Just compensate the error that is introduced by not actually pointing the

need to change any algorithm, just compensate for the dude, you're holding
it wrong

I think you should learn something about the way direction (and
orientation) is specified in computer programming.

Pedro,
If I understand you correctly, you are having difficulties with the
device's orientation.
The bearing angle seems to be computed in the horizontal plane. If you
wish to adjust for the device's orientation, you need to concatenate it
with the bearing angle.
Google for quaternions.
