Display
Equipped with a 4.5-inch IPS LCD screen, the T21 provided a decent viewing experience considering its era. With a resolution of 720 x 1280 pixels and a pixel density of about 326 ppi, the display was fairly sharp and clear. Though the screen-to-body ratio was approximately 64.1%, it fell in line with the typical design aesthetics of that time, lacking the edge-to-edge screen experience seen in modern devices.
