Series 90 (software platform)

The Series 90 (formerly Hildon) is a platform for mobile phones that use Symbian OS.

[1][2] Although only one production Series 90 device was made, a form of the GUI continued on as Nokia's Hildon user interface in the Maemo shipped with Nokia Internet Tablets.

It has been modified to be controlled entirely through the touchscreen, supplemented by the 77x0's seven hardware buttons and rocker-dial.

The Nokia 7700, which was never released, had only an on-screen keyboard for text input; the 7710 added basic handwriting recognition.

Applications now have only a single menu tree, accessible from the title bar at the top of the screen; there is no Exit or Quit option in most apps; and a button bar has been added to the right hand side of the screen, resembling that of the Nokia Communicator smartphones.
