Google is rolling out a significant update aimed at protecting Android users from the growing threat of AI-powered impersonation scams. The new scam call detection feature, announced as part of a wider Android update, leverages a multi-app verification system to flag spoofed calls that appear to come from known contacts. This comes as the Federal Trade Commission reports nearly $3 billion in losses from such scams in 2024, with advances in AI voice cloning making it increasingly difficult for victims to distinguish a fake caller from a loved one or colleague.
How the Verification System Works
The core mechanism of Google's anti-fraud system relies on a coordinated effort between three of the company's most popular communication apps: Phone by Google, Google Contacts, and Google Messages. When a call arrives that claims to be from a contact in your address book, the Google Phone app checks for a confirmation signal that authentic callers send through their own dialer. Spoofed calls, which use online relays to mask the real number, lack this signal. In such cases, the Phone app triggers Google Messages to send an authenticated RCS (Rich Communication Services) ping to the supposed caller's phone number. If the recipient's device reports that it is not currently placing a call, the system generates a pop-up warning the user that the caller may be an impostor.
This process requires both the potential victim and the person being impersonated to have installed all three Google apps. As Google notes, the scammer is unlikely to have these apps configured, and the RCS authentication provides a second layer of validation. The feature will be available on all devices running Android 12 or higher, though adoption depends on phone manufacturers. Pixel and Motorola devices come preloaded with Google's apps, and Samsung has switched to Google Messages by default. However, users of Samsung's own Phone and Contacts apps or OnePlus's dialer will need to switch to Google's apps to benefit from the protection.
Expanding Beyond Financial Calls
This new system builds on a feature Google debuted last month that verified calls from financial institutions. The expansion to all contacts addresses the most common deepfake scam scenario: scammers spoof a contact's number and use an AI-generated voice clone of that person to fabricate an urgent need for cash. The sophistication of voice cloning tools, which can replicate tone, cadence, and even emotional inflections, has made it nearly impossible for victims to identify fakes based on conversation alone. By adding a technical verification step, Google aims to create a barrier that scams cannot easily bypass.
The success of this approach hinges on widespread adoption of the three Google apps across the Android ecosystem. While Google claims Phone by Google is the most widely used dialer, Samsung's own phone app ships on tens of millions of devices. Google is betting that the security benefit will encourage users to switch, especially as regulators in some countries have advised Android users to avoid using their phones for financial transactions due to scam risks.
Circle to Search Gets a Fashion Upgrade
Alongside the scam detection news, Google is also expanding its AI-powered Circle to Search feature. The 'Find the Look' capability, previously available only on Pixel 10 and Galaxy S26 models, is now rolling out to all devices running Android 14 or higher. This feature allows users to circle any image on their screen and instantly identify all visible items of clothing—from jackets and shirts to shoes and accessories. The AI parses textures, patterns, and styles to provide links to purchase or similar items.
Google also announced that Google Photos will soon include an AI-assisted fashion engine. The app will automatically catalog clothing worn in your photos, creating a virtual wardrobe that you can browse, organize, and even use to generate AI images of yourself wearing specific outfits. While the feature is designed for convenience and style experimentation, Google cautions that AI-generated images may not perfectly reflect real-world fit and appearance.
AirDrop Support Spreads to More Android Devices
In a move that continues to bridge the gap between Android and iOS ecosystems, Google is expanding AirDrop support to a wider range of Android phones. Previously limited to the latest Pixel and Samsung flagship phones, the feature now includes devices from OnePlus, Xiaomi, Vivo, and HONOR. The list of newly supported models includes the Samsung Galaxy S25 series, Galaxy Z Fold7, Galaxy Z Flip7, Galaxy S24 series, Z Fold6 and Z Flip6; the OnePlus 15; Xiaomi 17T Pro; Vivo X300 and X300 Pro; and HONOR Magic V6. Users can now send files directly to nearby iPhones and other Android phones using AirDrop, though the iPhone must be set to accept sharing from 'anyone for 10 minutes' for the transfer to work. Contact-based sharing from Android remains unsupported, but the broader availability is a welcome improvement for cross-platform file exchange.
The combination of enhanced scam protection, AI-driven fashion tools, and expanded interoperability reflects Google's strategy to make Android more secure, intelligent, and connected. As AI voice scams continue to evolve, the new call authentication system could become a critical line of defense for millions of users. However, its success will depend on willingness to adopt Google's app ecosystem and the cooperation of phone manufacturers in preloading or promoting these apps.
