After replacing the screen with the iFixit spare, the "auto-brightness" option is gone (ios 11) from accesibility:

I admit that support was good, they finally replied and tried to be helpful.
The problem I had, and still have is with the BAD QUALITY of the parts.
I just finished sending my latest email to support, telling them how, for the THIRD TIME, the replacement screen they sent is again defective...
To recap, the situation was the following:
1. I purchased a replacement screen for an iPhone 6s on iFixit, even though the price was higher than on other places, but expecting to get a high quality part.
The screen (the first one) they sent had many issues: fuzzy image (glue problem?), low backlight, issues with auto-brightness.
2. I sent back the screen and got a SECOND replacement. This time, the image was sharp and the backlight as bright as the original apple screen, BUT it had other issues: a blue spot on middle of the screen (again, some glue issue?), the backlight on the top and bottom had a noticeable bleeding specially on dark images, also the left half of the top backlight stopped working from time to time, the 3D Touch was not working well across the whole screen (irregular pressure detection, sometimes even didn't work at all)
3. I sent back the second screen and got back a THRIRD one. I specifically asked the support team to TEST IT thoroughly beforehand. Still, this new display has again some issues: again the backlight on the top and bottom had a noticeable bleeding or blobbing, irregular and sometimes non-working 3D touch, and once again, like the first screen they sent, the colour is blue-ish (again something to do with bad glue of the screen?).
On all THREE displays, the "auto brightness" feature on iOS11 is missing. The "description text" is right there, in Settings>General>Accessibility>Display Accommodations, but the option switch itself is missing. When I install an original apple screen, the feature comes back.
I already gave it a try with the iFixit screens, but obviously they all seem to have quality issues, and most of the really big issues.
It seems that iFixit has a warehouse full of bad screens, and they should do something about it instead of keep shipping them to their customers.
They definitely lost me as one, but they can still keep other customers if they act on this problem fast.
Once again, I have no complaints whatsoever regarding support: they have a good attitude, and they are willing to help. But, they have to improve the quality control over the products they sell.
