I doubt anything can be done.
The stuff is already there in your phone to listen even when not in use.
Happens all the time when you give apps permissions.
My wife's phone will pop adds all over after we discuss a topic. And that's when not in use just sitting close enough to hear.
Once adds started popping about trailer hitch mounts for dirtbikes after we discussed getting one.
Another time it was grills for the mopar roadrunner.
And once we discussed a friend that has a possum for a pet .
No shit possom adoption sites and how to care for them started popping up next time she was on her phone.
I learned from her mistakes non of my apps have permissions fo access any files.
So no updates won't and don't matter.
I did however wait till after the 20th to update this time.
But everythimg to listen or turn you in on your fone is pre installed.
Gps, mike, cell triangulation, Wi-Fi. And then people even help them out by turning on permissions when they want to access certain features.
Now think about all the google, amazon, apple, and voice remotes and other crap voice activated people have around their house.
Big brother is watching & listening.
