I have this weird lock icon on the top right of my screen. I have tried everything i could think of to get rid of it but im out of ideas. If anyone knows how to help me thank you because it is really bothering me!

Welcome to Android Central! Basic question--is that icon possibly a part of the wallpaper, which could have happened if you took a screenshot to create that wallpaper?
