so I noticed that this thing appears in sunlight as if the brightness is set to automatic mode,like contrast is but here it is the screen contrast, the adaptive brightness has been turned off since the beginning of using the phone, in the settings I did not find anything related to the screen contrast

To understand the problem you need to see the phone in reality but that is not possible so I demonstrate it through the photo app and with the exact settings as I see the screen, in the country where I live the climate is not hot, this thing appears from the sun hitting the sensors next to Face ID
The screenshot looks like the Photos app. Photos is for editing/adjusting photos (screenshots) etc. That’s not a control for your screen.
What iPhone and what iOS version are you using? Does it only happen outside in the sun? Is it hot where you are?
Please follow this path,
iPhone > Settings > Accessibility > Display & Text Size > make sure all settings below are disabled as shown below.
I’m not sure the problem you’re trying to illustrate in the screenshot. It looks normal. Why show a normal picture? If trying to demonstrate the issue, share a screenshot that displays exactly what you are seeing.
Is it hot where you are?
Your is different from contrast.
In really bright light the pupil constricts and lets light in. This makes the screen appear darker in bright light.
I live in Clearwater, FL and the extremely bright light we have here, does this to everyone’s phone, not just iPhones. I see it frequently at the beach. Everyone shading their phone to see the screen.
I have an iPhone 16 Pro Max, and it happens to me in the sun. Whenever I use the phone in direct sunlight, the brightness of the screen becomes as if there's no brightness, even though the brightness is full. It becomes okay when I am no longer in the sun.
I used photo app to demonstrate the problem,I’m on iPhone 13 Pro iOS 18,it’s happening only on sun
on mine only bold text is on,i don’t think that from bold text is problem
Understand,thanks for help
