No empty home screen panel is allowed to exist. If the icon,
widget or folder is the only item on the current home screen panel,
the panel will be deleted as you remove the item.
To adjust the order of a home screen panel:
1. Touch and hold an empty area of the home screen and slide
left or right to view the home screen thumbnails.
2. Touch and hold a thumbnail and drag it left or right to the
place you need.
