Samsung's Galaxy 4 hits the market on April 26th, with a price of $1,980.
So what do you get from a bending phone that cost nearly 2,000 bucks?
A total game-changer.
When it's closed, the fold has a 4.6-inch screen, and then it opens like a book to 7.3 inches.
The screens themselves are made from a plastic polymer material, not glass.
That's what lets them bend like they do.
But this model doesn't close completely flat.
There's always going to be a bit of a seam.
The Fold runs the most recent version of Google's Android operating system, the Android 9 Pie.
The two companies work closely to ensure a seamless user experience called ad continuity So when you're looking at an app on the smaller screen, it will automatically fill the bigger screen the phone is at its largest.
When the phone is opened to work more like a tablet, you could have three active windows working at once.
And in total, the Fold has six cameras, and will be available in four different colors.
