After seeking the best possible compromise for the Note 4, I chose the official solution. Not only the hulls are very likely to scratch the rating because the flute portions are fragile, but in addition they make the moving relatively coarse, it does not need to be larger.
I recommend this shell, which thickens little the Note 4 and protects the screen and the edges of everyday life. The edges are in fact wider than the rating to help protect them.
