Is there a way to fix the missing “auto-brightness” option?

Is there anyway to bring back the missing “auto-brightness” option after replacing an iPhone 7 Plus screen?

I replaced my screen, with one from iFixit, and and while the screen, Touch ID, Camera etc work fine, I seem to now be missing the option to enable auto-brightness. This makes the phone very hard to adapt between indoor and outdoor lighting conditions without manually having to change it all day long. And leaving it at a higher brightness results in horrible battery life.

Is it missing the option in settings or is it just not working?

The option is completely missing. It was there before the replacement as it’s something I periodically check but now it’s not there. It used to be the last option just below “Reduce White Point” in accessibilities but now it’s totally gone. I’ve heard this can happen to the True Tone option on newer ones unless you transfer the screen calibration data using an EEPROM programmer but I was not expecting “auto-brightness” to have the same issues. Any ideas?

In my case, the screen/front camera combo I purchased from Amazon was missing the ambient light sensor. The auto-brightness option disappeared for me as well after the phone updated from iOS 14.01 to 14.1. I then replaced it with a FX5 in-cell screen from Injured Gadgets along with their front camera/sensor cable and after a DFU reset, the auto-brightness option came back and is working perfectly. My guess is that the iFixit unit doesn’t come with (or working) ambient light sensor. You can try to do a DFU recovery and see if the option comes back.

Without Apple’s Official tools, you have to keep the original screen and ALS flex cable, get a screen/ALS programmer, copy data from the original screen/ALS flex and write into new ones.

This does not make the ALS color/brightness sensing accurate, because the calibration data is from another unit that has different physical properties, but it does trick the phone into bringing back the options.

I think the DFU restore suggestion fixed mine. I only did the DFU restore because of a different issue but apparently it fixed my Auto-Brightness at the same time. Thanks!!!
