Design and Build
The Karbonn A3 is a compact device with dimensions of 113 x 61 x 13.5 mm and a weight of just 90 grams, making it lightweight and easy to handle. It supports dual Mini-SIM cards, catering to users who need to manage two numbers simultaneously. Its build, typical of early 2010s smartphones, features a plastic body available in classic black or white, reflecting its utilitarian design approach. While the design lacks the sleekness and refinement of modern devices, it was functional enough for basic everyday use during its time.
