Wait If You Want a Massive Display
The Galaxy Fold's biggest draw is the display.
In place of your typical flat or curved screen in the 5-inch to 6.5-inch range, the Galaxy Fold comes with an internal 7.3-inch foldable display. Samsung calls it the Infinity Flex Display. The internal display features 1536 x 2152 resolution. If you're looking for 4K quality, you'll need to look elsewhere.
The magic here is the folding mechanism. The Galaxy Fold's internal display folds in the middle which provides a tablet-sized screen into the body of a phone.
The Galaxy Fold's display size should appeal to those who love to play games or get work done on a big screen at home or on-the-go.
Samsung's software provides additional perks including a Multi-Active Window feature that allows you to use three apps on the screen at the same time. In other words, you can monitor your messages, watch a YouTube clip, and get work done at the same time.
If you no longer want to use the Galaxy Fold like a tablet, the device's display folds up and you get a 4.6-inch HD+ display on the front of the phone.
Samsung's built-in App Continuity means apps will switch between screens as you open and close the device.
This obviously isn't for everyone, but if an all-in-one (tablet + phone) is something you're interested in, think about hanging around for the Galaxy Fold.
