I'm running latest cm11 nightly (27Jan) on my Samsung Galaxy S4 I9505 international version (jfltexx), but noticed the proximity sensor is broken since quite a few nightlies ago.

When I take a call, the screen goes off, but then it never comes back on again until I press the power button, or after a long delay. Checking with cpu-z, the sensor initially detects 0cm when u touch the proximity sensor, but upon lifting finger, it never gives a higher value (usually limit at 8cm). I can't post to the cm11 development thread to get help on this (maybe coz I've not chalked up enough post counts). Any idea on this will be much appreciated, thks.

maybe it is dirty? from the inside of glass, i had this, posted how to disassemble S4 and how to clean the sensor and glass from the inside. from 43-51 (avarage sensor value) i got 12-16 and the trigger is 46 (going back from close to far).
I had the same symptoms as you, screen black untli i pressed something.
