Fix Altitude Bug in GeoCoordinateWatcher and Geolocator when using in WP8
Fix Altitude Bug in GeoCoordinateWatcher and Geolocator when using in WP8. On my lumia 520 (WP8) i get jumping values of altitude, even outdor with a strong and good GPS-signal. The altitude jumps from 27m to 200m up and down, 200m is the right value. The values from GPS-accuracy are top. This occurs In both classes on WP8. I always use the DisiredAccuray = high! I have read, that another user have the same problem with WP8-Phone, like HTC. All GPS-App in the store have the same problem with the jumping altitude.
But i found a solution. If you take the Geolocator class an set the DesiredAccuracyInMeters = 1; (Yes set to 1), then the altitude never jumps anymore!!! Please fix the Problem in the WP8-SDK

It's very annoying when using your (windows8) phone as a gps tracker. Previous versions of windows mobile/phone didn't suffer from this problem; those tracked the altitude nicely and correctly.
Hopefully this bug will be fixed in an update...
yes that is realy important problem! i hate altitude jumpings :((((
