This new UI update has ruined the quick functionality of the previous UI, and now I have to rebuild the home screen as the new UI has reverted to the factory defaults. NOT NICE! 

To use an app, now we have to slog through the entire list of apps rather than the quick, I'll call them "favorites" pages, only seeing the entire gamut of apps by swiping down. I'm guessing we had to dumb down the interface to cater to this new generation, yes?

Long time Samsung user, not happy AT ALL with this update to the UI.
