Got stuck with a Pop-up on the main screen I have Samsung Galaxy E5 (SM-E500H) with Android 5.1.1. Recently, I installed few apps and after that, I encountered an annoying little pop-up below the screen sometimes. I got into uninstalling some of those apps but the pop-up didn't go away. How can I get rid of that? More technically, how can I find out which process is the cause of that?

Thanks for all the helpful comments. Answer to: Determine which app is drawing on top of other apps? helped me a lot. I monitored the apps having special permission to put an overlay on top of other apps. I waited until the pop-up showed and with a little compare with the preceding apps list I could find the causing app. Thanks @Firelord. 

So, I want to expose the app that caused this unwanted and annoying pop-up:
