Samsung S21 Green Line Issue After Update

I own a Samsung S21, and out of nowhere, a green line appeared on the screen. My phone has never been dropped or damaged, yet this issue occurred after a software update. Upon researching, I found that many users are experiencing the same problem, which means this is a widespread defect.

Samsung needs to acknowledge and resolve this issue immediately. This is not a user-caused problem but rather a manufacturing or software flaw. A flagship phone at this price should not develop screen defects so easily. I am demanding a free repair or replacement for affected devices. Samsung, take responsibility and provide a solution!
