Well this is a bolt from the blue. It appears that Samsung are on schedule to launch a smartphone with a curved screen by the end of the year.
The momentous news was dropped in the middle of the global launch of the Samsung Galaxy Note 3 today and apparently it will land some time in Q4.
Samsung paraded a prototype flexible screen called the Youm back at CES in January (see above video), and it seems that the new version will be based on that design.
According to Park Sang-jin, CEO of Samsung SDI, the new device will use a similar OLED panel and will be curve-shaped, but not completely flexible. Interestingly that prototype was able to display notifications along the side.
