Google's Android 15 OS may introduce a "Bluetooth auto-on" feature to improve Find My Device network efficiency.

Google's upcoming Android 15 OS may include a "Bluetooth auto-on" feature that turns Bluetooth back on after a day of being manually turned off. This is expected to improve the efficiency of the Find My Device network, which relies on Bluetooth to create a mesh network among nearby Android devices for easier location of lost or stolen devices. The data transmitted over this network is encrypted for user privacy.
