when call is in progress screen goes blank as expected, doesn't unblank

[jbreazeale]

I have a call in progress, the screen goes blank when the phone is at my ear as expected. When I take the phone from my ear to look at it the screen does not reappear. The phone was recently repaired, so perhaps something wasn't reconnected. Otherwise, is there a setting that could be unset that needs to be reset? I have had setting change without my explicitly making changes, so nothing surprises me! Thank you for any assistance you may be able to provide. If it matters I'm on Verizon, kernel version 3.4.0.

The usual cause is a screen protector which is interfering with the phone's proximity sensor.
