S21 Fe green line issue

[Sal0007]

On April 25, while using my Samsung S21 FE phone, I noticed a thin green line briefly appear on the left side of the screen while scrolling through Instagram. Initially, it vanished quickly, but later it reappeared and stayed permanently. 

Despite never dropping my phone and having it protected by a high-quality tempered glass and case, the issue persisted. I contacted Samsung support, but their troubleshooting steps didn't resolve the problem. I suspect it might be related to a recent security update, 

as this is the first time I've encountered such an issue since I started using Samsung devices in 2015. So, I'm hoping Samsung India can offer a free display replacement since the problem doesn't seem to be caused by any mishandling on my part. Any advice or solutions would be appreciated.
