Android: Compass True Heading - Magnetic declination seem to be added in the opposite direction

    Details

      Description

      For a location like Boston, MA, the magnetic declination should be about -15.
      iPhone handles this correctly by subtracting 15 from the magnetic heading, giving me a true heading that is more accurate than the magnetic heading.
      On the other hand on both the Droid and HTC incredible I tested, the true heading actually ADDS 15 to the magnetic heading, making the true heading about 30 degrees off in the Boston area and making it more inaccurate than the magnetic heading.
