Abstract

The invention provides a method for dynamically adjusting a threshold of a distance sensor. The method comprises the following stepsf: when starting the distance sensor to converse, judging whether the distance sensor detects an approach state, if not, at least increasing a preset value or preset ratio to the approach state detection distance of the distance sensor one time within a preset system off-screen time T; judging whether the distance sensor detects the approach state according to the approach state detection distance after being adjusted each time, if the approach state is detected after the approach state detection distance is adjusted, switching a screen into an off-screen state from a bright screen state, and if the approach state is still not detected after the system off-screen time T is achieved, switching the screen into the off-screen state from the bright screen state. The invention also provides a mobile terminal, therefore, the problem that the distance sensor leaves out detection of the approach state when the mobile terminal converses can be avoided, so as to automatically turn off the screen, and the mobile terminal can automatically turn on the screen after the conversation is finished, so as to be convenient to use by the user.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for dynamically adjusting a distance sensor threshold and a mobile terminal. Background technique [0002] Existing smart phones and other mobile terminals enable the distance sensor by default. When the user makes a call, the mobile terminal is close to the head. At this time, if the distance sensor detects that the distance from the head is less than the predetermined proximity detection distance, the screen will be automatically turned off; After the completion, move the mobile terminal away from the head. At this time, if the distance sensor detects that the distance from the head is greater than the predetermined distance from the head, the screen will automatically turn on, which is more convenient for the user to operate and saves power. [0003] However, the existing technology does not consider that when the mobile terminal is close to the head, the dista...
