I noticed that my rezound has an option for WiFi direct. I connected to my wifes rezound using this WiFi direct but I'm not sure what exactly it does. I've tried to send pics and music from one phone to the other but I couldn't find an option to send via WiFi direct. Anyone have an idea of what this could be used for. I read that it works with WiFi printers but what else? My phone won't detect my smart tv or my computer. Although I'm not sure if its supposed to.
