The phone starts at $1,980, but sales tax and other possible fees push the price tag to more than $2,000. We've estimated the cost plus tax in several US cities so you won't be surprised at checkout. (Editors' note: These are estimates. Actually costs may vary.)

The Fold has a 4.6-inch exterior display and it can open up to a full 7.3-inch screen. The app you had open on the small screen will also show up when you unfold the phone -- Samsung calls it app continuity. With the phone, you can use one app in full-screen mode, open up two apps vertically, or open a third panel.
