Very basic and not great

- Need improvements to the dialer....the current design is dull and less intuitive...

- Need deeper and seamless integration with the Contacts list to allow for automatic use of Hangouts/Google Voice, for international calls (like in Android)

- Need better ring tone options...it just doesnt work...

- Need a conference call feature...

- Need full blown sms features- message forwarding, international sms support, sharing Apple passes etc....
