A device control method and an apparatus are provided. The device control method, applied to a main control device, includes: receiving a control instruction; sending a first signal to candidate controlled devices according to the control instruction; receiving second signals sent by the candidate controlled devices in response to the first signal, where the second signal carries a transmit power value of the candidate controlled device; determining a candidate controlled device corresponding to a minimum signal attenuation value as a target controlled device according to received power values for receiving the second signals by the main control device and the transmit power values of the candidate controlled devices carried in the second signals; and sending the control instruction to the target controlled device.

Device control method and apparatus

Method and apparatus for mode switching are provided in the disclosure. Aspects of the disclosure provide a method for switching a display mode of a device. The method includes receiving an intensity value of ambient light when the device is in a first control mode in which backlights of a liquid crystal display screen are controlled in order to control a display brightness of the liquid crystal display screen, determining whether the intensity value is less than a predetermined threshold, and when the intensity value is less than the predetermined threshold, controlling the device to enter a second control mode in which voltages provided to data lines of the liquid crystal display screen are scaled according to a ratio in order to control the display brightness of the liquid crystal display screen.

Method and apparatus for display mode switching based on ambient light

The present disclosure relates to methods and devices for identifying short messages received by mobile terminals as being from pseudo base stations, wherein, the method comprises: obtaining feature information of the short message when the mobile terminal receives the short message, wherein the feature information includes content information; judging whether the short message is suspected to be an annoying short message based on the feature information; obtaining, when it is judged that the short message is suspected to be an annoying short message, an operation time of when the mobile terminal performed a cell reselection operation with a location area update, wherein the operation time is closest in time to when the mobile terminal received the short message; determining whether the short message is an annoying short message from a pseudo base station based on the operation time. In the technical feature, information security of user terminals may be enhanced.
