A new video has given us our first look at the upcoming Samsung Galaxy Z Flip4, the next model in Samsung's big-selling folding phone range.And though it appears to be an incremental update overall, there are some notable differences in the design, not least a much less obvious crease.

Flip4 Hands-On

The information on the Fold4 comes via a video from the YouTube tipster TechTalkTV, who was able to get hold of the new device. The video has now been removed, but XDA caught all the details.

The phone will share a similar look to its predecessor, the Flip3, but offers improvements in some key areas. Chief among these are a redesigned hinge that is both smaller and reportedly helps the phone feel lighter. And the most controversial part of folding phones, the crease, is also said to have been reduced. It's still evident, but much less so than before.

The leaker also reports that the phone's outer display is larger than on the previous model, although not obviously so—they suggest that you won't really notice the difference unless you put the two devices alongside each other.

This latest leak adds more to the growing rumors surrounding the Flip4. The phone is expected to be powered by the new Snapdragon 8+ Gen 1, with 8GB of RAM. Unlike its sister device, the Galaxy Z Fold4, it should also have a slightly larger battery, which could help to address the other main concern about the range.

There's a lot of buzz around the Flip4. The Flip3 was a big success, exceeding Samsung's own sales forecasts and grabbing around 50% of the market share for foldables in the process. While so much of the attention among tech enthusiasts focuses on the flagship Fold range, the more pocketable size of the Flip series is what could help push foldables into the mainstream.

Twitter leaker Jon Prosser has suggested that the Flip4 will be unveiled at a launch event on August 10, alongside the Fold4 and a new smartwatch, the Galaxy Watch5.

Will the Fold4 Be a Hit?

It remains to be seen whether the changes in what's looking like an incremental update for the new Flip phone will be enough to continue its record-breaking success. But there's no doubt that the issues related to the still-fledgling hardware design—the crease in the screen, the bulky hinge, and the mediocre battery life—have been holding it back.

If those things are on the way toward being solved, then Samsung could have another hit on its hands.
