With just a few days left for the UNPACKED IFA event in Berlin, Samsung continues the marketing campaign for its upcoming flagship smartphone, Galaxy Note 4, with an emphasis on the S-Pen stylus functionality and its revolutionary features via a new teaser video.

The Galaxy Note 4 is undoubtedly the hottest product which is slated to be launched at IFA on 3 September with stiff competition from the likes of Sony, LG, Apple and Motorola.

Sony's Xperia Z3, Apple iPhone 6 and Moto X+1 are the biggest rivals for the highly-anticipated fourth-gen phablet in the Galaxy Note series, while Samsung claims that its revolutionary S-Pen stylus is capable of substituting all existing stylus pens in the market.

Prospective Galaxy Note 4 buyers are invited to check out Samsung's live streaming broadcast of the UNPACKED event via its official YouTube channel at 15:00 CEST on 3 September.

As far as the specifications are concerned, the Galaxy Note 4 will reportedly ship in two variants: a Qualcomm Snapdragon 805 or Exynos 5 Octa powered handset.

Among other key speculated features, the Note 4 will include a 5.7in Quad HD display, 16MP rear camera and 3.7MP camera sensor with video recording capability in WQHD (2560 x 1440) resolution.
