Nexus devices running Android 5.0 will have a hands-free feature
As such, we don't know when the hands-free feature will be making its way to Nexus models. It could arrive at the same time that another pair of Moto X features comes to certain Nexus models.
One of those features is the Always On Voice Recognition that is coming to the Nexus 5, Nexus 6 and Nexus 9. With this feature, the phone or tablet is always listening for the code that turns on Google Search, such as "Ok, Google." Another Moto X feature, Ambient Display, is also on the way to the same models. The feature lights up the screen when you pick your phone or tablet off of a desk. And it also lights up the screen whenever a notification comes in.
Thanks for the tip!
