Abstract

The invention discloses a method and system for dual calibration of a proximity sensor. The method for dual calibration of the proximity sensor comprises the steps that data in a data register of the proximity sensor are read multiple times during starting of a mobile terminal, and the proximity sensor is calibrated according to the data read during starting of the mobile terminal to obtain a first calibration result; the data in the data register of the proximity sensor are read multiple times before communication of the mobile terminal, and the proximity sensor is calibrated according to the data read before communication of the mobile terminal to obtain a second calibration result; when calibration succeeds according to the second calibration result, a threshold value of the proximity sensor is obtained according to the data read before communication of the mobile terminal, and when the calibration fails according to the second calibration result and succeeds according to the first calibration result, the threshold value of the proximity sensor is obtained according to the data read during starting of the mobile terminal.

Description

technical field [0001] The invention relates to the field of intelligent terminal debugging, in particular to a method and system for dual calibration of proximity sensors. Background technique [0002] In the development stage of smartphones, the debugging of the proximity sensor (P-sensor) will encounter various problems. The assembly structure of each smartphone is slightly different, and the peripheral environment of each machine is also different during use. , so the existing P-sensor calibration can only be performed during the boot process of the mobile phone, but during the boot process, the calibration parameters will be affected by physical factors such as oil pollution, resulting in P-sensor failure or failure during the production and use of the smartphone. Call black screen and other issues. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior a...
