Abstract: A method for recording a multimedia call with common consent via an instant communication software program is proposed. Via execution of the software program, when an electronic device makes a multimedia call to another electronic device, a recording notification is provided to said another electronic device for notifying a user of said another electronic device that the multimedia call would be recorded. After the multimedia call has ended, one of the two electronic devices generates a recording file for the multimedia call, and transmits the recording file to a virtual chat room created for the two electronic devices.

Abstract: A method for scheduled transmission of a message is to be implemented by an instant messaging (IM) device, and includes: executing IM software and providing a graphical user interface (GUI) which includes a chat interface for a chat session, the chat interface being established in advance by the IM software; when it is determined that a message is inputted in an input field of the chat interface and that a prearrangement icon of the chat interface is selected, presenting a date-and-time picker in the GUI for setting a scheduled time; generating a scheduled task when it is determined that the scheduled time has been set; and sending the message corresponding to the scheduled task to the chat session when it is determined that the scheduled time corresponding to the scheduled task has arrived.

Abstract: A method of automatically playing a voice message is proposed to be implemented by a smartphone that executes an instant communication software program. The method includes: opening, by the smartphone, a chat window for communication between a user of the smartphone and a chatting target; and upon determining that there is at least one voice message not having been played before in the chat window and, based on a signal provided by a proximity sensor near a receiver of the smartphone, that there is an object close to the receiver, automatically and audibly outputting the at least one voice message using the receiver.
