Hi everyone! I think I have the solution. It seems as though some iPhone X models came preset with the “reduce white point” function checked.
Settings>General>Accessibility>Display Accommodations>Reduce White Point & Auto Brightness
Turn off both for max brightness.
Also just to share a story/vent, I noticed my X was 50% less bright than my 6 so I did a hard reset and messed with the settings and couldn’t get it to improve.
I went back to the Apple store and talked to an employee who was super dismissive of my concern and assured me that’s how Apple intended the screen to look. I told him that I thought he was wrong and he cut me off and asked if I just wanted to return or exchange it.
Since I had just gone through the entire restore process I did not want to so he replied “well that’s how they made the phone and if you don’t want a new one then I don’t know what do for you.” I asked “Can I please just have a second opinion?” He replied “my opinion is that the screen is working perfect.” I said “I know that’s your opinion, that’s why I would like a different one.”
Finally, after all that hostility () the employee called over a coworker and asked him to give me a second opinion. The guy took out his X and compared the two, looked at my settings and instantly noted something was wrong. It actually took about 3 guys huddled together to get to the issue. Hah!
