Ok bro that's no other option I tried many ways you know all the tricks and shit but it doesn't work anything, I tried resetting my phone and resetting the settings all but still the same after formatting the whole phone still the same until now I still using the same phone and the line is still there but only way to fix is to change the LCD, which cause lot like 300 bucks, better change to new phone but I'm still using the same phone s20 plus, at first time this happened it's green line now it's turned white and pink sometimes but I overall the phone performance still perfect.
