Default [Q] Nexus 4 with a defective proximity sensor

Ok, so I recently just had my phone repaired, cracked screen, etc. I just NOW realised my proximity sensor is defective.

I go to make a call, screen goes black, pressing the power button allows it to come back on for like, 1 second.
I just now set it to hang up the phone using the power button.

I am NOT using a case or screen protector, and I used an app to test the sensor, and it's not moving whatsoever.

Is there a way to disable it so it does not shut my screen off?

Edit: I finally figured out how to configure the "Proximity OffScreen Lite" app to get it to work.
