Mobile phone: history of creation, main functions and characteristics of modern devices. How to find out the specifications of an Android smartphone How to find out detailed information about a phone

The iPhone is locked to a European carrier. I would like to know information about the phone by IMEI code.

Hello Andrey

Where to get IMEI

You can see this code:

1. In the Phone application, after dialing the combination: *#06#

2. In the settings along the way: Settings - General - About device - IMEI.

3. On the back of the iPhone box.

4. On the back cover of the iPhone (for some models, IMEI is printed on the SIM card tray).

Of course, all codes must match, if a mismatch is found - a reason to think about the origin of the smartphone.

What to do with IMEI

On the Apple website, you can check the service eligibility of this model. See if the smartphone is covered by the warranty.

Detailed information on IMEI can be obtained on various sites and services, for example:

By entering the IMEI code, you can find out the device model, color and sometimes the amount of internal memory. The services will show if the device is listed as stolen/lost. Some sites may provide a serial number and warranty expiration date.

To get data about the operator to which the iPhone is locked, you need to know the model number ( Settings - General - About device - Model). You can check it on the indicated resources.

There can be several problems when buying a smartphone: for example, they may try to sell you not a completely new copy, and there is still a risk of running into a defective device. Below we have put together a few tips that will help you buy exactly what you need - a brand new and serviceable smartphone.

0. We study smartphone reviews and reviews on forums

Before you start looking for a marriage in a particular instance of a smartphone in a store, you need to find out what you should look at first.

There are enough forums on the Web where lists of possible shortcomings (marriage) of certain models, lovingly compiled by users, are published. Before going to the store for a smartphone, these lists should be carefully studied. And even rewrite it on a piece of paper - you never know, suddenly you forget something along the way. Do not underestimate these sources of information. The people are not the first day that you are just going to buy. And managed to collect statistics of marriage. For example, smartphone A may have problems with the camera, and smartphone B may have problems with the quality of the panel fit and the operation of the second SIM card. Would you have guessed to check these particular moments in the communication salon if you did not know about them in advance? Is not a fact!

As for smartphone reviews, we recommend paying special attention to the so-called unboxing or unboxing reviews. This is when a blogger on YouTube opens a sealed box, shows a brand new device in films and demonstrates what is included in the package.

What is the fundamental difference between a smartphone unpacking review and ordinary text reviews? Journalists often receive used devices for tests, and even without a box and a complete set. But unboxing implies a story about a completely new smartphone. Exactly the same as the one that will be offered to you in the store. While watching the unboxing, pay attention to the films: on some models they are glued only on the front, and on some - also on the back. It will show on the video. And if the store tries to sell you the device without one of the films, know that someone used it. Alas, this happens: sometimes dishonest sellers “drive” smartphones for the sake of interest, and sometimes they also try to sell the returned goods under the guise of a new one. And yes, the components of the package - adapters, headphones, cables, and so on - they sometimes pocket. So while viewing the review-unpacking, remember the package.

Keep in mind: smartphone X in the version for Russia may not have the same delivery set as in the version for the USA or, for example, China. So the priority is the videos of Russian authors.

1. We study the box with a smartphone and the condition of the films

Torn paper seals say only one thing: the box was opened. Why is an open question. Maybe the consultant decided to look at the device, or maybe - and use it. Why would you pay for a smartphone that looks like it's new but isn't?

The same applies to films: if they are not there or they are pasted crookedly and with bubbles, you should know that something is not clean here. However, there are exceptions: on very cheap devices, films are often pasted just crookedly and with bubbles. And it is not the sellers who are to blame for this, but the Chinese factories of the second or third echelon, which do not comply with the technological process.

2. Go to the call log, SMS and gallery

Life story: a girl bought a smartphone in a Russian online store, received a package, turned on the device and ... saw in her memory a couple of SMS messages, a pack of selfies of some young man and some more direct evidence that the device was used. Yes, he was brand new and in films, but someone - apparently, just for the sake of interest, since the model was exotic - turned him over in his hands. Some people will not pay attention to such trifles, but it will be unpleasant for someone. Therefore, before buying, you should see if there are any artifacts left from the uninvited "user" in the memory.

3. We are looking for scratches, dents and chips on the smartphone

Sometimes such artifacts are left by the same sellers, and sometimes the device comes with them from the factory. Scratches, chips and dents should be identified before purchase. Because they are not considered marriage: as soon as you pay for the smartphone, they will turn into your personal problem. If a faulty screen, camera, battery, and so on can subsequently be recognized as a defect and repaired or replaced under warranty, then scratches and other exterior flaws, if you do not see them right away, will not bother anyone.

4. Checking how the smartphone camera works

It is clear that it is worth taking a few pictures. In the store and, very desirable, also on the street. And then carefully examine them - so that there are no blurs in certain places, obvious spots, and so on.

But there is another life hack. A normal shot of a street or a store interior can be used to assess the quality, but it is not always possible to see a defect - after all, the picture will have a lot of details, bright colors, and so on. Therefore, take with you or ask the seller to give you a regular white sheet.

The fact is that various kinds of spots (pinkish, yellowish, bluish) on the frames are the scourge of many smartphone models. Such spots are perfectly visible just in the photographs of homogeneous white objects. Sometimes this is a software problem, and then you will encounter it in all instances without exception. At this point, decide for yourself: either take a smartphone and wait for firmware updates, or refuse to buy.

And sometimes it's iron. This means that one device can give such an unpleasant effect, while the other does not. Therefore, after detecting spots on the white sheet picture, you should ask the consultant to bring another copy from the warehouse. Maybe you'll be lucky.

5. Check the operation of the touch screen of the smartphone

To test the touch screen, go to the menu and click on all application icons without exception. They are located just over almost the entire display area. By clicking on them, you can identify the so-called blind spots - places where, for some reason, the sensor reacts poorly to pressing or does not react at all. The second option is to type text on the keyboard. First in vertical mode, and then in horizontal mode. Thus, you will also cover almost the entire screen area.

Note that recently such a marriage is extremely rare in smartphones, and yet sometimes you can encounter it. Especially in ultra-budget smartphones.

6. Checking the smartphone display for dead pixels

There are several options here. The first is with screen testing apps like DeadPixelTest. Everything is fine with them, but it is far from a fact that you will be able to install such an application on a device that has not yet been purchased. Sometimes store policy prohibits potential buyers from installing their software on smartphones, and sometimes it's just not very convenient. For example, if there is no Wi-Fi in the cabin or if you do not want to enter your account into your smartphone or register a new one specifically for testing.

In this case, you should prepare to check for broken pixels in advance. We take a MicroSD card at home and write several monochrome pictures on it - red, black, gray, blue, white, and so on. In the store, we insert the USB flash drive into the slot of the smartphone, go to the gallery and carefully look for "alien" points in the pictures. (At the same time, by the way, check if everything is in order with the slot and if the device recognizes MicroSD normally.) However, this method is also not universal: there are models (for example, OnePlus 5 and all iPhones without exception) that do not have slots for flash kart.

And yes, on a white and black background (most often on them), you can see not only broken pixels, but also various stripes - for example, yellowish or bluish. This is also a marriage. Below is a photo of such a strip posted by a user on the official Meizu forum.

7. Check the build quality of the smartphone

You can write a dissertation on how to check the build quality of a smartphone, and yet we will try to briefly highlight the most important points.

First, the glass covering the screen can be glued crookedly. In order to identify this moment in time, you should do the following. Firstly, at the same time run your fingers along the ribs - that is, in places where the side faces of the body merge with the front. The fingers should not feel any bumps or dents. Secondly, it is worth comparing the width of the slots around the screen. The gaps at the joints should be perfectly uniform. If the width is different - there are problems with the assembly. Thirdly, it is worth putting the smartphone on a horizontal surface and looking at it from the ends. If any irregularities were made during assembly, you will most likely notice that the front panel is installed unevenly.

Second: squeaks, dangling and backlash of the body panels are unacceptable. Even not the largest Chinese factories by 2017 have mastered assembly technologies that ensure the perfect fit of parts. If something dangles in the smartphone, then this is most likely a marriage. Request another copy.

At the same time, often even in not the cheapest smartphones, the volume and power keys rattle slightly. This moment should not be taken as a marriage - rather, it is just such an unpleasant feature. You can check if this is so by asking for a second device for comparison.

And one more thing: extraneous sounds (tapping) from the camera module are more normal than abnormal. These are the features of optical systems installed in smartphones.

8. Checking the operation of the audio part

Everything is simple with the speaker - I launched the pre-installed melodies, and if they are played, then everything is fine with the device. Do not trust the built-in ones - bring a MicroSD card with your favorite songs from home (provided that the device supports the flash drive). It is more difficult with headphones: individual manufacturers - the same company Xiaomi, for example - do not complete their smartphones with “ears”, which makes it difficult to check during the purchase process. Therefore, either demand headphones for a test from the seller, or, better, bring your own.

9. Checking the communication

With a cellular connection, everything is elementary: we put a SIM card and call someone. But do not hang up immediately after you hear "hello" on the other end of the wire. Talk for a couple of minutes - this way you will check the operation of the microphone.

And also pay attention not to whether the screen goes blank when you bring the smartphone to your cheek. If it does not go out, then the device has problems with the proximity sensor. This means that during a conversation, you will press your cheek on various elements on the touch screen. Pleasure is still.

It is more difficult to check the mobile Internet - practice shows that the glitches associated with it are floating, that is, in a number of models they appear from time to time. And not the fact that they depend on the smartphone. It may turn out that the mobile operator has problems.

To test Wi-Fi, you will have to connect to a wireless network - if it is available, of course. Another option is to turn on the traffic distribution mode, if it is supported on the smartphone that you have with you. An important point: if nothing is loaded either in the browser or anywhere else, you should not immediately consider the smartphone defective. Check the date and time: sometimes due to a long time in the warehouse, they go astray, in which case most Internet services do not work. Set the current year and the correct time in the settings - after that, most likely, everything will fall into place.

10. Check the battery

If the model has a removable battery, then it should have a white indicator. If there is no white, but there is red, then you should know that moisture has got into the smartphone. And it may turn out that he will not live long.

Also, for order, you should put the smartphone on charge for at least a couple of minutes - to make sure, firstly, that the interface connector is working, and secondly, that the charger is working.

Bonus track: testing a smartphone using special applications and codes

Google Play and the App Store have a huge number of applications for testing all smartphone systems. If the seller does not mind and the store has Wi-Fi - why not? Such applications will tell you everything about the screen, and about battery wear, and about the operation of sensors, and much more. For example, in the case of an Android smartphone, you can put Test Your Phone or Phone Doctor Plus. However, such software cannot be called absolutely reliable. For example, we tried to test the flashlight using one of these applications, and it reported that there was no flashlight in the smartphone (see screenshot below). Although it exists and works.

There are also so-called service codes - they are individual for each manufacturer, and sometimes for different models of the same company. They also allow you to learn a lot of interesting things about your smartphone, starting with system problems and ending with the total talk time. Lists of codes are easily searched on the Internet - just enter the phrase "service codes for a smartphone of such and such" into the search engine.

That's all. Nothing complicated. Enjoy the shopping!

The modern market is overflowing with cell phones. Sometimes it is even difficult to decide on the choice of device. After buying a smartphone, a situation may arise when you need to find out its model. Do not be upset if there is no documentation and box. There are several ways that you can find out the brand of your phone.

The simplest way to define a model

It doesn't matter which HTC or Samsung phone you have. You need to remove the cover and then remove the battery. Inside the phone is a sticker that contains the following information:

• Mobile device model;
• Serial number;
• Numeric code consisting of 15 characters. It contains information about the modification of the phone, the manufacturer, and the date of manufacture;
• Reference information (required for specialists of service centers).

It should be noted that in this way you can get information even about old mobile phones.

Receiving information through a digital combination

After purchasing a mobile device, you may notice that there is a sticker on the cover or battery. Most often, because of it, it is impossible to understand what is written on the case. You can determine the model of HTC or other phone. This can be done with a digital combination.

It is worth noting that each manufacturer has developed a specific code that allows you to get information about the device:

• Nokia: *#0000# - the code allows you to get information about the device model, production date, software version, and language settings;
• HTC: *#*#4636#*#* - the combination will display detailed information about the smartphone, including model and firmware;
• Samsung: *#8999*8379# (in some models *#1234#) - the display shows information about the device. In addition, the settings menu will open, but it is not recommended to change anything in it yourself;
• LG: 2945#*# - you will find out detailed information about your smartphone.

In the event that the buttons (touch screen) do not work on the phone, the above method does not suit you.

Determining the version of smartphones on the Android OS

Most modern devices have the Android operating system installed. You can take advantage of this. In fact, there are several ways to find out the phone model. The easiest way is to look at the information from the "About the device" section.

So, how to find out the phone model through Android? To do this, you will need to follow the following steps in sequence:

1. Go to the "Settings" section, which is located in the main menu;
2. Scroll through the list of settings to the very bottom, and then select "About device";
3. In the window that opens, view the data of interest.

It doesn't matter what mobile phone you have, HTC or Lenovo. From the settings you can find out the description:

• Models;
• serial number;
• Kernel versions;
• Build numbers;
• operating system.

The verified serial number and model can be written down in a notebook, and if necessary, use them.

Non-standard way of obtaining information

How to find out the phone model if there are difficulties with the above methods? To do this, you are recommended to use the Google Play service. To find out the modification of your phone, you need to download a utility such as Phone info. In addition to general information, you can see:

• Information about the firmware;
• Information about IMEI;
• Display parameters and the device itself;
• System data.

In addition, you can learn how to check additional information about the phone, thanks to the secret codes that the program will show. The code combination is available for all popular smartphones such as HTC, Nokia, Samsung and so on. Since it is not difficult to determine the brand of a phone, even a person using a smartphone for the first time will cope with the task.

From the article you will learn

The characteristics of the phone are the most important part, in addition to design, form factor, sensors, price and other points. But not all mobile phones have a built-in function with the ability to view full technical specifications. Fortunately, there are easy and free ways to get all the information about the technical side of a smartphone. To do this, you need access to the Internet and a special program or a search engine Google or Yandex.

What characteristics can be found?

Of course, we won’t be able to fully find out every detail, since almost all manufacturers hide them from our eyes, and it’s simply impossible to check this manually. For example, on iPhones, the battery capacity or core frequency is almost always unknown. This sometimes happens with Android smartphones.

Be that as it may, the most basic characteristics can be found. For example:

• Processor model, number of cores, their clock frequency, core architecture;
• Model of the graphics accelerator, its clock frequency and its own memory;
• The amount of RAM;
• The amount of built-in memory;
• Network support;
• Camera resolution;
• Resolution and screen size;
• Battery capacity.

Viewing methods

To view the characteristics of a smartphone, we need to have access to the Internet, a working official application store from Google called Google Play, or at least a browser. Alas, the specifications are not written anywhere in the smartphone system itself, as the developers hide them from the Settings application.

Some parameters can be found by reading them on the box. But, as a rule, very little information is indicated there.

There are a lot of ways to find out all the characteristics of the phone, but all of them are essentially divided into two:

1. Find out the characteristics of a smartphone on the Internet.
2. Download a special application from the Market for information.

For the first case, we need to know the phone model, and for the second, we need to download the utility. Both of these options are pretty good and suitable depending on the situation. Read more about them below.

The first way is through a search engine

In order to look up the characteristics of a phone through a search engine, you need to know the make and model. Fortunately, these two characteristics are present in the smartphone settings. To do this, follow these steps:

The search results will appear in front of you. You can open any convenient site and see the full data. For more detailed information, you can go to the topic of discussing the model on the popular w3bsit3-dns.com forum. To do this, simply write the smartphone model with the prefix "w3bsit3-dns.com discussion".

The second way is through the AIDA64 application

AIDA64 is the most popular app on Google Play that allows you to monitor the full performance of your gadget in real time.

You can download it completely free. But this version will have some ads. If you wish, you can buy the full version of the program for a little more than $ 1 (the price varies depending on the dollar and the country). The full version of AIDA64 only removes ads, it does not open up any new features.

After installing the application, open it. Inside we are waiting for a convenient menu with various data.

The main screen looks like below in the screenshot and it has:

To obtain specific characteristics, you need to go to the desired section and there will already be all the available information.

As you can see in the screenshot above, there are a lot of sections and they allow you to get the maximum data about the device. You will not find so much information on any site. There is even such unique information as the heating of the device (processor, battery, and so on). It will also be quite useful to learn about smartphone codecs and see the characteristics of applications, both built-in and installed during operation.

To view the model, brand, memory and information about the sensors, open the "System" window.

The "CPU" window contains all the data related to the central system of the smartphone: the processor, its architecture, frequency, number of cores, the strength of each core at the moment, and so on.

Consider each item separately in the following table:

In general, by examining each window, you can add up a complete picture of the gadget, having learned almost all possible information about it.

How to find out the characteristics of an android device? How much memory does he have? What processor is on my device? In this article, we will offer you a couple of solutions to answer these questions.

It happens that downloading app from the web (in APK format or from the app store), the downloaded software does not work, although it was installed correctly and without errors?

This may be due to the fact that unlicensed software is often made for certain graphics processors and even phone models. And in Probably your smartphone does not support the application's system requirements. With a minimum amount of information about the smartphone can be found:

• after reading the instructions that were included in the box with the purchased device;
• looking in the phone settings and reading the information in the section " About phone» (« Settings» -> « System» -> « About phone». On all devices there will be approximately the same path to system information). In this case, you will have to delve into the tabs. You will not get a clear summary of what you need, all the data will be scattered;

• take advantage specialized a program or utility for analyzing a smartphone.

Read the instructions and search for information on your android device you can on one's own. M We propose to consider programs for displaying detailed information about characteristics android device.

AIDA64 (Download)

The name AIDA is already familiar to many, as a similar PC program is often used to collect hardware data. The application allows you to get incredibly detailed and structured information about the android device, including temperature, codecs, sensors, system folders, battery. There is a lot of data and most likely only advanced users or specialists in the field of smartphone software will understand most of them. For a simple user, more than 60% of the information is simply not useful. Going through the tabs, you will sometimes have to look for the necessary data. There are ads, but they don't get in the way.

CPU Z (Download)

In CPU Z from xSoft Studio, information is presented in a more readable and understandable form for the average user. Display, sensors, CPU, memory, device and more - everything is there. But, unfortunately, additional and necessary functions (for example: "Network") are available only after purchasing the full version of the program. The most common, simple program. There is nothing special or unique.

AnTuTu Benchmark (Download)

A great program that allows you not only to see the characteristics of the android, but also to test your device in the most severe conditions and compare it with other models. Characteristics are displayed only the most necessary, basic and understandable. There are no unnecessary and incomprehensible abbreviations.

Testing is carried out using the maximum load of the central and graphic processor. The speed of transferring and receiving data both from the internal storage and from the network is taken into account.

A heavy load is used as a load, high poly 3D video. During the test, the phone will get very hot. On weak devices, the picture on the screen will freeze a lot. Don't be afraid, that's the way it should be. When finished , you will see the device 's score , which describes how it compares performance your device.

A test using 3D models is possible only after installing an additional program AnTuTu 3DBench (Download), which is essentially an extension for the main application. Without extension , only simple tests are possible . You can, for example, test multitouch.

AnTuTu Benchmark offers to download another additional extension AnTuTu Officer (Download). After doing a few manipulations with the computer and the QR code, it will show whether your phone is gray or not.

Droid Info (Download)

good program, providing equipment information and characteristics android devices. Shows only the main characteristics with a small extension. The application is working, but needs some improvement (it does not always give correct information, especially about new devices). And the last update is dated July 24, 2016. It seems that the developers abandoned their creation, but in vain. The interface is very convenient and simple , the necessary information can be found in a couple of seconds . It is possible to send a detailed report about the device (in the form of text) to the mailbox - a strange feature, but it can come in handy.

CPU -Z from CPUID (Download)

Almost identical to Droid Info program, only in English. Unlike the latter, CPU -Z is regularly updated and maintained by the developers. The information is accurate and correct, everything corresponds reality. For those who do not know English, it is better not to download, there are a lot of technical names. By the values ​​themselves, one can guess what characteristic is being discussed, but still not always.

Geekbench 4 (Download)

Another powerful tester performance phone similar to AnTuTu Benchmark. Provides only the main characteristics of the android device: model, memory size, firmware, graphics processor, number of cores, etc. (sensor readings and changes in processor temperature will not be seen here). Has the ability to check performance device under load. Unlike AnTuTu , the application does not require additional installation of extensions .

Choosing program to view the characteristics of your android, it is worth proceeding from your needs. Is it really necessary to have information about the exact temperature values, readings of sensors on the processor cores? It is worth trying all the applications and finding the right and most convenient one, specifically for your needs.
