I noticed that on my IPhone using Google maps its hard to tell the orientation of the phone in order to determine how to take a turn relative to the phone. When I place the IPhone level, on google maps there is a triangle on the dot representing me that apparently tries to indicate how the phone is oriented. When I rotate the phone around, the triangle is all over the place relative to the phones orientation. Problem is identical on my other favorite app, Maps.me. Apple maps gets around the problem by not showing any indication of the phone orientation, just a round dot. However, there are lots of compass apps that I can download that track the phones orientation perfectly. Also I have some of the astronomy apps that show stars corresponding to the phones orientation perfectly, and they have some functions for calibrating the phone for further accuracy. So why is Google and the other maps programs having problems?
