Do note that the Galaxy Z Fold 4 render is based on the information the tipster has, it’s not an actual leak of the device. As you can see in the provided image, the Galaxy Z Fold 3 is slightly taller.
The Galaxy Z Fold 4 will be shorter & wider than its predecessor
The Galaxy Z Fold 4 will have a shorter and wider display aspect ratio, and it’s possible it will be slightly wider overall. It is worth noting, though, that its hinge will take up less space, so the phone’s physical width will decrease slightly because of it.
The Galaxy Z Fold 3 has a display aspect ratio of 25:9. The Galaxy Z Fold 4’s display aspect ratio will be 23:9, according to the tipster. That is the difference he tried to present in the provided image.
The overall design will be quite similar, though, it seems. You’ll notice that a display camera hole will be placed on the cover display on both phones. Their bezels will also be similarly thick/thin, not counting in the hinge, of course, as the hinge will be smaller/narrower on the Galaxy Z Fold 4.
The Galaxy Z Fold 4 is tipped to launch in August
Samsung is planning to announce the Galaxy Z Fold 4 later this year. The phone is expected to launch in August, alongside the Galaxy Z Flip 4. Samsung still didn’t confirm their launch date, but considering the Galaxy Z Fold 3 and Z Flip 3 arrived in August, there’s a good chance their successors will as well. That’s when Samsung usually hosts its second Unpacked event of the year.
The Galaxy Z Fold 4 and Z Flip 4 won’t present major design changes, but will be improved compared to their predecessors. Samsung is, first and foremost, expected to offer hinge improvements, to decrease the display crease on both phones.
