Works Amazing for iOS, but seeing issue in Android when tilting Up & Down

[ChiaHuaLu]

I was trying to use CompassReactNative in my RN app.

On iOS, it works beautifully. As I turn side to side, the values aren't Rubberbanding like I see with ReactNativeSensorFusion on Android (I couldn't get its compass to work sensibly with iOS). And if I tilt the iOS device up and down, the compass reading only moves a little, as I expect.

However, if I tilt the Android device up and down, the value flips if I tilt it past the horizon, as if I turned around ~180°
