Smartphones with folding displays or "folding menus" are a new category of mobile devices that combines the best parts of a smartphone and tablet into one device. At this year's Mobile World Congress, there are numerous announcements from various smartphone brands that populate this emerging category.
While the Royole FlexPai was the first device that came onto the market with a foldable display, it was recently shown at the CES 201
What is a foldable
Google's Android developer blog referred toon these devices with foldable displays as "foldable " ] "Simply put, these are devices that allow you to run and seamlessly switch apps in two configurations (smartphone or tablet).
When a user has a collapsed display opens, optimized apps switch from a portrait mobile layout to a tablet-friendly landscape layout either on the same display (when it's unfoldable) or from a vertical display to a horizontal display on the inside of the foldable.
From what we've seen so far have s in three categories of folding devices.
The China-based Royole previously introduced his FlexPai. This is an outward-folding device that requires the display to be unfolded to display a tablet-like interface with scaled apps that display more information or data. The Huawei Mate X follows a similar approach with an outward fold. The advantage of an outwardly hinged display is that it folds out flat when viewed in a tablet layout. Theoretically, the display is less prone to wrinkles as it rests on the folding mechanism.
The disadvantage of this folding mechanism is that it always leaves the rear side of the window wrinkles (when closed) exposed to scratches, since you need to leave the phone on a table or bench and the surface does not necessarily have to be smooth. Another problem you need to think about is how to attach a case to such a device. Do you use panes of tempered glass everywhere? What happens to the flexible bit?
Next comes the inner fold, the more complicated of the two. Samsung has followed this approach with its Galaxy Fold device, a device that has a smaller display on the outside of the fold and a larger one on the inside.
The Galaxy fold opens like a book. Although it may seem simple, the mechanism for supporting an inwardly folded display is complicated because it must protect the display by maintaining the central curve. It also takes the strength to protect the display when someone accidentally sits on the phone. This is because the display can not fold beyond a certain point.
This also leads to a thicker smartphone design, but the design protects the screen from scratches.
Recently, Xiaomi created a two-fold prototype device, resulting in left, right, and middle regions. The video, disgusted by co-founder Lin Bin, shows a uniquely-looking device with a fold on either side of the main display area. Both sides are fold-out to form a tablet-like display that expands the viewing area. The device can then be folded into a compact smartphone-like form factor and put in a pocket.

Since Xiaomi has not made his folding device. not yet officially, and Oppo only presented a prototype we take a look at what the new series folding parts of Huawei and Samsung on offer and how they compare.
It should be noted, however, that this is not a comparison to judge the performance, but only to give our readers an idea of what is going on between the two unpublished devices that are up around MWC in 2019 the market came, is different. Smartphone

As can be seen from the table above, Huawei offers the practical (almost without bezel) folding display that not only folds flat larger 8-inch table-like display, but also has no interference notch like the Galaxy F old do.
The Mate X is designed purely on the specifications on paper and offers in comparison to the Samsung Galaxy Fold also has a higher sensor pixel number and the same applies to the battery.
Samsung's inward-folding display is rugged in design, though both devices have not yet announced IP rating. So, if you want to buy one and jump into a pool, you're in better hands with the recently introduced Galaxy S10 (19459006) or the Mate 20 Pro
One detail to note was that Samsung introduced the UI of the device, which was developed by the Android developer community. At the same time, Samsung has made little mention of the size and weight of the Fold, even if it looks compact compared to the larger dimensions of the Mate X. The Mate X weighs just over a quarter of a kilo (298 grams).
It remains to be seen how apps respond and how well third-party apps switch from a smartphone layout / smartphone configuration to a tablet interface. What's mentioned in my article on Galaxy Fold also remains to be seen: how soon will developers support these apps, a fragmentation issue that has been plaguing the Android platform for a long time. Everyone's been waiting for years to see something new from the smartphone industry and make these mobile computing devices interesting and entertaining after the iPhone has inspired all smartphone makers to embrace their creativity and their courage.
And after all the camera-pop action, Foldables certainly sound interesting even if they cost more than $ 1,500. While many of us can not afford these ultra-premium devices, those who have been waiting for an iPhone XS Max equivalent (from budget) have finally had the choice.
