Full-Screen Mode

Unstructured screens can be displayed in full-screen mode. (See for more information on unstructured screens, including when an app 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: Java graphics bulb1_icon.gif 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 app, 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: Java graphics bulb2_icon.gif 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: Java graphics bulb2_icon.gif 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.

app 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 for more information.)
