Is there an app that really blocks SMS text from blacklisted numbers? Avast is working on their software, since Google broke text blocking with KitKat. But has anybody already released software that really works with KitKat? (I used the Nexus 5 SMS app on my Nexus 7 in order to restore SMS, but along with good text is a lot of spam. Go SMS Pro does not work for me, it will only save drafts, not send or block.)
