Last week we were amazed by the Oppo X 2021. It's a concept smartphone that doesn't need a hinge to transform into a tablet.

This seems like pure magic, as the screen adapts to what is on it:

If your first reaction when you see this clip is that Samsung would pursue such a design instead of bending the screen like the Galaxy Z Fold 2 If that was what you wanted, you may be in luck. Ice Universe, a leaker with a very strong track record on Samsung predictions, has hinted that the company is working on something very similar.

Ice Universe captioned a photo of the Oppo X 2021 prototype with the caption "Galaxy Z Fold S (In&Out folding)," followed by a second tweet that read "Galaxy Z Fold Scroll."

This is actually not the first time we have heard of the Samsung Galaxy Z Fold S, but when the name was first leaked in September, it was a very different product, designed similar to the Microsoft Surface Duo, with a single OLED screen and 360-degree hinge It was rumored to have a

While that possibility still exists, the idea of a scrolling ice universe certainly seems more likely. The scrolling design has distinct advantages. Samsung's Galaxy Fold device has a slightly distracting fold in the middle, but Oppo's prototype reportedly avoids this.

On the other hand, it is important to remember that Oppo's handset is just a concept and Samsung has not yet reached that point. The Galaxy Fold was launched with many problems, but it exists as a product that can be purchased right now, and now that it is in its second generation, it works very well. Who knows how reliable the scrollable motorized elements will be in extending the phone over the years. And can scrolling displays really stand up to the kind of abuse they are subjected to?

These questions are the reason for the long R&D cycles of new technologies, and perhaps also why there is no launch date in sight. For now, the best option for a 2-in-1 phone and tablet remains the Samsung Galaxy Fold 2 or the Galaxy Z Fold 3 if it can wait until next year.
