Google rolled out AI-powered defenses on Android to detect scam messages and call-forwarding abuse, targeting increasingly sophisticated attacks such as spoofed numbers, fake bank alerts, and AI voice cloning. Existing Phone and Messages systems already flag more than 5 million suspected scam calls and texts monthly; the new protections add cloud-based Gemini analysis running inside Google's encrypted Private AI Compute to scrutinize conversations with unknown senders, while on-device Gemini Nano scans unfamiliar links using real-time web signals and shows clearer warnings before opening links from unsaved numbers. Cloud-based protections are disabled by default and require users to opt in.
Other enhancements include wider rollout of on-device scam detection in chat notifications beyond Pixel phones, expansion of sensitive-information masking to Chrome and Android WebView during live screen sharing, and blocking apps from silently enabling call forwarding with warnings before manually entered MMI forwarding codes take effect. The verified bank calls system has been expanded to more financial institutions and will automatically end calls that fail verification; Google reports it has blocked over 3 million fraudulent bank-related calls since June for Banco do Brasil and Itaú Unibanco. Users are advised to update Android and apps and independently verify callers or senders before sharing account or sensitive information.
