I'm currently on Verizon using a Galaxy S3 which would be a hotspot. I'm thinking about connecting another device with HDMI out to my 780p tv. Mostly I want to watch some YouTube and surf the Web with a MiniSuit bluetooth keyboard. The Samsung HDMI connector would work fine for this phone, but not for my wife's rezound. Another device I could leave plugged in and we both could use it. Thanks.
