But okay Google you mean my moto voice commands?Is your "OK Google" set to listen on every screen? I think that can sometimes mess with the camera, since it sets up a conflict with the microphone (which the camera uses as well, if it's on video camera mode). The other thing to check is if you have any flashlight apps installed, since they also control the camera.
Well I can say, all I do on my phone is I access the bus in my launch phrase then saying whatever command I want to into my phone.Either one. The issues I've seen mentioned before have to do with Google Now, which is still accessible on a Moto X (it's part of the Google Search app). You should be able to bring up Google Now by pressing and holding the Home button, then swiping up.
