Good exercise of exploration ! I read buyer comments on Android that millimeters is not so good either.

A few comments: I don't know much about these sensors, but I don't think there's a need to subtract gravity as the accelerometer will only register if the phone accelerates (i.e. is dropped), in which case you want to know about it. This might be the reason you get a rapid distance increase. If the distance per second linearly increases, there's your culprit. Also you might consider implementing a improved Euler or Verlet numerical integration, the second one stops computation error-caused silly increases in displacement in my experience. You'll need one step of a simple numerical integration to get it started though. Look forward to meeting you soon, Leo Hi,
