The invention discloses a screen turn-off management and control method. The method comprises the following steps: setting a cache space of sensor resources; detecting whether the mobile terminal is performing a network call or not; detecting whether an operation of actively turning off a screen by a user is received or not in a network call process; and when an operation of actively turning off the screen by a user is received, suspending an automatic screen turn-off function of the mobile terminal, and releasing sensor resources occupied by the automatic screen turn-off function to the cachespace. The embodiment of the invention further discloses a mobile terminal and a computer readable storage medium. Therefore, sensor resources occupied by the automatic screen-off function can be released at the bottom layer in time, and resources and power consumption are saved.
