I am sorry. Android disabled the ability to record in Android Pie and I don't believe the function is available in Android 10.
I found this online. Please note we don't recommend anyone to root their phones.
"Google disabled the call recording feature in Android 10 by default, so
- If the manufacturer changes nothing, the phone needs root.
- If the manufacturer changes something to enable the call recording feature in a specific market area, the phone doesn't need root."
So I am sorry I cannot recommend any programs to you.
