Abstract: This application provides an ambient light calibration method and an apparatus, applied to the field of communication technologies, to resolve poor user experience caused by screen dimming effect incapable of matching a current environment. The method includes: obtaining location information of an ambient light sensor; obtaining first ambient light data detected by the ambient light sensor; determining an image matting region based on the location information of the ambient light sensor; performing image matting on layers of a displayed image frame of the terminal device based on the image matting region to obtain matted images corresponding to the layers, and compositing the matted images corresponding to the layers to obtain a screenshot image; and calibrating the first ambient light data based on the screenshot image and screen brightness of the terminal device, to obtain second ambient light data. This application is applied to an ambient light calibration process.

Abstract: A method includes a second processor of an electronic device processing related information of a display screen and a touch pad. The electronic device switches, when detecting that a user starts a first touch operation, processing permission of the display screen from the second processor to a first processor, and sends first touch data of the detected first touch operation to the first processor through the second processor. The electronic device switches, when detecting that the first touch operation ends, processing permission of the touch pad from the second processor to the first processor.

Abstract: An energy-saving method and a terminal device are provided. The energy-saving method may be performed by a first terminal device, and the first terminal device and a second terminal device are bound with a one-number-multi-terminal service. The energy-saving method includes: when a condition for power saving is satisfied, performing a power-off operation on a baseband module and an AP core of the first terminal device, and controlling a Bluetooth module of the first terminal device to be in a power-on state. Because the first terminal device and the second terminal device are bound with the one-number-multi-terminal service, when a baseband module of the second terminal device is in a power-on state, the first terminal device and the second terminal device may communicate with each other by using the Bluetooth module, and a function, for example, calling, of the first terminal device is not affected.

Abstract: A page redirection method, a routing device, a terminal device and a system. The routing device receives based on a first access request sent a first access response fed back by a network server; according to a redirection determination indication, modifies a return code of the first access response and adding at least one second access address of a redirected-to page and the first access address to the first access response; and sends the first access response on which redirection processing is performed to the terminal device, so that the terminal device sends a second access request according to the modified return code, and the terminal device opens, according to a second access response returned for the second access request, the page that a user needs to access and the redirected-to page.
