Suddenly after using the device for about 10 days, started noticing a thin 1-2 mm Green line in the upper part of my inside display. First I thought it to be app specific but then noticed that it was happening on the display and I filtered out that it was indeed a hardware/display issue.
I did some Googling and tried doing a Factory Reset based on some suggestions but that did not help. Ultimately I decided to return it back to Samsung. I always appreciate Samsung engineers and the innovation they do but just want to make sure that they know if this really is a display issue that they need to fix or could be a manufacturing defect.
