You can identify, find and remove trackers that have been placed near you or in your belongings without your knowledge or consent with the help of Unknown tracker alerts.
What are trackers?
A tracker, also called a tag, is a small Bluetooth device that you can attach to items like keys or a backpack to help you find them when they get lost.
In some cases, these devices may be misused to track people without their consent.
What is an Unknown tracker alert?
An Unknown tracker alert is sent when someone else’s tracker device is separated from them and your Android phone detects that the tracker is travelling with you and out of Bluetooth range from the owner. The notification alerts you to the tracker and tells you how to find it and what to do next.
Tips:
- You may get these notifications if you borrow an item or if you are travelling with someone who has a tracker with them.
- You can’t stop a tracker’s ability to share its location by turning on aeroplane mode or turning off Bluetooth or Location Services on your phone. Learn how to turn off a tracker.
Unknown tracker alerts currently work with Find My Device network-compatible tags and Apple AirTags.
What to do if you get an Unknown tracker alert
Important: If you turn off Bluetooth or Location Services, or turn on aeroplane mode, your phone won’t prevent the owner of the tracker or device from finding the location of the tracker. To disable the tracker, follow the instructions provided by the manufacturer.
- On your device, tap the tracker notification to open a map.
- Find where the tracker has been detected travelling with you.
- Tap Play sound, which causes the tracker to make a sound.

You’ve got an Unknown tracker alert
If you get a notification on your Android phone or tablet, a tracker that’s not yours could be moving with you.
It’s possible that the tracker is attached to or in something that you’re borrowing, such as keys or a backpack.
To learn more about the tracker, such as the type of device and name of the manufacturer, tap the notification.
When you tap the notification, it’ll show you a map where the tracker was detected moving with you.
- You won't find where the owner of the tracker checked its location.
Play sound to find an unknown tracker
If you get an alert, to help you locate the tracker, you can have it play a sound by tapping Play sound.
If you still can't find the device, make the tracker play a sound again by tapping Play sound.
Tip: You won't notify the owner of the tracker if you've played the sound.
If you can’t play or hear a sound
If you’re unable to play a sound or can’t hear the sound, try to move around and tap Play sound. It’s possible that the tracker is no longer in range or the device ID has changed.
If you can't play a sound but believe that the tracker is near you, look through your belongings. Search yourself and your surroundings for anywhere the device may be hidden. This could be in places where you don’t commonly look, like in a pocket, your bag or your car.
If you can't find the device and feel that your safety is at risk, go to a safe public location and contact the police or a trusted contact.
You can take screenshots of the Unknown tracker alert and the map of the tracker locations for later reference.

If you can’t find the device, it may still be near you or on your belongings.
- If it’s safe to do so, retrace your steps and check belongings that you had on the route shown on the alert, like in your car or backpack.
- Run a manual scan to find trackers nearby.
- If the tracker is still detected with you the next day, you may receive another alert.

- On your device, tap Settings.
- Tap Safety and emergency Unknown tracker alerts Scan now.
- Your device takes about 10 seconds to complete a manual scan.
Which trackers show up in a manual scan
You can detect trackers that are currently near you and separated from their owner’s device with a manual scan. It’s possible that the trackers found in a manual scan are simply misplaced or temporarily separated from their owner’s device.
If you’ve turned on Unknown tracker alerts, you’ll get a notification automatically if the system determines that an unknown tracker is moving with you.
Didn’t get an alert for a tracker in a manual scan
Trackers that appear in a manual scan are currently near you, but may not have been travelling with you.
If you have alerts turned on, you’ll be notified automatically if the system determines that an unknown tracker is moving with you.
How your phone received the update
To keep your Android phone safe, it regularly gets updates in the background. During an update, Play Services added the Unknown tracker alert system, and you will automatically get notifications about an unknown tracker.
If you would like to opt out, you can do so at any time.
Turn off Unknown tracker alerts
Important: If you turn off Unknown tracker alerts, previous alerts will be cleared and any information about other unknown trackers will be deleted. This data can’t be recovered.
If your Android device is Android 12 (S) and up:
- On your device, tap Settings.
- Tap Safety and emergency Unknown tracker alerts.
- Turn Allow alerts off.
If your Android device is Android 11 (R) and lower:

Your data and privacy
To determine how an unknown tracker has travelled with you, Unknown tracker alerts use your location information and timestamps of when your device detected the tracker, and a device ID for the tracker. When you receive an Unknown tracker alert, you’ll also find the places that the tracker was detected with you on a map.
This information is processed and temporarily stored in an encrypted format, never leaving your device, to determine if there’s a tracker following you and displaying it to you on a map. It’s not shared with Google or other users.
Android location settings privacy
To get automated alerts for unknown trackers travelling with you, you must have your location turned on.
If you turn off your location, to find trackers that are near you at the moment, you can still use the manual scanning feature.
- On Android 11 and up: Manual scanning doesn’t require the phone's location setting to be on. Check and update your Android version.
- On Android 10 and lower: Manual scanning uses your phone’s location setting and Bluetooth. There are several ways that you can control which apps and services can access your location.
Troubleshoot problems with unknown trackers
Why can’t I ring a tracker after I get an alert?
You may not be able to ring the tracker if:
- The tracker owner is nearby
- The tracker was very recently separated from its owner
- The tracker is out of your Android phone’s Bluetooth range or no longer with you
- The tracker device ID has changed
What does it mean if the tracker’s device ID has changed?
Each Bluetooth tracker has a random ID associated with it that changes periodically. If the tracker isn’t near its owner, it may change less frequently, such as once per day.
When the tracker changes its random ID, it's no longer identified as the same tracker, and your Android device will display it as a new tracker in future scans or alerts.
Why didn’t I get the alert sooner?
Unknown tracker alerts consider multiple factors when sending an alert. To improve alert accuracy, you need to physically move with the tracker over time before receiving an alert.
Why didn’t I receive more than one alert?
The system is currently built so that you will receive only one alert, per tracker, each day. If you’re still concerned that a tracker is with you, run a manual scan to find nearby trackers.
Why didn’t my manual scan detect nearby trackers?
To show trackers in the manual scan feature, they must be separated from their owners physically. Running multiple manual scans may improve the accuracy of the nearby trackers detected.
