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.

I am facing the same issue. Samsung service centre folks told need to pay for replacement of the display and asked me to check with customer care. When I reached out to customer care they informed free replacement is for Samsung s21 , s21 plus, s22 ultra and not applicable for s21 fe.

Ask the customer care to forward the issue to higher authority. They will provide a solution.

I was shocked to see 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 right side of the display and it vanished within seconds.

I am from Chennai, India and I have the same issue. It happened last week. However, in the service centre they are saying they do not have the approval for screen replacement for s21 fe yet!

I got my first green line after last Oct update and now I have 14 green line.

I am struggling with this line and samsung is reluctant to replace it.

Samsung has been behaving the worst by not offering the FE variant a free replacement, already it's exynos and struggling with heating issues and now the line...too much frustrated. I should  have gone to consumer court long back. Atleast something worthy things would happen.

14 lines? Man, that's crazy! Did u approach higher officials through customer care?
