Since this is the same interface as the S8's, you get an updated launcher
where accessing the app drawer is done by swiping up or down on the home screen, with the option to remove the apps button from the home screen dock.
It brings a refreshed interface with optional
app drawer, more intuitive
access to settings (you no longer need to dive through 50 screens to get to
where you want to be), as well as standard Nougat additions like multi-window support.
