This high-end smartphone delivers a large screen and high-capacity battery in an innovative, hand-fitting design. The device has been aggressively downsized so that it is just 3 mm thin with a smooth back surface that seems to stick to your hand. Furthermore, an optimized layout and unibody construction have eliminated unnecessary parts to make possible an overwhelmingly simple, beautiful design. The frequently-used power key is made from a ceramic material that combines the beauty of a precious metal with a high level of durability.
