If you had the screen replaced by either the manufacturer or a local tech you paid to do it, have them refix it for you. You shouldn't' have problems when they have replaced it for you.

Now if you did the replacement yourself, it could be a faulty part, or there is something loose inside.

I also have an S4 and although I've never broken or replaced my screen, it suddenly started doing the exact same thing about a week or so ago. Could it be a glitch in a recent software update?
