As expected, Samsung announced the Galaxy Note 4, and the display is indeed a QHD (2560x1440) Super AMOLED panel. The exciting news (which I did not expect) is the Galaxy Note 4 Edge - the curved edge variant!
So first of all - you can see the Galaxy Note 4 Edge above. It sports a 5.6" QHD (2560x1440) display, with an extra 160-pixels on the right edge (Samsung calls this QHD+). The bent edge (besides being unique and probably very cool) can show notifications, application icons or simply controls when you want the full screen to show a video for example.
Besides the different display, both phones share pretty much the same specifications. Android 4.4, a 2.7 Ghz Quad-Core CPU (1.9 Ghz Octa-Core in some markets for the Note 4), 3 GB of RAM, 16 mp camera (with Smart OiS), S-Pen, Heart-rate sensor, UV sensor, finger scanner, 32 GB of on board memory plus a micro SD slot (the Edge has a 64Gb model) and a 3,220 mAh battery (3,000 on the Edge).
Both phones has a premium metal (aluminum) frame (similar to the Galaxy Alpha). This seems to be Samsung's new design for high-end phones.
Samsung will release both phones in October 2014. The Galaxy Note 4 Edge will probably cost more than the regular Note 4, but we do not know the price for these phones yet.
The Note 4 Edge will be released in October, and will probably cost more than the regular Note 4.
The Note 4 Edge is very similar to the YOUM AMOLED prototype unveiled in January 2013 (yes, it's over a year and half since!) - but Samsung does not refer to the new display as a YOUM display. Seems that Samsung abandoned that brand and simply calls this a Super AMOLED display (that happens to be bent around the edge).
