AutoVoice Ok Google (not assistant) on the lockscreen

Hello!
I have a problem when I try to execute "Ok Google" commands with the screen locked. Google tells me: "actually I can not do that while the device is locked"

Is there any solution?

Thanks in advance!

 

You need to unlock your bootloader

 

Hi Kiran! And thank you for your answer, but my bootloader is already unlocked.
I´m using PureNexus Rom on my Nexus 5x

 

No, I mean with "Autovoice recognized command"

 

did you install google as system app?
I used to get this message from google when I was on MM. After I installed google as system app and give proper permission I got over it.. try it may help you too

 

Wow, that's interesting, but how do I know if it's already installed as a system app?

 

If you are rooted your device, then you can use your favourite root browser to paste the apk file in system > priv-apps > here and change the permissions (rw)..
if you wanna know its a system app or not simply try to uninstall it if its a system app it wont allow to uninstall

 

Ok, but it seems to be already a system app
