It seems like many companies in the smartphone industry are moving toward developing foldable smartphones. There are two real devices so far: Samsung has announced the Galaxy Fold and Huawei is building the Mate X. Oppo is experimenting with a foldable prototype that looks like the Mate X; Motorola is planning an all-screen revival of the Moto Razr; and Xiaomi has teased a crazy prototype with two folds in the display. Even Corning is working on a flexible glass cover to someday protect all these devices from scratches.

With so many manufacturers trying out the foldable smartphone form factor, there are a number of implementation ideas. While Samsung already has the Galaxy Fold, a new report from Bloomberg claims that Samsung isn't putting all its eggs in one basket. The company is reportedly tackling three different foldable form factors.
