Abstract: A signal distribution circuit including an equalization circuit, a signal distribution part, an operational amplifying circuit, a feedback circuit, and a time sequence circuit. The equalization circuit is configured to collect an initial broadband signal. The signal distribution part is configured to distribute a first-stage broadband signal resulting from amplitude attenuation process to obtain a plurality of same second-stage broadband signals. The operational amplifying circuit is configured to perform amplification processing on the second-stage broadband signal obtained after distribution to obtain a third-stage broadband signal. The feedback circuit is configured to feedback the third-stage broadband signal to the equalization circuit. The time sequence circuit is configured to adjust an amplification gain of the third-stage broadband signal, and transmit the third-stage broadband signal to an analog to digital converter.

Abstract: A method for displaying different application shortcuts on different screens includes displaying, by a terminal, a first home screen, where a docked bar on the first home screen includes a first application icon corresponding to a first application, automatically determining, by the terminal, a second application that meets a preset condition, and replacing the first application icon on the docked bar on the first home screen with a second application icon, where the second application icon corresponds to the second application, and the preset condition is at least one of an application that is most frequently used, an application that is latest installed, an application that is latest updated, or an application that is abnormally exited.

Abstract: A search method includes obtaining, by a first terminal, a first key word from a user; searching, by the first terminal based on the first key word, the first terminal for a first search result associated with the first key word; sending, by the first terminal, a first search instruction to a second terminal (the second terminal is a terminal in a device group to which the first terminal belongs), where the first search instruction carries the first key word, to trigger the second terminal to search the second terminal for a second search result associated with the first key word; obtaining, by the first terminal, the second search result from the second terminal.

Abstract: A positioning method and apparatus include obtaining, by a terminal, an outdoor positioning result using an outdoor positioning service, attempting, by the terminal when information about a satellite that provides the outdoor positioning service meets a preset condition, to obtain an indoor positioning result using an indoor positioning service, where the preset condition indicates that the terminal has an indoor positioning requirement, and switching, by the terminal, from the outdoor positioning service to the indoor positioning service when the indoor positioning result is successfully obtained.
