One solution is screen replacement

Samsung gives free screen Replacement to device's getting green line issues.
You can try it in different services centres...

I have some solution for your problem.

Restart your phone. This may be a simple fix for a temporary software glitch.

Boot your phone into Safe Mode. Safe Mode disables all third-party apps, so if the green line is caused by a problem with an app, this will help you to identify it. To boot into Safe Mode, hold down the power button until the power menu appears. Then, press and hold the "Power off" button until you see "Safe mode" appear.

Update your phone's software. Samsung may have released a software update that fixes the green line issue. To check for updates, go to Settings > Software update.

Factory reset your phone. This will erase all of your data, so make sure to back it up first. To factory reset your phone, go to Settings > General management > Reset > Factory data reset.

Contact Samsung support. If you've tried all of the above and the green line is still there, you'll need to contact Samsung support for further assistance.
Give a thank if any one works for you.
