Android Blocks 5M Scam Calls a Month, Adds AI Text Shields

What is Android's new scam protection and how does it work?

Android's new scam protection uses on-device and cloud AI to detect fraudulent calls and texts before users interact with them. Google says the system already flags 5 million suspected scam calls and messages each month across its Phone and Google Messages apps, and the new features expand that coverage.

Google announced the updates in a blog post on Wednesday, describing them as built-in defenses that block scams before they happen. The protections span Google Messages, screen sharing and call forwarding, with some features rolling out immediately and others arriving later.

The company commissioned a YouGov survey of 4,500 adults and found that 40% are very or extremely concerned about mobile fraud. Google is positioning the new tools as a direct response to that anxiety.

How does Google Messages enhanced protection detect scams?

An optional setting in Google Messages enables an enhanced protection mode that uses AI to evaluate more message content, screen malicious links and flag unfamiliar numbers. Google says the AI processing happens privately with encryption on its servers, and the feature rolls out over the next few weeks.

According to Google, the enhanced mode can understand a scammer's intent more quickly when a user is in a conversation with an unknown sender. It will also check for malicious links and unfamiliar numbers that often signal fraud.

The setting is not available immediately. Google says it will reach users over the coming weeks, and it remains optional rather than default-on.

Which phones will get scam detection in chat notifications?

Later this year, Google will bring scam detection to chat notifications on phones from Motorola, OnePlus and Xiaomi, as well as on its own Pixel devices. The expansion means the protection is not limited to Google's hardware.

Google's Pixel phones will receive the feature alongside third-party Android devices. This broad rollout could affect former Samsung Messages users, since that service shut down in July and users were urged to switch to Google Messages.

The timing is notable: Samsung Messages users who migrated to Google Messages will be among the first to encounter the new protections as they arrive.

How does screen sharing and call forwarding protection stop scammers?

During screen sharing, Android will automatically hide login fields so passwords and sensitive information are not visible. Separately, proactive call-forwarding protection blocks apps from forwarding calls without notifying the user, which stops scammers from intercepting passcodes and hijacking accounts.

Screen sharing is a common vector for fraud because scammers can watch a victim type credentials in real time. By hiding password fields automatically, Android removes that opportunity without requiring the user to take action.

Call forwarding is another known tactic: fraudsters set up forwarding to intercept one-time passcodes sent via SMS or voice. Google's new protection requires notification before any app can forward calls, giving users a chance to stop it.

What does this mean for Android users right now?

Android users do not need to do anything to benefit from most of the new protections, but the Google Messages enhanced protection mode is optional and will appear over the next few weeks. Users should watch for the setting and enable it if they want AI screening of unknown senders.

The call-forwarding and screen-sharing protections are system-level and should apply automatically once the update reaches a device. The Google Messages enhanced mode is the main feature that requires user opt-in.

Google's 5 million monthly scam flags suggest the problem is widespread. The new tools aim to reduce that number by catching fraud earlier in the conversation.

1. Check Google Messages settings in the coming weeks for the enhanced protection toggle.
2. Keep an eye on call-forwarding settings if you notice unexpected forwarding.
3. Update Android system components when prompted to receive screen-sharing protections.
4. Report suspected scam texts and calls to help improve detection.

Bottom line

Google's new Android scam defenses bring AI screening to Google Messages, automatic password hiding during screen sharing, and call-forwarding safeguards that block a common account-hijack tactic. The features roll out over the coming weeks and months, with broader device support later this year. Android users should enable the Google Messages enhanced protection mode when it appears and stay alert to unexpected call-forwarding changes.
