Yesterday I went to a repair shop to get my galaxy s4 screen replaced because I had dropped it and the inside screen had cracked. The repair took about 1 hour and cost 130 pounds. When I got home I noticed there were lots of thin black lines running across the screen depending on the brightness. Ive tried turning the brightness up and down and I've googled this problem all day.
Does anyone know how to fix this or know the cause of the problem?
