It becomes a hot topic about the Problem of iPhone 8/8 Plus/X Ambient Light Sensor Failed after screen replacement, Future Supplier has also been trying to find a solution.
After repeatedly research and testing, we have solved this problem successfully on iOS 11.4 version with a newly developed PROGRAMMER. The screen data can be cloned to another screen and ambient light sensor function back to normal. Of course, the face ID function still works normally. We guess that Apple Inc. uses encryption technology to make the phone lose its ambient light sensor once the screen or other parts were replaced.
At the same time, we found that the ambient light sensor function works properly on the iOS 12.0 Beta version, but not sure whether it will still work properly after iOS 12.0 official version released.
Pay attention: The premise is that your iPhone X is original and other functions are intact except the screen need to replace. After screen replacement by using our ALS Programmer Box, the phone can adjust brightness automatically.
