US-based tech giant Google has introduced a new security feature for Android users to protect them from a rapidly growing form of fraud, i.e., AI-powered impersonation scams . The new feature is named 'Fake Call Detection' , and it is claimed to identify and flag suspected spoofed calls where scammers use artificial intelligence to clone the voice of someone the victim knows.
The company claims that the newly launched tool is first of its kind in the smartphone industry and is aimed at fighting against the rapidly growing sophisticated deepfake attacks.
The feature is launched as fraudsters are rapidly using AI generated voice and caller ID spoofing to trick people into believing they are speaking to a family member, friend, or a known person. In a typicalscam, the fraudster mimics a person's phone number and voice to create a fake emergency or financial request.
According to the tech giant, the new fake call detection feature works automatically when both caller and recipient use the Phone by Google app. When a legitimate call is placed, the caller's device sends a secure verification signal to the recipient's phone through end-to-end encrypted Rich Communication Services (RCS) technology.
How the Feature Works
The company explains the system as a digital handshake between devices. If a caller claims to be someone from your contacts but the verification signal is missing, Android checks with the actual contact device to confirm whether they are calling or not.
If the contact device confirms no call is being placed, the recipient receives an on-screen warning that the caller may be impersonating someone they know. The alertsadvise users toend the call urgently.
Thewhole processruns silently in the background. You will not see anything happening unless there is a problem. And if a scammer is on the line pretending to be your sibling or your boss, your phone will catch the mismatch and warn you before you say or do anything you regret. The feature is turned on by default, so most users will not have to do anything to activate it.
For this to work, both the caller and the recipient need to be using the Phone by Google app, along with Google Messages and Google Contacts. It currently works on Android 12 andabove andis rolling out globally starting with Pixel devices this month.
Why This Matters Right Now
The timing of this launch is not a coincidence. Scammers have gottenvery goodatsounding likehumans. According to INTERPOL's March 2026 Global Financial Fraud Threat Assessment, impersonation fraud is one of the leading causes of more than$400 billionin global losses. In 2024 alone, Americans lostnearly$3 billionto impersonationscams, and the numbers have been climbing every year since.
The reason thesescamswork is simple. People used to rely on caller ID to know who was calling. But scammers figured out how to fake that too. Now they spoof a number from your contact list and layer an AI-generated voice on top, so the person calling you sounds exactly like your mother, or your manager, or yourbank'scustomer care executive.
Most people cannot tell the difference anymore. Researchers and security experts have consistently found that human ears struggle to detect high-quality AI audio.SoGoogle decided the phone itself needed to do the checking.
What Comes Next
Google has built this feature on top of RCS, which means other app developers and phone manufacturers can also adopt it over time. That is an important detail. If the technology stays limited to Pixel phones or only Google's own apps, its reach will stay narrow. But if other Android manufacturers pick it up, it could become a standard layer of protection across the entire ecosystem.
For now, anyone on Android 12 or above using the Phone by Google app will start seeing the feature roll out over the coming weeks. There is no opt-inrequiredand no complicated setup.
