If it's the only icon under the page counter it's in the center. Move the two folders and Samsung music icons up one row or remove them from the home page entirely since you have the apps button
So it's not possible to have other icons alongside a centered apps button? I wanted to give the stock Samsung launcher a shot since I ditched it for Microsoft Launcher many years ago when it went into beta. It's strange to think that something like this isn't present despite every other brand I can think of has this option.
It migrates to the right most spot at the btm of whatever your viewing orientation is so you will always know where the apps drawer button is no matter how many other icons or widgets you have on how ever many home pages you have. You could just select the show apps button toggle and turn it off and just swipe up for the apps screen or make a folder with all your apps, label apps drawer or apps button or whatever and use that instead of the button.
