In multiple applications (StreetView, SkyMap, Compass, New Horizons) my G1's compass does not seem to be responding. Every app that uses the compass seems to hang during a "Loading..." type stage, except for StreetView, which loads but Compass Mode just does not function. A forum search found some people whose compass seems to be srong by some degrees or uncalibrated, but I haven't seen anybody where it just did not respond. Powering off/on (removing battery) doesn't seem to help. Is there any way to test the compass in my G1, or any way to reset it? Thank you!
