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

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

Nokia X2 offers

* - at the time of writing the corresponding article

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

Equipment

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

By the way, the headset does not have a call acceptance button, so when making a call, the smartphone will have to be removed from your pocket. The cable to connect to the PC is still missing.

Design

Externally, Nokia X2 is not much different from its predecessor. At first glance, only the additional Home button below the display catches the eye, moving the Back button to the left.

The main design feature of Nokia X2 is a two-layer case, made using the same technology as in Nokia Asha 500/502/503. The bottom layer is made of colored polycarbonate. The top is made of an 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 unsophisticated plastic casing. The second generation in this regard was much more interesting.

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

The rear speaker is now center aligned. The flash is placed above the camera.

A close examination of the lens and flash shows that the back cover is poorly fitted to the main body of the smartphone.

Mechanical buttons have not changed much, only the volume rocker is now divided by a slot.

The Micro-USB connector has been moved from the bottom to the top, to the headphone jack. The 3.5mm jack is moved down, but its hole is covered by the outer layer of the case. The remaining facets of the smartphone are devoid of 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 several such manipulations, the colored cover begins to loosen and play in 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. Note that the sticker on the first model said "Nokia", but here it says "Microsoft Mobile".

The slot for the second SIM card is positioned so as to be accessible even while the smartphone is running. 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 takes five or six times to remove the back cover, and it already begins to loosely adhere to the body, which can sometimes be caught even by ear. In general, the second version of the smartphone has become more interesting both from an aesthetic and functional point of view, but there have been no fundamental changes. Perhaps we will see bolder 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 off screens of both devices (Nokia X2 is on the right, further they can be distinguished by size):

The screen of the Nokia X2 is even a little darker (brightness from photos is 99 versus 101 for the Nexus 7). The tripling of reflected objects on the Nokia X2 screen is very weak, which indicates that there is no air gap between the outer glass (it is also a touch sensor) and the matrix surface ( OGS type screen - One Glass Solution). Due to the smaller number of borders (glass-air type) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be changed. 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 relatively much effort is required to remove them.

With manual brightness control, its maximum value was about 455 cd/m², and the minimum 9 cd/m². The maximum brightness is high, and given the good anti-reflective properties, the image on the screen should be clearly visible in bright daylight. In complete darkness, the brightness can be lowered to a comfortable level. There is no automatic brightness control by light sensor. The sensor between the front speaker and the camera can be mistaken for a photosensitive one, 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 flicker can already be seen, for example, when moving the eyes (or the phone relative to the eyes) quickly. Depending on individual characteristics, such modulation can lead to increased fatigue. Or maybe not lead.

This screen uses IPS type matrix. Micrographs 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 significant color shift even with large deviations of the view from the perpendicular to the screen and without inverting (except for the very darkest when the view is deviated along one diagonal) shades. For comparison, here is a photograph in which the same images are displayed on the screens of the Nexus 7 and Nokia X2, while the brightness of the screens was initially set to about 200 cd / m² (across the white field in full screen), and the color balance on the camera was forcibly switched to 6500 K. Perpendicular to the plane of the screens is a white field:

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

Color reproduction is good and colors are saturated 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 on the Nokia X2, the contrast has decreased to a greater extent due to a greater decrease in brightness and a strong lightening of black, and blue has clearly been added. And the white box:

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 much greater. At the same time, the color tone of the white field on the Nokia X2 screen has changed somewhat. The black field, when deviated diagonally, is highlighted strongly (especially considering the overall decrease in image brightness) and acquires a purple or red-violet hue. 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:

With 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 is covered in some spots:

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 25% and 75% grayscale (according to the numerical value of the color) and back takes a total of 32 ms. The gamma curve constructed from 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 exponent of the approximating power function turned out to be 2.15, which is slightly lower than the standard value of 2.2, while the real gamma the curve deviates slightly from the power dependence:

The color gamut is slightly different from sRGB:

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

At the same time, the coordinates of red and green colors are not very far from the corresponding sRGB peaks, 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 black body spectrum (ΔE) is more than 10 (due to excess green), which is considered not a very good indicator even for a consumer device. However, at the same time, the variation in color temperature and ΔE is small, which has a positive effect on the visual perception of color balance. The dark areas of the gray scale can be ignored, since the color balance is not of great importance there, and the measurement error of 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 problems even on a sunny summer day. In complete darkness, the brightness can be lowered 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 - in visual assessment - color balance. Disadvantages - weak oleophobic coating, low black stability to gaze deflection from the perpendicular to the plane of the screen, fast drop in image brightness when viewed from 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 to say that it is bad.

Sound

The rear speaker in Nokia X2 seems to have been moved only a little, and that's where the innovations ended. Listening impressions remained about the same as in the first model. The sound quality is in line with expectations from budget smartphones. There is no distortion at maximum volume.

As for the conversational dynamics, some progress is noticeable here. Nokia X2 no longer sins with timbre distortion. But one should not dream of crystal clear communication, which is characteristic of flagships.

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

Telephone part and communications

Nokia X2 is equipped with two Micro-SIM slots, and one of them supports the "hot-swappable" function, which does not require rebooting the smartphone. Any of the cards can be assigned for data transfer, in this respect 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 the creation of a hotspot 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 contact them immediately.

USB OTG is not supported by the smartphone, but a 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 the average value.

Camera

The Nokia X2 has gone a long way in taking 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 grew to 5 megapixels and acquired a flash. In addition, there was a front camera with a resolution of 0.3 megapixels.

The work of the main camera was commented by Anton Solovyov:

	The sharpness of the plans is not bad.
	Noise reduction processes noise only in weak shadows. In the strong, they are noticeable, but not conspicuous.
	Despite some noise, the color of the sky is quite even.
	On the right you can see the blur zone.
	The number of the nearest car is distinguishable, but the more distant numbers are no longer possible to make out.
	Sharping on the wires is practically absent.
	The camera does a good job with macro photography.
	The text of the camera works well, but not all characters are well distinguishable.

For its 5 megapixels, the camera is not so bad, although it has a lot of problems. Noise cancellation tries to work as neatly as possible, and as a result makes almost no visible improvements. On the other hand, the sensor makes noise quite “softly”, and noises are not striking. The optics in the camera are quite good. In places, for some reason, blur zones appear, but in general, the pictures are quite sharp across the field and according to the 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 scenes. But shooting a 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 bitrate. Although if you remember that Nokia X shot at a maximum of 352 × 288, progress is obvious.

Software

Nokia X2 runs on Nokia X2 2.0 operating system (apparently based on Android 4.3). From the original OS installed in Nokia X, it differs only in appearance. The structure of the system remained unchanged. The main screen contains application shortcuts in the form of tiles, as in Windows. Left swipe opens a list of all applications, and right swipe opens the Fastlane notifications feed. The operating system is generally stable, 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. Play Store is missing. What's more, you won't even be able to add a Google account to import contacts and other information. It's easy to fix.

Pre-installing the driver and obtaining Root rights is easy to do through the utility. During installation, a prompt or two from the application will pop up on the phone - confirm them. Through Nokia X2 Tools, you can also install the Play Market. 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 out of it. After copying and changing permissions, restart your smartphone. Play market installed.

The new version of the Nokia X OS has become even a little closer to the original Android. Now, by shifting from the top, you can call up two separate menus, with notifications and switches. This expands the functionality somewhat, more icons are placed than before

The Achilles' heel of Nokia X was Internet surfing, namely 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 of 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. For graphics, the Adreno 302 chip is used. The configuration is very budgetary, you should not expect more from Nokia X2. Fortunately, the manufacturer has expanded the amount of RAM to one gigabyte, which can not 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.

	Nokia X2 (Qualcomm Snapdragon 200)	Nokia X (Qualcomm Snapdragon S4 Play)	Explay Atom (Mediatek MT6572)	Oppo Muse R821 (Mediatek MT6572)
3DMark Ice Storm (more is better)	4094	2338	1882	1905
3DMark Ice Storm Extreme (more is better)	2252	1296	812	939
3DMark Ice Storm Unlimited (more is better)	3710	2245	—	—
Nenamark 2	53.0 fps	32.3 fps	41.9 fps	—
Basemark X Middle Quality (more is better)	3682	—	—	—
Bonsai Benchmark	1634 (23.3 fps)	823 (11.7 fps)	—	—
Epic Citadel High Quality	42.9 fps	23.4 fps	—	—
Epic Citadel Ultra High Quality	32.3 fps	—	—	—

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

Through the efforts of Google Chrome, the Snapdragon 200 single-chip system defeats the similar Mediatek. Based on the hardware capabilities, Nokia X2 could aim at 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, not the heaviest Asphalt 8 will complain about the lack of memory. Fans of the X series still 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 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 "Methodology for testing video signal playback and display devices. Version 1 (for mobile devices)"). Screenshots with a shutter speed of 1 s helped to determine the nature of the output frames of video files with different parameters: resolution (1280 × 720 (720p) and 1920 × 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 fps) varied. from). In tests, we used a regular video player. The test results are summarized in the table:

Note: If both columns Uniformity And Passes green ratings are set, this means that, most likely, when watching movies, artifacts caused by uneven alternation and dropping frames will either not be visible at all, or their number and visibility will not affect viewing comfort. Red marks indicate possible problems with the playback of the respective files.

If we limit ourselves to 24-25 fps typical for cinema, then according to the criterion for displaying frames, the quality of playing video files on the screen of the smartphone itself is good, since frames (or groups of frames) can be displayed with 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 in the highlights, all gradations of shades are displayed in the case of ordinary video files.

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

Format	container, video, sound	MX Video Player	Regular video player
DVDRip	AVI, XviD 720×400 2200 Kbps, MP3+AC3	plays normally	plays normally, no subtitles
Web-DL SD	AVI, XviD 720×400 1400 Kbps, MP3+AC3	plays normally	plays normally, no subtitles
Web-DL HD	MKV, H.264 1280x720 3000Kbps, AC3	plays normally	played without sound
BDRip 720p	MKV, H.264 1280x720 4000Kbps, AC3	plays normally	played without sound
BDRip 1080p	MKV, H.264 1920x1080 8000Kbps, AC3	plays normally	played without sound

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

Battery life

The battery capacity of Nokia X2 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 over the entire discharge period, in the calculations it is worth adding about 6% of the time that the smartphone keeps at the last percentage.

	Battery capacity	Reading mode	Video mode	3D game mode
Nokia X2	1800 mAh	12 h 40 min	7 h 45 min	4 h 25 min
Nokia X	1500 mAh	14 h 15 min	6 hours 50 minutes	3 h 50 min
Explay Atom	2000 mAh	9 h 50 min	5 h 40 min	—
Oppo Muse R821	1700 mAh	20 h 30 min	10 h 30 min	—
Oppo Mirror R819	2000 mAh	10 h 20 min	8 h 20 min	5 h 00 min
Fly Luminor IQ453	2000 mAh	10 h 00 min	7 h 00 min	4 h 10 min
Alcatel OT Idol X	2000 mAh	10 h 00 min	6 h 40 min	4 h 00 min

Autonomy Nokia X2 has become more balanced compared to its predecessor. In reading mode, the smartphone holds less, but is still not inferior to most competitors. But a more powerful SoC consumes the charge more efficiently in more loaded modes, allowing you to increase battery life in games and when playing videos. Charging a smartphone from 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, functionality has been expanded, stability has improved, and some annoying problems have been fixed. Nokia X2 could easily compete on all fronts with more unprepossessing 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 the third version of Nokia X will increase the amount of flash memory to a viable 8 GB, and Windows mobile will leave something of them for modest user needs.
