Design and Display
The design of the Karbonn K440 is simplistic and functional. Measuring 119.5 x 54 x 13.5 mm, it is compact and fits comfortably in the hand, although it lacks the sleekness of more modern designs. The phone features a 2.6-inch TFT display, capable of rendering 256K colors, which, while modest by today's standards, is adequate for basic tasks such as making calls, browsing contact lists, or reading text. The screen resolution of 240 x 320 pixels results in a pixel density of about 154 ppi, which ensures text and images are sufficiently sharp for day-to-day use.
