Don't know if it's still needed, but this normally is a warranty case. It's a common issue with S7 edge screens (happens way too often with new, unrepaired S7's as well). Samsung is aware, I think about 80% of the people who own this phone will at some point find themself with a purple line through their screen. Yay, guess what I am looking at while typing this.. If you press lightly underneath the top speaker of your phone, the line will disappear. Chances are it will (sometimes immediatly) come back at some point though.
