Android compass question

[Jonathan Lynch]

Hi Jacqueline,

Thank you for this reply. I keep working with this issue, but I still
cannot resolve it. When I put the Android phone down on a table, to be
still, the compass heading from LC jumps up and down by as much as 10
degrees - way too big of a range just to round.

However, the compass app I downloaded on that same device is rock steady.

I really wish it would just work, rather than having to massage the data
from the device.
