Samsung first teased its foldable phone back in November, and at the company’s Galaxy Unpacked event today it’s further detailing its foldable plans. Samsung’s foldable now has a name, the Samsung Galaxy Fold, and the company is revealing more about what this unique smartphone can do. Samsung is using a new 7.3-inch Infinity Flex Display that allows the phone itself to have a tablet-sized screen that can be folded to fit into a pocket.

The main display runs at 1536 x 2152 resolution, and when it’s folded, a smaller 4.6-inch (840 x 1960) display is used for the phone mode. Samsung is using 512GB of Universal Flash Storage 3.0 (eUFS) for fast speeds, alongside a 7nm processor and 12GB of RAM. Samsung has even built two batteries for its Galaxy Fold, that are separated by the fold but combined in the Android operating system.

Samsung has built a sturdy backbone to the device, with a hinge system that has multiple interlocking gears. All of these gears are hidden at the rear of the device, and allow the Galaxy Fold to transform from tablet to phone modes. Samsung is creating four different colors for the Galaxy Fold, but it’s the main tablet display that’s key here.

Samsung is allowing the Galaxy Fold to run three apps at once on this Android device, and it’s using an app continuity system to adjust these apps when you move between tablet and phone modes. Apps like WhatsApp, Microsoft Office, and YouTube have all been optimized for the new display and modes, and Samsung has been working with Google to ensure Android fully supports this display.

Samsung isn’t the only smartphone maker creating a foldable device. Xiaomi teased its own folding phone recently, that looks like the best concept we’ve seen so far. Huawei is also reportedly planning to release a foldable handset this year, and Lenovo has started to tease its own prototype. LG has also been developing flexible OLED displays and TVs that roll up into a box.
