I have the s7 edge. A liquidmetal case colored to match the bezel would be an excellent accesory.
Indeed a drop of the phone would most likely damage the corning glass. A liquidmetal case would provide durability.
However, if Apple comes out with liquidmetal iPhone 8, I will be trading up. If not, I will trade up with galaxy s8 edge, and a liquidmetal case-if Li produces.
