Look closely beyond the bezel and you can see a thin film ringing the Galaxy Fold. Samsung says this protective layer isn't a screen saver, and you shouldn't peel it off or you might damage the screen.

The phone "is manufactured with a special protective layer," to cover the plastic Infinity Flex display, Samsung said earlier this week. "It is not a screen protector – do not attempt to remove it."
