I just updated to SR Remix KitKat and I noticed that my proximity sensor isn't working now. I can't say for sure that it was the update which caused the problem because a week before this I had the screen glass replaced. Now I know this can be a problem when the screen glass is replaced but I wanted to verify that it wasn't caused by the update before I take the phone apart and try to fix it. I'm posting here to see if anyone else has had this problem with this update or ROM. I tried the hidden menu *#0*# and it wasn't functioning. I also checked with CPU-Z and there was no activity at all from the sensor.
