If you read page 91 in the user's guide that is available online via sprint and samsung, they have a note stating that the text messages can be started in voice command and then will remain in voice mode to input text messages. I have yet to have the voice mode work. I can start a text via voice command, but not actually input the text using my voice, i have to manually type it. I called samsung they said to call sprint. I called sprint they claim it had to be an added feature service that is no longer available. The SPH-A900 has the feature at no extra cost, it's a phone feature not a service feature. Has anyone got this voice mode to work on the instinct? Thanks!
