System settings nokia lumia 520
Hello dear readers of our web resource site. Today I would like to touch upon one burning topic and give step by step guide about what needs to be done so that you can still have Internet on your Nokia Lumia 520.
Owl conducted her own investigation to find out all the details of the case. The connection experiment was carried out using the example of the mobile operator MTS.
So, after connecting to the tariff selected on the mobile operator’s website, you need to make settings in your Nokia device.
Step-by-step instructions for connecting to Nokia Lumia 520 Internet
METHOD 1
IN nokia lumia 520, setting up the Internet does not seem difficult, since it is a very reliable and smart smartphone. All you need to do is call special number 0876 for MTS (can be checked with technical support).
You dial the number and after a short recording of the answering machine, all settings are sent. The resulting settings are saved in a special service on your phone and automatically take effect.
Reboot your Nokia 520 and you are happy - the connection to the Internet is established.
METHOD 2
If for some reason you were unable to connect automatically, you can do it manually, which is not particularly difficult.
Move the desktop to the left and you will be taken to the list of all services, where you need to find the gear icon and select: Settings/access point. My default mobile operator is MTS – RUS Moscow. I leave everything unchanged and click on the plus icon at the bottom of the screen.
In the settings window that opens, I need to enter 4 parameters, which I first receive from MTS support:
- Connection name;
- Access point name;
- Username;
- Password.
In the 1st paragraph you need to indicate the name of the connection, which can be MTS Internet or mts - I chose the first.
In the 2nd paragraph the parameter is indicated: internet.mts.ru
In the 3-4th paragraph, indicate the login and password provided by the technical support service of the Internet cellular operator.
You leave parameters such as proxy (5-6th point) unchanged.
If you did everything correctly, the checkmark icon at the bottom of the screen becomes active. All you have to do is click on it and confirm the changes for them to take effect, and then reboot your Nokia 520.
What to do if you couldn’t connect to the Internet on your Nokia Lumia 520?
If you are just starting to get acquainted with the smart smartphone 520 model and do not know what could cause the lack of connection, then you need to pay attention to the following parameters:
Settings/Access Point
If you have made several connection attempts and the result is unsuccessful, then you need to do the following:
In the Settings/Access Point window, you will go down to the very bottom of the screen, where you can see all your created accounts with connection settings.
Select from this list those settings that you entered correctly or edit any account indicating correct settings. Next, make it active and reboot your smartphone.
Check the settings in the following directory: Settings/data transfer
The first field data transfer should be in the enabled mode, in the bottom field the fastest connection should be the 3G parameter.
Disable Wi-Fi connection if you were using it before connecting mobile internet. The Wi-Fi connection has its priority and becomes active when the browser starts. You can read about this in detail in the smartphone instructions.

*#7780# - restore original (working) smart settings
*#7370# - reset the smart to factory settings (i.e. all software, contacts, calendar, etc. are deleted - the smart becomes clean!)
ATTENTION! To use the last two codes you will need to enter the phone lock code (default 12345)!

*#7370925538# - clearing the “Wallet” (for 6600 and higher - which have a “Wallet”).
*3370# (phone must reboot) improves sound quality (using EFR), but reduces battery life.
#3370# - resets the sound quality to normal (cancels the *3370# code).
EFR CODEC (Enhanced Full Rate)
This function when enabled, in theory, it should significantly improve the quality of transmitted speech, but, unfortunately, it must be supported by the operator cellular communication. When it works, the phone's power consumption during talk time increases slightly (about 5%). As far as we know, none of the Russian mobile operators support this function. The principle is based on a different speech compression algorithm (ACELP) and occupies a wider frequency band.
*4720# - enable Half Rate Codec (HFR)
#4720# - disable Half Rate Codec (HFR)
HR CODEC (Half Rate)
Significantly degrades speech quality, but saves battery by about 30%. Again, must be supported mobile operator.

Codes for determining whether LOC is installed on the device or not
Your Nokia can be blocked by 4 types of locks:
SPROVIDER-LOCK - 1
NETWORK-LOCK - 2
COUNTRY-LOCK - 3
SIMCARD-LOCK - 4
To check the status of these locks, enter the following line:
#pw+(MASTERCODE)+(y)#, where
- p = press * 3 times
- w = press * 4 times (in the original, on the contrary, w - 3 times, p - 4)
- + = press * 2 times
- MASTERCODE = exactly the thing that was used to lock your device. But to check the status, enter 1234567890
- y = number from 1 to 4
If your phone is locked by an SP (Service Provider) code that is unknown, then try the following:
1. Request must be enabled Pin code;
2. turn on the phone;
3. When asked for a Pin code, press C, then the up or down arrow;
4. press C and hold until the display clears;
5. Now enter the command to change the Pin code, but without changing it;
**04*Pin*Pin*Pin#
This operation must be repeated every time the device is turned on.
Half Rate Codec:
Inclusion:
*4720# - Half Rate will be activated after the phone is overloaded (power consumption is reduced)
Shutdown:
#4720# - Half Rate will be turned off after the phone is overloaded
Enhanced Full Rate mode allows you to get much more best quality sound with the same number of bits of transmitted information, but loads your provider’s network more, the duration of the call time is reduced by about 5%
Half Rate mode degrades sound quality, but unloads the network and allows the provider to pass more calls through it, the duration of the call time increases by about 30%

Questions about Nokia Lumia 520 secret codes
Ask a question about secret codes for Nokia Lumia 520
Windows Phone- an operating system that is installed only on Microsoft products. It was this company that took over the assets of the famous and popular Nokia brand. Although buyer interest in this product began to rapidly decline, the manufacturer still released a series of mobile phones called Lumia. Surprisingly, it sold out quite quickly, and in considerable quantities. Therefore, these devices can be safely considered a kind of trump card for Finnish products.
According to most buyers, affordable option is Nokia phone Lumia 520. If you pay attention to its hardware, you will notice that it fully complies with modern requirements. It is impossible not to notice that Windows Phone 8 also attracts the interest of users. What are the features of this smartphone model? What characteristics will the Lumia 520 please customers with? The reader can find answers to these questions, and more, in this article.
Packaging and delivery
At first glance at the box in which the smartphone is transported, you can predict its attitude towards budget segment. The design of the packaging looks inharmonious. The designers clearly went overboard with the image of the phone, presenting it from different angles. This is what introduced a certain imbalance into the design of the box. Of course, the packaging contains information about the brand and model name. The main color remains the same - blue, and the text is printed in white. The back panel provides IMEI and WLAN data, as well as the firmware used on the Nokia Lumia 520. Instructions with detailed information about the gadget are included in the kit. The warranty card is printed on last pages this little book. What else will the buyer find inside the box? You should immediately pay attention to an important point - an entry-level device. For this reason, there is no point in counting on a unique set of components; the manufacturer has included everything you need in the kit. The set includes USB cable(CA-189CD), which is intended for connecting the device to a PC and other equipment. The smartphone is required to be equipped with a BL-5J battery and a charger (AC-20). The set also includes a WH-108 headset.
A little later we will discuss what emotions such a delivery kit caused, and what is missing from it, according to buyers. 
Design
Externally, the Nokia Lumia 520 phone is not much different from other devices in this line. The manufacturer has presented many color options on the market. For connoisseurs of classics, there are examples with black and white cases. For those who prefer bright colors, red, blue or yellow are suitable. It is important to understand that the variety of colors is provided only by the rear panel. It is made of soft-touch plastic. The material itself is quite high quality. Scratches and mechanical damage are practically not formed on the surface. However, according to most owners, to preserve the primary appearance you still need to use a cover. As for how dirty the surface of the back cover is, everything will depend on the color. The black version collects fingerprints more than any other. The most practical case turned out to be white.
Now let's look at the design features of the Nokia Lumia 520 smartphone, the characteristics of which are presented in this article. The front panel is designed quite typically. Most of it is occupied by the screen. Below it there is a touch control panel consisting of three buttons. They use generally accepted notations: Windows icon, “magnifying glass” (search) and arrow (back). Above the screen are only the speaker used for calls and the Nokia logo. There are mechanical buttons on the right side. There are three of them: volume swing, camera control, lock. Wired headphones can be connected via the audio jack located on the top end. There is a USB port at the bottom. The left side face is completely free of functional elements. Back cover served as a platform for the camera lens. According to a typical scheme, it is located in the upper part of the body. The login is printed along the lid. There is a speaker output hole in the lower right corner. By the way, we note that it emits a rather loud sound. 
Nokia Lumia 520: screen characteristics
When considering the screen characteristics, do not forget that the model was released in 2013. Naturally, the indicators will not be very good high level. The choice of display was also influenced by the fact that the device belongs to the class of inexpensive devices. So, the smartphone has a screen manufactured using IPS technology. Its 4-inch size fully corresponds to the resolution of 800 × 480 px.
What can you say about the image quality? Colors don't look bright enough. According to the owners, the contrast level is too low. Many users have noticed that black color does not appear naturally. It looks gray on the screen.
Multi-touch can recognize up to five touches made simultaneously. But in fact, after the third, the phone begins to get confused. This can be safely called a significant drawback. Note that setting up the Nokia Lumia 520 (screen calibration) does not solve the problem.
The manufacturer used special glass as protection. The film is not included in the factory configuration. There is no oleophobic coating, which greatly upsets the owners, since a lot of fingerprints quickly accumulate on the screen. 
CPU - hardware
Few people were surprised to learn that the manufacturer installed a Qualcomm Snapdragon processor on the Nokia Lumia 520. The characteristics of the S4 MSM8227 model will consist of rather modest indicators. It is based on two cores. The chipset will not be able to cope with most modern tasks. We are talking about resource-intensive applications. However, if you use the phone for its intended purpose, then problems will not arise. The computing modules of the processor are capable of accelerating to 1 GHz when the load increases.
An entry-level video card, Adreno 305, was chosen as the graphics accelerator. Its characteristics are also of a low level, but they will be sufficient for simple toys.
Memory
What do you need to save applications on Nokia Lumia 520? Of course, built-in memory storage. You can also take advantage of the potential external storage. In this model, the manufacturer chose 8 GB of integrated memory, which is complemented by the capacity of a microSDHC flash drive. The maximum capacity is 64 GB.
But what do the sizes mean? random access memory? This characteristic affects the operation of applications. In the Lumia 520 model it is only 512 MB. This is no longer enough to work with modern software. 
Photos for memory. Camera characteristics
Only one camera is available in the Nokia Lumia 520. The characteristics of the optics are limited by the capabilities of the 5-megapixel matrix. There is no photo flash. The developers have provided a fourfold zoom. It, of course, allows you to enlarge an area in the image, but the quality is greatly degraded. Photos can be taken in maximum resolution, which is 2592 × 1944 px. Video mode operates at a speed of 30 frames. The shooting is carried out in low quality - 720p (1280 × 720).
Autonomy
When choosing a smartphone, it is very important to pay attention to the battery characteristics. Every buyer knows that Finnish products have always had a long shelf life battery life. Was the Lumia 520 an exception?
The developers installed a battery on the gadget, made using modern lithium-ion technology. Its resource is 1430 mAh. The manufacturer claims that charging the Nokia Lumia 520 to 100% will take about 2-2.5 hours.
Now let's look at the characteristics of autonomy. According to the information in the instructions, the device will last 10 hours (3G) and 15 hours (2G) in talk mode. By switching the phone to standby mode, you can count on 15 days of operation. Under conditions of average load, the user will charge the battery no more than once every 48 hours. 
Platform and interface
