I didn't find this function on my 9500Pro in the stock calling app. On the other hand, this function is present out-of-box on 9500 and it becomes enabled on active call session (recording button appears). It would be great if Blackview engineers add this very handy and useful function to future updates for 9500Pro as well. Thanks.

You can use tons of 3rd party apps to do such thing, just do a little search in the play store

I know that, but 3rd party are either paid, or contain a lot of ads, or from suspicious developers (or all of this =) ). This function from phone manufacturer would unlikely be paid or ad-driven. And I have to trust the manufacturer as long as I'm using a device from it. So this any function out-of-box (especially such privacy-sensitive) would be much more convenient. I know that for sure as BV6000 owner (where it is present).
