Samsung Electronics has announced the release date of its upcoming device dubbed as Galaxy Note 4 but has been keeping mum on it features. However, several reports have revealed every bit of the device from software to design to hardware.

The South Korean electronics giant has revealed that the second edition of its launch event, Samsung Unpacked 2014 will be held simultaneously in Berlin, Beijing and New York City on 3 September. The company usually unveils the Note series at IFA Berlin but has advanced by a couple of days this time.

Samsung Galaxy Note series has been a big hit among gadget lovers and it is natural that expectations are huge on the upcoming device. Going by the reports, Galaxy Note 4 may see some major upgrades over its predecessor and some of the most striking features expected in the new device are as follows:

1) Design: Samsung has not brought major change to its Note series so far but the upcoming device may come with a different look. According to the Korea Times, Samsung will release two models of Galaxy Note 4 - one with a curved OLED display and the other with a flat OLED display. Executive vice president of Samsung's mobile business, Lee Younghee told Wall Street Journal that the company is thinking of a flexible display for the next generation device.

2) Operating System: According to reports, Galaxy Note 4 might runs on either Android 4.4.3 KitKat OS or Android Lollypop. However, it seems unlikely that Android Lollypop will be seen in the device, as Google is reportedly planning to introduce the new software in its upcoming smartphone dubbed as Nexus which is due in October. In the meantime, one can't rule out that the software won't come with the yet-to-be released software. At least the Samsung device may get the update as soon as it is released.

3) Irris Scanner: Rumors were rife that Samsung might introduce retina scanner in its recently released Galaxy S5 but it never happened. Now, the Samsung Exynos Twitter account has sparked off speculations that retina scanner could be introduced in the upcoming device by tweeting: "Security can be improved using features unique to us. That's what we envision. What would you use?"

4) Display: Users may experience great picture quality in the next-generation Note series, as it may 2k resolution. Reports suggest that the device will a sport a 5.7-inch super Amoled display with a 2560x1440 resolution (500+ppi) compared to 1080 x 1920 pixels, 5.7-inch (386 ppi pixel density) seen in Note 3.

Moreover, Galaxy Note 4 may come with several upgrades over its predecessor, Note 3. Samsung may launch two versions of Galaxy Note 4, one to be powered by Qualcomm Snapdragon 805, and the other with Exynos 5433 8 Core processor, according to AnTuTu benchmark listings. The new device might have S-Pen stylus with updated gestures and air command, and a patent application filed by Samsung obtained by Galaxy Club has revealed that the S Pen might be powered by ultrasound technology.

While reports by Samsung4Note website and AnTuTu benchmark listings suggested that the Galaxy Note 4 may have a 16MP camera, G4Games (via ETNews) reported that camera pixel of the new device might be reduced to 12MP camera with OIS. It is not sure whether Samsung will upgrade the camera of its upcoming device or not. The device will come packed with a 3GB LPDDR3 RAM, which is seen in its predecessor, Note 3.
