Abstract: The electronic device detects a pointing input to an edge area in a viewable screen portion on one side of a display screen of a display module, provides an affordance for changing a size of the viewable screen portion based on one or a combination of two or more of a time when a pointing input is maintained in the edge area, a moving distance of the pointing input, and a moving speed of the pointing input, and changes an area of the viewable screen portion to a size determined by the pointing input through a variable driver.

Abstract: An electronic device may include a first housing, a second housing, a hinge device configured to connect the first housing and the second housing so that the electronic device is switched from a folded state into an unfolded state, a first alloy member, at least a part of which is fixed to the first housing, the second housing, and the hinge device and which is made of a shape memory alloy material, a second alloy device, at least a part of which is fixed to the first housing and the second housing at a position different from the first alloy member and which is made of a shape memory alloy material, and a driving circuit configured to apply power to at least one of the first alloy member and the second alloy member so that at least one of the first alloy member and the second alloy member is restored. Various other embodiments may be possible.

Abstract: An electronic device according to various embodiments may include: a housing, a flexible display having at least a partial area configured to be drawn out from the housing so that a size of a visible area of the flexible display can be changed, a sensor configured to measure a length of the flexible display, a memory, a processor operatively connected to the memory, the sensor, and the flexible display.

Abstract: An electronic device includes a communication processor including a first communication circuitry, a second communication circuitry, and a temperature measurement sensor. The electronic device further includes an application processor that receives information via the second communication circuitry and determines whether to request the communication processor change modes. The communication processor receives a signal to change modes, release an RRC connection, and control the second communication circuitry to enter a sleep state.

Abstract: Disclosed is a method, apparatus, system, and/or non-transitory computer readable medium for chatting on a mobile device using an external device. A chat method performed by a mobile device configured as a computer may include receiving a transmission input request for a signal including a send message through a preset button input of an external device; receiving, at the mobile device, the signal in response to the transmission input request; transmitting the send message to at least one counterpart that participates in a paired chatroom according to the signal; and outputting, to the external device, a received message that is received as a reply to the send message from the at least one counterpart through the chatroom.
