Samsung is preparing for its much-awaited Galaxy Unpacked event, set to take place on July 26. The primary focus of the exhibition will be on the most recent additions to their collection of foldable phones: the Galaxy Z Fold 5 and the Galaxy Z Flip 5. Samsung has released a teaser film that provides a glimpse of the color options for its highly anticipated flagship clamshell foldable phone. The movie also highlights the revised hinge of the device.

An important characteristic seen in the teaser is the conspicuous lack of any space between the folding sections when the Galaxy Z Flip 5 is in a closed position. The anticipated enhancement is projected to be the most notable distinction between the latest iteration and its forerunner, the Galaxy Z Flip 4.
