EXCERPT: Got an alert about an unknown tracker? Learn how to find, identify, and disable it on iPhone or Android before it compromises your privacy.
If your phone suddenly warns you about an unknown tracker, it means a device is secretly reporting your location. This could be a physical tracker like an AirTag attached to your belongings, an app quietly monitoring you, or a paired device you don't recognize. Here's how to find it and shut it down.
What Triggers This Alert
Modern phones have built-in systems that detect unknown tracking devices moving with you. Apple introduced AirTag alerts in iOS 14.5, and Android added similar tracker detection in Android 12 and later. These systems work by detecting Bluetooth signals from trackers you don't own.
The alert usually means one of two things: someone physically placed a tracker on you or your belongings, or an app on your phone is transmitting your location without your knowledge.
Quick Checks to Narrow Down the Source
Before digging into settings, answer these questions:
- Did you recently lend a bag, jacket, or car to someone?
- Have you borrowed or purchased a secondhand item recently?
- Do you share a household with someone who uses tracking devices?
- Did you install any new apps recently, especially from outside your official app store?
How to Find and Disable an Unknown Tracker on iPhone
If you received an "AirTag Found Moving With You" alert, follow these steps:
- Open the alert notification. Tap it directly from your lock screen or notification center. It will begin playing a sound to help you locate the tracker.
- Follow the directional arrow. On iPhone 11 and later, tap "Navigate" in the alert to use precision finding. Follow the on-screen arrows toward the tracker.
- Check your belongings. Inspect bags, coats, keys, purses, and under car seats. The tracker is likely attached to something you own.
- Manually scan for Bluetooth devices. Go to Settings > Privacy & Security > Location Services and scroll to the bottom. Tap System Services and check Finding for any unrecognized devices.
- Use the Find My app. Open Find My > Devices. If an AirTag or "Unknown Location" tracker appears that you didn't register, it's not yours.
Once you find the tracker, keep it pressed against your phone. If it's an AirTag, you'll get a prompt to disable it. You can also tap the tracker's button to put it in lost mode temporarily, though this doesn't permanently disable it.
How to Find and Disable an Unknown Tracker on Android
- Open the notification. Android shows an alert when an unknown tracker is detected. Tap it and select Find to begin searching.
- Follow the on-screen guidance. Android will give you directional cues and, on compatible devices, haptic feedback as you move closer.
- Check nearby Bluetooth devices. Go to Settings > Location > Scanning and review Bluetooth scan results for anything unfamiliar.
- Review installed apps. Go to Settings > Apps and look for apps you don't remember installing — especially those requesting location permissions.
Android also supports a dedicated tracker detection feature. Go to Settings > Security > Unknown Tracker Alerts to toggle detection on or off and review any alerts you've received.
Suspicious Apps Monitoring Your Location
If the tracker alert isn't about a physical device, an app may be the culprit.
- Check your location settings. On iPhone: Settings > Privacy & Security > Location Services. On Android: Settings > Location > App location permissions.
- Review which apps have "Always" access to your location.
- Revoke access from any app you don't trust or don't actively use.
- If you suspect spyware, look for apps with generic names like "System Service," "Location Helper," or similar — these are common disguises for stalkerware.
If you find a suspicious app, uninstall it immediately. Restart your phone and recheck your location permissions.
If You Can't Find the Tracker
Try these troubleshooting steps:
- Restart your phone to refresh Bluetooth and location services.
- Move away from buildings and crowds — the tracker signal can be blocked or confusingly bounced.
- Have someone else hold their phone nearby while you walk around the area to isolate the signal.
- Check your car, especially the wheel wells, under seats, or inside the trunk.
- If the alert persists for days and you can't locate the device, contact local law enforcement. Tracking someone without consent is illegal in most jurisdictions.
Permanent Protection
- iPhone: Keep AirTag detection enabled. It's on by default and will alert you to any unknown AirTag or compatible tracker.
- Android: Enable "Unknown Tracker Alerts" in your security settings.
- Both platforms: Avoid sideloading apps and only install from official app stores.
- Periodically review your location permissions and Bluetooth-paired devices.
When to Seek Help
If you believe someone is tracking you intentionally and the tracker keeps returning despite your efforts, this may be a safety concern. Contact local authorities and consider requesting a forensic device scan from a professional technician to detect hidden spyware.
