How to hide a crack in a safety glass. How to remove scratches from a smartphone screen. What to do if your phone screen is cracked
Modern smartphone- a fragile thing, especially its screen. Tempered glass, which covers the displays for protection, is almost not afraid of scratches and light bumps somewhere in the middle. But from landings on a hard surface, and even if the smartphone hits the corner or edge of the screen, then it is 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 operational, and in some cases it stops responding to the finger.
There are several damage options, and what to do if the smartphone screen is broken depends on the type and scale of these damage. Therefore, we will try to figure out what's what, and draw up a further procedure. It should be noted right away: if certain parts of the display do not work, you do not need to try to make it respond to your fingers by increasing the pressure. After all, this way you can cut yourself on a chip or drive small fragments of glass into your skin.
What to do if the screen and sensor are working
If you break the smartphone screen, but it continues to show a picture, and the sensor reacts to 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, and the touchscreen remains intact. This design is found in almost all smartphones, more expensive 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 the conductors remains intact.
In the first case, the problem is eliminated by gluing the glass to a new one. You cannot do this on your own, since you need to disassemble the phone and heat it in a special installation in order to peel off the broken glass from the screen. Not all services carry out such a procedure (an experienced master is needed here), 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 replacement service can cost up to $ 150, and the glass itself - only $ 50. Therefore, if you break the glass on the screen of a new smartphone, but everything works, but the master still talks about the mandatory replacement for about $ 200 - you can try to find another master who will only change 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 changed. However, this is already easier, many more craftsmen are able to make repairs normally. The price of replacing the touchscreen 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 the screen is broken and it does not work
If you break the screen and after that it either does not show (dark spots or areas filled with colorful patterns appeared), or does not respond to your finger - everything is more complicated. For models without an air gap under the sensor, you will have to change the entire display assembly. The issue price depends on the model. For example, if you broke the iPhone 5S, you need to prepare to pay about 30-50 dollars (the original screen is 1.5-2 times more expensive than a copy). On the Xiaomi Redmi Note 2 or Meizu M3 repair costs from 25 to 60 dollars (also depends on whether the original spare part, or a copy), and Samsung Galaxy S7 Edge - and all 300.
In smartphones with an air gap under the touchscreen (and these are the majority of Chinese-made devices, priced less than $ 120-130, and some models are more expensive), you can replace only 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 be slightly cheaper. The popularity of the device also matters: for example, on the GSmart Mika M2, which cost about $ 100, the price of the complete screen is about $ 50, and on the Xiaomi Redmi Note 3 Pro for $ 150 - from $ 20 (excluding the work of the wizard).
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 master. This can be done simply by request such as "replacement / repair / price of the screen [your smartphone model]". By comparing the offers of several services, you can determine where you are called a really profitable cost of services, and where they just want to make good money on a girl who is not familiar with the intricacies of electronics repair who accidentally broke her smartphone.

Often, with careless handling of touch phones or tablets, 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 is broken.
1. Cracks appeared on the front. Can you replace it?
We are often mistaken in thinking that the front of the device and the sensor are two different parts. This is not true. The front end in touchscreen phones is itself touch glass(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 appear, not the correct reaction to touches or complete inoperability. 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 is working. Can I only change the sensor?
There are models that have a module where the touchscreen is "glued" to the display. It depends on the model of your device.
3. And there they change the sensor on the module!
There are times when a person, having come to the Workshop and having heard the cost of replacing the module, is outraged that in some Workshop everything is changed separately. Replacing the touchscreen separately from the display, when the module is installed to you, is quite possible and practiced, but there is a 100% guarantee that the procedure for removing your old, broken, touch glass will be successful, no master will give it, it is often damaged in the process of "peeling off" display and replacement of the entire module cannot be avoided. And the final cost of repair for replacing the sensor glass in the module is not significantly different than replacing the entire module.
Briefly about the main thing:
1. Having split the front panel into touch phone, You broke the sensor itself (touchscreen). Therefore, it is he 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 could render it unusable. So, it is advisable to replace it soon, while the phone is functional. Or at least extract all important information from such a device (photos, videos, contacts), if repairs are not planned in the future.
3. In models that have problems with the module (sensor together with the display), it is better to immediately replace the module.
4. Having saved on the quality of parts once, you run the risk of paying again soon, with a larger amount.

If your gadget does not have a protective glass, and you accidentally made a scratch by negligence. Don't despair, we have compiled a few life hacks on how to remove scratches from your phone or tablet screen. There are many effective tools for this, among which there are both the simplest and most widely available, and technologically complex ones.
Basic ways to remove 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 protective glasses camera lenses for mobile devices.
The choice of how to polish the screen or camera depends on the depth of the scratches and the total number of scratches.
Conventionally, the methods for removing scratches from the phone can be divided into 2 groups:
1 Chemical... Moreover, they can be additionally classified:
On those that involve the use of publicly available tools that almost every homeowner has:
- toothpaste;
- soda;
- vegetable oil.
And those that involve the acquisition of specialized (but at the same time widespread) chemical reagents and household chemicals, namely:
- baby powder (talcum powder);
- 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 the camera on the phone or from the screen of a mobile device using these methods.
Attention! You decide at your own peril and risk whether or not to use the methods described in the article. We cannot be held liable for possible damage to devices resulting from the use of the considered methods of cleaning displays and cameras of mobile devices.
Screen recovery with improvised means
You can remove minor scratches on a phone camera or gadget display using the most affordable means at home. It is expected that such products will have the least impact on the surface (can be removed effectively - small and small scratches).
It is about application:
- toothpaste;
- soda;
- vegetable oil.
We apply toothpaste
A small amount should be applied to the display or the protective glass of the camera lens using a cotton pad. Then in a circular motion (if scratches are observed over a large area) or back and forth movements with light pressure, you need to process the display, "erasing" the existing minor damage.
It is best to use the classic mint paste.
Fig. 1. We clean the device with paste.
Using baking soda
If toothpaste doesn't work, then another commonly available remedy is 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 rubber sponge or soft matter.
Important! Soda should be slightly moistened before use. Dry powder can damage the smartphone screen, fall asleep through the cracks in the case and interfere with the operation of the device.
Fig. 2. "Soda" effect.
The advantage of baking soda is that it acts on the surface of the screen a little harder than the paste, and therefore allows you to clean deeper scratches from the screen.
We use vegetable oil
Another remedy that is almost always at hand at home is ordinary vegetable oil. It does not have an abrasive effect like paste or soda, but it helps to effectively get rid of small scratches on the display glass.
It is necessary 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 overflow the oil - if it gets inside the device, it will be extremely difficult to remove it.
The hozmag will help
If removing scratches using the handy tools discussed above did not help, you may have to pay a visit to the household store to buy the following chemicals:
- baby powder or talcum powder;
- GOI pastes or its analogues;
- car polish;
- aluminum potassium sulfate.
We use 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 in that it involves a method of polishing, on the one hand, it is quite hard (since the powder contains solid particles), on the other hand, it allows avoiding the appearance of concomitant damage (since the particles of the powder are very small and there are no ways to cause a noticeable scratch).
Using GOI or Displex paste
These funds are specialized. They polish glass and plastic equally well. At the same time, in order to remove scratches from the smartphone camera, it is considered more effective to use GOI paste, and to clean the display - Displex.
Fig. 3. Displex - optimal for touch screens.
Application of car polishes
Products similar to GOI and Displex paste are car polishes. Among the popular brands of such products used to clean displays from scratches are Turtle Wax, 3M Scratch Removal. Car polishes are among the best for removing deep scratches from displays.
The mechanism of application of the above means - GOI pastes, Displex, polishes, is the same. Apply a small amount to a soft cloth, then polish the surface.
Note that the use of the above polishes may require the purchase of additional specialized products - for example, car wipes.
Uses of aluminum potassium sulfate and egg white
Among the exotic "chemical" methods of removing scratches from screens used by enthusiasts in the field of mobile electronics, the use of a mixture of these substances can be distinguished.
Fig. 4. The main thing is not to "sour" the screen.
Potassium aluminum sulfate (also referred to as "potassium alum") is an inorganic substance used in the leather industry as a tannin, in the textile industry, in the cosmetics industry. You can buy it at a chemical reagent store, including 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 up to 65 degrees. Then you need to dip a piece of microfiber in the solution, then dry it in the oven, which is heated to 150 degrees (while putting it on aluminum foil).
Then - cool the microfiber by dropping it into water, then leave it to dry for 2 days at room temperature.
The whole procedure must be repeated 3 times. Using a piece of cloth treated with the specified chemicals, rub the damaged surface of the mobile device. Remove minor scratches and damage.
The advantage of this method is that there is no need to use additional chemicals.
Let us now study how to remove scratches from a tablet or a 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 of removing damage from the display (note right away that they are not suitable for cleaning the camera). It is about the application:
- sandpaper;
- drill, grinder.
Remove scratches with sandpaper
The purpose of its application 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 handy to remove scratches in this way. But if you need to bring the old gadget into a more or less "marketable form" - the method will come in handy.
Fig. 4. Is the method tough, but fair?
We use a drill (with a felt roller), a sander (with special attachments)
The main function of such devices is to multiply the effect of using the "chemical" tools discussed above by automating polishing. If a user who has tried manual polishing has failed, and how to remove scratches, he does not know - 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 manual methods.
Summarize
Thus, there are many ways to "renovate" the screen of a mobile device from scratches. Let's try now to display the main features of their application in a small table.
| Method for removing scratches from a phone (mobile device) | Features (what to look for) |
|---|---|
| Polishing with paste | Mint paste is needed, preferably one color |
| Soda polishing | Moisten baking soda with water |
| Vegetable oil treatment | The main thing is not to overflow (otherwise the drops will get inside the device, and it will be extremely difficult to remove them) |
| Application 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 efficient way |
| Displex Paste Application | Optimized for cleaning displays |
| Application of car polishes | May require the use of a special tissue rubbing tool |
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 glasses of cameras on mobile gadgets.
At the same time, one must remember that prevention is always better than “cure”. Per mobile device need care. Careful storage of the device must be ensured. So, a good cover 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 affordable means can be used for this.
