The Samsung Galaxy Z Flip 4 and Samsung Galaxy Z Fold 4 are scheduled to be released this year.

A USB Type-C port, a main microphone, and a speaker grille are all included on the Samsung Galaxy Z Flip 4.

The screen dimensions in both open and closed mode are the same as its predecessor, and it seems Samsung hasn’t really tried to make a lot of changes, especially when there wasn’t much to complain about.  

Color selections for the phone aren't as exciting as the new engineering work that's going into it, but they're still significant for how the phone looks.

We just know one rumour about the Z Fold 4's power source, and it's a bad one. According to the report, Samsung will maintain the battery size of the Galaxy Z Fold 3 around the same.

One of the worst aspects about foldable phones is that they have a far higher screen-to-power ratio despite having a battery that is the same size, or even smaller, than comparable phones.

The battery life of the Z Fold 3 isn't great, but if Samsung doesn't change the battery capacity, it'll have to make the phone more efficient in other areas to make it last a whole day without a charger.

On the Z Fold 4, it would be fantastic if Samsung supplied better cameras in general. Although photography will not be a priority for Samsung's foldables as it is for its Galaxy S phones, larger or higher quality sensors would be welcome. It would also be wonderful to have a more powerful Space Zoom.

The S Pen stylus was first introduced to Samsung's foldables with the Z Fold 3, so it would make sense for the company to build on that with the next-generation device. Hopefully, Samsung will be able to integrate the stylus into the body of the Galaxy Z Fold 4 like the concept design above, rather than requiring you to store it separately or in specially designed cases once more.

The biggest disadvantage of watching content on foldable displays is that the visible creases in the screen can occasionally detract from the viewing experience. We don't anticipate the crease to vanish completely, but it would be wonderful to see it blend in a little more.
