Is it possible to change the touchscreen on your phone yourself? Self-replacement of the sensor. How to distinguish what is broken - the touchscreen (glass, touch glass) or the display How to replace the touch glass on a smartphone

Such a multifunctional device as a smartphone allows you not only to make calls, but also to take high-quality photographs. Thanks to additional programs, the device can become not only good entertainment, but also an indispensable assistant. Unfortunately, smartphones are impractical and any fall can cause a crack to appear on the screen. In order for the device to be functional again and look prestigious, the sensor must be replaced.

Why doesn't my smartphone work?

Before you decide to replace the glass on your phone, you need to understand the reasons why the screen of your mobile device stops working. The most common cause of failure is physical impact on the device.

The main reasons for direct impact include:

• Falling from height;
• Installing heavy objects on the phone;
• Placing a smartphone in the back pocket of pants (as a result of which the person simply sits on it).

The list of reasons goes on, but they are much less common than those described above. If such a situation occurs, the phone must be taken for repair so that specialists can change the glass.

In addition to physical damage, the screen may stop working after being exposed to water. There are cases when smartphone owners spill various kinds of liquids on their mobile devices. If a similar situation occurs with the phone, it must be dried as quickly as possible and taken for diagnostics. Otherwise, the oxidation process may begin.

It is important to note that after diagnostics it will be possible to understand what repairs the smartphone requires. It may be enough to change the screen. The worst thing is when microelements need to be replaced.

The least common defects that occur in smartphones are:

• The screen turns white. The reason is a damaged cable or a faulty controller;
• The picture is poorly displayed. In this case, the backlight has failed;
• A dark blue screen is displayed. The problem is related to a broken display or controller;
• The image periodically disappears and the picture is distorted. The reason is due to a broken cable;
• Ripple appears. The controller or the display itself is faulty.

In most cases, only replacing the phone screen will save the situation. Even if the reason is obvious, it is best to take the mobile device to a service center for diagnostics.

It is important to remember that broken glass cannot be repaired, it can only be replaced. So, in what cases will you need to replace the touch screen:

• A crack or a whole “web” has appeared on the surface of the glass;
• The screen stopped responding to touch;
• The phone freezes when ;
• The mobile phone executes incorrect commands after touching the screen.

Remember that a smartphone screen consists of several thin layers. If one of them is violated, the sensor stops responding correctly to commands. Sometimes it is enough to replace only the glass. In this case, you will save a decent amount.

When the image begins to blur or is only partially visible, more advanced repairs will be required. In this case, you will have to replace the display, and this already costs other money.

If cracks appear, the glass can be replaced on your own. If you need to replace the display, it is strictly not recommended to do it at home. Screen replacement should only be performed at a service center using original parts.

Service cost

Repairing a smartphone is not a cheap pleasure. Therefore, it is recommended to find a service center where diagnostics are performed free of charge. Why pay more if you can save. After diagnostics, specialists can accurately determine whether the glass needs to be replaced, or whether the entire display will have to be replaced.

Replacing the glass will cost significantly less than installing a new display. Service centers charge from 1,000 to 3,000 rubles for such a service. It all depends on .

As for directly replacing the display, such a service will cost half the price of the smartphone. To save money, you can compare the prices of several service centers and choose the more profitable one.

It may take several days to change the display. As for glass replacement, the procedure takes only a few hours. At the same time, do not forget about the time for diagnosis. You should expect the phone to be repaired within 2 days. Of course, you can pay for urgency and then the work will be completed within 2-3 hours.

Replacing the screen at home

There are times when service centers charge too much money for glass or display replacement. To save money, you can do all the repairs yourself. It is important to note that such a procedure should only be undertaken if you are completely confident in your abilities.

First of all, it is necessary to make a diagnosis. Service centers will help with this. It is recommended to choose a center where services can be cheaper or completely free. After this, you will need to purchase all the necessary parts. To save money, it is better to make purchases in online stores, but it is worth considering that the goods will not arrive in one day.

To replace the screen you will need the following tools:

• Set of special screwdrivers;
• Soldering iron;
• Tweezers.

You may not need a soldering iron. It all depends on the phone model. Before starting the procedure, you must remove the battery and SIM card from the mobile device. Then you should start parsing. To avoid any difficulties, it is recommended to find video instructions on the Internet. It is important that the number of bolts unscrewed is equal to the number of bolts tightened. If even one part is lost, the phone will no longer work as before.

Remember that the entire procedure is performed at your own peril and risk. There is no guarantee that everything will be done correctly. Therefore, you need to compare how much it costs to replace the screen on your phone and buy a new mobile device.

If you manage to repair the device yourself, you will save a decent amount. Before starting the procedure, it is recommended to practice on an old mobile phone that you don’t mind damaging.

Conclusion

Before sending your phone in for repair, you need to find out how much it costs to replace the glass or screen. It is recommended to compare several service centers and then choose the one that is cheaper and more reliable. Don't forget that cheap is not always good. You need to read the reviews of the service center. As for replacing the screen yourself, you should not do this, although it is possible to save a decent amount of money.

If the screen of your Samsung Galaxy phone has stopped responding to touches, or the response is delayed, you need to replace the Samsung Galaxy touchscreen. Service center engineers will diagnose the device and determine the timing and cost of upcoming work. Replacing the touchscreen occurs in stages:

• Diagnosis of the cause of the malfunction;
• Samsung Galaxy disassembly;
• Replacing the touchscreen;
• Guarantees.

Owners of Samsung smartphones often encounter damage to the touch screen glass. Problems in the operation of the touchscreen are manifested in the following symptoms:

• White spots appear on the screen;
• the sensor does not respond correctly to user touches or does not work;
• after calibration, the new settings are lost and the glass again works with errors.

If the Samsung Galaxy touchscreen malfunctions, it is difficult for the smartphone owner to use the faulty device. Therefore, many turn to a service center - self-repair requires skills and specialized equipment when it comes to mechanical breakdowns (for example, when the sensor cracked after a fall). If the phablet malfunctions due to software problems, the prospects for troubleshooting depend entirely on the user’s computer literacy. Responsibility for attempts to independently restore the device depends entirely on the user’s decision - no one can guarantee that unauthorized intervention will be carried out efficiently, without complications and will give the desired result.

Causes of touchscreen malfunction on Samsung Galaxy smartphones

The factors leading to the failure of the touchscreen of a Samsung Galaxy mobile phone are varied. These include:

• mechanical damage to the touch glass - chips, cracks;
• malfunction of the cable coming from the motherboard;
• flooding your Samsung Galaxy smartphone with liquid;
• software errors;
• Damage to sectors due to which part of the sensor does not function.

It happens that when the phone falls, the entire display breaks. In this case, to repair the smartphone, the entire screen unit is replaced.

Replacing the touchscreen sensor of a Samsung Galaxy phone

Users will be able to replace a faulty touchscreen without wasting time – the customer service center provides free delivery of equipment before and after repair. To order a courier, call the call center and operators who work around the clock will fill out a request. SC branches operate in various cities of Russia: Moscow, Yekaterinburg, Nizhny Novgorod, St. Petersburg, Krasnodar and others. For a complete list of cities where service center services are available, see the website. Couriers travel up to eighty kilometers from the service.

To change the touch glass of a Samsung Galaxy phone, technicians from the service center’s engineering department use specialized equipment - replacement involves heating the part to soften the adhesive layer and make it easier to remove the broken touchscreen. Preliminary diagnostics are carried out to identify additional device failures and determine the cost of performing the service. Diagnostics do not increase the replacement price and are provided free of charge.

When the specialist has determined the scope of work, the manager informs the customer of the diagnostic results and announces how much it costs to replace a non-functional touch glass. When consent for repairs is received from the customer, the service engineer replaces the faulty touchscreen. Spare parts used for restoration are double checked. The first time a new component is tested by a technician before installation. The second check is carried out in the quality control department, where the phone goes before being returned to the customer. After replacement with a refurbished phone, the warranty of the service center is valid. Its duration depends on the installed spare parts and the reasons for contacting the service center. In addition, service center clients can order repairs under an accelerated program, when the device is restored out of turn. In this case, when filling out an application, you need to notify the operator of your desire to repair your Samsung Galaxy urgently.

Touchscreen replacement guarantees

Replacing a touchscreen is a complex operation that involves delicate work and requires concentration, skills, tools and the ability to handle them. Samsung service center engineers will replace the damaged component and guarantee the proper operation of the phone. The warranty period covering the work of a new part is up to three years.

In order to repair your tablet, you just need to take it to the nearest service center that specializes in repairing such devices. Experienced employees will quickly replace the damaged part.

However, the budget does not always allow you to use the services of specialists or it is difficult to find a workshop near your home. Then you can repair the tablet sensor yourself. In this case, a number of simple but mandatory rules must be observed.

Preparing to replace the touchscreen on your tablet.

It is important to remember that during repairs it is strictly forbidden to use metal aids that can cause mechanical damage to the housing.

In order to change the sensor or touchscreen on the tablet, you need to prepare the tools necessary for minor repairs.

Tools for disassembling phones and tablets can be purchased at specialized or hardware stores. Or you can order it together with the touchscreen on our Terabyte Market website.

Required tools:

• stationery knife
• any flat plastic object: pick, plastic card, drawing template
• a regular hairdryer used to dry hair
• tweezers
• screwdriver (usually Phillips)
• soft lint-free cloth

We disassemble the tablet and change the touchscreen

• First, use a screwdriver to unscrew the bolts (if any) located in the end parts of the gadget.
• To disconnect the cover from the rest of the body, use a plastic card or similar plastic object. We use it to pry the body a little and guide the plastic along the perimeter.

• The device cover and the body are connected to each other using a cable. It must not be pulled out, otherwise you will disrupt the entire operation of the device. The cable is pulled out after you open the connector:

find the latch on the side of the cable and carefully pry it off;

Pull out the cable.

Find out the model of the touchscreen on the tablet:

• Write it down on a separate piece of paper number of pins and markings on the cable.
• Selecting a touch glass model suitable for your device

In the browser, through a search engine, we look for a suitable online store and communicate with a sales consultant or manager. Our staff will help you choose a touchscreen for a specific gadget model. After purchase, you should check the sensor for damage.

Found and bought Taskrin for your tablet?

You can continue to repair and replace the touch screen yourself.

We completely disassemble the tablet screen

1) Remove the cracked screen; to do this, heat the case with a hairdryer.

2) Now disconnect the screen from the body. To do this, insert a stationery knife into the double-sided tape or take our old credit card, moving carefully along the perimeter of the device, peel off the glass.

3) The touchscreen has been successfully removed, now we use a utility knife or plastic tweezers to remove the small remaining pieces of tape.

4) Using a napkin or soft lint-free cloth, remove the remaining small glass crumbs from the screen.

IMPORTANT!!! : Before peeling off the protective films from the new touchscreen, check its functionality by connecting the cable of the new touchscreen instead of the old one! Turn on the tablet and check how the new touchscreen works. If it does not work, then feel free to change the touchscreen in a store bought one. If you remove the films and stickers, they won’t replace it for you!

5) Prepare the purchased sensor for installation: remove the protective films and paper stickers.

If you bought a touchscreen or touch glass without self-adhesive tape, then we recommend this product to you:

Scotch tape 3M 300LSE double-sided transparent original for repairing tablets and phones.

6) We try the touch screen on the gadget, place the touch screen on the frame.

7) Gently stroke the frame with the installed sensor with your fingers.

We assemble and configure the repaired tablet with our own hands.

• We assemble the device in reverse order.
• To prevent scratches from appearing on the screen of the gadget, we will glue a protective film on it. Some touchscreens are sold with a factory film.

How much will it cost to replace the touchscreen on a tablet?

Parts for new models are much more expensive than for older gadgets. The average price of a touch screen is 800 - 2,000 rubles. In addition, many large manufacturers sell sensors in a set with a matrix, called a module (touchscreen + matrix). The cost of a matrix for a tablet varies from 1,500 rubles. Therefore, the price of such a kit is from 2,500 (the price of the touchscreen + the price of the matrix). In service centers, for replacing a matrix or touchscreen they charge from 500 rubles to 2,000, depending on the complexity of the work.

The touch screen of a tablet consists of two parts: a touchscreen and a matrix. In most cases, the screen breaks, but the matrix remains intact. Therefore, even if the glass is cracked and the sensor is working, you should replace the screen as soon as possible. Don't delay repairing your gadget. Otherwise, you will have to spend money on not one part, but two. This, of course, will cost more.

All repair work on the gadget must be carried out very carefully so as not to completely damage the device.

Gluing the sensor takes a lot of time and effort. Before you start gluing the screen, you should make sure it is in good condition.

How to prevent your tablet's touch screen from getting damaged?

Protect the gadget from sudden temperature changes at which the glass can crack.

Purchase and stick a special protective film on the screen.

Do not drop the gadget.

Do not leave the device on a sofa or chair because you may accidentally sit on it.

Buy a hard case for your gadget.

With the advent of smartphones, the word “touchscreen” is on everyone’s lips. Touchscreen – from English touch screen. Touch – touch, touch, screen – screen. Therefore, in literal translation: a touchscreen is a screen that is touched.

In our article we will change the car of a Chinese phone

Why did I decide that my touchscreen had burst? What if the display? To find out, read the beginning of this article.

Types of touchscreens

Touchscreens come in different types. Mainly resistive And capacitive. Capacitive touchscreens come with multi-touch technology and simple ones with one touch, let’s call it mono-touch. A striking representative of multi-touch is Apple phones and tablets. For example, with two fingers we can zoom in or out on a picture

This doesn’t work on old Chinese and simple cheap phones, because they use resistive touchscreen The resistive tank consists of a glass substrate and a thin film. There is a coating on the glass and film that has Resistance. The glass substrate and the film are separated from each other and are not connected anywhere.

In the figure below, we see the glass substrate (bottom) and film (top).

As soon as we poke our finger into the car, we push the film and it closes with the glass substrate. The work algorithm takes place in two teams. First, the controller supplies voltage, mainly 5 Volts, to Ux1 and Ux2. Uy3 and Uy4 at this time have zero potential, that is, the ground. In this way, the X coordinate is determined. Then, immediately after the first command, the second command occurs: 5 Volts are supplied to Uy3 and Uy4, and Ux1 and Ux2 become ground. Thus, the Y coordinate is determined. The microcontroller analyzes all these voltages and displays the location of the pressed point, which in turn, presses a button on the phone.

How distinguish Resistive and capacitive touchscreen?

Firstly, if there is multi-touch technology, then the touchscreen is capacitive in any case.

Secondly, The capacitive touch only responds to pressure with a bare finger. You can’t press anything here with a fingernail or a stick, unlike with a resistive touchpad. The resistive touchscreen can be pressed even with a match.

Third, when you press the resistive touchscreen, you feel the film being pressed literally half a millimeter at the point of pressing. When you press the capacitive touch, nothing is pressed anywhere except your finger.

Chinese cars generally have 4 outputs: X+, X-, Y+ and Y- If you see any microcircuit on the touchscreen cable, keep in mind that this is already a touchscreen with multi-touch technology.

Changing the resistive touchscreen on a Chinese phone

Okay, let's get to the point. The first step is to carefully unsolder the broken touchscreen. Do not bend the display cable all the way, otherwise the contacts will bend at the very base of the solder and break the cable.

Lubricate with a drop of gel flux RMA-223 or FluxPlus

and solder the car with a soldering iron

Now you need to separate the broken touchscreen from the display. He sits on glue. To soften the glue, we will need the help of a hair dryer. Gently blow along the perimeter of the touchscreen with a hairdryer at a temperature of 150-200 C° for a minute.

Then we separate it with some thin object

And here is the culprit of our repair, we throw it straight into the trash bin

Mostly new touchscreens are sold without an adhesive base. This also applies to any other touchscreens. Many people ask the question: “How to glue the touchscreen?” Some people even manage to use super glue. You should not do this under any circumstances! Almost all repairmen have been using double-sided tape for a long time. It is sold in all hardware stores.

Currently, the Chinese have also released a special glue for touchscreens.

You can watch it using this link.

If you still don’t have it, then all you have to do is run to the hardware store and glue it with double-sided tape.

Cut the tape as thin as possible and stick it around the perimeter of the car

Then we peel off the tape and get a car ready for installation on the display

We install this whole thing on the display

It also happens that sometimes the car does not match the paths. What to do in this case?

Well, let's throw wires. In telephones, very convenient wiring can be obtained from the telephone headset or its speaker, which has served its age

We throw wires and check the phone. Don’t forget to clean the whole thing with Flux-Off to remove any remaining flux.

By the way, touchscreens for Chinese phones can be selected from a completely different model. The main thing is that the dimensions of the touchscreen match. Sometimes there is such a jamb that it seems to be sealed, all the chicks and puffs, but suddenly it turns out that when you press in one place of the display, a button in another place is triggered. Basically this is the so-called “mirror” jamb. In this case, we swap the touchscreen pins and achieve normal, correct pressing. As soon as the car is soldered, it is advisable to immediately calibrate the display. We look in the phone settings and calibrate.

Modern technologies being introduced everywhere and in everything significantly simplify our lives. The “sensory innovation” also affected mobile devices—phones. Today, most of these electronics are equipped with Touch Screen panels, through which the user can interact with a specific communication device with particular ease. But, as you know, there is no smoke without fire... At some unfortunate moment, your favorite smartphone becomes “unresponsive”, not reacting to the touch of your fingers. However, replacing the touchscreen - as an inevitable process in repairing this type of fault - will help you regain lost control over the device. To learn how to do this yourself and why in some cases you still cannot do without the help of specialists, read this article.

About mobile fragility, optical illusion and the obligatory repair process

It often happens that when the phone falls, the touch panel breaks, but retains its “workable” qualities. Under such unfavorable circumstances, the device only loses its aesthetics. Nevertheless, it is difficult to disagree with the fact that broken lines of cracked glass or plastic spreading across the screen are, in general, an unpleasant sight. As you understand, in order to restore the former beauty and attractiveness of a “lost face” device, you will need to replace the touchscreen. It is necessary to reinstall the damaged part for one more reason: the display located under the touch panel becomes the most vulnerable. Since nothing else prevents the penetration of dust and moisture. And even with a slight mechanical impact on the screen - be it careless pressing, pinching, or some previously uncritical pressure (a tight pocket, for example) - there is a high risk that the matrix will not withstand it and, as they say, will float.

A little about “Alas...”

Let's make a reservation right away: it is simply unrealistic to change the touch glass of some modifications of mobile phones at home. Sometimes the manufacturer uses, so to speak, sandwich technology, firmly gluing the display and touch module together. Of course, such a “tandem” has a lot of advantages, but the main disadvantage is one: replacing the touchscreen (glued to the LCD) is impossible without the use of special equipment. Don’t be deceived by all those who have seen or read on the Internet about a miracle method that guarantees 100% success in the process of separating the screen from the “touch” - these are all stories or isolated cases of a successfully conducted experiment.

So, before embarking on a “touchscreen replacement” restoration project, make sure that your mobile device is not a “successor” of OGS (full lamination) technology!

How to change the Touch Screen module if it is removable?

First of all, you need to know exactly how your phone is disassembled. In the case when you dismantle the body parts of the smartphone, so to speak, blindly, you are unlikely to be able to avoid various breakdowns in the future. Without a special tool, some models simply cannot be disassembled. For example, to remove the back cover of an iPhone you need a pentalobe screwdriver. Some smartphones have glued casings, while others are oversaturated with various hidden fasteners. Well, still others even combine all sorts of structural tricks. In general, you simply cannot do without a disassembly manual.

General principles and fundamental rules: replacing a Samsung touchscreen

Only relatively recent modifications of the brand mentioned in the title are equipped with “hard-to-separate” screen modules. Other phones, such as the S5320 and others like it, are easily amenable to the touchscreen reinstallation process. Although, to be more precise, a plastic touchscreen, because the main material from which it is made is polymer. Well, let's take a look at the generally accepted universal algorithm of actions when replacing a removable Touch Screen element.

• Purchase only original quality sensor modules.
• Use the service manual to disassemble your device.
• Take your time and be patient (psychology in microelectronics is an important component of a successful result).
• Before picking or pulling anything, make sure that all the bolts are unscrewed and that any sticker does not hide a “forgotten” screw.
• Be careful not to break internal cables and connectors.
• Avoid any movement or gaps when positioning the touch screen; its edges should fit snugly against the base of the phone.

In general, be careful and consistent. Do not hurry! Glued - heat and release without jerking, twisted - unscrew and carefully lift. The main thing is that you should not have any “extra” details.

Solution for “glued” Touch Screen panels

When a Lenovo touchscreen is replaced (and models of this brand have recently been mainly equipped with “sandwich” display modules), specialized equipment is used - separators, or, as they are also called, preheaters. Naturally, a machine that is far from cheap is the prerogative of service centers and professional workshops. However, if you turn to specialists, then reasonable savings (after all, the screen is working) will ultimately still be insignificant. Therefore, it is more advisable to purchase an original display module and install it yourself.

It is worth noting that for some smartphone owners the price of the part may seem a little expensive. However, this is the only “painless” method to get rid of the problem we are highlighting on your own. Don’t try (oh brave ones of this world!) to repeat those stupid experiments using red-hot spirals and irons, which are abundantly available on the Internet. It’s better to let the screen remain intact, so to speak, for the future, than to crush or melt it when you carry out its “unconventional” replacement.

Sony's touchscreen couldn't be more reliable: a practical answer to an advertiser

Of course, this is a rather controversial statement, but it is not without meaning and there are provable arguments too. However, let's be realistic and, as an example, consider a step-by-step plan for implementing the repair process, which can be titled “Installing a new display module on a phone from a legendary brand with your own hands”:

• As a rule, the back panel of the smartphone is attached using an adhesive base.
• Use a regular household hair dryer - walk along the edges of the protective cover (the back of the device) and gently lift one of the edges. Pull the blade of the tool around the entire perimeter of the body.
• Dismantle all internal components of the phone, not forgetting that accuracy in actions is the key to the success of the enterprise!
• The display module is also glued to the case base - warm it up and carefully remove it.

Once you install the new screen, along with the original touchpad, and successfully assemble your favorite phone, you will have something to be proud of!

As an encouraging ending

Replacing the Xperia or iPhone touchscreen is carried out according to the same scenarios as described above. If you don’t want to take risks and feel somewhat insecure with a screwdriver in your hands, contact a specialized workshop, and they will definitely help you. Well, I would like to wish inquisitive practitioners success in engineering research. All the best to you, and may your phone always be “mega-clickable”!
