In January 2019, Xiaomi CEO Lin Bin published a video on Sina Weibo, featuring him demonstrating a prototype smartphone with two flaps capable of being folded inward.[20] Samsung officially unveiled the Galaxy Fold during its media event at Mobile World Congress in February 2019.[21] Alongside the Galaxy Fold, the convention also saw other foldable phones being unveiled or teased, such as the Huawei Mate X,[22] and TCL presenting various prototype concepts featuring its "DragonHinge" technology (including a braclet-styled device).[23] LG did not unveil a folding device, citing a desire to focus more on re-gaining market share in the smartphone market.
