Panels on the Edge of the Screen
Samsung kept the hidden panel on the edge of the screen, a feature that has been used even after it discontinued the curved displays on its Galaxy phones.
This panel can have anything from app shortcuts to your favorite contacts, so you can have them on speed dial. You can access these panels from any app, making it easier to open a new app without having to go back to the Home Screen.
As you probably already know, the iPhone doesn’t have anything like that. It would be cool if Apple added a small panel with a list of shortcuts or features you can access from anywhere.
Sure, you can use the Control Center, which is already useful, but that’s not quite the same.
