Welcome to Android Central! Which phone? It's adware associated with a sneaky "feature" from one your apps. These are usually 3rd party apps you installed, but some preinstalled apps (like Peel Remote on Samsung phones) have also been known to do this kind of annoying thing. If you have Peel Remote, disable it. If you don't, then start uninstalling apps one by one until the problem goes away. Focus on apps like 3rd party file managers, keyboards, cameras, battery savers, and "RAM boosters."
