Samsung has long been rumored to be making a folding phone, currently known as the Samsung Galaxy X, and it looks like the handset might land in the first half of 2019, yet we might get a folding phone from Huawei even sooner.

According to “analysts and industry sources familiar with the matter”, speaking to Nikkei, Huawei has partnered with panel supplier BOE (a company which also supplies components to Apple) to launch the handset in very early 2019.
