Mysterious Samsung phone with 2K display revealed -- if this is the Galaxy S5, we need it right now:
If there's one thing we feel confident in saying about Samsung's upcoming Galaxy S5 smartphone it's that it will have killer hardware. FoneArena points us to a new benchmark posted at GFXBench showing a mystery Samsung phone that features a 2K display with a resolution of 2560 x 1440 pixels and a 2.5GHz quad-core Snapdragon 800 processor. Given the resolution shown in the benchmark, FoneArena speculates that the mystery device might have "a 5.25-inch display since the pixel density of a 5.25-inch 2560 x 1440 pixels display would be 560 ppi." While we don't know for sure which new Samsung phone this is, it's very likely that the Galaxy S5 will at least match the specs revealed in the benchmark. Earlier leaks have suggested that the Galaxy S5 will feature a 5-inch Super AMOLED display, a 16-megapixel camera, a 4,000 mAh battery, 3GB of RAM and Android 4.4 KitKat.
