REQUIREMENTS

1. You will need to check the About Device menu and make sure you are running the latest Lollipop software update with the number 5.0 and up.

2. You don’t need root access to follow this guide. In fact, we want you to be running the stock Android with TouchWiz UI for Lollipop and nothing else. If you
are running a custom ROM you should probably return back to stock firmware to make this work for you.
