Why does my phobe play weird adds with no apps open?

[Android Central Question]

For the last couple of days there has been weird ads playing on my phone. It's always the same guys voice and even if I close all the apps or go back to my home screen the ad keeps playing.

Welcome to Android Central! Have you downloaded a new app of late? Some apps will contain ads and games that you have to "watch or play" before getting to the game in question. Or, have you clicked on any pop-up ads or anything of that sort recently? Try going into Safe Mode and see what happens then.
