Often, with careless handling of touchscreen phones or tablets, cracks or so-called "webs" 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 crashed.
1. Cracks appeared on the front. Can it be replaced?
Often we are mistaken in thinking that the front of the device and the sensor are two different parts. This is not true. The front part in 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 pressing, an incorrect reaction to touch, 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 a film), then you will have to change the touchscreen (sensor),.
2. The sensor is broken, but the display works. Can I just 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 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 to you, is quite possible and practiced, but not a single master will give a 100% guarantee that the procedure for removing your old, broken, touch glass will be successful, often in the process of "peeling off" it is damaged, bursts display and replacement of the entire module cannot be avoided. And the final cost of repair for replacing the sensor glass in the module does not differ significantly from replacing the entire module.
Briefly about the main:
1. By breaking the front panel on a touchscreen 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 the appearance of cracks 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 in the near future, while the phone is operational. Or at least extract all important information (photos, videos, contacts) from such a device 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.
Quite recently, one unpleasant situation happened to me - my old man Acer Liquid Mini completely stopped responding to any commands and touches. This, of course, upset me, to put it mildly, however, before taking it to the service center and getting ready to part with a couple of extra thousand rubles, I decided to “scroll” the Internet and find out - or maybe somehow I will be able to solve this issue on my own, without spending extra money. And imagine how happy I was when I finally found a way out.
As it turned out later, it was not the screen itself that failed, but only part of it - the touchscreen, which is responsible for entering information, reacting to finger presses. Therefore, changing the entire screen along with the matrix was not a persistent necessity, it was only necessary to “screw” a new touch!
And, having tried a little, I performed this “surgical” operation on my own, keeping within a quite acceptable amount - 1,500 rubles, which is exactly how much a new touchscreen in an online store cost. For comparison, in any city service center, not to mention official representative offices, such repairs will be done for no less than 5,000 rubles. The savings are really significant.
So is there any reason to try to replace the touch yourself? Unfortunately, I got carried away with the process and the photo of the report, as such, did not work out, but I tried to describe everything in as much detail as possible with words.
To begin with, it is worth figuring out what exactly needs to be repaired or changed. For any problems with the screen, there is a very simple instruction.
- We have
- Broken/intact glass
- The image is still there
Diagnosis: it is necessary to change the touch screen itself.
- We have
- broken glass
- Picture is
Diagnosis: The protective glass is to be replaced along with the touchscreen. Unfortunately, replacing only the glass will not work, because on any communicator glass and touchscreen always go together.
- We have
- Intact glass
- Smart responds to all touches
Diagnosis: In this situation, it is necessary to change the display, which is responsible for adequate display of the picture.
- We have
- Broken / whole glass
- Smart does not respond to any touch
- There is no image or it is severely distorted
Diagnosis: This is the most complete set of troubles that can happen with a smartphone. In this case, you need to change both the display and the touchscreen along with the protective glass.
Since we don’t advise anyone to deal with replacing the matrix itself, such a case is intended only for professionals who have considerable experience in this, since the probability of an error by beginners during this operation is simply catastrophically high, we will only tell you how to replace the touchscreen in at home with your own hands. With the proper skill, anyone can handle it.
Naturally, we warn you before that - wrong actions can cause serious damage to your smartphone, therefore, if you are not sure, it is better to spend a little more money and even replace the touchscreen in a service center. If you have direct hands and you decide to do everything yourself - the responsibility is on you.
To begin with, it is worth understanding what the touchscreen itself is. Someone unknowingly calls all elements of the screen with this word, however, in fact, only its upper part is a touchscreen - namely, a touch film applied to the glass under which the display is located.
In order to replace the touchscreen on a smartphone, you will need the following tools:
- Soldering iron with the necessary materials - solder and flux (preferably a soldering station)
- A blade or a very sharp knife (a blade is preferable anyway)
Moreover, a soldering iron and related materials will be needed only if you are dealing with a touchscreen that is connected to the matrix not by the usual click of the cable into the board connector, but by soldering.
If the screen is connected by soldering, first you need to unsolder the old touch from the inside of the screen. The main thing is to set the soldering iron to a moderate temperature and act quickly so as not to overheat the place of soldering, thus damaging the matrix.
The next step is the first step for screens without soldering, and the second for those that require a soldering iron.

Here we need to disconnect the touchscreen from the matrix. To do this, take a sharp blade and cut the glass as carefully as possible along with the touch. Make sure that during this process you do not touch the matrix crystals, otherwise damage to it cannot be avoided, and after that you will have to buy a new display!
A little tip: to make this process easier, you can put your smartphone under a regular table lamp and wait a bit. Light heat will soften the adhesive and make it easier to cut.
Next, remove the protective film from the brand new touchscreen and carefully install it in place. Then, depending on the screen, we either solder the touchscreen cable to the matrix, or simply snap the connection between them (so that you don’t climb under the “hood” again, make sure that you fasten the touch to the matrix with the highest quality).
The most important thing in the whole process is to cut the touch screen very carefully, because it can easily crack and damage the matrix, and also carefully handle the touch screen cable, because it is very easy to tear, and then you have to spend money on a new touch again.
That's it, the work is done! Congratulations, you can enjoy your new working smartphone!

For those who do not want to change the touchscreen on their own, you can simply buy it and take it along with your smart phone to a service center. So at least the extra charge can be avoided, and you will pay only for the work.
The touchscreen is one of the most vulnerable components of a mobile device. An accidental drop, even from a small height, can cause the screen to become cracked, scratched, and unresponsive to touch. The most obvious solution, in this case, is to contact the master at the service center.
However, the cost of repair, depending on the phone model, can vary from 300 to 2000 rubles. The question arises: is it possible to replace the touchscreen on the phone with your own hands? And most importantly - will such a repair come out cheaper? Given that in online stores, for example, on Aliexpress, a smartphone screen can be taken for little money - about 200-300 rubles - self-repair of a cracked touchscreen becomes a very real alternative.
It is only necessary to be aware that any independent intervention in the filling of the smartphone can lead to even more damage to the gadget. Therefore, it is important to strictly follow the instructions and correctly evaluate your repair abilities.
What is a smartphone touchscreen
Before you replace the touchscreen on your phone yourself, you should clearly understand what kind of component it is and what, in general, the screen of a mobile device consists of. This knowledge will help with repairs when you need to disassemble the smartphone into parts.
In a modern smartphone, the display is a kind of sandwich - several interconnected layers:
Matrix - a panel consisting of liquid crystals or LEDs, which is connected to the board using a cable.
A touchscreen is a transparent touch surface made of glass or plastic. From the inside, a layer of conductive material is applied to the touchscreen. On the outside, there is sometimes a special oleophobic coating that prevents the appearance of greasy spots on the surface of the touchscreen.
Protective glass - some smartphone models are equipped with a special shockproof tempered glass panel that protects the touchscreen from external damage.
If the smartphone is not protected by glass, the main burden falls on the touchscreen. Moreover, it is not necessary to drop the smartphone to damage the fragile panel. Many users carry the gadget without a case in their pocket along with keys and coins. As a result, the display of the device quickly loses its presentation.
Many modern flagships are equipped with the so-called OGS display. In this case, the touchscreen and the matrix are, in fact, a single panel. Repair of such displays is recommended only in service centers, as the craftsmen use special tools such as a heating stand, photopolymer glue, an ultraviolet lamp, and so on.
How to replace touchscreen on phone
At home and with available tools, it is quite possible to replace the touchscreen of a smartphone if there is an air gap between the matrix and the sensor.
What you need to replace the touchscreen:
Glue B-7000 (costs about 100-150 rubles)
Thin rubber gloves (you can take medical ones)
New touch panel
Curly screwdrivers
Guitar pick, plastic card (business card) or thin spatula
Silicone suction cup (can be purchased at a hardware store or can be disassembled from a bathroom hanger that attaches to the wall)
Stationery knife
Now you can start replacing the touchscreen:
Remove the back cover of your smartphone.
Remove the battery.
Using a screwdriver, remove all screws around the perimeter of the case.
Insert a pick between the case mount and pry gently. It is important not to push the pick too deep, so as not to damage the internal components of the gadget.
Using a hair dryer, you need to heat up the glue that connects the touchscreen to the matrix. It is recommended to heat up to a temperature of 70-80 degrees. Some experts also point out that the gadget can be wrapped in a towel and put on a hot steam heating battery. At this step, it is important not to overheat the screen and other components of the smartphone.
After the glue has warmed up, you can separate the touchscreen from the matrix. For this, a suction cup is used. Attach it to the display, press and separate the touchscreen. Also, softened glue can be further trimmed with a clerical knife. Here it is important to ensure that the blade does not scratch the touch panel and matrix.
Clean the body of any adhesive residue.
Apply a thin layer of adhesive and install a new touchscreen.
Press lightly and remove excess adhesive.
Assemble all body parts and tighten with bolts.
How to never face a touchscreen replacement
As you can see from our instructions, replacing a touchscreen on a phone is a rather painstaking and responsible task. One wrong move - and you will have to repair the whole phone. If the user is not confident in his technical knowledge, and besides, for various reasons, he does not like smartphone cases, it is best to take care of purchasing such a gadget in advance, which will help minimize the risk of touchscreen breakage.
The most obvious option is a smartphone with impact-resistant glass installed. True, many users are sure that secure mobile devices are produced only among top-end expensive flagships. Fortunately for users who really evaluate their budget, it is really possible to find a powerful and productive smartphone with a protective glass at an affordable price in the modern mobile market.
And here we recommend paying close attention to the British company Fly, which since 2003 has consistently maintained a reputation as a supplier of reliable, modern and affordable phones. The spring-summer season of 2017 was especially significant for the brand, as during this period users were able to appreciate Fly's incredibly elegant technical solutions: smartphones that look and work like frank representatives of the middle price segment, while having extremely affordable price tags.
We will talk about the models Fly Cirrus 13 and Fly Selfie 1.
Both smartphones are equipped with extra strong glasses that protect the touchscreen from chips, scratches and cracks. Fly Cirrus 13 is equipped with DragonTrail glass, and Fly Selfie 1 received a Panda Glass panel of increased strength. By the way, numerous tests show that DragonTrail glass is 6 times stronger than Gorilla Glass silicate glass. An example of one of the tests can be seen in this video:
It is also important to note that in all models, clear and contrasting 2.5D IPS displays are made using Full Lamination technology. In this case, the air gap between the layers of the display is removed, so that the user feels literally every detail of the image at his fingertips.
As mentioned above, one of the main principles of the Fly company is availability while meeting modern technological requirements. Fly Cirrus 13 and Fly Selfie 1 absolutely correspond to this position. Metal cases, fingerprint scanners, powerful 4-core processors, LTE modules, high-quality photo modules, capacious lithium-polymer batteries - at first glance it seems that with such components it is hardly worth waiting for a budget price tag. However, the cost of Fly Cirrus 13 is only 8,490 rubles, and Fly Selfie 1 sharpened for selfie shooting is 8,990 rubles!
Now you know how to replace the touchscreen on a smartphone. We remind you once again that any independent intervention in the filling of the phone, even for self-repair, threatens with even more serious damage. It is much more reliable to purchase an affordable, powerful and secure smartphone in advance, and in case of a breakdown, contact specialized service centers.
