For the most part, I have changed my tune a bit on this because I do believe that none of us should have to accept this as it just being “it is what it is!” There is a clear difference in tone temperature between older iPhones (even OLED screens) and the iPhone 12 lineup, seemingly more so with the Pros. Even with auto brightness on, there should be no change in tone without True Tone being on. Furthermore, if one has different apple products, say, an iPad, MacBook, etc, switching from one screen to another may also bother the user.
I do have a tough time believing that this is all from hardware issues. That so many would be defective. I’m hoping it’s something within the software that can recalibrate and fix the problem. Maybe even an issue with the ambient sensor that controls True Tone is still activated despite True Tone being off.
I don’t know. But I’m kind of stuck now for I’m passed my return date and I traded in my iPhone 7 Plus. I also don’t know if I want to fight with Apple right now to get a new replacement, just to have the same thing occur. Because I will not settle for a refurb or repair one month into owning this phone. Disappointed Apple!
