Display Characteristics
The O2 X4 comes with a TFT display capable of rendering 256K colors, a vivid palette that was quite impressive for its time. The main screen boasts a resolution of 176 x 220 pixels, ensuring clarity for basic applications and navigation. Additionally, the phone features a secondary external display capable of displaying 4096 colors, primarily used for notifications and quick previews without opening the clamshell. This innovation offers practicality in everyday use and reduces battery consumption by limiting the main display's active time.
