Hi there!  I need the pinout of the Galaxy S3 headset because even though I have other TRRS headsets, none of them seems to fully work with the S3.  All the headsets that I have tried work only as headphones, but the headset microphone does not seem to be detected by the phone.  I'm pretty sure it must be something related to the resistances/location of the GND and MIC signals, which are not standard across phones.
