I used to be able to "OK Google" from the screen off/locked state and I can no longer do so.
In my attempts to fix it with the forums, I have noticed that when the screen goes dark or locks the "From any screen" and "Trusted Voice" sliders move to "OFF".
Settings>Lock Screen & Security>Secure Lock Settings>Smart Lock>Trusted Voice....when I tap this I see the sliders for "From any screen" and "Trusted Voice" move from OFF to ON. If I lock and unlock the phone from there I see the sliders move from OFF to ON when the screen unlocks.
It appears that the screen lock disabled both settings.
