I have an stl-003 unlocked on t mobile.I did OTA download of 4633.Everything went well it was on charger whole time ,it asked for restart I did it.Now i have a new icon that says Wifi calling ie.UMA .But i can't toggle it.Its says on but its greyed out.Under the word Wifi Calling it says error .Anyone else seen this.Does it mean the OTA did not download correctly.Everything else works well.
