Samsung Foldable Phone: The ‘Galaxy X’ Details

By Noah Long ● Updated November 13, 2018

Samsung has recently confirmed that it is releasing a foldable device — which is expected to be called the “Galaxy X” (or Galaxy F). In conjunction with Samsung’s announcement, Google also said that it is going to design software that supports foldable displays.

According to CNET, Samsung’s senior vice president of mobile marketing Justin Denison showcased the “Galaxy X” at the company’s fifth annual developers conference in San Francisco this week. The “Galaxy X” is a tablet when it is opened and it is a smartphone when it is closed. And the “Galaxy X” device is able to run three apps at the same time through the Multi Active Window feature.

Samsung’s “Galaxy X” is going to start being mass produced “in the coming months.” And the “Galaxy X” will feature Samsung’s new Infinity Flex Display. The Infinity Flex Display makes it possible for the device to be opened and closed repeatedly without degradation.

“The Infinity Flex Display represents an entirely new mobile platform,” said Denison via CNET. “We’ve been living in a world where the size of your screen can only be as large as the device itself. We’ve added a new dimension to help you browse, watch and multitask like never before.”

Samsung engineering director and the head of the system software group for the mobile business Jisun Park also said that the plan for “Galaxy X” is to have the battery last as long as current Galaxy smartphones. This would be very impressive because the display is quite a bit bigger than smartphones.

When the device is closed, you will see the Cover Display — which is when the device looks like a phone. The Cover Display is 4.58 inches, has a 21:9 aspect ratio, a screen density of 420 dpi, and a resolution of 840 x 1960. Once the device is folded, the Cover Display turns off and goes black. The Main Display — which is the bigger screen being viewed when the device is unfolded — is 7.3 inches, has a 4.2:3 aspect ratio, a screen density of 420 dpi, and a resolution of 1536 x 2152.

The “Galaxy X” device displayed on stage was not the final version of the product. It is most likely that the final version will have slimmer bezels.

Interestingly, a company called Rouyu Technology unveiled the Flexpai flexible smartphone last month. You can see what it looks like in this demo video:
