I've just started testing your demo app and I have hit a serious issue...
I load the demo on two different iPads with the same iOS version and use the "POI from webservice" option. The results on the two devices shoul be more or less the same, but for some reason, they differ wildly (sometimes by 180 degrees and more). I have attached two screenshots from the devices. And the same problem for Android.
