Ice universe via his Twitter page shared pictorial information (in form of protective cases) of the Samsung Galaxy Z Fold 4. From deductions, it is obvious that there isn’t much change on the coming Z Fold in comparison with last year’s model. The cases for the Z Fold 3 and Z Fold 4 have the same camera cutout and are quite similar in size.
One area where we could note some change is with the size of the outer display. The Galaxy Z Fold 4 will have a larger outer screen size than its predecessor. Asides from this, the pictures give away no further detail regarding the coming foldable device from Samsung.

Previous tweets from Ice universe also gave away a few other changes that we can expect on the Z Fold 4. The hinge on this coming foldable will dramatically improve. Instead of the previous protruding hinge, we will see a more flush finish to the hinge.
Also, according to the leaker, its crease will reduce but not disappear. Another improvement that Ice universe pointed to is the weight of this coming Samsung foldable. It’d weight about 254g, which is a notable improvement from last year’s 271g foldable.
Already, the processor of this device has surfaced in recent leaks. It’d make use of the Snapdragon 8 Gen 1 processor and similar storage configurations with last year’s foldable. The price of this device might as well reduce in comparison with the Galaxy Z Fold 3.
For now, the launch date of this foldable device isn’t certain, but we know that it’ll launch alongside the Galaxy Flip 4. The coming Galaxy Flip smartphone will as well feature some notable upgrades. Specifications and prices of these devices will be made known by Samsung during or before the launch event.
