HTC design enthusiast envisions the Samsung Galaxy S7 as the One M9's rich cousin
For those who find the gold color and shiny pattern arrangement a tad on the tacky side, Hasan made a more conservative all-black version as well. It looks like a winning candidate for being Batman's next smartphone. Just look at that black dotted pattern - it looks like kevlar armor, while the smartphone itself belongs to the Batmobile's dashboard.
Although these concepts probably won't materialize - due to their build complexity, among other reasons - they are nevertheless entertaining and feature some great ideas. The all-metal unibody build is certainly a viable way of improving the Galaxy S6's design even further.
