Samsung Galaxy Fold

The Samsung Galaxy Fold is an Android-based foldable smartphone developed by Samsung Electronics. Unveiled on February 20, 2019, it was 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.

The Galaxy Fold received mixed pre-release reception, with praise for its innovative design, but criticism over the device's durability and longevity, and it was concluded that the Galaxy Fold was a proof of concept device for early adopters rather than a device suited for the mass market. Due to issues with the device's durability and susceptibility to damage, Samsung announced that it would recall the review units and delay the release of the Galaxy Fold indefinitely while it addressed the problems. Samsung officially detailed its design changes in July and released the phone in September 2019. The company claimed to have sold one million units since launch by December 2019, but Samsung later denied having sold 1 million units, and admitted having reported sales expectations as actual sales. A second generation model, Galaxy Z Fold 2, was announced in 2020.
