回复： Why does my screen has a green vertical line on left sideIf your phone is always on let it cool down. If you don't want to turn it off put it in the refrigerator for a couple of minutes.
回复： Why does my screen has a green vertical line on left sideI have two lines 1 green on the left side and one red on the right side. On the right side if I put pressure all the way on the top of my phone the red line will go away but not permanently. On the left side if I put pressure on the top of my phone it doubles or triples the green line. So right now I have one green line. Update (09/01/2018): I have the green line on the left side of the screen also. I also had the red line on the right side of the screen. For the red line I put pressure with my thumb on the top of the phone and it goes away only temporarily. For the green line I put my phone in the freezer for 3 or 4 minutes and cold it down and the green line disappeared. But I don't know how long it will last yet.
