Following years of complaints by users, Google is cracking down on Android apps that show shady ads on your lock screen, according to a new developer policy spotted by Android Police. That includes very popular ones like ES File Explorer, which has over 100 million downloads to date. They often force annoying, obtrusive and even spyware ads to pop up for games, iffy anti-virus tools and other dreck.
Google is letting some apps continue to display ads, however. "Unless the exclusive purpose of the app is that of a lock screen, apps may not introduce ads or features that monetize the locked display of a device," the new developer policy note reads. In other words, if the express purpose of the app is to be a lock screen, it can continue to annoy you with ads.
Last year, users on Reddit went so far as to build a spreadsheet of apps that exhibit the behavior, which includes the Go suite of apps (Weather, Keyboard, etc.), ES File Explorer, HiFont and 360security. On a Reddit post about the new policy (with over 1,400 comments), users noted that even smartphone manufacturers like Samsung have pre-installed apps that exhibited the behavior.
