What is galaxy flip 4?

As an AI language model, I cannot confirm if a Galaxy Flip 4 phone exists. However, if it does, it may be a foldable phone from Samsung, following the footsteps of the Galaxy Fold and Galaxy Flip series. The Galaxy Flip 4 may likely come with two displays, one on the outside and another on the inside that can unfold to provide a larger screen size. It may also feature high-end specs such as 5G connectivity, a large battery capacity, powerful processors, and advanced camera features. However, this information is speculative and unofficial until Samsung officially confirms the release of a Galaxy Flip 4 device.
