Nokia Lumia won't turn on. What to do if Nokia Lumia does not turn on? All about nokia lumia

Any technology is subject to failures and operational errors. Smartphones running Windows 10 Mobile are no exception. If your Nokia, Microsoft Lumiya or other phone on the “ten” does not turn on or is frozen, then read this article to the end, perhaps you will find a suitable solution.

First of all, don't panic. And you don’t need to immediately run to the service center, where they will probably charge you quite a lot of money for fixing some minor error. Try the methods described below first and if they do not help, then you can think about going to a service center.

Regardless of whether your Lumiya is frozen or does not turn on at all, you can restart the phone by simultaneously pressing two buttons: Volume down keys and lock keys (on/off). Press and hold these buttons for 15-20 seconds. Before this procedure, connect the charger to the device!

If everything worked out, the smartphone display should go dark, and then vibrate briefly after 1-2 seconds. After this it will reboot.

Factory reset

Even if the phone is completely frozen, you can reset its settings to the factory state. How to do it? Press and hold simultaneously volume up and on/off keys. After this, an exclamation mark should appear. If this happens, then you need to do the following:

Click the add volume button;
Turn down the volume;
On/off button;
And turn the volume down again.

Flashing

You can fix the error due to which your Windows 10 smartphone freezes or does not turn on by flashing it. You can do this using the official utility from Microsoft, it’s called Windows Device Recovery Tool.

In fact, these methods are relevant for all Lumia smartphones (925, 920, 625, 520, 720, 640, 800, 1020, 510, 635, 630, 710, 730, etc.) and other phones running on Windows Phone and on Windows 10 Mobile.

The fate of the former leaders of the smartphone market - Nokia and Microsoft - remains the subject of numerous online battles and speculation. Despite various prophecies about the imminent death and futility of their modern mobile products (we are, of course, talking about Lumia smartphones and Windows Phone OS), both one and the other company continue to develop and demonstrate new developments. Of course, there is an opinion that Microsoft with its resources is capable of keeping even deeply unprofitable technologies and products afloat for a long time, but as a counter-argument it is worth noting that even the resources of such a huge corporation are not unlimited, and it can admit its mistakes, as was the case with devices Zune and Kin. Staying afloat, Windows Phone primarily supports Microsoft’s desire to create its own ecosystem in the likeness of Apple, with a “triad” smartphone-tablet-laptop (desktop computer), which, in addition to the obvious benefits from selling applications, music and other content, will attract and retain in its user boundaries. This example, again, was set by Apple when iPhone buyers then purchased iPads and eventually migrated from PCs to Mac OS X devices.

Nokia's benefit from using Windows Phone exclusively in its top-end devices is not so obvious. Almost immediately after the news of concluding a strategic partnership with Microsoft, the company began to hear statements about short-sightedness and requests or even demands to release devices on Android. It is difficult to say what exactly made Nokia refuse to join the community of Android smartphone manufacturers: perhaps close ties between the management of Nokia and Microsoft, perhaps some special conditions of the licensing agreement and access to OS development, perhaps the desire to “not be like everyone else” , and perhaps all together at once. How correct this strategy turned out to be can only be answered by time, but now the Finnish company’s position is very unstable: if Nokia took second place in the regular mobile phone market in 2012 in terms of the number of devices sold, then in the increasingly popular and more profitable smartphone segment the company continues lose positions after the release of devices with Symbian is discontinued. If you go by the Gartner report, the share of Windows Phone in the mobile OS market is increasing, but at a too slow pace to have a positive impact on the fate of such a “mono-system” manufacturer, which Nokia has become of its own free will.

Another mistake of Nokia, according to many fans of this company, was its focus on producing premium devices and smartphones in the mid-price segment. For a long time, almost two years, if you wanted to buy a Lumia device and get acquainted with the new Microsoft/Nokia platform, you had to part with a significant amount of money, purchasing a powerful device with excellent hardware, but limited in terms of software. It is clear that there were few people willing to experiment for a decent amount of money. Having finally realized that the Nokia Asha platform in the budget segment is not a replacement for Lumia smartphones, the Finnish company announced several mid-budget devices at once. One of them was the Nokia Lumia 520 smartphone, whose price—135 euros at the time of announcement—at the same time made it the cheapest smartphone in the entire Lumia line and spurred public attention. Finally, a worthy rival to numerous budget Android devices and a worthy candidate for a financially easy acquaintance with Windows Phone 8 was about to appear on the market.

In reality, when the communicator appeared on store shelves, its price, naturally, turned out to be not as attractive as in the announcement. However, the smartphone still remains the most affordable device in the Lumia family.

Contents of delivery

The Nokia Lumia 520 mobile computer comes in the company's traditional small box made of extremely thick cardboard. In addition to the image of the smartphone in various colors, the packaging provides only licensing information and data on the configuration. You won’t be able to find out anything about the characteristics of a smartphone by picking up its packaging in a store - apparently, the developers decided that if you paid attention to the Lumia device, then you already know the details about its filling or you don’t need this information.

In general, the Nokia Lumia 520 package is standard for a budget smartphone - nothing extra, just the essentials: charger, Micro-USB cable, wired stereo headset, battery and documentation.

Characteristics

Since the Nokia Lumia 520 is the cheapest smartphone in the Lumia line, the developers removed everything from it that, in their opinion, was unnecessary. In addition, they were faced with the task of separating the 520 and 620 models as noticeably as possible, the implementation of which, obviously, also negatively affected the characteristics of the hero of the review.

So, what features does the Nokia Lumia 520 have?

SoC Qualcomm Snapdragon S4 Plus MSM8227, 1.0 GHz, 2 Krait cores
GPU Adreno 305
Operating system Microsoft Windows Phone 8
Touch display 4″, IPS, 800×480, capacitive (high sensitivity), multi-touch
Random access memory (RAM) 512 MB
Internal memory 8 GB, microSDHC memory card slot
Communication 2G GSM 850, 900, 1800, 1900 MHz, 3G WCDMA 850, 900, 1900, 2100 MHz
Data transfer GPRS, EDGE, HSDPA, HSUPA (up to 21.1 Mbit/s)
Bluetooth 3.0, Wi-Fi 802.11b/g/n (2.4 GHz)
A-GPS, Glonass, gyroscope, orientation sensor, accelerometer, proximity sensor
Cameras: 5 MP (autofocus)
Battery 1430 mAh
Dimensions 119.9x64x9.9 mm
Weight 124 g

In terms of platform, the Lumia 520, 620 and 720 are almost identical. They are built on the same SoC Qualcomm MSM8227, which includes two Krait computing cores, the maximum operating frequency of which is 1 GHz, and a core for working with Adreno 305 graphics. You can find out more about Qualcomm processors in general and about this single-chip system in particular from our special material.

The amount of RAM in these smartphones is also the same - 512 MB, modest by today's standards. Modest, of course, if you compare head-on devices based on different operating systems, which is fundamentally wrong. Apparently, the Windows Phone 8 OS itself and its applications consume less memory than Android and its programs, because according to independent utilities, the Nokia Lumia 520 has 395 MB of RAM available.

There are also no differences in the amount of built-in flash memory for the Lumia 520, 620 and 720. All smartphones have exactly 8 GB of it; in the case of the Nokia Lumia 520, 5.2 GB are available to the user, a significant part of which will be occupied by built-in applications. Expand your storage space for music, photos and videos with removable microSDXC memory cards up to 64GB. The smartphone owner is also provided with 7 GB of data in the Microsoft SkyDrive cloud service.

Actually, the similarities between the 520 Lumia and its older sisters end with the hardware; in other key parameters, the Lumia 520 is significantly inferior to them.

The Lumia 520 has an IPS matrix with a resolution of 800x480 pixels, like most Lumias, but the display itself does not have a polarizing filter, it does not support ClearBlack technology, there is no Gorilla Glass protection glass and there is no oleophobic coating. Thank you for supporting screen touch recognition while wearing gloves.

The developers of the Lumia 520 left only one camera, depriving it of any flash. In terms of basic photo and video capabilities, it is practically not inferior to cameras of more expensive smartphones.

The battery of the review hero does not have a large capacity and size; the amount of stored energy is 1430 mAh. But, unlike the batteries of other Nokia mobile devices, it is removable.

Design and appearance

In my subjective opinion, the Nokia Lumia 520 is a very nice smartphone. Perhaps it’s my personal preferences for the angular-rectangular design or the optimal, again in my opinion, proportions and dimensions of the device and the cute multi-colored back covers made of soft-touch plastic (you can purchase several colors). The 520th model looks more advantageous even than the “washed up” 620th. All these are personal impressions, now let's move on to the facts.

Neither in size, nor in thickness, nor in weight, Nokia Lumia 520 does not fall into the category of ultra-thin and ultra-light communicators. However, you don’t expect this from a budget device. On the other hand, the communicator is comfortable to hold and operate with one hand - the thumb easily covers the area of the screen, which is small by today’s standards, and the thick rounded “rubberized” edges of the boat-shaped back cover provide a reliable grip. In general, the design of the body of the review hero is one of the most optimal in terms of the reliability of the smartphone’s position in the hand and its control; only the sharp corners sometimes dig into the palm if you take it incorrectly.

There are no serious complaints about the design and build quality of the Nokia Lumia 520. The smartphone itself fits securely into the cover shell; the creaking is observed only if you press hard on its center; There are no backlashes or large gaps between parts. There are also several minor design flaws: dust collects in the hole for the telephone speaker, the hardware buttons are a little loose in the grooves, the touch keys are not backlit and are often triggered by false touches when working with the smartphone carelessly.

On the front panel of the smartphone, in addition to the display, touch keys and speaker, there is a microphone, light and proximity sensors.

It is difficult to remove the communicator body from the cover without long fingernails: you have to contrive and press on the camera lens to move the body. If you pick up its edge in the area of the telephone speaker with your fingernail, then detaching the cover is quick and painless. Reinstalling the smartphone case into the shell cover does not cause any particular problems.

Only by removing the battery cover can you access the battery, as well as Micro-SIM and microSD cards. You cannot replace them without turning off the power to the device and disconnecting the battery. It's funny, but on the back of the cover there is a rectangular piece of rubber glued to it, which should ensure the strength of the smartphone's structure and prevent the back panel from sagging. Judging by the presence of the mentioned small squeaks, it copes with its task only with a C grade. The role of the second stop for the cover is played by the rubber frame around the main speaker of the smartphone.

There are technological holes in the battery compartment cover for all connectors, the main speaker and the camera lens. Hardware keys are presented in the form of plastic repeaters attached to it. There is no protection for the camera lens, but it itself is slightly recessed relative to the level of the back panel - so, unlike many other smartphones, the Nokia Lumia 520 does not rest on it when lying “on its back”.

The left side of the Nokia Lumia 520 is empty, on the right there are three hardware keys: double for volume control, power and camera controls. They all have a raised, comfortable shape and a clear press, but the last parameter is greatly influenced by the correct installation of the cover: with a slight displacement and distortion, the buttons stop being pressed clearly.

At the top end of the body of the review hero there is a 3.5 mm headphone jack. On the bottom there is a Micro-USB connector.

Overall, the appearance and design of the Nokia Lumia 520 is not bad. Of course, they cannot be compared with the outstanding technological solutions made of glass and aluminum from devices in the highest price range, but for a budget smartphone, the hero of the review looks and is put together quite well.

Software

The Nokia Lumia 520 smartphone runs the Windows Phone 8 operating system. Since Microsoft still prohibits any interference with the appearance of the system, all the few devices running this OS have a standard graphical interface. Changes made by the manufacturer of a specific smartphone model are limited to adding third-party software and disabling certain hardware-related functions and settings.

In addition to the famous manufacturer, Nokia devices are also attractive due to the abundance of proprietary software developed by this company. We are primarily talking about navigation services, united under the general name Here: Drive, Maps and Transit. Here Maps allows you to view maps in online and offline modes, search for a specific address and organization, get directions - in general, everything that Google Maps and Yandex.Maps can do. Here Transit, as the name implies, allows you to plot your travel route on public transport. Here Drive is a convenient car navigator. These programs, naturally, have their advantages and disadvantages: the first is the ability to download maps of almost all countries on Earth for free, the second is a slightly confusing interface. Previously, they also lacked support for a traffic monitoring service, but in the latest versions of the applications, traffic jams have appeared. It should also be noted that free maps of any region can be used only in Here Maps and Here Transit, and in Here Drive there is a restriction on maps only of the region where the SIM card inserted into the smartphone is from. The full version of the program, Here Drive+, does not have such a limitation; the update costs 664 rubles.

Music Nokia+ is a multimedia combine of free streaming radio (with the ability to offline listen to your favorite tracks for a monthly subscription) and a regular digital music store. The approach, in general, is clear; more and more such applications and services are now appearing, but the Nokia application combines two approaches at once: one from iTunes, the other from Yandex.Music.

Nokia Care— a program-collection of tips on using the capabilities of a smartphone and its maintenance. Nokia Live Photos- a kind of application for “revitalizing” photos and showing them to friends on social networks. Nokia Panorama allows you to create panoramic images using the camera built into your smartphone.

Nokia Ringtones Maker can create and set any non-DRM protected music track from the device memory as a ringtone. Nokia Top Applications it simply provides a list of programs from the Windows Phone Store that are interesting, from the point of view of service developers. Nokia Smart Photo helps you choose the most successful frame from a series of pictures that the program itself takes.

This completes the list of additional Nokia software. In the smartphone settings there are several more tabs dedicated to accounts in the company’s services, pairing with branded accessories and contacting support with reviews, but it doesn’t make much sense to dwell on all of them. It also makes no sense to pay attention to the MTS programs and services that are installed in the memory of this particular Nokia Lumia 520. The smartphone was purchased in the store of this operator, since it was originally sold only there, and most of the mentioned functions are tied to the SIM card of this company.

Display and sound

The screen is exactly what the developers of the Nokia Lumia 520 seriously saved on. On paper, everything looks great: IPS matrix, 4-inch diagonal, resolution 800×480 pixels, density 233 pixels per inch, 16 million colors. But in practice, the display of the review hero is mediocre, nothing more.

The black color on the Nokia Lumia 520 screen looks gray, all owners of the smartphone noticed this, and nothing can be done about it. The display of the review hero is not able to show true black color. The lack of polarizing and anti-glare filters, as well as ClearBlack technology, also has a negative effect when working with a smartphone in bright external lighting conditions - it becomes difficult to see anything on the Nokia Lumia 520 screen. It’s good at least that there is practically no color inversion observed.

The touch sensor recognizes up to five simultaneous signals, but the quality of its operation is not very good - after the third touch it begins to get confused.

The protective glass of the display, not Gorilla Glass, gets very dirty when working with a smartphone, due to the lack of an oleophobic coating. If you don't wipe it, fingerprints quickly cover the entire screen.

The operating system controls the brightness of the display backlight based on the readings of the ambient light sensor. The backlight power level can also be indirectly set manually; there are three brightness settings in total.

A detailed examination of the screen using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections, Alexey Kudryavtsev.

The smartphone screen is covered with a glass plate with a mirror-smooth surface and, judging by the reflection of objects in it, it does not have an anti-glare filter (or it is very weak). The reflection in the screen triples, which suggests the presence of an air gap between the surface of the matrix and the outer glass. On the outer surface of the screen, apparently, there is still a special oleophobic (grease-repellent) coating, but in this case it is not very effective - the finger glides over the surface of the screen poorly. And yet, fingerprints are easier to remove from such a screen, and appear on it at a lower speed than in the case of ordinary glass.

With manual brightness control (three fixed levels available) and when the white field was displayed on the entire screen, the maximum brightness value was about 310 cd/m², the average was 200, and the minimum was 80. These three levels are more or less suitable for comfortable daytime work on the street, in a well-lit room and in the dark. Although, of course, the maximum brightness value is not very high. Note that in the screen settings there is a checkbox that turns on a special mode for increasing readability in the sun, but we did not find any visible or detectable effect from turning on this mode (neither in the dark, nor in a lit room, nor in the sun) - exactly the same , as in the case of previous Nokia smartphones with the same option. Either the company introduced this option so that the user is aware of the supposedly improved readability in the sun and can even “turn it on,” or the effect is so minor that there is no real improvement (or there is always one).

There is automatic brightness adjustment based on the light sensor (it is located to the right of the logo on the front panel). In automatic mode, as external lighting conditions change, the screen brightness both increases and decreases. You can make adjustments to the operation of this function by first selecting the brightness level. Next, we present the screen brightness values (when the white field is displayed in full screen) for three values of the selected brightness (for levels short, average And high). In complete darkness, in automatic mode, the brightness is reduced to 10, 12 and 15 cd/m², respectively (a little dim, but you can read), in an office illuminated by artificial light, it is set to 125, 160 and 190 cd/m² (acceptable), in a brightly lit environment (corresponding to daytime outdoor lighting, but without direct sunlight) increases to 270, 380 and 380 cd/m² (the last two values are even higher than with the manual high brightness setting). As a result, this function works more or less adequately. Brightness adjustment is carried out using pulse width modulation (rectangular pulses with 100% amplitude) with a frequency of 326 Hz. This is a fairly high frequency, so when working with a smartphone, the flickering of the backlight at low brightness is not visible, but if desired, this flickering can be detected, for example, by quickly waving a pencil in front of the white field on the screen.

This screen has an IPS type matrix. The micrograph shows a typical IPS subpixel structure:

The screen has very good viewing angles without inverting shades and without significant color shifts, even with large viewing deviations from perpendicular to the screen. True, it seemed to us that the brightness of the white field decreases more when deviated, and the shift in the shade of gray colors is greater than in the case of a typical screen of a modern smartphone with an IPS matrix. When deviated diagonally, the black field becomes very bright and acquires a purple tint. When viewed perpendicularly, the uniformity of the black field is good. The response time for the black-white-black transition is 30 ms (17 ms on + 13 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 42 ms. The contrast ratio is typical for IPS - 666:1. The gamma curve constructed using 32 points did not reveal a blockage either in the highlights or in the shadows, and the index of the approximating power function is 2.38, which is slightly higher than the standard value of 2.2, while the real gamma curve deviates little from the power dependence:

There may be dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image. This is confirmed by the fact that the ratio of the brightness of the white field to the brightness of the black field is 800:1, which is greater than the contrast value given above. As a result, the resulting dependence of brightness on hue (gamma curve) may not correspond to the gamma curve of a static image, since the measurements were carried out with sequential display of shades of gray on the entire screen.

The color gamut is slightly narrower than sRGB. However, important reference points - green color and skin tones (between the green and red vertices of the coverage triangle) - are close to the boundaries of sRGB, so in general, images on the screen have a saturation close to natural.

Apparently, the matrix’s light filters mix the components with each other. The spectra confirm this:

This technique allows you to increase the brightness of the screen with the same energy consumption for backlighting. The balance of shades on the gray scale is good, since the color temperature is not much higher than the standard 6500 K, and the deviation from the blackbody spectrum (delta E) is less than 10, which is considered an acceptable indicator for a consumer device. At the same time, the variation in color temperature and delta E is small, which also 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.)

The color balance and automatic adjustment of screen brightness do not cause any complaints - unlike other screen characteristics, which are typical for a budget solution, that is, not outstanding. Well, at least the IPS matrix.

The main speaker of the Nokia Lumia 520 has high volume and good sound quality, but it is very easy to muffle it by covering the corresponding hole on the back of the smartphone with your finger. The telephone speaker also left a positive impression: the volume and clarity of the sound allow you to successfully communicate with your interlocutor even in a relatively noisy place. There were no complaints on the other side of the telephone line, which means that the microphone on the Nokia Lumia 520 also copes with its duties well.

Nokia Lumia 520 has a very powerful and high-quality headphone output. Paired with good headphones, the hero of this review can provide comfortable listening to music in almost any conditions; you just need to remember its negative effect on hearing if you try to compete with the external noise in the subway. The complete headset deserves only a satisfactory rating. Unprepossessing in appearance, with only a microphone and no answer key, it provides acceptable sound quality. There are no creaks, rattles or hisses throughout the entire power range, but the sound itself looks too flat: high frequencies are difficult to hear, and low frequencies merge into a hum.

It's a shame that the Nokia Lumia 520 doesn't have a built-in FM radio.

Wireless Interfaces and Communications

Despite its budget, Nokia Lumia 520 has all the most popular modern communication tools. It includes: 2G and 3G cellular communications with HSPA+ support, Wi-Fi IEEE 802.11b/g/n, Bluetooth 3.0 and a combined A-GPS/GLONASS receiver. What distinguishes the review hero from older models is the lack of support for LTE and NFC.

There were no problems with the operation of the cellular communication module. The smartphone quickly connected to the network and provided reliable communication in various conditions. Data transmission over the mobile network was mainly limited by its capabilities, rather than by the capabilities of the device. Testing the connection speed in the field conditions of the Moscow region showed good results. It’s funny, but sometimes instead of the “H” icon, the smartphone showed an unusual “4G” icon - it is clear that there is no LTE in the Nokia Lumia 520, and outside of Moscow it is found only sporadically. Apparently, the operating system simply perceived the HSPA+ signal that way.

Connecting to a home 802.11n network with a TP-Link TL-WR1043N router as a base station also went without incident. The speed of the connection to the network in this case was limited only by the capacity of the communication channel with the provider. According to subjective impressions, the Wi-Fi signal reception quality of the Nokia Lumia 520 is better than that of many other communicators. Thus, the hero of the review successfully detected the network and connected to it where the Samsung Galaxy S2 did not find anything.

The Bluetooth file transfer speed between MacBook Pro 2009 and Nokia Lumia 520 was 1.6 Mbps. Unfortunately, the hero of the review does not have a Bluetooth modem profile, so you can distribute mobile traffic only by organizing a Wi-Fi access point. Pairing the smartphone with the Sony MW1 wireless headset initially caused both devices to freeze. After the reboot, their connection was restored and it became possible to use the headset both for listening to music and for phone calls. The functionality of the headset, however, remained at a basic level: the names of the tracks on its screen were displayed normally, but instead of names from the smartphone’s address book, only numbers were displayed.

The operation of the A-GPS/Glonass receiver did not cause any complaints. Both built-in navigation applications and third-party ones quickly determined the location of the device, and the connection was stable in the future.

Camera

Nokia Lumia 520 has a single camera with a resolution of 5 megapixels. It is equipped with an autofocus system, but does not have a flash.

It is most convenient to control shooting using a separate hardware key located on the right side of the smartphone body. The interface of the camera control program is very laconic; on the main screen there are only icons for shooting modes and calling up settings. The list of settings itself is very short, it contains only the basic basic parameters.

The camera and control program start up quite quickly, but the process of taking a picture is somewhat slow due to the thoughtfulness of the autofocus system. But once you specify the focus area by touching the screen, you don’t need to worry about “releasing the shutter”: the camera itself will try to focus and immediately take the picture.

The maximum image resolution of the Nokia Lumia 520 camera is 2592×1936 pixels. Video shooting is carried out with a resolution of 720p and a frequency of 30 frames per second, the recording format is MPEG-4, AVC/LC-AAC. The quality of photos and videos, in subjective opinion, is not bad for a budget smartphone.

Battery life

It is difficult to expect outstanding battery life from a device whose battery capacity is only 1430 mAh. However, the Nokia Lumia 520 hardware is not exactly the most powerful, and the smartphone developers clearly tried to squeeze extra minutes of work out of their hardware and software platform - which is worth a separate tab in the device settings, responsible for enabling and configuring the energy saving mode. To make the results more fair and objective, this mode was disabled in all our traditional tests, since it could not seriously affect music playback, and reducing the backlight brightness in the e-book reading test contradicts our methodology for measuring battery life. So, without beating around the bush, here are the test results.

When playing music, the smartphone screen was turned off, when reading, the brightness was set to 100 cd/m², and a 720p video in MP4 format (H.264/AAC) was used. As you can see, the results were by no means the worst. They almost completely coincided with the performance of the Nokia Lumia 720, which is built on the same platform as the hero of the review, and this despite the latter’s smaller battery capacity. Surely the small diagonal of the display had a positive effect.

In general, the Windows Phone 8 platform and the Qualcomm MSM8227 SoC showed good results in battery life tests. In terms of activity time away from power sources, the Nokia Lumia 520 is on par with devices such as “long-lasting” Android smartphones based on the MediaTek platform, and provides its owner with an acceptable level of mobility.

The battery of the review hero charges very quickly, in just over a couple of hours - thanks to the included charger with a charging current of 0.75 A.

Performance

This is perhaps the most uninteresting part of any Windows Phone 8 smartphone review to date. It is uninteresting for several reasons. The first is the small number of devices with this OS on board and the extreme similarity of their hardware characteristics: in fact, all current Windows backgrounds are built on the basis of several SoCs and differ only in display resolution. The second reason is the pointlessness of comparing devices with different operating systems, since more or less relevant results can only be given by cross-platform browser tests, which depend only on the “raw” processor performance and optimization of the JavaScript engine in a specific mobile browser. Truly relevant and convenient benchmark programs for comparing devices on different OS have not yet been created.

Be that as it may, we will rely on the existing tools. Since the Nokia Lumia 520, 620 and 720 are practically twins in terms of hardware, there are no serious differences in the results of their tests. It is unlikely that Nokia engineers could have consciously or unconsciously deteriorated the platform of the review hero, and without such errors there would be nothing to have any impact on the final scores.

However, as it turned out, in most tests the Nokia Lumia 520 even outperformed its older brother, the Nokia Lumia 720. It is difficult to say what the reason for the priority of a more budget smartphone on the same hardware platform may be - perhaps in the case of the AnTuTu test it is that that the Nokia Lumia 720 has not been tested for graphics processing speed.

Here the assessments of Nokia Lumia 520 and 720 practically coincided, which once again proves the direct dependence of these tests on processor performance.20565

The hardware performance of the Nokia Lumia 520 smartphone is quite enough for games. Angry Birds, Asphalt 7, Assasin’s Creed, NFS: Hot Pursuit - they all launched and worked normally after being installed in the memory of the review hero. Despite rumors about limited support for some games for devices with 512 MB of RAM, we did not encounter them during testing.

In general, the performance of the Nokia Lumia 520 is not at all budget - by the standards of devices with Windows Phone 8, of course. Everything that a mid-price segment smartphone such as the Nokia Lumia 720 can offer is in the current hero of the review.

Playing video

The video player built into the OS in the Nokia Lumia 520, as in the case of the Nokia Lumia 720, refused to play videos contained in media containers that were incomprehensible to it. He knows the codecs themselves: after all, if you save the video in MP4 format, the reviewer will play the movie in H.264/AAC format with a resolution of up to 1080p without any problems.

We did not find an MHL interface 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, using a set of test files with an arrow and a rectangle moving one division per frame (see Methodology for testing video playback and display devices. Version 1), we checked how the video is displayed on the screen of the smartphone itself. 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 tests we used the standard video player. The test results are summarized in the table:

File	Uniformity	Passes
Screen
watch-1920x1080-60p.mp4	not playable
watch-1920x1080-50p.mp4	not playable
watch-1920x1080-30p.mp4	Great	No
watch-1920x1080-25p.mp4	Great	No
watch-1920x1080-24p.mp4	Great	No
watch-1280x720-60p.mp4	not playable
watch-1280x720-50p.mp4	Fine	No
watch-1280x720-30p.mp4	Fine	No
watch-1280x720-25p.mp4	Fine	No
watch-1280x720-24p.mp4	Fine	No

Note: If both the Uniformity and Dropout columns are rated green, this means that when watching movies, there will most likely be no or no amount of artifacts caused by frame spacing or dropouts visible. will not affect viewing comfort. “Red” marks indicate possible problems associated with the playback of the corresponding files.

The intervals between frames (or groups of frames) alternate more or less evenly, but files with 50 fps (720p and 1080p) and 60 fps (1080p) are not played back. The smartphone cheerfully starts playing a 720p file at 60 fps, and does it well, but only for the first few seconds, and then the playback turns into a slideshow. Strange but true: in general, 1080p files play back slightly better than 720p. The displayed brightness range exactly corresponds to the standard video range - all shade gradations are displayed in shadows and highlights (for video in the range 16-235).

Impressions and conclusions

Since the Nokia Lumia 520 is the cheapest smartphone with Windows Phone 8, we had to make allowances for this throughout the review: this function is missing, it was worsened here, something was excluded there - but for that kind of money... Yes, the low price of the smartphone makes it comparable to other Windows Phone 8 devices is very simple. The main conclusion is this: if you want to get acquainted with the modern Microsoft mobile operating system and its ecosystem, your choice is the Nokia Lumia 520. In my opinion, in this case there is no need to overpay for more expensive models.

If you just need a good smartphone running Windows Phone 8, then you should also opt for the Nokia Lumia 520, since in terms of its basic capabilities, hardware, performance and battery life, it is in no way inferior to the 620 and 720 models, and the Lumia 820 and 920 costs completely different money. In fact, the hero of the review has only two serious drawbacks: a mediocre display, as well as a missing front camera and LED flash.

The hero of the review also looks worthy in comparison with the general mass of budget smartphones, including the legion of Chinese devices. Firstly, it can already be purchased at almost the price originally announced by Nokia - a little less than $200, which puts it on the same level as the Chinese on Android. Secondly, the hardware of the Nokia Lumia 520 is practically the best that the segment of Windows Phone smartphones can provide for the most modest money. Of course, Chinese devices with Full HD displays and quad-core processors will look more interesting on paper and in the hand, but only until something starts to freeze, crash or fall off. Nokia still provides some quality workmanship, and Windows Phone 8 itself is very undemanding in terms of resources, works smoothly and quickly.

As for the Microsoft mobile platform, it only has two serious shortcomings; fatal or not - only time will tell. The first of them is still a significant lag behind Apple and Google in filling their own application store. The situation with ordinary popular programs is slowly improving; from my own minimum of necessary software, I could not find only a normal offline dictionary, such as Lingvo, and a navigation program with support for a traffic jam tracking service, such as Yandex.Navigator. Moreover, Lingvo is available in the Windows Phone Store, and it costs the same money as for iOS, but to search the dictionary it requires a network connection, and if you have access to the Internet and a browser, then why a separate and paid program? To create Yandex.Navigator, its developers need some access to low-level programming interfaces, which Microsoft refuses to provide. Why they need it is unclear; regular Yandex.Maps and Here Drive work just like that. Thus, the main problems of the current Windows Phone Store are the absence of several programs that are truly necessary in everyday life, whose developers are in no hurry to do anything for their appearance, and an extremely meager, almost poor selection of entertainment applications and especially games. While iOS continues to port classic games and create great new ones, Windows Phone 8 is left content with a few popular games from other platforms (the appearance of Angry Birds was a real event), games owned by Microsoft companies and a very diverse, but equally uninteresting arcade and puzzles from independent developers. A sad and strange situation, considering Windows Phone's support for the popular DirectX.

The second serious drawback is the continued division of memory into internal, which is suitable for installing programs, and external (for example, on a microSD card), on which you can only save music, photos and videos. Of course, 8 GB of internal memory is a lot by the standards of Android, but by the standards of Windows Phone 8 it is very little: it gets filled with applications and their data very quickly, and as a result you get a comical situation when the internal memory has run out, and the memory card Tens of gigabytes are free.

Despite the improvement in the interface and capabilities of the operating system, it still has many minor flaws and errors - I will list just a few. Disconnecting the battery resets the date, time, and volume settings. The voicemail phone number specified in MTS cannot be changed (more precisely, it is possible, but to no avail). When launched, the phone control program displays a list of recent calls instead of the telephone keypad, and to see it, you need to touch a very small icon with your finger. The Yandex search built into the system works poorly: it either refuses to update the search results list, or does not update its own widgets, instead of redirecting to the site, it produces a list right in the same window, and, most importantly, it does not search for anything in the memory of the smartphone itself - not contacts, no programs, no files. Why does such a search need a separate key on the device body?

Many things that you get used to when using other smartphones are not present at all in Windows Phone 8. There are no convenient indicators of the operation of wireless communication modules, there is no way to quickly enable or disable them without digging into the settings (the Battery program provides significant help here). The same “dialer” program cannot search for entries in the contact list either by the first digits of the number or by the alphanumeric representation (3 for DEF, 4 for GHI, and so on). The list of such small but unpleasant things can be continued endlessly; Perhaps I’ll focus on these few, which especially interfered with long-term work with a smartphone.

Now on to the good stuff: The clunky Zune has been replaced as the only desktop sync program by simply “Windows Phone for Desktops” in PC and Mac variants. The functionality implemented in the program is quite good, for example, it can synchronize the contents of the smartphone’s memory with iTunes - something that owners of Android devices will apparently never see out of the box. There is also a second connection option - as an MTP device with direct access to the microSD card and some directories of the smartphone’s main memory.

In general, Windows Phone has room to develop; the system has already come a long way from the deplorable state of the original Windows Phone 7, and there is no point in stopping at half of it. The platform has potential, no one will deny this. With the release of Nokia Lumia 520, assessing all the features and disadvantages of Windows Phone 8 has become much easier and cheaper.

All smartphones in the Lumia line, and especially the latest models, have proven themselves to be phones that, in very rare cases, experience software or hardware failures. But still, it’s just hardware, and like any other smartphones, they sometimes don’t see the connected charger or don’t want to start. The reason for all this is a software error or simply a “bug” that prevents your device from working smoothly. For the entire Nokia Lumia line with Windows Phone 8, this problem can be solved as follows:

— connect the phone to the power supply;

— simultaneously press the phone power and volume down buttons for about 15-20 seconds;

The idea is that after these simple manipulations the phone should come to life. But if nothing has changed, try doing the same procedure, just before doing this, connect your gadget to power for 20-30 minutes. As phone owners who go through this write, the first option mainly helps, without using a charger.

I know another option - this is a hard reset. How to make it? It’s very simple, press three buttons together: volume down, camera button and phone power button. But I dare to tell you that after applying a hard reset, all personal content (contacts, photos, video files, applications and games) will be deleted on your smartphone.

And after watching this video, you will be even more aware of what to do if your Nokia Lumia does not turn on:

If these three methods do not bring the desired result, then go straight to the Nokia service center, they will definitely help you.

Nokia Lumia smartphones have proven themselves to be devices that rarely experience hardware or software failures. However, sometimes situations arise where they won't turn on or charge. As a rule, this happens due to an error in the software; in other words, a system glitch occurs that prevents the phone from turning on. You can solve this problem as follows:

If not Nokia Lumia 520,620,720,820,920 turn on and other smartphones running Windows Phone 8:

- connect the phone to the charger

- Press the power button and volume down button simultaneously and hold for 15 seconds.

As a rule, these simple actions are enough to “revive” the device. If this doesn't help, you should try keeping your phone on charge for at least 20 minutes and try again.

You can also try to do a hard (hard) reset of your phone, for which you need to simultaneously hold down the power button, volume down button and camera button. However, it is worth considering that a hard reset will delete all applications, games, photos and files. You can read more about soft and hard reset in.

In case of failure, it is best to contact the service, since trying to restore the phone yourself by flashing it via a PC can completely “kill” it.

For Nokia Lumia 610,710,800 and 900, the procedure is similar to smartphones running Windows Background 8.

The Windows Phone mobile operating system is now very actively developing, and it’s hard to argue with that. I also have a Windows Phone (Nokia Lumia 925), and I am very pleased with it. To be honest, I'm tired of Android, I want something new. But this article is not about my Lumia, and not about which OS is better. Phones running this operating system work stably, and in terms of accessing the Internet via Wi-Fi, everything is just as good.

For example, over several months I have not noticed a single problem in which Nokia Lumia would not want to connect to Wi-Fi, or the Internet would not work.

But, as I noticed, various questions appear about the problems that still arise when trying to connect a Windows Phone to Wi-Fi, or after connecting. Typically, these are problems when a connection to a wireless network is established, but sites on the phone do not open. Or, for example, when Nokia Lumia does not see the Wi-Fi network. Moreover, he does not see only one, the desired network, but he sees the neighboring ones.

In this article, we will try to figure out why problems may arise with connecting a Windows Phone to wireless networks, and how to solve these problems. At the moment, version WP 8 (I will show this version as an example), an update to Windows Phone 8.1 will be released soon. Perhaps there will be some changes in working with wireless networks.

Windows Phone connects to Wi-Fi, but the Internet does not work

This is probably the most popular problem. And as a rule, it is not the smartphone that is to blame for this problem, but the access point (router) itself. You connect the phone to the network, I wrote how to do this in the article, it connects (status: connection established), but when I try to open the site in the browser, an error appears: “The page cannot be displayed”. Applications such as VKontakte, Twitter, Skype cannot access the Internet.

When a smartphone cannot obtain an IP address

Typically, routers themselves distribute IP addresses and have a DHCP server enabled. But it happens that DHCP is disabled for some reason (when, for example, IP is registered manually on devices). Honestly, I haven’t found how to manually register an IP address on Windows Phone 8. I think that in Windows Phone 8.1 this problem will be fixed.

If your phone is unable to obtain an IP, you will most likely see an error something like: “The phone cannot connect to the Wi-Fi network because the network is not responding. Please try again later". Or, next to the name of the network, there will simply be an inscription “protected”.

You need to check if the DHCP server is enabled in the router settings. If not, then turn it on. I wrote how to do this in a separate article. See after the heading “Checking whether the DHCP server is enabled on the Wi-Fi router.”

You can also try the one on which your wireless network works. Try, for example, just n, or g.

Nokia Lumia does not see Wi-Fi network

When I write Nokia Lumia, I mean any phone on Windows Phone 🙂, well, you understand.

I highlighted a problem on some forum that Lumia (I don’t remember exactly which model), I didn’t see my home wireless network. It simply wasn't on the list of networks available for connection. The problem is not uncommon and can occur on any device.

So, in the case of an operating system from Microsoft, I would also recommend changing the channel on which the router broadcasts your wireless network. How to do this is written in detail. Since it is interference on the channel that usually causes such problems. Try some static channel rather than Auto mode. And don't put the channel higher than 12th.

Afterword

It seems like I wrote about all the popular problems. If you have encountered any other problem with the Internet via Wi-Fi on Windows Phone, or know some new solutions to the problems described above, you can share useful information in the comments. Don't be lazy :)
