The Nokia X is based on the Lumia and Asha design languages and features a clean and minimalist look with amazing build quality. At first sight, the Nokia X looks to have a unibody construction, however, it does have a removable back cover which encloses the sides completely leaving no gaps or cracks in the phone. The Nokia X is available in Black, White, Red, Green and Cyan and has a soft-touch matte finish for each of them, unlike that on certain Lumia smartphones such as the 520. The front of the Nokia X is dominated by the 4.0″ IPS LCD screen while the rear features a 3 megapixel camera and a speaker grille. The right side of the phone has the volume rocker and the power/lock key while the left side is completely free from buttons and has a clean look. The top of the smartphone houses the 3.5mm headphone jack while the microUSB port for charging and data transfer lies at the bottom.
