Terminal control method and terminal
The present invention provides a terminal control method and a terminal, and relates to the field of electronic devices. The method includes when a magnetic field sensed by a Hall device of a terminal in a standby state is less than or equal to a first preset threshold, activating a sensor of the terminal, where the Hall device is configured to sense a magnetic field generated by a magnet in a protective case of the terminal. The method also includes obtaining, by using detection data of the sensor, whether the terminal is obstructed, and maintaining the standby state of the terminal when it is obtained that the terminal is obstructed. The method and the terminal provided in the present invention are applied to the terminal.

maintaining the standby state of the terminal, in response to determining, using detection data of the sensor, that the terminal is obstructed.
2. The method according to claim 1 , the method further comprising:
changing the terminal from the standby state to a working state, in response to determining that the terminal is not obstructed.
3. The method according to claim 2 , the method further comprising:
disabling the sensor after changing the terminal from the standby state to the working state.
4. The method according to claim 1 , further comprising:
determining, using the sensor, a distance between a flip side of the protective case of the terminal and the sensor;
determining that the terminal is obstructed, in response to determining that the distance is less than or equal to a second preset threshold; and
determining that the terminal is not obstructed, in response to determining that the distance is greater than the second preset threshold.
5. The method according to claim 4 , wherein the second preset threshold is 1 to 2 centimeters.
6. The method according to claim 4 , wherein the sensor is a proximity sensor.

activate the sensor, in response to determining that the terminal is in a standby state and that a strength of the sensed magnetic field is less than or equal to a first preset threshold; and
maintain the standby state of the terminal in response to determining, using detection data of the sensor, that the terminal is obstructed.
