@UniverseIce has provided another comparison between the Galaxy Z Fold3 and the Galaxy Z Fold4, the latter being one of two foldable smartphones that Samsung is expected to release in the autumn. Previously, the leaker claimed that Samsung has made the display crease less visible this year, a feature of foldable smartphone displays that no company has eliminated yet. Also, @UniverseIce informed their followers that the Galaxy Z Fold4 would have a squarer aspect ratio than the Galaxy Z Fold3, discussed separately.
Now, they have shared third-party Galaxy Z Fold4 cases, embedded below. Presumably, the unnamed case manufacturer has based their designs on CAD renders, such as those leaked earlier this month by @OnLeaks. For some reason, the case retains a pronounced camera cut out, even though the Galaxy Z Fold4 is rumoured to feature individual camera lenses with no larger camera housing. Still, the cut-out highlights that the Galaxy Z Fold4 has a relatively short body, at least compared to the Galaxy Z Fold3.
Additionally, the camera appears to confirm that the Galaxy Z Fold4 is wider than its predecessor, which should make its cover display easier to use when closed. To that end, @UniverseIce has compared the case design with a comparable one of the Galaxy Z Fold3. In short, it seems that the Galaxy Z Fold4 will be closer in design to the Oppo Find N, albeit while retaining its predecessor's overall look. For reference, the Galaxy Z Fold4 is believed to measure 158.2 x 128.1 x 6.4 mm, 0.7 mm thicker than the Galaxy Z Fold3.
