After revision by Samsung codenames of their devices flagship models received the index S. Everyone knows smartphones of this series, and not so long ago the company began to produce tablets as well. The first sign of steel Samsung devices Galaxy Tab S, which got the best of the composer at the time, and became a full-fledged competitor to the iPad.
One of the main competitors for the Apple iPad
Samsung Galaxy The Tab S2 is a continuation of the series. The tablet received an almost reference display, a powerful processor, modern and a 4: 3 screen format. Recent studies have shown that while in the past, users mostly watched movies, now they mostly read books and browse websites. This is what prompted the developer to create just such a format. So, we present to your attention a review Samsung tablet Galaxy Tab S2.

The manufacturer equips its flagship with only a charger, a USB-microUSB cable for connecting to a computer and a set of documents.
Design
The appearance of the Samsung Galaxy Tab S2 has one recognizable feature that makes it impossible to confuse it with a device from another company: physical buttons on the front. One of them is a mechanical Home button with a built-in fingerprint sensor, and the other two are touch-sensitive. The rest of the tablet is similar to other models. Nevertheless, it is difficult not to pay attention to the desire to inherit its main rival - the Apple iPad.
The Samsung Galaxy Tab S2 is available in two screen sizes - 8 and 9.7 inches. As already mentioned, the aspect ratio is 4: 3, since the tablet is primarily positioned for use in business and for browsing. Samsung decided that it would be better this way, because in comparison with previous years, the recycling model of such devices has changed, and fewer users view multimedia. And the new format adds 20% more space. By the way, the first tablet with such a screen was the Galaxy Tab A (read it).
In addition to the buttons, which are located on the narrow part of the tablet, there is a camera and a brightness control sensor on the front surface. The display of the Samsung Galaxy Tab S2 is framed by narrow bezels, and in the 8-inch model they are somewhat narrower, which makes the device more similar to smartphones. Around the display is a metal frame that gives the tablet a serious look. And from behind it turns into plastic. Rear part covered with soft-touch plastic and has a. It houses the rear camera, which protrudes above the body, the Samsung inscription and some kind of buttons for the branded cover. All connectors are on the sides: on the right are the volume and lock / power buttons, as well as two tightly closed slots for nano-SIM and microSD; at the top - a microphone; and on the bottom are two stereo speakers, a headphone jack and a microUSB port. The left side remained completely free. A 8-inch Samsung modification Galaxy Tab S2 with module cellular communication has an additional earpiece speaker above the display and a microphone on the bottom edge, since it can be used to make calls like through a regular telephone.
The case itself is plastic and very thin, only 5.6 mm. It is the thinnest tablet in the world. Despite its subtlety, the device is very solid and built to last. The details are very tightly fitted to each other, and the body at times seems completely monolithic. By eliminating the use of metal, the weight is only about 390 g for the 9.7-inch and about 270 g for the 8-inch. Therefore, without straining, you can work much longer.
Screen
Samsung has outdone everyone in this area, with the Samsung Galaxy Tab S2's display being the best on the market. The 2048 x 1536 SuperAMOLED sensor with a pixel density of 320 ppi delivers the highest brightness and incredibly realistic color reproduction, while the highest contrast contributes to the display of all the smallest details. Indeed, the sRGB color gamut has reached 100%, making browsing photos and watching videos very comfortable for the eyes.
Thanks to this permission, screen samsung Galaxy Tab S2 has no grain, it can be seen only by looking at the matrix under a magnifying glass. Even small letters are clearly and smoothly read. Viewing angles are the highest, so you can comfortably show some content even in a company. If you are not satisfied with too bright colors of the matrix, there is an opportunity to adjust the profile of the screen. There are four profiles available: Basic, AMOLED Movie, AMOLED Photo and Reading Mode, as well as Adaptive Display that automatically launches the desired profile based on content and conditions of use. You can select any profile manually. Each of them differs significantly in terms of color display, white balance and brightness.
About brightness. The standard indicators of Samsung Galaxy Tab S2 are about 375 cd / m2 and depend on the number of light colors. But it is worth activating automatic regulation and going out into direct sunlight, as the brightness easily rises to 700 cd / m 2. Almost no one has such indicators. In combination with the anti-glare filter, the clarity of the picture and the readability of the screen remain at the highest level anyway.
On top of that, there is coverage from greasy stains, and safety glass... Due to the small thickness, I had to put a thinner coating instead of Gorilla Glass 4. So over time, the screen becomes covered with small scratches, visible only in the world when the tablet is off. They do not affect the work in any way and do not spoil the overall pleasant experience. Indeed, the screen of the Samsung Galaxy Tab S2 is the best in quality, not only by the standards of tablets, but also by most smartphones.
Performance
Responsible for the work of the Samsung Galaxy Tab S2 the most powerful processor Samsung Exynos 5433, first used on Galaxy Note 4 and significantly jumped over its time. It has a huge margin of power and performance, since the 20 nm chipset has 4 1.9 GHz cores, more economical 4 1.3 GHz cores, a Mali-T760 MP6 video adapter and 3 GB of RAM. In addition, the hardware has support for a special technology that allows you to use all 8 cores at the same time. The whole question is which applications will utilize this opportunity. Maybe someone was waiting for a new generation processor, but you are unlikely to use the full resource of this.
Naturally, the Samsung Galaxy Tab S2 device functions just exceptionally, there is not even the slightest hint of slowdown. The menu just flies, the tablet easily reads video files with a resolution of 2K (3840 x 2160), opens documents, allows you to play all modern games at maximum parameters. Various performance tests show results on par with the best smartphones, although they do not always reach for them. But its parameters will be enough for the most demanding user.
Multimedia capabilities
The Samsung Galaxy Tab S2 plays the highest bitrate media with ease and supports many music and video formats. However, not everyone may like the standard player. But it is allowed to download and install anyone from the application store.
The two speakers reproduce all frequencies fairly accurately and have a good headroom, so the sound quality is excellent. So it will be possible to watch videos in a noisy place. Unfortunately, the square format will force you to put up with black bars when watching modern movies on the Samsung Galaxy Tab S2, because most of them are recorded in 16:10 format. In headphones, audio sounds very voluminous and deep, music lovers will be happy. Although hardly anyone will buy such a tablet, focusing purely on sound quality.
Battery and run time
The larger version of the Samsung Galaxy Tab S2 is equipped with a 5870 mAh battery, while the smaller one has a 4000 mAh battery. This is a very good indicator for such a thin device. In addition, power saving mode, screen technology and automatic brightness extend the battery life by up to 14 hours. Average indicators with the included 3G-module - 7-8 hours of continuous work. In turn, the numbers may differ from the frequency of use, such as wireless connection and its stability, the profile of the screen, its brightness level, temperature environment. So for each device, the indicators may differ. Games, in general, are the most voracious energy absorbers, you can achieve a maximum of 7-7.5 hours at minimum brightness. But in general, the tablet will be enough for a day, and when disconnected mobile communications- and all two.
V Samsung settings Galaxy Tab S2 can be activated with a special power saving mode. It regulates running processes, reduces processor power, turns off wireless modules, and with maximum savings, in general, makes the screen black and white. This useful function will allow you to extend the viability of the device in desperate moments.
Camera
The Samsung Galaxy Tab S2 is equipped with an 8 megapixel main camera and a 2.1 megapixel secondary camera. They differ little from those in previous model... The only difference is the improved aperture, which means there is no flash. The auxiliary camera has a fixed focus and performs pretty. It also demonstrates a good picture when making video calls.
The main Samsung camera The Galaxy Tab S2 does not show anything super-outstanding compared to many smartphones, which still significantly outperform tablets. The improved aperture and f / 1.9 aperture do not compensate for the lack of flash when shooting at night. Noises appear in the photo, white balance may get lost, autofocus may not work properly. During the day, the camera boasts good detail and sharpness. White balance works correctly, colors are not distorted, the camera focuses instantly. The menu of its settings strongly resembles the settings of the smartphone of the series of the same name. In general, the camera of the Samsung Galaxy Tab S2 has not yet been compared with the phone, but it is one of the best among the tablet.
In the shop Samsung apps there is an interesting 3D Capture program. With its help, you can create three-dimensional images. It is enough to start the application and, following the instructions, slowly turn the device around the object, then save. Only a few devices have such an opportunity.
Operating system and programs
The device is equipped with the Android 5.0.2 operating system with the traditional Samsung TouchWiz shell, which is almost completely identical to the phone one. The set of programs is almost like a bare Android, however, some proprietary applications are still present. Therefore, you do not have to clean the tablet from software junk for a long time.
The Samsung Galaxy Tab S2 system has a large number of settings, with several proprietary features. For example, the S Finder has been added to help you find a file, application or setting, or Smart Manager, a junk cleaner and accelerator. It also has its own Samsung Apps store. Also preinstalled office suite Microsoft Office Android, allowing you to quickly edit the desired document on the go.
A fingerprint sensor built into the Home button keeps your data safe. When using the function for the first time, the setup wizard will ask you to place your finger on the sensor several times until the drawn fingerprint is complete. Up to 4 prints can be programmed. After that, recognition occurs instantly, just touch the sensor with your finger. You cannot configure multiple user profiles through the fingerprint scanner, but the device has such an opportunity. This is very convenient if the tablet is one for the whole family.
In short, the system interface has been redesigned very cool. Samsung promises to release regular Android updates and Android 6.0 Marshmallow is expected to be released in the second quarter.
Competitors
Sony Xperia Z4 Tablet - Qualcomm Snapdragon 810 processor with Adreno 430 video chip; the device has the best resolution of the front camera - 2.1 MP, a widescreen 10.1-inch screen 2560 x 1600; the amount of memory is the same; the tablet is protected from dust and water.
Apple iPad Air 2 - lower pixel density of the screen (264 ppi), 2-core processor, front camera only 1.2 Megapixels.
Considering that Sony's tablet was released later, it's not surprising that its screen resolution is slightly higher. Although you shouldn't forget about the larger diagonal and wide format. The iPad, on the other hand, loses in almost all respects. We can safely say that the Samsung Galaxy Tab S2 is perhaps the best flagship device today.

Conclusion
Surely everyone will agree that Samsung has managed to set the tone in tablet fashion and the bar that many will seek to jump over. The price, however, is too expensive for many, but that is why it is the flagship. Its superb performance, high-quality screen and strong battery will delight both gamers and those who buy a device for work.
Are you planning on purchasing the Samsung Galaxy Tab S2? Does everything suit you? We will be glad to see your comments after reading the article.
And in this review we will look at the younger model of this family - Galaxy Tab 2 (7.0), which has a 7-inch display, but the differences between the two tablets do not end there. So, first things first.
The Samsung Galaxy Tab 2 is very similar to its predecessor, the P1000, from the Galaxy Tab line of tablets. But it is worth noting that the thickness has decreased, now it is only 10.5 mm, and the surface from a smooth gloss has turned into a matte gray plastic. The height and width of the device are 193.7x122.4 mm, and the weight is only 344 grams. Despite the relative lightness of the device, it is very convenient to hold it in the hand.
On the front side there is touchscreen, and on the back - the "peephole" of the camera.
The assembly is done at the proper level - there are no backlashes and creaks during operation.
Performance, operating system and applications

Introduction
Last year, the South Korean company introduced two models of tablets to the market in the operating room. Android system from the Galaxy line - Tab 8.9 and Tab 10.1. Tab 2 7.0 and Tab 2 10.1 were shown this year. At the presentation of tablets, almost all journalists were interested in the main differences between "old" devices from "new" ones. I think the same question will arise among potential buyers of Samsung products. Therefore, I will try to briefly explain the difference between Tab 10.1 and Tab 2 10.1.
Firstly, in order not to conflict with Apple once again, Samsung slightly changed the design: this time, speakers appeared on the front panel, on the right and left. Secondly, the “second” Tab got a slot for a memory card, which was clearly lacking in the previous model. Thirdly, instead of a chipset from NVIDIA, they installed a chipset from Texas Instruments - from my point of view, the solution is correct. Fourthly, both Tab 2 7.0 and Tab 2 10.1 are able to make calls out of the box. What I didn't like was the lack of autofocus on the camera. "First Tab" with Wi-Fi costs from 16,000 rubles, with 3G - from 20,000 rubles. "Second Tab" with Wi-Fi - 15,000 rubles, with 3G - 20,000 rubles.
I think that whatever one may say, the new models look a little more advantageous, if only because of the slightly lower price and the presence of a microSD slot.
Design, dimensions, controls
Unlike previous version, which strongly resembled an "apple" gadget, appearance the front side of "Taba" 2 was slightly altered: now a thin semi-gloss strip of dark gray passes along the edge, and on the sides there are speakers covered with a metal mesh. The back is made of matte light gray plastic.
Dimensions Tab - 256x175x8.6 mm, and weight 565 grams; Tab 2 is 256x175x9.7 mm and weighs 588. As you can see, the new product has become a little thicker and heavier. It is possible that this is due to the installation of two speakers on the front. For example, the dimensions of the iPad3 are 241x185x9.4 mm, and the weight is 662 grams.
The build quality, as always, is at its best: nothing backlash, no creaks, the back cover does not bend. Since the materials are generally non-staining, fingerprints and other marks only remain on the screen and are relatively easy to wipe off. Unfortunately, I haven’t noticed any covers among the accessories for the P5100, since most likely it will not fit from the P7500 - there are no cutouts for the speakers.
The front panel houses the front camera and light sensor. The latter responds quickly and smoothly adjusts the brightness level of the screen backlight. The power button, volume rocker, microSD slot, standard 3.5 mm audio output and a slot for a regular SIM card are located on the top end. At the bottom there is a microphone and a proprietary Samsung connector. On the back of the device is a camera.

Display
The diagonal of the screen is 10.1 inches (physical size 217x127 mm), the resolution is the same as on the Tab 10.1 - 1280x800 pixels (150 pixels per inch), displays 16 million color shades, the matrix type is PLS-LCD (one of the varieties of IPS-matrices - Plane to Line Switching), sensor type - capacitive with support for up to 10 simultaneous touches. The sensitivity of the touch layer is excellent. The screen is virtually scratch-resistant with a tempered glass (not Gorilla Glass) coating.
The viewing angles are maximum, but when the P5100 display is tilted, the image acquires a slight purple tint, and the brightness drops slightly. It can be adjusted either manually or switched to auto mode as there is a light sensor on the front of the tablet. It is high, but somewhat inferior to the Apple tablet. The brightness control range is large: you can set it very low, at which it is comfortable to watch a movie or read a book at night.
Unlike previous models, in the Tab 2 10.1 settings there is no "Screen Mode" item. But there is a choice of style and font size (small, small, regular, large, huge).
The display fades in the sun by about 50%.

Battery
Samsung Galaxy Tab 2 10.1 is equipped with a 7000 mAh lithium polymer battery. The manufacturer claims that a full charge should last up to 10 hours of talk time and up to 2000 hours of standby time. These numbers are close to what I got in practice. For example, when playing movies at maximum brightness and outputting sound to the headphones, the battery lasted for 7 hours. In general, good data autonomous work tablet: in "normal" use mode (automatic brightness of the backlight, 3G-Internet about 3 hours and the same amount of Wi-Fi, watching an hour and a half movie and two hours of listening to music on the speakers, as well as taking pictures for about one hour) P5100 worked for almost 8 hours. Even under maximum load (high brightness of the backlight, games, performance tests, etc.) the battery ran out after 6.5 hours.
The tablet does not charge from USB (a red cross is drawn on the battery indicator icon), and this is logically understandable: the huge capacity of the battery can be "filled" with a small current all day, and it will take about 3.5 hours from the mains.
There are several points in the energy saving section:
- CPU. Limit maximum performance
- Screen. Use low power for the screen
- Background color. Change background color in e-mail
Below is a brief description of each item. For a couple of weeks of using the tablet in this mode, I found out that there is not much difference between the enabled and disabled power saving function.
Communication capabilities
The tablet works in 2G (GSM 850/900/1800/1900) and 3G networks (HSDPA 850/900/1900/2100). HSDPA + speeds up to 21 Mbps, HSUPA up to 5.76 Mbps. It is now possible to make calls out of the box. The sound can be transferred to a wireless headset.
In the presence of a complete "gentleman's" set: Bluetooth version 3.0 with support for A2DP stereo profile, Wi-Fi standards a / b / g / n (Dual-band) with the ability to "distribute" the Internet (access point "Wi-Fi Hotspot") and USB 2.0 (proprietary connector).
For additional accessories, for example, a USB hub, keyboard or mouse, special adapters are sold. Yes, not very convenient, but Samsung, alas, followed in Apple's footsteps.
During the whole time of testing, there were no problems with networks.
Memory and memory card
The device has 1 GB of RAM, about 700 MB are available, of which about 400 MB are free. Internal Flash-memory - 16 GB (only 4.6 GB is displayed in the settings). The write speed reaches 15 MB / s. There is a slot for a microSD memory card (up to 32 GB).
Camera
V Galaxy tablet Tab 2 10.1 has two camera modules: front - 0.3 MP with a large depth of field, main - 3.2 MP without autofocus and flash. Let me remind you that in the previous model, the front camera was 2 MP, the main one had autofocus, and there was also an LED backlight.
The main camera is not bad. Maximum resolution up to 2048x1536 pixels. The color reproduction is natural, the white balance is almost perfect, the picture clarity is satisfactory. The photographed text from A4 sheet can be made out.
Movies are recorded in 720p (1280x720 pixels) resolution at 30 frames per second.

Performance
This is where the main changes took place. Samsung has abandoned the NVIDIA Tegra 2 chipset and installed a chipset from the American company Texas Instruments - OMAP 4430. The technical process is 45 nm, the CPU instruction set is ARMv7, and the graphics accelerator is PowerVR SGX540. The processor is a dual-core Cortex-A9 with a clock speed of 1 GHz. The chipset belongs to fourth generation OMAP, which contains IVA3 hardware multimedia accelerator with programmable DSP, which can encode / decode 1080p Full HD video.
Software platform
The tablet works on one of latest versions Android ICS - 4.0.4. The firmware version is P5100XXLE3, the kernel version is 3.0.8-583334-user, the build number is IMM76D.P5100XXBLE3. More details with Google android Ice Cream Sandwich you can check out. Samsung's own TouchWIZ is used as the shell design. It must be said that the UI has not yet been "cured" of slight slowdowns while flipping through virtual screens. Frankly speaking, it is no longer funny - this has been going on since the first versions of TouchViz on tablets, and they still cannot fix the obvious bug. Interestingly, any other shell behaves perfectly, be it Yandex.Shell or Go launcher.
Navigation
The tablet is equipped with a GPS navigator. Its characteristics are the same as those of most "pills". For all the time of working with him, there were no problems. “Addresses”, “Maps”, “Locator” and “Navigator” are installed as applications for joint operation with GPS.
Messages and calls
From the device, you can send messages and make calls in the same way as from a regular smartphone. A standard Samsung keyboard is used to enter text. The language is switched by pressing the globe icon. Voice and handwriting inputs are available. The keyboard has a separate button for launching the clipboard.
The dialer is huge, it appears from the bottom when the tablet is in vertical position and to the right when it is landscape. The telephone part contains several tabs: "Keypad", "Journal", "Favorites" and "Contacts". Almost all items contain the same functions as in the "old tablets". By the way, the slot for the SIM-card is ordinary, i.e. not currently fashionable microSIM. There is a vibration signal.
As you know, Samsung has updated a couple of its base tablets with a diagonal of 7 and 10 inches, focusing on redesigning and reducing their cost, as expected, saving on the hardware platform (TI OMAP 4430 was used last year Amazon Kindle Fire). Thus, those who want to get the most productive solution and additional functionality should pay attention to, while the considered Samsung Galaxy Tab 2 10.1 (P5100) more suitable for those looking for a solution with a balanced price / equipment ratio.
Design
Samsung Galaxy Tab 2 10.1 has dimensions typical of 10-inch models, 9.7 mm thick and weighing less than 600 grams. The tablet comes with a typical package consisting of an instruction manual, a proprietary cable and a network charger with detachable plug.
The front panel of the tablet is almost completely covered with tempered glass, which protects the 10-inch PLS-matrix from damage. The lower part of the glass is decorated with the manufacturer's logo, the upper part hides one of the two cameras and the light sensor.
In contrast to the traditionally minimalistic design of the main panel of tablets, here you can find side inserts made of gray glossy plastic and a pair of multimedia speakers hidden under metal false grilles. As a result, confuse Samsung Galaxy Tab 2 10.1 with any other tablet, when looking in full face, it will no longer work.
Connectors, controls
Front bezel Samsung Galaxy Tab 2 10.1 made of gray glossy plastic smoothly passes to the sides of the case, and in the area of the upper edge it even “wraps” around the back panel with a characteristic flap.
The short edges of the body are completely free, only the microphone and the proprietary connector are placed on the lower edge, but the upper edge is literally littered with useful elements. Here you can find the power button, volume rocker, standard audio output, as well as slots for SIM and microSD cards.
Rear panel Samsung Galaxy Tab 2 10.1 made of silvery plastic with a matte surface, which outwardly is almost indistinguishable from aluminum. However, upon closer acquaintance, the plastic betrays itself as less rigid and lacks the coolness characteristic of metal. On the rear panel you can find only the company logo, service data and the simplest main camera of 3.2 megapixels without autofocus and flash.
Screen
Tablet Samsung Galaxy Tab 2 10.1 equipped with a 10-inch screen with a resolution of 1280 by 800 pixels, made using PLS technology, which provides a sufficiently high-quality image from any viewing angle. Capacitive multitouch recognizes up to 10 simultaneous screen touches.
Display backlight brightness Samsung Galaxy Tab 2 10.1 adjustable from 5 to 270 cd / m2, the “half” value of the adjustment slider gives a brightness level of 160 cd / m2. The work of the automatic brightness adjustment system pleased high speed reactions.
Functionality
Samsung Galaxy Tab 2 10.1 built on the TI OMAP 4430 dual-core gigahertz platform and equipped with 1 GB of RAM. The tablet works under Android OS 4.0, supplemented by Samsung's proprietary TouchWiz add-on.
The built-in memory is 16 GB, of which less than 12 GB is available to the user. You can expand the storage capacity by an additional 32 GB using microSD cards... From a 7000 mAh battery, the tablet can work for about 8 hours under mixed load. The presence of not only Wi-Fi, but also a built-in 3G-module allows you to use Samsung Galaxy Tab 2 10.1 for voice communication.
Tablet Samsung Galaxy Tab 2 10.1 runs Android OS 4.0.4 with Samsung TouchWiz add-on. In addition to the redesigned interface, this shell adds a convenient rotating panel with a set of useful utilities.
The speed of the system is satisfactory, but at active work the interface sometimes “thinks” for a moment. The system is preinstalled with several very useful applications and several games, so full use Samsung Galaxy Tab 10.1 you can start right after unpacking it.
