Smart Design The beauty of what we've engineered is to give you the slimmest feel in your hand without compromising the big screen size. The elegantly curved front and back fit in your palm just right. It's as beautiful to look at as it is to use. We spent a long time perfecting the curves of the Galaxy S7 edge and S7. Using a proprietary process called 3D Thermoforming, we melted 3D glass to curve with such precision that it meets the curved metal alloy to create an exquisitely seamless and strong unibody. The dual-curve backs on the Galaxy S7 edge and S7 are the reason why they feel so comfortable when you hold them. Everything about the design, from the naturally flowing lines to the thin form factor, come together to deliver a grip that's so satisfying, you won't want to let go.
