Exactly it's one little spot and a short stream near the bottom left corner.
I can't feel anything under my finger if I touch the area and I don't think they are stuck/dead pixel but something else.
Clear spots are more visible with white or clear colours while on darker ones almost not noticeable.
Does anybody know what's it all about and if is there any way to fix it?
I desperately tried to take a picture of it but every picture I took doesn't have enough detail to clearly show what I'm talking about.
It happened probably after I replaced internal wifi module so I thought maybe it could be related to some screw overtightening and I tried to turn 1/4 countrclockwise screws on the area involved but nothing changed...
