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.
