When I tapped the charger NFC to my I9505G (Google Edition S4) it downloaded the Gear Manager Stub and setup the device without issue.
The problem I'm having is when my Gear is connected it seems to screw up the Physical Keyboard. I lose access to the keyboard in all my other apps. In Language & Input my Physical Keyboard is listed as SA_MUSIC_REMOTE_CONTROL
Easy Fix - Just Turned Off Physical Keyboard , appears it was trying to use the GG as a keyboard via Bluetooth. All is well. Working with very little pain on the Google Edition S4.
Now I just need to see if I can find the Weather Widget and Pedometer
