Display
Equipped with a modest 1.6-inch STN display capable of rendering 65K colors, the J210’s screen is certainly of its time. While the 128 x 128 pixel resolution doesn’t compare to today’s high-definition screens, it was sufficient for displaying essential information such as contact details and simple user interface graphics. The display occupies around 19% of the front surface, which is typical for phones of its era, as most devices then prioritized practical screen space over expansive displays.
