Made from Magnesium, the device weighs only 162g. Its edges are only 4.6mm, which is pretty thin if compared to the iPhone 5S' is 7.6mm. With a combination of Matte and Glossy materials the smartphone is less distracting from the front, and more captivating from the sides.
The OnePlus One features a 5.5-inch full HD resolution screen with 401ppi. And despite its big 5.5-inch display, the minimal recessed bezel means the physical dimensions of the One are not much larger as compared to other 5-inch Android phones like the Xperia Z2. That means it will be comfortable to use in one hand.
