Android’s new scam shields: Gemini in Google Messages, call-forwarding blocks and screen-share privacy

Google is adding a new layer of scam defenses across calls, texts and chat apps, according to an Android security post dated 14 October 2026. The headline change is an opt-in Enhanced protection mode in Google Messages, plus broader notification alerts and safeguards against call forwarding and screen-share snooping.

Enhanced protection in Google Messages

Google says Enhanced protection will roll out in the coming weeks. When enabled it unlocks:

• Scam Detection with Private AI Compute — cloud Gemini models review complex conversations with an unknown sender to spot slow-burn social engineering. Google says the analysis runs in Private AI Compute, with data encrypted and inaccessible to Google or others during that processing.
• Smarter link checks with Gemini Nano — on-device AI plus real-time web signals to judge unfamiliar links before you tap (availability limited to newer flagships such as Pixel 10+ and select Galaxy devices, per Google’s footnotes).
• Clearer checkpoints for links from numbers not in your contacts.

Existing on-device Scam Detection stays; Enhanced protection is meant to catch novel attacks that slip past simpler filters.

Beyond Messages

Google is also expanding scam detection in chat notifications — first seen on Pixel — to hundreds of millions more users later this year through partners including HONOR, Motorola, OPPO, OnePlus, realme, vivo, Xiaomi and others.

On the call side, Android will block apps from quietly turning on call forwarding and warn if someone tries to trick you into MMI forwarding codes (Pixel and select devices from early December, Google says). During live screen shares, sensitive fields in Chrome and Android WebView can be blanked automatically (rolling out this month on Android 15+).

Context Google cites

Google says AI-powered Scam Detection in Phone by Google and Google Messages already flags more than 5 million suspected scam calls and texts monthly. Separately it cites a Google-commissioned Leviathan Security Group assessment comparing built-in scam tools across platforms — treat that as company-funded research, not an independent regulator’s scorecard.

If you already ignore unknown texts, Enhanced protection is still worth watching once it appears in settings — especially for relatives who click every link.
