The default home screen of the Galaxy S6 and S6 Edge offers a grid of four icons by four icons. For some users, myself included, the default grid is not enough. Sure, you can add more panels and place apps across the various screens, but that involves a lot of swiping and tapping.
Luckily, you can change the grid size used across your home screens. The process takes just a few seconds to complete, well, unless you count deciding which apps to add to your home screen. We all know that process can take a while.
Unlock your device, and long-press anywhere on your home screen. Be sure not to do this on an app icon, as that will result in moving the app instead of bringing up the menu we’re looking for.
After a few seconds, your home screens will turn into thumbnails (more or less) and a row of buttons will appear at the bottom of your screen. Each button will allow you to change a different aspect of your home screen, but right now we’re only concerned with the button labeled Screen grid; tap on it.
You can then view a preview of each grid size, and get a feel for the size the app icons will be based off how many apps you want on the screen. When you find one you like, tap on Apply at the bottom and begin adding more apps to your home screens.
