Yellowish screen after update one UI 6.0

[A1ex6arcia]

Is anyone having the same problem after the last update?

I've tried all sort of changes in the settings including turning off Eye comfort shield, all visibility enhancement under Accessibility, and everything I found online but nothing worked.

Somebody suggested resetting all settings, which I tried but it didn't work. 

The last option that I didn't want to do, but I ended trying was a Factory Reset, and the problem is still there. Nothing works, and it's so annoying.

I know it is not a hardware problem, because the screen looks perfectly fine most part of the day but it is activated automatically around 5:30 PM and stays all night until around 7 AM. It is a software issue.

The issue is android core function "Night light" which is equivalent to Samsungs "Eye comfort shield" with that difference you can't access"Night light" without some tool (or adb command).

You have to download Nova launcher to change it, then you can uninstall it. On the end of OP is very detailed step by step video.

Profit.

This solution worked. I read these instructions before and tried it, but they didn't work a few days ago. Today I followed the YouTube video that your link referenced and with the video was clear, I believe that I did something wrong when just following the steps.

Here is the link, I hope this helps for everyone.

I'll follow up again in case this problem returns.

Thank you so much!

Just as an additional comment, if you changed Nova Launcher as your default Home screen and you fixed the issue, the way to come back to your previous home screen as default is through Settings > Apps > Nova7 > Defaults/Home screen and change it back to One UI Home.

There might be other ways to do it but this is what worked for me

A52 5G updated to One UI 6 yesterday and suddenly yellow tint from dusk to dawn. I cannot turn off the blue light reduction setting. The only way I could defeat it was to turn off network access and adjust the time to something during the daylight hours. Immediately the yellow tint disappeared. So clearly it's something having to do with the eye comfort shield no longer being responsive to the on/off switch in the Samsung settings. Clearly a Samsung One UI 6 bug, and I hope they fix it soon.

BTW, I don't understand what people are talking about with regard to Nova. There is something called "night mode" in the Nova settings, but that switches a dark theme on or off, it does not have anything to do with a blue light filter and would not cause a yellow tint either way. Keep in mind that mention of the supposed solution using Nova is at least 5 years old.

The Nova thing worked for me, even if it's an old post it was the way I fixed the issue

That's great. I'm glad it worked for you. It had absolutely no effect for me. The only thing that works is to trick the phone into thinking that it's daytime, and the yellow tint disappears immediately. Apparently there are a lot of people complaining about this so I hope Samsung fixes the bug ASAP.

Samsung developer technical support said a patch was going to be made available within 5 days for the affected phones. We'll see...

The Nova Launcher fix worked on my A52 5G.  It was a little tricky getting the launcher set as default as it required steps not shown in the video.  But the rest went as described.
