Forcing me to have this on my device-1 not allowing me to download samsungs app that synchronizes everything I have -3 stars. Over 2000 dollars in devices and Because the information is not provided I could not know this. There were other unadvertised things i should have known better,i have revised future device plans for myself and will just sit here disappointed because I can't use my 2k how I want. I doubt Vzon will all of a sudden switch course on it but ill change rating to 5, app is nice
