We got a chance to check out Royole's FlexPai foldable phone late last year, but we got an updated look at CES 2019. This year could be the year of the folding device, with Samsung also looking to launch their own flexible phone-tablet hybrid. And though Royole technically is the first to reveal their foldable phone, as of now, there are still some issues to work out before we can throw our endorsement behind it.
