At the Google I/O conference, not only a lot of gadgets were presented, but also a useful update for existing equipment: the Find My Device network, which will simplify the search for gadgets. This is an analogue of Apple's "Find iPhone".
Although the Find My Device app itself has been available on Android devices for a long time, in the current version it is only able to roughly determine the location of devices via an Internet connection or based on their last Bluetooth connection point. This can help you find a forgotten smartphone, but an earphone that has fallen behind the sofa is unlikely.
The redesigned version of Find My Device will link all devices into a single network to provide accurate geolocation thanks to information from gadgets of different users. In other words, if your smartphone has lost the earphone, but a passerby's smartphone "saw" it, geolocation will be displayed in your application. At the same time, the data is transmitted with end-to-end encryption, so even Google will not be able to access the gadgets.
The updated Find My Device service also adds support for two new categories of devices: headphones and Bluetooth trackers. You can add any name to the beacons for a more convenient search.
It is noted that immediately after the release of the update, the Find My Device network will work with existing Pixel Buds, support for "upcoming models" of headphones Sony and JBL will add in later updates.
Support for Bluetooth beacons includes Chipolo, Tile and Pebblebee, but only new models. On the manufacturers' websites, such trackers have a compatibility bar with Find My Device.
