Google's Nexus 5X literally gave me a hand, in that it's a smaller one-hand-friendly Android phone, freeing up me from last year's two-handed clunker, the Nexus 6.Its size is smaller, but the Nexus 5X specs are beefed up, for the most part. It carries a faster processor, USB-C port and far superior camera that Nexus phones have sorely lacked.It delivers Android Marshmallow, the new update to Google's mobile operating system. It's the best way to get features like Google Now on Tap and the battery-saving Doze mode right away.
