Contact Samsung Customer Services

They may agree to book it in for a repair or they may say it is out of warranty

I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.

My device is an S25 Ultra.

Hi! Welcome to the samsung members community!!

A green line normally suggests a physical fault. Often, it needs a replacement of some sort of cable or even the screen.

Go to settings > Security and privacy, and then turn off Auto Blocker. The code will work.

Then on your phone dial *#0*#- it should open a menu- click the coloured blocks at the top....if the lines remain its hardware
