I can't comment on the G1 specifically, but magnetic compasses are frequently scarily inaccurate if there's any metal around --- try it in different locations (but pointing in the same direction!) to see if the deflection varies from place to place. (Once scuba diving I found myself swimming in almost literal circles because I was a few metres away from an old magnetised torpedo, that was causing a complete 180° deflection. Even unmagnetised metal has a severe effect. Of course, if you're *not* standing on top of a lump of iron, +/- 46° does seem like a lot.) -- David Given [EMAIL PROTECTED] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
