My oled is failing and turning yellow

[tgg1]

I had this on my old s10 where it got a yellow tint and then a bit later it started to go full yellow 

I was able to get rid of it but like my old phone it'll probably come back so what should I do

@tgg1: Please can you swipe up from your Home screen and head to Settings > Display > Eye comfort shield, and make sure that this feature is toggled off? Also, tap on Screen mode, select 'Vivid', then adjust the White balance so the white circle sits in the centre of the bar. I'd also recommend tapping on 'Advanced settings' and making sure that the Red, Green and Blue sliders are all the way to the right. 

Let me know if this helps.
