Display
Equipped with a CSTN display, the Siemens AP75 showcases 65,000 colors, which was standard for many feature phones at the time. Its 128 x 128 pixel resolution delivers what is necessary for viewing basic content and navigating through menus. The display size and resolution are modest, reflecting its function-focused design. A notable feature is the 5-way navigation key, which enhances usability by allowing straightforward navigation through the phone's interface.
