Samsung accidentally leaks its own tri-fold Galaxy G Fold
Images of an as-yet-unknown three-part Samsung foldable have appeared deep in One UI 8. There has been talk of a tri-fold from Samsung for some time, but this is the first time we have seen an image of what is to come.
Foldables are phones that fold shut. It doesn't matter if they fold horizontally or vertically. Most current foldables consist of two parts connected by a single hinge. However, there are plenty of other possibilities, as long as you think creatively. Samsung seems to have done just that with the upcoming Galaxy G Fold.

So far, we only knew that Samsung was working on such a device, not what it would look like. Would Samsung opt for the same solution as Huawei with the Mate XT Ultimate where one hinge bends outward and the other inward? A surfaced image deep in the One UI 8 code provides the redeeming answer to this pressing question.

We see a three-part phone whose ends fold inward. In this case, the left part should be on the bottom, with the right part folding over it. Of course, this strict order could cause problems, but that's a concern for later.
Screen is better protected
Another screen is located in the middle at the outside, whereas the Huawei has no secondary screen. Although it sounds cumbersome, Samsung is solving a real-life problem with this feature. A flexible screen is much more fragile than a fixed glass one. Once folded in, the flexible screen is safely tucked away, reducing the likelihood of scratches.

Because this Samsung model has three sections, it creates a much larger 10-inch screen inside than, say, the 7.6-inch display in the current Fold 6. The size of a full-sized tablet, in other words, but in your pocket.
You're folding it wrong!
It's not obvious from the pictures, but a specific folding sequence is required. First, fold in the left side, then the right. Folding the right side in first could cause damage, as shown in the image below. Samsung hopes to prevent this with an on-screen warning, but, of course, you can bet someone will carelessly do it wrong and face the consequences.

This immediately reminds us of Antennagate from the iPhone 4. Apple blamed the problems of dropped phone connections on users when in reality Apple had designed the antenna wrong. Steve Jobs allegedly answered a disgruntled customer with the words; "you're holding it wrong!".
We may get to see the G Fold during Samsung's Galaxy Unpacked event to be held July 9 in New York. During that same presentation, the unveiling of the Flip7 and Fold7 is expected, but perhaps this tri-fold will be shown at the end. Sort of like a "One More Thing."
