I have a Nexus 5X running Android 6 Marshmallow, and I want "OK Google" trained to my voice to work when the device is on but the screen is off. I also use fingerprint scanner for "smart lock"/screen lock. When I say "OK Google", the device requests a fingerprint or PIN before it will do the action requested. This renders the feature pretty useless as it's mostly a hands-free tool. (Note: "OK Google" works perfectly with no screen lock activated.)

Given that OK Google is trained to my voice only and that it is a hands-free feature, I find it strange that I can't use it that way when using the fingerprint scanner or other screen lock feature. Is there a way to do it?

I'm happy to have no screen lock but just have the fingerprint scanner turn the screen on instead, if that's possible - I find it useful when taking the device out of my pocket.

  • Can you check the setting if the "Trusted voice" is enabled on Google Settings - Voice - "Ok Google" detection - Trusted voice?

Under Security and under Smart Lock, go to Trusted voice and check the option that says Always on. That's how I got "OK Google" to work when my phone is locked. I use the fingerprint lock as well.

  • Nope, still asks for pin/pattern, even with these settings
