We recommend installing an app called Shouter, which reads all notifications aloud.
It works very well! When you receive a text message, Shouter reads who sent it and the entire message, as well as emails, missed calls, etc. Additionally, with Google Voice Assistant, you can open apps by simply saying "open Outlook" or "open Messages," etc.
These two apps make this unit amazing, just like using a cell phone, without needing to connect a cell phone to it.
As to the favorite contact, we have improving it now, you could also update the firmware to the Vivid 12 which has the function.
