Display
Equipped with a 2.0-inch TFT display, the S720i delivers 65K color representation at a resolution of 128 x 160 pixels. While the screen-to-body ratio of 28.4% might seem small by today's standards, it was adequate for the text-based functionality predominant at the time. The pixel density of around 102 ppi provides clarity for text and basic images, though it becomes limited when displaying more detailed content.
