Samsung Galaxy Note7 Exynos - Specifications. Samsung Galaxy Note7 Exynos - Specifications All about smartphone samsung galaxy note 7

Samsung is another company with many flagships, which are again divided into spring and autumn. Why miss the opportunity to brag about your smartphones twice in a year? They don't miss out: Samsung Galaxy S7/S7 edge got their fair share of applause, attention and consumer interest, now it's time for the "big flagship" - Note 7, which is very close to the S7 in terms of characteristics, but larger in size, equipped with a stylus, modified software and - this year - a curved display.

Last year we already saw something similar, only without a curved display, under the name Note 5 - as you can see, Samsung is still unifying the lineup. Now it's more difficult to get confused: all new devices go under the same index. And they are very close in appearance - having received a curved display, Note 7 has become very similar to the S7 edge, only enlarged, with a stylus and USB Type-C - and the thickness of the case has remained unchanged.

The last fact would be happy, but I am writing this review after the well-known events with explosions of smartphones while charging and one of the largest recalls of devices in history - and it’s simply impossible to ignore this issue. Let's talk, however, about this, below, as well as about everything else.

⇡ Appearance and ergonomics

Samsung found its recipe for smartphone design back in the Galaxy S6 - and has been following it without retreat for a year and a half. Admittedly, the recipe is really good: take a thin case, sheathe it on both sides with tempered glass, put metal around the perimeter; place an oval button with a fingerprint scanner at the bottom of the front panel; if necessary, bend the edges of the case. In Note 7, this scheme has been brought to perfection - the edges of the glass are bent both on the front side and on the back, which makes the smartphone not only visually symmetrical, but, sorry for the stamp, it fits perfectly in your hand.

The latter is really impressive - when operating a 5.7-inch gadget, you do not experience serious discomfort, the sensations are quite comparable with those that were when working with the S7, and much more pleasant than when working with the edge. Minus the fact, of course, that you have to work without fail with two hands - you can, of course, activate a special "one-handed" mode, with a picture in a picture - but this, to be honest, is not very convenient. Note 7 is also difficult to fit into a pocket. Of course, pockets are different, but I tried a few - of all the smartphone bulged out at least slightly. However, all this is an inevitable feature of all large smartphones, which are also called the terrible word "phablet".

Samsung Galaxy Note 7 front panel. Above the screen: earpiece, front camera, light and proximity sensors, infrared iris recognition camera, and status indicator. Under the screen: Home button with a fingerprint scanner and touch keys "Back" and call the list of open applications

Unfortunately, the Note 7 only looks flawless in photos and shop windows. No, after purchase, it does not turn into a pumpkin, but the glass back panel collects fingerprints very easily. This is not too critical if you have, as in our case, the black version. If you have blue or silver - prepare your rags, gentlemen and ladies. The olephobic coating helps to quickly erase traces, but does not protect the case from collecting them.

Both for the display and for the back panel, Gorilla Glass 5 is used, which theoretically should not react at all to the touch of keys or little things in your pocket. In practice, things don't work out so well. Probably, the glass can withstand falls from a small height, but it is scratched with a bang. In order for the back panel to be scratched, you didn’t even need to carry a smartphone with keys - just from time to time put it on surfaces that are not perfectly smooth. There is no loss of functionality, but it does not look great.

The layout and shape of the keys are identical to what we saw on the Galaxy S7, with two volume buttons on the left and a power button on the right. You need to get used to this, on almost all other Android smartphones they lie together on the right side. Under the display is a mechanical Home button with a built-in fingerprint scanner, with which you can unlock the device in one motion - this is just a fairly common solution, and very convenient to boot.

The Note 7 is the first Samsung smartphone and the first smartphone since the Lumia 950 to feature an integrated iris scanner.

The infrared sensor is located above the screen and can quite quickly recognize the owner, one has only to bring the device at a distance of 25-30 cm to the eyes. Another thing is that, unlike the fingerprint scanner, you must first press the power button and swipe the lock screen - and then also bring the smartphone in an unnatural position to your face. You also need to take off your glasses, contact lenses, carefully monitor the cleanliness of the sensor and endure for a long time when the device remembers the shape of your eyes: he personally remembered mine from the 19th (I thought) attempt - it took at least five rather dreary minutes. But to fake an iris, unlike a fingerprint, is much more difficult. However, there is always a verification PIN code - if you really want to, you can bypass such strict protection.

By the way, I will not write separately about the fingerprint scanner - they have reached such a level that they work equally fast in both expensive and cheap devices, and when you meet a scanner in a smartphone for 10 thousand (like Vernee Thor), you are not even surprised. In general, it is also here, and it works quickly, without failures.

The case, like the S7, is protected according to the IP68 standard (up to half an hour at a depth of one and a half meters) - you can not be afraid of splashes and accidental drowning in a sink, sea or somewhere else. Since Sony refused to release devices protected according to the same standard, this can be called Samsung's signature feature. In terms of body thickness, by the way, Note 7 is identical to the “regular” S7 and is two-tenths of a millimeter thicker than the S7 edge.

There was also the same small problem with the speaker. It is monophonic, located on the lower edge, and it is clearly audible when the smartphone is flat - but as soon as you pick it up, especially in landscape orientation, the tiny grille overlaps with your finger and it is no longer possible to hear something. You have to carefully choose a place for your finger and put it on the stylus hidden in the case.

⇡ Software,SPen

With the Note 7, Samsung went ahead and changed the name of its Android skin. Grace UX has replaced the long-standing TouchWiz. And at first glance it seems that, in addition to the name and settings menu, nothing has changed. This is a misleading impression - the changes, though not cardinal, but in small things make using the device much more comfortable.

First of all, after a relatively long use, you notice that the smartphone no longer devours energy in standby mode, like fire - oxygen. Leaving your Note 7 unplugged overnight won't leave it empty the next morning. On the contrary, a maximum of 5-7% will be lost, or even less. Another key problem of TouchWiz also disappeared - along with a bunch of pre-installed branded applications that had to be forcibly "demolished" (and some were completely impossible to remove). Now the required software is a minimum, everything you need can be downloaded on your own either from Google Play or from the Samsung application store. True, the first launch process with the need to log in first to a Google account, then to a Samsung account and sign up for a lot of different agreements still remained too long.

Part 1: getting to know the key innovations

Samsung did not wait a bit for the IFA 2016 exhibition and announced its new flagship Galaxy Note7 back in early August. And already on August 19, the novelty went on sale in some countries. And although Russia is not among them, we were able to get a smartphone and studied it in detail.

You can read about the key features of the novelty in our news, so we will not re-tell the facts voiced at the presentation here. However, before proceeding directly to getting acquainted with the device, let's think a little about the evolution of the Note line. Exactly five years ago, the first Samsung Galaxy Note was announced, and for quite a long time this line developed in parallel with the Galaxy S series. Moreover, Note devices gradually began to lose their main difference - a large display diagonal. More precisely, a diagonal of 5.5 ″ has ceased to be something unusual, and even Galaxy S devices have acquired screens of similar sizes.

Another signature quality of Note is the stylus included (and, accordingly, support for full-fledged work with it in a smartphone). Here, the manufacturer is already more clearly distinguishing between the two lines, and competitors are not particularly in a hurry to equip their flagships with styluses. However, if earlier you had to pay for the presence of a stylus with the dimensions of the device (after all, the Galaxy Note remained larger than the Galaxy S), now there is no need to talk about any significant difference.

Even more interesting is the situation with the curved screen. Technologists and Samsung fans remember that it was the smartphone of the Note line that was the first to receive a side-curving screen: it was called the Samsung Galaxy Note Edge, and there was a bend there only on one side (you can also recall the experimental Samsung Galaxy Round smartphone here, but it did not receive development). However, then the curved screen chip moved to the Galaxy S line, with S Edge devices getting a screen bend on both sides. In turn, the new Note was produced without a bend. And now the bend returns to Note. And, what's even more interesting, you can't buy Note7 without a curved screen. That is, in fact, Note7 does not replace its immediate predecessor in the line, but the Samsung Galaxy S7 Edge smartphone. More precisely, judging by the characteristics, it turns out to be in some way a modification of the S7 Edge with several additional features, most of which will probably migrate to the Galaxy S line in the future.

Based on the fact that Samsung abandoned the word Edge in the name of the novelty, it can be assumed that in the future the only version of the flagship will remain in the Galaxy S series - with a curved screen. And, accordingly, the difference between Note and S will be reduced to the presence of a stylus and, perhaps, a slight difference in display size (although here we can’t help but recall the Samsung Galaxy S6 Edge +, which had a 5.7″ display).

Let's take a look at the specifications of the Samsung Galaxy Note7.

*according to manufacturer's official data

The table clearly shows that the changes in Note7 compared to S7 Edge are minimal. Slightly larger display diagonal (with the same resolution and other parameters) and, accordingly, slightly larger dimensions, but less battery capacity. The novelty has twice as much built-in flash memory (this, by the way, can be an excuse for a higher price), and there is also an iris scanner that no one else has, and a USB Type-C connector instead of Micro-USB (this is no longer you will be surprised, but Samsung has it for the first time).

As for comparison with competitors, the situation here is ambiguous. Moto X Force loses in some ways, wins in some ways, while its key “chips” are completely different: a nylon coating on the back surface and impact resistance (but there is no moisture protection and an iris scanner).

Comparison with the iPhone 6S Plus does not seem to be effective at all, because a new iPhone will be released in September, and it would be more correct to compare it with it. Nevertheless, we could not but include the smartphone of the market leader in the table.

But let's move on to direct testing and understand the Note7 innovations in practice.

Equipment

The smartphone is sold in a black rectangular box.

The kit includes a charger with Quick Charge support (5V 2A in standard mode, 9V 1.67A in Quick Charge mode), USB Type-C to USB cable, SIM and memory card cradle ejector, OTG adapter for USB Type-C (for connecting external USB drives with a full-size plug), an adapter from USB Type-C to Micro-USB (for charging with a regular Micro-USB cable), information leaflets and brochures, and headphones in a separate plastic box and with an additional set of rubber ear pads.

The earbuds are the same as the ones on the Samsung Galaxy S7 Edge and S6 Edge+, and we can only be happy about that. They have a tangle-free flat wire, a very comfortable shape of the ear cushions, and most importantly, a really decent sound. Even deep basses are transmitted very worthily.

Overall, we can't help but note that Samsung really cares about its users and tries to include everything they need in the package. After all, the same adapters for the new USB Type-C connector will probably be needed, and looking for them is an extra problem. You will spend more time and money on the road to the store than the adapter itself costs.

Design

The appearance of the Samsung Galaxy Note7 is much closer to the S7 Edge than to the previous Note. In fact, if you don't compare the Note7 and S7 Edge head-to-head, it's quite possible to confuse them. The general appearance and style are the same. And, frankly, over the past six months since testing the S7 Edge, our opinion on this style has not changed. Note7 looks very nice and impressive. Like the S7 Edge, it's one of the most stylish smartphones out there today.

Almost the entire front panel is occupied by a screen that wraps effectively on both sides along the long sides. And this is not only delightful in itself, but also creates the illusion of a complete absence of a frame on the sides. In fact, of course, there is a frame, but its sidewalls are already quite thin, and thanks to the rounding of the screen, they seem quite insignificant. True, unlike the S7 Edge, the rounding here is slightly smaller, and the metal edges, on the contrary, are wider. In the photo below, the S7 Edge sits on top of the Note7, and the difference in bezel thickness is clearly visible.

Is it convenient or not? Our editor Andrei Vorobyov, who has been using the Samsung Galaxy S7 Edge as his main smartphone for half a year, thinks it's convenient. Here is his opinion.

There is a feeling that in Note7 the side frames have become flat and wide by reducing the curves on both the front and back sides. As a result, the device is more confident in the hand. In terms of functionality, there is no deterioration compared to the S7 Edge, because both smartphones have a bent edge not large enough to accommodate information. only on them (separately from the main screen and without climbing onto it, like the Samsung Galaxy Note Edge). Therefore, a wider or already bent part is not so important.

The above photos clearly show that the bend in Note7 is really less. And it is hardly possible to use it as a functional element, that is, to place any controls on it. But here the main thing remains: the very fact of the bend and the illusion of the absence of edges. Therefore, the device looks no worse, and it is more comfortable in the hand. Like the S7 Edge, the edges are made of metal (more precisely, this is a full-fledged chassis, and not just a edging), and the front and back sides are made of plexiglass. Very stylish, but, alas, quite marco - prints on the back side are collected instantly.

All faces, like its predecessor, are made of metal, buttons too. They are pressed with a pleasant elasticity. The layout of buttons and connectors is similar to the previous model. On the right is the power button, on the left are separate volume buttons. On the bottom edge there is a speaker, a USB Type-C connector with OTG support, a 3.5 mm headset jack and a built-in microphone hole. In our review of the S7 Edge, we lamented that Samsung, unlike its competitors, is not yet equipping its flagships with a USB Type-C connector. And now - there is nothing to complain about :)

Of course, in addition to the changed connector, the rear tip of the stylus is striking in the photo of the bottom face. In order to pull it out of the smartphone, just press a little. Just as easily the stylus is inserted and fixed in the smartphone. The manufacturer emphasizes that the stylus can write even when the smartphone and stylus are submerged in water. We did not make such risky experiments, but we admit that the overall impressions of the stylus are the best. He distinguishes the force of pressing, allows you to perform small strokes.

The upper edge of the smartphone contains a combined slot for a memory card and two Nano-SIM format SIM cards. You can use either two SIM cards at the same time, or one SIM card and one microSD memory card.

Compared to the S7 Edge, there is only one difference here: the microphone has been moved closer to the edge.

There will be three color options for sale: dazzling platinum (gold), titanium silver (metallic) and black diamond (black). We tested the titanium silver version and, I must say, we are satisfied with the color, although it has one caveat: if the lighting is yellowish (for example, in the case of conventional incandescent lamps), then the smartphone also looks yellowish.

Safety

One of the main features of the Samsung Galaxy Note7 is the iris scanner. Although smartphones with this option are slowly starting to appear on the market, it is still a curiosity, and we were all the more interested in how one of the leaders in smartphone manufacturing implements it.

Let's say right away: the results exceeded all our expectations. And everyone who saw the work of the scanner said one thing: “Wow!”. The beauty of the technology is that recognition is almost instantaneous, in most cases it is error-free (it feels like about 90% of successful unlocks on the first try), and at the same time you do not need to keep your smartphone at a certain distance (that is, of course , it cannot be held too close to the face or, conversely, too far, but the allowable range is very large).

Another significant point is the correct operation of the scanner in different lighting conditions. In the dark - no problem, in the bright sun - too.

Finally, the third: the use of an iris scanner does not at all cancel the possibility of using a fingerprint scanner. That is, you can alternate the unlock type depending on the situation. At some point, it’s more convenient to raise the phone to eye level, at some point, it’s easier to put your finger on it.

However, all this is top-level protection, and at the bottom there is still a pin code or pattern. So if you, for example, have an insufficiently reliable pin code, then the iris scanner will not make the smartphone more secure, because if it fails, an attacker can always try to guess the password. It would probably be advisable in the future to make the possibility of using biometric protection as a basic option as it is more difficult to crack. That is, in any case, the user had to use one of two options - either one or the other scanner. It is clear that there is concern: what if finger recognition does not work (this happens with all smartphones)? But for this case, there is now an iris scanner. And vice versa.

Returning to the description of the iris scanner in the Samsung Galaxy Note7, we note only one drawback: in order to launch it, you need to press the power button and swipe your finger across the screen, that is, do two actions (or even three, if you count lifting the smartphone as a separate action at eye level). Whereas to unlock with a fingerprint, just one press of the right finger on the Home button is enough.

Screen

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than the screen of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens (on the left is Nexus 7, on the right is Samsung Galaxy Note7, then they can be distinguished by size):

The screen on the Samsung Galaxy Note7 is slightly darker (brightness in photos is 113 versus 116 on the Nexus 7) and doesn't have a pronounced tint. The ghosting of reflected objects in the Samsung Galaxy Note7 screen is very weak, which indicates that there is no air gap between the screen layers. Due to the smaller number of borders (glass/air type) with very different refractive indices, screens without an air gap look better in conditions of intense external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be replaced. On the outer surface of the Samsung Galaxy Note7 screen there is a special oleophobic (grease-repellent) coating (effective, slightly better than Nexus 7), so fingerprints are removed much easier and appear at a slower rate than in the case of ordinary glass.

When displaying a white field in full screen and with manual brightness control, its maximum value was 350 cd/m², the minimum was 1.5 cd/m². You also need to take into account the fact that in this case the smaller the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. As a result, readability during the day in the sun should be at a fairly good level. The reduced brightness level allows you to use the device without any problems even in complete darkness. Automatic brightness control works according to the light sensor (it is located to the left of the front speaker slot). The operation of this function depends on the position of the brightness control, with which the user can try to set the desired brightness level under the current conditions. If the brightness slider is set to maximum in office conditions, then in complete darkness the auto-brightness function reduces the brightness to 7.7 cd / m² (darkish), in an office lit by artificial light (approximately 550 lux) it sets it to 350 cd / m² (excessively bright) , in a very bright environment (corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) increases to 520 cd / m² (enough), and conditionally in direct sunlight, the screen brightness increases to 570 cd / m² ( information will be visible). If everything is still in office conditions, the brightness slider is at half the scale, then the screen brightness for the four conditions indicated above is as follows: 7.7, 130, 495 and 570 cd / m² (the first value is rather low). If the brightness control is set to minimum - 1.4, 1.4, 350 and 540 cd/m² (now the first two values ​​are too low). The result did not satisfy us, so we moved the slider first by 50% in the office, then a little to the right of the minimum in complete darkness. We got - 10, 170, 535 and 560 cd / m² (the perfect combination). It turns out that the auto-brightness function works adequately and to some extent allows the user to customize their work to individual requirements. At any level of brightness there is a significant modulation with a frequency of approximately 60 or 240 Hz. The figure below shows brightness (vertical axis) versus time (horizontal axis) for several brightness settings:

It can be seen that at maximum and close to it, the modulation amplitude is not very large; as a result, there is no visible flicker. However, when the brightness is lowered, modulation with a large relative amplitude appears, and the presence of such modulation can already be seen in the test for the presence of a stroboscopic effect or simply with rapid eye movement. Depending on individual sensitivity, such flickering can cause increased fatigue.

This screen uses a Super AMOLED matrix - an active matrix on organic light emitting diodes. A full color image is created using subpixels of three colors - red (R), green (G) and blue (B), but there are twice as many green subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a microphoto:

For comparison, you can see the gallery of microphotographs of screens used in mobile technology.

On the fragment above, you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), while repeating these fragments, you can lay out the entire screen without gaps and overlap. For such matrices, Samsung introduced the name PenTile RGBG. The manufacturer considers the screen resolution based on green subpixels, on the other two it will be two times lower. The location and shape of the sub-pixels in this variant is close to the case of the Samsung Galaxy S4 screen and some other newer Samsung devices (and not only) with AMOLED screens. This version of PenTile RGBG is better than the old one with red squares, blue rectangles and stripes of green subpixels. However, some uneven contrasting borders and other artifacts are still present. However, due to the very high resolution, they have minimal effect on image quality.

The screen has excellent viewing angles. True, the white color, when deviated even at small angles, alternately acquires a light blue-green and pinkish tint, but the black color remains just black at any angle. It is so black that the contrast setting is not applicable in this case. When viewed perpendicularly, the uniformity of the white field is excellent. For comparison, here are photos in which the screens of the Samsung Galaxy Note7 (profile Basic) and the second comparison participant, the same images were displayed, while the brightness of the screens was initially set to approximately 200 cd / m², and the color balance on the camera was forcibly switched to 6500 K. White field:

Note the excellent uniformity of brightness and hue of the white field (with the exception of darkening and changing hue towards the curled edges). And a test picture (profile Basic):

The color reproduction is good, the colors are moderately saturated, the color balance of the screens is slightly different. Note that in this case, the picture occupies the height (with this screen orientation) of the entire area available for displaying the image and goes to the curved edges of the screen, which leads to darkening and color distortion. Also, in the light, these areas almost always glare, which makes it even more difficult to view images displayed in full screen. And even the picture of films with an aspect ratio of 16:9 comes to bends, which greatly interferes with watching movies. The photo above was obtained after choosing a profile Basic in the screen settings, there are four of them:

Profile adaptive display differs in some kind of automatic adjustment of color rendering to the type of displayed image and environmental conditions, which is obtained by selecting the two remaining profiles shown below.

AMOLED cinema:

Saturation and color contrast are markedly increased.

AMOLED photo:

Saturation is slightly lower, color contrast is closer to normal. Now at an angle of approximately 45 degrees to the plane and to the side of the screen (profile AMOLED cinema). White field:

The brightness at an angle on both screens has noticeably decreased (in order to avoid strong darkening, the shutter speed is increased compared to previous photos), but in the case of Samsung, the drop in brightness is much less pronounced. As a result, with formally the same brightness, the Samsung Galaxy Note7 screen visually looks much brighter (compared to LCD screens), since you often have to look at the screen of a mobile device at least at a slight angle. And a test picture:

It can be seen that the colors have not changed much on both screens and the brightness of Samsung at an angle is noticeably higher. Switching the state of the matrix elements is almost instantaneous, but there may be a step about 17 ms wide at the turn-on front (which corresponds to a screen refresh rate of 60 Hz). For example, the dependence of brightness on time looks like this when moving from black to white and vice versa:

In some conditions, the presence of such a step can lead to plumes trailing behind moving objects. However, dynamic scenes in films on OLED screens are distinguished by high definition and even some “twitchy” movements.

For all three profiles, the gamma curve constructed from 32 points with equal intervals according to the numerical value of the shade of gray coincided. There is no significant blockage either in the highlights or in the shadows, and the exponent of the approximating power function is 2.14, which is slightly less than the standard value of 2.2, while the real gamma curve deviates little from the exponential dependence (in parentheses, the exponent of the approximating power function is given functions and coefficient of determination):

Recall that in the case of OLED screens, the brightness of image fragments dynamically changes in accordance with the nature of the displayed image - it decreases for images that are generally bright. As a result, the resulting dependence of brightness on hue (gamma curve) most likely does not correspond slightly to the gamma curve of a static image, since the measurements were carried out with sequential grayscale output almost on the entire screen.

Color gamut in profile case AMOLED cinema very wide:

When choosing a profile AMOLED photo coverage is pressed to the borders of Adobe RGB:

When choosing a profile Basic coverage is compressed to sRGB borders:

Without correction, the spectra of the components are very well separated:

In the case of a profile Basic with the maximum correction, the color components are already noticeably mixed with each other:

Note that on screens with a wide color gamut without proper color correction, normal images optimized for sRGB devices look unnaturally saturated. Hence the recommendation - in most cases, watching movies, photos and everything natural is better when choosing a profile Basic, and only if the photo was taken on an Adobe RGB setting does it make sense to switch the profile to AMOLED photo. Profile AMOLED cinema, despite the name, is the least suitable for watching movies and anything else.

The balance of shades on the gray scale is good. The color temperature is close to 6500 K, while this parameter does not change very much in a significant part of the gray scale, which improves the visual perception of the color balance. The deviation from the blackbody spectrum (ΔE) remains below 10 units for most of the gray scale, which is considered a good indicator for a consumer device, and also does not change very much:

(The darkest areas of the gray scale in most cases can be ignored, since there the color balance does not matter much, and the measurement error of color characteristics at low brightness is large.)

Let's summarize. The screen has a very high maximum brightness and has excellent anti-glare properties, so the device can be used outdoors without any problems even on a sunny summer day. In complete darkness, the brightness can be reduced to a comfortable value. It is acceptable (and even necessary in bright light) to use a mode with automatic brightness adjustment, which works adequately. The advantages of the screen include an effective oleophobic coating, as well as a color gamut close to sRGB and a good color balance. At the same time, let's recall the general advantages of OLED screens: true black color (if nothing is reflected on the screen), excellent white field uniformity, noticeably smaller than that of LCDs, and a drop in image brightness when viewed from an angle. The disadvantages include modulation of the screen brightness. Users who are particularly sensitive to flicker may experience fatigue as a result. However, overall the screen quality is very high. Separately, we note that from the point of view of image quality, curved edges are only harmful, since this design find introduces very noticeable color tone distortion and reduces brightness at the edges of the picture, and in ambient light conditions leads to inevitable glare at least along one long side of the screen.

Performance

The smartphone runs on the same Exynos 8890 Octa SoC as the Samsung Galaxy S7 Edge. The chip is made using the 14 nm process technology, enhanced with FinFET LPP (Low-Power Plus) technology. It uses Mongoose CPU cores (four cores with a frequency of 2.6 GHz) and four Cortex-A53 cores already familiar to us with a frequency of 1.6 GHz.

The Mali-T880 acts as a graphics accelerator. The amount of RAM is 4 GB, like the S7 Edge. And an important detail: 500 MB of these 4 GB is reserved for the needs of the GPU, so the benchmarks define the amount of RAM in both smartphones as 3.5 GB.

In the Samsung Galaxy S7 Edge review, you can find a detailed performance comparison of Exynos 8890 Octa SoC with competing solutions. Here we will not focus on this and focus on understanding if there is any difference in performance between the S7 Edge and Note7.

Let's start with browser benchmarks: SunSpider 1.0.2, Octane Benchmark, Kraken Benchmark and . On all Android devices, we used the Chrome browser, on iOS - Safari. If there is a dash in the table field, it means that the corresponding smartphone has not been tested in this benchmark (or in this version of this benchmark).

The small differences between the results of the two Samsung smartphones are well within the limits of the possible measurement error.

Now let's see how the gadget performs in complex benchmarks - AnTuTu 6 and Geekbench 3.

And again, an unambiguous picture does not work out: in AnTuTu, the new product overtakes the S7 Edge, and in Geekbench it is inferior to it. The situation is aggravated by the fact that the scatter of results is too large to attribute this to an error. However, let's not forget that the Note7 has newer software installed than the S7 Edge at the time of its launch, so this may be the reason for the picture.

The last group of benchmarks is dedicated to testing GPU performance. We used 3DMark, GFXBench and Bonsai Benchmark. All of them demonstrate real 3D scenes and allow you to visually see how devices cope with them.

Let's start with GFXBench. Recall that Offscreen tests are a display of a 1080p image on the screen, regardless of the actual screen resolution. And Onscreen tests are the output of a picture in the resolution that corresponds to the screen resolution of the device. That is, Offscreen tests are indicative in terms of the abstract performance of the SoC, and Onscreen tests are indicative of the comfort of playing on a specific device. In addition, this year's Android devices used the new Car Chase scene, which uses OpenGL ES 3.1. This standard is not supported by the iPhone, so this scene is not available there, nor is the ES 3.1 version of the Manhattan scene. However, there is enough data to draw conclusions.

And here there is already almost complete parity between S7 Edge and Note7 (except for the strange loss of new items in one of the modes).

And the last test is 3DMark. The Sling Shot scene ran in OpenGL ES 3.1 on Android devices and OpenGL 3.0 on iPhone.

The abnormally high result in the Ice Storm Unlimited mode is difficult to explain, but it is what it is.

In general, the benchmarks allow us to admit that the performance of the Samsung Galaxy Note7 and S7 Edge is approximately identical, and at the moment this is the top level. At least until the new iPhone comes out.

Video playback

We could not check the theoretically possible support for adapters for outputting images to an external device due to the lack of an adapter option that connects to the USB Type-C port, so we had to limit ourselves to testing the output of video files to the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see "Methodology for testing video signal playback and display devices. Version 1 (for mobile devices)"). Screenshots with a shutter speed of 1 s helped determine the nature of the output frames of video files with different parameters: the resolution varied (1280 by 720 (720p), 1920 by 1080 (1080p) and 3840 by 2160 (4K) pixels) and frame rate (24, 25, 30, 50 and 60 fps). In tests, we used the MX Player video player in Hardware mode. The test results are summarized in the table:

Red marks indicate possible problems with the playback of the respective files.

According to the criteria for displaying frames, the quality of playing video files on the screen of the device itself is very good, since frames (or groups of frames) can be displayed with more or less uniform alternation of intervals and without frame drops. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, going to the bends. The clarity of the picture is high, but not ideal, since there is no escape from interpolation to the screen resolution. However, for the sake of experiment, you can switch to the one-to-one mode by pixels, there will be no interpolation, but PenTile features will appear - the vertical world through the pixel will be in the grid, and the horizontal one will be a little greenish. This is on test worlds, the described artifacts are absent on real frames. The brightness range displayed on the screen actually corresponds to the standard range of 16-235: in the shadows, only a couple of shades merge with black, and in the highlights, all gradations of shades are displayed.

Autonomy and heating

One of the most interesting issues in the case of flagships is the battery life, since, as we understand, the study of the characteristics will not necessarily be able to give an idea of ​​​​this parameter. And even "laboratory" tests are not always indicative. That is why we used the Samsung Galaxy Note7 as the main and only smartphone and were able to evaluate the battery life "on our own skin".

Knowing that the battery capacity is slightly reduced compared to the S7 Edge, and the screen area is slightly larger, we were afraid that the phone would have to be charged more often than the S7 Edge. But in fact, we did not find any significant difference. Like the S7 Edge, the novelty can work in medium-intensive mode for two days. Medium intensity means the following: automatic mail check every 10 minutes (sometimes manual checks in addition to this), frequent use of social networks and instant messengers (FB Messenger, Telegram, SMS), some amount of web surfing, irregular and short-term use of Yandex.Maps and Yandex .Transport, as well as about half an hour of telephone conversations a day.

Obviously, if you add watching videos and 3D games to this list, the picture will change. But if for you a smartphone is primarily a working tool, then you can safely charge it no more than every other night.

In addition to "real" testing, we have also added our standard test modes: Guided Tour in the Epic Citadel benchmark (3D game simulation) and YouTube video playback. And here the results are less impressive. In Epic Citadel, the smartphone lasted only 3 hours and 55 minutes - significantly less than many competitors. And when watching the video, the duration of the work was 12 hours 50 minutes, which is also not so hot, what a result, but still acceptable.

Simply put, the Samsung Galaxy Note7 is more for everyday business use than for gaming and entertainment. Probably, the SoC does not work very economically in the same games. As a result, strong heating and rapid loss of battery power.

Below are thermal images of the back surface obtained after 10 minutes of running a battery test in the GFXBenchmark program:

It can be seen that the heating is strongly localized above the center and close to the right edge, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was 45 degrees (at an ambient temperature of 24 degrees), which is significantly higher than the average value in this test for modern smartphones.

Even when the article was written, a scandal erupted with the exploding batteries of the Galaxy Note7. We, fortunately, did not have such incidents, but it is clear that the problem is serious. We hope that Samsung will be able to solve it, and by the start of smartphone sales in Russia there will be no more problems.

In conclusion, we suggest watching our video review of the Samsung Galaxy Note7 smartphone and Samsung Gear VR virtual reality glasses:

In the second part of the article, you will find a detailed test of the Samsung Galaxy Note7 camera.

Each new representative of the Note line is expected by the public with open impatience, and then is subjected to the closest scrutiny. Unsurprisingly, the Galaxy Note 7 is no exception. A simple study of the technical characteristics of this smartphone makes the heart of any more or less advanced user tremble, but we decided to study its capabilities in the most detailed way, join us.

Ah, yes. To everyone who was waiting for the Note 6 model in bewilderment and did not wait, we remind you that the “six” was deliberately skipped by the manufacturer in order to bring all its flagship Galaxy (Note and S lines) to such a “common denominator”.

Package is a solid black matte box. Like theater off a hanger, the solidity of the new Galaxy Note 7 starts from here, from the box.

Contents of delivery includes a key clip, tweezers with interchangeable stylus tips, a wired headset, a charger and a USB cable for it. Of particular interest here is a pair of adapters from USB-C to full-fledged USB and microUSB: connect a USB flash drive and use third-party charging.

Design has not changed compared to its predecessors: we have a glass sandwich with a metal frame between the front and rear plates.

The glass is convex, in the company of curved side frames it creates a wonderful effect of a screen floating in the air. By the way, these very bends here are not as strong as those of the same Galaxy S7 Edge.

Dimensions 153.5 x 73.9 x 7.9 mm, weight 169 g. It goes without saying that for its rather large screen, the Galaxy Note 7 feels like a rather compact device.

Protection against dust and moisture meets the IP68 standard, by the way, this is the first Note to receive such protection.

The standard colors - black, silver and gold - are diluted with a fresh blue version.

On the right we see a thin power button.

On the bottom, we are greeted by the current year's USB Type-C port, next to a microphone hole, an audio port, a speaker grill and an S Pen jack.

On the left are the usual separate volume buttons.

At the top we see a tray for SIM and a memory card, here is an additional microphone.

The rear panel is bent to the side edges, due to which it is convenient to hold the smartphone in your hands, despite its frankly large size. The layout of all the elements is familiar from previous Galaxy models: here is the camera, flash, heart rate sensor and oxygen saturation sensor. All these elements have long been familiar to fans of the brand. The glass of the back cover, of course, collects all possible fingerprints, but if you put it in order in time, it will look very solid.

On the front panel we see a standard set of sensors, supplemented by an infrared camera for reading the iris, a conversational speaker and a front camera,

below it - a pair of touch buttons and a physical “Home”, combined with a fingerprint scanner.

Iris Scanner was mentioned in almost all the leaks regarding Note 7 and, as you can see, they did not lie. However, it is not so easy to use it: if taking off glasses is a simple matter, then no one wants to pick out contact lenses a hundred times a day.

Thanks to the infrared camera, recognition works even in the dark, but in bright light there may be problems. If the iris is not recognized for some reason, you can confirm your identity using a fingerprint sensor or a digital password.

Admittedly, the new autumn protection works quickly and, for the most part, accurately, but it will not work to “deceive” the sensor with the help of a photograph.

In addition to unlocking the smartphone in general, the iris scanner can be used to restrict access to personal photos, records, or other types of files.

Fingerprint's scanner we will mention only in passing, it is not new to us. Everything works well here, recognition is fast and trouble-free.

S Pen, along with the device as a whole, received protection from dust and moisture, moreover, in such unfavorable conditions, it will remain operational. But his improvements don't end there. So, the pen has become more accurate and sensitive, now it “understands” twice as many degrees of pressure: 4096. Externally, the stylus has become thinner, the selection button has remained in its place, and to remove it from the socket, you still need to use a special button. Speaking of the socket, the problem with the incorrectly inserted stylus seems to be solved forever: now it just won't fit in the back. Fool proof, pure and simple.

As for how it works, the S Pen is fast and accurate, and OCR works great. To the previous functions, a screen magnifier (up to 300% magnification), quick translation (including from images) and the creation of GIF animations were added. But S Note and Action memo have disappeared, now their functions are combined in the Notes application. Considering that the programs largely duplicated each other, we consider this the right decision, and we hasten to reassure all users of other Galaxy Note models: you can easily transfer previously created notes to a new application.

Screen has the same diagonal of 5.7 inches with a resolution of QuadHD (2560x1440) unchanged for several generations, which gives a pixel density of 518 ppi. The SuperAMOLED matrix has not left the smartphone either, but Gorilla Glass 5 now acts as a protective glass. If you are seriously interested in buying Note 7, you have probably already seen that creepy video from the JerryRigEverything channel, where the author safely scratches the glass with rather soft tools, which Gorilla Glass 4 did not succumb. Of course, we cannot say that your keys will leave (or not) the same devastating scratches, but still we do not recommend risking the appearance of such an expensive device.

Well, what can we say about the quality of the display of the flagship smartphone? He's great. There is nothing to complain about either the brightness, or the viewing angles, or the color reproduction. Note 7 fully justifies its status as an advanced device.

An interesting feature of the screen is support for HDR video format, which guarantees smoother color transitions and a wide dynamic range. However, so far this is only a theoretical possibility: there is practically no suitable content on the Web.

As for the curved sidewalls, there are no accidental clicks on them, and the SPen works great in these areas.

The screen temperature settings are the same, from the new one - a blue filter (aka, night mode) has appeared to make the eyes less tired. This mode is scheduled to work.

Let's also mention the Always On Display option, familiar to users from the Galaxy S7. Here it has become better and now shows notifications not only from standard applications, but also from third-party ones, which greatly expands the scope of an already interesting function.

Sound both from the multimedia speaker and from the headphones, is at a high level: detailed and loud. All sorts of effects and a seven-band equalizer are provided.

operating system Android 6.0.1 Marshmallow, of course, will be updated to the latest "seven" as soon as possible, but for now, the new shell, which is called Grace UX, is of interest.

The shell turned out to be minimalistic, lightweight and quite interesting. The icons in it are rounded, executed in deliberately simple lines and colors.

The curtain is now made with light colors, quick settings are called up in the additional submenu by swiping down, the SIM card settings are also placed here.

The settings menu has changed dramatically.

A search bar appeared in the application menu.

Not to mention the brand new Samsung Cloud service. In fact, just cloud storage, elegantly integrated into the smartphone interface. All Note 7 users will get 15GB of space here. In addition to actually storing files, it can be used to back up data.

And, of course, it would be stupid to have curved edges, but not have software for it. Note7 provides Edge UI, with applications placed on the sidebars (new ones were added to the usual list) or contacts.

A little prank from Samsung - the main color of the interface will now match the color of your smartphone. However, if desired, it is always easy to change in the settings.

Performance approximately equal on both modifications of the smartphone. As we remember, there are two of them: one is based on the 64-bit Samsung Exynos 8890, the other is based on the Snapdragon 820. The first processor is complemented by the Mali-T880 MP12 graphics, the second is Adreno 530. Both versions have 4 GB of RAM, built-in memory is standard 64 GB. Perhaps this would be enough for almost any need, but here it is also complemented by a slot for a memory card. Also for the Chinese market, a 6/128 GB option is provided.

In any of these options, it is not just fast, it is a lightning-fast smartphone that can handle any of your requirements and tasks, whether it be applications, games, synthetic tests, augmented or virtual reality.

Be that as it may, the numbers in the benchmarks are amazing, and in the final version, which will hit the stores, it may be even cooler.

Interfaces are represented by a standard set that is not worthy of close attention: LTE, NFC, Wi-Fi 802.11 b / g / n / ac, Bluetooth 4.2 and GLONASS and GPS navigation systems.

Camera the main one is equipped with a 12 MP module with f / 1.7 aperture and Dual Pixel technology, phase detection autofocus and single-section flash. Optical image stabilization is also provided. The camera has a high speed of operation, and this applies to focusing, and launching and saving finished images.

The application interface has also been updated: now all controls are sharpened for swipes. The output was intuitive and fast.

This module shows excellent results, regardless of the shooting conditions: whether it is a bright sunny afternoon, evening or a gloomy room, the pictures remain detailed, with natural colors and the complete absence of noise.

Video recording is carried out as much as possible in 4K, there is a slow-motion recording mode.

The 5 MP front camera with f/1.7 aperture is not equipped with any special technological frills, but it also shows excellent performance and excellent pictures. The most interesting thing here is video shooting: it is available in 2K quality.

Battery has a capacity of 3500 mAh. This smartphone is enough for a full day of battery life in mixed mode, that is, approximately 5 hours of screen or 14 hours of video.

There is wireless and fast charging; From zero to maximum, the smartphone charges in an hour and a half.

It is impossible to ignore the new energy-saving mode, which, in theory, should extend the battery life of the device by 35 hours. Under the laconic names Mid and Max, there are two levels of energy saving, and on each of them the user can make his own adjustments. Especially interesting is the lowering of the screen resolution in Mid to FullHD (1920x1080), and in “Max” to HD (1280x720). Until now, no manufacturer has resorted to such a method to increase the autonomy of their devices, although third-party analogues exist and are actively used by users.

Accessories for the Galaxy Note 7 are so diverse that it’s simply impossible to dwell on each item in detail. We will only mention a large number of cases, including those with an external battery of 3100 mAh and the possibility of wireless charging, a pair of lenses or diodes for alerts. The latter option is already familiar to us from previous versions, but with the new LED View Cover, new possibilities for customization have appeared, it can also be used to accept or reject calls and manage some programs, for example, an alarm clock or a timer.

And, of course, we have not forgotten about the new Gear VR virtual reality helmet, we just think that such an interesting device deserves a separate review.

Generally, Galaxy Note 7 is beautiful, what can I add? If the Note 4 and 5 were more of a treadmill, then the Seven is indeed a step forward. And it’s not even about advanced technologies that have always been present in Notes, but about pleasant little things: finally a curved screen, protection from dust and moisture, a compact body, despite a consistently large screen, an improved stylus ... And, of course, a scanner iris - Note 7 was one of the first "androids" with such an identification system and certainly the first eminent.

Are you interested in disadvantages? Well, here the case is easily soiled. Glass, you know.

Of course, like everything good, you have to pay for such charms, and a considerable price: in this case, about $ 900.
