@ren_snappyI am so sorry I cannot understand what you mean.
I do not understand how you can solder temporarily.
Another point I do not think the audio board is working on the mic with Android, I never tried it and used it only for listening.
I think the forum is the right place to ask your question and maybe someone will help you better.
You could also joint the 96Boards OpenHours on on thursday and ask your question
You could then show us what you mean by “soldering temporarly”…
