Samsung introduced its first folding phone, which the company called "the future of mobile display technology".
The new device has a full touch screen and then can be detected to reveal what the company calls Infinity Flex, another, folding 7.3 inch AMOLED display that can simultaneously display up to three applications.
The Korean company briefly showed the device on stage at its developer conference in San Francisco, but it stopped confirming the name of the device or when it was released to the public.
Samsung is Justin Denison, however, said he would be "ready to begin mass production in the coming months," and called the new display technology "the biggest leap forward in the last decade."
Mr Denison said that the folding phone will use the feature of the continuity so that any application that is used on a smaller screen of the phone will automatically run in the same place after a larger tablet screen has been developed.
Google, the Android operating system manufacturer that Samsung uses on its smartphones and tablets, appeared with Samsung at the event to confirm that it will update its support software to a new type of device.

Samsung's president of mobile telephony from DJ Koh said: "The folding screen is the foundation for a new kind of mobile experience.
"We are excited to work with developers on this new platform to create new value for our customers. We can not wait to see where technology and collaboration lead us."
The development keynote was also used to detect a new version of Samsung's mobile interface, called One UI.
