Display and Navigation
The phone's display is a monochrome graphic screen with a resolution of 101 x 80 pixels, capable of displaying seven lines of text. While rudimentary by today's standards, during its time, this display was adequate for reading text messages and navigating the menu. The Siemens S45 includes a navi key for navigation, which allows users to easily scroll through options and make selections, a feature that contributed to its ease of use.
