Samsung — Samsung S20 plus green vertical line issue

Hi,

I am facing samsung green line issue from past 3 months every month my green line is increasing day by day now it's 4 vertical green line. I have read so many article and you tube video many user have this issue for samsung s20 plus. My phone not dropped any where still samsung asking me to pay for screen.
We are not that much rich to buy new phone every year and repair with huge cost without any fault samsung has to reply why s 20 plus have this issue.
