More features of Samsung's upcoming flagship smartphone dubbed as Galaxy Note 4 have started surfacing with the release date drawing nearer, and it looks like it will be another great device like its predecessors. However, there are a few features that could disappoint fans when the smartphone hits the stores in September.

Many followers and fans of Samsung Electronics, which popularized big screen handsets, must be so used to the company's trend of ever increasing screen size of its flagship devices that they may not be happy with anything small or constant.

The South Korean electronics giant usually increases the screen size of its new Note series device by .2 inches every time it comes up with a new device. It introduced Galaxy Note phablet with a 5.3-inch display before increasing the screen size to 5.5-inch in Note 2 and 5.7-inch in Note 3. Many must be expecting the smartphone maker to increase screen size of Note 4 too by at least .2 inches, but it may not happen if the latest reports have anything to go by.

Samsung Galaxy Note 4 will have a 5.7-inch screen size, which is the same as its predecessor Note 3, according to reports. Some argue that the flagship device should have a 5.9-inch or 6-inch display while others say that the company was right in keeping the screen size constant as handsets bigger than 5.7-inch will be too big to hold.

The good news is that the upcoming device may have a 2560x1440 resolution screen with 500+ppi as against Note 3's 1080x1920 pixels with 386 ppi pixel density.

It is also reported that the much-awaited Galaxy Note 4 may come with a 12MP camera but with optical image stabilization (OIS), according to a report by G4Games (via ETNews). The move may surprise many as Note 3 has a 13MP camera with autofocus and LED flash. However, Samsung4Note website reported that Note 4 may have a 16MP rear camera with ISOCELL technology, 4K video recording and a 2MP front camera with 1080p video recording.

While prospective buyers of Note 4 may expect more memory, reports suggested that it will come with a 3GB LPDDR3 RAM, the same storage seem in its predecessor, Note 3.

Samsung may not upgrade some features seen in its Galaxy Note 3, but overall, the upcoming flagship device may not fail to impress gadget lovers like its predecessors.

Samsung may release two versions of Galaxy Note 4, one to be powered by Qualcomm Snapdragon 805 that features Krait 450 (300MHz-2457MHz) CPU and Adreno 420 GPU, and the other with Exynos 5433 8 Core processor that has ARM Mali-T760 GPU. It will run on either the recently released Android 4.4.3 KitKat OS or Android 4.5 Lollypop, which is expected to be seen in Google's Nexus 6, according to AnTuTu benchmark listings.

Two models of the device - one with a curved OLED display and the other with a flat OLED display – will be released, according to the Korea Times. 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. It is also reported that the phablet might have ultraviolet sensor, retina scanner and S-Pen stylus with updated gestures and air command that could be powered by ultrasound technology.

Galaxy Note 4 will be unveiled on 3 September and the invitation to the Unpacked event would be sent out in mid-August, according to a report by Android Geeks. The Korea Times also claimed that the device would be unveiled at the upcoming annual IFA trade fair in Berlin, Germany to be held between 5-10 September.
