However, the most interesting thing in the Samsung Galaxy Tab S 10.5 - is its screen. Super AMOLED-display ensures a bright, juicy image, high contrast and viewing angles that are simply dazzling. Also, such a display, on average consumes less power than a typical LCD-display, which increases the battery life of the display, but it also has its own characteristics. Not without its drawbacks of this technology, Samsung Galaxy Tab S 10.5 «stretching the truth 'with colors, they get too busy. Although the manufacturer and added the ability to select different display modes, it is only partly solves the problems with color reproduction. However, for such viewing angles and contrast of the display can be forgiven everything. However, it remains unclear why all the same need as wide viewing angles, in practice, to whom and what to show at such an angle?
In general, we recommend Samsung Galaxy Tab S 10.5, if you do not mind the price, or you're not waiting for the new Apple iPad.
Materials and design
More recently, Samsung released Samsung Galaxy Tab Pro 10.1, similar to the Samsung Galaxy Tab S 10.5 characteristics also appeared and Samsung Galaxy Tab 10.1 4. In this connection the question arises - how to distinguish the appearance of these models? In the case of the Samsung Galaxy Tab S 10.5 tablet have grown slightly diagonal, visually it has become much thinner. To our surprise, despite the very thin chassis, it is durable and does not bend, not crunches and never play. As always, the body is made up of plastic, glossy front and matte back slip.
Appearance is not so very different from the typical tablet Samsung, except that its shape became slightly more rectangular, the edges are the same under the metal edging. To distinguish the front panel Galaxy Tab S 10.5 of the Galaxy Tab Pro 10.1 is almost unreal: the same buttons, sensors, and everything else. In order to distinguish, you have to look at the back of the tablet: on Tab Pro 10.1, it is made under the skin, while the Tab S 10.5 is perforated in the spirit of the smartphone Samsung Galaxy S5. In general, Samsung products can be easily confused.
Observant users will also notice the round "buttons" on the back of the body, they are necessary for the firm to cover the plate. Of note the unusual and the fact that the 10-inch model micro-USB connector is not at the bottom and right, that kind of a departure from the "canons". On the upper parts of the side faces of the tablet is the speaker, and the power key and the volume are at the top. I must say that to reach for it is not very convenient, but it looks like the best place for them is not there. Tablet Samsung Galaxy Tab S 10.5 can be purchased in black and white.
Dimensions and weight
Samsung Galaxy Tab S 10.5 turned out light and thin device, by the standards of 10-inch tablet. Interestingly, the previous Samsung Galaxy Tab Pro 10.1 was slightly heavier and thicker than Apple iPad Air, as announced in less than six months, Samsung Galaxy Tab S 10.5 is already thinner and lighter: 468 grams and 6.9 mm versus 475.5 grams and 7.5 mm at the iPad Air. The difference in thickness is palpable, and the weight will hardly be noticeable to someone. Diagonal tablet is great, so normally use it with one hand is difficult. From the ratio of length and width, the body of the new Tab S became a little less elongated than the Tab Pro.
Ports and interfaces
As regards ports and wireless interfaces, there are no revolutionary changes, but still at a high level. Top located infrared port on the left side are now only audio jack and speaker at the bottom is now empty, and the right are micro-USB 2.0, the remainder of the speaker, slots for memory cards and Micro-SIM. It supports memory cards up to 128 GB. As befits a premium device, USB-connector supports MHL to transmit high-resolution video. In the list of Wi-Fi standards have high-speed 802.11 ac, more modern version of Bluetooth 4.0 with A2DP support and low power consumption. Also the tablet has a LTE-modem (if you purchased the Wi-Fi version), GPS with support for A-GPS and GLONASS with the opportunity to work with the Chinese satellite BeiDou, but no NFC chip. Compared with the iPad Air, Samsung Galaxy Tab S 10.5 is allocated an infrared port and support for high-speed Wi-Fi 802.11 ac, compared to the Tab Pro 10.1 No significant change. This time the confusion with the processor model tablet Samsung Galaxy Tab S 10.5 will not happen. Both models SM-T800 (Wi-Fi version) and SM-T805 (LTE-version) have 3 GB of RAM and equipped with the same 8-core processor Exynos 5 Octa 5420 (4 cores at 1.9 GHz, and the remaining 4 to 1, 3 GHz). The same processor is used in more Samsung Galaxy Note 3 and Samsung Galaxy Note 10.1 2014 Edition. Built-in memory - 16 GB or 32 to choose from, while safely subtract several gigabytes occupied by the system and preinstalled software.
Performance
| Chipset : | Exynos 5 Octa 5420 |
| Number of cores and frequency : | four core, 1.9 GHz + quad-core 1.3 GHz |
| Memory : | 3 GB |
| Built-in memory : | 16/32 GB |
| Graphics processor : | Mali-T628MP6 |
The tablet was a good benchmark for the performance of the processor, but with graphics, in our opinion, could have been better: Mali-T628 MP6 sometimes retarding in graphically demanding games at the highest settings, probably because of the ultra-high resolution display or the best optimization operation. By the way, this Apple iPad Air and there was not, but it has lower resolution and you can not configure anything in games. Samsung Galaxy Tab S 10.5 loaded pretty quickly - about 20-23 seconds. We also want to measure the load time of the first level in NOVA 3, but the game is suddenly not supported on the device. In addition, the benchmark is not Epic Citadel is run in native resolution, as Tab S 10.5, and the Tab S 8.4, only 1280 × 800 pixels, which can be seen even on the eye: pixels make their way here and there, and the edges of objects, not to mention the fine print begins to blur. In synthetic tests Samsung Galaxy Tab S 10.5 showed good results. In our tests, each of which was carried out on several occasions, is the average of the five iterations. The benchmark Geekbench 3 tablet showed good results - 2782 points in the Multi-Core benchmarks that at one level, but slightly lower than that of its predecessor and iPad Air with his 2840 points. Basemark OS II praised Galay Tab S 10.5 to 831 points, which is very good. Tests on the SunSpider took tablet surprisingly long time - 1007 milliseconds have iPad Air, we received an average of 387 milliseconds, which is much faster. It is surprising that while the 8-inch Tab S 8.4 is stable in the test showed a much better result - an average of 462 milliseconds.
In browser benchmark Google octane v2 tablet received 4086 points. In the graphic chip results slightly above average - 14 fps in the test T-Rex HD Onscreen on benchmark GFXBenchmark, which is very bad if sranivat competitors and iPad Air and Sony Xperia Z2 obtained the best results, even Dell Venue 8 9 thousand rubles received in this test, 16 fps, and overtook the unfortunate Samsung Tab S 10.5. In the test of the Ice Storm Unlimited 3D Mark - 13456 points. Overall, the results of synthetic tests are good, but lower than that of its main competitors, and on many points, even their predecessors. With daily use Samsung Galaxy Tab S 10.5 can slow down a little bit, if you open several windows in multitasking mode, some games at the highest settings the graphics or animations embedded in Web pages. And according to our tests, it can easily suddenly unresponsive, which did not expect from the tablet for the price.
Display
The most unusual in the tablet Samsung Galaxy Tab S 10.5 - Super AMOLED-display with a resolution of 2560 × 1600 and higher ppi to 288 ppi. The density of pixels per inch is slightly higher than the Apple iPad Air with its 264 pixels per inch. Unlike the Samsung Galaxy Tab S 8.4, the scheme is not applicable Pentile, ie sub-pixel here is not saving. In our tests the screen performed well, but strange, at first glance, the results. The display, of course, supports multi-touch input at a high level. The result of the maximum measured brightness, if you put a solid white background - low, only 296 cd / m2. However, the visual image is very bright, brighter than most tablets tested, it can even be used as a good night lamp. Perhaps there is a feeling because AMOLED-layer displays no backlight, it LEDs emit light themselves, and in conventional LCD-liquid crystal displays need a separate layer highlight illumination. Apparently, here and receive the difference in the visual perception and indicators, measuring instruments. This fact leads to the display thinner, because there does not need just a layer of the highlight.
True, technology has a feature to reduce the area if white, the luminosity of the display increases, and if you draw a white circle on a black background, it increases the brightness to 350 cd / m2. Distribution of brightness to get a good - 90%, contrast - high formally device shown in 1573: 1. However, this is slightly incorrect in this case, since the black color is a black, which turns "off" pixels. Separate commendable angles: they are simply amazing wide, and the image is "extinguished" and the colors move down, but when you look at the display at an angle of 0-5 degrees to the surface. However, it suffers from color reproduction of the display, the problem is partly solved by the fact that it can be corrected by selecting different display modes: Adaptive film AMOLED, photo AMOLED, basic. The first three colors are oversaturated, screaming, with more color variations, but it turns out a broad gamut, covering nearly all standard Adobe RGB. In the transition to native mode rejection are reduced, the colors become more natural, and the color gamut is narrowed almost to sRGB, but it remains a little broader. Display tablet - its zest, with bright, contrasting image, maximum viewing angles, but the bright colors.
Battery
Battery Samsung Galaxy Tab S 10.5 with a capacity of 7900 mAh has shown excellent results in our tests, thanks to its Super AMOLED-display. However, if you enjoy, such as Malevich square on the display, the tablet will run an incredibly long time, as in this case, all the pixels are simply "turned off" and the device virtually puts the battery. If the tablet displays a white color, in this case energy consumption AMOLED-display will be greater than the typical LCD-display. Thus, independent time Samsung Galaxy Tab S 10.5 will depend on what is happening on the screen. With regard to our tests, the tablet lasted an average of 6 hours 28 minutes. three tests under load, 22 hours, 3 minutes. - During peak hours, and 13 hours 21 minutes. - Video playback. The results are impressive, they were higher than the iPad Air, and about the same as at the Lenovo Yoga Tablet his spare battery in a cylindrical pedestal. Samsung Galaxy Tab S 10.5 is fully charged in about four and a half hours, which is very long. Needless charger is compact and does not occupy much space.
Software
Samsung Galaxy Tab S 10.5 runs on Android Kitkat 4.4.2 with a proprietary interface TouchWiz. The tablet is able to work in the mode of multiple windows with customized applications, but even on a 10-inch display applications closely, besides this mode affects the performance. There is also a private mode to hide the personal content separate treatment "Children". The Samsung Galaxy Tab S 10.5 appeared fingerprint scanner. To set the mark, you will have to drag your finger on the key "Home" as much as 8 times, at 5 incorrect attempts you will be asked to wait for 30 seconds and repeat. It is also possible to specify an alternative character and enter the password. I must say that will have to drag your finger in the direction in which you are "recorded" his finger - from the top down. The maximum number of prints that can be registered on the tablet at the same time - three. We decided to conduct a little experiment. As mentioned above, check one fingerprint needed 8 times hold your finger on the button. We asked four people "ask" the mark of the index finger of the left and right hands at once. Thus a tablet could unlock any of these 4 people. However, to our surprise, it was not smart screen function, of which there are only a smart-shutdown. In our view, only it was more or less requested feature - the screen will be turned on until the plate sees that your eyes focused on the screen. On the plate is pre-installed many things besides the standard things, and Google-services: from voice recognition system S Voice, WatchON to control the TV, Remote PC and SideSync to work with the PC and smartphone applications to WebEX conference, Hancom Office Viewer for viewing documents and much more.
Cameras
Samsung Galaxy Tab S 10.5 has two chambers, the same as in the Galaxy Tab Pro 10.1. The front is for video calls, has a resolution of 2.1 megapixels and can shoot Full HD video that is not so necessary, but still impressive. For video resolution is redundant, you need a good, high-speed Internet access. 8.1 megapixel (3264 × 2448) rear camera has a typical set of features - auto focus, LED flash, face detection and smile. With professional cameras can not compare, but with proper lighting, by the standards of the tested tablets, the camera takes very good. The manufacturer has not stinted on a bunch of different settings and effects for an interesting pastime: here and image stabilization, continuous shooting, and set different modes and effects. According to its specifications, the camera Samsung Galaxy Tab S 10.5 surpass camera iPad Air, but we do not recommend to treat the camera as the main criterion when choosing a tablet.
Temperature
In our tests, Samsung Galaxy Tab S 10.5 hardly heats up during operation, apparently due to the cost of the display, also without illumination. Maximum temperature at rest was only 27.1 degrees to the rear. In the state of the load maximum surface temperature of the tablet was 38.6 degrees, almost no discomfort from contact with the body of the tablet. The same iPad Air hotter but not much. The temperature turned suspiciously low, so we repeated the test twice and when charging the tablet from the network, in this case the temperature of the body in some places rose to 44 degrees.
