15. A method comprising:
a first processor of a communication device, after first power-up time of the first processor controlling a display screen of the communication device to provide a first graphic user interface programmed to display communication interface-related information and a power-up status of a second processor of the communication device, the first processor configured to power up according to the first power-up time, the first processor for implementing radio functionality associated with a communication interface of the communication interface, and the second processor configured to power up according to a second power-up time longer than the first power-up time, the second processor for implementing extended functionality as compared to the first processor;
the first processor, after the second power-up time, handing off control of the display screen to the second processor; and
the second processor, after being provided with control of the display screen, controlling the display screen to provide a second graphic user interface programmed to display the communication interface-related information and information associated with the extended functionality,
wherein the communication device further comprises a communication bus, wherein the first processor and the second processor are further configured to communicate with each other via the communication bus, and
the method further comprises: the second processor, during the second power-up time: providing the power-up status of the second processor to the first processor via the communication bus.
