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!

Is this a good question?
