Second: you may be under the impression that the green line in LCDs is something Samsung does intentionally - we can assure you that we don't. Devices may fail due to any number of factors, such as mishandling, accidental drops, or software issues.
Greeen lines are also not exclusive to Samsung. Other big brands also have it. Personally I experience it on my Galaxy Note 20 Ultra and to be honest it fixed itself up via OS update. It really varies from device whether it be a software or hardware problem.
