The invention provides a call window control method and device, a mobile terminal and a readable storage medium. The method comprises the following steps: displaying a first call window and enabling a three-dimensional
gesture recognition function after a
system in a preset mode of a preset state receives an incoming call request, and displaying a second call window comprising a first preset function option for the incoming call request after a preset three-dimensional gesture is recognized. According to the call window control method, when
call control is performed by using the call windows in the preset state, selection operation of multiple call functions can be performed through the preset function option of the second call window, and a user does not need to switch to a call application interface, so that the
operation mode of the user is simplified. The preset function option can also be expanded through
gesture recognition, so that the operation is further simplified, and the user experience is improved.
