True Tone Option Disabled on iPhone 8 Plus Running iOS 12

Hello! I'm pretty sure many of you are familiar with the bug that disables the ambient light sensor and true tone display on the 8+ with an aftermarket screen. I'd like to get some feedback from users using iOS 12 on an iPhone 8 and 8 Plus w/ aftermarket display. Does yours work perfectly? Here's what happened with mine

-Running iOS 11.4.1. Installed a new screen and True Tone was working perfect but the ALS was disabled.

-Here's the twist. Updated today to iOS 12 beta 3 now True Tone is disabled (missing) and now the ambient light sensor works but is kinda slow imo.

Can anyone share their experience? Hopefully Apple with enable BOTH True Tone and the ALS

P.S. I ordered a used genuine original screen cause I'll be keeping the phone (not selling got it for only $280!) hopefully everything would work with it and will update this post.

Answer this question I have this problem too

Is this a good question?

You probably got a aftermarket screen, or the screen has been replaced with an original (oem or refurbished) without the use of the ALS programmer.

it appears that on iOS12 its not enough just to copy screen data described in REWA video? Just replaced screen with another original screen (from another device), copied data and true tone disappeared.

apple continues to behave awful toward repair community

The screen is paired with the logic board.

To get both working fine the display data from the chip on the display cable needs to be copied from the original screen that came with the phone to the replacement screen regardless of whether it was original or not.

It requires a flashing fixture that copies the data from one chip to another. REWA technology has released a product and video demonstrating this on YouTube:

I had my display replaced BY APPLE twice in the same day. First due to random touches. Then the replacement got a green line after 2 hours so i went back and they replaced it again. Being going fine until iOS 12.1 and now True Tone is gone on my iPhone X. Again all work on my phone was done at the Apple Store.

Ok so my iPhone 8 Plus screen (the screen that came on my iPhone straight out of the box) started to do the whole random touch craziness… it got so bad that it actually caused my phone to disable itself and I had to wipe my entire phone. A normal person would probably always remember what ,both, the unlock code to get into the their phone AND the password to the iCloud used when setting g up the iPhone right??! Well, NOT ME..

I just became way to comfortable with the Touch ID feature because the only time I had to ever use the actual password for my iCloud was when I set it up initially, and after that, I would always just use the Touch ID to retrieve the stored password I had entered following the initial entry. The same goes for the unlock code that I initially set up, so that no one, other than myself, would be able to gain access to my phone. I entered it once, and that passcode was never thought of again since I immediately entered it into my phone’s stored passwords section.

Now, I know you must be thinking, “Didn’t you have to enter in, at the very least, the unlock code after the phone ‘s battery life was used up”? That’s just it though, I never let my phone’s battery drop below 6%. Thinking back, I really am regretting not glancing at the password(s) a lot more than what I had done.

I had kept a perfect personal record of not having to enter either password for the last year and a half. Then, the screen started going crazy and the next thing I knew, my phone was disabled and the only way to fix it was to wipe everything!!! Yep, passwords and all were gone. I was screwed.

Not even a full 24 hours after my phone disabled itself, I dropped it face down and shattered the entire screen. So I went and had the screen replaced. Everything works exactly like it should. Except for the True Tone. I am running iOS 12.3.2 and I can’t find it anywhere.

So, for those who are waiting and hoping the next software update to fix the issue, I believe you will be waiting a while… I mean A WHILE!!
