Samsung today announced the Galaxy Fold, the company's first commercial phone with a flexible display that folds in half. Folded, it resembles a thick smartphone with 4.6-inch display; unfolded, it approximates a tablet in size and form factor, with a 7.3" "Infinity Flex" display. App Continuity allows users to start an Android app on the outer screen, then open the phone and continue uninterrupted on the larger screen. The inner screen also supports up to three apps side-by-side. It's powered by a Snapdragon 855 processor with 12 GB of RAM, and comes with 512 GB of storage. It also supports UFS 3.0 for faster storage access. Its two batteries total 4,380 mAh. It has six cameras and a fingerprint reader on the side. The 4G LTE version will go on sale April 26th for $1,980, and a 5G version will also be available. The Galaxy Fold comes in Cosmos Black, Space Silver, Martian Green, and Astro Blue, with choice of hinge color for further personalization.
