Among the many leaked screenshots, videos and lists of specifications for the Nexus 5, the most interesting anticipated feature to me is the rumored “always listening” functionality. After all, most of the hardware and user interface tweaks are expected improvements in Google’s flagship phone: a better camera with optical image stabilization, transparent notification bar and speedy Snapdragon 800 chip wouldn’t be surprises. As the Moto X and Moto Droid Ultra phones show, however, there’s real Google innovation going on when it comes to turning a smartphone into a hands-free personal assistant. That’s why the suggestion of touchless controls on the Nexus 5 from TuttoAndroid, an Italian blog with loads of reported Nexus 5 and Android 4.4 information, has me intrigued and expecting the feature to be a highlight of both the Nexus 5 and the next version of Android.
