Haitu wants to know if you can say something like "Ok Google" and have the phone wake up without having to touch anything like the Moto X. Unfortunately, people are reporting I'm other threads that this feature is not available.
All the 3rd party apps I have tried are extremely slow compared to my moto x or my tablet running Google Now Launcher. Its a nice feature, but dont find myself using it that much, and its more of a gimmick.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
