My M30s doesn't have dual volte option in settings. A customer care executive told me that I'll get that option in upcoming update. I have received 2 updates already, however, that option is still not available. Samsung has cheated by saying that this phone has dula volte option. Also, the camera quality is very poor by the standards of 48 mega pixels.
