The user may have a possibility to set any image as background ‘wallpaper’ in idle.  
It is also possible to have a ‘screen saver’ application that may use the whole screen 
while the device is not used. It should be noticed, however, that soft notifications 
and other indications on screen would not be visible during this kind of application. 
Application shell 
The Application shell is the menu used for accessing all applications. Pressing the 
Application key opens the Application shell, where the user may browse and select an 
application. Applications are presented as a grid of items by default; the user can 
also choose to use a list presentation. Pressing the Select key opens an application 
and closes the Application shell. Refer to the Application handling section for 
detailed information about opening and closing applications.
