No it acts just the same. I went through every one of her apps. She has a total of 31 apps. I installed 5 of those yesterday and today. Of the 31 16 work like they are supposed to. The other 16 always open up in black and white.
No reading mode, no color conversion, no dark mode. I have booted the phone in safe mode but it does the same thing. I have found out that if I install a new app it opens in color
She has an Zmax 11. No power saving modes. I matched all of her settings to mine with no results. It is every app. I first noticed it on photos. All of them are in black and white. If you go into chrome it's all black and white. I'm totally at my wits end.
