We can say - Everything. Smart, there are no glitches yet, very energy-intensive, easily enough for the whole day, although I rarely set the brightness of the screen to maximum, but it's too early. The Internet is fast. The sound is very good in headphones, at least someone will not seem loud It's enough for me. True, the headphones are not earplugs, but full-sized senheiser. I have not tried small ones. Games go easily, while there is no big heating, What else distinguished from my previous phones is the sound when making calls, the interlocutor is always heard perfectly, no extraneous sounds and distortion of the voice, at first it was even unusual. Even if it was noisy around and you could hear me perfectly. The camera is quite good, and the photo always turns out to be quite clear even during the day or at night. The flash is bright.

A very nice sensor, like all Sony, however; + good sound, very good for a smart, voluminous, not very loud, but clean. In some headphones, there will be no bass (if the headphones themselves do not focus on low ones, the bass will be very weak); + speed of work, 4 cores (although a media library), 1 GB of RAM - quite enough to work without brakes for calls, music, Internet and some other applications (I don't play games); + you can turn off almost all applications (which I did), battery life will significantly increase, Stamina mode (it helps, you can add exceptions); + appearance, nice matte back panel; + build quality; + non-removable battery; + support for Micro SD up to 32 GB;

1. 5MP camera ... Even my previous Sony Xperia tipo with 3.2 camera, in my opinion, took better pictures. Although, during the day, with different camera settings, the photos come out quite well! The front-end has not yet been used.
2. Speaker. When talking, some complain that they do not hear me well. Yes, and I myself noticed that the sound seems to be removed, but for me this is not very critical.
3. As soon as Wi-Fi catches, it immediately starts updating all programs.

The short usb cord included in the kit is only 10 cm, it gets very hot when you play games, there is little memory, out of 8 GB only 4 with kopecks are available, it is impossible to transfer some programs to a USB flash drive and delete unnecessary ones

1. Camera. On my previous phone, Nokia Lumia 610, the 5 megapixel camera shot better than the current one at 8. Even the front camera seems to me better than the main one.
2. About 4 GB of built-in memory is available. Some applications cannot be transferred to a memory card.
3. No headphones included and very short USB.
4. So far, only one case for this model.

The sound is quiet, especially if it is lying on something. The unlock button protrudes strongly from the case, you can accidentally press it if it is somewhere far away, in a bag, for example. Well, I didn’t notice the essential ones.

I'm not sure about ips, the screen is strongly illuminated, it is difficult to see in the sun, dull by itself (although on the other hand it does not consume a charge), the colors are slightly distorted when viewed from corners;
- 4GB on board, not 8!
- the screen is not capacitive, it is easily controlled by some stylus, wires from headphones and a pocket of jeans (my jeans are very fond of changing songs);
- there are a lot of unnecessary applications in smart;
- the keyboard is bad: it changes dictionaries by itself and moves the cursor to the end of a word suddenly when editing a word with all corrections disabled. It is very inconvenient to type;
- the unlock button is on the side in the middle, personally I am not comfortable with this arrangement.

The camera is supposedly 5 megapixels, in fact, it's just horror, some stains and unnatural colors. Wifi works only when you turn on 3G, (you can turn off 3G only through data transfer, then Wifi is cut off - as intended), more precisely, and then it does not work - when all the gadgets are attached to Wi-fi, the valiant Xperia writes "Wifi rejected from - for an unstable signal ". The system itself is clumsy to the point of disgrace. It seems to be Android and that's it - but there are frightening differences from the usual android, which, as if out of spite, were created by deranged people. For example, to make a call, you need to press the handset icon, enter contacts (the button at the top of the screen), then the search icon - it is at the very bottom of the screen. The search line itself immediately appears at the very top of the screen. To dial a couple of letters of the desired subscriber, you immediately need to use your finger again

1) Meager equipment (except for the charger there is nothing)
2) Short charger cord (causes a lot of inconvenience)
3) The general appearance is satisfactory, but has gone away from the SONY style, and has become at the level of some Chinese noname phones, only a beautiful power button and SONY icons save from oblivion
4) An extremely mediocre camera that clearly does not live up to expectations. Previously, SONY put good cameras even in budget phones, but now there is no such thing (although the official website claims that the camera is wonderful)
5) Outdated hardware (old processor and graphics)
6) The IPS display is poorly configured, the colors are unsaturated and incorrect, graininess is noticeable due to the small number of pixels per inch (in the settings you can adjust the white balance

There is a gap in the lid on the left side, sometimes it loses its connection via Wi-Fi and there are problems with entering the Gmail mail when authorizing the phone in the playmarker (it always gives an error). After rebooting n times, the problems with Gmail disappear. Complete USB cable 8 centimeters long.

Sony Xperia E4 is a smartphone with a good battery, sufficient performance for basic tasks, good design and a moderate price tag. Of course, any device has its own nuances and, as a rule, there are even more of them in a budget device, so the E4 is no exception. Without wasting a minute, we go to review.

Equipment

The packaging familiar from other Xperia products (thick cardboard with good printing) hides the phone itself, a charger, a Micro USB cable and that's about it. Sony has not been seen in the generosity of various bonuses for buyers before, so immediately to the appearance and ease of use.

Design

The appearance of the smartphone is simple, uncomplicated and at the same time interesting. The smartphone is wide enough, even unusually wide when compared to devices from competing companies. Nevertheless, it fits well in my palm, wide enough. Owners of narrow palms thinking about buying should definitely try the device live. Impressions may be very different from mine.

Since we're talking about the convenience and dimensions of the phone, it's worth taking a look at the size plate.

	Length	Width	Thickness	The weight
Sony Xperia E4		74,6	10,5
Lg leon	129,9	64,9	10,9
Huawei Honor 4C	143,3	71,9
Samsung Galaxy Grand Prime	144,8	72,1

The back cover is made of plastic and covers all sides of the smartphone. On the right side are the volume keys and the power button, made in the corporate style of Omni Balance.

The buttons on the lid are just repeaters of the keys, which are located directly on the body, under the back panel. It is clear that it is not easy to press on them without the battery compartment cover installed, and in general it is not necessary.

Surprisingly, the Japanese have not installed a separate physical key to release the camera shutter. The presence of the latter has always been typical even for devices that could not boast of photo quality, but now the policy has apparently changed course. Where to? It's not clear yet. Instead, any of the volume keys are responsible for taking pictures. And what, in principle, is an option.

There are no elements on the bottom except for the hole for attaching a lanyard to the device. By the way, Sony is perhaps one of the few manufacturers that still continues to equip their products with lace loops. Maybe the president of the company wears his phone this way?

On the upper part, right in the lid, there is a hole for connecting headphones - standard 3.5 mm jack. There is nothing else here.

The Micro USB connector is located in a non-standard place - on the left side of the device. Whether it is convenient or not - let everyone decide for himself. But a little strange - that's for sure.

At the back is the main camera lens, and next to it is an LED flash. In the middle - the company name, and closer to the bottom of the slot for the multimedia speaker.

The volume of the latter is average, on a noisy street, especially if the smartphone is in a bag, it costs nothing to miss an incoming call.

The back cover is removed interestingly. Anywhere along the perimeter of the sidewalls, it is enough to pick it up with your fingernail and the lid will give in. Contrary to expectations, the battery is not removable here - it is hidden deep in the case and you cannot replace it yourself without losing the warranty.

There are also slots for installing a SIM card (Micro) and a memory card. One of the recesses is tightly sealed. This means that in nature it is found and even sold here, a two-symbol version of the phone - Sony Xperia E4 Dual. Later we will definitely talk about the modifications existing on the market, since there are enough of them in stock.

Above the display is a standard set of elements: a front camera, earpiece, proximity sensor and ambient light sensor. The brightness control is generally correct.

The hole for the earpiece is located symmetrically to the same slot, which is already under the screen. A spoken microphone is hidden here.

The manufacturer successfully played with this moment and did not make additional holes around the perimeter of the case. The touch-sensitive system control keys are part of the software interface, so it is convenient to hold the smartphone in landscape orientation when playing games or watching videos - there are no accidental presses.

The display itself is covered with a protective glass. There may be an oleophobic coating, but it does not fight the accumulation of fingerprints in the best way. When the screen of the device is in the bright sun, greasy fingerprints make it difficult to see the details of the interface - you have to hide the device in the shade.

There is a small edging around the display bezel that protrudes slightly above the body. It is plastic and quite sharp to the touch, but fortunately it does not cause any inconvenience.

Two color variations will be available on our market: black and white. Of course, you won't go too far, but there are the most popular colors - classics in one word.

Display

The manufacturer installed a 5-inch screen in the smartphone with a resolution of 960 x 540. The density of dots per square inch does not exceed 220 ppi. This, of course, is not much, so individual pixels are quite easy to distinguish. You don't need to have special eyesight for this.

The viewing angles are good. The image is not inverted, does not fade and remains fully readable at any angle of inclination. It is clear that the brightness drops, but this is typical for all LCD screens.

Specifications Sony Xperia E4 (E2105):

• 1.3 GHz MediaTek MT6582 processor (4 cores)
• video chip Mali-400 MP2
• RAM 1 GB
• 8 GB built-in storage (4.78 GB actually available)
• Support for Micro SD memory cards (up to 32 GB)
• 5 '' display (TFT) 960 x 540 pixels, Multitouch (up to 4 simultaneous touches)
• front-camera
• main camera 5 megapixels
• sensors: accelerometer, light and proximity sensor
• battery 2300 mAh
• connectors: 3.5 mm, Micro USB (2.0)
• Android OS 4.4.4

Wireless interfaces:

• GSM GPRS / EDGE 850, 900, 1800, 1900 MHz, UMTS HSPA + 900, 2100
• Wi-Fi (b / g / n /), Bluetooth 4.1

The system on a chip (SoC) MediaTek MT6582 is used here as "brains". It is based on a relatively old (late 2013) processor with four Cortex-A7 cores. The chip is produced on the basis of a 28-nm technical process and includes a Mali-400 MP2 video accelerator with an operating frequency of up to 500 MHz.

UMTS / HSPA + (3G) modules, Wi-Fi, Bluetooth and GPS wireless interfaces are built directly into the SoC. This explains the lack of 4G support - this requires a different processor, which is installed in the more advanced version of the Xperia E4g.

Our hero does not shine with performance. You can play modern toys only by setting low graphics settings. Some games may not launch at all.

Quite serious brakes are observed even in the AR Effect camera mode. Virtual gnomes jump onto the screen with a long delay, and during the shooting they move with visible delays. You can hardly call it comfortable using this feature on a smartphone.

There were no obvious and serious brakes in the interface of the system. Yes, the device is thoughtful and does not instantly open any installed applications, but the proprietary shell is generally well optimized. It is comfortable to work with it when performing ordinary, non-resource-intensive tasks.

At the end of the section, of course, the results of passing synthetic tests are in their rightful place.

Camera

Front camera 2 megapixels with a maximum resolution of images up to 1600 x 1200 pixels. There is no need to talk about any special mode for selfie-maniacs. For video calls, the front module will do quite well, but for your own portraits it is much worse.

The main photo module is represented by a 5-megapixel sensor, which is capable of taking photos at a resolution of 2560 x 1200 pixels.

The shooting quality can be called satisfactory. It often happens that the sensor misses the exposure or focus, as a result of which the frames are either blurred at the edges or overexposed in some places.

You can only deal with this by taking 3-4 pictures at a time. This can partially save the situation.

In general, what to say. Everything can be seen in detail on the example of photos shot with the Sony Xperia E4 camera.

Of course, like all other devices of the company, there are a whole bunch of different interesting shooting modes here. You already got to know a little about AR Effect when describing the performance of the device and using the examples of pictures above. The most interesting scenario is Timeshift Burst. Using an example and we described this technology in detail, and in the case of E4, it can only work as a cool feature. Nevertheless, the initial level of photographic materials does not reach the necessary level.

The smartphone can record video in a resolution of 1920 x 1080 pixels with a frequency of 30 frames / sec. Except for the problems described above, the quality of the videos is not bad.

Battery life

The manufacturer claims over 10 hours of talk time on 2G or 3G networks, continuous music playback for 48 hours, and video playback for up to 7 hours. All this is possible thanks to the 2300 mAh non-removable battery.

In practice, battery life is the strongest point of the device.

The E4 can operate under load for a full two days. In moderate use, this figure can be improved up to 3-4 days of operation without connecting to a charger.

And if you take into account the preset power saving modes, then even four days is not a record.

Models and prices

Our review is about the Sony Xperia E4, also known as the E2105. More advanced is the Sony Xperia E4 or E2003. The modification differs for the better due to the MediaTek MT6732 processor with a frequency of 1.5 GHz versus 1.3 GHz in the regular version, the Mali-760 MP2 video accelerator, as well as support for LTE frequencies (bands 1, 2, 3, 4, 5, 7 , 8, 28). Of course, the cost of the last device is higher (from 10,490 rubles).

Modification E4 Dual or E2115 does not differ in anything except the presence of a second SIM card (only 2G on the second slot). The same processor, the same video chip, and so on. The price is slightly higher and amounts to 9,990 rubles.

Hopefully now you have a complete picture in your head of what Sony offers to consumers in the budget range.

Outcome

Model on the market now Sony Xperia E4 can buy for 8,990 rubles and this price can be considered quite adequate. In return, you get an ordinary, modern budget device that can perform almost any (see not resource-intensive) tasks and lives on one battery charge for a day with a little more than products from other manufacturers.

Yes, a display with a higher resolution could be installed here, the camera is better, as well as equip the device with support for LTE networks, but following the realities of the market, this would already be something from the category of 12-13 thousand rubles.

Nevertheless, Sony, apart from the cool and, so to speak, chubby design of the E4, did not offer anything interesting that would make the smartphone stand out from its competitors. Yes, the device is reliable, working, the price is adequate and that's it.

The smartphone has one single competitor that beats it on all fronts (with the exception of battery life) - Huawei Honor 4C. The latter stands out against the background of competitors due to its very good characteristics and a very affordable price. However, it was not without a fly in the ointment - the Chinese just won't be able to buy this. Read more in.

An updated version of the cheapest Sony smartphone

The most inexpensive, budget line of Sony smartphones, consisting of simple mobile devices of the Xperia E series, has been replenished with several models at once under the general name Xperia E4. This small subfamily includes both modifications with support for one or two SIM-cards, and models that support work in 4G networks. Models with 4G support differ not only in the additional network module, but also have noticeable external differences: design and body materials. We will return to such a modification, but for now we have in our hands a model without LTE support, but able to work with two SIM-cards. This modification has an E2115 index according to the internal classification, and it was she who became the heroine of today's review.

Equipment

The Sony Xperia E4 Dual smartphone comes on sale in a slightly different shape, flatter, but also slightly larger, atypical for the line of budget Xperia E devices, a box made of thin unvarnished cardboard with one small inner pocket made of the same cardboard. The packaging, like its contents, does not claim to be premium, everything is simpler here. However, even the most expensive products of the Japanese company do not have a chic look.

The set of accessories consists of a compact charger (5 V, 850 mA), a short 10 cm Micro-USB connection cable, which is familiar to the E series, and a stack of paper documents. The headset was not included in the kit, and there were no other additional accessories in the box.

Appearance and usability

It is curious that, unlike the expensive flagship models, in its budget line, Sony does not at all maintain continuity in design. The next novelty from the Xperia E series at number 4 has no similarities at all with its predecessor, the Xperia E3. And it should be noted that this did not go to her benefit: for something, but the design of its Xperia E3 could definitely be proud of. The appearance of the smartphone was liked by everyone who took this cute, austere and even somewhat solid, thanks to the preserved features of the Omni corporate design and protective polycarbonate inserts embedded in the corners, albeit an inexpensive device. In contrast, the Xperia E4 has completely lost all its originality and complexity, turning into an ordinary inconspicuous "remnant", assembled from two halves with strongly rounded edges. No straight edges, sharp corners, and even more so polycarbonate inserts - there is absolutely nothing to catch the eye, and such a device is now indistinguishable in appearance from the many nameless Chinese handicrafts.

The small-sized body of the Sony Xperia E4 Dual has a rather simple device: most of it is made up of a whole plastic casing, which is put on the frame and forms not only the back cover, but also the sidewalls - a sort of trough made of cheap matte plastic. The mass of the smartphone is small, due to its small dimensions, you can comfortably hold the device in your hand. Its surfaces cannot be called easily soiled, although the matte plastic is hard and even a little slippery here - the slightly rubberized soft-touch effect would definitely not prevent it. By the way, such is the case in the Xperia E4g modification, and this pleasantly distinguishes the model with LTE support from the usual modification that we have been testing.

The outer cover has no special hooks; to remove it, you just need to pull it off anywhere from the glass, and then remove it entirely. At first it seems inconvenient, but you get used to it quickly, you can get the hang of it, although the mounting method is not the most sophisticated.

All mechanical buttons are attached to a removable cover, so when the cover is removed, it becomes impossible to use the smartphone. The keys don't always work perfectly, but overall there are no particular complaints about the mechanical controls.

Inside, under the cover, all three card slots are located in a row: two for SIM cards and one for a microSD memory card. SIM card slots are equivalent in their capabilities, both support Micro-SIM cards. Slots for SIM-cards do not have spring-loaded gripping mechanisms, cards are held only due to frictional force and are sometimes quite difficult to remove, especially if an adapter is used.

The front of the case is completely covered with protective glass with a very poor oleophobic coating or even without it at all - the glass is instantly covered with fingerprints and is very hard to wipe off. There are two symmetrical slots at the top and bottom of the glass - for the speaker and for the microphone. In the upper part above the screen, in addition to the eye of the front camera and sensors, there is also such a useful element as an LED notification indicator - a dot glowing in different colors notifies about the charging status and incoming events.

Unlike the older models, there are no two speakers here - the bottom slot with the grill serves only to accommodate the microphone. There are no buttons under the screen either, the system and applications are controlled using virtual on-screen buttons, so the empty space at the bottom under the screen looks a bit redundant.

Accordingly, the main speaker is brought out to the back side in the slot in the cover. There are no protrusions near the hole, so the sound is significantly muffled when the smartphone is placed on a hard surface with the screen facing up.

At the top of the back wall is the main camera module next to a single-section LED flash that can work as a flashlight using a pre-installed program.

The universal Micro-USB connector located on the left side edge, to our surprise, and unlike the Xperia E3, does not support connecting additional devices and flash drives in OTG mode. The connectors are not covered with covers, since the device is not protected from water and dust. There is no support for wireless charging either. But the strap mount in this modification was returned (in the Xperia E3 it had to be removed due to the polycarbonate corners).

As for the color scheme of the new smartphones, in this regard, Sony continues to unpleasantly surprise: unlike the bright lemon and copper shades available to choose from among the modifications of the Xperia E3, everything here was limited to a dull list of two standard black and white options. In general, we can say with confidence that in terms of appearance and design, the new product called Sony Xperia E4 Dual is much inferior to the previous model Xperia E3, and this is sad.

Screen

The Sony Xperia E4 Dual smartphone is equipped with a touchscreen IPS-matrix with a small diagonal by modern standards, especially given the considerable physical size with a five-inch diagonal. The screen dimensions are 62 × 110 mm, the diagonal is 5 inches, but the resolution is only 960 × 540 pixels. Accordingly, the pixel density is low here: it is only 220 dpi.

The bezel around the screen is wide enough (at least 6 mm from the sides), the width of the bezel is 12 mm at the top and 15 mm at the bottom.

To adjust the brightness level, you can use automatic adjustment based on the operation of the ambient light sensor (in the first models of the series, it was not even available). The multitouch technology here allows you to process 5 simultaneous touches. The smartphone also has a proximity sensor that locks the screen when the smartphone is brought to the ear. Activation of the screen by double tapping on the glass, control with gloves or wet fingers - none of this budget Sony model from the developers got.

A detailed examination using measuring devices was carried out by the editor of the "Monitors" and "Projectors and TV" sections Alexey Kudryavtsev... Here is his expert opinion on the screen of the test sample.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are much worse than that of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). The surface of the matrix itself under the glass is matte, so the screen reflects both direct light sources (external surface) and scattered light (matrix surface), this reduces readability in conditions of strong external light. For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left - Nexus 7, on the right - Sony Xperia E4 Dual, then they can be distinguished by their size):

The Sony Xperia E4 Dual's screen is noticeably lighter. On occasion, I would like to ask the creators of this device what they were guided by when ordering matrices with glued matte film. Both the sticker stage and the film itself cost some money, and the result is a significant decrease in consumer qualities. The doubling of reflected objects in the Sony Xperia E4 Dual screen is very weak, this indicates that there is no air gap between the layers of the screen (more specifically, between the outer glass and the surface of the LCD matrix) (OGS type screen - One Glass Solution). Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in case of cracked outer glass is much more expensive, since the entire screen has to be changed. True, in this case, the possible improvement of antiglare properties is completely leveled out, only the low maintainability of the screen remains. There is no special oleophobic (grease-repellent) coating on the outer surface of the screen, so fingerprints can be removed with difficulty, but appear instantly.

With manual brightness control and with the display of the white field in full screen, the maximum brightness value was about 330 cd / m², the minimum - 17 cd / m². The maximum brightness is low, and, given the disgusting anti-glare properties, readability on a sunny day outside the room will, in principle, be absent. In complete darkness, the brightness can be lowered to a comfortable value. In the presence of automatic brightness control by the light sensor (it is located to the left of the logo on the front panel). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. In total darkness, the auto-brightness function reduces the brightness to 55 cd / m2 (a bit too high), in an office lit with artificial light (about 400 lux) sets to 150 cd / m2 (normal), in a very bright environment (corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) increases to 330 cd / m² (to the maximum - this is what you need). It turns out that the automatic adjustment function works more or less adequately. At any brightness level, there is practically no backlight modulation, so there is no screen flickering either.

This smartphone uses an IPS-type matrix. On the photomicrograph, if desired, you can see the subpixel structure typical for IPS:

For comparison, you can see the gallery of photomicrographs of screens used in mobile technology.

At the same time, we present one more micrograph with focus on the film covering the matrix:

Visible dots are artificially created surface defects that create a matte finish. These defects are small relative to the subpixels, which leads to the practical absence of the characteristic "crystalline" effect.

The screen has good viewing angles without a significant color shift, even with large gaze deviations from the perpendicular to the screen and without inverting (except for the darkest when the gaze deviates along one diagonal) shades. For comparison, here are the photos in which the screens of Sony Xperia E4 Dual and Nexus 7 display the same images, while the brightness of the screens was initially set to about 200 cd / m² (along the white field in the entire screen), and the color balance on the camera was forced to 6500 K. Perpendicular to the screens white field:

Note the good uniformity of brightness and color tone of the white field. And the test picture:

Color reproduction is good and colors are saturated on both screens. Now at an angle of about 45 degrees to the plane and to the side of the screen:

It can be seen that the colors did not change very much on both screens, but the contrast in the Sony Xperia E4 Dual decreased to a greater extent due to the more highlighting of blacks and a significant decrease in brightness. And a white box:

The brightness at an angle at the screens decreased (at least 5 times, based on the difference in exposure), but in the case of the Sony Xperia E4 Dual, the drop in brightness is noticeably greater. When deviating diagonally, the black field is lightened to an average extent in absolute values, but very strongly, taking into account the drop in the overall brightness of the image. In this case, the black field acquires a violet or red-violet tint. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is about the same!):

And from a different angle:

With a perpendicular view, the uniformity of the black field is average, since along the edge in several places the black is slightly lightened:

The contrast (approximately in the center of the screen) is low - about 670: 1. The response time for the transition black-white-black is 29 ms (16 ms on + 13 ms off). The transition between gray tones of 25% and 75% (based on the numerical value of the color) and back takes 41 ms in total. The gamma curve, plotted using 32 points with equal intervals in terms of the numerical value of the shade of gray, did not reveal a blockage in either the highlights or the shadows. The exponent of the approximating power function is 2.03, which is below the standard value of 2.2, so the image is a little lightened. In this case, the real gamma curve slightly deviates from the power dependence:

The color gamut is close to sRGB:

The spectra show that the matrix filters moderately mix the components together:

As a result, the colors visually have a natural saturation. The balance of shades on the gray scale is acceptable, since the color temperature is close to the standard 6500 K, and the deviation from the spectrum of the absolute black body (ΔE) is less than 10, which is considered a good indicator for a consumer device. At the same time, the color temperature and ΔE vary little from shade to shade - this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)

This smartphone has the ability to correct the color balance by adjusting the intensities of the three primary colors. Which is what we tried to do, the result is data signed as Corr. in the graphs above. As a result, we significantly reduced ΔE on white and brought the white point a little closer to 6500 K. However, at the same time, catastrophic changes for the worse occurred on the rest of the gray scale. Yes, it's best not to interfere.

Let's summarize. The screen has a low brightness and has disgusting anti-reflective properties, which are deliberately spoiled by a matte film on the matrix. As a result, the device cannot be used outdoors on a clear day. In complete darkness, the brightness can be lowered to a comfortable level. It is also permissible to use a mode with automatic brightness adjustment, which works more or less adequately. The advantages of the screen include the absence of flickering, as well as a color gamut close to sRGB and an acceptable color balance. The significant disadvantages include the absence of an oleophobic (grease-repellent) coating, low stability of black to deviation of the gaze from the perpendicular to the plane of the screen and a strong decrease in the brightness of the image at an angle to the screen. In general, taking into account the importance of characteristics for this particular class of devices, the screen quality is low.

Sound

In terms of sound, the Xperia E4 Dual smartphone is quite simple and no different from its predecessor. There is only one speaker, the sound is unpretentious, dull, low frequencies are not noticeable, there is no richness of shades either, the smartphone sounds cheap, the maximum volume level is not great. In the conversational dynamics, the voice of the interlocutor, the intonation and timbre of the familiar voice remain recognizable, the voices sound natural and natural, there are no problems with this, it is quite comfortable to make phone conversations using the Xperia E4 Dual.

To play music, the device uses its own proprietary player, traditionally called the Walkman, but in terms of sound quality, the Xperia E4, like the entire budget line of Sony smartphones, is far from a musical solution. By default, you can use Clear Phase, xLoud or virtual surround sound enhancement technologies in the settings. Most of the settings are available when the complex ClearAudio + function is disabled, otherwise the sound is automatically controlled.

FM-radio is traditionally available as standard, but again there is no dictaphone. The radio does not know how to record programs and will not work without headphones connected as an external antenna. The smartphone is also unable to record telephone conversations from the line using standard means.

Camera

Sony Xperia E4 Dual is equipped with two digital camera modules with a resolution of 5 and 2 megapixels (the previous model of the series had the resolution of the front module limited to only 0.3 megapixels). Accordingly, the Xperia E4 has a much better front-facing module, and this is one of the most noticeable differences between generations in the lineup, especially for those who like to take photos in the style of selfies. Although, of course, there is no possibility of autofocus and its own front-facing flash, but the quality of the images obtained is much better than the front camera of the Xperia E3 did.

The main camera is equipped with a 5-megapixel module with an f / 2.6 aperture. Sony's proprietary automatic detection of shooting conditions detects up to 36 types of conditions and adjusts the parameters according to the selected one. This mode is set by default for the camera and it also enables or disables the HDR function depending on the conditions.

By default, the camera is standard for all Sony smartphones to shoot in automatic mode with the settings already set. To achieve the maximum resolution, as well as to be able to manually influence the settings yourself, you need to set the camera to manual mode. In addition to automatic and manual, the Sony Xperia E3 camera software has several shooting modes familiar from previous Sony models, such as Timeshift burst or an augmented reality mode called AR effect, which makes it possible to combine pictures with animation. There is a Social live function that allows you to immediately upload footage to social networks. With the help of a special online service, you can download and add other modes.

The camera can shoot video at a maximum resolution of 1920 × 1080, the video quality is modest.

• Movie # 1 (29 MB, 1920 × 1080, 30 fps)

	Good sharpness across the field and across plans. The shadows are too harsh and dark due to the narrow dynamic range, but they look good in places.
	The car number is distinguishable. The grain of the shumodava is large, but not very noticeable.
	Small branches are well worked out.
	Overall, the camera is not so bad at shooting indoors.
	Sometimes the camera copes with macro photography.
	The numbers of the nearest cars are distinguishable. Even in the distant shots, the sharpness is not bad.
	Judging by the shooting of the shield, the camera can handle the text quite well. Sometimes there is an out-of-focus area on the left side of the frame, as in this picture.

It turns out that a 5-megapixel camera can be quite good too. It is, of course, worse than the "ultrapixel" one (with the same formally resolution, HTC), but not much. If we close our eyes to the low resolution, then the camera can be considered good for a budget smartphone. The dynamic range is a bit narrow, so the shadows are quite harsh and mostly dark. Due to the low resolution, the grain of noise is noticeable, but it works out the details well. When shooting indoors, the camera does a good job, though not always. But it is worth noting separately good sharpness in the field of the frame and in the plans and attention to small details even at this resolution.

The camera is quite suitable for documentary shooting, and in some situations it will cope with artistic.

Telephone part and communications

The Xperia E4 Dual works as standard on modern 2G GSM and 3G WCDMA networks. There is also a modification of the Xperia E4g on sale with support for the fourth generation networks used in Russia (LTE Cat 4 with a theoretical speed of up to 150 Mbit / s), but not in the case of the hero of the review. In the modification that we tested, which works with two SIM cards, LTE is not supported, its wireless data transfer capabilities are limited to 3G mode (max HSDPA + speed up to 21 Mbps for downloading).

The rest of the network capabilities are also quite modest: there is no NFC support, the device does not support the second Wi-Fi band (5 GHz) either. The mode of connecting external devices to the USB port (USB Host, USB OTG) is also not implemented. The speed of the navigation module does not cause any particular complaints, but only the GPS network is supported, there is no domestic Glonass system and the Chinese Beidou (BDS) system. An element such as a magnetic field sensor, which is necessary for the operation of an electronic compass in navigation programs, is not built in either. In general, we can state that the network capabilities of the Sony Xperia E4 Dual are primitive today.

The smartphone supports dual SIM. However, there is no way to pre-assign any of the SIM-cards as the main one for organizing voice calls or sending SMS messages, this is only possible for data transmission. When dialing a number, it is always necessary to select the desired card in the contextual submenu. A SIM card in any slot can work with 3G networks, but only one of the cards can function in this mode at the same time. To change the assignments of the card slots, you do not need to change places - this can be done directly from the phone menu. There is only one radio module here, but Sony has implemented an automatic card-to-card forwarding function here, so it is possible to use two SIM cards at the same time. During a call on one SIM card, you can receive a call on another instead of redirecting it to voicemail. Thus, you can put one call on hold and answer the other. The same function called "Active mode" has already been encountered earlier in "dual-SIM" Samsung devices.

OS and software

The operating system is not the latest version of the Google Android 4.4.4 software platform. Above it is traditionally installed Sony's proprietary graphical user interface. The interface is standard, well known from the previous models of the manufacturer, nothing has changed here, in this regard, Sony does not have such a big gap between top and budget models, the interface of any smartphone from a Japanese company always remains uniform, familiar and familiar to everything. All branded services and pre-installed applications in their places.

Performance

The hardware platform of the Sony Xperia E4 Dual is based on the entry-level MediaTek MT6582 single-chip SoC. This outdated 32-bit and rather weak platform has 4 ARM Cortex-A7 cores operating at up to 1.3 GHz. The graphics are processed here by a low-power Mali-400MP video accelerator. The amount of RAM is 1 GB. Supports microSD memory cards up to 32 GB, there is no support for connecting external devices to the USB port in OTG mode.

About 5.5 GB (out of 8) is initially available in the device of its own memory for the needs of the user, and this is the biggest advantage of the new model over its predecessor Xperia E3. That amount of internal memory was limited to 1GB and it really was not enough even to install the most necessary applications. Here things are better with this.

According to the test results, the platform showed results that were expected to be very modest, below the average (~ 18K in AnTuTu). At this point, it is worth noting that the new product did not show the slightest progress in terms of increasing performance compared to the previous model Xperia E3 - the results of the old and new models in all tests are almost identical.

Now, if Sony built their new budget model on the MediaTek platform of a more recent generation, MT6732, which is also intended for entry-level smartphones, but already demonstrates incredibly high results for its class, then the model would clearly play with completely different colors. But this did not happen, and the smartphone, rather dull in appearance and capabilities, turned out to be equipped with the same dull, outdated and weak-powered platform. So, in terms of the level of performance of the hardware platform, the Sony Xperia E4 Dual smartphone cannot be attributed to the average level, this level is only initial by today's standards. The capabilities of the device are enough to perform basic organizational tasks, but we are not faced with a multimedia solution.

What would have happened if the Japanese had not been greedy to put a more recent MT6732 platform in their smartphone, clearly demonstrated by the review of the Elephone P6000. For comparison, we have placed the test results of this model in a comparison table. The result of the comparison does not require comments: the same budget, but incomparably more powerful 64-bit SoC MT6732 demonstrates one and a half, or even two times higher results than the outdated 32-bit MT6582 with its Cortex-A7 cores.

Testing with the latest AnTuTu and GeekBench 3 Benchmarks:

All the results obtained by us when testing the smartphone in the most recent versions of popular benchmarks, we have summarized in tables for convenience. Several other devices from different segments are usually added to the table, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within the framework of one comparison, it is impossible to present the results from different versions of benchmarks, therefore, many worthy and relevant models remain behind the scenes - due to the fact that they once passed the "obstacle course" on previous versions of test programs.

Testing the graphics subsystem in 3DMark gaming tests,GFXBenchmark, and Bonsai Benchmark:

When testing in 3DMark for the highest performing smartphones, it is now possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps).

Bonsai benchmark	1912 (27 fps)	3647 (52 fps)	2468 (35 fps)	1250 (18 fps)	2112 (30 fps)

Browser cross-platform tests:

As for benchmarks for evaluating the speed of the javascript engine, you should always make allowances for the fact that the results in them significantly depend on the browser in which they are launched, so that the comparison can be truly correct only on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

Video playback

To test the "omnivorous" video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that it is important for mobile devices to have support for hardware video decoding at the chip level, since it is often impossible to process modern versions using processor cores alone. Also, do not expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in a single table.

According to the test results, the subject was not equipped with all the necessary decoders that are needed to fully play most of the most common multimedia files on the network. To play them successfully, you will have to resort to using a third-party player - for example, MX Player. True, it is also necessary to change the settings and install additional custom codecs in it, because now this player does not officially support the AC3 audio format.

¹ the sound in MX Video Player was played only after installing an alternative custom audio codec; the standard player does not have such a setting

Further video playback testing was done by Alexey Kudryavtsev.

We did not find the MHL interface, like Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see "Testing methods for video playback and display devices. Version 1 (for mobile devices)" Red marks indicate possible problems related to the playback of the corresponding files.

According to the criterion for outputting frames, the quality of video files playback on the screen of the smartphone itself is good, since frames (or groups of frames) can (but are not required) to be displayed with uniform intervals of intervals and without frame drops. The exception is files with 60 fps, in which case two frames are dropped per second due to the screen refresh rate reduced to 58 Hz. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly on the edge of the screen. The brightness range displayed on the screen corresponds to the standard range of 16-235 - in the shadows only a couple of shades do not differ in brightness from black, but all the shades are displayed in the highlights.

Battery life

The non-removable battery installed in the Sony Xperia E4 Dual has even a slightly less capacious battery than the previous model with a volume of only 2300 mAh. The hardware platform in the smartphone is low-power, the screen has a low resolution - they are not too demanding in terms of energy resources. Accordingly, the device showed good battery life, but here it should be remembered that the hardware capabilities of this smartphone are not enough to adequately work out demanding multimedia tasks. And the previous model Xperia E3 turned out to be more advantageous in terms of power consumption in all tests without exception. It is also worth noting that the Xperia E4 Dual, like all other Sony smartphones, has a proprietary Stamina power saving mode.

Continuous reading in the FBReader program (with a standard, light theme) at the minimum comfortable brightness level (the brightness was set to 100 cd / m2) lasted about 13 hours until the battery was fully discharged, and while continuously watching YouTube videos (360p) at the same level brightness through the home Wi-Fi network, the device lasted 9 hours. In 3D games mode, the smartphone worked for 5 hours. Full charge time is almost 3.5 hours, because there is no proprietary fast charging technology, such as in Qualcomm platforms.

Outcome

If Sony approached the issue of creating last year's budget smartphone with imagination, at least providing its youth device with bright colors and an attractive design, then this is not observed in the next model. The next Xperia E series device turned out to be, perhaps, the most uninteresting in terms of appearance, if we recall the previous ones. bright and distinctive inexpensive representatives of the E series As for the characteristics and hardware capabilities of the smartphone, there is also nothing to boast about: the relatively large screen is not of high quality, the sound is also primitive, the network capabilities are primitive, the camera produces photos of modest quality, autonomy, contrary to expectations, not a record. On the other hand, a smartphone costs about 10-11 thousand rubles in official retail, this is not much at the current price level, and a product positioned for the entry-level, much of the above can be forgiven.

Specific Absorption Rate (SAR)

SAR levels refer to the amount of electromagnetic radiation absorbed by the human body when using a mobile device.

Head SAR (EU) The SAR level indicates the maximum amount of electromagnetic radiation that the human body is exposed to when holding a mobile device near the ear in a talking position. In Europe, the maximum SAR value for mobile devices is limited to 2 W / kg per 10 grams of human tissue. This standard was established by the CENELEC committee in accordance with the IEC standards, following the ICNIRP guidelines of 1998.	0.619 W / kg (Watts per kilogram)
Body SAR (EU) The SAR level indicates the maximum amount of electromagnetic radiation to which the human body is exposed if the mobile device is held at hip level. The highest SAR value for mobile devices in Europe is 2 W / kg per 10 grams of human tissue. This standard has been established by the CENELEC committee in accordance with the 1998 ICNIRP guidelines and IEC standards.	0.578 W / kg (Watts per kilogram)
Head SAR (US) The SAR level indicates the maximum amount of electromagnetic radiation that a person's body is exposed to when holding a mobile device near the ear. The maximum value used in the United States is 1.6 W / kg per gram of human tissue. US mobile devices are controlled by CTIA and the FCC conducts tests and sets their SAR values.	1.01 W / kg (Watts per kilogram)
Body SAR (US) The SAR level indicates the maximum amount of electromagnetic radiation to which the human body is exposed if the mobile device is held at hip level. The highest SAR value in the United States is 1.6 W / kg per gram of human tissue. This value is set by the FCC and CTIA monitors mobile devices for compliance with this standard.	0.77 W / kg (Watts per kilogram)
