I have been seeing the screen getting discolored very frequently with a Greenish/yellow unpleasant color layer on phone since the recent Software upgrade has happened in the month of March 2020.

So far I have spent around 20hrs in troubleshooting the issue. No luck with the fix.

Trouble shooting steps below

Restarted the phone in Safe mode. Did not resolve the issue Cleaned up the Cache partition. Did not resolve the issue Phone does not get hot The discoloration happens most of the times when I unlock the phone and it remains like that until I lock the phone and wait for about 15 seconds and the try unlocking it. Some times it hit and miss. I did a factory reset today. After the reset was complete, in the initial screen where the phone asks to select the language the same discoloring of screen happened again. So this proves that there is an issue in the underlying software that was modified with the recent upgrade that was pushed by Samsung. The lens function is turned off in visibility settings Blue light filter is turned off

It is really frustrating to use the phone with this issue . The phone just looks awful with this issue and it is not at all a pleasant user experience.

I have seen many other people complain about this issue on other forums. Posting it in samsung official community page to take this issue to Samsung's attention. Hope they will fix this ASAP.

4/9/2020: Some of Samsung's product technical support team members in this thread have replied asking me to pay a visit to service center. In the middle of COVID19 Crisis I do not want to risk my life for a phone. So I have as requested them to let me know if they have other means of trouble shooting of remotely diagnosing this issue. So far did not see any futher response

4/9/2020 Edit: Uploaded 3 files to show the comparision with another phone. The below images pretty much explain the issue. I have included some description of the issue on the image as well.

July 5 2020_ Updated May and july updates in my Note 9 phone . No luck so far . Thousands of people are reporting this issue with other Samsung phones , like S10 and S20. Looks like Samsung is releasing fix for t hff d phones that are in warranty and leaving every other customer is being ignored. After waiting for about 4 months and not seeing any responsible statement from samsung , I have decided that I would say bye to Samsung for good and will return back to Apple products. Apple shows commitment. Their stores are lot of convinient to discuss these issues with a representative face to face and get things resolved .
