Samsung Galaxy Note 3 with flexible display is not a rumor any more. One of the Samsung executive confirmed this update and stressed that intact Samsung will launch the device as early as next month.
This news is reported by an Asian daily who contacted the Samsung executive directly. Samsung and LG both are working on their flexible display solutions. So a Note 3 with flexible display is not a big surprise. But flexible displays are not yet ready for mass production, so Samsung will produce a handful of Note 3 with flexible screens.
The only down side of this variant of Note 3 is that it will cost a lot more when compared to AMOLED sported Note 3.
Samsung is also working on cheaper variant of Galaxy Note 3 with LCD screen and less powerful camera.
