I took the battery out and saw the layer of pink underneath had some scratches in it that are showing black stuff underneath. I cant tell if this is a part of the screen unit or just a material to seperate battery from screen. Will that being scratched cause any issues? Update (07/31/2017)

this is a copper iodizing on a layer of tape behind the LCD. this is nothing to worry about, and will not cause issues with your phones function
