Screen being yellow?!

Do you have True Tone and/or Night Shift feature(s) enabled? Both can be found in Settings ➔ Display & Brightness : Here you can check what is enabled. Enabling Night Shift will definitely cast a Yellow tint on the iPhone's screen.

Same issue here. Already exchanged once, and wondering if it's a systemic issue :(

Even when you exchanged it for another one? Did you go to an Apple Store?

There's definitely something wrong with these screens. It is super yellow with TrueTone ON. My screen actually has a green tint when TrueTone and Night Shift are OFF. CS didn't help much either. Super annoyed
