    Hello everybody.

    I just flashed the latest cm 12 nightlie and my proximity sensor is working very poorly.
    In calls it struggles to turn off the screen and when it does turn off it doesn't turn back on when moving the phone away from the face.

    I allready tried flashing the 44S modem/radio and it didn't work.

    Going on cm11s the proximity sensor works (using multirom) so it is definetely a software issue.

    Does anybody have a solution or fix i might try?

    Not that I know of. I tried one CM 12 nightly and the proximity sensor didn't work, so I went back to 11S. Remember that this isn't the official build and that it will most likely be fixed when released. It's up to you to keep the ROM

    I have the same issue. Have performed 2 clean installs. It seems that I always need to unlock the screen to take the call. I have disabled the doublecheck of the proximity sensor to no avail, it only stops it from working. May do a more in depth troubleshoot today when I update once more.

    I agree about checking the firmware - I'm running the current CM12 nightly on my device without any proximity sensor wonkiness. I'm no 'expert', but have found that the firmware for at least the modem is (or should be) different for CM12 than CM11S. Good luck!

    Alpha firmware for the modem, which affects the proximity sensor as well.

    My proximity sensor also seems broken on the latest nightly (did a clean install, since some nightlies before it already was broken).

    On cm11s it is still working flawlessly..

    Do you guys also use multirom?

    Alpha modem does not change it..
