Sorry we are not able to do this for you. We are a community of volunteers that share an interest in Android OS, Android devices and Android news. Many of us help people who come here fix problems on their devices or solve problems and unfortunately we do not have the power to effect options or features of specific phones or operating systems (OS).
We may be able to help you find a call recorder, there are many on the Play Store. Personally I like Google Voice. It offers a call recording feature that may work for you. Others may like other apps and maybe they will chime in with some suggestions.
