This issue came up on the Replicant IRC recently. Here's a truncated

I'm curious, does nonfree software (via the modem) control the
microphone on the S2 and S3, or not?
Also, Have these hardware audits for currently supported Replicant
devices been published on Replicant's redmine somewhere? If not, can you
post on the wiki any notes that you took when you did these hardware
audits so that others can reference them?
Are there any legal issues related to us posting the images that Jookia
put in the chat in the wiki?
