I never thought I would have to face such an experience. Got a green line on my S21 fe right in the middle of the screen after 6.1 update. The line is very thin and exactly in the middle. A bit confused whether it's a hardware issue or a software issue. 🇧🇩
Another victim. I am also affected with the green line. Not the 6.1 update but the previous Security patch update (April). So I didn't update the OS this time, afraid it will cause more green lines. They gave free screen replacement in India for other models but not for mine(s22).
