When Auto Brightness is turned off, the phone screen dims in the sun. In the shade, it does not return to normal over time. To restore the original colors, you need to turn Auto Brightness on and off or reboot the phone.
Happens mostly when the phone's brightness is turned to maximum when there is no Auto Brightness turned on. Black colors seem to turn gray.

Hey, I think I fixed this finally. It’s been frustrating me for years. I do a lot of outdoor work and I live in Orlando, FL. Yes. The Sunshine State. ☀️ 🤦🏻♂️
Turn True Tone off.
Settings > Display & Brightness.
Hey Apple. This shouldn’t behave like this. Looks like you have a bug to fix. The color spectrum of daylight, 6500 K, may be off the end of the scale of where the iPhone is reading the ambient lighting, then causing it to default to the factory default, perhaps? This may be more prevalent in southern or high altitude areas, or especially bright days.
I am literally on Daytona Beach. Been here a hundred times. I can actually read my screen without straining.
Here’s what’s happening specially:
Auto Brightness Off
Brightness at 100%
True Tone On
In bright daylight, the screen dims. If anything, we should get the opposite. A little boost, like 120%.
Turn True Tone Off: The screen stays bright.
Hit me up if I can help more.
thx mods 🙄
you removed the quote portion of my message so now it's meaningless but really incredible work
