How does HiFi warn me about scams during a call?
HiFi watches for signs of a possible scam while you’re on a call and warns you right away. It looks for two things:
Scam tactics. The other person uses language or pressure tactics that scammers often use.
An AI-generated voice. The voice on the call may be AI-generated or created by a machine, rather than a real person speaking.
The warning comes while you’re still on the call, so you have time to decide what to do. You don’t need to turn anything on.
How will I know HiFi has a warning for me?
HiFi shows an alert on the call screen and vibrates your phone, so you notice even if you’re not looking at the screen.
An on-screen alert explains what HiFi noticed.
Your phone vibrates. A scam warning vibrates longer than an AI-voice warning.
On iPhone: three pulses for a scam warning, one pulse for an AI-voice warning.
On Android: a 3-second vibration for a scam warning, a 1-second vibration for an AI-voice warning.
You can read the alert without leaving the call.
What does a scam warning say?
A scam warning appears when HiFi notices language or tactics often used by scammers. The alert is titled Potential scam call and says: “We have detected language or tactics often used by scammers. Use caution when sharing sensitive information or following their instructions. If you’re unsure, end your call.”
On iPhone, a banner first appears at the top of the call screen: Fraud Detected, “Caller matches known scam patterns. Proceed with caution”. Tap it to open Fraud details.
The alert has two buttons:
Dismiss: Closes the alert and keeps the call going.
End call: Ends the call.
What does an AI-voice warning say?
An AI-voice warning appears when the voice on the call may be AI-generated or not a real person. The alert is labeled AI or non-human voice and says: “This may be an AI generated or non-human voice. Use caution.”
On iPhone, the banner reads “This is an AI generated or digitally created voice. Use caution.”
Some scammers use AI voices to sound like a family member, a bank, or a company you trust. If a caller asks for money, codes, or personal details, end the call. Then call the person or company back on a number you know is theirs.
What should I do if I get a warning?
A warning means HiFi noticed signs of a possible scam. It doesn’t confirm that the caller is a scammer. Use it as extra information when you decide whether to keep talking.
Don’t share passwords, one-time codes, bank details, or your Social Security number.
Don’t send money or gift cards because a caller asks you to.
If you’re unsure, tap End call. Then call the person or company back using a number you already trust.
If you know the caller and the warning doesn’t fit, tap Dismiss and keep talking.
After the call, you can report the number and block it. See “Report spam and block a caller”.
Can I see warnings after the call?
Yes. Call Details shows whether HiFi noticed signs of scam tactics or an AI-generated voice during the call. Open the call from Call Activity on Home to see the signal next to the summary and transcript. If you think the call was a scam, you can report and block the number from the same screen.
Do scam warnings work when Incognito is on?
No. While Incognito is on, HiFi pauses scam and AI-voice warnings along with its AI listening. Warnings start again when you turn Incognito off. If you’re talking with someone you don’t know, consider leaving Incognito off so HiFi can keep watching for scam tactics. See “Keep part of a call private with Incognito”.
