It's strange that you can't get the app to download. I gave my S7 to my son. I was able to get ahold of it yesterday and the current version of the GoPro app is installed and runs fine.
If all else fails, you can get a microSD to microUSB adapter on Amazon for pretty cheap. It will allow you to transfer media from the card to your phone. Another option is to just insert the camera SD into the expandable SD storage slot in the phone. I don't know exactly if that will work because the card isn't formatted for the phone, but it's worth a shot if nothing else works.
