I assume your text messaging works as well?
I have a Galaxy S4. I just got to learning about how to pair my phone up. A few weeks ago, I tried and it wasn't working. No phonebook or numbers, no text, but at some point I had texts, then lost them.
Anyways, I performed a reset, and removed the phone from the car. The dealership did it the first time to show me how to do it. So I did it myself, and it's flawless. Texts and phone calls are great in this car. The engine is better though.
