Samsung has released more than expected fold phones and has called on Android developers to start writing apps for new devices.
Korean high-tech companies have to make perfect folding phones to reverse the loss of profit of the mobile division and to restore the brand's lost cassette.
Foldable phones promise a small tablet screen for small size devices.
Janin Denison, senior vice president of mobile product marketing at San Francisco, unveiled a prototype with a screen size of 18.5 cm (7.3 inches) diagonally.
It looked like a thick phone with two folds, but Samsung did not give the media or developer a chance to touch the device or get a closer look.
Dave Burke, Google's vice president of engineering for Android's software platform, said in a conference in California that he plans to showcase new Android-based devices early next year.
"We look forward to a collapsible product from several Android manufacturers."
Glen Murphy, the chief executive of Google's Android UX, also took the stage with Samsung and said that Google will work with the developer community to bring more features to the phone.
Samsung said it will be able to mass-produce in the coming months.
Joshua Clark, a developer who attended the conference, said Samsung Electronics should sell its technology to competitors and adopt it widespreadly.
"I think we need only two companies, and then we'll go bankrupt," Clark said. "And the fact that Google has come to the stage says a lot, and it gives me a lot of confidence when it comes to integrating with all apps."
Bob ODonnell, an analyst at Technalysis Research, said the bendable screen provided a wah-pack, but a shopper might not like the thickness or price tag of a folded phone.
O'Donnell said, "They just have to prove that they are more than just special effects." But it's wise to open up early for developers to experience a lot of things. "
Samsung Electronics is one of the few developers to develop foldable mobile phones. Huawei plans to launch a fifth-generation smartphone with a folding screen in mid-2019.
However, Samsung Electronics and Huawei last week were hit by Chinese display maker Royole, which released a larger screen folding Android phone last week, priced at $ 1,300. Royole said he would begin filling orders at the end of December.
