Ambient light sensor is not working (full display assembly)

I have ordered a complete, assembled display replacement (display, touch, earpiece/mic/etc. already installed, only needed to put it touchID home button), and the ambient light sensor won't work.

As some have mentioned, for the auto-brightness setting, they get the text in the accessibiliy/display accomodation settings, but not the actual on/off switch, hinting at a "missing" sensor (or what the software deems as not working sensor). The rest (proximity sensor, front facing camera, earpiece) do work just fine though.

Is it possible that the assembled display unit came broken, or is there something else I missed to do/check/change?

Thanks!

It may have to do with the screen or the sensors. If you have checked if the cables are properly connected, and it works fine with another screen on it. You most likely received a defect assembled display unit.

Thanks Rick for your response;

Just a short update: received a replacement display assembly from ifixit - same problem. Everything works but the ambient light sensor (well, it might work but the preference switch for auto-brightness is still off). Since I am using this phone 'productively', I didn't want to play around too much with it and test things out.. I was hoping someone else had the same issue and knew how to 'easily' fix it..

All I found on the web was that it seems that only the original cable works in some cases - which for now I refuse to believe, otherwise ifixit would have had many more returns?

You can take the front camera assembly from the old display and transfer it to the new one.

It's not rare that you get defective parts on pre-assembled screens which have the front camera, earpiece and etc on them.

Thanks Ben - my original thought was that I didn't want to do this, as this would mean a high risk of breaking more than I would repair (hence the full assembly display unit and not only the glass replacement).. Still not giving up on some magic fix in the software, and not having to open the phone again ;-)

Sometimes the software just not recognise the new hardware. Put your phone to DFU mode, reset and update the software through iTunes. If the auto brightness not damaged it will solve your problem.
