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”. ## Related articles - “How HiFi blocks spam and scam calls” - “Report spam and block a caller” - “Keep part of a call private with Incognito” - “Read a call summary and transcript”
