Design and Build
Physically, the BLU Quattro 5.7 HD is a hefty device, with dimensions of 161.2 x 82.9 x 10.6 mm and weighing in at 243 grams. Its considerable weight is one of the aspects that users immediately notice, potentially hinting at a robust build. The thickness of 10.6 mm, while fairly standard for the era, coupled with the larger screen size, positions it as a multimedia device. Employing a Mini-SIM card, the design choices reflect the norms of smartphone standards from the early 2010s. Its black color provided a sleek and professional appearance, resonating with consumers favoring minimalist aesthetics.
