Re: Blocking texts/calls
Welcome to Android Central! It may depend on if you're using a specific app to block, or if you're using the stock Android function of making a contact always go to voicemail (found in the People app if you select a contact and tap Menu). If you select a contact to always go to voicemail, I don't believe you hear the phone ring--but you should get a notification for a new voicemail. Not sure if you get a Missed Call notification.
