Design and Display
The ZTE U900 features a classic design tuned to the standards of its release period. Although the device's dimensions and weight are unspecified, it follows the compact, minimalist aesthetic typical of early smartphones. The use of a Mini-SIM slot indicates the technology standard for connectivity at that time. The phone is equipped with a 3.5-inch TFT display capable of rendering 256K colors, which was fairly standard for its class and had a resolution of 480 x 800 pixels. The resulting pixel density of approximately 267 ppi provided a reasonably clear and vibrant visual experience for core activities such as browsing and media playback.
