4.3 Full-Screen Mode
Unstructured screens can be displayed in full-screen mode. (See Chapter 10 for more information on unstructured screens, including when an application might use full-screen mode.) In full-screen mode, the MIDP implementation does not show any title or ticker, but it might still show indicators.
MIDP Implementors
Strongly Recommend:
 Do not allow full-screen mode to take over any area used to display security-related information, such as a trust indicator. If your implementation gives this area to the application, a MIDlet in full-screen mode could display its own trusted icon and trick the user into thinking that it is trusted when it is not. Recommend:
 If your screen layout includes labels for soft buttons, do not hide them in full-screen mode. If you do need to hide them, display them in response to a user pressing either soft button. Recommend:
Although you must not display the title when an unstructured screen is in full-screen mode, you can use the text of the title for related items, such as system menus.
Application Developers
Consider:
You can change an unstructured screen to and from full-screen mode at any time. (Changing to and from full-screen mode at arbitrary times isn't a good idea, however; see Chapter 10 for more information.)
