It was widely expected that the Nexus 5 from Google would also include the always on listening feature as seen on the Moto X, since the Snapdragon S800 processor has a dedicated core for audio processing while barely sipping any power. While the Nexus 5 does have the ‘Ok, Google’ feature, it only works on the home screen, and not when the device screen is turned off.
As it turns out, there is more to Motorola’s Touchless control feature than what meets the eye.
