My s21 ultra developed pink line 3 weeks back. Now another pink line has appeared. No physical damage. Service centre people saying they won't replace it free of cost unlike s20 series because "not enough people with s21 series has reported this problem". Ridiculous. This was the most expensive phone I ever bought. Won't buy samsung phones in the future
Unfortunately, the replacement cost for the original display will be higher. But that's the only solution.
If you are not worried about the green line issue, I advise you to keep your phone the way it is. And it won't mess up your Galaxy device.
