Question: What happens to the display contents when a Frame Element marker is reached in an SMS?
Option 1: The current frame's contents are immediately replaced with the next frame's contents after a brief, predefined delay.
Option 2: The elements from the previous frame remain on the screen until the user initiates the display of the next frame.
Option 3: All graphical elements from both the current and previous frames are combined and displayed simultaneously.
Option 4: The device automatically cycles through all available frames at set intervals without user input.
Explanation: This is correct because, once a Frame Element marker is reached, the elements currently on the screen (from the previous frame) will stay there until the user requests to see the next frame, allowing for a 'multi-page' experience.
