Yesterday we reported that Samsung started mass producing plastic-based 5.7" FHD flexible OLED panels, and today the company announced the first device to use them - the Galaxy Round smartphone. This is an Android 4.3 smartphone similar to the Galaxy Note 3, with the major feature being the curved (400 mm curvature radius) flexible display (samsung simply refers to it as a flexible Super AMOLED, strangely they are not using the YOUM brand).

The Galaxy Round includes all sorts of user interface tweaks to take advantage of the curved screen, for example the so-called Roll-Effect that enables user to check information such as date, time, missed call and battery easily when home screen is off (see video below) and the "Gravity Effect" for creating visual interaction with the screen by tilting the device.
