I've read other posts where folks have issues with visual voicemail on graphene but my issue is this, when on stock software vvm, call screening etc work great, on graphene they do not. I'm self employed and obviously use my phone for business but for some reason I get multiple spam calls almost daily, to the point I'm back on stock to fight them off. I've tried installing the Google dialer but not running as a system app I'm guessing prevents vvm and call screening from functioning properly. Does anyone have a solution? Thanks.
