Sound settings in Sony Xperia Z4 Tablet
Mids and highs are in bulk, so our Sony is even trying to covet and low frequencies... Obviously, physics cannot be fooled, and nothing brutal can be portrayed in such a thin case, but the tablet does not break into wheezing or screeching, and therefore in not too intense drum "notches" it periodically pleasantly surprises.
And this, by the way, without software "uluchshayzers", which more often only spoil everything. S-Force Front Surround, for example, adds a "pan" effect to music. Surround sound (VPT) - for an amateur, can be too clever in many compositions. The dynamic normalizer is engaged in "leveling" the volume of songs, which is also not always good. ClearAudio + really makes the sound clearer, it's a pity that at the cost of "strangling" percussion instruments. No, it's better not to trust the software to improve the sound - in the case of the Z4 Tablet, the original sound is always better.
Iron
And now all gadget enthusiasts are taking a breath to play associations. I say “Qualcomm Snapdragon 810” - you say “device overheating”. However, they joked and that's enough: either Sony worked separately on the internal layout of the Z4 Tablet, or in 10-inch devices the family drawback of the 810 snap does not appear, because we still cannot achieve throttling and a concomitant drop in performance from the Japanese tablet succeeded. For starters - photographs taken with a colorimeter after an hour of cyclic "torture" of the tablet in benchmarks: it is clearly seen that Sony placed the processor in the upper part of the case, where there is no point in holding the tablet with your palms (if you are not an amateur, as in advertising, digging in hard-to-reach places ). Of course, the area near the rear camera becomes very warm, but still not hot, and at the same time it becomes clear why there is no flash in the back - sooner or later the Californian processor could “fry” it from the inside.
Today the Japanese company Sony has officially unveiled its new flagship - Xperia Z4. Some past rumors have told us about the all-metal body of the smartphone. This information turned out to be false.
So what can we expect from updated version the previous flagship -?
First, let's take a look at the phone's geometrical dimensions and weight, versus its predecessor. The body of the Z4 is slightly thinner at 6.9 millimeters. The Xperia Z4 is also lighter than the Xperia Z3 by a whole eight grams, the weight of the new product is 144 grams versus 152 grams for the older model.
These points do not show us any significant improvement. Let's go further ...
Specifications The Sony Xperia Z4 is powered by Qualcomm's updated Snapdragon 810 octa-core 64-bit processor. This chip also has 3GB of RAM. The smartphone is equipped with 32 GB internal memory for data storage. This parameter, if necessary, can be increased with the usual memory card - MicroSD up to 128 GB.
The screen of the Xperia Z4 smartphone is simply identical to the screen of the Xperia Z3. Its size is within 5.2 inches with Full HD resolution. Manufacturing technology - IPS. Such a screen is capable of simultaneously recognizing up to 10 finger touches.
This Triluminos screen is protected by heavy-duty glass and supports the X-Reality Engine technology.
The back of the case contains the same 20.7 megapixel matrix for photo and video shooting. All camera options and capabilities are similar to those of the Z3 smartphone. Truth, front-camera slightly better and received a 5.1 megapixel matrix instead of 2.2 megapixels.
The pre-installed operating system of the new device is. The Xperia Z3 shipped with more than old version firmware and only recently Sony announced the update of the gadget to.
So what's new in the Sony Xperia Z4 smartphone?
And the answer to this question will be very simple - nothing special or very little new! The technical characteristics of the new item are not significantly better than its predecessor. Sony has a habit of releasing a brand new flagship twice a year. Perhaps this model is presented just for "show" or the company felt the need to introduce a new device for the Asian market. Who knows!

Type of
Determining the type of device (phone or smartphone?) Is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to opt for a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly shorter than that of a simple phone.

Hello everyone! I had a short break in anticipation of an unusual novelty. And now it fell into my hands latest tablet from SONY under the name "Xperia Z4 Tablet". As you might guess, this is the fourth revision. this tablet... With each new model, the tablet becomes cooler and cooler, in fact, I'm wondering when the limit of this very coolness will come. Apparently in the SONY company they think that this is still very far away and I probably agree with that. Xperia Z4 Tablet - represents the quintessence of its kind in this direction and sometimes it's hard to believe that the company was able to create such an advanced and unique model. However, all the details are further in the text.
I'll start this review with the technical characteristics:

PACKAGE
The tablet comes in, let's say, a small cardboard box. The cardboard is quite dense, the color is white with a matte shade. The packaging is quite high quality and will last a long time.
On the front side there is an image of a tablet in black and white. In the right upper corner the product's name.
The right and left ends of the packaging are painted black.
On the back of the package you can see the available colors, as well as read a short technical information... The tablet is made in China.
Inside the box, the tablet is packed in a shipping bag, on the screen there is a temporary film for transportation.
EQUIPMENT
Now let's take a look at what can be found in the bowels of the box.
1. The tablet itself.
2. Charger.
3. Micro USB to USB cable.
4. Quick start guide.
5. Documentation of the technical plan.
As you can see, the delivery set is the minimum possible, there are only the most necessary components for work.
APPEARANCE
For review, I got a version in black, but there will be other colors on sale.
I'll tell you right away that on this moment The Xperia Z4 Tablet is the thinnest, lightest, most powerful rugged tablet ever. So far, no one has even come close to a product from SONY in terms of these parameters, but in fact, hardly anyone will do it. By the way, since the time of the previous tablet, no one has released a similar product.
When you take a tablet in your hands, you can't believe that it is so light and thin. The weight is only 392 grams and is very light for a tablet like this. The thickness is also striking, at just 6.1 mm. In general, when you hold a tablet in your hands, you do not leave the feeling that it can simply simply crumble in your hands, but of course, in fact, it is not.
In appearance, the tablet does not differ much from the previous models, the company strictly follows in this direction. Frankly speaking, I personally have become boring with "Omni Balance Design" and in fact I see everything the same for the fourth time, I already want some differences or some kind of zest.
And so, the tablet has very slightly rounded corners in which metal inserts are mounted, which in turn protect the corners of the tablet if you drop it.
A metal edging runs along the perimeter of the tablet, and only the slot for the SIM card and memory card is covered with a plastic flap. All other controls are also made of metal. The power button is made of silver metal and stands out well against the general dark background tablet.
The screen frames in this version have become a little narrower, but there is still a fairly large margin in width. In the future, it will probably be possible to put a screen with a larger diagonal in such a case. The entire front surface of the tablet is covered with a glass panel.
The back of the tablet is already made of dark plastic. Moreover, the texture of the plastic itself is matte and rough. Plus, in such a coating, it is almost complete absence of scratches, as well as fingerprints do not remain on such a coating, and the chance of dropping the gadget from your hands is also minimal.
In general, holding the tablet in your hands is very convenient and comfortable, it is quite possible to use your hand, the weight allows. There are no protruding elements in the design of the tablet, everything is smooth and smooth.
By tradition, all tablets from SONY are protected from external factors, and the hero of our review was no exception. The protection level in this tablet is IP68 and this maximum value for mobile technology. The IP68 parameter tells us that this tablet is completely protected from the penetration of dust of any diameter and in any quantity. Also, this tablet is completely protected from moisture. It is possible with it to completely submerge the input to a depth of 1.5 meters and within 30 minutes.
I would like to note that the 3.5 mm jack remained open and you can safely fill it with water, however, this was also in the previous model. But in this tablet, the Micro USB connector was also opened, and it remains a mystery to me how the company made it resistant to moisture.
I can't say anything bad about the build quality. SONY is SONY. Of course, I am not an ardent fan of this brand, but in this case I can confidently declare that the build and overall quality of the product is just perfect.
CONTROL ELEMENTS
Traditional overview of controls.
At the top there is a 3.5 mm headphone jack. A slot for a memory card and a SIM card. There was also a place for a microphone.
On the right side there is only a Micro USB connector.
In turn, there are no controls on the bottom end.
On the left side there is a power button and a coupled volume control button.
On the back there is only the main camera, NFC sensor and the manufacturer's logos.
On the front side: front camera, automatic brightness control sensor, "SONY" logo, status indicator. The touch buttons occupy the highlighted area on the screen.
SCREEN
I am not a supporter of screens with over high resolution in smartphones, but in tablets this resolution is different.
And so with us IPS matrix with a diagonal of 10.1 inches at a resolution of 2560x1600 pixels. The pixel density at these values is 299ppi and I personally did not notice any individual pixels on the screen.
10-touch multi-touch.
The IPS matrix provides maximum viewing angles, which is actually demonstrated by our tablet.
In the sun, the screen also showed itself with positive side, the image fades slightly and the information is always visible, the anti-glare filter in action.
The screen is made using OGS technology, which eliminates an air gap between the glass and the touch layer. I would like to note the effective oleophobic coating, prints practically do not remain on the screen, and those that do exist are easily removed. As mentioned above, the screen is closed protective glass, but the type of this glass SONY company traditionally does not disclose.
In the settings of the screen there is such a parameter as "X-Reality for mobile" when activated, the quality of photos and videos during viewing is improved.
There is also "Extreme brightness mode" when you turn it on, the maximum color quality is increased at once.
The maximum brightness level can be described as high, there is even a margin, and this is good considering that previous models could not boast of this parameter. For example, compared to the Xperia Z2 Tablet, the maximum brightness has increased by 40%.
The adaptive dimming function changes the brightness of the screen based on the ambient light analysis.
For lovers of fine-tuning, there is such an item as "White balance" where you can actually manually adjust this value.
I really like the smart screen backlight feature. When you hold the screen in your hands, it is always on, but when you put the tablet on the table, the screen turns off. This function works on gyroscope readings.
From this graph, it can be judged that, in general, the gamma curves are quite stable. We can talk about the correct saturation of color shades.
But with the color gamut, things seem to go wrong. It's a long way to the sRGB standard, the green color is especially strong. This parameter allows us to say that color rendition suffers a little.
The gray wedge points also lie far beyond the Delta circle.
The color temperature is quite far from the 6500k standard. Cool tones can be present in the palette.
Color channels are also unstable. There may be color problems.
If you do not take the readings of the measuring device in the analysis of the screen, then this screen is still pretty good. An ordinary consumer is unlikely to notice any flaws in the screen setting by eye.
CAMERA
The main camera is an 8.1 megapixel sensor with Exmor RS technology. The matrix uses as many as 6 lenses and again it is not clear how the company managed to cram all this wealth into a 6.1 mm case, miracles and nothing more.
It is generally accepted that cameras in tablets are far from their counterparts in smartphones in terms of shooting quality, of course there is some truth in this. But the camera in the Xperia Z4 Tablet shoots pretty well. Personally, I have noticed slight white balance issues that are otherwise obvious and visible problems no.
There is autofocus, and it works very quickly, and the camera itself is notable for its rate of fire.
The main mode of operation of the camera is "Super-auto". The camera itself analyzes the external situation and selects desired parameters... You can use manual settings, but personally, I did not notice any difference in work and in the pictures, so the "Super-auto mode" confidently copes with its tasks. It is worth noting the excellent macro photography, therefore, there will be no problems when photographing the text.
The main modes of operation of the camera are as follows:
MANUALLY. Manual setting parameters of shooting a photo and video camera.
AR EFFECT. You can take photos and videos with virtual scenes and characters (augmented reality).
ARTISTIC EFFECT. Effects for photos and videos.
PANORAMIC OVERVIEW. A mode for taking a panoramic shot.
The actual camera settings can be viewed in the screenshots provided:
Next, I propose to independently evaluate the quality of the shooting. I want to warn you that it is constantly cloudy and raining in Vladivostok, so it is almost impossible to take photos in sunny weather. Below, as always, there will be a link to the originals of photographs.
The maximum video quality is FullHD at 30 frames per second. Further several videos in various
permissions.
The front camera in the Xperia Z4 Tablet is wide-angle and is equipped with a 5.1-megapixel sensor with a 25mm lens, thanks to which the quality of video chat is always at its best.
A couple of shots for quality assessment:
The front camera can also shoot FullHD video at the same 30 frames per second.
SOFTWARE AND TABLET SETTINGS
In this section, I want to step back from my style and demonstrate the interface and operation of the tablet using this video as an example.
IN WORK
Xperia Z4 Tablet is the first tablet in the Russian market where Qualcomm Snapdragon 810 is installed. We have as many as 8 cores at our disposal, but they work separately. Four powerful 64-bit ARM Cortex-A57 cores are complemented by four energy efficient Cortex-A53 cores.
Responsible for the graphics Adreno 430 with support for 4K-resolutions, OpenGL ES 3.1, hardware tessellation, geometry shaders, programmable mixing and new security features; Compared to the Adreno 420, the new GPU delivers up to 30% faster graphics performance.
Actually, what else does an inveterate gamer need? If you look at the results of synthetic tests, you can see that the Qualcomm Snapdragon 810 "tears" everything. Even a 2k resolution screen does not become an obstacle for such a powerful bundle. Needless to say, when the tablet is working, there are no lags and even more so brakes, everything is very smooth and clear. The sensor responds instantly without any delay.
Now let's turn to gaming applications. I want to say right away that at the moment no game application where are the opportunities this processor will be 100% involved. Further, just a cut of a game video and, as they say, no comment.
The tablet has as many as 3GB of RAM, this is certainly not a record, there are smartphones with 4GB of RAM on board. The system takes about 500MB for cache, 1GB is used simultaneously on average, and about 1.3GB remains in free use.
Permanent memory in the tablet 32GB. We still have about 20GB in free access. It should be borne in mind that versions with 16GB will not be on sale and this is good.
The 128GB card worked in the tablet without any problems. You cannot transfer applications to an external memory card and, in fact, it only serves to store various media content. So the remaining 20GB should be used rationally, but in any case, a dozen cool games can be installed.
I really liked the sound in this tablet. Two loud stereo speakers deliver real quality sound. The volume is just excellent and even with a margin. At maximum volume, there is no background or sound distortion. Low frequencies are perfectly heard and it's just great.
This tablet is compatible with Hi-Res Audio technology. This sleeve is already built into the Z4 Tablet. If you have Hi-Res Audio compatible headphones, you simply take advantage of this technology by using these headphones.
High-definition audio provides higher audio sampling rates. High definition audio frequency - 24 bit / 96 kHz and 24 bit / 192 kHz. High definition audio files (DSD, DSD-dsf, WAV, AIFF, FLAC, ALAC) are encoded in one of six popular formats.
Of course, the tablet has a full-fledged GPS module, as well as support Russian system GLONASS. The first cold start took me only about 30 seconds. Further, on average, the satellites were displayed according to the 9/15 scheme. The positioning accuracy on the ground was about 3 meters.
You can install a "nano" SIM-card in the tablet and thereby turn your tablet into a full-fledged smartphone with a giant screen and top-end filling. Since we have Qualcomm Snapdragon 810 at our disposal, we get LTE Advanced 4th generation, which provides data transfer rates of up to 300 Mbps and provides the widest support for LTE spectra to date (the company claims that these are the first 64-bit processors on the market with integrated support for LTE Advanced worldwide). Simply put, we are provided with high-speed Internet all over the world.
Well, in conclusion, I will say that the function of connecting external devices is fully implemented. In the presence of USB-OTG cable you can connect almost anything where there is a full-fledged USB connector.
OFFLINE OPERATION
The battery in our case has a capacity of 6000 mAh, is it a lot or a little, let's find out further:
1. Work in 3D applications - 5 hours.
2. Video playback at 50% screen brightness, 720p video - 8 hours.
3. Working in "just a phone" mode with a BT headset connected - 3 days.
4. MP3 playback in headphones - 74 hours.
5. Mixed cycle: video, games, communication, music - 18 hours.
Considering the thickness and filling of the tablet, I state that autonomous work was a success. Qualcomm quick charge 2.0 technology is supported, in an hour you can charge the tablet up to 70 percent, in 2 hours 30 minutes the tablet is fully charged.
ENDURANCE TESTS
In this test, I tried to scratch the screen with improvised means, but as you can see, nothing came of it.
And here rear panel it can get scratched if you do not use the protective case.
A trivial test, but nevertheless the tablet perfectly tolerates water procedures.
The fall of the screen down from a height of 1 m.20 cm did not adversely affect the tablet itself.
Falling to an angle also did not affect the operation of the device.
A shot at the screen from 10 meters from a pneumatic pistol did not cause any damage. The screen remained intact, the tablet worked
Shot from 3 meters in back proved fatal. The lead bullet almost flew out. After this shot, the tablet did not work anymore.
ATTENTION. Ladies and gentlemen, if you are going to carry out such tests, then do not forget to take out, for example, memory cards from the tested devices. Here is a good example of how easy it was to ditch a 128GB memory card.
CONCLUSIONS
While the tablet rushes to store shelves, let's turn to the official price of the online store SONY. We see that the price for this product is 46,990 rubles, as my friend said, this is protection from rogue. Well, as they say, hit the sky with a finger. With such a price in our country, and even with increased prices, I think sales will be quite small. Today this tablet has no direct competitors, SONY understands this and actually uses it. Want the best - pay money!
PROS:
1. High quality workmanship.
2. Protection according to the IP68 standard.
3. The thinnest, the lightest.
4. Supports LTE Advanced.
6. Great stereo sound.
7. Good camera.
8. Work in cell phone mode.
9. Good time autonomous work.
MINUSES:
1. "nano" SIM card.
2. No IR transmitter.
3. There is no way to transfer applications to a memory card.
4. High price.
That's all. Buy only the best! Thanks to everyone who took the time to read this review. This is my last review in June. I'm going on vacation for a month ...
Good luck to everyone and see you soon!
So Sony decided to release a new flagship, although it was announced only for Japan, but not without reason. The new model won't be much different from the Sony Xperia Z3. Explaining the reason for the repetition is quite simple. good design and not bad functionality did their job and the smartphone turned out to be quite successful, and the emergence of a new model is explained by the continuity of production, so it is not economically profitable to fence a garden for the sake of an existing device, only with minor changes. Today I want to pay attention to this particular smartphone, since the interest in it is quite high, especially for those who are interested in new products, as well as, of course, Sony lovers. In this article, we will look at the alleged main characteristics, as well as see its possible pros and cons, which will help you choose best smartphone for a gift to loved ones or buy yourself.
First impression
One of the major changes is the reduction in thickness. The new flagship will be thinner than HTC, Samsung Galaxy S6, IPhone 6. The thickness of the Sony Xperia Z4 is supposed to be about 6.9 or 6.3 mm. This device will have a slot for applying a card. Rumored to be new phone will also be protected from dust and moisture. Note that the owners of previous models complained about poor build quality, although the gadget was presented as protected. In addition, the microUSB connector was moved to the bottom end, and it still does not have a plug, but if the assembly is of high quality, then immersion in water will not bring much trouble. In the end, I can say that appearance will not change, so you can just read the description of the Sony Xperia Z3.
Display
It is said that there will be two variants of the screen with FullHD and QuadHD screen resolution. 5.2-inch diagonal, 1920-by-1080-pixel resolution. The display will be protected from scratches and other damage by Gorilla Glass. The protective glass has earned the approval of both owners and manufacturers. In the past, the company also had a problem with the firmware, we are talking about the so-called dead pixels, which eventually make themselves felt. In other matters, this can be fought, so that everything is not so scary. It is not known about the rest of the characteristics, but according to the experience of previous models, the color rendition is good, the viewing angles are maximum, the screen behaves well in the sun. V general characteristics pretty good, we can only hope for high-quality firmware.
64-bit Qualcomm Snapdragon 810 processor. Random access memory 3 GB, built-in 32 GB, expandable up to 128 GB using a memory card. The Sony Xperia Z4 will run on Android 5.0 Lollipop, with the addition of Sony's shell software interface. In principle, normal characteristics, programs and applications pull normally without freezes, there should be no problems with toys.
The battery capacity is 2930 mAh, which is definitely not a bad indicator even for such a processor, besides, it should be borne in mind that the display is not very large, which will allow the phone to hold a charge for a full day. According to the previous model, I can say that the smartphone holds a charge: talk time 16 hours, standby time 920, listening to music up to 130, and watching videos up to 10 hours. In general, I can say that the smartphone does not have a bad battery, but, of course, it depends on who uses it.
Camera
The main camera is 20.7 megapixels, the front camera is 5.1, which will help to take a high-quality selfie, not to mention communication via Skype. It is also rumored that there will be the possibility of optical image stabilization, which will definitely improve the quality of the photo. Also, apparently, the autofogkus function will remain. Of course, there are smartphones with more the best camera, but here, too, everything is not bad, at least in the daytime the pictures are good.
