    History tour


    I already wrote about this company in the framework of Brand History here: Samsung Electronics History: From dried fish to high technology . And now I propose to see how the Galaxy Note smartphones have changed over time.

    Galaxy Note

    In 2011, the Samsung Galaxy Note appeared. The 5.29-inch display is its main distinguishing feature. The display resolution is 800x1280, which is now not enough for such a screen. The smartphone runs on a dual-core Samsung Exynos 4210, 1400 MHz processor.

    Bonus - stylus.

    Galaxy Note II

    In October of the following year, 2012, a successor appeared on sale: Galaxy Note II. The display has grown to 5.55 inches. The resolution of the SuperAMOLED display is 1280 × 720 pixels. Cores were also added - Note II is built on the basis of the quad-core Exynos 4412, 1600 MHz.

    Galaxy Note III

    The next model, Note III, the display has grown again - up to 5.7 inches. The resolution is 1920 × 1080, and the processor is either the eight-core Exynos 5 Octa 5420 in the version with 3G, or the Snapdragon 800 quad core 2.3ghz in the LTE version. Again there is support for the S-Pen stylus, as in previous models.

    Design


    Rumor has it that the body will be made of an alloy of magnesium and aluminum. Judging by this photograph, the authenticity of which has some doubts, the back cover will be covered with textured leather, the front part of the case will be made of glass and plastic, and the side faces will receive a new design. The design of the front part is slightly different from Note III.

    According to Upleaks, the smartphone will be presented in five color options: white, pink, gold, black and blue.

    CPU


    As with the third Note, the new phablet will have two processor options. By the way, their results are already available in Antutu Benchmark.

    The first option is an Exynos 5433 processor. These are four 64-bit Cortex-A57 cores and four Cortex-A53. The second option is Qualcomm Snapdragon 805, i.e. 4 32-bit Krait 450 cores and Adreno 420 graphics.

    Display


    The display resolution of the new Note 4 will match the 5.75-inch diagonal: these are 2560x1440 Quad HD pixels. Of the phones that already have this resolution, there are only the LG G3 and Lenovo Vibe Z2 Pro.

    There are a couple more models with Quad HD display , but in Russia they are not common - these are Vivo and Oppo, owned by BBK.

    Curved display?


    Or will the display be similar to this one, curved at the ends of the smartphone?

    The company introduced this development last year at CES 2013 - a flexible display.



    Camera


    The main camera of 16 megapixels will allow you to shoot video with a resolution of 3840 by 2160. In Note III was 13 megapixels, and in the first smartphone of the line - only 8 megapixels. Such changes have occurred over 3 years. The main camera is equipped with a Sony IMX240 sensor. The same sensor was used in the LTE version of the Galaxy S5 for the Korean market.

    What about the front camera - for the last few years the company often used a 2.1-megapixel camera, this time changed this tradition and installed 3.7 megapixels, which allows you to make selfies with a resolution of 2560x1440.

    Perhaps Note 4 uses Side Touch technology, which they did not add to the Galaxy S5 at the beginning of the year. The technology is as follows: instead of a physical button for a photograph located at the bottom of the right end of the case, you just need to tap on this part of it.

    Retina scanner


    Before the release of the Galaxy S5, there were rumors about the possible use of a retina scanner module in it. And the other day, the Exynos-division of the company published this image: on it we see a rather large smartphone, which, perhaps, is Note 4. So, maybe, protection in the form of an iris scanner will be used in Note 4.

    Accessories


    Cover

    This item I included in the article only because of one announced accessory: because of the cover, which will help to identify obstacles using ultrasound. I hope this technology can be used to improve the lives of visually impaired people. If this succeeds, then I will definitely write about applications and methods of application in the continuation of this article .

    According to this publication, the cover consists of an ultrasonic sensor that detects nearby objects in front of you and provides feedback. Users can also change the range of ultrasonic signals and choose one of three levels: short, medium and long. It is only with an increase in the range of ultrasonic signals that the area covered by them narrows.

    Perhaps this is the most useful accessory in the history of the company. If, again, they find proper use for him.

    S-pen

    Have you ever noticed that you cannot write with your hands? I'm so used to the keyboard that I even sign it with difficulty. Samsung throughout the Galaxy Note line is campaigning for a stylus called the S-Pen. Very inspiring video, by the way.

    That's just in this video, Note III is demonstrated, so it is not yet known how the new smartphone will look.



    Perhaps the S-Pen stylus will be ultrasonic: four sensors along the edges of the display will allow you to work with the stylus without touching the screen.

    While writing, I came across this video. Apparently, on it we see exactly the new Galaxy Note 4, but this information has not yet been confirmed. youtu.be/txa2wUO6fvg



    Total


    There are a lot of rumors about the new product, and you will have to wait until next Wednesday to find out what share of truth is in them: the Samsung smartphone will present at the IFA exhibition on September 3. Broadcast from the presentation will certainly be available on the Samsung website.
