Having inherited the “family” design and electronic pen S Pen, planshetofon Samsung Galaxy Note 4 got a huge screen with a resolution of Quad HD and – for the first time – a metal enclosure. What else is interesting, one of the most advanced “spades” on the market, find out Vesti.Haytek.
It would not be an exaggeration to say that the Galaxy Note 4 among planshetofonov – “star” of the first magnitude. Fulfilling the mission of technological flagship, the device has absorbed most of today’s top mobile technologies. Note that the family of Galaxy Note, in addition to a business audience is positioned as the creative professionals that require, in particular, the ability to draw or photo editing skills and texts. It’s no secret the fact that smartphones with big screens often jokingly referred to as “spades”. So, in the Galaxy Note 4 seems to have everything to easily rake debris everyday tasks. Thus, we estimate the main features of the new device.

Design and Ergonomics
New in the family of Galaxy Note has retained a recognizable appearance, despite the new trends in the design of the company’s smartphones.
In particular, it concerns shaped metal frame with a slight bend, passing around the perimeter of the device, which ensures its conformation necessary rigor and style. However, unlike, for example, from the Galaxy Alpha, the frame is painted now in the main body color, which can be black, white, bronze or pink. The presence of metal speak only silver bevel on the edges of the frame. As for the size of the new planshetofona, then, compared with the Galaxy Note 3, they have changed only slightly – 153,5h78,6h8,5 mm against 151,2h79,2h8,3 mm. This is easily explained at least in that the device screen size remained unchanged (5.7 inches). But weight has increased by 8 grams (176 g vs. 168 g). Incidentally, we note that in planshetofone not attended to dust and moisture protection devices, such as in the case of the flagship Galaxy S5 (IP67).
A faint “bulge” of the screen, to round off the edges of the body, due to the use in Galaxy Note 3 safety glass 2,5D Gorilla Glass 3 from the company Corning. Incidentally, the display covers the front surface of 74.39% planshetofona, though, for example, this ratio Galaxy S5 is only 69,76%.
At the top of the front panel provided holes for the LED charge / events lattice” conversational “speaker, the front camera lens as well as proximity sensors and lighting.
In an oval mechanical button “Home” / “Home Screen” below the display, as in the Galaxy S5, added a fingerprint scanner, which was not in the previous model family. Dedicated touch buttons “Recent Apps” and “Back” can not be seen without light, the work of which is configured in a special menu item.
A thin metal power button / lock still holds the right edge of the unit,
and the left – the same metal volume rocker.
At the bottom there is a connector microUSB, two holes for microphones,
as well as the case for the electronic pen S Pen,
and at the top – one more hole for the third microphone, 3.5mm audiogarnitury and peephole IR port.
In a removable back cover is preserved stylization” under the skin “, while drawing seems to have become more prominent. The material used here is pleasant to the touch soft-touch plastic. But emphasizing texture decorative “line” on a path cover had disappeared. The back panel offers access to the battery with a built-in antenna NFC, and microSD card slot and a microSIM. At the same time, to install the latest must first remove the battery.
in the upper portion of the cover provided two openings for the main camera lens, and for the LED flash unit and multifunction sensor (heart rate, blood oxygen concentration, and ultraviolet radiation). In the lower part of the grille moved “multimedia” speaker, which Galaxy Note 3 was placed on the bottom. On the left side of the cover (rear view) made a small gap, through which it is quite simply removed.
Covering the back cover not only provides pleasant tactile sensation, but with edges and protrusions metal frame protects the unit from slipping out hands. In addition, the settings are special tools for easy management planshetofonom one hand.
screen, camera, sound
Display, of course, the basic hardware “feature” Galaxy Note 4. Experts from the company DisplayMate, which specializes in testing screens even noted this new element planshetofona as the best on the market. On Super AMOLED-matrix with a diagonal of 5.7 inches provides a resolution of 2560×1440 pixels (Quad HD, 2K). Compared with the screen Galaxy Note 3 (Full HD, 1920×1080) the number of dots increased by 1.8 times, and the density of pixels per inch increase, respectively, in a 386 ppi to 515 ppi. Whereby the display is formed very clear picture, rich colors and wide viewing angles. Special role does not play even used a scheme with two sub-pixels PenTile RGBG, which “sin” all Super AMOLED-display.
In order to correct the color, which may seem too” acid “in the settings screen is available four profiles:” Main “,” Photo AMOLED “,” Movie AMOLED “and” Adaptive Display “. In the latter case, the automatic optimization of the color range, saturation and sharpness for only a few applications, but this does not guarantee compatibility with third-party applications. Planshetofonom can be operated with gloves on, if you include the option to increase the sensitivity of the touch screen layer settings.
If you have a good anti-reflective properties of the screen is pretty decent margin of brightness that makes it comfortable to use it, including sunlight. The brightness level can be adjusted manually or use auto-tuning it to a light sensor. Capacitive screen Galaxy Note 4 supports multi-touch, and the programs and AntTuTu Tester MultiTouch Tester confirmed that detects up to ten simultaneous keystrokes. The manufacturer claims that the response time of the matrix is one-millionth of a second. The advantages of the screen should also be considered a very good oleophobic coating.
The main camera planshetofona received photomodule Sony IMX240 Exmor RS, where 16-megapixel sensor is located on the 1 / 2.6-inch BSI-matrix and the aperture 31 mm lens is f / 2.2. Not forgotten as autofocus and LED flash. “Smart” optical image stabilization system (Smart OIS) with a small vibration compensates the jitter smartphone, avoiding the “shake”, and automatically extends the exposure time under low light conditions. Maximum image resolution is 5312h2988 points (16 MP) at a ratio of 16: 9 and 3984h2988 points (12 MP) at the aspect ratio of 4: 3. Examples of the photo you can see here (Dropbox).
At the front camera turned out to be an impressive 3.7-megapixel sensor with an aperture of f / 1.9, and, quite apart from the expected “Self-Portrait”, supported by the panoramic shooting mode (viewing angle of 120 degrees) for group “crossbow”. Get a self, as usual, can be adjusted to decorate and improve. The maximum resolution for “sebyashek” here 2560h1440 points (3.7 MP, 16: 9), and the classical aspect ratio – 1920×1440 pixels (2.8 MP, 4: 3).
The organization and design of the interface in the application “Camera” is virtually identical to that used for example in a smartphone Galaxy Alpha. Desired labels frequently used settings can be easily installed on the main screen. In addition to “Auto”, here and in the presence of more than a dozen specialized modes, including “Self-Portrait”, “selective focus” (after the frame is made, you can choose a proximal and a distal or panoramic focus) and “Panorama”.
The main camera can shoot 4K-, or UHD-video (3840h2160 points, 16: 9) at 30 fps. And the front camera the best record at the same frame rate is obtained only as Quad HD (2560h1440 points, 16: 9). All content is retained in the container file MP4 (AVC – video, AAC – audio).
The sound of the “multimedia” speaker Galaxy Note 4 is not very loud, but nice. He almost muted, even when the smartphone screen is up (but on a solid surface, of course). Playing fairly clean, with tangible bass and treble.
Three microphones (two on the bottom and one on top of the phone) successfully cope not only with noise reduction. Thus, in the application “Voice Recorder” added another three recording modes. In “Interview” record sounds is carried out from two directions (from different ends planshetofona). On “Meeting / Meeting” device is able to distinguish up to 8 audio sources, with the completion of recording some of them can be excluded. A “Voice Memo” allows you to immediately convert the recorded voice into text.
Filling performance
Currently, the Galaxy Note 4 – one of the most powerful smartphone in the world. His model SM-N910C is made based on the latest SoC production Samsung – Exynos 7 Octa 5433. Recall that planshetofon previous generation Galaxy Note 3 hides under its hood a crystal Exynos 5 Octa 5420, created with the less restrictive design rules (28 nm against 20 nm), which affects its performance and power.
The architecture of the chip Exynos Octa 7 5433 – big.LITTLE GTS (Global Task Scheduling) – also includes eight processor cores, four of which are high, and the remaining four – energy efficient. However, at the same time, place cores ARM Cortex-A15 and ARM Cortex-A7 took ARM Cortex-A57 and ARM Cortex-A53, respectively, operating at a maximum frequency of 1.9 GHz and 1.3 GHz, respectively. The main difference between the new kernels is that they are based on a 64-bit architecture ARMv8, of course, with full support for existing 32-bit applications. Performance, they are said to have about 50% higher than their predecessors. Recall that support heterogeneous multiprotsessinga allows you to use all the cores of the crystal at the same time. For graphics processing chip has a special accelerator ARM Mali-T760 MP6. Six powerful execution units operating at frequencies up to 700 MHz, enabled him to gain a reputation as one of the fastest in its class. The basic configuration of the device complements the 3 GB of RAM. 8-core processor with graphics accelerator cope with the high resolution screen without any problems.
In the synthetic tests AnTuTu Benchmark 5.2.0 new planshetofon looked the most impeccably. Received the title of “monster” and typing 49839 “virtual parrot,” he said, in particular, did not leave any chance, for example, the flagship HTC One (M8). Note that the Galaxy Note 3 could expect in this test of about 35 thousand “virtual birds”.
In the benchmarks Vellamo 3.0 with multi-core tests (MultiCore) Galaxy Note 4 in the lead with a score of 1883 points, but he was only the second in the evaluation of” horsepower “on the CPU test (Metal ), giving “killer flagships” OnePlus One (1570 vs. 1653).
On the visual test Epic Citadel at variable settings, High Performance and High Quality (performance at the expense of quality and vice versa), the average frame rate to permit 2560h1440 points differed in importance only after the decimal point – 58.7 and 58,5 fps. Changing the settings on Ultra High Quality predictably reduced the value of this parameter (up to 46,8 fps).
It is confidently made planshetofon and universal gaming benchmarks 3DMark, which results Galaxy Note 3 on tests Ice Storm Extreme, simply read off scale.
Of the 32 GB of internal memory available approximately 24.4 GB, which can be extended for another 128 GB with cards microSDXC. In addition, external flash drives can be easily connected via OTG USB-cable.
The flagship suite includes communications planshetofona seems everything you need: 2-band Wi-Fi-module 802.11 a / b / g / n / ac (2,4 and 5 GHz), Bluetooth 4.1, ANT +, Infrared, NFC. Furthermore, Galaxy Note 4 may operate in Russian mobile networks LTE (Cat. 4). Incidentally, we note that the use of Bluetooth 4.1 reduces interference from LTE in adjacent frequency bands.
For the positioning and navigation systems can be used satellites GPS, GLONASS and Beidou. There is also support A-GPS. This, in particular, by the testimony of the test program AndroiTS GPS Test.
Compared to last year’s version, the capacity of lithium-ion battery in the Galaxy Note 4 rose very slightly from 3200 mAh to 3220 mAh h. At the same time, for the Galaxy Note 4 manufacturer stated while surfing the Internet (3G / LTE / Wi-Fi) – 11, 10 and 13 hours, respectively. But for video playback will be limited to 12 hours. Thus, our test video in MP4 format and Full HD-quality at full brightness spun continuously for just over 9 hours, which, generally speaking, very good.
On battery test AnTuTu Tester planshetofon earned 6872 points, ahead on points 6-inch Lenovo Vibe Z2 Pro ( 4837) with the same Quad HD-resolution and rather capacious lithium-polymer battery 4000 mAh. In practice, the autonomy of the new planshetofona is approximately at the same level as that of the Galaxy Note 3. Fast Charge allows you to fill the battery from zero to 50% in about half an hour, however, this would require a special 2-mode (5 V, 2 A and 9; 1.67 A) charger, or bundled, or meet the specifications Qualcomm Quick Charge 2.0.
Have not gone away traditional for Samsung power saving modes, including extreme that turns the device into a simple” dialer “. Typical conventional measures of energy saving – a limit on the baseline data and / or performance, as well as the rejection of a color picture interface.
Software
Over the latest version of Android 4.4.4 (KitKat) in the Galaxy Note 3 uses the familiar proprietary shell from Samsung – TouchWiz. Compared with that used in the Galaxy S5, it has changed little, although some differences still there. And most important of them is the multitasking. Recall that in 2012 in the Galaxy Note II offered the ability to simultaneously run two programs, dividing the space between the big screen.
Function Multi Window in the Galaxy Note 4 makes good use of multi-tasking device, choosing the most convenient way to access applications – in full screen, split into multiple windows or pop-up windows. The size and location of the windows on the screen, which, incidentally, may overlap each other, it is easy to change. In the collapsed state on top of everything will hang round icons denoting application windows. Translation of any program in the mode of reduced window is as simple gesture (swipe your finger from the top of the screen down on a diagonal).
By the way, a private news application forms are no longer My Magazine (as in the Galaxy Note 3), and Briefing.
Among the pre-installed software on the Galaxy Note 4 worth noting customers popular services, including including such as Evernote, Facebook, Instagram and WhatsApp.
