Display
Equipped with a 2.5-inch TFT resistive touchscreen, the ZTE X990D’s display supports 256K colors and has a resolution of 320x240 pixels, resulting in a pixel density of approximately 160 ppi. While modest by today’s standards, the screen was adequate for the phone’s functionality and intended use. The resistive touchscreen technology means navigating through menus required a firm press, differing from the capacitive screens used in more advanced smartphones that required only a light touch.
