In mid-June in New York, the world premiere line of tablet Samsung Galaxy Tab S with larger screen sizes, the main feature of which is the use of technology Super AMOLED. What else besides a steep display can boast these new items?
Speaking of that line Tablets Galaxy Tab S received the world’s first active-matrix screens OLED Super AMOLED (Active-Matrix Organic Light-Emitting Diode) large diagonals (8.4 and 10.5 inches), Samsung Electronics does not disingenuous. First, the tablet Galaxy Tab 7.7, were born in 2011, went to the smaller 7.7-inch display, and, secondly, he was executed by a particular technology – Super AMOLED Plus.
Recall that with the addition of the word Super AMOLED displays in the air gap disappeared between the sensor layer and the matrix, which increased brightness, reduce the reflection of light (almost 5 times), reduce energy consumption and the thickness of the device. Such screen in 2010 equipped with, for example, the smartphone Samsung Galaxy S.
In advanced technology Super AMOLED Plus arrangement with two subpixels PenTile RGBG, based on the features of the physiology of the human eye, has given way to traditional, with three sub-pixels RGB. That is, if in the first case, each point in the image consisted of sub-pixels of red and green, or blue and green, in the second – three (red, green, and blue), as in conventional LCD displays. “Plus” Super AMOLED Plus screen has been the increased brightness and energy efficiency, as well as clearer and less grainy. This technology debuted in the display of the smartphone Samsung Galaxy S II. In the same plates used new technology Super AMOLED screens for high resolution.

Ergonomics, design
Design Galaxy Tab S flagship got already much he resembles an increase in size (or fell under the rink) smartphone Galaxy S5. On the front panel immediately struck mechanical oblong button “Home”, and a rear dominates branded “perforated” texture. Unlike the Galaxy Tab 7.7 back cover of the novelty is not aluminum and plastic. With no soft-touch coating, such as a camera phone Galaxy K Zoom, but simply matte plastic (well at least not glossy). Along perimeter passes golden rim under metal – decoration except for an amateur.
One-handed tablet biggish – makes itself known 8.4-inch screen. But, nevertheless, the new thinner (6.6 mm vs. 7.2 mm) and lighter (294 g versus 331 g) than the display receives the same size, Galaxy Tab Pro 8.4. This is also true with respect to the 7.9-inch “style icon” – Apple iPad mini with a Retina-display – (6.6 mm vs. 7.5 mm) and (294 g versus 331 g), respectively.
On the front panel (in portrait orientation tablet) placed above the screen light sensor and front camera lens. Major mechanical key “Home”, with built-in fingerprint scanner it is surrounded by two touch – “Back” and “Recent Applications”.
Left edge body is completely free, but may download power button / lock, volume rocker, an infrared port and a slot to plug the memory card microSD.
At the upper end provided an opening for the microphone and stereo speakers grille. For the second speaker grilles, connector 3.5mm for audiogarnitury microUSB and took the lower end of the housing.
On the rear panel, decorated with the logo of Samsung, taking the place of the holes in the main camera lens and flash.
Noteworthy are two special latches similar to the buttons that are needed exclusively for corporate cover Book Cover or cover Simple Cover. In particular, Book Cover allows you to place the plane of the plate relative to the surface at certain angles, for example, watching movies (60 degrees), to work on the Internet (about 30 degrees) or for typing (about 10 degrees). It is unclear, however, why did such a tricky fixture and not catered to developers than conventional magnets.
Case edges are not sharp, so if you manage to embrace the tablet with one hand, the inconvenience in this sense it does not deliver. In the power button / lock and volume rocker and a small course elastic are pressing.
Screen, camera, sound
Undoubtedly, the main asset is its novelty screen. Indeed, at 8.4 inches diagonally, he has 2560×1600 pixels, in other words, WQXGA-resolution (Wide Quad eXtended Graphics Array) at a ratio of 16:10. Recall that this “broad” version of QXGA (4:3), which is 4 times more pixels than the WXGA (1280×800, 16:10). Thus, the density of pixels per inch (count the green subpixels) is 359 dpi.
But it’s still half the battle. As already noted, the display uses Super AMOLED-matrix. Recall that, for example, Galaxy Tab Pro 8.4, which debuted six months earlier, received a screen of the same size and with the same resolution. Only now he had matrix TFT LCD (Super Clear LCD). This means that not only new items increased viewing angles, but the colors are brighter and deeper blacks. Indeed, the contrast can reach 100 000:1. In Samsung also said that coverage Adobe RGB color space is more than 90%, while in conventional LCD panels – about 73%. Juicy and bright image on the screen is really impressive. By the way, the small thickness of the tablet is largely due to the lack of backlight module unnecessary for Super AMOLED-display. It should be borne in mind that the PenTile schemes because very small fonts will look less clear than, say, a conventional LCD screen Galaxy Tab Pro 8.4. However, to learn about it at this resolution is likely to need a magnifying glass.
Adaptive screen that runs on the main interface and some applications (including the “Video”, “Gallery”, “internet”, “camera”, etc.), not only automatically adjusts the brightness, but other settings, depending on the ambient light, as well as how to use the tablet. Manual adjustment of color scale allows you to choose a comfortable color reproduction. In addition to the main mode available two – “AMOLED Cinema” and “AMOLED Photography.” The touch screen supports multi-touch tablet, with AnTuTu Tester program and MultiTouch Tester showed that recognize up to ten simultaneous keystrokes. For use with gloves in the settings the option of increasing the sensitivity of the screen.
Typically, the camera plate is used for random pictures or fotozametok, and therefore she is not given much importance. But in this sense, Galaxy Tab S 8.4 lucky he perepal pretty decent 8-megapixel unit with autofocus and flash. Last in the plates is not as common, moreover, suggests its use and as a flashlight. Maximum frame size at a ratio of 4:3 (8 MP) is 3264h2448 points, while 16:9 (6 MP) – 3264h1836 points. Skip to main shooting mode to “Auto” and added “Retouch”, “Panorama” tint “,” Two-way Recording “and even somewhat mysterious” Sneem. And so forth. “(It turns out; it creates a series of images that are improved with the available effects.) In the settings you can select the picture size and resolution of the video include stabilization (photo / video), to determine the white balance, exposure value, and so on the volume rocker easily assign responsible for the shutter, start a video or digital zoom (4x). Onscreen buttons frequently used settings in your comfortably bear (or disappear again) in the upper part of the screen (shortcut menu), where the default settings are icons, flash and change camera. Examples photos can be viewed here (DropBox).
Directly from the application interface “camera” has a photo editor “Gallery.” Still, you can rotate, crop, change brightness, contrast, saturation, temperature, exposure, and also to impose effect (“Sepia”, “Vintage”, etc.) or the appropriate sticker, opt for a picture frame and even something to paint on.
Intended purpose of the front camera, which added a 2.1-megapixel sensor – is video calling and “crossbows”. Therefore, the main mode here, of course, “Retouch”, which improves the complexion. The maximum resolution for self – 1920×1080 pixels (16:9), and the classical aspect ratio (4:3) – 1440h1080 points. Note that both cameras are able to record video in Full HD-resolution (1080p) with the speed of 30fps. All video content is stored in a file container MP4 (Video – AVC and audio – AAC).
Incidentally, the sound from the built-in stereo speakers appeared, surprisingly, not only loud, but fairly clean. Well, not Hi-Fi, of course, but to listen to music, and even more so to watch a movie, you can quite comfortably and without headphones.
Filling performance
Under the hood, Galaxy Tab S 8.4 was “native” chip – Samsung Exynos 5 Octa (5420) architecture big.LITTLE GTS (Global Task Scheduling), consisting of eight processor cores, four of which – Cortex-A15 1.9 GHz and another four – Cortex-A7 1.3 GHz. Recall that architecture big.LITTLE GTS, providing so-called heterogeneous multiprocessing HMP (Heterogenous Multi-Processing), allows the use of all cores simultaneously. Graphics Exynos 5 Octa (5420) takes care of Mali-T628 MP6 (533 MHz) with six execution units. It is worth noting that the tablet is on board the flagship RAM 3 GB. Such a configuration of “iron” should cope with virtually any task, including “heavy” games. Discrepancies may be associated mainly with the software under unadjusted 8-core processor architecture.
On synthetic AnTuTu Benchmark test tablet was 32 359 “marks”, followed by the comment “amazing.” At least last year’s flagship Galaxy S4 (27 435), it is easy to beat. Recall that, for example, LG G Pad 8.3 earned on this test all 22,656 “virtual birds.”
On the benchmarks Vellamo, tablet ahead again Samsung Galaxy S4 in the CPU test Metal (1380 vs. 1256), but on a multi-core test Multicore could boast only a victory over the “standard” of the 7-inch tablet Asus / Google Nexus 7 (1558 vs. 1395).
Average frame rate on visual test Epic Citadel with variable settings High Performance and High Quality (performance at the expense of quality and vice versa) differ only in the sign of the decimal point – 55,8 fps and 55,0 fps, respectively. Even at the highest possible mode (Ultra High Quality) its value has decreased to only 43,4 fps. However, the program displays a picture as seen from the figures in the screenshots, just resolution HD.
Tablet showed themselves quite well on the universal game benchmark 3DMark, and on the results of the most advanced test Ice Storm Unlimited, the company was in the “fellow” with a processor Exynos 5 Octa, including Galaxy Tab S 10.5 and Galaxy Note Pro 12.2.
16 GB of internal memory in the declared Galaxy Tab S 8.4 is available about 11.5 GB free but a little more than 10 GB. Card slot microSD support media such microSDXC up to 128GB. In addition, thanks to the addition USB-OTG can connect to your phone and even ordinary flash drive. “Cloud” storage 50 GB of DropBox fall to the owner of the tablet for 2 years only.
Wireless communications are 2-band Wi-Fi a / b / g / n / ac (2,4 and 5 GHz), Bluetooth 4.0 and infrared, which is useful to control home appliances.
Results of the program AndroiTS GPS Test suggest that navigation and positioning will help the American, Russian and Chinese satellites (GPS, GLONASS, Beidou).
Galaxy Tab S 8.4 got lithium-polymer battery with 4900 mAh, which is only slightly beat in capacity battery Galaxy Tab Pro 8.4 (4800 mAh). Note that the Super AMOLED screen has an impact on energy consumption of the tablet as an abundance of dark scenes it does not waste energy on “black” pixels. Manufacturer stated 11:00 watch the video, at the same time at full brightness videos in Full HD-quality continuously spinning a little over 7 hours (screen mode “AMOLED Cinema”).
On tests AnTuTu Tester 2.1 battery Galaxy Tab S 8.4 has earned 10,163 points, surpassing, in particular, the 5.7-inch Galaxy Note
tablet3 (SM-N900) with Super AMOLED-screen (Full HD) and the battery on 3200 mA * h However, the program has been able to detect and, therefore, loading, only four of the eight core processor.
In the conventional power saving mode to save battery, among other measures, the colors on all screens can be changed to grayscale. As in the flagship Galaxy S5, has extreme power saving mode, which significantly limits the functionality of the tablet, but it helps to stay on a single charge as long as possible.
Software
Tablet running Android 4.4.2 (KitKat) with the original shell of the last generation TouchWiz interface Magazine UI. Of the program “chips” Galaxy Tab S 8.4 in the first place it should be noted feature fingerprint, which developed out of the scanner, built-in mechanical button “Home” (as in the Galaxy S5). Note that the Galaxy Tab S 8.4 of the first tablet was such a scanner. There are three scenarios for using prints: to lock the tablet, check your Samsung account and paying through PayPal.
The first thing you need to register information about the prints, which should not hold, and drag your finger on the button. Each finger is repeated 8 times. At the same time, in multiplayer mode, each of the eight possible contenders for the tablet can save 3 prints.
Also of interest are applications for remote management – SideSync 3.0 and RemotePC. So, Sidesync 3.0 synchronizes Galaxy S5 and Galaxy Tab S 8.4 via direct connection Wi-Fi, allowing, for example, a phone call can be redirected to the plate.
But with the help of application RemotePC, which appeared in the Galaxy Tab Pro, access to another computer easily accessible via the Internet. To do this, from a PC or laptop must first go to the site and download from there remotepc.rview.com program-agent, and then to use it to establish a connection. But above all, you want to have an account Samsung.
Resume
On the one hand, Galaxy Tab S 8.4 clearly the leader and claim to be a flagship position. It is lighter and thinner than its competitors, it has the largest amount of RAM and the maximum capacity supported microSDXC-cards. Do not forget about the fingerprint scanner. And, of course, the main advantage of new items – Super AMOLED screen with high resolution.
On the other hand, a dull plastic case, even without the soft-touch coating, frankly disappointing. And from the runtime I would like something more, so to speak, the flagship. With this in mind, the initial price for the tablet seems to be somewhat overstated.
Outcome of the review of the tablet Samsung Galaxy Tab S 8.4
Pros:
• Great Super AMOLED-display
• Slim and lightweight body
• High performance
• Fingerprint Scanner
Cons:
• Non-original design with an abundance of plastic
• High initial price
