AC Question

What is the hardware spec of the TRRS Audio port on the Samsung Galaxy Note 5 International (unlocked) version? I need to know which 'ring' of the cable to access the mic input connection on the 3.5mm audio port. Is the TRRS config OMTP or CTIA (AJH)? I have had enough issues with the phone that I don't want to guess or do trial by error.

I am trying to use my Note 5 as an oscilloscope, which I've seen done; and I have used it already as a Geiger counter (using Smart Counter). Anyone who has tried this, it would be really helpful if you can direct me - I cannot believe I haven't been able to find this info on the web after 90 minutes of searching!!
