In one embodiment, when the proximity sensor 316 detects a gradual decrease in the distance between the user and the front face of the terminal 300, the processor 301 controls the touch screen 305 to switch from the on-screen state to the off-screen state; when the proximity sensor 316 detects that the distance between the user and the front surface of the terminal 300 gradually increases, the processor 301 controls the touch display screen 305 to switch from the off-screen state to the on-screen state.
Those skilled in the art will appreciate that the structure shown in fig. 3 is not limiting and that more or fewer components than shown may be included or certain components may be combined or a different arrangement of components may be employed.
Example IV
In an exemplary embodiment, there is also provided a computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements an OTA mode test method as provided by all inventive embodiments of the present application.
