Screen temperature

[Guyinbox]

Does anyone notice the screen color temperature being way too warm? On the lock screen, the colors look normal but when unlocked the screen shifts to a yellowish tone. If i put the display calibration to vivid, it pretty much looks orange. I don't know if there's some sort of hidden scene optimizer at work out what, but it's really annoying.

Edit: It's definitely some kind of bug being caused by turning on the blue light filter. For some reason it's being applied after it's turned off. A factory reset fixed the problem until I turned this back on at night.

The reason it reverted after a hard reset sounds very much like a setting. I'm not fond of hard resets except for trojans, or old loads with junk data that can't be readily deleted.
Finding the setting or apk causing the issue is always better to do in the long run.
Play with it... like you would a hot bad gf.

Does it do it in Safe Mode? If not a 3rd party apk.
A package blocker is useful for ferreting out the source many times.

Never used that OS but go into Developer Options and see what's available for global color management.
Try setting it to R/Blu/Grn if it's an option.

Last resort use the apk Color Calibrator to dial it via overlay.
Color management on Androids suck. On my Note 10+ I had to use the above app to dial it in unfortunately by eye.
These trash OS's lack screen color calibration/management like you have on a Windows based system.
I have a top shelf OLED and no good software to control it's color management. Masterpiece.
Extremely irritating; I feel your pain, apparently google does not...

So I figured it out via a suggestion in a galaxy s10 support forum. I had to reinstall Google play books and go into the settings while reading a book and turn off night light. I didn't think this would work initially since I had already uninstalled it. It's really strange that this applied system wide, but that was the cause.

Yeah I remember that causing a issue , glad you found the problem
