Yes. The low level API's give application developers complete control over the screen real estate allocated to the application. The low level APIs allow the application draw its own graphics and to
respond to event inputs from the device keypad. Devices are required to have a ITU-T keypad, which has buttons for 0-9, *, and #. The low level APIs give the application developer more control
over what the user sees but make the application less portable.
Hope this answers the question,
