The successor to the Galaxy Z Flip 3 is expected to launch alongside the Galaxy Z Fold 4. Both foldable phones are rumored to have major design upgrades, including a larger screen cover for the Galaxy Z Flip 4 clamshell and a new hinge with a thinner build for the tablet-sized Galaxy Z Fold 4. Apart from the foldable smartphones, Samsung may also introduce the Galaxy Watch 5 at this event. The smartwatch is rumored to have a temperature sensor and longer battery life compared to its predecessor. Samsung did not immediately respond to a request for comment.
