A method of preventing loss of headphones configured to communicate with a cell phone enables an alarm setting using an app on the cell phone; the app responding by continuously measuring a received magnitude of a wireless signal transmitted between the cell phone and the headphones. If the measured received magnitude is lower than a predetermined threshold value for a first predetermined time, an audible alarm is activated at the headphones. The continuous measurement and the activation of the alarm dependent on the measured received magnitude occur automatically, independent of any user interaction with the app after the alarm setting enablement. Another method addresses a corresponding issue in a similar way to prevent loss of one earbud of a pair.

At least one embodiment takes the form of a process carried out by a given mobile radio in a group of mobile radios. The process includes broadcasting heartbeat messages in accordance with a group-wide symmetric-timing protocol and maintaining an in-range list of mobile radios. The in-range list is maintained at least in part by (i) adding mobile radios that are not already on the in-range list to the in-range list upon detecting transmissions from such mobile radios; (ii) maintaining, for each mobile radio on the in-range list, a respective keepalive timer in accordance with the group-wide symmetric-timing protocol; and (iii) removing mobile radios from the in-range list upon expiration of the respective keepalive timers. The process further includes presenting an alert via a user interface when a count of mobile radios on the in-range list falls below a notification threshold.

An electronic device controlling a screen based on a folding event and a method for controlling the same. According to an embodiment, an electronic device comprises a plurality of cameras, a foldable housing including a first hinge structure and a second hinge structure, a flexible display at least partially exposed through the foldable housing, and at least one processor provided in the foldable housing. The at least one processor is configured to display on the flexible display a first screen including an object obtained by a first camera among the plurality of cameras, detect a folding event for at least one of the first hinge structure and the second hinge structure while displaying the obtained first screen on the flexible display, and display a second screen different from the first screen on the flexible display according to the detected folding event.

A method for receiving an emergency communication includes receiving a first portion of a first communication. The method also includes receiving a second portion of a second communication. The second communication may be a duplicate of the first communication. The method includes reconstructing the first communication using the first portion and the second portion.

Embodiments of the present invention disclose a method and an apparatus for selecting a terminal mode, and the method includes: reading configuration information when a screen wakeup instruction is obtained, where the configuration information includes information about a wearable device that is paired with the terminal; querying to determine whether a wearable device is connected to a terminal; and selecting a mode corresponding to the wearable device as the terminal model if the wearable device that is connected to the terminal as determined by the querying is the same as the paired wearable device. In this solution, a corresponding mode can be selected according to a connection status between a terminal and a wearable device, thereby enhancing an automation degree of the terminal and improving a user experience effect.

The disclosure provides methods and systems for warning users of mobile terminals during active phone calls or active data transfer that they approach certain geographical areas known as areas where active phone calls or active data transfer may be interrupted. In one embodiment, a method includes obtaining, by a processor, location information associated with a mobile terminal, determining, by the processor, that the mobile terminal approaches a particular geographical area, the particular geographical area being associated with previous dropped calls based at least in part on historical data, and, based on the determination, sending, by the processor, a warning signal to the mobile terminal for informing a user of the mobile terminal that the mobile terminal is about to enter the particular geographical area.
