How to Enable Built-In Fraud Detection on Xiaomi Security App
Xiaomi's Security app (pre-installed on all MIUI/HyperOS phones) includes several anti-fraud tools that most users never discover. Here's how to activate them.
Open the Security App
- Find Security app in the app drawer (shield icon).
- Or: Settings → Privacy → Security app on some HyperOS builds.
Feature 1 – Phone Shield (Call Fraud Detection)
- Open Security → Phone & SMS filter.
- Enable Caller ID and spam protection.
- Unknown callers are checked against Xiaomi's crowdsourced scam database.
- Suspicious calls are flagged with a warning banner: "Suspected fraud" or "Telemarketing."
Feature 2 – SMS Filter (Scam Text Detection)
- Security → Phone & SMS filter → SMS filter → enable.
- Xiaomi scans incoming SMS for:
- Phishing links.
- Fraudulent OTP scams.
- Fake bank/delivery notifications. - Suspected spam SMS is moved to a Spam folder, not your main inbox.
Feature 3 – App Scanning (Virus & Malware)
- Security → Virus scan.
- Tap Scan — Xiaomi Security checks all installed apps against its threat database.
- Suspicious apps are flagged and quarantined.
- Enable Auto scan: Security → Settings → Auto scan → on.
Feature 4 – Payment Shield
- Security → Payment protection → enable.
- When a banking or payment app is opened, Xiaomi scans for:
- Screen overlay attacks (other apps drawing over your banking screen).
- Suspicious background apps running during payment.
- Accessibility service abuse. - Alerts you if a potential threat is detected before you enter credentials.
Feature 5 – Data Breach Monitoring
- Security → Privacy → Check for leaks.
- Enter your email address.
- Xiaomi checks against known data breach databases.
- Alerts you if your email appears in leaked databases — prompts password change.
Key Settings to Enable
| Feature | Where | Recommended |
|---|---|---|
| Caller ID & spam detection | Security → Phone filter | ✅ On |
| SMS spam filter | Security → SMS filter | ✅ On |
| Auto virus scan | Security → Settings | ✅ On |
| Payment protection | Security → Payment protection | ✅ On |
| Safe browsing (Mi Browser) | Mi Browser → Settings → Safe browsing | ✅ On |
Pro Tips
- Keep the Security app updated via Google Play or MIUI App Store — scam databases update frequently.
- Even with all protections on, never share OTPs over the phone — legitimate banks and services never ask for them.
- If you receive a suspicious call, check the number at shouldianswer.com or similar community scam reporting sites.
