For those of you who want to experience the latest Samsung Galaxy S8 launcher and Bixby on your Samsung phone, you can grab the Galaxy S8 Launcher and Bixby APK below.
Now, for those of you with a Samsung Galaxy S7 or S7 Edge, you do not need root to install this, simply install both APK files and you should be good to go so long as you are on latest Android 7.0 Nougat.
