Display brightness on iPhone is flawed can not see screen in daylight

Despite everything I have seen as a resolution to this issue in post everywhere NOTHING works! When will this be addressed. I can’t be the only one that has set every setting I could on this phone with NO success. The iPhone is completely unusable in any type of sunlight. No matter what you do the screen will auto dim to a level of y usability. I have disabled every setting that auto adjusts the screen brightness. Full brightness still is not bright enough and adjusting goes for worst to even more worse. Rightness will be completely up and as soon as sun hits this screen for even a short Amy of time the screen just goes dark, no matter what you do and I can’t even see it. If it would just stay as it was I would be fine, is there seriously NO SOLITION after all this time? I can’t even go to a Genius Bar and show them cause it ONLY does it in direct sunlight not in store light. And a screen shot doesn’t show the screen darkness. Only way I can think to provide an example is to take a video with another phone to show it doing it but I can’t imagine no one else has seen this issue or Apple isn’t aware of it,
