When I try to set up voice recognition with OK Google through my Settings\Security\Smart Lock\Trusted Voice\From An Screen, my phone "listens," but then reports, "Can't use the microphone. Restart your device." Restarting does not help. OK Google is installed, and I can get it to hear me if I tap the microphone icon in the Google bar on my home screen. I also have the Moto app installed, and it works okay. Disabling Moto does not help. The last suggestion that I received was to do a factory reset, which I'd like to avoid. Thanks.
