<p>A UI theme is a customized graphical user interface (GUI) that replaces

the phone's default look, and it is used to change the appearance of the user

<title>Simplified illustration of the UI theme concept</title>

</fig>

<p>UI themes give the UI theme designer a freedom to design a unique GUI,

and by designing backgrounds and icons, the result can be very different from

the default settings.</p>

<p>A good GUI has consistent metaphor. When designing UI themes, the UI theme

designer should make sure that the user interface supports the user's aim

and does not mislead the user. It is also good to remember that even though

the new look and feel offered by a UI theme would be fancy and exciting, the

general positive user experience will fade if the performance of the terminal

suffers because of a too large UI theme package file size.</p>

<p>To ensure a consistent look and feel in all applications, it is recommended

for the application UI designer to use the UI components that support UI themes.

In case application uses UI components that the UI theme does not support,

the factory default of the missing items is used.</p>

<p>A UI theme designer can decide which elements belong to a UI theme package.

It is possible to design a UI theme that uses the default UI components of

the phone together with components belonging to the UI theme.</p>
