Re: Random N / S direction change Onstep Android app.

It doesn't really depend on how close you are to Polaris. It has everything to do with true North and the direction you pressed on the controller.

Here is how I explain the behavior.

The basic rule is that it always wants to go North when you press the N button.

OnStep starts with the telescope at NCP (North Celestial pole). Pressing the N button will cause the telescope to head South. This is the only direction it can go since it is already at North. Release the button and press North again. It will reverse direction because now it can and will go North. Keep holding the button passing the polar axis (scope aligned with mount) and it  will continue, but now it is actually going South. Let go of the button and press North again. It will reverse direction again,  heading North.

This can take awhile to wrap your head around. Play with it and it will become obvious.  Of course, all of this is reversed for our friends below  the equator.
