You should probably try a longer delay like Game and/or keep/increase the size of your circular buffer. The sensors (accelerometer, compass, etc.) on mobile devices are inherently noisy so when I asked about 'low pass filter', I meant do you use more data to decrease the frequency of your app usable updates. Your video was done inside, I would also recommend going to a place with less EM interference such as a park just to check that the behavior is consistent as well as the standard compass reset action (rotate device in figure-8). In the end you may have to apply some heuristics to throw out the 'bad' data to make a smoother experience for the user.
