For the last 2 months or so, about one in 10 times that I unlock my phone, as soon as it passes the lock screen I'm greeted with a full page pop up ad. The ad is always for some google-looking app and is presented by Google adsense. I have gone into my Google account and removed as much targeted advertising as I can but 1 in 10 times is getting very annoying. I don't recall installing any new apps in that time so I don't know how to stop these ads.
Can anyone please help
