I did report the problem to service centre and they told its an hardware damage and only way to report it to Samsung is through a job sheet and for them to open up phone and check, it would take 3 working days and that too if we convince the customer...
IT World, Thoraipakkam, Chennai. I went there on 5ft of July to fix my power key and check if they got any notice for S22+ screen replacement scheme for green line issue and they said they received notification only for S21 FE and S22 Ultra.
I went to a samsung service centre yesterday and checked with them. Seems there's a scheme for free display replacement for S21 FE and S22 Ultra. Do go and check with your service centre soon.
