There was a time when the popularity of foldable phones is so much that people use to pay premium price for such kind of phones. But as the time passes and with the advent of platforms such as android and iOS, the popularity of such phones reduced considerably. They are now replaced with what I call fancy bricks.
Samsung is going to break this habit of so many years by launching Galaxy X foldable smartphone in February, 2019. So people who are waiting eagerly to try something new, please wait till February, 2019.
Galaxy X will feature never seen before 3 OLED screens measuring 3.5 inches. 2 of these screens will be concatenated to form a big 7 inch display and one will be at back. Specs are not yet revealed.
