Navi-Key The Navi Key is a concept which significantly reduces the number of keys on the phone's key pad. The user interface of the phone has been designed to follow the intuitive logic of the user. Most of the functions can be performed by just pressing the Navi Key. The concept has first been successfully implemented in the Nokia 3110. The most distinctive feature of the new Nokia 5110 is its smart menu system.
All options are in plain text, which makes using the phone extremely uncomplicated.
The large full graphics display of the Nokia 5110 features a dynamic font size that adjusts automatically for ideal viewing based on the number of digits on the screen. The special 'jumbo font' mode is clear and visible even from a distance. The stylish, slightly curved shape of the phone and the keypad layout enable comfortable one-hand operation.
