It's going to be complicated because you have 2 options

either send in your device to your Local support or whenever you can, repair the device with PCC

you could try this 

settings > language & input > google voice typing > OK google detection > turn it off and see if that helps

How it work the Google detection function?

I've seen users that had issues with OK Google and their camera, disable it and report back
