matters
Google’s new fake call detection is an AI-powered scam call detection Android feature inside the Phone by Google app that analyzes incoming calls in real time to identify contact impersonation and warn users before they pick up. It focuses on a growing scam trend where attackers spoof caller IDs and use AI-generated voices to imitate family, friends, or trusted contacts, making requests that feel urgent and believable. The feature pops up a clear on-screen alert saying “This may not be [Name]” when it suspects the caller is pretending to be someone in your address book, giving you a chance to hang up before sharing personal information or money. As AI deepfake tools spread, this Google AI call blocking upgrade is designed to stop spam calls that slip past older filters and to strengthen Android security features without changing how people normally use their phones.

How Google Uses RCS and a Silent Signal to Spot Scams
Under the hood, fake call detection combines machine learning with a digital “handshake” built on Rich Communication Services (RCS). When someone in your contacts calls, their phone sends a silent confirmation signal through RCS to your device, verifying that the call truly comes from their number. If that confirmation is missing, the Phone by Google app treats the call as suspicious and warns you that the caller may not be who they claim. This approach targets modern scams where criminals spoof caller IDs and pair them with AI-generated deepfake audio to sound like your relatives or colleagues. According to Google, impersonation scams linked to realistic audio and video contribute to financial losses totaling $2.95 billion. By checking for this background signal, the system can block or flag AI-powered scam calls even when they appear to come from numbers you trust.

How to Enable Google’s New Scam Call Protection on Android
To benefit from this new scam call detection Android upgrade, you need a phone running Android 12 or later with the Phone by Google app. The feature is rolling out as part of Google’s June Android update and is switched on by default once installed, but it is worth confirming your settings. Open the Phone by Google app, tap the menu button in the top left, and look for the settings page where call protection options live. You and your trusted contacts also need RCS turned on in Google Messages so the silent confirmation signal can be sent and received. Within Google Messages, open settings and enable RCS chat if it is not already active. These small steps tie the new Google AI call blocking system into your everyday calling, adding another layer to Android security features without changing how you place or receive calls.
How This Upgrade Fits into Android’s Wider Security Story
Fake call detection is more than a standalone trick; it is a significant upgrade to Android security features that already include spam filtering, call screening, and caller ID. Earlier tools focused mostly on unknown numbers and known spam lists, but AI-powered fraud has blurred the line between safe and risky calls by copying voices and spoofing numbers from your contacts. This update extends protection to the calls users trust the most, reducing the success rate of social engineering scams that rely on panic, urgency, and familiarity. Combined with other June Android features—such as expanded personal safety tools and easier device sharing—Google is signaling that security and privacy are central to its ecosystem. For users, the message is clear: keep your device updated, enable RCS, and pay attention to on-screen warnings if you want to stop spam calls before they can turn into costly mistakes.
