Proximity sensor doesn't work properly after screen replacement

After I changed the iPhone 6s LCD the proximity sensor work properly. If I put my thumb over it works, but When I use it in a phone conversation it goes and off all the time. It didn't do this with the broken screen even after I put my old broken glass on again. I understand it's something about the new LCD that's wrong. It's AAA quality.

Is this a good question?

might just not be seated correctly. Give it a clean and check its still fully attached to the ribbon cable


Thanks Eric, it's just so weird. It happens every time I change 6s and never when I change 6.


Depending on the color of the screen you may have to transfer over a filter that is only relevant on white screens. You will find a white diffuser square in the little window where the proximity lens sits.


@techrx that white diffuser square is actually for the ambient light sensor, not the proximity sensor.

More than likely the quality of screen you're using, or possibly the way you're positioning it.

Make sure to glue the proximity bracket in the correct position.

Always make sure to use a little heat when removing the camera proximity, as this then lessens the chance of damaging it.

It is often just an alignment issue when the proximity sensor doesnt work after a screen replacement. You will need to open it up and look closely for the plastic brackets that guide the sensor and camera into place. Sometimes the tiny clear plastic part comes from from the old screen sticking to the sensor. Then if the new screen already has a bracket you would not be able to line it up right.

If you checked and the old bracket didn't stick and move over just press down on the back of the sensor when it is perfectly lined up and feel for the click when you finally get to fall into place. Often this will fix the problem but you should keep some extra proximity sensors and front facing cameras in stock for when this happens.
