wife broke screen. Can't get proximity sensor to work after replacement

My wife broke her new droid 4.
I ordered a replacement screen from repairs universe.
I followed instructions. put the phone back together.
Everything seems to work fine except:
When you make a call to or from the phone, the screen instantly goes black. If you are calling from the droid, the listener can not hear. If you are calling to the droid, the reverse happens. So I have a hunch that the proximity sensor isn't working right.
Speaker phone works perfectly. Plug in a set of headphones and make a call, and that works great too.
I took the phone all the way apart again, and couldn't find anything that I covered up with the double sided tape.
I looked around and couldn't find where the proximity sensor is to see if I had messed it up.
Any help would be appreciated.
It's possible you broke the cable that connects to the proximity sensor.
Do you know if the light and prox sensors are on the chip that's connected to the glass or on the motherboard on the droid 4?
I can't seem to find that answer anywhere

[Q] Vibration damage?

Is the HTC one susceptible to damage from extreme vibration, specifically when the camera is on?
I know the optical image stabilization involves moving parts.
Could intense vibrations from something like a handlebar mount damage any of the components in the device?
Im also curious if magnetic fields can cause any damage. I've played with the idea of building a custom magnetic mounting case to replace velcro strips.

the accelerometer, gyroscope, proximity sensor, ambient light, compass & etc. .they stop working and its very nerving thing

Honor play speaker distortion

I just got the screen replaced on my Honor Play and now the speaker seems to be distorting when I'm playing audio. I can also see a very small amount of light peeking through where the screen is affixed to the body. I have a 30 day warranty on the screen replacement. I'm worried that they'll refuse to do any further repairs for me. Has anyone else experienced anything like this and should it be an easy fix for them to do?
Thanks.
