1. A mobile terminal control method, comprising: acquiring, by a mobile terminal, root-privileged system permission of an operating system installed on the mobile terminal; receiving, by the mobile terminal, a connection request from a remote control device via a server that is communicatively coupled to the mobile terminal and the remote control device, wherein the connection request is to establish a direct connection to the mobile terminal; in response to receiving the connection request, providing, by the mobile terminal, authentication information to the server, wherein the server is configured to authenticate the connection request based on the authentication information; and in accordance with a successful authentication of the connection request performed by the server: establishing, by the mobile terminal, a connection to the remote control device, wherein the connection grants the remote control device the root-privileged system permission of the operating system installed on the mobile terminal; receiving, by the mobile terminal, a hardware parameter request from the remote control device after the mobile terminal establishes the connection to the remote control device, the hardware parameter request being used for requesting the mobile terminal to send a hardware parameter of the mobile terminal to the remote control device, wherein the hardware parameter includes a screen resolution of the mobile terminal; sending, by the mobile terminal, the hardware parameter to the remote control device on the basis of the hardware parameter request, wherein the remote control device receives the hardware parameter and generates a virtual screen of the mobile terminal on the basis of the hardware parameter, and the remote control device sends a remote control instruction to the mobile terminal by triggering the virtual screen, and wherein a resolution of the virtual screen of the mobile terminal is the same as the screen resolution of the mobile terminal; receiving, by the mobile terminal, the remote control instruction from the remote control device, the remote control instruction being an instruction recognizable to the operating system of the mobile terminal, and the remote control instruction being used for remotely controlling the mobile terminal; and recognizing, by the mobile terminal, the remote control instruction by using the operating system, and executing an operation corresponding to the remote control instruction on the basis of the root-privileged system permission.
