I don't know about pink line but I DO have problem with green line vertically going down on the right of my screen.
Is anyone having same problem? It is not causing a problem but I find it VERY ANNOYING.... DOES ANYONE KNOW the solution for this?
ALSO, I NEVER DROP IT OR DROP IT IN THE WATER, so I am really curious about why is this happening to my phone?
Just had same issue. Contacted Samsung support who have arranged for a screen replacement. But be prepared to be without a phone for up to 7 working days. But check to see if you have a support centre nearby who can replace your screen the same day.
