Xiaomi Redmi K40
Xiaomi Redmi K40 is a nice upgrade to the popular K series of smartphones sold by the Chinese brand, which features a solid glass body and lightweight plastic frame. The rear panel features a minimalist look with a frosted matte finish that remains smooth and uniform throughout the body. The sides and edges have been slightly curved to make the device easier to hold, while the camera module has been flattened into a slim rectangle with curved edges and a dual-tone finish that makes it easier to blend in with the backdrop. However, the section with the lenses features a glossy black finish that contrasts nicely with the rest of the body.
