IPHONE 5c BARELY PICKING UP FINGERS?

So I had my screen fixed by this place called Skytree electronics and first time he fixed it the screen popped out and I got it fixed again but now when I try to unlock my screen it doesn't pick up my fingerprints but when I manage to unlock it it works fine (well sometimes it glitches) but I can also hear a clicking when I press on the screen.

Get a replacement.
