Abstract: A terminal and a recording method of the terminal are presented. The terminal includes one or more processors and a memory storing computer readable program, where the one or more processors is configured to monitor call trigger event, and when the call trigger event is detected, trigger the call unit to switch a terminal status; control switching of the terminal status; and initiate a recording operation to start recording of the current call when the terminal status controlled by the call unit is switched to the calling state related to the call trigger event. If a call is performed with the terminal and recording is needed, a recording operation is automatically initiated according to a one-off event trigger and monitoring of the terminal status, which simplifies steps of the recording operation of the terminal, improves usability of the terminal, and achieves a one-click effect of recording and calling.
