Hi we really need an update for the compass and sensors as navigation and gps are way way off showing north as south-west and so on ...I have tried the colibration for compass and dose not matter how many figure 8s I do with the phone it will not calibrate and can't use a Bluetooth tracking tag because the compass dose not read correctly and my GPS is all over the map when I'm sitting stationary in my bedroom .....and no it has nothing to do with electronics around me because I don't even own a tv...the only electrical device in my room is this phone ....so please update the sensors so they can actually be used as intended
