How to choose a mobile phone

Unlike the previous device, the new mobile phone is not so balanced. Its strengths and weaknesses will be discussed in this material.

Screen and camera

As in the first and second cases, the display diagonal is 2.2 inches. Its resolution is 320 pixels by 240 pixels. The number of displayed colors is 65 thousand. This is quite enough for comfortable work on such a device. The type of matrix used is TFT. This technology is already outdated today, but at the time of the device’s release it was relevant. But with the camera it turned out to be an absurdity. While its predecessor had a 5-megapixel matrix, and by this indicator the X2-00 even now surpasses some entry-level smartphone models, the Nokia X2-02 already uses 2 megapixels. You can't expect phenomenal quality from it. There is also the possibility of video recording in VZHA format. But the quality of the videos filmed also leaves much to be desired. So, in this regard, the previous model looks more preferable than the Nokia X2-02. Reviews from upset fans of taking pictures with their phones all over the Internet are further confirmation of this.

Mobile phone memory

Things are going well with the memory subsystem. The device itself has 64 megabytes integrated. But the user can only use a maximum of 10 of them. The rest is reserved by the system for its needs. In any case, you simply cannot do without a memory card. MicroSD flash drives with a maximum capacity of 32 GB are supported. The phone comes with a 2 GB card. Its volume is quite enough for comfortable work. You can put photos, videos and music tracks on it. If 2 GB is not enough for you, you will have to purchase an additional drive for the device.

What about the body?

If the X2-00 had a combined body, made of plastic and metal, then the new model had it entirely made of matte plastic. Therefore, you can’t do without a case and a sticker for the screen. Otherwise, in a year, maximum 2, you will have to buy a new case. On the front side of the device there are the following elements: a speaker, a screen and a regular telephone keypad. On the back there is a camera and a loud speaker. On the right there is a slot for installing a second SIM card. On the left, in turn, there is a slot for a memory card and a button for playing MP3 songs. It is immediately worth noting one advantage of such solutions from the designers of the Finnish company - without turning off the phone, you can replace both the 2nd SIM card and the microSD drive. Now let's figure out how to disassemble the Nokia X2-02. If the previous phone model had a special latch that opened the back cover, this phone does not have it. You just need to carefully tear it off with your fingernail. Under it there is a battery and a slot for installing the first SIM card.

Phone communications

An excellent set of communications from satisfied gadget owners on information resources confirms this. There is a round socket for charging the battery. A MicroUSB version 2.0 connector is provided for connection to a computer. The last 3.5 mm jack is intended for connecting an external audio system (speakers or headphones) to the device. The phone comes with a very mediocre stereo headset. Therefore, lovers of high-quality sound should buy headphones separately. Among wireless data transmitters, Bluetooth version 2.0 can be distinguished. But there is no Wi-Fi or GPS in this device. But taking into account the capabilities and positioning of the device, there is nothing to worry about. The existing communication capabilities are quite sufficient for normal, comfortable work on the Nokia X2-02. The characteristics in this regard are quite acceptable. A review of Nokia X2-02 will be incomplete if we lose sight of software optimization. According to the developers, if you use the built-in browser to view web pages, you can achieve a significant At the same time, their loading speed will increase.

Battery

The phone comes with a battery with a capacity of 1020 milliampere/hour. In this regard, the Nokia X2-02 cannot boast of anything unusual compared to similar devices from this manufacturer. Its installation scheme is usual. We removed the back cover, installed the first SIM card, turned the battery contacts to the contact group of the phone and installed it. If the battery becomes unusable, it can be easily replaced with a new one. But its capacity is enough for 2-3 days with active use. But this statement is true for a new battery. In a year or two it will lose capacity. It will already be enough for a day, maximum two. When listening to music, one charge is enough for 10 hours of continuous listening. In general, this mobile phone cannot boast of anything special in terms of battery and autonomous operation. But relatively recently the 1100 was released, which lasted 2 weeks on a single charge without any problems.

Let's sum it up

The Nokia X2-02 turned out to be somewhat ambiguous. Among the advantages, we can note support for 2 SIM cards in alternate switching mode. Otherwise, this phone is worse than its predecessor X2-00. And the camera is worse (2 MP versus 5 MP), and the body is completely plastic, and the battery provides less battery life. If you add complaints about certain “glitches” with the software, then it becomes really bad. And the answer to all these disadvantages is most likely hidden behind the name of the country of origin. If previously this Finnish brand was made only in Europe (Finland, Germany, Hungary and Romania), now Nokia’s main production facilities have been transferred to India. As a result, the quality has rapidly deteriorated. Nowadays it is almost impossible to buy such a phone new. Therefore, if you decide to buy such a gadget, you will need to try very hard to find it.

The second Nokia X model no longer looks “gnawed” from all sides. The amount of RAM increased to a comfortable gigabyte, a front camera and flash appeared, and a more powerful SoC was installed. But the price also increased, and by a noticeable amount for the budget segment.

Equipment

Nokia X2 comes with the same set of accessories as its predecessor. Only the headphones were repainted in the usual black color. This did not benefit the “bright Nokia X2”.

By the way, the headset does not have a call button, so when making a call you will have to remove the smartphone from your pocket. There is still no cable to connect to the PC.

Design

Externally, Nokia X2 is not much different from its predecessor. At first glance, the only thing that catches your eye is the additional “Home” button under the display, which has moved the “Back” button to the left.

The main design feature of the Nokia X2 is its dual-layer casing, made using the same technology as the Nokia Asha 500/502/503. The bottom layer is made of colored polycarbonate. The top one is made of almost transparent polymer material, slightly tinted to match the color of the bottom layer.

The original Nokia X looked like a toy, largely due to its simple plastic body. The second generation in this regard turned out to be much more interesting.

Phones with a double-layer casing are not common on the market, which allows the Nokia X2, due to its originality, to win next to its discreet neighbors in the store window.

The rear speaker is now centered. The flash is located above the camera.

A close examination of the lens and flash shows that the back cover does not fit well with the main part of the smartphone body.

The mechanical buttons have remained almost unchanged, only the volume rocker is now separated by a slot.

The Micro-USB connector has been moved from the bottom to the top, to the headphone output. The 3.5mm jack is moved down, but its hole is covered by the outer layer of the case. The remaining edges of the smartphone lack functional elements.

To open the smartphone, you need to press on the lower corners of the case and at the same time on the rear panel, just like in the Nokia X. After several such manipulations, the colored cover begins to fit loosely and play in the area of ​​the lower left corner - the previous model was more reliable in this regard .

Access to SIM1 and microSD is only possible with the battery removed. Please note that the sticker on the first model said “Nokia”, but here it says “Microsoft Mobile”.

The second SIM card connector is located so as to be accessible while the smartphone is in use. The “hot swap” function works perfectly here; the card is quickly detected by the phone on the go without rebooting. Another nice improvement in the series.

The build quality of the Nokia X2 is inferior to the original. Once you remove the back cover five or six times, it begins to fit loosely to the body, which can sometimes be detected even by ear. In general, the second version of the smartphone became more interesting both from an aesthetic and functional point of view, but no fundamental changes followed. Perhaps we'll see bolder design moves as the series transitions to Windows.

Screen

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 anti-glare properties of the screen are no worse than those of the screen Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photograph in which a white surface is reflected in the switched off screens of both devices (Nokia X2 is on the right, then they can be distinguished by size):

The screen of the Nokia X2 is even a little darker (brightness according to photographs is 99 versus 101 for the Nexus 7). The tripling of reflected objects in the Nokia X2 screen is very weak, this indicates that there is no air gap between the outer glass (also known as the touch sensor) and the surface of the matrix ( OGS type screen – One Glass Solution). 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. On the outer surface of the screen, It seems that there is a special oleophobic (grease-repellent) coating, but its effectiveness is low, so fingerprints appear quickly, and removing them requires relatively much effort.

When manually controlling the brightness, its maximum value was about 455 cd/m², and the minimum is 9 cd/m². The maximum brightness is high, and, given the good anti-glare properties, the image on the screen should be clearly visible in bright daylight. In complete darkness, the brightness can be reduced to a comfortable level. There is no automatic brightness adjustment based on the light sensor. The sensor between the front speaker and the camera can be mistaken for a light sensor, but CPU-Z shows that it is a proximity sensor.

At any brightness level, there is backlight modulation with rectangular pulses with an amplitude of 100% and a frequency of 300 Hz. At high brightness, the fill factor is high, almost 100%, so there is no flickering of the screen; when the brightness is lowered, the fill factor decreases, and flickering can already be noticed, for example, when the eyes (or the phone relative to the eyes) move quickly. Depending on individual characteristics, such modulation may lead to increased fatigue. Or maybe not.

This screen uses IPS type 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 view from perpendicular to the screen and without inversion (except for the very darkest when the view is deviated along one diagonal) of shades. For comparison, here are photographs in which identical images are displayed on the screens of the Nexus 7 and Nokia X2, with the screen brightness initially set to approximately 200 cd/m² (over a white field across the entire screen), and the color balance on the camera is forcibly switched to 6500 K. White field perpendicular to the plane of the screens:

Note the acceptable 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, but the color balance is slightly different. Now at an angle of approximately 45° to the plane and to the side of the screen:

It can be seen that the colors have changed slightly on both screens, but on the Nokia X2 the contrast has decreased to a greater extent due to a greater decrease in brightness and a strong brightening of blacks, and there has clearly been an increase in blue. And a white field:

The brightness at an angle for both screens has noticeably decreased (at least 5 times, based on the difference in shutter speed), but in the case of Nokia X2 the drop in brightness is significantly greater. At the same time, the color tone of the white field on the Nokia X2 screen has changed slightly. When deviated diagonally, the black field brightens greatly (especially taking into account the overall drop in image brightness) and acquires a violet or red-violet tint. The photographs below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same for the screens):

And from another angle:

When viewed from a perpendicular view, the uniformity of the black field is mediocre, since in several places along the edge the black is noticeably brightened, and the entire screen area is covered in some spots:

The contrast (approximately in the center of the screen) is normal - about 700:1. The response time for the black-white-black transition is 21 ms (10 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 32 ms. The gamma curve, constructed using 32 points with equal intervals according to the numerical value of the shade of gray, did not reveal a blockage either in the highlights or in the shadows, and the index of the approximating power function turned out to be 2.15, which is not significantly lower than the standard value of 2.2, while the real gamma the curve deviates little from the power law:

The color gamut is slightly different from sRGB:

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

At the same time, the coordinates of red and green colors are not very far from the corresponding sRGB vertices, as a result, the colors of images - drawings, photographs and films - oriented to the sRGB space (and the vast majority of them) have natural saturation and hue. The balance of shades on the gray scale is not ideal, since the color temperature is not much higher than the standard 6500 K, however, the deviation from the blackbody spectrum (ΔE) is more than 10 (due to excess green), which is considered not a very good indicator even for a consumer device. However, the variation in color temperature and ΔE is small, which has a positive effect on the visual perception of color balance. Dark 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.

Let's summarize. The screen has sufficiently high maximum brightness and has good anti-glare properties, so the device can be used outdoors without any problems, even on a sunny summer day. In complete darkness, the brightness can be reduced to a comfortable level. True, the brightness will have to be adjusted manually, since there is no mode with automatic brightness adjustment. The advantages of the screen include the absence of an air gap in the layers of the screen, a color gamut close to sRGB, and a good – when visually assessed – color balance. To the disadvantages - weak oleophobic coating, low black stability to gaze deviation from perpendicular to the screen plane, rapid drop in image brightness when viewed at an angle, not very good black field uniformity. We also note PWM brightness control with a frequency of 300 Hz, which can also be a disadvantage in case of individual intolerance. In general, the screen quality is a compromise, although not bad.

Sound

The rear speaker in the Nokia X2 seems to have been moved just a little, and that's where the innovation ends. The listening impressions remained approximately the same as in the first model. The sound quality is as expected from budget smartphones. At maximum volume, distortion does not appear.

As for the conversational dynamics, some progress is noticeable here. Nokia X2 no longer suffers from timbre distortion. But you shouldn’t dream about the crystal clear communication that is typical of flagships here.

A conversation cannot be recorded using a smartphone. There is an FM radio, which requires headphones to operate.

Telephone and communications

Nokia X2 is equipped with two Micro-SIM format slots, one of which supports the “hot swap” function, which does not require rebooting the smartphone. Any of the cards can be assigned for data transfer; in this regard, they are equivalent. Collaboration is organized in Dual Standby mode - both SIM cards are available in standby mode.

Supports Wi-Fi 802.11 b/g/n and creating an access point via Wi-Fi, USB and Bluetooth. Navigation in Nokia X2 works perfectly, in less than a minute it detects many satellites, not only GPS and Glonass, but also the Chinese Beidou system. And immediately contacts them.

USB OTG is not supported by the smartphone, but the small amount of memory can be expanded using microSD. Of the 4 GB of internal memory, 2.25 GB is available. Turning on the smartphone takes 50 seconds, which is much more than average.

Camera

Nokia X2 has made great strides in its photo and video capabilities. The original model had a single camera with a resolution of only 3 megapixels. In the second version of the smartphone, it grew to 5 megapixels and acquired a flash. In addition, a front camera with a resolution of 0.3 megapixels has appeared.

Anton Soloviev commented on the operation of the main camera:

	Sharpness according to plans is not bad.
	Noise reduction processes noise only in faint shadows. In strong ones they are noticeable, but not striking.
	Despite some noise, the color of the sky is quite even.
	On the right you can see an area of ​​blur.
	The license plate of the nearest car is distinguishable, but more distant license plates are no longer discernible.
	Sharping on the wires is practically absent.
	The camera copes well with macro photography.
	The camera can handle text well, but not all characters are clearly visible.

For its 5 megapixel camera, it’s not that bad, although it has a lot of problems. Noise reduction tries to work as carefully as possible, and as a result produces virtually no visible improvements. On the other hand, the sensor makes a fairly “soft” noise, and the noise is not noticeable. The optics in the camera are quite good. For some reason, areas of blur appear in places, but in general the pictures are quite sharp in the field and in the plans. In this case, the optics can work more than the sensor can perceive. Nevertheless, the camera is quite good, but it does not work smoothly and will not cope with all scenes. But she is capable of shooting large text or general plans.

The maximum video resolution that the Nokia X2 camera is capable of is 1280x720.

The video is not very clear due to the low bitrate. Although if you remember that Nokia X shot at a maximum of 352x288, progress is obvious.

Software

Nokia X2 runs the Nokia X2 2.0 operating system (apparently based on Android 4.3). It differs from the original OS installed in Nokia X only in appearance. The structure of the system remained unchanged. The main screen contains application shortcuts in the form of tiles, just like in Windows. Swiping left opens a list of all applications, while swiping right opens the Fastlane notification feed. The operating system, in general, works stably, but sometimes the interface slows down, especially when switching between applications and when setting up the desktop

Nokia and Yandex branded stores are available for installing applications. There is no Play Store. Moreover, you won't even be able to add a Google account to import contacts and other information. It's not difficult to fix this.

Pre-installation of the driver and obtaining Root rights can be easily done through the utility. During installation, a request or two from the application will pop up on your phone - confirm them. You can also install the Play Market through Nokia X2 Tools. But in our case, it had a serious drawback: the program did not link purchases to the account. Therefore, we used an alternative method.

Play Market is installed in much the same way as Google services in Ramos i10 Pro. You just need to copy all three files, including Vending.apk. And take them from this. After copying and changing permissions, restart your smartphone. Play Market is installed.

In the new version of the Nokia X OS, it has become even a little closer to the original Android. Now, by sliding from above, you can call up two separate menus, with alerts and switches. This somewhat expands the functionality; more icons can be placed than before

The Achilles heel of the Nokia X was Internet surfing, namely the very slow rendering of web pages. In the second version of the smartphone, the Opera browser is installed as standard. We've browsed a lot of web pages through it and Chrome. The impressions turned out to be much more pleasant; only in rare cases did the rendering lag by a split second, and even then on very busy sites.

Performance

For the second generation Nokia X, a single-chip system manufactured by Qualcomm was also chosen. From the base series of the next generation - Qualcomm Snapdragon S200, model MSM8210.

The central processor consists of two Cortex-A7 cores (ARMv7-A architecture) with a frequency of 1.2 GHz. The Adreno 302 chip is used for graphics. The configuration is very budget-friendly; you shouldn’t expect more from the Nokia X2. Fortunately, the manufacturer has expanded the amount of RAM to one gigabyte, which cannot but have a beneficial effect on performance.

The increase in performance allows the Snapdragon 200 to easily outperform the Mediatek MT6572, which is very common in budget smartphones, in Antutu 4. The previous Nokia X was not capable of this. But for Geekbench 3 there is not much difference: both SoCs have processor cores with the same characteristics. It is strange that twice the amount of RAM was not taken into account.

In synthetic 3DMark, the superiority over MT6572 becomes more than twofold. Even in the most demanding Epic Citadel mode, the Snapdragon 200 single-chip system demonstrates decent results

Thanks to the efforts of Google Chrome, the Snapdragon 200 single-chip system defeats the similar Mediatek. Based on its hardware capabilities, the Nokia X2 could be capable of playing mediocre games, but the very small amount of internal memory does not allow this. It is worth installing several third-party applications to fill in the gaps in the firmware, and, for example, the far from heavy Asphalt 8 will complain about a lack of memory. Fans of the X series still get only casual entertainment.

Playing video

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 different parameters: the resolution varied (1280 × 720 (720p) and 1920 × 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 frames/ With). In tests we used the standard video player. The test results are summarized in the table:

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 with the playback of the corresponding files.

If we limit ourselves to 24-25 frames/s typical for cinema, then 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 without skipping frames. The displayed brightness range is equal to the standard range of 16-235, that is, in the shadows and highlights all gradations of shades are displayed in the case of regular video files.

Let's try to reproduce five files of common formats.

The new budget Nokia X2 platform works well with all five common formats, while its predecessor could not cope even with 720p. Hardware decoding of AC3 tracks is not supported.

Battery life

The Nokia X2 battery capacity is 1800 mAh. The developers did not reach the round value, but this is already better than the modest 1500 mAh in the first modification.

Battery consumption is not uniform throughout the entire discharge period; when calculating, it is worth adding approximately 6% of the time that the smartphone remains at the last percent.

The autonomy of Nokia X2 has become more balanced compared to its predecessor. In reading mode, the smartphone lasts less, but is still not inferior to most competitors. But a more powerful SoC uses charge more efficiently in more loaded modes, allowing for longer battery life in games and video playback. Charging the smartphone from the supplied adapter (5 V, 0.75 A) takes about four hours.

Conclusion

The Nokia X line continues to evolve. The second version of the device expanded its functionality, improved stability, and fixed some annoying problems. Nokia X2 could easily compete on all fronts with more unsightly budget smartphones, but this is difficult due to the increased price. The list of competitive advantages of the device still includes the original design, although the deterioration in build quality spoiled the impression. We hope that in the third version of Nokia X the amount of flash memory will be increased to a viable 8 GB, and Windows Mobile will leave something of it for modest user needs.

TFT IPS- High quality liquid crystal matrix. It has wide viewing angles, one of the best indicators of color rendering quality and contrast among all those used in the production of displays for portable equipment.
Super AMOLED- if a regular AMOLED screen uses several layers, between which there is an air gap, then in Super AMOLED there is only one such touch layer without air gaps. This allows you to achieve greater screen brightness with the same power consumption.
Super AMOLED HD- differs from Super AMOLED in its higher resolution, thanks to which you can achieve 1280x720 pixels on a mobile phone screen.
Super AMOLED plus- this is a new generation of Super AMOLED displays, differs from the previous one by using a larger number of subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than displays made using the old PenTile technology.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display a larger color gamut, reduced thickness and the ability of the display to bend slightly without the risk of breaking.
Retina- high pixel density display designed specifically for Apple technology. The pixel density of Retina displays is such that individual pixels are indistinguishable to the eye at a normal distance from the screen. This ensures the highest image detail and significantly improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast reaches 1,000,000:1. The display has a wide color gamut and unsurpassed color accuracy. Pixels in the corners of the display are smoothed at the sub-pixel level, so edges are not distorted and appear smooth. The Super Retina HD reinforcing layer is 50% thicker. It will be harder to break the screen.
Super LCD is the next generation of LCD technology, it is characterized by improved characteristics compared to earlier LCD displays. The screens not only have wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal display. Using an active matrix controlled by thin-film transistors, it is possible to significantly increase the performance of the display, as well as the contrast and clarity of the image.
OLED- organic electroluminescent display. It consists of a special thin-film polymer that emits light when exposed to an electric field. This type of display has a large reserve of brightness and consumes very little energy.
