Screen extinguishment control method and control device for mobile terminal

Abstract

The invention discloses a screen extinguishment control method and control device for a mobile terminal. The screen extinguishment control method for the mobile terminal comprises the steps of judging whether a distance sensor for controlling a screen extinguishment operation is abnormal or not when a call is put through, wherein when the distance sensor is abnormal, the distance sensor cannot control the screen extinguishment operation effectively; starting timing when the call is put through if the distance sensor is abnormal; and carrying out the screen extinguishment operation when the timing duration is greater than or equal to a preset value. According to the technical scheme of the method and the device, whether the distance sensor is abnormal or not is detected when the call is put through, and the screen extinguishment operation is carried out when the distance sensor is abnormal and the timing duration reaches the preset value, so the condition of a misoperation due to the fact that the screen of the mobile terminal cannot be extinguished in a call process because the distance sensor is abnormal can be effectively prevented from occurring.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a screen-off control method and control device for a mobile terminal. Background technique [0002] At present, mobile terminals have more and more sensors, and these sensors undertake many core functions, greatly improving user experience. The distance sensor in the mobile terminal mainly serves functions such as call and holster mode. For example, during a call, the distance sensor will detect the distance between the user's skin and the mobile terminal. When the distance is less than a certain threshold, the mobile terminal will automatically turn off. screen, to avoid false touches caused by the user's face being close to the touch screen, and also save power; when the distance is greater than a certain threshold, the mobile terminal will turn on the screen again so that the user can continue to operate the mobile terminal. Similarly, by judging the dist...

Problems solved by technology

[0003] However, in existing mobile terminals, the bright and dark screen control in call mode depends on the recognition of the distance by the distance sensor. If the distance sensor is poorly sensed or damaged, the distance judgment is no longer accurate, and the automatic bright and dark screen function of the call will be completely disabled. Ineffective, which will cause misoperation due to face touch during the call, seriously affecting the user experience
