Green Screen Discoloration on S9+

[patagoaniao]

I'm having this specific problem where my screen would go green (as if they the pixels are dead) when I

1. Wake the screen and attempt to unlock the phone 

2. Calling on Whatsapp or using general line

The problem does not persist at all when I am in between apps and running tasks. 

Any solution? I have factory resetted, tried safe mode and tried flashing (failed as I waited for 9 hours). Nothing worked. Some forums say it's a software and not a hardware issue (indeed cause there is no permanent discolouration. Just in the lock screen and some apps)

This is the issue - https://youtu.be/m0-npdV-U2c - apparently quite a lot of people (from comments section) are facing this issue at the same point of time.

bad luck. mine was affected too. nothing much can be done. samsung quoted change LED. and it was RM 800+. phone is in my drawer now. till now Samsung is keeping quiet without acknowledging this quality issue.

Happens to my note10+ too this few days. I've suspect due to the Samsung software update too.
Sometime it able back to normal color when adjust the brightness.
I believed the Samsung software just to ruin the old phone.
