OP, this is absolutely TRUE!

I've stated this before and even the mobile app states that it will have control of your camera and mic.

Here's a snap shot of the 42 screens I captured that list the terms of the app for android.

Look at the last image to the right, it states, "record audio". [link to postimg.org]

This has happened TIME AND AGAIN, when I was JUST talking about something and upon going into google, I will start typing something and there is the EXACT thing I was just talking about.

I mean, really obscure things at times too!

Good catch OP. I think I've mentioned it on here before but, I'm not a registered user and my stuff seems to get glossed over as a result.
