Screen Shutting off during calls

I replaced the digitizer assembly last week due to a broken screen. From then on out the screen shuts off while making or receiving calls. Initial troubleshooting lead me to believe this is a proximity sensor issue. I checked to make sure that I transferred the foam sticky square over to the new digitizer and I did. There does not look to be any debris between the glass and the sensor either. What am I missing?

Hey William!

If the sensor is not damaged, and foam insert is there and correctly aligned, then chances are it is being cause by the screen replacement. When they manufacture these, they sometimes make the hole over the sensor too thick, or too dark, which blocks the light and activates the proximity sensor.

If you can, I would put your old screen on and see if the sensor works. That way we can know for sure if the problem is the replacement screen

I already threw away the old screen :(

Is there a safe way to clean the sensor? Maybe there is something in there.
