Design and Display
The design of the O2 XDA Stealth is compact and practical, measuring 110 x 53 x 22.5 mm and weighing 140 g. It employs a Mini-SIM slot, which was the standard at the time, illustrating its compatibility with various network bands: GSM 900, 1800, and 1900. The phone has a 2.4-inch TFT resistive touchscreen display with 65K colors, offering modest visuals that are reflective of devices in the early smartphone era. Its screen resolution stands at 240 x 320 pixels, translating to a pixel density of approximately 167 ppi, which was reasonable for its time. Although small by today's standards, the screen includes a feature for handwriting recognition, catering to users who prefer stylus input.
