Walton Primo S7 is Walton’s first smartphone with waterdrop notch design which makes this device a special choice for Walton fans. The U shaped notch, 6.26 inches huge screen, 8.2 mm slim body and a glossy gradient back gives a great impression about its outlook. The IPS display resolution is HD+. There is no special protection such as Gorilla Glass which can be seen as a drawback.
