Screen display, screen size, processor race..now what? Thickness comparison of course. Apparently rumors said that Samsung Galaxy S III will have 7mm thickness, which thinner than Motorola Razr who has 7.1mm waistline. However, Huawei Ascend P1 S still winning by having 6.7mm thickness.
However rumors stated that Samsung Galaxy S III will allegedly have the same camera 'hump' found on the S II, which make the thickness not uniform.
