Hi, my partner bought me a Samsung Galaxy Note 3 for my birthday last year. In the last couple of weeks thin black lines have started appearing.(left to right across the screen) I can still operate my Note 3, unlock, type messages, play games etc. I have noticed in areas where they are concentrated, that anything that is black (like password keyboard) you see the colour of the screen behind it. Is there anyway to fix this? or do I need to get a new phone?
