Both microphones (Speakerphone mic and normal mic) don't work.

The speakerphone stopped working months ago, nobody could hear me, I even tried to restart my A12.

And this morning after a hot steamy shower (and my phone sitting by the shower) the non-speakerphone microphone stopped working. I assume humidity of the steam from the shower ruined the microphones on my A12. Is there any way I can fix this? I don't mind opening up my phone and replacing something if I have to, I love this phone its my prized possession better than iPhone imo.

Somebody help, I don't want to get a new phone if I can help it.

@badass_sunset easiest one to replace will be the main mic. It is on your sub_board (charging board). Since iFixit does not yet have a specific guide for that, use this video The charging board is readily available at many online places and not to expensive.

The sub mic is soldered to the mainboard. Use the Samsung Flowchart to test the components before replacing it.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
