Being able to close your phone also makes it feel more private.

Since the Galaxy Z Flip snaps shut like a flip phone, the main screen isn't visible when the phone isn't in use. That certainly feels more private than having my phone's lock screen light up with notifications, letting the world around me know when I've received a new text message.

The Z Flip does have a small screen on its cover for viewing the time, notifications, and other information. But it's too tiny for onlookers to see from a distance.
