Galaxy A5 automatic goes to s cover view without s cover

Searched various places,but couldn't find the solution.
My A5 automatically goes to s cover view mode randomly. Is their any way to switch off s cover mode permanently? I have seen in many sites to disable sview/suspendwindow.apk etc. But couldn't find any of these system apps. I am running my phone in lolipop & rooted. please help.
