Chosen Solution

My screen shatered on my Nexus 5X. Took it to a repair store, replaced screen/digitizer and now when I make a call (push the green button) the screen goes black, same when I accept a call. Only way to fix it is to reboot if no one answers.

Hi, the issue is with the gasket that the sensor fits in. The repair shop has most likely left it on the old LCD. Remove the foam bit that the sensor sits in and fit it to the new LCD..

@thetechguysmcr That totally fixed it for me! I was afraid that I had broken the actual sensor while replacing my screen, thanks for the tip.

The only thing I have figured out is to change settings so that the Power Button can end a call. I have taken the phone apart and it does not seem that the proximity sensor (or light sensor) can be removed/fixed. It is soldered to the motherboard. http://www.androidauthority.com/nexus-5x
