3000R curvature overview and advantages



             In geometry, the radius of curvature, R, of a curve at a point is a measure of the radius of the

             circular arc which best approximates the curve at that point. It is the inverse of the curvature.

             So, higher the number lesser the curvature, lower the number rounder the curvature.



image Advantages of 3000R curvature


            Model types featuring back cover curvature enable smoother ergonomic finger movements and

            are stronger against impacts. You will feel the difference when moving your fingers up and down

            the phone or even just holding it. The curved structure helps absorbing crash impact forces from

            different angles thus showing better durability.
