A lot of people are having this issue. Initially I though maybe this is caused by some app I might have installed but later after debugging I understood it has something to do with recent monthly OS security updates (Based on personal experience and debugging. I don't have any concrete proof but that circumstantial evidence suggest OS issue).
I don't remember when I started getting this issue but it was surely in the Month of August that I first realized the problem.
So far I have tried below steps but non getting any permanent fix.
1. Restarted the Phone couple of times with no luck.
2. Uninstalled the apps that I had installed in recent time.
3. Restarted the phone in safe mode to check any non preinstalled app might be causing the issue. Still no luck .
Getting Green Tint issue in Safe Mode.
Note: Resetting the phone is a very painful step to do. Losing years of Data and many more. I highly doubt it will solve the problem but if you have the patience to do it and if the problem solves, do update.
As of now I have one work Around that I am using to reduce my frustration.
--------------------------------------------------------------
Activate "Always On Display" from settings.
Now unlock your phone. The green effect will vanish for the current logged in session.
Always unlock once you have received "Display Watch" either automatically or by double tap (Based on the selection of "Always On Display").
---------------------------------------------------------------
Many of you might have noticed that when we receive any notification and "Edge Lighting" effect is on, while unlocking during this the Phone display opens normally.
During the initial days of getting the issue I though maybe my phone's display is broke and I might have to change my phone. I even started browsing s20 n few others. I just hope that this issue is fixed by Samsung in the next Software release.
