WhatsApp Beta Brings On-Device Scam Alerts to Android

If you’ve ever opened WhatsApp and felt a chill at an unfamiliar message asking for money or personal details, relief may be arriving — and quietly. WhatsApp has started testing a Scam Alert feature with some Android beta users, and it runs entirely on your phone.

The discovery came from WABetaInfo, which spotted the functionality in WhatsApp for Android beta build 2.26.34.1. Meta has already described the feature publicly, though the company hasn’t given a firm date for a full release. Still, seeing it in the wild suggests a broader rollout is within reach.

Scam Alert watches incoming messages from unknown senders and flags those that look suspicious. The sender never knows. When the app raises a warning, you get choices: mark the sender as trusted, block and report them, or — if you want to help improve detection — share the last five messages of that conversation with WhatsApp.

The feature is optional. It won’t turn on by itself. You enable it manually through WhatsApp’s Settings > Account menu, so users keep control over whether they want this extra layer of protection.

No message content leaves the device for classification or is auto-reported to WhatsApp, Meta, or anyone else. In plain terms: an on-device machine learning model scans for scam signals locally, and the alert is generated without sacrificing end-to-end encryption.

That design matters. It’s an attempt to thread a needle many apps struggle with — protecting users from fraud while preserving the privacy guarantees people expect from encrypted messaging. Think of it as a silent watchdog living in your phone; it barks only when it smells trouble, and it doesn’t tell others what it sniffed.

For now, the rollout remains limited to beta testers, but the mechanics are clear: machine learning runs locally, users opt in, and they decide whether to escalate or dismiss a warning. If you’re enrolled in WhatsApp’s Android beta, check for the 2.26.34.1 update and the new option in Account settings. If you’re not, keep an eye on the app — this privacy-first scam guard could save more than a few people from digital harm.
