Samsung Galaxy Z Flip3 5G (2021)

A folding clamshell body gives the Samsung Galaxy Z Flip3 5G a compact shape when closed and a conventional smartphone-sized display when opened. The 6.7-inch main screen folds inward, while a separate 1.9-inch cover screen remains accessible on the outside. That smaller display provides notifications and quick controls without requiring the phone to be opened for every interaction. Cellular connectivity includes 5G.

The design suits people who value pocketability and a distinctive appearance but still want a large screen for media and everyday apps. Its hinge also allows the phone to rest partly folded for supported hands-free uses. IPX8 water resistance is a notable feature, although that rating does not establish dust protection. What sets the Flip3 apart from a standard slab phone is the way it changes size between carrying and use, with the cover display handling brief interactions while the main screen remains protected inside.
