Your Android devices will soon join the Find My Device network

The Find My Device network is coming soon:

You can use Find My Device today to locate devices when they’re connected to the Internet. With the new Find My Device network, you’ll be able to locate your devices even if they’re offline. You can also find any compatible Fast Pair accessories when they’re disconnected from your device. This includes compatible earbuds and headphones, and trackers that you can attach to your wallet, keys or bike.
To help you find your items when they’re offline, Find My Device will use the network of over a billion devices in the Android community and store your devices’ recent locations.
How it works
Devices on the network use Bluetooth to scan for nearby items. If other devices detect your items, they’ll securely send the locations where the items were detected to Find My Device. Your Android devices will do the same to help others find their offline items when detected nearby.
You'll get a notification on your Android devices when this feature is turned on in three days. Until then, you can opt out of the network through Find My Device on the web. Your choice will apply to all Android devices linked to your gmail. After the feature has been turned on, you will be able to manage device participation at any time through the Find My Device settings on the device.
