The unfolded screen of the upcoming phone is bigger than Samsung's biggest smartphone, the Note9, which is 6.4 inches, and the iPhone XS Max at 6.5 inches.
At first glance, one of the most noticeable improvements with the Galaxy J4 Core compared to the J2 Core is the display. They've been teasing a folding model for about five years now, and here it is. Foldable devicesOLED display technology is now making inroads in the TV market but it also has the potential to change how we use our handheld devices.
A Samsung insider we know by the Twitter and Weibo handle of Ice Universe said that he doesn't expect to see cameras behind the displays of smartphones until 2020.
Samsung Electronics unveiled its anticipated foldable phone in San Francisco on Wednesday, urging Android developers to start writing apps for it.
Samsung, which makes iPhone OLED displays, will get us even closer if that Infinity-O screen prediction turns out to be accurate.
"The foldable display lays the foundation for a new kind of mobile experience", said Koh Dong-jin, president and CEO of the IT and mobile communications division at Samsung.
Dave Burke, vice president of engineering at Google, said at the Android Developer Summit that Google is "enhancing Android to take advantage of this new form factor with as little work as necessary". Samsung released its first Android Go phone earlier this year in the form of the Galaxy J2 Core, and just a few months later, we have another entry with the J4 Core.
The Verge's reporter Nick Statt said that when folded, the phone was "bulky" and "feels miles away in quality" from a high-end smartphone.
Developer Joshua Clark, who was at the conference, said Samsung needs to sell the technology to its competitors for the product to be widely adopted.
