Abstract

The present invention belongs to the field of communications technologies, and discloses a method and an apparatus for preventing a touchscreen misoperation. The method includes detecting whether an object exists within a preset distance facing a touchscreen of a mobile terminal and detecting light intensity of an environment in which the touchscreen is located. The method also includes detecting whether an angle between a plane on which the touchscreen is located and a horizontal plane falls within a preset angle range. Additionally, the method includes setting the touchscreen of the mobile terminal to a touch-disable mode if an object exists within the preset distance facing the touchscreen of the mobile terminal, the detected light intensity is less than preset intensity, and it is detected that the angle between the plane on which the touchscreen is located and the horizontal plane does not fall within the preset angle range.

a memory storage comprising a program; and

one or more processors in communication with the touchscreen, the proximity sensor, the ambient light sensor, the angle sensor, and a non-transitory computer readable storage medium, wherein the one or more processors execute the program to;

detect that no user operation instruction is triggered on the mobile terminal during a first time period;

based on the detection, determine that all of the following conditions are continuously met during a second time period, wherein the conditions comprise;

detecting that the object is within the preset distance facing the touchscreen, detecting that the light intensity is less than a preset intensity, and detecting that the angle between the plane on which the touchscreen is located and the horizontal plane does not fall within the preset angle range; and

based on the determination, set the touchscreen of the mobile terminal to a touch-disable mode.

7. The mobile terminal according to claim 6, wherein the one or more processors further execute the program to:

detect a touchscreen enable event of the mobile terminal;
