Nokia X2 - Specifications. Nokia X2 - Specifications Information about navigation and positioning technologies supported by the device

Slightly grown and improved version of the "smartphone for Android applications"

Big changes swept through Microsoft's mobile division this summer. Nokia has done away with Asha's budget lineup. The software giant has ditched the ambitious McLaren project. And it was decided to transfer the Nokia X line to OS Windows Phone, ending all relations with the Android platform. But a little earlier, the manufacturer managed to present the second generation of these smartphones, which we will discuss in today's review.

The second Nokia model X no longer looks "gnawed" from all sides. Volume random access memory increased to a comfortable gigabyte, a front camera and flash appeared, a more powerful SoC was installed. But at the same time, the price increased, and by a noticeable for budget segment the amount.

Equipment

The Nokia X2 comes with the same set of accessories as its predecessor. Only the headphones have been repainted in regular black. "Bright Nokia X2" did not benefit from this.

By the way, the headset does not have a call acceptance button, so you will have to take your smartphone out of your pocket when you call. The cable for connecting to the PC is still missing.

Design

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

Main feature Nokia design The X2 is a two-layer casing made using the same technology as in the Nokia Asha 500/502/503. The bottom layer is made of colored polycarbonate. The upper one is made of an almost transparent polymer material, slightly tinted in the color of the lower layer.

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

Phones with a two-layer case are not widespread on the market, which allows Nokia X2 to win next to discreet neighbors in the shop window due to its originality.

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

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

The mechanical buttons have hardly changed, only the volume rocker is now split by a slot.

The Micro-USB connector has been moved from the bottom to the top, towards the headphone output. The 3.5mm jack is moved down, but its hole is covered by the outer layer of the case. The rest of the smartphone has no 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 Nokia X. After a few such manipulations, the colored cover starts to fit loosely and play in the lower left corner - the previous model was more reliable in this regard ...

Access to SIM1 and microSD is possible only with the battery removed. Please note that the sticker of the first model reads "Nokia", and here - "Microsoft Mobile".

The slot of the second SIM-card is located so that it can be accessible while the smartphone is in operation. 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. It is worth removing the back cover five or six times, and it already begins to fit loosely to the body, which can sometimes be heard even by ear. In general, the second version of the smartphone became more interesting both from an aesthetic and functional point of view, but there were no fundamental changes. Perhaps we will see more daring design moves with the transition of the series to Windows.

Screen

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 anti-glare properties of the screen are not worse than those of the screen Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens of both devices (Nokia X2 is on the right, then they can be distinguished by their size):

The screen of the Nokia X2 is even slightly darker (brightness in the photos is 99 versus 101 for the Nexus 7). The tripling of reflected objects in the Nokia X2 screen is very weak, which indicates that there is no air gap between the outer glass (aka the touch sensor) and the matrix surface ( screen type OGS - One Glass Solution). Due to the smaller number of boundaries (such as glass-to-air) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in the case of cracked outer glass is much more expensive, since the entire screen has to be changed. On the outside of the screen, there seems to be a special oleophobic (grease-repellent) coating, but its effectiveness is low therefore fingerprints appear quickly and require a relatively large amount of effort to remove.

With manual brightness control, 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-reflective properties, at bright daylight the image on the screen should be clearly visible. In complete darkness, the brightness can be lowered to a comfortable level. There is no automatic brightness control by the light sensor. The sensor between the front speaker and the camera can be mistaken for light-sensitive, but CPU-Z indicates that it is a proximity sensor.

At any brightness level, there is modulation of the backlight 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 screen flickering; 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 the individual, this modulation can lead to increased fatigue. Or it may not.

This screen uses matrix type IPS... The micrographs show the typical IPS subpixel structure:

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

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 shades when the gaze is deviated along one diagonal). For comparison, here is a photo in which the screens of Nexus 7 and Nokia X2 display the same images, while the brightness of the screens was initially set to about 200 cd / m2 (across the white field across the entire screen), and the color balance on the camera was 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 the 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 not changed much on both screens, but in Nokia X2 the contrast has decreased to a greater extent due to a greater decrease in brightness and strong lightening of black, and there is clearly added blue. And white box:

The brightness at an angle of both screens has noticeably decreased (at least 5 times, based on the difference in exposure), but in the case of Nokia X2 the drop in brightness is much greater. At the same time, the color tone of the white field on the Nokia X2 screen has slightly changed. When deviated diagonally, the black field is lightened strongly (especially taking into account the general drop in image brightness) and 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 the same for the screens):

And from a different angle:

With a perpendicular view, the uniformity of the black field is mediocre, since in several places along the edge the black is noticeably lightened, and the entire screen is in some spots in area:

Contrast (approximately in the center of the screen) is normal - about 700: 1. The response time for the transition black-white-black is 21 ms (10 ms on + 11 ms off). The transition between gray tones of 25% and 75% (based on the numerical value of the color) and back takes 32 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 either in highlights or shadows, and the exponent of the approximating power function turned out to be 2.15, which is insignificantly lower than the standard value of 2.2, while the real gamma the curve deviates little from the power-law dependence:

The color gamut differs slightly from sRGB:

The spectra show that the matrix filters mix the components together to a moderate extent:

At the same time, the coordinates of red and green colors are not very far from the corresponding vertices of sRGB, as a result, the colors of images - drawings, photographs and films - oriented to the sRGB space (and there are the overwhelming 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 spectrum of a black body (ΔE) is greater than 10 (due to the excess of 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 there is no color balance of great importance, 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-reflective properties, so the device can be used outdoors without any problems, even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable level. However, the brightness will have to be adjusted manually, since there is no automatic brightness adjustment mode. 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 - in visual assessment - color balance. The disadvantages - weak oleophobic coating, poor black stability to gaze deviation from the perpendicular to the plane of the screen, rapid drop in image brightness when viewed from an angle, not very good uniformity of the black field... 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 quality of the screen is a compromise, although not to say that it is bad.

Sound

The rear speaker in Nokia X2 seems to have been only slightly shifted, and this is where the innovations ended. The listening experience remained roughly the same as in the first model. Sound quality meets expectations from budget smartphones. No distortion appears at maximum volume.

As for the conversational dynamics, here some progress is noticeable. Nokia X2 no longer suffers from timbre distortions. But there is no need to dream about the crystal-clear communication characteristic of flagships.

You cannot record a conversation using a smartphone. There is an FM radio, which requires headphones to work.

Telephone part and communications

The Nokia X2 is equipped with two Micro-SIM slots, one of which is hot-swappable, which does not require rebooting the smartphone. Any of the cards can be assigned for data transmission, in this regard they are equivalent. Collaboration is organized in Dual Standby mode - both SIM cards are available in standby mode.

Wi-Fi 802.11 b / g / n is supported and the creation of 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 Chinese system Beidou. And immediately contacts them.

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

Camera

Nokia X2 has stepped far ahead in the possibilities of capturing photos and videos. The original model had a single camera with a resolution of only 3 megapixels. In the second version of the smartphone, it has grown to 5 megapixels and acquired a flash. In addition, a front-facing camera with a resolution of 0.3 megapixels appeared.

The main camera was commented on by Anton Soloviev:

	Sharpness according to plans is not bad.
	Shumodav processes noise only in weak shadows. In the strong, they are noticeable, but not striking.
	Despite some noise, the color of the sky is fairly even.
	On the right, you can see the out-of-focus area.
	The number of the nearest car is distinguishable, but more distant numbers are already impossible to make out.
	Sharping on wires is practically absent.
	The camera copes well with macro photography.
	The camera does a good job of writing, but not all characters are clearly legible.

For its 5 megapixel camera, the camera is not so bad, although it has a lot of problems. Shumodav tries to work as accurately as possible, and as a result produces practically no visible improvements. On the other hand, the sensor makes a rather "soft" noise, and the noise is not striking. The optics in the camera are pretty good. In some places, for some reason, there are areas of confusion, but in general, the images are quite sharp across the field and according to plans. In this case, the optics can work out more than the sensor can perceive. Nevertheless, the camera is quite good, but it does not work at all smoothly and will not cope with all the scenes. But shooting large text or general plans is within her power.

The maximum video resolution that the Nokia X2 camera is capable of is 1280 × 720.

The video is not very clear due to the low bit rate. However, if you remember that Nokia X shot a maximum of 352 × 288, progress is evident.

Software

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

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

It is easy to pre-install the driver and obtain Root rights through the utility. During installation, a request or two from the application will pop up on the phone - confirm them. Through Nokia X2 Tools you can install and Play Market... But in our case, it had a serious drawback: the program did not bind to account purchases. 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 out of it. After copying and changing permissions, restart your smartphone. Play Market is installed.

V new version Nokia X OS is even closer to the original Android. Now, by shifting from the top, you can call up two separate menus, with notifications and switches. This slightly expands the functionality, more icons are placed than before.

The Achilles' heel of the Nokia X was surfing the internet, which is 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 the drawing lagged behind by a split second, and even then on very loaded sites.

Performance

For the second generation Nokia X, Qualcomm's SoC was also chosen. From the base series of the next generation - Qualcomm Snapdragon S200, model MSM8210.

The central processing unit consists of two Cortex-A7 cores (ARMv7-A architecture) with a frequency of 1.2 GHz. For graphics, the Adreno 302 chip is used. The configuration is quite budgetary, you shouldn't have expected more from Nokia X2. Fortunately, the manufacturer has expanded the amount of RAM to one gigabyte, which cannot but affect the performance in a favorable way.

The performance boost allows the Snapdragon 200 to easily outperform the Antutu 4 Mediatek MT6572, which is very common in budget smartphones. The previous Nokia X was not capable of this. And 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 SoC demonstrates a decent result

Through the efforts Google chrome the Snapdragon 200 SoC beats that of Mediatek. Based on the hardware capabilities, Nokia X2 could swing at middling games, but the very small amount of internal memory does not allow it. It is worth installing a few third party applications to fill in the gaps of the firmware, and, for example, far from the most heavyweight Asphalt 8 will complain about the lack of memory. Fans of the X series continue to get only casual entertainment.

Video playback

We did not find the MHL interface, as well as Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the display 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 technique for video playback and display devices. Version 1 (for mobile devices)"). Screenshots with an exposure of 1 s helped to determine the nature of the frame output of video files with different parameters: the resolution varied (1280 × 720 (720p) and 1920 × 1080 (1080p) pixels) and the frame rate (24, 25, 30, 50 and 60 frames / With). In our tests, we used a stock video player. The test results are summarized in the table:

Note: If both columns Uniformity and Skips green ratings are set, this means that, most likely, when watching movies, artifacts caused by uneven alternation and skipping of frames 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 respective files.

If we restrict ourselves to the typical 24-25 fps for cinema, then according to the criterion for outputting frames, the quality of video playback on the screen of the smartphone itself is good, since frames (or groups of frames) can be displayed with a more or less uniform alternation of intervals and without frame drops. The displayed brightness range is equal to the standard range of 16-235, that is, in the shadows and highlights, all gradations of hue are displayed in the case of normal video files.

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

New budget platform Nokia X2 works well with all five common formats, whereas its predecessor could not even cope with 720p. Hardware decoding AC3 tracks are not supported.

Battery life

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

The battery consumption is not uniform throughout the entire discharge period; when calculating, it is worth adding about 6% of the time that the smartphone keeps on the last percent.

The autonomy of Nokia X2 has become more balanced compared to its predecessor. In reading mode, the smartphone lasts less, but it still does not yield to most competitors. But a more powerful SoC consumes more efficiently in more loaded modes, allowing you to increase the time autonomous work in games and during video playback. Charging a smartphone using the supplied adapter (5 V, 0.75 A) takes about four hours.

Conclusion

The Nokia X line continues to evolve. In the second version of the device, the functionality was expanded, the stability improved, and some annoying problems were fixed. Nokia X2 could boldly 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 the build quality spoiled the impression. Hopefully, the third version of the Nokia X will increase the flash storage to a viable 8GB, leaving Windows Mobile with something for the modest needs of the user.
