LCD - erroneous line at the top of my screen
I have an erroneous line at the very top of my LCD (see attached pic, look at the very top of the display where there is a horizontal line, this line is actually a little more obvious in some other display situations, sorry for not having a better quality picture).
Is my LCD broken? Hardware issue? I am okay with this line being there forever, but I don't want it to spread. Will this issue spread?
My soft buttons also have a purple tinge to their after touch animations, so, I am wondering if my whole LCD screen is crumbling slowly.
It is under warranty, but rooted etc., and I don't want to go through the hassle of reverting back everything to stock and send it for repair if the LCD line issue won't spread.
What do you guys think?
