Abstract: Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for location-tracking wireless devices. In an embodiment, a method performed by an electronic device comprises: playing, or initiating the playing of, a sound through a loudspeaker of an accessory device via a communication link. The sound is played at a specified frequency that utilizes a frequency response of the loudspeaker (or loudspeaker plus speaker enclosure). The sound is received through two or more microphones of the electronic device and filtered by one or more filters. The one or more filters are configured to pass the sound at or around the specified frequency and to reduce masking of the sound by ambient noise. The filtered sound is associated with direction data generated from sensor data provided by one or more inertial sensors of the electronic device. In another embodiment, the specified frequency is higher than the maximum human hearing range.

Abstract: A device locator mode or find my device (FMD) mode can allow a lost, stolen, or misplaced mobile device to be located. The FMD mode can be enabled or disabled on a mobile device. Sometimes thieves or unauthorized parties attempt to disable the FMD mode. To prevent this, the mobile device can transmit a unique device identifier to a remote server. The remote server can link the device identifier to a cloud-based user account associated with the user of the mobile device. Before an FMD mode is disabled on the mobile device, before the content or settings can be erased, and/or before a mobile device is permitted to be activated/reactivated, a user of the mobile device can be challenged for the credentials of the cloud-based user account. If valid credentials are provided, FMD can be disabled, the content or settings can be reset, and/or the device can be activated/reactivated.

Abstract: Systems, methods, devices and computer-readable storage mediums are disclosed for managing location sharing requests. In various implementations, a requesting device or a server computer in communication with the requesting device, receives a location sharing request associated with a user and, in response, sends a notification to a companion device associated with the user. A location of the companion device is received from the companion device together with a list of one or more devices associated with the user that are paired with the companion device and a connection status for at least one of the one or more paired devices. The connection status indicates if there is a direct communication link established between the paired device and the companion device. A notification is sent to each disconnected paired device based on the connection status. Each disconnected device that is worn or carried by the user responds with their location.
