So I had an S4 space gray aluminum model that I just traded up for the S4 SBSS model. For some reason, and I know it’s just optics because the casing size is the same on both models, the SS model seems thicker where the aluminum model seemed thinner. I was just in a store as well and thought the same thing seeing the space gray aluminum sitting next to the SBSS model. Again, I know they are the same size but does anyone else have this perception?
