[Galaxy Camera Q&A, Help & Troubleshooting] luscoma:
And it continues:

Here are the camera parameters you can set in Camera.Parameters (determined via dumpstrings and a regex to look for anything lowercase with '-'. Interestingly you can't poke the factory ones UNLESS factory-testno is > 0. So I did a quick experiment setting factory-testno to 1 and then poked factory-af-pos. I had hoped that that would let me control the motor, unfortunately it seemed like it just toggled the AF mode from af, macro, infinity or something similar :/ Still searching for a way if I can find out.
