Why is my screen flickering and showing a thin green line at the top of my screen?

[AC Question]

My Samsung Galaxy 7edge Started showing a thin horizontal line at the top left corner and started flickering ...did it break already? Can I fix it ? Help!!

It may be impending screen failure. Warranty should fix.

Did you drop it?

The green line on my screen is not flickering it's a steady green line
