I have been a RW subscriber, since September 2014, and have used a variety of the Motorola phones. I am currently happy with the Moto X4. I have been admiring the Note 9 and wondered if there are any unique issues with this phone & RW.
As with all Samsungs used with Republic, Samsung’s bundled Messages app does not work as it’s not updated to work with Republic’s blended WiFi/cell service. Republic supports Messages by Google or Republic Anywhere instead. Other than that I haven’t heard of any issues specific to the Note 9.
