The Samsung Galaxy Fold is an Android-based foldable smartphone manufactured, developed and designed by Samsung Electronics. It was unveiled on February 20, 2019 alongside the Galaxy S10 series, the Galaxy Watch Active, the Galaxy Fit/Fit e and the Galaxy Buds, and released globally beginning on September 6, 2019. The device is capable of being folded open like a book to expose a 7.3-inch tablet-sized flexible display, while its front contains a smaller “cover” display, intended for accessing the device without opening it. With the announcement of the Galaxy Z Flip, a foldable in a clamshell form, Samsung's foldable phones were made part of the Galaxy Z series. This also retroactively applies to the Galaxy Fold.
