Im having a thin and long red line on the top of my tab.(in the screen) I plunged my tab and then I went to eat, there were 1 red line straight. Plz give me an answer and I can't remove the back cover cause my father will scold me.
If you have a straight line through the display, it sounds like it's sustained some damage. There's really not anything you can do to fix something like that. If the red line is always there, the monitor is probably in need of replacement.
But I am not sure I understood your post correctly, so, yeah.
