If you have any of Apple’s latest handsets with rounded-corner displays, such as the iPhone X, XS/XS Max, or XR then chances are you’re familiar with the tiny Control Center grabber that appears at the top-right corner of the Lock screen, as depicted above.
For whatever reason, this grabber doesn’t appear anywhere else in iOS besides the Lock screen; yet you can invoke Control Center from anywhere by swiping down from the top-right corner of the display.
