Communications device state transitions

A multi-screen user device comprising:

• a first and a second screen configured to display at least one of a first display mode and a second display mode, each display mode configured to display at least one user interface element;
• at least one sensor;
• a memory;
• a processor in communication with the memory, the first screen, and the second screen, the processor operable to:
• receive a first input from the at least one sensor indicating a position of the first screen relative to the second screen;
• receive a second input from the at least one sensor indicating a movement of the first screen relative to the second screen;
• determine a state of the device based on at least one of the first and second input;
• and
• control, based on at least the state of the device, at least one of:
• i) the at least one user interface element of each screen and ii) the at least one of a first and second display mode of each screen.

A non-transitory computer readable medium having stored thereon computer- executable instructions, the computer executable instructions causing a processor of a device to execute a method for controlling a multi-screen device, wherein the device has at least a first and second screen, wherein each of the first and second screens are configured to display at least in a portrait mode and a landscape mode and configured to display at least one user interface element, the computer-executable instructions comprising:

• instructions to receive a first input from the at least one sensor indicating a position of the first screen relative to the second screen;
• instructions to receive a second input from the at least one sensor indicating a movement of the first screen relative to the second screen;
• instructions to determine a state of the device based on at least one of the first and second input;
• and
• instructions to control, based on at least the state of the device, at least one of:
• i) the at least one user interface element of each screen and ii) the at least one of a first and second display mode of each screen.
