Curved or straight? Samsung's Galaxy S6 or whatever-its-called could be both, as the latest teaser shows a straight edged phone, when another from last week flaunted some curves. It boasted about the model being "crafted from the beautiful things I see around me," possibly a reference to the use of metal in the body rather than plastic. Who knows? It's smartphone PR after all, not Chekhov. Curved or straight, we expect that it'll be Exynos-powered, nearly bloatware-free and possibly packing a smaller battery. We'll find out next week at Mobile World Conference 2015, so try not to lose any sleep.
