Apple gives us more control over our homescreens in iOS 14 with features like widgets and the app library. You can also change your iOS 14 home screen if you don’t want multiple pages.
Change the iOS 14 home screen
This tip came because I was trying to figure out how to do this.There is a Home Screen section in Settings that lets you control where app downloads go, but not change your pages. But I got it.
That particular home screen page will then disappear. If you want to bring it back, just repeat the settings. Your apps and widgets will be saved in their previous positions.
