You can change the grid layout for apps on your home screen. Select from 4x4, 4x5 and 5x5 options.
These options will rearrange and resize the Icons.
How to change the grid size
App icons may shift to the next screen or there may be blank sections depending on what option you are switching to and from. This is expected.
If you choose the 5x5 app arrangement, the size and spacing between app icons are minimized, allowing you to view more apps on a single screen.
