When I received my S7, the rep told me that I could use the Smart Switch app to move files from my S5 to the new phone. I couldn't download the Smart Switch app because it isn't compatible with the S7. I ended up manually moving the files. Yesterday, I stumbled upon Smart Switch in my S7! It's built into the S7 and hidden in the settings. Go to Settings > Backup and reset. It's the first option. Go figure.
