This morning I have faced the same problem of a white line suddenly appearing on the S21FE screen. I wrote to Support at Samsung Member. I was advised to reset the cell. I have done the factory reset today. But the white line is still there. Samsung must replace the defective screen FOC immediately. I am feeling cheated for my handset getting this problem. We buy Samsung products with the expectation of trouble free performances.
Very bad experience with S21FE. White line issue is occurred in my S21FE Phone. I visited samsung care they told me all samsung S series phone are repared by free of cost except s21Fe for same issues.
