After months of speculations, Samsung finally unveiled the much anticipated Galaxy Note 4 and the curved screen based Note Edge in Berlin today, just a couple of days ahead of IFA (Internationale Funkausstellung Berlin) 2014 (5-10 September).

Galaxy Note 4 keeps the same 5.7-inch screen size seen in its predecessor but its resolution has gone up a couple of notches this time. It boasts a QHD (aka 2K) 2560x1440p resolution display, which is equivalent to 515 plus ppi (Pixels Per Inch) density.

Under the hood, it boasts the company's inhouse built Exynos 5433 series Octa-core CPU (1.9GHz quad-core + 1.3GHz quad-core +ARM Mali T760 GPU)/ 2.7GHz Snapdragon 805 quad-core processor) paired with Adreno 420 graphics engine. It is backed by 3GB RAM, 32GB inbuilt memory (expandable up 64GB) and a 3220 mAh battery.

"The Galaxy Note series signaled extraordinary innovation within the technology industry. Its larger screen size and iconic S Pen technology launched a new standard in smartphone culture," pointed out JK Shin, CEO and Head of IT & Mobile Communication at Samsung Electronics.

"With the introduction of the Galaxy Note series, we brought the age-old culture of the pen and notepad into the digital world. The new Galaxy Note 4 introduces the most refined Note experience to-date by combining all the latest technology that users expect from the Galaxy series," he added.

On the camera front, a 16.0-megapixel camera with auto-focus and smart OIS (Optimized Image Stabilization) and a 3.7-megapixel snapper with F1.0 aperture, wide selfie feature and many more value-added photography enriching apps (scroll down for detailed specifications).

Galaxy Note Edge, on the other hand, packs pretty much the same internal hardware specifications, sans the display. It boasts a 5.6-inch (quad HD Plus resolution) unique curved Edge screen, which provides quick access to frequently used apps, alerts and device functionality - even when the cover is closed. Users just have to swipe their thumb to navigate on the edge screen. Users can also receive notifications directly on the Edge Screen while watching videos, without getting disturbed.
