On the LG G5 all of your apps are now on select home screens.
The first screen is your main Home screen (excluding optional Smart Bulletin screen if enabled/available).
Swipe across the screen from right to left to see the apps on the phone.
Apps appear only one place on the home screens.
Home screen edit mode
Press and hold an empty are of the Home screen to open Edit mode. From here you can change the order of your screens, select a wallpaper, select widgets to add, or navigate to the Home screen settings menu.
Home screen layout settings menu
You can change the grid size, how apps are sorted, add Smart Bulletin home screen (if available), and to hide apps in the layout settings menu.
Navigate to Settings> Display tab> Home screen.
Scroll down to the Layout section and select from the respective options.
When you select to sort apps alphabetically, the folders sort first then the apps. Any of the widgets on the screens will remain positioned where you place them. The apps will wrap around the widgets.
