Lock Symbol When Pressing Back Button

[Android Central Question]

I have a galaxy note 5 and for some reason when im playing a game i used to be able to click the back button when i wanted to skip an ad. Now when I do that a lock symbol shows up. Any ideas why? The back button works on other apps like instagram. This has only been happening for a couple days now. I have had this game for a week and it never did this before.

Welcome to Android Central! Maybe the ad network figured out that people were able to skip ads, and corrected that. It would be in their best interest to patch that.

There should be an orange button in the corner of your screen when playing a game. Hit that, and a black thing will come up. Turn off "lock back button" and "lock recents key." Hope this helped if I wasn't too late!
