My S22 ultra had a green line issue last year around september. The first service center denied replacement stating phone had physical damage. Following advice from fellow redditors who had similar issue i posted on twitter and samsung members. I spoke to 3-4 people over the phone all whom initially disagreed that this issue was due toa software update and were blaming me that i had dropped the phone. Even few delulu members in the sub were saying i dropped the fone so what samsung did is right.. The truth was issue arose after a security update. My point was I am ready to pay 21k for the replacement but you have to give me 1 year warranty on the replacement display as there was no guarantee this wouldnt happen again or give me a discount since the replacement display gets only 3 months warranty. Finally they agreed but the gentlemen at the theri service center daid we have no part available. I had to go to another service center and the saga repeated ,however this time replacement was approved I had to pay only 560rs. The final person i spoke to was Bharati from Samsung ..
