Accuracy of sensors is not a property of android, but of used hardware. Sensors used in HTC Hero sell for about $3 wholesale - I would not await much precision there. And compass, being magnetic, is sensitive to ambient magnetic fields ( resulting from electric installations around you) - so relative readings may be OK, but not absolute -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
