Assalamu alaikum, there are two lines on both sides of the phone, but this is not a green line. I showed it to Samsung customer care, and they checked and said it happened because the display is turning black, the ribbon is fine, it will not increase and will remain like this, and there is a slight white shadow on one side at the top of the display, which is not a problem. Other than that, everything is ok, a very good phone, the condition is still like new, you will get 3-4 covers. F-Ok
