Hi i have two oneplus one phones that i purchased new two weeks ago. They are booth running the latest CM12 nightly and google apps. No other mods and booth are showing an issue with proximity sensor during incoming call's.

The issue i am having is that during a incoming call if the proximity sensor is covered the screen goes dark. This is a issue because sometimes the phone is in a bag or under papers and the screen just stays dark when receiving a call. It takes about a second once the sensor isn't covered to turn back on. I have checked and unchecked the"prevent accidental wake up" and there is no difference in behavior either way.

I have also tried the official Cyanoges OS12 and its having the same issue.

Any help would be appreciated.

Thanks
