Display
The Duo features a 2.2-inch TFT display that showcased 256K colors. While its screen size might seem small by today's standards, it was quite common back in 2007. The resolution of 240 x 320 pixels provided adequate clarity for basic phone functionalities. However, the screen-to-body ratio of around 29.4% meant that the display was surrounded by substantial bezels. This display was best suited for text and basic graphics rather than multimedia.
