iPhone 4 proximity sensor fix

The iPhone 4 proximity sensor is suppose to detect when your face is against the glass and turn off the screen, so that you don’t inadvertently press buttons or accidentally mute your caller. Problem is sometimes the screen still lets in some light confusing the sensor into thinking it’s not being covered. What we’ve noticed is this problem is inconsistent. Some sensors seem to be more sensitive than others. Here’s a pretty simple fix we’ve been using with high success to alleviate the problem.
