I'm not sure, but GIYF! Here's what my search turned up:
Android's Unknown Tracker Indication
According to the provided search results, when Android discovers an unknown tracker, it gives the following indications:
- Notification: Android sends a notification to the user’s device, alerting them to the presence of an unknown tracker.
- Map view: Tapping on the notification opens a map view, showing the locations where the unknown tracker was detected traveling with the user’s device.
- Tracker information: The notification provides information about the unknown tracker, including its type (e.g., Apple AirTag, Chipolo CARD, etc.) and manufacturer.
- Play sound option: Users can tap “Play sound” to make the unknown tracker emit a noise, helping them locate it without alerting the owner of the tracker.
- Manual scanning: Users can also manually scan for unknown trackers by going to Settings > Safety & emergency > Unknown tracker alerts and tapping “Scan now”.
These indications enable users to identify and locate unknown trackers that may be attached to their belongings or traveling with them without their consent.
I'm not sure whether the notification is silent as I haven't yet found one!
