I apologize for the inconvenience. I'll refer you to an earlier post I made: http://forums.cnet.com/7726-13973_102-5306779.html
I have been using Samsung Remote app on my iPhone 4 with iOS 5 for a long time now. But as soon as I updated the OS of my iPhone 4 to iOS 6, it stopped working.
The app disconnected from TV after every 20 seconds of connection.
I am not able to perform any action with the Samsung Remote app now.
Please help me with this issue.
