The folded version of the Royole phone costs about 1380 euros in Europe, and when unfolded the screen has a diagonal (7.8 inch) tablet, but it can bend, and then you can use three screens: face, back and edge.
The FlexPai weight, 320 grams, is well above the iPhone XS Max and Galaxy Note 9, which are around 200 grams. FlexPai has a Qualcomm Snapdragon 8 processor, a Super AMOLED screen, and 1920 x 1440 resolution with an expanded screen. The RAM memory is 8 GB and the memory is 256 GB. FlexPai also has two rooms: one 20 MP and another 16 MP. The battery has a capacity of 3,800 mAh, and Royole claims that deliveries will start in December.
It seems, however, that the launch model is located many miles from the point of view of quality from the Samsung or Apple series, but it is still the first real device for assembly, not a concept or prototype.
It will also be interesting to see what the life of the new screens will be like. Royole officials say their screen can withstand 200,000 bends before it degrades.
What does this mean for application developers
Developers will have to reprogram their applications if they want to fully use the folded display.
The fact that today's event is devoted to gathering opinions, including from application developers, is probably not ready to be tried anymore.
Instead, after presenting the device interface, along with the first detailed images of the phone, the information should be enough for programmers to start optimizing the application.
FlexiPai from Royole launches a modified version of Android 9.0, called the Water OS, which has been adapted to support various phone display sizes.
Royole says he's still working on software updates, and from what I've seen in smartphone reviews, it's still working. For example, when you rotate the screen or climb onto it, there is a significant delay in the response. The version also has obvious bugs, such as some widgets that do not fit the screen size.
