According to statistics, those that appeared on the screen as a result of not too careful handling mobile gadgets cracks are the most common reason for contacting repair shops. And this is not surprising, because the display is the notorious Achilles heel for any, even the most expensive and famous mobile phone. What to do if touch phone The screen is cracked, let's figure it out together. It’s better not to risk it and immediately replace it https://meizu.telemama.ru/zamena-stekla-na-meizu-mx.html

What to do if your phone screen is cracked?

So, there is a problem - after a fall, cracks appeared on the screen of the mobile phone. How to act in this situation and how dangerous are they for both the phone itself and its owner? It all depends on the degree of damage received. For example, if there are one or two cracks, and they do not interfere with the normal operation of the mobile gadget, it is quite possible to do with half measures - stick a protective film or glass over the screen. In this form, the phone will be able to work for some time. for a long time, and dust and moisture cannot get into it through the cracks. But if the screen is covered with craquelure of tiny cracks, then you cannot do without a visit to a repair shop. Fully restore functionality touch screen is possible only if it is replaced using special equipment. At the same time, you need to be prepared for the fact that replacing a cracked smartphone screen can result in expenses equivalent to half the cost of a new mobile phone. Therefore, in some cases it makes sense to think about replacing a broken gadget with a new one.

Is a cracked phone screen harmful?

Mobile technologies appeared not so long ago, but immediately became overgrown with many myths and speculations regarding the harmful effects on the human body. In particular, one can often hear the opinion that cracked screen turns the phone into a time bomb. But in fact, the only harm it could hypothetically cause is scratching the owner’s skin during a conversation.

I dropped the phone, the protective glass cracked (I think the display itself is intact, because shadows from the cracks are visible on the display itself, the display itself works great, there are no broken pixels, the screen responds perfectly to pressing over its entire area). The authorized service center claims that you still need to change the display, because... This protective glass is included in the video module, and this is 50%+ of the cost of the phone. He spoke the truth on the phone, because... The service center is quite far away

I was repairing push-button phones, there would simply be a solution to replacing the front panel or case, but there was no need to deal with touch sensors, service manual for this phone(DNS S4704) I didn’t find it, I tried to disassemble it, but when I started the process of disconnecting the front panel, the protective glass began to crumble and crack, so I didn’t do it until I didn’t have the components.

If your gadget does not have a protective glass, and you accidentally made a scratch due to negligence. Don't despair, we've put together a few lifehacks on how to remove scratches from your phone or tablet screen. There are many effective tools for this, including the simplest and most widely available, and technologically complex ones.

Basic methods for removing scratches

Glass and plastic displays are prone to polishing (we'll look at how to polish a screen using specific methods below). The same can be said about the protective glass of the camera lenses of mobile devices.

The choice of polishing method for the screen or camera depends on the depth of the scratches and their total number.

Conventionally, methods that allow you to remove scratches from your phone can be divided into 2 groups:

1 Chemical. At the same time, they can be further classified:

Those that involve the use of commonly available means that almost every homeowner has:

  • toothpaste;
  • soda;
  • vegetable oil.

And those that involve the purchase of specialized (but at the same time common) chemical reagents and means household chemicals, namely:

  • baby powder (talc);
  • GOI pastes and its analogues (for example, Displex);
  • car polishes;
  • potassium sulfate.

2 Mechanical. They involve the use of:

  • sandpaper;
  • drill or grinder.

Let's study in more detail how to remove scratches from a camera on a phone or from the screen of a mobile device using the specified methods.

Attention! You decide at your own risk whether or not to use the methods described in the article. We cannot be held responsible for possible damage to devices resulting from the use of these methods for cleaning displays and cameras of mobile devices.

Restoring the screen using improvised means

You can remove minor scratches on your phone camera or gadget display using the most affordable means at home. It is assumed that such products will have the least impact on the surface (small and small scratches can be effectively removed).

We are talking about the application:

  • toothpaste;
  • soda;
  • vegetable oil.

Applying toothpaste

A small amount of it should be applied to the display or protective glass of the camera lens using a cotton pad. Then, using circular movements (if scratches are observed over a large area) or back and forth movements with light pressure, you need to process the display, “erasing” any minor damage.

It is best to use classic mint paste.

Fig.1. We clean the device with paste.

Using baking soda

If toothpaste does not help, then you can use another commonly available remedy - baking soda. The technology for cleaning the screen of a tablet or smartphone will be similar here, but instead of a cotton pad, it makes sense to try a foam sponge or soft cloth.

Important! Soda should be slightly moistened before use. Dry powder can damage the smartphone screen, fall inside through the cracks in the case and disrupt the operation of the device.

Rice. 2. “Soda” effect.

The advantage of soda is that this product acts on the surface of the screen somewhat harder than paste, and therefore allows you to clean deeper scratches from the screen.

We use vegetable oil

Another remedy that is almost always on hand at home is regular vegetable oil. It does not have an abrasive effect like paste or soda, but it helps effectively get rid of small scratches on the display glass.

You need to apply literally a few drops of the product to the mobile phone screen, and then rub it with light movements on the damaged area of ​​the display.

Important! The most important thing is not to overfill the oil - if it gets inside the device, it will be extremely difficult to remove it.

The hardware store will help

If removing scratches using the handy tools discussed above does not help, you may have to visit a hardware store to purchase the following chemicals:

  • baby powder or talcum powder;
  • GOI paste or its analogues;
  • car polish;
  • aluminum potassium sulfate.

Apply baby powder or talcum powder

Among users of mobile gadgets, there is an opinion that baby powder is cheap and cheerful, however, the effectiveness of its use is confirmed by practice. main feature powder is that it involves a polishing method that, on the one hand, is quite harsh (since the powder contains solid particles), on the other hand, allows one to avoid the occurrence of collateral damage (since the powder particles are very small and cannot cause a noticeable scratch).

Using GOI or Displex paste

These funds are specialized. They polish glass and plastic equally well. At the same time, to remove scratches from a smartphone camera, it is considered more effective to use GOI paste, and to clean the display - Displex.

Rice. 3. Displex – optimal for touchscreens.

Application of car polishes

Products similar in effect to GOI and Displex pastes are car polishes. Popular brands of such products used to clean displays from scratches include Turtle Wax and 3M Scratch Removal. Car polishes are among the best products for removing deep scratches from displays.

The mechanism for using the above products - GOI pastes, Displex, polishes - is the same. Apply a small amount to a soft cloth, then polish the surface.

Please note that the use of the above polishes may require the purchase of additional specialized products - for example, car wipes.

Use of aluminum potassium sulfate and egg white

Among the exotic “chemical” methods of removing scratches from screens, which are used by enthusiasts in the field of mobile electronics, we can highlight the use of a mixture of these substances.

Rice. 4. The main thing is not to “sour” the screen.

Aluminum-potassium sulfate (also called “potassium alum”) is an inorganic substance used in the leather industry as a tanning agent, in the textile industry, and in the cosmetics industry. You can buy it in a chemical reagent store, including in an online store (for example, https://lenreactiv-shop.ru).

You need to take 1 egg white and 1 teaspoon of aluminum-potassium sulfate. Then mix them in a small container, pour into an aluminum cup (plate) and heat to 65 degrees. Then you need to dip a piece of microfiber into the solution, then dry it in the oven, which is heated to 150 degrees (while placing it on aluminum foil).

Then cool the microfiber by dipping it in water, then leave it to dry at room temperature for 2 days.

The entire procedure must be repeated 3 times. Using a piece of cloth treated with the specified chemicals, rub the damaged surface mobile device. Remove minor scratches and damage.

The advantage of this method is that there is no need to use additional chemicals.

Let's now study how to remove scratches from a tablet or similar device using mechanical methods.

Mechanical means

In advanced cases - if there are deep scratches or if the phone could not be protected from chips on the screen, it is advisable to use “heavy artillery” in the form of mechanical methods for removing damage from the display (we note right away that they are not suitable for cleaning the camera). We are talking about the application:

  • sandpaper;
  • drill, grinder.

Removing scratches using sandpaper

The purpose of its use is to gradually erase the damaged surface to a depth corresponding to the depth of the scratch. As a result, the scratch simply ceases to exist.

Another question is whether the screen, thoroughly processed with sandpaper, will look aesthetically pleasing. It is clear that if, for example, an iPhone is scratched, it is not at all convenient to remove scratches using the method in question. But if you need to bring an old gadget into more or less “saleable condition,” the method will come in handy.

Rice. 4. Is the method tough but fair?

We use a drill (with a felt roller), a grinder (with special attachments)

The main function of such devices is to greatly enhance the effect of using the “chemical” tools discussed above by automating polishing. If the user, who tried manual polishing, did not succeed, and he does not know how to remove scratches, it makes sense to use the appropriate auxiliary devices.

Working at hundreds of revolutions per minute, a drill or grinder can provide incomparable results compared to the manual method.

Summarize

Thus, there are a large number of ways to “renovate” the screen of a mobile device from scratches. Let's now try to display the main features of their use in a small table.

Method for removing scratches from a phone (mobile device) Features (what to look for)
Polishing with paste You need mint paste, preferably one color
Polishing with soda Soda needs to be moistened with water
Vegetable oil treatment The main thing is not to overfill (otherwise the drops will get inside the device and it will be extremely difficult to remove them)
Use of baby powder, talcum powder Excellent solution for removing light scratches
Polishing with GOI paste Allows you to clean the camera on your phone in the most effective way
Application of Displex paste Optimized for display cleaning
Application of car polishes May require the use of a special cloth tool for rubbing

So, we have learned how to get rid of scratches on your phone screen. Both the simplest household substances - vegetable oil, soda, baby powder, and more complex types of household chemicals and reagents (such as a substance based on potassium sulfate) can be effectively used to remove scratches from both displays and protective glass of cameras on mobile gadgets.

At the same time, we must remember that prevention is always better than “cure”. Behind mobile device needs care. It is necessary to ensure careful storage of the device. So, good case will protect the case, and a special protective film helps keep the display safe and sound.

Any barely visible scratch should be removed immediately. We have studied in detail how to remove a scratch on a phone screen - the most accessible means can be used for this.

Often, when touch phones or tablets are handled carelessly, cracks or so-called “cobwebs” appear on the front panel of the device after unwanted contact with asphalt or other hard objects. Here we will try to explain what to do and how to understand what has broken.

1. Cracks appeared on the front part. Can it be replaced?

We are often mistaken in thinking that the front of the device and the sensor are two different parts. This is wrong. The front part of touch phones is the touch glass itself (touchscreen). There are cases when, after a fall, the touchscreen continued to work, although it had visible damage. But, as a rule, over time, spontaneous clicks, incorrect reactions to touches, or complete inoperability appear. If your front part is broken (also called protective glass, not to be confused with protective glass that is glued instead of film), then you will have to change the touchscreen (sensor).

2. The sensor is broken, but the display works. Will it be possible to just change the sensor?



There are models that have a module where the touchscreen is “glued” to the display. This depends on the model of your device.

3. And then they change the sensor on the module!


There are times when a person, having come to the Workshop and heard the cost of replacing a module, is indignant that in some Workshop they change everything separately. Replacing the touchscreen separately from the display when the module is installed is quite possible and practiced, but no technician can give a 100% guarantee that the procedure for removing your old, broken touch glass will be successful; often in the process of “unsticking” it is damaged and breaks display and replacing the entire module cannot be avoided. And the final cost of repairs to replace the sensor glass in the module is not significantly different than replacing the entire module.

Briefly about the main thing:

1. By breaking the front panel of a touchscreen phone, you have broken the sensor itself (touchscreen). That’s why it is it or the entire display module that changes (depending on the device model).

2. If, after a fall and cracks appear on the sensor, it continues to work, remember that this is temporary. The slightest further damage can disable it. So, it is advisable to replace it as soon as possible while the phone is still working. Or at least extract from such a device all the information that is important to you (photos, videos, contacts), if repairs are not planned in the future.

3. In models that have problems with the module (sensor and display), it is better to immediately replace the module.

4. Having saved on the quality of parts once, you risk paying again soon, and for a larger amount.

Even if you use mobile phone be very careful, scratches sometimes appear on it. Small and invisible damage to the touch screen can cause discomfort to the owner during operation. What should you do if these flaws appear on the display, and how to care for your gadget so that even after long-term use it looks like new?

The most common causes of damage

A new smartphone rarely manages to maintain perfect appearance for a long time. Back panel The device is usually erased, and small “abrasions” appear on the display. What leads to their formation? Large cracks are most often caused by the phone falling from a height onto a hard surface. This mostly happens by accident, for example, when the owner drops the gadget while trying to get it out of his pocket or purse.

It should also be remembered that scratches can result from contact of the screen with hard objects - for example, keys, a lighter, and even small change. Therefore, it is important to carry your smartphone in a special case in a separate pocket. Also, your fashionable gadget will quickly lose its presentation if you take it with you to the beach. Even the smallest grains of sand are hard enough to leave damage on the surface of the display.

Ways to get rid of scratches

You can remove scratches at any service center, where specialists can restore the damaged screen to its original appearance. But you can try to do this at home.

We must immediately warn you that removing scratches from a touch screen using these methods is always risky. Therefore, before you begin, consider whether you can carefully carry out the necessary procedures.

Useful information: Before you begin to remove scratches from the touch screen, close all connectors on the phone to prevent moisture or foreign objects from getting into them. This can be done using regular tape.

Toothpaste or powder


Toothpaste can help get rid of minor scratches

The most common option for removing scratches from a touch screen involves using tooth powder or toothpaste.

To get rid of flaws in this way, you need to apply a thin layer of paste or powder to the display and rub the product into the display in a circular motion. Then you need to wait until the substance on the screen is completely dry. Finally, you need to wipe the display with a damp cloth or cotton pad.

After this, small scratches will become less noticeable. But if there is deep damage to the touch screen, you will not be able to get rid of it using this method.

Baby powder or baking soda


Baking soda is also used to remove damage from the display.

These two points can be combined into one, since they differ only in the ingredients, but the principle of application is the same. So, to remove scratches from the screen, dilute baby powder or baking soda to a mushy consistency and use a cotton pad or sponge to apply the mixture to the damaged areas of the screen. Then wipe off any residue with a tissue and wipe the display dry.

Sunflower oil


Sunflower oil will restore the lost shine to the screen

This method is less effective than the others. Using vegetable oil can only get rid of minor scratches, and even then only for a short time. But there are also advantages: after applying the oil to the screen, it will acquire its former shine.

Car and furniture care products


Special car care products will help remove shallow scratches from your touch phone screen

Polish and special furniture care products can also be used to remove scratches from the touch screen. Apply the selected product to the phone screen and use a cloth to polish the surface. You can also use furniture polish for the same purpose. Efficiency this method depends on the depth of damage on the screen and the quality of the selected polish. Judging by the reviews, the described method helps get rid of superficial scratches that are shallow in nature.

Sandpaper


Sandpaper must be used very carefully

This method seems simple only at first glance. In fact, only patient and careful people should use it.

Abrasive fine-grained sandpaper is ideal for polishing. It must be used as a roller. In the process of polishing the screen, do not rush in any way, so as not to spoil it.

Useful information: After the work has been done, you will notice that the touch display has become dim and matte. Sandpaper gives this effect. To restore the screen's shine, apply a little GOI paste to it. After completing the procedure, wipe the screen with microfiber.

Paste GOI


GOI paste is the most effective remedy

GOI paste was created back in Soviet times at the State Optical Institute. This is a fairly soft abrasive material that is used for polishing ceramic, metal and optical products. It is also suitable for smartphone displays.

This paste is perhaps one of the most effective and affordable materials for polishing a touch screen. When choosing GOI, consult with the seller, since there are 4 different types of this substance. It must be applied to the surface of the touch screen with a special cotton cloth or napkin.

To begin, take a small amount of paste on a cloth and wipe the touch screen without pressing too hard. Do not hurry. Apply the abrasive in layers, one after the other. It is advisable to take short breaks and let the paste dry. The desired effect may not appear immediately. After completing the procedure, wipe the screen with a previously used cloth (do not forget to rinse it in clean water before doing this). Finally, wash your hands thoroughly.

Special products for polishing displays


Special products for polishing displays can be bought at any hardware supermarket.

Special products were invented to remove various scratches from the screen better than others. We recommend purchasing a polishing substance for touch screens at any hardware store. This product will not completely remove the scratch, but it will help hide it. Any damage to the display will become less noticeable.

Suede


The effectiveness of using suede is extremely doubtful

Despite the positive reviews, this method is less effective than most. A soft cloth will not help you get rid of noticeable scratches, no matter how much you rub it on the screen.

For devices with tempered glass (Gorilla Glass)


Gorilla Glass - impact-resistant glass for smartphones

This method is ideal for removing scratches from screens made of protected Gorilla glass Glass. This material is more durable than regular material, but, unfortunately, it is not immune to scratches. The main disadvantage of Gorilla Glass is that it is difficult not only to scratch it, but also to get rid of the damage. Toothpaste definitely won’t help here; you’ll have to use more radical methods.

You should think about bringing the Gorilla Glass touchscreen into proper shape only as a last resort: if the display is severely damaged and scratches prevent you from using your smartphone. Instead of replacing your screen, try polishing it. Polishing your display at home will help you save a lot, and the risk of worsening the damage is minimal.

Grinding machine in combination with GOI paste


A grinding machine and GOI paste will help remove scratches from Gorilla Glass

A sander will help remove scratches more smoothly. Thanks to the high rotation speed of the tool, you will be able to polish the screen efficiently and eliminate even the largest and most noticeable defects. If you don’t have such a tool at hand, you can use a simple drill.

First, use a sponge or microfiber cloth to create a buffing wheel (called a roller). Apply a thin layer of paste onto it and proceed to polishing.

Helpful advice: Start with low speeds, constantly monitor the process. Do not polish one area of ​​the display for too long, as you may overheat the glass.

Preventing scratches on the display


To avoid scratches on your smartphone screen, remember the prevention rules

In order to avoid even the smallest damage to the screen, it must be properly cared for from the first days of use. Follow a few simple rules. Namely:

  • From the first day of use, keep your phone in a silicone or rubber case.
  • Be sure to put a protective film on the screen.
  • Do not take your smartphone with you to the beach and do not carry it in the same pocket with keys and other metal objects.

Using protective film

To protect the screen, you can use either a special film or stationery tape. The second option is more budget-friendly. To apply a strip of tape to the screen, it is important to precisely cut a piece of the desired size. And remember: if you apply the tape carelessly, the phone will look terrible.

It is better, of course, to use a special protective film, and you should not save money when purchasing it. To hide all scratches, use a film with a silicone base. It will fill in small scratches on the screen, making them invisible. It is better to do this immediately after purchasing a smartphone; replacing the screen will cost much more.

It is worth noting that all of the above methods for removing scratches from a phone’s touch screen are only suitable for shallow scratches. And do not forget that if you use many of the methods suggested above ineptly, you can completely ruin the screen and make scratches more noticeable. Therefore, before you start eliminating screen defects at home, think carefully about whether you can do it carefully and accurately. To make sure you don't damage your favorite phone, first try the method you choose on any old phone.

A modern smartphone is a fragile thing, especially its screen. The tempered glass that covers the displays for protection is almost resistant to scratches and light impacts somewhere in the middle. But from landing on a hard surface, and even if the smartphone hits the corner or edge of the screen, it’s easy to break it. Sometimes only the glass cracks, while the display itself continues to show the picture normally, and sometimes the image disappears. In some cases, the sensor remains in working condition, and in others, it stops responding to the finger.

There are several options for damage, and what to do if you break your smartphone screen depends on the type and scale of the damage. Therefore, let’s try to figure out what’s what and draw up a further course of action. It should be noted right away: if certain areas of the display do not work, there is no need to try to make it respond to your fingers by increasing the pressing force. After all, you can cut yourself on a chip or drive small pieces of glass into your skin.

What to do if the screen and sensor are working

If you break the screen of your smartphone, but it continues to show the picture, and the sensor responds to your fingers, there are two options. If the device does not have an air gap between the screen and the sensor, then only the glass is damaged, but the touchscreen remains intact. This design is found in almost all smartphones that cost more than $160-200, for example, in the iPhone. The second option is when there is an air gap. Then the sensor can be considered broken, but only its glass base is damaged, and the invisible sensor layer of conductors remains intact.

In the first case, the problem is eliminated by re-gluing the glass to a new one. You can’t do this on your own, as you need to disassemble the phone and heat it in special installation to remove broken glass from the screen. Not all services carry out such a procedure (here you need experienced master), but if you find a specialist, you can save money. The cost of repairs usually ranges from $15 to $100 (depending on the smartphone, as well as your country and city). The savings can be significant, because the original display for the same iPhone 6 with a replacement service can cost up to $150, and the glass itself can cost only $50. Therefore, if you break the glass on the screen of a new smartphone, but everything works, but the technician still talks about mandatory replacement for about $200 - you can try to find another technician who will only replace the broken glass. True, this is not always possible.

If the display has an air gap (in this case, when you press near a crack, the glass bends), then the sensor will have to be replaced. However, this is already easier; many more craftsmen are capable of doing normal repairs. Touchscreen replacement price for a very popular or budget smartphone– from 10 to 30 $, plus the cost of work (for example, in Ukraine – from 150 to 500 UAH, in Russia – from 1000 rubles). But for a rare model (for which spare parts are not mass produced) it may turn out to be twice as expensive.

What to do if you break the screen and it doesn’t work

If you break the screen and after that it either does not show (dark spots or areas filled with multi-colored patterns have appeared) or does not respond to your finger - everything is more complicated. For models without an air gap under the sensor, the entire display assembly will have to be replaced. The price of the issue depends on the model. For example, if you broke your iPhone 5S, you need to prepare to shell out about 30-50 dollars (the original screen is 1.5-2 times more expensive than a copy). On Xiaomi Redmi Note 2 or Meizu M3 repair costs from 25 to 60 dollars (also depends on whether the part is original or a copy), and on Samsung Galaxy S7 Edge – and all 300.

For smartphones with an air gap under the touchscreen (and this is the majority of Chinese-made devices, priced less than $120-130, and some models are more expensive), you can only replace the part that does not work. The price of the issue depends on the quality of the screen that happened to be broken and the complexity of the work. The replacement screen alone will cost between $25 and $50, and the sensor alone will cost slightly less. The popularity of the device also matters: for example, on the GSmart Mika M2, which cost about $100, the price of the assembled screen is about $50, and on the Xiaomi Redmi Note 3 Pro for $150 – from $20 (excluding the work of the technician).

Due to the strong variation in prices in different workshops and service centers If you break your phone, we recommend that you Google adequate prices before going to the repairman. You can do this simply by requesting something like “replacement/repair/price of screen [your smartphone model].” By comparing the offers of several services, you can determine where they are telling you a really favorable price for services, and where they are just trying to make good money on a girl who is not familiar with the intricacies of electronics repair and who accidentally broke her smartphone.
