Many manufacturers recognize the marriage of the matrix if there are more than five defective points - in this case, in the store you must replace the device for a good.

In this article we will tell you how to check the phone on broken pixels, and what to do to eliminate the problem.

To begin with, we note that the broken and burning pixels differ from each other:

• boyed - black, extinct dots that are not subject to recovery;
• last minute - bright, luminous and highly noticeable points that can be restored by software.

There may be several problems when buying a smartphone: for example, you may try to sell not quite a new copy, and there is also a risk of running into a defective device. Below we collected several tips to help buy exactly what you need is a new and serviceable smartphone.

0. We study the reviews of smartphones and reviews on forums

Before you begin searching for marriage in a specific instance of a smartphone in the store, you need to find out what should be viewed first.

There are enough forums in the network, which are published lovingly compiled by users of the lists of possible shortcomings (marriage) of certain models. Before going to the store for a smartphone, these lists should be carefully learned. And even to rewrite on a piece of paper - you never know, suddenly, on the road, forget. 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 marriage statistics. For example, a smartphone and there may be problems with the camera, and the smartphone is in the quality of the panels and the work of the second SIM card. Would you guessed to check exactly these moments in the cabin, if they did not know about them in advance? Is not a fact!

As for smartphones reviews, we recommend paying special attention to the so-called unpacking unpacking. This is when a blogger on "Youtyuba" opens a sealed box, shows a brand new apparatus in the films and demonstrates what is included in the package.

In what fundamental difference Review-unpacking of a smartphone from ordinary text reviews? Journalists are often obtained on the tests of used devices, and even without a box and configuration. But the angoxing implies a story about a completely new smartphone. Exactly the same as the one that you will be offered in the store. During the viewing of the atomication, pay attention to the films: they are glued to some models only in front, and on some - also behind. On video it will be noticeable. And if in the store you will try to sell the device without one of the films, know: someone used them. Alas, it happens: sometimes smartphones of interest for the sake of "chasing" sellers are unclean on the hand, and sometimes they are trying to sell the returned goods under the guise of a new one. And yes, the components of the configuration are adapters, headphones, cables, and so on - they sometimes embarrass. So while viewing a review-unpacking remember a complete set.

Keep in mind: Smartphone X in the version for Russia may not have such a set of delivery, as in the version for the United States or, for example, China. So in priority - videos of Russian authors.

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

Torn paper seals speak only one thing: opened the box. Why - an open question. Maybe the consultant decided to watch the device, and maybe - and to use it. Why do you pay for a smartphone, which seems to be new, but not really?

The same applies to the films: if they are not or they are crooked and with bubbles - know something is unclean. However, there are exceptions: at all cheap films, the films are often stuck just crooked and with bubbles. And the sellers are blamed not to blame for this, but the Chinese Factories of the second-third echelon, which do not comply with the technological process.

2. Go to the log of calls, in SMS and in the gallery

History from life: The girl bought a smartphone in the Russian online store, received the parcel, turned on the device and ... I saw a couple of SMS in memory, a pack of Selfie some young man and a few more direct evidence that the device was used. Yes, he was new and in the films, but someone is visible, just for the sake of interest, since the model was exotic - he turned it in his hands. Some people will not deal with such little things attention, and someone will be unpleasant. Therefore, before buying it is worth seeing whether there are no artifacts in the memory remaining from the uninvited "user".

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

Sometimes such artifacts leave all the same sellers, and sometimes the device comes with them from the factory. To identify scratches, chips and dents should be purchased. Because they are not considered marriage: as soon as you pay for your smartphone, they will turn into your personal problem. If a defective screen, camera, battery and so on may later recognize the marriage and repair or replacing the warranty, then scratches and other exterior deficiencies, if you did not see them right away, will not worry anyone.

4. Check how the smartphone camera works

It is clear that you should take a few pictures. In the store and, very desirable, also on the street. And then carefully examine them - so that there are no blur in separate places, obvious spots and so on.

But there is another lifehak. On the usual snapshot of the street or the interior of the store you can evaluate the quality, but it is not always possible to see the marriage - because the picture will be a lot of details, bright colors and so on. Therefore, capture with you or ask the seller to give you an ordinary white sheet.

The fact is that all sorts of stains (pinkish, yellowish, bluish) on frames - the Beach of so many models of smartphones. Such stains are perfectly visible at the pictures of homogeneous white objects. Sometimes it is a software problem, and then you will meet it in all instances without exception. There yourself decide: or take a smartphone and wait for firmware updates, or refuse to buy.

And sometimes the case is in the gland. This means that one apparatus can give such an unpleasant effect, and the other is not. Therefore, after detection of stains, the white sheet should be asked to ask the consultant to bring another instance from the warehouse. Maybe lucky.

5. Check the work of the touchscreen smartphone

To check the touch screen, go to the menu and undermine everything without exception icon of applications. They are located just almost all over the area of \u200b\u200bthe display. Pressing on them, you can reveal the so-called blind spots - places where for some reason the sensor responds to pressing poorly or does not respond at all. The second option is to peak the text on the keyboard. First in vertical mode, and then in horizontal. Thus, you also entertain almost the entire area of \u200b\u200bthe screen.

Note that in lately A similar marriage is found in smartphones extremely rare, and yet sometimes you can face. Especially in ultra-budget smartphones.

6. Check the smartphone display on broken pixels

Here are several options. The first - using applications for checking screens like Deadpixeltest. All with them is excellent, but it is far from the fact that you will be able to put a similar application to a not yet purchased device. Sometimes store policies prohibits potential buyers to put their software on smartphones, and sometimes it is simply 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 specifically for testing.

In this case, you should prepare for checking on broken pixels in advance. Take at home microSd map And write down several monophonic pictures on it - red, black, gray, blue, white, and so on. In the store insert the USB flash drive in the smartphone slot, go to the gallery and carefully looking for "alien" points in the pictures. (At the same time, by the way, check whether everything is in order with a slot and whether the device is normal recognizes microSD.) However, this method is also not universal: there are models (for example, onePlus 5 and all without exception), in which there are no slots for flash- kart.

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

7. Check the quality of the assembly of the smartphone

On how to check the quality of the assembly of the smartphone, you can write the dissertation, and still try to briefly highlight the most important points.

The first: the shelter screen glass can be glued crooked. To reveal this moment in time, the following should be done. First, simultaneously spend your fingers along the ribs - that is, in places where the side faces of the housing are closed with frontal. Fingers should not feel bumps, nor dents. Secondly, it is worth comparing the width of the slots around the screen. The slots at the joints should be perfectly uniform. If the width is different - there are problems with the assembly. Thirdly, it is worth putting a smartphone on a horizontal surface and look at it from the ends. If any violations are allowed when assembly, you will most likely notice that frontal panel Installed unevenly.

Second: screens, chat and the play of the housing panels are not allowed. Even not the largest Chinese factories by 2017 mastered the assembly technologies that ensure the perfect fit of the details. If something dangles something in the smartphone, then it is most likely marriage. Require another instance.

At the same time, often even in non-cheap smartphones, the volume and inclusion adjustment keys are slightly rattling. This moment is not perceived as a marriage - rather, it is just such an unpleasant feature. Check if it is possible, it is possible to ask the second apparatus for comparison.

And further: outsided sounds (Tapping) From the camera module - it is rather normal than abnormal. These are the features of optical systems installed in smartphones.

8. Checking the work of the audience

With the speaker, everything is simple - launched pre-installed melodies, and if they are played, then everything is fine with the device. Do not trust the built-in - carry from home MicroSD card with your favorite songs (provided that the flash drive unit supports). With headphones harder: individual manufacturers - the same company Xiaomi.For example, our smartphones "ears" do not complete, which makes it difficult to check in the purchase process. Therefore, or require headphones for the test of the seller, or, better, bring your own.

9. Check the operation of communication

FROM cellular connection All elementary: we put the SIM card and someone call. But you should not throw the phone immediately after you hear "Hello" at that end of the wire. Talk a couple of minutes - so you check the operation of the microphone.

And even pay attention not to whether the screen goes out when you bring the smartphone to the cheek. If it does not go out, then the device has problems with the approximation sensor. This means that during the conversation you will press the cheek to various items on touchscreen. The pleasure is still.

Mobile Internet Check more difficult - Practice shows that the glitches associated with it have the character of 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 be that the problems of the cellular operator.

Wi-Fi testing will have to connect to wireless network - If it is, of course, is available. Another option is to include traffic distribution mode, if so is supported on the smartphone that you have with you. Important moment: If nothing loads neither in the browser, no one else, you should not immediately consider the smartphone defective. Check the date and time: sometimes due to a long lying in the warehouse they are knocked down, and in this case most of the Internet services do not work. Set the current year in the settings and right time - After that, most likely, everything will fall into place.

10. Checking the battery

If the model is a removable battery, then it should be an indicator of white. If there is no white, and there is red, then you know moisture into the smartphone. And it can be that long he will not live.

Also, for the order, at least for a couple of minutes, put a smartphone for charging - to make sure, first, in the serviceability of the interface connector, and secondly, in the serviceability of the charger.

Bonus track: We test the smartphone using special applications and codes

In Google Play and App Store. there is great amount Applications for testing all smartphone systems. If the seller is not against and in the store there are Wi-Fi - why not? Such applications will tell you everything about the screen, and about the wear of the battery, and about the operation of the sensors, and much about what else. For example, in the case of an Android smartphone, you can put Test Your Phone or Phone Doctor Plus. However, it is absolutely difficult to call such a software. For example, we tried to test the work of the flashlight using one of the similar applications, and it reported that there is no flashlight in the smartphone (see the screenshot below). Although it is and works.

Still there are so-called service codes - They are individual for each manufacturer, and sometimes for different models The same company. They also allow you to learn about the smartphone the mass of everything interesting, starting with problems in the system and ending with the overall time of conversations. Code listings are easily searched on the Internet - just enter the phrase "service codes for a smartphone such" in the search engine.

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

We like our phones so much that they are ready to post all the money just our phone was better. But why spend money when it's not necessarily? So, if you noticed broken pixels on your communicator, then do not rush to spend money on repairs. First, try my method for "cure" Mobile Phone Display.

What are the varieties of bad pixels:
- broken pixels (black, extinct squares on the display)
- Last minute pixels (bright, luminous pixels, unpleasantly watching and very noticeable)
- dependent pixels (noticeable only if the chess board or grid screen)

Unfortunately, the reason for their appearance is the initial malfunction in the development.
In order to find and cure your favorite phone, you will have to download the PocketlCD application. The program is absolutely free and does not require any authorization. Swing here.
This application will help to find broken pixels - simply shows one color on the screen, thereby immediately notice if some square will be different. This program will help to avoid misunderstandings when buying a new device.

So, consider two methods of treating pixels:

1. A dangerous way, but not rarely saving display.
- Find a bad pixel using the program
- Now you need to "massate" the place where there is bad pixels. This can be done: it is better fine with a cotton wand, but some use fingers, sharp items (only very careful!) - Last options can only cause harm.
- If you did everything neatly, with a cotton wand, then, most likely I have already restored your broken pixel
Unfortunately, if you overdo it, you can only get new broken pixels.

2. Software. It happens that broken pixels appear due to the freezing of blocks in the pixel area. In order to "cure" pixel, use the instructions:
- Download the JScreenFix app here
- Run the program
- After 20 minutes, turn off the execution of the program (if it does not help, leave for 5-6 hours)
- In most cases, a broken pixel disappears
Good luck! If it does not work, then you are direct road to the service center.
