For what it is worth, we did a little experiment at an Earthcube workshop 3 weeks ago. Poorly controlled experiment in that we didn't force people to calibrate their devices. Even with that disclaimer though, the results were very very sobering. I think we tested 7 or 8 devices; a couple iphones and a bunch of android devices. There was a spread of about 60 degrees in strike measurements with none closer than 5 degrees of the known orientation (using standard analog compass, which was also confirmed with a "geoclino device"--not geoclino software on a phone, the pricey Japanese device). Not sure what this means since the experiment wasn't well controlled, but it definitely fits what Midland Valley has been telling us, which is "know your phone". It seems the sensors are basically useless in some of these devices, whereas others can be quite good. Depends on how lucky you are with your device?
