I'm having huge problems with this right now. I was using an automatic call recorder, but my phone camera broke, and my carrier was limiting features due to the age of the phone. I broke down and upgraded. Big mistake! Call recording was utterly broken and will not work on that phone. Bought a different phone the next day... also broken. Can't seem to root either one. I'm out about $400 on this whole ordeal, and still can't record my calls again. I'm about to send Google the bill for these phones and the 12+ hours of my time that's been wasted because apparently Google has made call recording impossible on android 9 and 10.
