FlexPai is a foldable smart phone that can be easily folded and unfolded. It is a combination of phone and tablet, which can perfectly solve the long-term contradiction between big screen and portability. FlexPai only needs a set of cameras to achieve folding shooting and self-timer. The "flowing" design concept of the Royole self-designed Water Operating System allows applications to adapt to different screen sizes in different states of folding and unfolding; It embodies the concept of "inseparable science and art".
