http://www.androidauthority.com/galaxy-s6-fastest-speed-test-620274/ In a mostly real world test, Tom's Guide has proclaimed the Galaxy S6 the fastest smartphone.The LG G4, iPhone 6, HTC One M9, Nexus 6, and Asus Zenfone 2 rounded out the top six. I'm not surprised by the results because Samsung knows how to make a powerful device. I think it's most surprising that the G4 came in second, and the Zenfone 2 came in sixth. The Zenfone 2 is powered by an Intel chip and 4GB of RAM, so that's a victory for Intel. Anyways, the Galaxy S6 is blazing fast, that's for sure.
