Deepfake audio scams in particular have been getting harder to spot with just your ears.
And the way it works is the AI listens and watches for patterns that don't add up, numbers that look wrong, voices that sound slightly off, messages coming through RCS that match known fraud signatures. It flags them before you even pick up or reply. The detection runs on the Phone by Google app, so it's not a separate download or a setting buried somewhere. It's just there, running quietly in the background every time a call or message comes in through RCS.
Google rolling this out in June 2026 isn't a coincidence either, because scam and deepfake fraud cases have been climbing steadily, and pressure on big tech companies to do something about it has been building for a while. The feature is part of a broader drop that Google said includes other AI tools, but the scam and deepfake detector is the one getting the most attention. RCS flagging in particular is new ground, since most scam filters have focused on regular calls until now.
