Google strengthens scam protection on Android: an optional mode in Messages and more call safeguards

If you sell by message, get paid by bank transfer or serve customers from your phone, fraud attempts are part of the day. Google announced a package of AI defenses for Android on October 14.

What it announced

• Enhanced protection in Google Messages: this is an opt-in setting. With it, scam detection can draw on Gemini models in the cloud, through what Google calls Private AI Compute, to better understand the context of a conversation and spot a possible scammer's intent sooner when an unknown sender writes to you. Google said it will roll out in the coming weeks. The Private AI Compute analysis is available on Pixel 6 and newer, the Galaxy S24 series and newer, Galaxy Z Flip and Z Fold6 and newer, and other Android AICore devices.
• Safer links: another layer uses Gemini Nano, which runs on the phone itself, to check in real time whether an unfamiliar link is trustworthy before you tap it. Google explained that attackers register brand-new sites all the time and existing protections haven't cataloged them yet. This check is available on Pixel 10 and later, the Galaxy S26 series, Galaxy Z Flip and Z Fold8, and other select devices.
• Warnings before opening links: Google redesigned the warnings that add context before you open links from numbers outside your contacts. That checkpoint was previously limited to devices in select countries or running Android Advanced Protection. These warnings are available on devices running Android 6 or later.
• More private screen sharing: Android already automatically hid sensitive information, such as password fields and payment screens, while you share your screen in native apps. It now extends that to Chrome and Android WebView. It rolls out during October to phones running Android 15 or later.
• Scam alerts in chat notifications: Google is partnering with device makers to expand Scam Detection in notifications, a feature that launched on Pixel and flags suspicious messages before you open a chat app. Availability varies by manufacturer, and Google said it will reach hundreds of millions of additional users later in 2026.
• Call safeguards: Android now prevents apps from silently switching on call forwarding in the background, and it warns you before a manually entered forwarding code on the dial pad can take effect. Google explained that scammers use such redirection to intercept calls and steal one-time passcodes. This protection will be available starting in early December 2026 on Pixel and other select devices.
• Verified bank calls: working with banks such as Banco do Brasil and Itaú Unibanco, Android uses official banking apps to verify in real time whether an incoming call was genuinely initiated by the bank. If a caller claiming to be from the bank fails the check, Android ends the call and alerts you immediately.

The number

Google says its scam detection tools now flag more than 5 million suspected scam calls and texts every month.

What to do

When the option reaches your phone, check in Google Messages settings whether enhanced protection appears and decide whether to turn it on. Keep in mind that several features are only on certain models, so what you see will depend on your phone. Meanwhile, the usual rule still applies: don't tap links from numbers you don't know and don't share your screen with strangers. The source says some features may not be available in all countries but doesn't detail which ones, so check your phone over the coming weeks.
