I only have a screen protector. i didn't get a case yet. It's challenging to describe the problem. It's not really a click - its more of something inside of the phone on the lower left corner - shifting or moving when I tap on something.....for instance, if I am on instagram and and tap a "like" the movement in the phone happens. I don't want to say a bang.....because the phone is so slim and there isn't a noise - it's a movement, like a jogging of something I have never experienced this before, so it's challenging to describe.
