Attention. Unlike the preview, here you are reading the review of the final sample, as a result, you can evaluate all aspects of the phone without any discounts. Some parts are repeated with the first material, some are greatly supplemented and expanded. Here is the final review.

Positioning

The success of the Galaxy S was unpredictable, and for such a product, it achieved phenomenal sales. The model is an undisputed bestseller, it set the bar for the Android phone market, but it also caused problems within Samsung. No one expected a resounding success, as a result, no one could predict that the demand for phones would skyrocket. The company was let down by the lack of SuperAMOLED screens, their shortage did not allow for large sales, the demand for the model is high, but it is not available in many markets in sufficient quantities. As part of the move, Samsung has launched a cheaper variant of the Galaxy S, the i9003, which uses a SuperClear TFT display. It loses SuperAMOLED in all respects, but it remains one of the best screens on the market. At the same time, the cost of i9003 with a minimum amount of memory is 100-120 euros less than the original Galaxy S, the difference in price will increase even more over time. It's not a bad deal and will exploit the popularity of the original Galaxy S.

After the announcements at CES, when NVIDIA showed the first solutions based on Tegra2, in particular, LG Optimus 2x, Motorola Atrix 4G, Motorola DROID Bionic, a natural question arose: how can Samsung respond to these devices? It seemed that dual-core processors are becoming a necessity in flagship solutions, a good marketing ploy, even if there is no practical need for them yet, since there is no corresponding software, games, and the speed increase in ordinary applications is not so great. But at CES, Samsung didn't say a single word about such plans. The reason is that the company wanted to close the gap between the announcement of the product and its appearance on the market as much as possible. So that potential buyers can get this solution at the same time as competitors.

Does Samsung count on the success of its updated flagship? Definitely yes, and there are simply no prerequisites to believe that he will not be successful. Based on the sales of the previous device, this model will make a market for itself. She has several unique features that are not yet available from competitors. The first is the technology race in the field of screens. The new term is SuperAMOLED +, an improved version of the previous display, which has not had time to become obsolete, and competitors simply do not have an analogue. Why such a technology race is needed, I don’t know, but the screen becomes a visible advantage of Samsung’s flagships. One of the strengths. I like the Galaxy S for the quality of the screen, but it's not as sharp as the iPhone 4, it's not as sharp, the fonts are a bit washed out. In the new version of SuperAmoled +, the sharpness was increased, not yet the iPhone, but not the Galaxy S either.

The second feature is not yet applicable in practice in most situations, but it gives a huge reserve for the future, this is a dual-core processor. For fans of technology, such a processor has an undoubted advantage, its presence adds extra shine to the phone. But for practical people this is not the case. The presence of such a processor has no undoubted and quick benefits. Another thing is that over time, more and more programs will appear for such solutions, and then this phone will show its capabilities.

In terms of technology, the first Galaxy S set the bar very high, it was not a demonstration of technology for its own sake, but a demonstration of how to tie all the latest technologies into one compelling product. The S II went even further, this is the first phone that supports Wi-Fi Direct, does not need special software to work with any computer and synchronize data, the phone can send files via Wi-Fi, has a number of additional programs that are not familiar to other Android phones, but which will soon become standard. I can list the technologies used for quite a long time (NFC, MHL, and so on), there are an impressive number of them here. Without any discounts, Samsung created the flagship and did it without exchanging for trifles. Unfortunately, there is not a single device on the market that is similar in terms of characteristics and combined capabilities. Devices based on NVIDIA Tegra 2 came close to the Galaxy S II, but as a rule, they have a much worse camera, a larger size, and noticeably worse displays. Surprisingly, Samsung has created a flagship with an excellent price / quality ratio for its segment. A year will pass, and functionally the device will remain at the level of the best solutions, it will not be overshadowed by other models, although more interesting solutions from different companies will appear. This product is positioned as a long-term flagship, that is, a model that is bought in order not to change the phone for a long time. The life span of this device for most markets and consumers will be maximum.

It is also worth noting the HTC Sensation model, which is technically very similar to the Galaxy II (dual-core processor, 1.2 GHz frequency, but the camera is worse, the built-in memory is smaller, the screen is simpler). This model wins with the presence of the Sense 3.0 shell, but at a similar cost, Samsung has a technological advantage. In any case, both models look extremely attractive, and the choice between them will be quite difficult.

The positioning of the phone as a flagship determines the portrait of its consumer, these are primarily those who buy the latest and best solutions. Of course, this device also applies to them. The second and notable category is technology enthusiasts (geeks). Those who care about how powerful their phone is. For them, this model offers a win-win option, because other phones simply have nothing comparable in terms of technology. For practical buyers, this is an interesting model, since for a long time it will be possible to be sure that it remains relevant and does not require replacement.

Design, dimensions, controls

Here I had to hear a lot of different opinions. Someone judged by the picture and said that the model looks exactly the same as the previous device, someone from the owners of the previous Galaxy complained that the device became wider, and this is not very convenient. Someone was just waiting for a different look. Samsung felt that the design of the first Galaxy S was successful, and sales confirm this. And we decided not to change anything. To some extent, this approach makes sense.

At the same time, due to the fact that the area of ​​​​the apparatus has become larger, it has been made thinner. Impressive 8.5 mm (in the press release they say even 8.49 mm, but we will not calculate with such accuracy?), make this device one of the thinnest on the market. Sony Ericsson Arc immediately comes to mind, it has a thickness of 8.7 mm, which also looks thin, due to this the device is perceived in a completely different way, it makes an impression. A forgotten trend that was in phones 4 years ago has revived again for the smartphone segment. Remember Samsung's Ultra series, and before that there was a device with a case thickness of 9 mm, and this was perceived as a breakthrough. Everything new is well forgotten old.

Comparison with Sony Ericsson Arc:

By the way, Samsung Galaxy S II somehow reminded me of Sony Ericsson Arc and in terms of proportions, it is possible that the size and screen diagonal leave an imprint, it is similar in both models. In Arc 4.2 inches, while in Samsung 4.27, the difference is not deafening. But the screen in Samsung is orders of magnitude better and more interesting. The Galaxy S II uses DNIe + technology (that's where the plus sign in the screen name comes from). This is a processor that processes any graphics, such as photos, pictures, videos, and makes it better for viewing on the phone screen. A similar technology is used in all TVs from Samsung. Curiously, something similar under the name BraviaEngine is used in Sony Ericsson Arc. These technologies are not used in the interface, that is, they are not responsible for drawing the menu.

The size of the phone is 125.3 x 66.1 x 8.5 mm (Galaxy S has 122.4x64.2x9.9 mm), weight is 116 grams. For my taste, the device is a bit too wide, to some this will seem like a disadvantage. But you adapt to it quickly, there is no discomfort. It's nice that the device is invisible in your pocket, it also looks good in a shirt.

Comparison with Samsung Galaxy S:

The answer, why the back cover is made of plastic and not metal, you find pretty quickly. With active use of the phone, when you watch videos, download large files, transfer them, it starts to get very hot. If the back cover were metal, then it would be impossible to touch the device, it would burn. The cellular structure of plastic was invented for a reason, it is a kind of passive radiator. But even with it, the phone sometimes warms up, does not burn, but you feel the heat. The warmest areas around the camera.

The lid is very thin and when you snap it on you have to run your finger around the perimeter to make sure it fits snugly. Sometimes you close the lid not completely, and this creates certain inconveniences. When dropped, the cover flies off, it is knocked out by the battery. My phone flew several times, but the cover did not receive any damage. Despite the thinness of the plastic, it is resistant to both shock and bending.

The phone has a 2-megapixel front camera, a proximity sensor, as well as ambient light. The central key is mechanical, but the menu and back buttons are touch-sensitive. On the left side there is a paired volume control button, on the right side there is an on/off button. It was not possible to find the camera key, as before it is not there, and the camera will have to be called from the menu.

At the top end there is a 3.5 mm headphone jack, the microUSB connector has been moved down. An 8-megapixel camera lens is visible on the back surface, plus an LED flash, and a speaker is located at the bottom.

For a few weeks, my main phone was the Galaxy II, so it went through fire, water, and also copper pipes. The case does not wear out anywhere, with the exception of the rear protrusion, a slight abrasion appears here, over time it will intensify. It is visible well only in the light and at the right angle. The second point is the back cover. In my pocket, it rubbed against the lining, unevenly, separate worn areas appeared. But I’ll say again, they are visible with a very careful study of the phone, in fact it’s hard to find them. In total, everything is expected, the plastic case has both its advantages (weight, practicality) and disadvantages.

I confess honestly that I do not share the opinion of many people that the phone case must be made of metal, especially if it is a flagship model. It can be made of plastic, glass or other materials. The question is how the material behaves over time, ages or not, wipes off or not. For example, the glass used in the Apple iPhone 4 is relatively fragile, dropping the device on the pavement can break it. Does this stop someone from buying a device? I think no. This is one of its features. The model turned out to be very small in weight, but at the same time wide, and this is captivating. Constantly using HTC Incredible S and Galaxy II, I caught myself thinking that Galaxy is more convenient for me. The reason is the weight and thickness of the case.

Display

Those who claim that SuperAMOLED Plus is just a marketing ploy should take a look at how different the picture on it is compared to regular SuperAMOLED. It is brighter, sharper with an increased screen diagonal, but the main thing is that the screen consumes less energy. An option to save energy has appeared in the settings, when power consumption is adjusted depending on the picture that is currently displayed (using DNIe +). This technology is also used in all Samsung TVs, a special processor analyzes the information and then improves the picture, making it more beautiful for us. The side effect is that the phone can now analyze how energy is being spent. Wallpaper selection also takes into account the fact that AMOLED screens use energy differently depending on the color. A similar technology is used by Sony Ericsson, it is called the Bravia Engine, but the gain on TFT screens is not so noticeable, rather, the technology is there only to visually improve the displayed picture.

Let's get back to screen technology. The first SuperAMOLED matrices use PenTile technology, when one dot on the screen is formed from two subpixels. Surprisingly, this caused quite a heated discussion in many forums, in which it was claimed that the effective resolution of any screen with PenTile technology is at least a third lower than stated. A rather bold and stupid statement, since the number of dots was no different from any screen, and if the manufacturer spoke about a matrix of 800x480 pixels, then there were just such a number of them on the screen. No more, no less.

Another thing is that in some aspects, fewer subpixels gave visible distortion on the screen, which, coupled with high definition, annoyed some users. For example, for the first generation SuperAMOLED, the fonts had a sharp outline with a ladder, in fact, this is the only visible difference from most screens, which results from the use of PenTile technology. Just look at the icon labels on the main screen and see this effect on the same Galaxy S. Comparison with the second Galaxy will show that there is nothing like it.

The explanation lies in the Real RGB Stripe technology, which was used in SuperAMOLED Plus matrices. Now a single point on the screen is formed not by two, but by three sub-points. The picture from Samsung Displays shows the difference, the increased number of subdots makes the picture smoother, fonts included, there are no sharply defined contours that could be annoying. I honestly admit that until I started discussing this topic, procrastinating it, I didn’t even pay attention to fonts. But then, of course, I saw this sharpness, although this had no effect on my perception of the previous Galaxy.

In the sun, the screen behaves worse than in the first Galaxy, the explanation is that the size of the matrix has increased, but the resolution has remained the same, plus the technology has changed. The picture is readable at a right angle or in a not very bright sun. But otherwise, everything is exactly the same as on other types of screens, there is no advantage that was in the first SuperAMOLED.

At the moment, SuperAMOLED Plus technology does not allow you to create screens with a dot density of more than 200 ppi, the iPhone has a matrix with more than 300 ppi. Samsung will change the manufacturing technology of matrices in order to get more than 300 ppi already in 2011.

For my taste, the picture on the SuperAMOLED Plus looks smoother, the brightness control is well chosen. But the main point is related to the fact that the user can choose the saturation of the picture (Movie, Standard, Dynamic). In fact, this is a setting that allows you to set the color temperature of the screen, change the color saturation. Someone likes bright colors - leave the standard option. Someone likes not so bright colors - choose the Movie mode.

The screen diagonal is 4.3 inches (in the previous model it was 4 inches, but the difference is huge, striking), the resolution is 800x480 pixels (displays 16 million colors). In practical terms, the display is extremely convenient, there is an automatic adjustment of the brightness of the image depending on the lighting. The protective glass is tempered, covered with a special anti-reflective material. Also, the screen has an oleophobic coating, which in theory means that it does not get dirty with your hands. A similar coating is used in the Apple iPhone. Users of this device know that prints still remain, they are just slightly smaller. Exactly the same story here. There are greasy traces, but they are not so conspicuous.

Samsung devices also use VibeZ technology - when you press the keys, the body vibrates, which confirms your action.

Up to 16 lines of text and up to three service lines fit on the screen. In message reading mode, this can be up to 24 lines, depending on the chosen font. For the screen in the settings, you can choose the size and font style, but they do not differ much. Another thing is that, unlike many models, the on-screen font is huge here, it is easy to read from any distance. This is a plus of the device.

Battery

The phone uses a lithium-ion battery with a capacity of 1650 mAh. According to the manufacturer, the battery can provide up to 6.5 hours of talk time, up to 350 hours of standby time. In the conditions of Moscow networks, the device works on average for about one day. The time to fully charge the battery is about 3 hours.

Playing unconverted video is possible for about 8.5 hours. Music playback - up to 30 hours.

Perhaps checking the operating time of the device was the most difficult and voluminous test for me. The number of settings related to energy consumption is huge, and you can customize the phone for yourself, and besides, save time. For each person, this device will be able to show its results, it is very individual and depends on hundreds of settings (screen brightness, number of programs in memory, and so on). Therefore, I decided to conduct comparative tests with the first Galaxy. SIM cards of the same operator were installed on two phones, PUSH mail was configured, the same applications, programs, and so on were also used. In fact, I even tried to call from the same places and talk for the same amount of time. The result turned out to be rather unusual - the Galaxy II's operating time increased from 1.5 to 2 times. In my case, the first Galaxy, starting to work at 9 in the morning, was already completely discharged by lunch (yes, I'm not a very ordinary user, for many it works longer), but the Galaxy II worked for a long time.

I will briefly talk about the settings that are present in the phone and can do a good job in saving energy. First, you should go to the Wi-Fi section and in the advanced settings set up a connection only when the screen is active. This will save some energy, especially if you don't use any IM and want to see information the moment you pick up your phone. Secondly, it is worth considering whether you need PUSH in the mail, if you receive a dozen letters per hour, this function greatly affects the time of work. You can set the interval to 15, 30 minutes or even an hour. This gives a noticeable increase in operating time.

In the screen settings, I recommend setting automatic brightness control, but also adding an analysis of the picture on the screen (a separate item, not available for all competing products). This item allows the phone to choose the brightness depending on the applications used, everything works quite well. Regardless of whether this item is selected or not, the phone has a temperature sensor. If you are in the sun and at the same time playing some kind of toy, downloading a large file at the same time, the screen brightness will automatically decrease so that the device does not overheat. So far, I have not come across such functionality.

The Power Save Mode section allows you to set an assistant that will turn on the power saving mode when the battery is discharged to a certain level. At the same time, you can specify how the phone will save energy. Pretty good customization as it flexibly allows you to set your own priorities. When the battery reaches 15 percent, the camera stops working. The phone is designed to ensure that you can call until the last moment. It's nice that at 15 percent the device lasts 1.5-2 hours, you can talk up to 15-20 minutes.

Surprisingly, the fact is that the Galaxy SII lasts longer than the first Galaxy. And this affects not a slightly larger battery, but the technological platform itself, the Exynos processor turned out to be very economical. In terms of technology, this is an extremely sophisticated phone, in which many settings have been applied, with the help of which real energy savings are possible without compromising the user characteristics of the device. I will hint that by studying the phone in detail and its capabilities, you can save up to 50 percent of the time, which is just great. Other devices do not provide such opportunities in setting even close. And if you also have straight hands, you know how to delve into the insides of the apparatus, then even more. In a word, among the flagships of the latest generation, it is Samsung Galaxy SII that has one of the longest-lasting batteries.

Below are screenshots from Android's built-in utility that shows uptime and power consumption.

USB, Bluetooth, NFC, connectivity

Bluetooth. Bluetooth version 3.0, also called High Speed. When transferring files to other devices that support this technology, Wi-Fi 802.11 n is used, and the theoretical transfer speed is about 24 Mbps. Checking the transfer of 1 GB of a file showed a maximum speed of about 12 Mbps within three meters between devices.

The model supports various profiles, in particular, Headset, Handsfree, Serial Port, Dial Up Networking, File Transfer, Object Push, Basic Printing, SIM Access, A2DP. Working with headsets does not raise any questions, everything is ordinary.

USB connection. In the menu, you can select one of three possible modes of operation: Media Player, Mass Storage, Samsung Kies. It is easy to use the device as a modem by turning on Wi-Fi Hotspot or activating a similar function for USB.

In USB Mass Storage mode, the device is perfectly picked up without additional drivers, you can copy the necessary data. USB version - 2, data transfer rate - about 25 Mb / s.

When connected to a PC, simultaneous operation of USB and Bluetooth is unacceptable, the device requires you to turn off Bluetooth regardless of the current state (whether there is a connection and transmission or not), this is extremely inconvenient. When connected via USB, the device is charged.

The USB on the Go function is supported, which means that using a special adapter, you can connect any flash drives or external hard drives to the microUSB connector, in this case, you will be able to view files in the file manager, copy them, and so on.

The microUSB connector also supports the MHL standard, which means that using a special cable (available from electronics stores) you can connect your phone to a TV (to the HDMI output). In fact, the standard describes the ability to connect via microUSB to HDMI. This solution looks more preferable than a separate miniHDMI-connector on the case.

For GSM networks, EDGE class 12 is provided.

WiFi. 802.11 a/b/g/n is supported, the wizard is similar to that of Bluetooth. You can remember the selected networks, automatically connect to them. It is possible to set up a connection to the router with one touch, for this you need to press a key on the router, and also activate a similar button in the device menu (WPA SecureEasySetup).

WiFi Direct. A new protocol that aims to replace or compete with Bluetooth version 3 (it also uses Wi-Fi version n to transfer large files). In the Wi-Fi settings menu, select the Wi-Fi Direct section, the phone starts searching for devices around. Select the desired device, activate the connection on it, and voila. Now in the file manager you can view files on another device, as well as transfer them. Another option is to simply find the devices connected to your router and transfer the necessary files to them, this can be done from the gallery or other sections of the phone. The main thing is that the device supports Wi-Fi Direct.

NFC (Near Field Communication). The phone has built-in NFC technology, with its help in some countries they create payment systems when you can pay for the purchase with your phone in a parking lot or at a kiosk. Such systems will continue to evolve, and Samsung has built these features into the device to be the most advanced. For some countries, this option will not be available in the menu (Russia is one of them, at the same time NFC is physically present).

Kies via WiFi. Motorola was the first company to offer a phone without the need to download any software to the computer. You connected to a PC using Wi-Fi, in the browser you could view individual sections of the phone. Samsung went a little further and gave access to all sections of the phone. Enter in the browser the address that the phone provides you, and you can work with all your data, download them to your PC. Convenient and simple. No special programs, you can write SMS from your computer, read them and so on.

Traffic control

Individual functions can be controlled using movements. In most cases, these movements are contrived. For example, in the gallery, you can touch the picture with two fingers and, by tilting the device, zoom in or out on the image. It is not always possible to adjust the speed of changing the picture, it is easier to zoom it with your hands. The only convenient feature was unlocking, touch the screen and shake the phone, the lock is removed. There are good tutorials in the menu showing how to work with movements, but to save energy it is better to turn them off.

Memory, memory cards

The phone has 16 GB of internal memory (a version with 32 GB is planned), initially about 14 GB is available to the user. The memory card is visible separately, it is possible to display all folders (both from the memory card and internal). There is a file manager that allows you to copy files both from the card and to it. Memory cards are not hot swappable. We've tested microSD cards up to 32GB and they work.

The amount of RAM is 1 GB, after downloading about 800 MB is free. This is enough for all applications, the phone is one of the best on the market in terms of RAM.

Performance

This is the first dual-core phone from Samsung, and the Orion processor is used inside, which was recently renamed Exynos 4210. Compared to the prototypes, the processor has been changed - it is also dual-core, but the maximum frequency is 1.2 GHz.

Is this solution comparable to NVIDIA Tegra2, which I was able to test in Motorola ATRIX 4G, as well as LG Optimus 2x. Both devices were my main phones for several weeks. I can evaluate the performance only from the user's point of view, since there are simply no programs that use all the possibilities of such an architecture today. Samsung's solution is no less fast than Motorola's or LG's phones. They are perceived on the same level. My impression is extremely positive, this is one of the fastest phones on the market. In a number of situations, the Samsung phone even looks faster, it seems that a lot of work has been done on its optimization.

So, here are the results in the Quadrant synthetic test, the regular Galaxy SII firmware scores about 3000 points, while the competitors fall behind by a significant margin. I want to emphasize that these measurements are speculative, they do not affect the real performance of the device, which depends not only on the processor, but also on the memory, as well as on how the programs are optimized and how stable they are in operation.

In Smartbench2011 (optimized for dual-core processors), the results are just as impressive. At the time of testing, this is the only product that showed the maximum result, as you can see for yourself in the screenshot. Below are the results of the overclocked LG Optimus 2x, but this is not a very fair comparison, since you can increase the frequency on Oxynos to much higher rates (1.8 GHz, to be exact). In the absence of commercial samples of the HTC Sensation, comparing the performance of the two devices is not fair, while the Sensation loses in performance in tests. In the Sensation review, we will compare processors and system performance with the Galaxy SII.

Camera

The model received a new 8-megapixel camera module from Samsung, which is one of the best on the market. However, let's compare it with that of the Sony Ericsson Arc.

Sony has created an EXMOR matrix, which is used in the company's flagship - Sony Ericsson Arc. Countless advertising, marketing materials show the superiority of this matrix in low light conditions, and marketing has hammered into people's heads that this is the ideal solution. Or close to it. Unfortunately, Sony is not the leader in photo solutions for phones; moreover, the company's products are secondary to what Samsung does. This can be seen in simple examples of comparative images.

So, we look at the photo of chrysanthemums without any lighting. The pictures look the same. Here and below, images from the Galaxy SII are located on the left.

Let's take the pencils on the table by the window. Side light, lighting is clearly not enough. Both cameras coped with the work in about the same way, I would not single out the leader.

The laughing Buddha in my office turned out great on the Galaxy, but for some reason Arc raised the ISO to 400 (250 on the Galaxy), and at the same time darkened the picture. It also wasn't very sharp.

The situation with the flash is even worse for Arc, the device just shoots as it should. See for yourself. I tried to take pictures several times, but all the time I got this result.

But in this picture (a rare case!) You can even say that Arc shot a little better. Little bit.

In daylight, bright lighting, the cameras have parity, although not all scenes of the Arc work well. But let me remind you that these are almost ideal conditions, and all cameras work well in them.

Well, a couple more pictures:

I hope this little comparison has shown that Sony's EXMOR is pure marketing, nothing more. A regular, untitled Samsung camera puts EXMOR on both shoulders and delivers the best picture quality in all conditions. I think this is enough to stop once and for all the discussion of Sony Ericsson's marketing bullshit about the excellent quality of the cameras (and yes, the iPhone will use a solution from Sony, which will not be available in SE phones due to the high cost).

There is a small but major change to the camera interface in the Galaxy SII. Now the interface can be both horizontal and vertical, it all depends on how you hold the device.

All settings are shown on a translucent background, which is also pleasing. I will briefly list the main settings.

Zoom digital, 4x, you just need to swipe the screen with two fingers to activate it. Very convenient implementation (pinch to zoom). You can judge the quality of the zoom from the following photos, it is not impressive.

Flash mode - automatic, always on, off.

Shooting mode - Single shot (default), Beauty (filter that hides skin imperfections), Smile Shot (search for and response to a smile), Panorama, Action Shot (pictures of moving people or objects), Cartoon (filter that turns a picture into something like a sketch).

Scene Mode - Portrait, Landscape, Night, Sports, Party/Indoor, Beach/Snow, Sunset, Dawn, Fall color, Firework, Text, Candelight, Backlight.

Shutter speed is adjustable from -2 to +2.

Focusing - autofocus, face, macro.

Timer for 2, 5 and 10 seconds.

Effects - negative, black and white, sepia.

Resolution - 8M (3264x2448), 6.5W (3264x1968), 7M (3072x2304), 5.7W (3072x1856) and lower resolutions.

White balance - day, cloudy, Incandescent, Fluorescent.

ISO - auto, 100, 200, 400, 800.

Also worth noting is metering by point or matrix, automatic contrast, image stabilizer, the ability to set a GPS tag.

Sample photos can be found below:

Video. 1920x1080 pixels (1080p) have been added to the already used resolution of 1280x720. At the same time, the file properties indicate up to 30 frames per second, but the picture looks a little twitchy if you are walking or driving. Constant autofocus is supported, while in difficult conditions the camera cannot always quickly focus on the subject or subject (example with cocktails). But in general, the quality of shooting is quite at the level of other solutions and even better. See for yourself.

The Samsung Galaxy S was one of the best and most popular Android smartphones of the last year due to the optimal combination of features and price. This year it was replaced by the Galaxy S II, which is simply unmatched in terms of technical characteristics. But we are well aware that the quality of the final product is determined not only and not so much by the specifications as by the level of execution. Is the Galaxy S II good enough to rightfully take the place of "king of the hill"?

I remember, in the review of the first Galaxy S, I wrote that the phone looks cheap and frivolous. I won’t be able to make the same claims against the Galaxy S II with all my desire, because over the past year the Galaxy has matured and matured. The shiny edging of the case covered with Chinese silver has disappeared, the smooth back cover covered with green circles has gone nowhere - the new Samsung Android flagship boasts a "radical black" case and a textured back cover. True, according to the sensations, Galaxy S II still falls short of HTC devices: the absence of metal affects. In addition, for my taste, the phone still seems too light for its size.

The screen diagonal in the Galaxy S II has increased to 4.3 inches, due to this, the dimensions have grown compared to its predecessor. In the hand, the device feels like a rather rather big spatula, and even in the pocket of tight jeans it can be a bit cramped, so before buying I recommend to twist it live - in case it doesn’t suit you exactly in terms of overall dimensions. The resistance of the case materials to external influences has improved significantly compared to the first Galaxy S: the entire front panel is covered with ultra-strong Corning Gorilla Glass, which in principle is not scratched, and the pimpled surface of the battery cover well masks all damage and makes them invisible.

Personally, I can't make any claims about the build quality. The case cover, despite the minimum thickness, sits in its place like a glove, does not move when squeezed and does not make any sounds. But the mutual arrangement of the slots for the SIM card and the memory card is inexplicable: to replace the SIM, it is enough to remove the case cover, but to remove the memory card, you need to remove the battery. Usually it's the other way around.

Display

Samsung Galaxy S II is equipped with a 4.3-inch Super AMOLED + display with WVGA resolution (480x800 pixels). Unlike Super AMOLED without a plus, there are three fair sub-pixels per pixel, so the actual color resolution of the screen corresponds to the declared one. As befits an AMOLED screen, the contrast and black levels are amazing. Color reproduction can hardly be called natural, rather it is screamingly saturated, but many people like just such an image. The range of brightness adjustment in the Galaxy S II compared to the Galaxy S has been significantly expanded “down”, now, with a minimum backlight level, it is comfortable to use the smartphone in dark rooms, including reading e-books. Of the minuses, I note the very strange work of automatic brightness control, which often sets the backlight to a minimum during the day on the street, and to the maximum at night in a dark room. In the end, I just turned off automatic adjustment and brought a widget to the desktop for manual brightness control.

Screen when viewed from a right angle...

...and on the side. Notice the color difference

Another disadvantage of the screen is that the color temperature varies significantly depending on the viewing angle. When viewed from a 90-degree angle, the Galaxy S II shows a nice warm picture, but when you look at the screen from the side, it takes on a pronounced blue-green tint. Color rendition also depends on the brightness level: at the minimum brightness level, it is shifted to warm tones, at the maximum - to cold. However, only the most picky users (like me) will surely notice this effect, and for the majority of buyers, the beautiful “acidic” colors and excellent contrast will outweigh all the shortcomings of the display. (By the way, anticipating possible questions, I hasten to inform you that I could not detect any yellow spots or stripes either with the naked eye or with instrumental methods.)

Sound

For me personally, one of the main purposes of a smartphone is to play music, so I always pay great attention to sound quality. And oddly enough, the headphone output in the Samsung Galaxy S II suffered compared to the first Galaxy S. First of all, this concerns the headroom. The fact is that for morning runs I use rather “tight” Philips SHE9500 earplugs, and the Galaxy S in them provided a much higher maximum volume level than the Galaxy S II. Otherwise, I can describe the sound quality as very good: Galaxy S II produces a dense, rich and tasty sound. Detailing is very good: unlike the cheaper models of the Galaxy line, complex instrumental compositions (for example, symphonic music) performed by the Galaxy S II do not turn into a slurred mess. In general, as a phone for a music lover, I would characterize it at 7.5 points out of 10 possible. The sound quality in the conversational dynamics is also very good - the interlocutor's voice sounds lively, with rich overtones. But the speaker through which the call melody is played is very small and rather quiet. When the phone is in the pocket of tight jeans, it is quite difficult to hear the call, only the vibrating alert saves.

Software and interface

Samsung smartphone users are familiar with the TouchWiz shell. The Galaxy S II uses a new version of this shell, numbered 4.0, in the work on which Samsung designers were clearly inspired by the example of HTC Sense. To see this, just look at the default desktop wallpaper, the interface for removing / adding additional desktops, and the design of the clock and calendar widget. In my opinion, such borrowings only benefited the smartphone: its interface has become noticeably more beautiful and more convenient. However, Samsung also has its own finds, for example, a music player, which is much more convenient than the player in all other Android devices (including HTC).

Of the little things worth noting, I would like to note very tight integration with social networks (up to the fact that the birthdays of your Facebook contacts are automatically included in the calendar), the most convenient phone book, the built-in file manager (in this place I traditionally want to say hello to HTC, which here has been stubbornly refusing to pre-install file managers on its phones for three years now) and the full version of the Polaris Office office suite that comes with the Galaxy S II.

Performance, autonomy, heating

Samsung Galaxy S II is equipped with a dual-core Samsung Exynos 4210 processor with a clock speed of 1.2 GHz. This is the fastest mobile processor to date, thanks to which the phone scores in the range of 3400-3800 points in the popular Quadrant Standard benchmark and simply tears to shreds smartphones based on NVIDIA and Qualcomm dual-core processors. The performance of the Exynos-integrated Mali 400MP graphics core also commands respect.

Unfortunately, high performance is inseparable from other, less pleasant things, in particular, high heat dissipation. Galaxy S II heats up, and heats up very noticeably. Under load (for example, in games), the plastic case of the smartphone becomes warm, and the metal frame around the camera module becomes so hot that it is simply unpleasant to touch it. For a month of using the device, I got used to heating and put up with it, but, of course, this is a serious drawback. But the battery life, oddly enough, did not suffer at all. With always-on push-sync email and Twitter account, occasional use of the camera and listening to music for about 3 hours a day, the Galaxy S II is able to confidently hold out for a day and a half. If you take basic battery-saving measures (such as turning off Wi-Fi, Bluetooth, and GPS when not in use), two days won't be uncommon.

Camera

While the Galaxy S had the best camera of any Android smartphone in 2010, the Galaxy S II has the best camera of any Android smartphone this season. Neither HTC Sensation nor Sony Ericsson XPERIA Arc with the vaunted Exmor R module can do anything to oppose it. Of course, the camera shoots best outdoors in sunny weather, but even indoors, the quality of photography remains at an acceptable level. In addition to photos, the phone shoots very decent FullHD-video with continuous autofocus. The advantages of the camera include not only excellent image quality, but also high speed. The camera starts up instantly, focuses quickly and saves quickly, making it ideal for capturing action-packed moments. True, all the raspberries are spoiled by the lack of a dedicated camera button.

In the dry matter

There is no doubt that the Galaxy S II is the "best" Android smartphone to date. It has the fastest processor, the most colorful screen and the best camera, decent battery life - in other words, we have a clear technological leader. If we compare the Galaxy S II with competitors, then an interesting picture emerges. There are only two devices of the same class on the Ukrainian market now - these are HTC Sensation and LG Optimus 2x. The Sensation has a better case and screen, but a worse camera and a slower processor. (I don’t specifically say anything about the Sense shell, since this is a matter of taste.) If we talk about the LG smartphone, then from a technological point of view it has not a single advantage over the Galaxy S II, but it costs much less. But we all understand that a good show is more expensive than money, right? Of course, the phone has its drawbacks, in particular, strong heating. And the Super AMOLED + display in fact turned out to be far from being as good as it is commonly believed. In addition, even in the latest firmware version at the time of writing the review (I9100XXKG1 dated July 5), minor glitches are observed (strange operation of light and proximity sensors, periodic “crashes” of the browser and camera). All in all, considering all the pros and cons, we have decided to award the Samsung Galaxy S II smartphone with our highest editorial award, Editors' Choice. 6 reasons to buy Samsung Galaxy S II:

• unrivaled performance;
• the best camera among all Android smartphones on the market;
• Full HD video recording with continuous autofocus;
• good quality headphone output;
• wear-resistant body;
• preinstalled office suite and file manager.

3 reasons not to buy Samsung Galaxy S II:

• strong heating;
• some features of the Super AMOLED + display;
• a large number of small glitches in current firmware versions.

The Galaxy S II smartphone was released in 2011, far from mobile standards, but still enjoys the attention of users. At the time of release, it was a real flagship: a chic 4.3-inch Super AMOLED Plus matrix with a decent WVGA resolution, a 2-core processor, a brand new Android 2.3 with a good proprietary shell - beauty!

Is this the return of a legend, improved and modernized? At first glance, you can’t say so: the technical characteristics seem to have not changed, the design is the same, even the dimensions have remained the same down to fractions of a millimeter. Today we will figure out what kind of “beast” this Galaxy S II Plus is, whether it differs in any way from the flagship two years ago and why Samsung released it.

Appearance

Deja vu is the first sensation when you take the Galaxy S II Plus in your hands. The smartphone exactly repeats the design of its eminent ancestor. Nothing has changed significantly at all: the “hump” at the bottom of the rear panel, the location and size of the controls, camera, speakers, microphones, even the notch to pick up the cover - everything remained in place.

The only difference from the Galaxy S II is the back panel. In the updated model, it is glossy and made in the style of the Galaxy S III. In the original device of 2011, we recall that the lid is textured. Rough plastic is much more practical than the glossy Galaxy S II with the “Plus” prefix. Fingerprints and any dirt remain on the latter, and all this is clearly visible on a dark surface. "Fingers" are easily erased, but in no time appear again.

When we tested the Galaxy S II, its dimensions were alarming. How: width 66 mm, height 125 mm! Today, against the background of "tablet phones" and other devices with a screen diagonal of more than 4.5 inches, the smartphone looks quite compact. The device fits comfortably in the hand. It does not seem heavy, although, judging by the technical characteristics, the weight of the Plus model is 5 grams more than that of the “progenitor”.

The build of the smartphone is still good. The lid still sits firmly in its place, the buttons are pressed clearly, do not play, they protrude from the case just enough to make it convenient to use them blindly.

Well, the design of the Galaxy S II Plus has not changed, and the material from which the back panel is made has become even worse than the original. Maybe the novelty will surprise you with something else? For example, an improved display, increased performance, or an even more advanced camera?

Display

It's amazing how perceptions change in just a year and a half. It seems that quite recently the screen of the Galaxy S II was one of the best in the smartphone segment, and no one noticed pixelation. In the age of Retina, HD, and Full HD, the resolution of the Galaxy S II Plus is an anachronism. Among models of the middle and even lower price range, 480x800 resolution has become the norm, but you still expect a more modern screen from a new device costing more than $500.

The Super AMOLED Plus matrix will please fans of the "acid" image with bright and saturated colors. Viewing angles are good, with deep blacks and muddy whites present. In general, everything is like in the Galaxy S II.

Camera

At one time, the Galaxy S II boasted one of the best "smartphone" cameras. So far, the pictures taken with this device look decent even when compared with the photos taken with the new flagship models.

Photographed in bright sunlight snow

The Galaxy S II Plus smartphone also received a main 8-megapixel photo module. Most likely, the camera remained the same, that is, not bad. However, in our copy, there were clearly defects either with the matrix, or with software image processing, or both. There is a noticeable pink spot in the center of all the photos, there are problems with white balance and focusing, some shots turned out to be as if they had gone through the muzzle of Instagram.

Functionality

The tested Galaxy S II Plus was running Android 4.0.4, although the device should appear on sale with a more recent Android 4.1. The new current firmware out of the box is a significant advantage over the Galaxy S II, but only if the owners of the second smartphone for some reason do not want to update it to the official Jelly Bean.

The interface and capabilities of the device now resemble or rather. The similarity is in everything from the lock screen with a gurgling soundtrack to some Samsung branded features.

For example, when working with long lists of contacts, email addresses, or messages, you can jump to the top of the list by double-tapping the top of the device. Implemented the ability to zoom in and out of a web page and photo by holding two fingers on the screen and tilting the smartphone. The same principle underlies moving a shortcut to another desktop: the icon itself is held in one place with a finger, and the phone must be moved to the right or left. Another feature is called Shake to Refresh. No, the smartphone's firmware will not be updated by shaking, but the Galaxy S II Plus will be able to find available Bluetooth devices.

The device is also able to track the user's gaze, preventing the screen from turning off. Thanks to the "Direct Call" you can call the subscriber whose contact or message is open on the display without touching the display - just bring the smartphone to your ear.

Some of these features are useful, others are only interesting for a short time for the sake of pampering, others do not always work correctly (like eye tracking, for example).

Performance and battery life

Finally, the first significant hardware difference from its predecessor! The Galaxy S II Plus is based on the Broadcom BC28155 platform with two 1.2GHz Cortex-A9 cores, 1GB of RAM and Broadcom VideoCore IV graphics. The predecessor was based on the Exynos 4210 chip, the specifications of which do not differ from the Broadcom BC28155.

It is currently difficult to compare the performance of the Galaxy S II and Galaxy S II Plus in synthetic tests due to different versions of operating systems and benchmarks. It remains to focus on work in conditions close to reality and subjective impressions.

The capacity of the latter is 1650 mAh. Subjectively, the novelty is more "survivable" than its predecessor. This can be explained by a new version of the OS and, possibly, a more energy efficient processor. In the video playback mode at maximum brightness and with the wireless modules turned off, the smartphone lasted 5 and a half hours. In most cases, with everyday use, the device will need to be charged every one and a half days.
