Pop up ads while offline tablet is sitting idle?

[AC Question]

I have my RCA Android tablet set to sleep after 1 minute of idleness. Afterwards a pop up video ad starts playing on its own non stop until I stop it myself. It's annoying . Any guesses why?

Probably some app you installed. I would try to uninstall any recent apps to see if it fixes the problem. Otherwise, you can try to backup any important data and do a factory data reset and don't install any apps to see if you still have the same problem
