Citation needed. My Pixel 7a with the latest updates has settings for call recording in the phone app. Since I never screwed around with it, I'd assume these are the defaults:
Call recording is turned on, with "asks to record calls" set
Automatically delete recordings is "never"
Automatically record calls with non-contacts is off
No specific numbers to automatically record calls are set
There is also a note that you have to agree to their ToS to use it, and I'd also suggest being careful if you live in a jurisdiction that requires two-party consent for recording.
In any case, I'm of the opinion that if F-Droid goes, I'm basically going to treat this as a feature phone and stay away from third-party apps in general aside from "musts" like banking.
