Display
Equipped with a 2.4-inch TFT display capable of rendering 256K colors, the i-mobile 638CG provides a resolution of 240 x 320 pixels. This results in a pixel density of approximately 167 ppi, which was standard for phones of its category during that period. While the display does not boast high-resolution capabilities, it suffices for basic tasks such as reading messages and navigating the phone's menu. The screen-to-body ratio of around 31% hints at the prominent bezels ubiquitous in phones of its time, somewhat reducing the immersive experience.
