A system is provided including a non-transitory computer readable storage medium that causes a mobile device to store client states indicating statuses of mobile device functional components. Each client state corresponds to a functional component. A client digest of the client state is stored. A server digest corresponding to a server state and the client digest is received from a server. The server state indicates a status of a mobile device functional component. The server digest is compared with the client digest. A state request is transmitted to the server responsive to a determination of a difference between the server digest and client digest. The server state is received from the server. The functional component is enabled or disabled as indicated by the server state. The server state and digest are stored as the client state and digest respectively. Methods for control of mobile device functional components are also provided.
