Galaxy S21 FE Green line issue after March 2024 Security Update

[Afzaltec]

It was March 26 11 55 p.m and I was using my S21 FE exynos variant as usual, scrolling through linked in posts. Suddenly, a mild (very tiny width) green line started appearing in the left side of the display and it vanished within seconds.

I got really scared and stopped using my phone. After few mins, I tried to use my phone normally but this time the green line started appearing and disappearing multiple times. 

After getting really scared, I was messaging my friend regarding my issue and the grren line became a thick white line and it became permamant. 

Now I'd like to add that I've never dropped my phone. My phone has a very high quality tempered glass as well as a case. This is my first time encountering this issue and I believe that it is caused by the recent March 2024 Security update. 

Can anyone suggest a solution to resolve this issue? 

I'd request Samsung India to offer a free display replacement since their caused this disaster which didn't let me sleep last night. 

UPDATE: Samsung has resolved my issue; Know more, https://r2.community.samsung.com/t5/Galaxy-S/UPDATE-Samsung-replaced-my-S21-FE-Display/td-p/15971269...
