Got my iphone 6 plus screen replaced?

So i jut got my screen replaced as it was completely smashed! I did notice a few minutes ago that two kind of lines appear when my screen is open and i mostly see it when i'm lookin at black photos… My iphone is bent a little at the top left corner does that effect what is happening?

Well, you maybe buy a copy screen.
Buy the original screen online from amazon, HCQS.US
