Device and method for display screen control using two processors

Abstract

Abstract A communication device comprises: a communication interface; a display screen; a first processor configured to power up according to a first power-up time, the first processor for implementing radio functionality associated with the communication interface; and a 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 first power-up time: controls the display screen to provide a first GUI displaying communication interface-related information and a power-up status of the second processor; and after the second power-up time, hand off control of the display screen to the second processor. The second processor, after being provided with control of the display screen: controls the display screen to provide a second GUI displaying the communication interface-related information and information associated with the extended functionality. Abstract the communication interface-related information and information associated with the extended 20 26 21 08 76 03 A ug 2 02 6 A b s t r a c t 2 0 2 6 2 1 0 8 7 6 0 3 2 0 2 6 A u g
