Design and Build
The Noir X400 featured a straightforward design typical of smartphones from its time. With dimensions of 131 x 65 x 7.8 mm, the phone was relatively compact, fitting easily into the palm or pocket. Although its exact weight isn't specified, it was lightweight by contemporary standards. The device offered a dual SIM option, catering to users needing separate lines for personal and business use. The black color gave it a classic look, albeit lacking in variety. Overall, the build was utilitarian but adequate for a budget device.
