Alcatel one touch idol 2 white. An operating system is a system software that manages and coordinates the operation of hardware components in a device

Alcatel is becoming increasingly popular in the domestic market, and last year, sales of smartphones from this company were already equal to Huawei, LG and Fly. This manufacturer usually attracts users with a nice design along with fairly high performance. The new line of Idol smartphones can satisfy everyone's needs in terms of screen size, wireless capabilities, etc. A review of Alcatel One Touch Idol 2, the base model of the series, will show that the gadget is well thought out: big screen, high performance, stylish design - these are exactly the parameters that we pay attention to when purchasing.

Design and ergonomics

Taking a quick glance at the phone, it is difficult to distinguish it from some flagship models - it looks so good. The thin body with a thickness of 7.3 mm is captivating, so with a diagonal of 5 inches, the device does not look like a heavy shovel. The back panel is made of velvety plastic, and there is a chrome edging at the ends. In general, the device looks more than stylish and expensive.

The weight is the minimum possible - only 128 g, which, given the stated parameters, seems like a real gift. Thanks to this, thin frames around the display and small thickness, the gadget can be held with one hand, however, it will be more difficult to reach all corners of the display with the finger of the same hand.

It is noteworthy that the body is monolithic, assembly is high level, so even with strong pressure it is impossible to hear any squeaks. The location of the control keys is familiar and convenient; there are three touch buttons.

Alcatel Idol 2 appeared on display in different colors: white, gray, pink and brown. In any of these options it looks harmonious.

Screen

A 5-inch IPS screen is a significant advantage of a phone when a large diagonal becomes one of the most important selection criteria. The resolution is not very high – 540*960 pixels, which naturally affects the picture. But at a normal user distance this is not noticeable; the image remains clear and of high quality, and, most importantly, rich and contrasting, and does not fade when tilted.

To protect against damage, carbon fiber glass is used: the gadget can be safely carried in a pocket or bag without a case. For a budget device, the set of these characteristics is pleasantly surprising, so there’s nothing to complain about.

You can let the device itself control the brightness – it copes with this task just fine. We also note the sensitive display, which quickly responds to touch. In bright sunlight, the image fades a little, but you can still see the necessary information.

Performance and autonomy

Considering that the price of Alcatel Idol 2 is more than affordable, it is not surprising that it is standard for most budget smartphones MediaTek chipset MT6582M with a 4-core processor and a frequency of 1.3 GHz, RAM at 1 GB. The phone works quickly, quickly opens almost all applications, and there are no lags at all when watching videos or using standard programs. True, when launching resource-intensive games, there may be bouts of thoughtfulness, but this is forgivable.

Different versions have different amounts of main memory: 8 or 16 GB. In any case, the missing gigabytes can be realized using microSD cards.
There is only one SIM card in the gadget, but this is not surprising, because the body is monolithic. Wireless services include support for 3G, Bluetooth 4.0, Wi-Fi (plus access point mode) and even NFC. The navigator is wonderful, it finds satellites in 15 seconds with a hot start.

Idol 2 received a modest 2000 mAh battery, but it is nevertheless capable of providing full operation with many services and always-on Wi-Fi for a day or even more. Next, look at your usage scenario: if you don’t communicate much, and don’t surf the Internet often, then you can count on 2-3 days of work, and active users will receive a discharged gadget in the evening. These are standard indicators for an Android smartphone. Minimum charging time – 1.5 hours.

operating system– Android 4.2 with a proprietary shell from Alcatel: the manufacturer slightly redrew the icons in the menu and added a few of its own features. Otherwise, this is a typical operating system that is familiar to many, but upon purchase you get a device with a pre-installed package of useful applications.

Camera and sound Alcatel Idol 2

The main camera uses an 8-megapixel module with autofocus and flash, which is nice to see inexpensive smartphone. There are no complaints about the operation: focusing is fast and almost always accurate, the pictures come out decent, the menu is concise and understandable. Note that if you want to tinker with the settings before taking a photo, then Idol 2 is unlikely to suit you, since here manual settings little, but the “Auto” mode copes at a high level. The HDR and panorama modes familiar to many modern users are supported.

The video is recorded in a resolution of 1920*1080 pixels at a speed of 30 frames/s: the picture is clear, the sound is noise-free. The 2MP front camera takes decent selfies in optimal lighting levels.
The main speaker is very loud: you definitely won’t be able to miss a call, and the voice speaker ensures high-quality transmission of the interlocutor’s voice.

Results

Decent stylish compact and functional budget smartphones exist, and the review of One Touch Alcatel Idol 2 is another proof of this. For little money, everyone has a real chance to buy a solid phone with a large screen, thin body and excellent performance. Although the device has many competitors, in terms of the ratio of the filling to the external parameters, it is the best option in this price category.

Inexpensive model with support for 4G networks

When we mentioned the Chinese company TCL and its Alcatel brand, this year we first of all remembered the very noticeable top model of the TCL Idol X+ smartphone, which is based on the newest platform Mediatek with a maximum frequency of eight processor cores. However, with the release of one flagship model The company, naturally, did not limit itself in the new season: at the beginning of the year, during the MWC 2014 exhibition in Barcelona, ​​TCL presented a whole line of new mid-level smartphones, including Alcatel OneTouch Idol 2 and OneTouch Idol 2S and their various modifications. In accordance with the tradition that has emerged in the mobile market, the company could not help but release a version of the smartphone with the word “mini” in the name.

Such a device for the company was a reduced-size smartphone from the line mentioned above, which received a rather long and inconvenient name to pronounce: Alcatel OneTouch Idol 2 mini S. This small-sized smartphone is not a top-end device in terms of characteristics - it also belongs to the middle price level, like its “full-size” brothers in the line mentioned above. The domestic operator Beeline, for example, a few days ago introduced the Alcatel OneTouch Idol 2 mini S to the market as an exclusive offer: the smartphone itself is offered in the operator’s showrooms at a “tasty” price of 7,990 rubles, and in addition it comes with three months of free mobile internet. True, in this case, the buyer will have to sacrifice something: the Alcatel OneTouch Idol 2 mini S model purchased in Beeline stores is “locked” to work only with SIM cards of this operator and will not fully function with any other cards. In addition, the phone is stuffed to the brim with additional proprietary Beeline applications, as is usually the case, but this issue can be completely resolved using standard methods. But to make such a device work with SIM cards from other operators, you will have to find unconventional means - if anyone is even interested in such an option. Be that as it may, it is the modification of the smartphone offered by Beeline (6036Y) that is the maximum and best configuration of this model - it even has support for LTE networks, which at such a low price makes Idol 2 mini S one of the most inexpensive devices with 4G to our market. In any case, the described smartphone seemed to us a device quite interesting and worthy of making a full review of it.

Contents of delivery

In our case, we received a test copy of the Alcatel OneTouch Idol 2 mini S without packaging and, accordingly, a set of accessories, so we can judge the richness of the smartphone’s equipment only by the description on the company’s website. It states that in the box with a smartphone you can find a universal compact Charger, connecting Micro-USB cable, in-ear headphones and user manual.

Among the additional accessories purchased separately, we can note a book case with a unique built-in event indicator, made in the form of perforated illuminated icons - it looks nice and is probably not too energy-consuming. Without opening the lid, the user can receive information about incoming SMS messages, mail, incoming calls, etc.

Appearance and ease of use

In design and shape, the Alcatel OneTouch Idol 2 mini S smartphone resembles previous products in the Idol series; most of all, it is similar to the first flagship Idol X, which users liked so much at one time. To a lesser extent, it is similar to the updated Idol X+, although common design features can be traced here.

The smartphone has a rather small-sized, elegant and thin body that fits perfectly into the average hand. The device has rather slippery glossy side edges, but due to the matte non-slip back surface, as well as its small dimensions and weight, the smartphone is comfortably held in the palm of your hand. The size of the device is slightly larger than Apple iPhone- more similar to another compact modern model, Sony Xperia Z1 Compact.

The entire body of the Alcatel OneTouch Idol 2 mini S is made entirely of plastic, there is no metal here. The body has a monoblock structure, back cover has a slight bend and a matte, non-marking surface, which has a beneficial effect on both ergonomics and neatness general view devices. The side edges are made to look like chromed metal, but this is not real metal, but just a coating on the same plastic. The edges of the case have practically no bevels; they are quite wide and slippery to the touch.

From this structure of the case comes the corresponding method of installing a SIM card: the card, in the same way as in previous models of the Idol series, is inserted into the side slot, which is covered on top with an unusual cover. This cover does not need to be removed with a special needle-clip; it opens like a door on hinges. To open it, you need to press one end of the lid and push it inward. In principle, this method of opening was quite convenient for the full-size representatives of the Idol series, but in the smaller model all these elements also turned out to be reduced in size, making it not very convenient to manipulate these miniature lids. In this case, you have to use something sharp to press one end of the lid. You have to do the same with the card itself - the usual length of the nail is not enough to sink the SIM card to the depth required for capture.

The adjacent slot for installing a memory card has exactly the same structure - microSD cards up to 32 GB are supported. Both lids have short leads; they can be pulled out quite a bit so that they do not interfere with the installation of cards. In general, the whole process is quite uncomfortable; the method of installing cards in the Alcatel OneTouch Idol 2 mini S is far from the most convenient.

On the back of the smartphone, all the elements are familiar and arranged in the traditional order: on top there are the eyes of the camera and LED flash, on the bottom there is a row of holes for sound output from the ringing speaker.

The speaker grille overlaps the surface of the table, which partially muffles the sound of a lying smartphone. The single-section LED flash has pre-installed software to control it as a flashlight.

On the front surface, almost the entire front panel is covered with flat protective glass without edges; a hole is cut out in it for a large shiny chrome-plated hearing speaker grille; the eyes of the front camera and sensors are visible nearby.

Below the screen there is space left for hardware buttons to control the system and applications. These buttons are touch sensitive and have a white backlight of medium brightness, for which there was no item in the menu to adjust it.

There are only two mechanical hardware keys on the sides of the device, and both of them are located on the right side, one next to the other. The volume and lock keys have a fairly short travel, are small in size and protrude quite a bit beyond the body. In general, the implementation of controls is not the best, but you can get used to it.

The Micro-USB connector is placed at the bottom end - next to the microphone hole. The headphone output is implemented at the top end; nearby you can see the hole for the second, auxiliary microphone.

The smartphone connectors are not covered with any plugs or covers, because the device is not protected from water and dust. There was no hook on the case to attach the strap.

The product traditionally goes on sale in several color options: there are options in light gray and dark gray shades, and there are also pink and chocolate options. In different versions, the front panel under the glass of the smartphone also turns out to be of different colors: for example, in the chocolate version it is black, while in the others it is white.

Screen

The Alcatel OneTouch Idol 2 mini S smartphone is equipped with an IPS touch matrix. The physical dimensions of the display are 56x99 mm, diagonal - 4.5 inches. The screen resolution in pixels is 960×540, the dots per inch density reaches 245 ppi.

The display brightness has both manual and automatic adjustment, the latter based on the operation of the light sensor. The smartphone also has a proximity sensor that blocks the screen when you bring the smartphone to your ear. Multi-touch technology allows you to process 5 simultaneous touches.

Detailed examination using measuring instruments conducted by Alexey Kudryavtsev, editor of the “Monitors” and “Projectors and TV” sections. Here is his expert opinion on the screen of the sample under study.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface that is scratch-resistant. Judging by the reflection of objects, the anti-glare properties of the screen are no worse than those of the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the switched off screens (on the left - Nexus 7, on the right - Alcatel Idol 2 Mini S, then they can be distinguished by size):

The screen of the Alcatel Idol 2 Mini S is even a little darker (brightness according to photographs is 84 versus 92 for the Nexus 7). The ghosting of reflected objects in the Alcatel Idol 2 Mini S 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 - One Glass Solution type screen). Due to the smaller number of boundaries (glass-air type) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in the case of cracked external glass is much more expensive, since the entire screen has to be replaced. The outer surface of the screen has a special oleophobic (grease-repellent) coating (very effective, much like the Nexus 7), so fingerprints are removed much more easily and appear at a slower rate than with regular glass.

When manually controlling the brightness and displaying the white field in full screen, the maximum brightness value was about 500 cd/m², the minimum was 42 cd/m². The maximum brightness is very high, and, given the excellent anti-glare properties, readability even on a sunny day outdoors will be at a high level. In complete darkness, the brightness can be reduced to a comfortable value. There is automatic brightness adjustment based on the light sensor (located in the upper left corner on the front panel). IN automatic mode When external lighting conditions change, the screen brightness both increases and decreases. In complete darkness in automatic mode, the brightness is reduced to 42 cd/m² (acceptable), in an artificially lit office (approximately 400 lux) the brightness is set to approximately 500 cd/m² (this is the maximum and excessively bright), in a brightly lit environment (corresponding to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) - increases to the same 500 cd/m². As a result, the auto-brightness function does not work adequately for external conditions, and the whole point is in the software implementation, since the light sensor itself shows quite plausible results. At any brightness level, there is virtually no backlight modulation, so there is no screen flickering.

This smartphone uses an IPS matrix. The microphotographs show a typical IPS subpixel structure:

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

The screen has good viewing angles without a significant color shift even with large deviations of the gaze from perpendicular to the screen and without inverting (except for the very darkest when the gaze is deviated to the right) shades. For comparison, here are photographs in which the same images are displayed on the screens of Alcatel Idol 2 Mini S and Nexus 7, while the screen brightness is initially set to approximately 200 cd/m² (across the white field in full screen), and the color balance on the camera is forcibly switched to 6500 K. White field perpendicular to the screens:

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

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

It can be seen that the image quality at this angle on the Alcatel Idol 2 Mini S screen has noticeably deteriorated. And a white field:

The brightness of the screens at an angle has decreased (by at least 6 times, based on the difference in shutter speed), but the Alcatel Idol 2 Mini S has a noticeably darker screen. When deviated diagonally, the black field is lightened to a medium degree and acquires a purple tint. The photographs below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is approximately the same!):

And from another angle:

When viewed perpendicularly, the uniformity of the black field is average, since there are areas with increased black brightness along the edge of the screen:

The contrast (approximately in the center of the screen) is not the highest - about 680:1. The response time for the black-white-black transition is 24 ms (13 ms on + 11 ms off). The transition between halftones of gray 25% and 75% (based on the numerical value of the color) and back takes a total of 38.5 ms. The gamma curve, constructed using 32 points with equal intervals based on the numerical value of the shade of gray, did not reveal any blockage in either the highlights or the shadows. The exponent of the approximating power function is 1.86, which is lower than the standard value of 2.2. In this case, the real gamma curve strongly deviates from the power-law dependence:

Such a deviation is usually a sign of the presence of dynamic adjustment of the backlight brightness in accordance with the nature of the output image (since the measurements were carried out with sequential output of shades of gray almost to the entire screen), but we did not receive additional evidence of its existence. But just in case, we carried out a number of tests - determining contrast and response time, comparing black illumination at angles - when displaying special templates with a consistently average brightness, and not monochromatic fields in the entire screen.

Color gamut is close to sRGB:

The spectra show that the matrix filters moderately mix the components with each other:

As a result, visually the colors have a natural saturation. The balance of shades on the gray scale does not cause any particular delight, since the color temperature is noticeably higher than the standard 6500 K, the deviation from the spectrum of an absolutely black body (ΔE) is less than 10, which is considered a good indicator for a consumer device, however, ΔE varies significantly from shade to shade - this negatively affects the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)

To summarize: the screen has a high maximum brightness and has good anti-glare properties, so the device special problems You can use it outdoors even on a sunny summer day. In complete darkness, the brightness can be reduced to a comfortable level. The mode with automatic brightness adjustment is practically useless, since already in a lit room it increases the brightness to the maximum, which, of course, leads to unnecessary energy consumption. Significant advantages of the screen include an effective oleophobic coating, the absence of air gaps in the layers of the screen and flicker, as well as the sRGB color gamut. The remaining characteristics are not outstanding, but not disastrous either. In general, taking into account the importance of characteristics for this particular class of devices, the screen quality can be considered high.

Sound

In terms of sound, the smartphone is nothing special. Both speakers produce a fairly clean sound, but without noticeable presence. low frequencies The sound is also not loud enough. However, this does not particularly affect the perception of sound during a conversation - the voice of a familiar interlocutor, timbre and intonation remain recognizable. The settings include standard equalizer capabilities with preset values ​​and some additional effects.

The device can use built-in tools to record a conversation from the line, both talking parties are recorded, and the recorded files are automatically stored in the appropriate folder. The smartphone is equipped with a built-in FM radio, which traditionally only works with headphones connected as an external antenna.

The main rear camera here has an 8-megapixel module and shoots with a maximum resolution of 3264 × 1836. The quality of the images is average, most often the photos come out overexposed and slightly blurry. The settings are quite clearly laid out and conveniently arranged, but the capabilities contained here are quite modest.

The camera can shoot video at a maximum resolution of 1080p (30 fps), examples of test videos are presented below.

• Video #1 (35 MB, 1920×1080, daylight)
• Video #2 (33 MB, 1920×1080, indoors)
• Video No. 3 (18 MB, 1920×1080, at night)

Examples of photographs with our comments are presented below.

	The sharpness in distant shots is quite good.
	The camera cannot fully resolve foliage, but overall it does a good job.
	Sharpness across the frame is fairly uniform.
	In the background, the foliage hardly blends together.
	Noise in the shadows is not so strong, and, apparently, well processed.
	The camera performs relatively well indoors.
	Even when shooting at night, the camera does not show such bad results.
	The camera also copes well with macro photography.

What we have in front of us is exactly what can be safely called a balanced camera. Let's start with the fact that the camera simply does not have any significant shortcomings. It copes with its 8 megapixels, perhaps not perfectly, but very well. The camera has a good sensor, good optics and moderate software processing. It is all these three parameters in symbiosis that give the camera that very balance. The sensor copes well in the shadows, so the noise reduction does not need to be reworked. The optics process the image well across the field of the frame and across the plans, so there is virtually no sharpening in the images. Oddly enough, the camera’s merits are not limited to this: it works quite well in low light. The camera resorts to sensitivity values ​​above ISO 100 only when absolutely necessary, but even a night shot (ISO 232, 1/17 second) demonstrates relatively good performance.

As already mentioned, the camera turned out to be good and balanced and is quite suitable for most scenes.

Telephone and communications

The smartphone works as standard in modern 2G GSM and 3G WCDMA networks, and also supports networks used in Russia fourth generation(4G). With a SIM card from the domestic operator Megafon, the smartphone in practice confidently finds and works with the LTE network. The data transfer speed, accordingly, in theory can reach up to 150 Mbit/s of incoming traffic. Among additional network capabilities, support is available. Mode for connecting external devices to USB port(USB Host, OTG) is, unfortunately, not supported here, so flash drives connected via an OTG adapter will not be recognized. The navigation module supports both GPS and domestic Glonass and works very clearly and quickly, there are no problems with this.

There were no spontaneous reboots/shutdowns observed during testing, as well as system slowdowns or freezes. The LED notification sensor here modestly shines as a small whitish dot in the upper left corner of the front panel, unobtrusively signaling various incoming events. The light sensor adjusts the brightness level automatically, but does not do it entirely correctly.

The drawing of letters and numbers on virtual keyboards is quite small and not very comfortable to operate. The layout and location of the keys is standard: switching languages ​​here is done by pressing special button with an image of a globe, there is no separate row with numbers - you need to switch the layout each time. The phone application supports Smart Dial, that is, while dialing phone number A search in contacts is also carried out immediately.

OS and software

Alcatel OneTouch Idol 2 mini S currently runs on the Google Android software platform, which is not the latest version 4.3. The proprietary shell, stretched over the standard Android interface, here has a fairly heavily redesigned and expanded functionality: sections have been added to the settings menu, there are rudiments of gesture support, and even the ability to unlock the screen by tapping has appeared. In general, everything is very familiar from previous models of the Idol series. The application menu is present in this user interface, most of them are already pre-installed applications carefully arranged into thematic folders by the developers themselves. Creation of folders/groups is supported on desktops.

As mentioned above, our test laboratory included a modification of the smartphone, branded specifically for the Beeline operator, with all the ensuing consequences. The smartphone interface not only has special themes with the familiar black and yellow coloring, but is also crammed with a mass of all kinds of proprietary applications, which in general are not of particular interest. However, it is not difficult to return the appearance of the interface to its original, calmer appearance. In our case, to test all the capabilities of the device, it was also unlocked, and after that it worked perfectly with SIM cards from other operators, and even registered in LTE networks.

Performance

The Alcatel OneTouch Idol 2 mini S hardware platform is based on a single-chip system (SoC) Qualcomm Snapdragon 400 (MSM8226). The central processor here has 4 ARM Cortex-A7 cores operating at a frequency of 1.2 GHz, although the maximum possible frequency here is up to 1.6 GHz (SoC production technology is 28 nm). Random access memory The device has 1 GB, and the storage available to the user for uploading their own files is about 5 GB of the nominally designated 8 GB - the rest is spent on the system itself and applications. Memory can be expanded using microSD cards up to 32 GB. Unfortunately, you won’t be able to connect a flash drive via an OTG adapter - the device this mode do not support.

To get an idea of ​​the performance of the platform of the smartphone under test, we will conduct a standard set of tests. We have already tested devices based on the MSM8226 SoC: a recent and very recent example is the LG G2 mini, which operates on exactly the same platform. For comparison, let's take the results of the same platform, but with a slightly faster core frequency (1.4 GHz, Asus Padfone E model), and also add the results of another similar platform from Qualcomm - Snapdragon 200, which has exactly the same cores and their number the same, but the SoC itself is made using 45 nm technology. This relatively new budget platform is called Snapdragon 200 (MSM8212), and we tested it using an example Huawei smartphone Ascend G6, which is currently being heavily advertised on television, and a review of which is also being prepared for release.

For convenience, we have compiled all the results we obtained when testing the smartphone in the latest versions of popular benchmarks into tables. The table usually adds several other devices from different segments, also tested on similar latest versions benchmarks (this is done only for a visual assessment of the obtained dry figures). Unfortunately, within the framework of one comparison it is impossible to present the results from different versions benchmarks, so many worthy and relevant models remain “behind the scenes” - due to the fact that at one time they passed their “obstacle courses” on previous versions test programs.

Based on the test results, it is clear that the Snapdragon 400 MSM8226 SoC, made using a 28 nm process technology, turned out to be slightly faster in all respects than the Snapdragon 200 MSM8212 SoC, manipulating the same cores, but made using a 45 nm process technology (Huawei G6 platform). The results of the LG G2 mini turned out to be identical, which is logical, because they have the same platforms, and the slightly faster cores of the Asus Padfone E showed a slight superiority, which is also quite logical and meets our expectations.

In general, according to the results of all tests, the Alcatel OneTouch Idol 2 mini S smartphone can be safely classified as a device with average, or even slightly above average performance. At the moment, the hardware performance of this smartphone should be enough to perform most tasks that can be performed by any games or other applications from Google Play Store.

Test results in MobileXPRT, as well as the latest versions of AnTuTu 4.x and GeekBench 3:

When testing the graphics subsystem in the cross-platform 3DMark test for the most powerful smartphones, it is now possible to run 3DMark 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).

Playing video

To test the omnivorous nature of 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 Internet. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern options using processor cores alone. Also, you shouldn’t 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 testing results, Alcatel OneTouch Idol 2 mini S was not equipped with all the necessary decoders, in this case audio ones, which are necessary for full playback of most of the most common files on the network. To successfully play them, you will have to resort to the help of a third-party player - for example, MX Player. True, even in it you will have to first change the settings, switching from hardware decoding to software or new mode entitled Hardware+(not supported by all smartphones), only then will sound appear. All results are summarized in a single table.

Format	Container, video, sound	MX Video Player	Standard video player
DVDRip	AVI, XviD 720×400 2200 Kbps, MP3+AC3	plays normally	plays normally
Web-DL SD	AVI, XviD 720×400 1400 Kbps, MP3+AC3	plays normally	plays normally
Web-DL HD	MKV, H.264 1280×720 3000 Kbps, AC3	Hardware+
BDRip 720p	MKV, H.264 1280×720 4000 Kbps, AC3	plays fine with decoder Hardware+	The video plays fine, but there is no sound¹
BDRip 1080p	MKV, H.264 1920×1080 8000 Kbps, AC3	plays fine with decoder Hardware+	The video plays fine, but there is no sound¹

¹ MX Video Player only played sound after switching to software decoding or a new mode Hardware+; The standard player does not have this setting

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 “Method for testing video playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output of frames of video files with various parameters: the resolution varied (1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 frames/ With). In the tests, we used the MX Player video player in the “Hardware+” mode. The test results are summarized in the table:

Fine No Fine No Fine No Fine No

Note: If in both columns Uniformity And Passes Green ratings are given, this means that, most likely, when watching films, artifacts caused by uneven alternation and frame skipping will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problems related to the playback of the corresponding files.

In general, according to the criterion of frame output, the quality of playback of video files on the screen of the smartphone itself is good, since frames (or groups of frames) can be output with more or less uniform alternation of intervals and, with rare exceptions, without skipping frames. When playing 720p and 1080p video files with an aspect ratio of 16:9, the image of the actual video file is displayed exactly along the edge of the screen. The brightness range displayed on the screen corresponds to the standard range of 16-235 - all gradations of shades are displayed in shadows and highlights.

Battery life

The capacity of the lithium-ion battery installed in the Alcatel OneTouch Idol 2 mini S is 2000 mAh, small for a modern smartphone. However, according to the test results, the test subject did not lose face, demonstrating a very respectable time battery life in a variety of standard use cases. The device even outperformed most of its direct competitors in this regard, except for mini-models from Samsung and LG - modern Korean smartphones have recently demonstrated the best optimization performance in terms of energy consumption.

Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted almost 16 hours until the battery was completely discharged. When continuously watching YouTube videos in high quality (HQ) with the same brightness level through your home Wi-Fi network The device lasted about 9 hours, and in 3D gaming mode - about 4 hours. The smartphone charges quite quickly: a full charge takes less than 2 hours.

Bottom line

As for the cost of the Alcatel OneTouch Idol 2 mini S - or rather, the best configuration of this device (6036Y), with support for LTE and NFC, which we tested, it is offered on the domestic market only as a branded device of the domestic operator Beeline. Such a smartphone costs 7,990 rubles - this is a couple of thousand more than the previous mini-model of the Alcatel Idol series, which was recently advertised on television by actor Konstantin Khabensky. And yet, even this price seems quite acceptable for such a nice, compact, but quite powerful and technically advanced device of a solid mid-level. For small money by the standards of the domestic market, the user receives a very high-quality product with high-quality materials, unquestionable assembly, efficient hardware, and a well-designed screen for its level, which allows the device itself to remain within a comfortable frame for the hand. Finally, we can state that not only among the “shovels”, very high-quality ones that meet the majority of modern technical requirements mobile devices such as the Sony Xperia Z1 Compact or the even more affordable hero of today’s review - the Alcatel OneTouch Idol 2 mini S smartphone.

Alcatel has increased its the lineup middle-class smartphones, updating the Idol 2 model. The device received a prefix to its name in the form of the letter “S”, learned to work in LTE networks and acquired a screen with a higher resolution. What came of it?

Exterior

Looking at the heir to the Idol line, we can conclude that Alcatel is working on the appearance of its products. Smartphones, although similar to each other, like representatives of the Lumia family, still become sleeker and more attractive with each generation. For a user accustomed to devices with large displays, the model with the serial number “2S” will seem compact. And although it is difficult to make a gadget miniature with a five-inch screen, the once popular French brand managed to narrow the frames around the screen so that the device could be comfortably used with one hand. The 2S is slimmer than its siblings: it is less than 7.5 millimeters thick and absolutely typical for touchscreen smartphones appearance. An unremarkable black glossy front panel with a silver earpiece and LED indicator and a slightly convex back cover. It has a matte metallic finish. The camera protruding above the body is located strictly in the center. It was decorated with a metal edging: the result was complete harmony with the logo.

The right side became a haven for the power button and changing the volume level; slots for microSD and SIM cards were placed on the left. To access them, you need to press on the convex point and move the plug. The speaker and microphone holes are symmetrically located on the bottom end near the microUSB connector, and the mini-jack is on the top.

The “Idol” case is non-separable, but has the same problem as most products in the ONETOUCH series - backlash. To be fair, it is worth noting that crunching when pressing on the back panel does not affect the operation of the smartphone, but can ruin the experience of use. But the device has retained a positive feature of the entire line: it’s about ergonomics.

In general, the appearance of the thin, light and rounded device deserves a positive assessment.

Display

The characteristics are quite modest: the IPS matrix has HD resolution and a diagonal of five inches. But the Idol 2S's screen is its advantage. The picture on the display with bright and saturated colors is practically not inverted when viewed at an angle; in comparison with other budget and middle-class devices, the smartphone has an advantage in terms of brightness reserve, although there are only three levels of its settings in the launcher. The oleophobic coating copes with fingerprints no worse than in expensive brothers in the line, for example, ONETOUCH Hero 2, which recently came to us on. And Idol is not afraid of sharp objects - the screen is protected by Dragontrail glass.

Performance

Practice proves that smartphones with budget hardware can also demonstrate decent performance indicators, because the key to everything is software and hardware optimization. In the case of Idol 2S, all the shortcomings are evident in the form of a lack of smoothness and numerous slowdowns in the interface, not to mention applications and games. Of course, high expectations from the operation of a smartphone in price segment it can’t be up to ten thousand rubles, but the gadget doesn’t justify its earned 17,000 points in the Antutu benchmark. Perhaps the root of evil that has sprouted in 2S and prevents it from thinking faster is the obsolete Android 4.3 JellyBean in its modified version. System processes occupy more than 600 MB of the available 1 GB. Available space on internal storage- 5.4 GB, but using a microSD memory card you can get up to an additional 32 GB.

The autonomy of the device with a built-in 2150 mAh battery is above average. With moderate use, Idol will easily last 12 hours. Watching a video on a five-inch screen will lead to complete exhaustion in 5.5 hours. You couldn't ask for more in an affordable B-brand product. The 2S also has another quality that is rare for its class: support for LTE Cat.4, which allows you to download data to the device at speeds of up to 150 Mbit/s. The variation called 6050Y has NFC.

Camera

Photographic ability will not be included in the Idol 2S talent list. The main camera should take pictures with a size of 8 megapixels, but in the standard application the maximum available size- only 6 megapixels. The front module allows you to take photographs at a modest 1.3 megapixels, which is enough for video conversations, but not enough to create highly detailed self-portraits. There is a set of settings with a choice of timer, exposure and ISO, as well as HDR, sports, smile detection in the frame, night shooting and creating panoramas.

Even in good lighting, the main camera cannot prove itself as an excellent assistant to a phone photographer. In photos taken indoors, noise is clearly visible; in the dark, you should not try to capture the lights of the night city even in the appropriate mode.

Conclusion

Because Alcatel ONETOUCH Idol 2S in domestic latitudes can only be purchased at the operator's showroom; it is obvious that the vendor does not count on mass sales. The smartphone's performance is enough to perform most of the tasks necessary for the average user, such as working with mail, communicating via in social networks and publishing photos there, non-resource-intensive games and watching videos. It demonstrates decent endurance, works in fourth generation networks and looks stylish. What else is needed for happiness? Problems with the case are easily solved by purchasing a case-pad. But will the buyer want to give preference to this model when there are dozens and hundreds of gadgets with almost identical characteristics in the budget device segment?

Accelerometer(or G-sensor) - sensor of the device’s position in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, G-sensor is used as a pedometer, it can be controlled various functions device by turning or shaking.
Gyroscope- a sensor that measures rotation angles relative to a fixed coordinate system. Capable of measuring rotation angles in several planes simultaneously. A gyroscope together with an accelerometer allows you to accurately determine the position of the device in space. Devices that use only accelerometers have lower measurement accuracy, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor that sets the optimal brightness and contrast values ​​for a given light level. The presence of a sensor allows you to increase the battery life of the device.
Proximity sensor- a sensor that detects when the device is close to your face during a call, turns off the backlight and locks the screen, preventing accidental clicks. The presence of a sensor allows you to increase the battery life of the device.
Geomagnetic sensor- a sensor for determining the direction of the world in which the device is directed. Tracks the orientation of the device in space relative to the magnetic poles of the Earth. The information received from the sensor is used in mapping programs for terrain orientation.
Atmospheric pressure sensor- sensor for precise measurement of atmospheric pressure. It is part of the GPS system, allows you to determine altitude above sea level and speed up location determination.
Touch ID- fingerprint identification sensor.

Satellite navigation:

GPS(Global Positioning System - global positioning system) - satellite system navigation, providing measurement of distance, time, speed and determining the location of objects anywhere on Earth. The system is developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine location by measuring distances to an object from points with known coordinates - satellites. The distance is calculated by the delay time of signal propagation from sending it by the satellite to receiving it by the antenna of the GPS receiver.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measurement principle is similar to the American system GPS navigation. GLONASS is designed for operational navigation and timing support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital motion do not have resonance (synchrony) with the rotation of the Earth, which provides them with greater stability.
