  • This type of lost device search service assumes that an electronic device capable of direct communication with the server, such as a smartphone, is lost, so it cannot be used with devices (such as earbuds) that can be paired with a smartphone via short-range communication such as Bluetooth but do not have the ability to directly communicate with the server.

If the lost device finding service is restricted while the processor is in the sleep mode to minimize battery consumption of the electronic device, the accuracy of the lost device finding service will be reduced because the electronic device will not be able to receive a packet containing identification information of the lost device from the lost device even if the lost device is present around the electronic device.
