Abstract

The invention discloses a method and a system for avoiding the call-up malfunction. The method comprises the following steps of: S1, continuously detecting the proximity or distant state of an obstruction by a proximity detector; S2, when the obstruction is detected to approach, uploading the proximity state to an upper layer in a drive program; S3, when the proximity sensor detects that the obstruction is far away, increasing the transmission power of the proximity sensor without reporting the distant state; S4, judging whether the transmission strength exceeds the set threshold value; and S5, if the obstruction is nearby, enabling the proximity sensor to stop reporting the distant state, and lightening a screen after the proximity sensor reports the distant state if the obstruction is far away. The invention is combined with a touch screen to process the problem; when the proximity sensor is exposed, the transmission power of the proximity sensor at the moment is increased, and therefore whether a mobile phone is still near the face can be judged; if so, the screen is not lightened; and therefore the malfunction can be reduced to a large scale.

Description

technical field

[0001] The invention relates to the technical field of mobile phones, in particular to a method and system for preventing misoperation of calling. Background technique

[0002] When you put the mobile phone next to your ear to make a call, if the proximity sensor detects that there is an object blocking it, the screen will be turned off and the touch screen will be turned off at the same time to prevent misuse (for example, the face touching the touch screen causes the phone to hang up). At present, the screens of many smart phones tend to be larger and larger. At the same time, due to production and processing costs and other issues, the proximity sensor is often not located in the center above the mobile phone touch screen, but to the left or right. When many users make a call, due to some conditions in the external environment (for example, it is relatively noisy), they will put the mobile phone next to the ear, and will unconsciously adjust the position o...
