not all android phones have a compass though
I'd rather write code than write docs and do support so I would like to get the process a bit more nailed down* before it has too wide a distribution.

As for which Android phones have magnetic sensors the ultimate way to find out is to get up the keypad, dial *#0*# (yes really!) and click sensors - you should see Accelerometers, Proximity and Magnetic.
An interesting development but the magnetic compass chips in mobile phones are not good enough for a BCRA cave survey Grade 3 let alone Grade 5.The DistoX has three orthogonal high resolution sensors for the magnetic field which is why it can be used for BCRA Grade 5 cave surveys.

I have a number of caves to survey and a Grade 3-ish survey will do fine for me. No-one else will do it so it'll be good just good to get even a rough survey done on them...Regards, Mel.
