> It seems totally reasonable to me that arbitrary apps can't insert sounds into my call audio, am I wrong here?

No, though I will say I'm upset with how protected calls have become on phones in recent years. I used to record every phone call with an app so I had a record of it, something which is completely legal to do where I live, but that really isn't possible anymore.

Now all my calls go through a VOIP provider and call recording is a feature they offer.

I could never figure out how to get call recording to work on 3cx, after the end of android call recording.

So a trrs plug splitter I can record to a tascam. And use a fancy mic.

Still, nicer to press a big record button, by a lot.
