Samsung may be the most powerful brand to commit to a foldable phone, but it isn't the first. You can already buy the ZTE Axon M, which doesn't have a flexible screen but rather two screens side by side connected with a hinge. There's also the FlexPai, from the small startup Royole. Unlike the Axon M, it's equipped with a single bendable, flexible screen.

Having reviewed the Axon M and handled the FlexPai, I'm excited to see what the Galaxy X has to offer. A flexible phone made from a company with the money, resources and clout like Samsung would hold a lot of promise. In the meantime, here are four important takeaways from ZTE and Royole's phones that Samsung should heed if it wants its foldable Galaxy X or Galaxy F to stand a chance.
