My screen goes black and at the bottom of the screen it says opt out. how do i get rid of this?

[Android Central Question]

Other pop ups come up all the time as well

Don't touch any part of the popup, not even the "opt out" bit (especially the opt out bit).
Back out of the screen using home button. Try again.
