POSSIBLE SOLUTION:
So here’s my story. I received the 256 iPhone 11 Pro Max yesterday. Before opening, I went to the Apple store in woodcliff lake, nj to see how I’d like it in case I wanted to return it.
Most iPhone 11 pro max phones had some yellowing. I looked closely at 5 of them. I compared them to each other and the iPhone 11 and iPhone 11 pro (2 of each). I also, of course, compared them to my XS Max.
3 of the 5 iPhone 11 pro Max phones were excellent. Bright and white. The other two horrible.
I called a customer service guy over, Lucas, and showed him the difference. He had no idea what was up.
Here’s what might help everybody. I went home, opened mine, set it up - and it was HORRIBLE. Photos yellow, internet pages yellow, emails yellow...
Obviously a return. Until I did this...
Went to Accessabilites. Toggled Auto Brightness off and back on 4-5 times. Left it OFF.
Then, plugged phone in to charge to get battery to 100%. As it was charging, I went to TRU TONE and turned it OFF. Put phone down and walked away for around 20 minutes.
Came back to phone and turned AUTO BRIGHTNESS back ON.
Turned True Tone back on.
Left phone to get to 100% charge.
Unplugged phone, and BAM. Screen is beautiful. Now even whiter than my iPhone XS Max.
This is amazing. I’m now keeping the phone.
To be clear - I have been comparing to my old phone all night. It started off yellow and dingy. It is now perfect white wear it should be.
I don’t know how it happened. But I’m glad it did.
