I downloaded the gopro app for my Samsung tablet a week or so ago and it works letting me control camera and see what the camera sees. Today I decided to download the same app to my Samsung cell phone although I had trouble doing it. . It also works the same. It's the black square with white GOPRO and 4 small colored squares below Gopro. A few hours later I see another icon next to that that shows the gopro camera. It's called gopro wifi. If I open it..it says DiRAMa gopro wifi control. What is that? I only downloaded one thing that I know of and only it showed on phone awhile later. I haven't tried using it.
