Design and Build
The BenQ P31 boasts a compact design typical of early smartphones, with dimensions measuring 118 x 52 x 17 mm. The phone's weight, at 150 grams, gives it a sturdy feel without being overly cumbersome. Designed to use a Mini-SIM, it fits securely into the phone's form. The aesthetics are plain but functional, aligning with the standards of mobile design of its era.
