OnePlus One is little large and heavy device but its curved back and thin bezels makes it ergonomic. The chrome band around the front glass panel and a choice of seven diverse replaceable “StyleSwap” back panels makes the device look elegant yet attractive. One of the best things about styleswap is that you can change them according your choice. It’s a unique and bizarre but not completely unwelcome material.

On the other hand, Xiaomi Mi 3 comes with completely flat back and rounded sides. The matte finish plastic cover on the back-side could almost be mistaken for metal.
