Easily Switch From Apple to the Galaxy S7
Whether you have an iPhone or another Android device, switching to the Galaxy S7 is amazingly easy thanks to a little tool inside the box. It is a little white dongle (pictured above) that plugs into the micro-USB charging port, and it transfers virtually anything and everything from an old phone to the Galaxy S7. The app, Smart Switch, makes this incredibly easy and straight forward.
When your first setup the phone (or if you want to redo it) this is how you should proceed. Full instructions for setting up the Galaxy S7 completely, and using Smart Switch can be found here.
