Along with the Galaxy Note 4, Samsung also announced a separate version of the device that packs a display that curves over one side of the device.
The curved display on the side of the device acts independently from the main 5.7inch Quad HD Super AMOLED display. This allows users to launch apps and access media controls without interrupting full screen viewing. Users can also view information whilst the cover is closed over the device. The curved area also serves as a secondary notification area so you can get notifications there while watching videos.
The insides of the Galaxy Note Edge are pretty much the same has the Galaxy Note 4, head over to the post the get all of the information.
