Whenever I connect by sony xperia z ultra android lollipop to a wifi, and if I lock and unlock, an ad comes out of nowhere. This happens even if the wifi is not connected to the internet. The ad covers the entire screen. Any fixes?

Welcome to Android Central! So this never happens if you're using mobile data alone? Regardless, the ad is due to some kind of adware that you probably installed inadvertently alongside some other app. Uninstall apps one by one until the problem goes away.
