Electronic components can break if used carelessly. If a part of the touch screen on the phone does not work, this can be caused by both the temperature mode of use and mechanical damage.
Correct diagnostics will help to repair the screen of a smartphone or tablet that does not respond to touch. Sometimes simple cleaning combined with disassembling the case helps. However, if, after all the user's actions, the device does not turn on, it will have to be carried to the service, and this can lead to additional costs.
Breakdown reasons
There are the following reasons why a part of the screen does not work:
- Oxidation of the contacts due to the ingress of condensation. Moisture trapped inside the device can lead to complete or partial loss of functionality. Oxidized contacts stop responding to processor commands and transmit them to the screen. To eliminate the consequences of liquid ingress, it is necessary to disassemble the device and clean the internal components. To do this, you can use rubbing alcohol on a cotton swab or swab. After this procedure, the phone should turn on in normal mode.
- Cracks on the surface of the screen. Due to micro-damage to the sensor, it stops responding to pressing. Such damage occurs due to falls or impacts on the screen. You can identify cracks in the display by carefully examining its surface. If part of the touchscreen is covered with cracks, then it is possible to return it to work using the device.
- Disabling touchscreen contacts as a result of displacement. This usually results in the lower or upper half of the screen not working. To diagnose contact misalignment, you need to disassemble the device and see if the visual order of symmetry of the components is broken. If you see misaligned contacts, you can try to correct them with tweezers. In addition, some of the elements are fixed with glue, which can melt at high temperatures and displace the contact. In order for the upper part to return to its place, you need to heat the mount with a hair dryer and return the component to its original position.
Features of the operation of electronic devices
In addition to the listed breakdowns, electronic devices may malfunction due to the peculiarities of the internal architecture. The limitation of the size of the components affects their power reduction if the tablet screen does not respond to touch - this may be due to the overload of the device with a large number of resource-intensive applications. For prevention, you need to start the task manager. Find out what is loading the central processor of the device and disable unnecessary applications.
Electronic devices have increased screen sensor sensitivity. The situation when the screen of a tablet or phone does not work may be associated with trivial pollution. Grease and dust sticking to the surface makes the tablet unresponsive to touch.
If the screen does not work on the tablet, the best solution would be to take it to a service center for diagnostics. Most models have a very long warranty, which will allow you to replace the device with another device without defects or get your money back at no additional cost. If the case is not guaranteed, perhaps you just need to buy a new gadget and then treat it more carefully.
Video review of the causes of screen breakdowns
If you notice that the sensor is not working on your tablet, be sure to read our instructions. We will try to help you solve this problem.
Technology and electronics greatly simplify our life every day. We, for the most part, will not be able to live without tablets and phones, because almost all spheres of our life depend on them: both social and economic, even sometimes political. Therefore, when we find that the sensor on the device does not work, it becomes a very big problem, because there are practically no buttons for them, everything is controlled by the sensor.
Unfortunately, the breakage can sometimes be invisible to the naked eye. Sensor shutdown is not always caused by ingress of water / dust or rough handling.
So, what are the main reasons why the sensor on the tablet stops working:
1. Liquid or contamination in the sensor. This also includes fingerprints on the screen, which can lead to a decrease or loss of touchscreen sensitivity.
In the first case, immediately after detecting the ingress of liquid inside the tablet, turn it off and, if possible, disassemble, clean and let it dry. If stains appear on the screen that cannot be wiped off, then the screen should be replaced and all internal components of the device should be cleaned to prevent oxidation.
2. Mechanical damage to the tablet (drops, shocks) or strong temperature changes. Even if the screen of the device does not have any visible defects, and the sensor still does not respond to touch, then, most likely, the touchscreen will have to be replaced. If the sensor stops working due to exposure to too low or high temperatures, then the best solution is to wait, the fault should go away on its own.
3. Damage or loosening of the loop, which is responsible for the connection to the sensor coating.
4. Failure in the software (software) of the tablet.
The simplest thing that can be done in this situation is to restart the tablet and let it rest for a while, since the gadget could freeze due to a large number of running applications, which led to the sensor malfunctioning. It is worth considering not only open applications, but also applications that are in the background, since they also load RAM.
If a simple restart did not help and the sensor on the tablet still does not work, then you can try to check it for any viruses and remove all unnecessary or questionable applications. After these operations, you need to reboot the device.
The next way to solve the problem with a non-working sensor is to reset the tablet to factory settings. Please note that in this case, all information stored on the device will be erased and cannot be restored. A device that has undergone a factory reset will be the same as it was on the day of purchase - crystal clear. Therefore, you should remove the flash drive and try to transfer all important files to your computer or other accessible device.
1. Soft Reset.
Experts insist that regardless of the problem with the tablet, you should first perform a soft reset, and then, in case of failure, try to bring the device back to life with a hard reset.
A hard reset is carried out in two ways: through the "Settings" menu, the "Restore and reset" submenu, and through the "Recovery menu", or "Recovery menu". Since in the case of a sensor control via the main menu is not possible, only the second method remains.
1. To enter this mode, you must turn off the tablet. Please note that the tablet must be fully charged, otherwise it may turn off at the wrong time and it will be more difficult to restore the system.
2. After the device turns off completely, you need to hold down a combination of several keys (power button and volume control button) and hold until this screen appears:
Photo: Recovery Menu 3. You can navigate the recovery menu using the volume keys, select items with the power button. You need to select "wipe data / recovery reset".
Photo: Recovery Menu 4. The next step is to agree to delete all data from the tablet by clicking on the option "Yes - delete all user data".
Photo: Recovery Menu 5. Now you need to proceed directly to reboot the system by selecting the "Reboot system now" item.
Photo: Recovery Menu After a little thought (which may take a long time), the tablet will perform all the necessary actions and begin to launch.
Please note that this method does not guarantee that the tablet sensor will start working. This is just one of the possible manipulations for his resurrection.
Photo: Touchscreen on the tablet Another reason that the sensor on the tablet does not work or does not work accurately (opens applications instead of simply scrolling through the menu, clicks twice instead of once, etc.), may be its poor calibration (this applies to older devices with resistive displays). In order to calibrate the sensor, you must either use the standard setting using the services of the Android OS, or download applications for calibration (for example, Touchscreen Calibration (Download)), or contact the service center when all other methods do not help.
All of the above tips are not direct directions for action. If you are not entirely sure that you can independently cope with fixing the sensor on the tablet, it is better to contact the service center, where experienced specialists can determine exactly what the problem is and how to solve it.
Dear Readers! If you have any questions or comments on the topic of the article, please leave them below.
In most cases, this concerns ignorance of some of the features of use, as well as a lack of respect for technology. For example, after replacing the touchscreen, part of the screen does not work, and you were sure that you would solve the problem with this method. Obviously, it will not be possible to solve it if the attitude to technology remains the same. Therefore, we will consider all the possible reasons why a part of the touchscreen does not work.
Part of the screen is not working on the phone
So, experts almost always advise using the elimination method. The fact is that part of the screen on an iPhone sometimes does not work due to the simplest little things, which can be easily eliminated, and sometimes you have to completely change the details of the technique.
It is likely that part of the touchscreen on the phone is not working due to one of the following reasons:
- Sometimes part of the touchscreen does not work due to a simple memory overload. In pursuit of getting great opportunities and the desire to store information as much as possible, we do not notice how we simply overload the equipment. As a result, there are no more resources for the touchscreen. And sometimes there is a failure of the equipment system, then you will have to resort to the so-called deep reboot.
- Part of the screen on a smartphone does not work after careless handling. When was the last time you cleaned the screen? When dirt and greasy stains accumulate on it, the contact becomes worse and the sensitivity decreases.
- Technique does not tolerate temperature changes. This is one of the reasons why it is not recommended to carry your phone in a jacket pocket in winter. By the way, such drops can lead to condensation, which also leads to malfunctions. Oxidation of the contacts begins and the sensor jams. In such a situation, it is enough to wipe the contacts with a cotton swab dipped in alcohol.
- In a cramped bus or just in a sharp movement, you will not even notice how you damage your phone. Part of the screen on the phone does not work after the appearance of the smallest cracks.
- It is likely that part of the touchscreen on the phone is not working after a slight displacement or partial peeling of the touchscreen itself. Here you can use the heating method with a hairdryer. The fact is that the sensor is fixed with a small layer of glue, which can be heated and installed in place.

Why does the sensor on the phone not work, does not work well, stopped working, part of the sensor
Modern people, keeping up with the times, have long managed to replace push-button phones with touch-sensitive smartphones. Such devices are more practical and functional, since they can simultaneously perform several tasks.
As soon as you decide to buy a modern smartphone in the Fly brand store, take proper care of your device. Otherwise, you may face such a problem as malfunctioning of the touchscreen (touch panel).
Why the sensor on the phone does not work: the main reasons
- Contamination of the screen surface: if you often have to pick up the phone with dirty hands, prints and greasy marks may remain on the screen, which impairs its sensitivity;
- incorrectly installed protective film;
- sudden changes in temperature can also for a short time affect the smartphone's ability to respond to your requests (for example, if you suddenly go outside from a warm room in frosty weather);
- damage to the screen or ribbon connecting to the touch cover due to falling;
- phone software crash;
- full phone memory, as a result of which it is not able to process the owner's requests;
- contact oxidation due to moisture getting inside the phone or dropping the device into water.
Many of these reasons can cause a number of other malfunctions in the phone. So, for example, if a smartphone is dropped into water, problems may arise with the perception and reproduction of sounds, as well as with switching on. Find out what to do if your phone has fallen into water and won't turn on so you can quickly fix the problem at home.

The sensor on the phone does not work: what to do to fix the breakdown?
Your actions in this situation will directly depend on the cause of such a failure. In some cases, you can independently and fairly quickly solve the problem that has arisen.
So, for example, if the touchscreen does not respond to your touch due to surface contamination, carefully wipe the screen with a special liquid for display cleaning and a soft, clean cloth.
If the screen protector is not properly installed on your phone, dust, dirt, and voids may form between the screen protector and the screen surface, making it difficult for your fingers to contact the sensor. It is enough just to replace the protective film, having previously cleaned the screen from dirt.
If, after a fall, the sensor on the phone stops working, the reason may lie in the cracks and damage to the loop. It is not worth eliminating such a breakdown yourself. In most cases, the only effective solution is to replace the screen at a service center.
Free legal advice:
In some cases, the malfunctioning of the touch panel can be caused by a software failure. You can solve this problem by flashing your smartphone.
If the sensor on the phone does not work for no apparent reason
If a sensor malfunction occurs suddenly, it is necessary to diagnose the phone and look for the exact causes of the breakdown. For this purpose, it is better to contact the service center. An experienced wizard knows all the tricks of setting up Android and will be able to determine and eliminate the reason for the lack of response on the touch screen of your smartphone.

The touchscreen does not work on a mobile phone: we fix it ourselves
Free legal advice:
Good day, dear reader!
Today I will tell you a story from my life. This is not just a story, this is some kind of practical advice. It is not for nothing that this article is placed under the heading "Everyday matters."
I have several phones. Yesterday on one of them the touchscreen (or touch screen) "died" - a touch screen that completely replaces the physical keyboard.
As usual, he partially "died", but this was enough to completely paralyze all the work.
Light spot
Sensitivity has disappeared on the narrow strip on the right. The phone was turned off at night, and in the morning I tried to turn it on. This procedure is accompanied by a password entry. And I need this narrow strip on the right, since I'm using the number located there.
As a result, I could not even turn on the phone. As usual, calls began to service centers and replies: "Leave your phone number - we will call you back, as we check if we have such a touchscreen or not." As a rule, everyone promised to call "today or tomorrow." What should I do right now?
Free legal advice:
In general, there was only one bright spot in this whole story - the Internet. Why light? Because 99% of your questions you will always find answers on the Internet! I found the answer too.
Which? I'll tell you now.
Where to get it
If the touchscreen is “covered with a copper basin” on your phone, you will need a piezoelectric element to “resurrect” it. Where can I get it? Of course, in a piezo lighter. But I don't have a piezo lighter at home: with a handle, on a wire or on a battery - there is none.
But there is a piezoelectric element. It is installed on the hob of my gas stove. By turning the knob of the burner, I turn on the gas. At the same time, I push the handle down and turn on the piezoelectric element. This is how I light the burner.
In general, I need a piezoelectric element, but no gas is needed. I turned off the gas tap. Turned off my phone. I brought it to the piezoelectric element with the screen: the place in which my touchscreen "died". I switched on the piezoelectric element and moved the screen for a few seconds so that the spark covered the “dead” area of the touchscreen.
Free legal advice:
After that, I turned on the phone, and - lo and behold! - the touchscreen is working! He really recovered! He became fully operational!
The effect lasts ...
Various sources on the Internet report that the effect of such resuscitation lasts from several days to one month. Today is my second day, as the touchscreen "came to its senses" - everything works perfectly.
Of course, it is imperative to replace the touchscreen, but reanimation from a piezoelectric element as a momentary method is just great!
If my solution will help you, I will only be glad! Have you had a sudden "death" of the touchscreen at the most inopportune time? How did you solve this problem?

Very interesting. I would never have guessed to use a piezoelectric element to resurrect the phone. In my practice, this has not happened yet, the phone did not fail by itself. There were problems with the batteries, due to the depletion of their resource. Took note of your case. Thanks.
Timur, I would never have guessed either. While looking for a solution to the problem. I read about one more method: swipe the phone screen across the TV screen. I have a regular TV, not LCD. This is what you need to use. I tried it, and it didn’t work. And everything worked out with a piezoelectric element from the hob, which plunged me into indescribable delight. And I immediately shared this method))
Real miracles of technology) Thank God, I have no problems with the phone, but now I know for sure how to urgently revive it)) There would be some other method of increasing the RAM of a laptop using a frying pan or repairing an air conditioner using raw smoked sausage))) ) More often share such extraordinary solutions to everyday problems) thanks)
Hello Mihas! That's exactly what I reasoned when I was looking for a way to reanimate the touchscreen. And when I read about using a piezoelectric element (and before that - about a TV screen) as a tool to return the touchscreen to normal operation, I grinned for about five minutes. Exactly until the moment the touchscreen started working)
In general, in the world, as I understand it, there are many all kinds of ideas and methods that initially cause a smile and even laughter, and then surprise and even amazement. It was exactly amazement that I experienced when I revived the touchscreen with the help of a "lighter" located on the hob of my gas stove))

As I understand it, we are talking about electric ignition on a gas stove? For a year now, the strip on the touchscreen phone has not worked for me, I also rummaged in the internet, I did not find anything like it. Should the phone be sparked? I'll go and try)) There is nothing left to lose the phone))
Anastasia, I used the ignition, which is built into the hob of my gas stove)
The narrow strip on the right did not work for me either: it was probably 5-6 centimeters wide. I turned off the phone, turned on the piezoelectric element and moved the "dead" area of the screen over the spark so that it touched this area. Just a few seconds. Then he turned on the phone. And that's all. It worked))
In my situation, a complete replacement of the touchscreen was required. The phone fell on the asphalt unsuccessfully and the screen crashed. As a result, it was repaired for me for a week, they were looking for parts for a long time, some kind of special tape. The repair cost 3 thousand rubles.
Good evening, Vladimir!
Free legal advice:
The touchscreen in my situation also needs to be changed. I have already reanimated it in the way that I gave in the article))
The point is simply that such an option is momentary. Here is to call right now or record a contact from the address book. For such a case, the use of a piezoelectric element on the hob is a very good solution))
Sergey, good evening! Indeed, the most curious way. Someone thought of this! So far, the only touchscreen phone in our family is out of order - that of our eldest daughter. Once I reanimated it by resetting it to the factory settings, hitting a menu with a bunch of lines consisting of hieroglyphs - I chose a line at random, I was lucky. Now, when he died for the second time, I will try to replace his firmware - also according to instructions from the Internet)
As they say, one head is good, but two are better. And the Internet contains ideas and practical ways to solve various everyday problems from a huge number of people. The scale of the information presented is enormous - the whole world!
It is not surprising that on the Internet you can find answers to almost all questions, since, probably, any life situation that happens to a person has already happened to other people. And some, the smartest or the luckiest, have certainly already found a way to emerge victorious from it. And you just need to find a way to solve your problem, which someone has already thought of)
Free legal advice:
I will add: I thought of it and did not keep silent about it, I shared the method with others. Many specialized forums and communities contain so much useful information that it only remains to be surprised and admired) Well, and use it as needed.
Constantine, I agree with you. Today, in fact, there is a huge amount of information. In this situation, the main task is to be able to find the right one.
It seems to me that the Internet today has answers to almost all questions. If 20 years ago it was necessary to plunge into some serious problem on its own and spend a huge amount of nerves and time on its solution, today, in order to solve the overwhelming majority of questions, it is enough to be able to search and find answers. And that they are, I personally have no doubts.
If the question is specific - you are right, Konstantin - it is often enough to find a popular and authoritative thematic forum, register there and ask for help. They will definitely help!
Sergey, thanks for the advice. As soon as touch phones appeared, I immediately had a concern about this kind of malfunction. I haven't even bought a smartphone for a long time. But time went on. I didn't want to walk with a model from the age of dinosaurs, I bought it. There are no problems yet. But as they say, it is better to arm yourself with knowledge for the future. It is especially useful for women for us to know “what to do” so that we do not become hysterical in a problem situation.
Good day to you, Arina!
You're right. Useful little things never get in the way. If everything works for you now, that's great! And let it be so! Let your touchscreen never "die". And even if you change your phone for only one reason - you just want something new!
But if, God forbid, something happens, if something somewhere stops responding to touch, you will already be fully armed. And remember how to reanimate the "dead" zones. And if you don’t remember, go to my blog and read it again))
Not only an article on restoring the touchscreen, but also any other articles - go to my website and blog, read, leave comments! Always welcome!
Sergey, hello! I haven't been to your site for a long time. And here you can find and read a lot of interesting things. So in this article I saw such an original solution for the "resurrection" (albeit temporary) of the touchscreen. And, most importantly, how! I would never have guessed that a gas stove not only helps to cook-fry-grill, but also repairs smartphones.
I am taking it into service. Moreover, I had a similar case earlier. Then I had to change the screen completely. 🙁
Hello Vitaly! Glad to see you)
I want to say that a similar method is not a complete solution to the problem, but a very effective measure to revive the phone "here and now".
You need to find someone's phone number, right now you have to call or you need to call yourself, you need to send an SMS with congratulations, and then - bam! - the touchscreen is "blown away!"
It is precisely in this situation that the proposed method of reanimating it is the most working, and in many cases the only option to get out of a difficult situation.
But then, when the priority issues (urgently call, send an SMS, find a phone number) are resolved, then you definitely need to change the touchscreen)
The main thing is not to forget to turn off the gas. 🙂
Yes, yes, you correctly noticed it))
Otherwise, instead of reanimating the touchscreen, you can empty the family budget for a new phone, because now when the phone fails, often a person is left not only without household communications, but also without the ability to fully work. After all, the telephone today for many is the Internet, it is communication with customers on Viber and a whole bunch of other things!
I unsuccessfully flashed my smartphone and got a "brick" as a result. Now I go with a rarity of shaggy years. 🙂
Well, old phones are sometimes more reliable than the latest models))
Today's ones fell to the floor - that's it: the screen cracked, the scratches started. If there are a lot of applications or viruses, the device slows down.
And as it was before ... Nokia 3210: even if they have nuts, at least talk to a friend, at least do these two things at the same time - everything works out great!))
By the way, I revived the touchscreen and forgot about this problem for a couple of days. Then he "died" again. I revived him again. Then again. And then, during the next resuscitation using the piezoelectric element of the hob, I was slightly electric shock, and the touchscreen "died" forever. That's when I had to honestly go to the repair shop and change the touchscreen.
As I said in the article, it is imperative to replace the touchscreen. "Resuscitation" is a temporary measure to "revive" the phone "here and now". And then the touchscreen still needs to be changed.
What I did not expect to read on your site is such a life hack. The decision, although "dumb", but the godfather needs quick results why not !?
Alexey, of course, this method is just a temporary option. It in no way replaces the need to visit a repair shop to replace the touchscreen.
However, as a temporary measure, when you need to get a badly needed number out of your phone or call urgently right now, this is one of the most effective ways.
And this method helped me. Otherwise, I would simply not have mentioned it. I was able to call and get contacts. Twice in this way I brought the touchscreen back to life. But a few days later he died forever.
And I took the phone to the workshop, where within three days (the model is not new already) they brought it back to life)
Really the way helped. Only I took apart the lighter with a piezoelectric element and clicked it on the non-working area of the screen. The touch worked. Thanks to the author.
Sergey, hello! I write only about what really works, only about what I personally tried)
I am glad that the method helped you. While the phone “came to life”, do everything that you have planned (call, copy messages and phone numbers) and then be sure to hand it over for repair to replace the touchscreen.
As I already said, the method described in the article is an excellent option for bringing your phone to life in the here and now format. But it does not restore the touchscreen to work forever. After a while, it will stop working again. Then the method I described will help again. Then again. And then the touchscreen will "die for real." Therefore, do not forget to promptly replace it.
There is a SUPRA M727G tablet, it did not fall, there was no input, but the touchscreen was turned off on the left. Many people on the network write that the method with a piezoelectric element is working, so I think, maybe my plonchet is not the same, or they are making fun of the network 🙂
The 100% method is not working, I personally have not been helped by one method from the network. Of course, the tablet itself is not expensive, it's easier to throw it out and buy a new one, it keeps one, in perfect condition, it's a pity to throw it away
Yes, of course, the method presented in the article is not a guarantee of the result. I got Windows 10 here, about which I wrote an article "Windows 10 does not start after changing the boot parameters: how to fix it without reinstalling the system", so Microsoft technical support told me a proven method of restoring the system while saving user data, but immediately made a reservation that There is no 100% guarantee of success.
On the other hand, I always write only about what I have verified on my own experience. The method with the piezoelectric element helped me. I think it works most of the time. It worked for me.
At the same time, the proposed option is definitely temporary. It is designed to revive your device for a short time. But then it must be taken to the service.
I think this is exactly what you need to do in your case: if none of the temporary options works, then it is easier to take it for repair. At least, you definitely don't need to throw it away.
Damn, I was sure until the last that it was a divorce! Especially when the spark from the lighter did not fire on the screen! But, she hit the metal body several times, right next to it. AND?! Damn, it works. I was amazed. Thanks! For a long time no one surprised me like that!
Good evening to you, Vasily!
When my touchscreen was "covered" and I discovered a method with a lighter on the Internet, it was just wild) That is, it was generally illogical and wrong.
As if I had read that in order to fix the water tap, you need to break a glass of red wine against it so that it stops "running."
And I just decided to give it a try, because right now there were no other options. I tried it. And the touchscreen is working! To say that I was surprised is to say nothing))
Guys, it really works….
Good evening, Mikhail! Of course it works)
I would not even think about writing an article if I had not tried this option myself and personally made sure that it is a worker)
I confirm the way to restore the sensitivity of a part of the sensor on an Acer phone
I walked around the screen with a manual piezo lighter to ignite the stove - and for some reason the screen started working
I'm shocked by the way
I hope it will work for a long time
Good morning to you, Sergey!
It's nice that this method helped you. Of course, it is not a panacea and may not work at all in some situations, but in most cases it still works)
But regarding "it will work for a long time" I will say that it is better not to hope. This method is a stopgap measure to make emergency calls or get a contact out of the phone. Then it must be returned for repair.
Congratulations to all those who have earned it. After the described procedure, the width of the "insensitive strip" increased from 5 mm to a quarter of the screen.
I just recently thought that this method probably does not help everyone, and someone, after all, may not get the effect of such a procedure. And then you appeared)
In fairness, it is worth noting here that if you decide to resort to the touchscreen resuscitation option, then it is already inoperative for you. Therefore, using the method presented in the article, you can revive it, but you may fail. But I'm sure you did everything right by trying to bring the touchscreen back to life before taking it for repair.
P.S. You know, I reanimated my phone using the method described in the article two or three times, after which the width of the "insensitive strip" also expanded to the area of the entire screen. It is possible that you have gone too far with the number of contacts of the piezoelectric element with the surface. That is, at some point, resuscitation did take place, but the procedure did not stop, which led to the "death" of the neighboring areas of the touchscreen.
Sergey, thank you very much!
When I drove the tablet over the spark, I giggled, but whatever you do out of despair, the tablet is only six months old, all the more you don't need to open the tablet, the warranty will not be affected. As my friend said, explaining why she dyes her hair every month: you have to try everything in life!
You should have seen my stunned face when the dead strip on the touchscreen started working. And I've been washing it for a week!
My wife is grumbling, but at least to hell, after this dance with tambourines on your tip I already believe in everything, even in the fact that I will find a young, beautiful, rich and deaf-mute. Good luck.
Nikolay, good morning to you! If I ran a competition for the brightest and funniest post, you would certainly become the winner))
Nikolay, I sincerely congratulate you on the resuscitation of your tablet! And I am very pleased that it was my article that helped you. Here I am sitting so all contented, pre-contented and smiling)
I wish you a good day and a great mood. However, I am sure that you are always in a wonderful mood. And this is great!
Nikolay, check out my blog. Always glad to see you)
Abaldet. I thought a divorce. BUT .... I can't believe my eyes. Thank you very much, Sergei. I really don’t know how long this will be enough, but the process itself is amazing.
Good evening, Vladimir! Here I have the same emotions and the same resume (in the style of "Stunned! I don't believe my eyes!") Was the result of resuscitation of the touchscreen in a similar way))
As for the timing. After the first resuscitation, the phone worked for me for several days. Then I brought him back to life in this way. He has worked much less. And then, with another attempt, the touchscreen has already "died" to be honest.
Vladimir, this is in any case a temporary measure, but it seems to me that it is the most effective if you need to return a full-fledged touchscreen for a while, and, accordingly, a full-fledged phone to life.
I bought a new phone for 20 days, but not in a store and without a guarantee, not most of the screen at the bottom on the right does not work correctly, for example, instead of the letter 6, it writes 3, it's dumb, but if I have to change the touchscreen, I'll try. Thanks for the advice, it's funny, but after reading the reviews, it's useful.
This is how the touchscreen “dies”. I have often had the same thing. At first, "centering" is lost: I press one number or word, and a completely different one is displayed. And after some time, the area where numbers and letters are written crookedly simply dies off.
Valery, I think it's time for you to change the touchscreen. And before that, you can extend his life in the way specified in the article.
Thank you Sergey. I did the calibration with two applications, it did not help.
Valery, then it's time to try the method described in the article. If you decide, please write whether it helped or not.
First, I want in the service center to check, maybe the loop has gone away, and it's sad that there are no touchscreens for it, I looked on the internet and did not find it.
Weird. It seemed to me that the Internet has everything)
Although, no, I remember looking for a charger for one ancient phone - I never found it.
People, in any case do not do as it is written in that article. A high-voltage pulse can disable the smartphone's electronics and you will now get a full-fledged "brick", all these laudatory reviews about the method are fake, be careful with such would-be advisers, they just troll you.
Master with many years of experience.
Eugene, good day to you!
If you indicated your website or page in social networks, I think many would definitely turn to you for advice. Strange, but when searching for your Email in My World, the page of the woman Albina, who is 43 years old, flies out. Do you know why this is happening?
Eugene, it seems to me that in this case you are not advising, but dissuading. In other words, you tell the person in response to his confused question about what to do with the "dead" touchscreen: "Don't do this." What to do? Carry to the service? So this is a no brainer!
But the point is that we are considering a situation when you need to urgently call or fish out a contact. Right now! Otherwise, everything! What to do? Your answer: "Nothing can be done already."
Just do it! And I did it. I reanimated the phone in this way. Moreover, several times. Have I put my phone in danger? Of course. But the fact is that the phone has already "died". The touchscreen is an element of “smartphone electronics”. This element has just been covered. And it needs to be reanimated. You need it right now! How to do it? The method in the article talks about this.
I myself tried this method - I succeeded: I reanimated the touchscreen for a few days. Does this method provide a guarantee of recovery? Of course not! I even write in the article that this is not a replacement for repair, but a chance to bring the phone back to life for a short time.
Eugene, I still ask you to indicate your page or site. And then your message and your regalia are somehow frivolous - "a master with many years of experience."
Maybe someone knows where you can buy a touchscreen for the Leagoo KIICAA Power phone
Valery, I may be wrong, but it seems to me that there is everything on the Internet, for example, on aliexpress)
Thanks for the hint, it helped a lot, before I couldn’t type a three, I was typing, now everything is ok
Sergey, good morning to you!
It's nice that the advice in the article was useful to you. At the same time, do not delay replacing the touchscreen. Next time he may "die" forever)
This method of resuscitation is an effective measure for many, including me. However, this is only a temporary solution. Then the touchscreen must be replaced.
There was the opposite effect, in the evening I put it on charge, took the body in my hands, and it itself presses into the same current on the wheelbarrow.
It’s impossible to do anything at all, not to call, not an SMS, there was no gas stove at work and a piezo lighter too, but there was a shocker from Alishka, banged into the touchscreen and really everything began to work with a bang, I’m waiting for it to die completely. But the method is cool, I would never have guessed it myself.
Roman, good afternoon! It's great that you managed to revive your gadget using the method described in the article!
“.. I’m waiting for him to die completely…” - I think that one should not wait for this sad moment. It is better to take the phone to the service so that it will serve you for a long time. And if he starts to be capricious again, you can use "shock therapy" again)
OOOOO. NO FIG CE!)))) Thank you so much for the advice, the strip on the left did not work, after the shock therapy it flies like new)))
Good evening to you, Irina!
It's great that you did it too)
Respect and uvazhuha!)) For a month already suffered from a similar problem! I would never have thought that this way you can cure a touch, but a miracle happened.)) Thank you!)
Alexander, good evening! It's great that you did it. And it's nice that it was my article that helped)
I would like to note once again that this method is just a temporary measure that can revive the phone in a situation when nothing else helps. It is imperative to replace the touchscreen with a new one!
Hello. And what could cause such a breakdown? The stripe on the right does not work on my phone. And sometimes it works, but not more than an hour. I'll try tomorrow. Would a piez element from a lighter work?
To answer the question, what could be the cause of the breakdown, you need to hand the phone into the hands of a specialist. There are many reasons: from damage to the board to water ingress.
Of course, a piezoelectric element from a lighter will do. And it is more convenient to use it than the piezoelectric element, which is discussed in the article.
I would not have guessed either, in short, after replacing the touchscreen with a non-original one, the strip from the bottom does not work for me, somewhere about 5 centimeters, I used a tutch for a temporary installation, an ordinary piezoelectric element from a lighter, I just have an electric stove, not a gas one, but a piezoelectric element can be and just in case, carry it with me, put it in my pocket, and that's all))))
Hello Ruslan! So did you manage to restore the touchscreen? If yes, then I sincerely congratulate you! And traditionally I will already note that this is not an absolute, but a temporary solution to the problem. As soon as you managed to make an emergency call, "pull out" the contact and send a message, it is better to immediately take the phone to the service and replace the touchscreen.
Ruslan, Happy New Year to you! Good luck, success and prosperity!
Happy New Year, too. Of course, I will change the touchscreen, only this time I will put the original one so that there are no dead zones with a motor.
Thank you very much for the tip, about the piezoelectric element, and even forgot to write, people write that they are breaking through the tatch, and then they turn on the phone, and the sensor works, but I do not turn off the phone at all, and I do not have to break through the entire non-working area with a spark /
When I'm texting VKontakte, and a series of letters on the keyboard. refuse to work, then I just hit one of the non-working buttons of the keyboard with a spark, sometimes once is enough, and sometimes it is necessary several times until it works, but I hit one of the letters, at one point, but then the whole row of buttons works, and then the whole keyboard works like this
Ruslan, just on a working device at the moment of touching a spark, all electronics can fail. It can come out on the switched off phone, just the probability is higher on a working device.
In any case, it's nice that my advice helped you!)
The most effective way to return the phone to work like a store and in some cases even better is to put it in the microwave for 45 seconds. No more no less otherwise 2 options 1-will not recover and will not help, 2-display will melt. I myself work in a workshop, suckers pay well for this and carry packs of phones, half of them are being restored.
I wonder what do you do if your microwave strategy fails and your phone is completely out of order? The client brings you a phone, the problem of which is that the sensitivity has disappeared in a separate area, and you return the phone to him with a melted display and with the words: “It cannot be repaired. Contact another service "?
Kind of weird. I don't really believe that you are working in the service. It feels like you have previously tried to “cook” the phone in the microwave at home, and in half of the cases you have achieved just such a result.
No, Gagarin, so that not 50/50, but all 95%, you need to pull the magnetron out of the microwave and from a distance of 1 m for 90 seconds. irradiate the phone. Yes, a prerequisite: hold the magnetron with your hands. If it doesn't work, i.e. you get into these 5%, you can indulge yourself with the thought, maybe they will give you a Darwin Prize.
Gagarin, you yourself are suckers and are looking for someone to drag you to your workshop. You are a clown, not Gagarin ...

Interview with me
For Avangard Blogosphere magazine: a blog is a great tool for getting clients.
To blogger Konstantin Vervekin: a good copywriter is a demanded copywriter.
« The touchscreen does not work"- this is one of the most common problems faced by the user of a modern smartphone, phone or tablet.
In such a situation, the simplest and correct solution would be to contact the service center, where qualified specialists will help you.
If you nevertheless decide to do the repair yourself, then our advice will definitely come in handy.
Before buying a new touchscreen, check your gadget model and touchscreen labeling. It is worth paying attention to the size and location of the proximity sensors, front camera and speaker holes. This is especially true for devices that are manufactured in China. For more information on how to choose the right sensor for a Chinese gadget, read our article.
Removing the touch screen
Before ordering a screen, we advise you to figure out if you can technically make a replacement yourself. Quite often, special hardware is required to peel off a touchscreen. When disassembling a tablet or phone, remember the entire disassembly sequence, the location of the screws, plugs and latches. You can order the most necessary tools for disassembling the gadget.
Be extremely careful when disassembling the device, as you can accidentally damage internal elements that are located close to the edges, for example, cables, power buttons, side buttons, antenna, etc.
Having disassembled the device, remove the touch screen... An important role is played by how the touchscreen is attached to the matrix: monolithic or separately.
There are modular (non-collapsible) models and those with which you still have to tinker. The sensor itself can be connected to the printed circuit board bus (wires) or contact method... If shield connected by bus, be extremely careful not to damage it when removing it.
Everything is much easier with contact method(simple contact of contacts). Here, the sensor is simply removed.
If you come across a device where you need to disconnect the glass or display from the sensor, and they are glued all over the area photopolymer glue, then we recommend using a special separator for gluing such assemblies.
Be sure to watch the video, how to use the separator correctly to detach the glass from the display module.
To work with a separator, you will also need:
To reassemble such a module, you need special glue.
Our video will help you choose the right glue specifically for your device.
To glue the glass neatly and securely, use a clamping mold and an UV lamp.
If you're lucky and the touchscreen was removed with the front panel, but without the display, then that means that it was glued to double-sided tape.
You can mechanically peel off such tape using a thin, flat object. If the glue is stronger, then you will have to preheat the glued surface using a hot air soldering station. Warm up very gently so as not to damage the plastic frame.
How to choose a touch screen?
Did you manage to disassemble the gadget? Congratulations!
Proceed with the selection of the required part. As we have already written, important factors when choosing a spare part are the version and markings of the touch screen.
It is also important to determine the thickness of the double-sided tape. If the layer is too thick, the sensor will bulge out of the rim. Conversely, if the tape is too thin, then there is a high probability that after assembly the sensor will stick, not work, spontaneously work or not work at all. Note! In many models it is absolutely impossible to allow the sensor to directly touch the display or the metal frame!
If the touch screen did not work the first time, this does not mean that it broken or defective! The most common mistake is sensor substitution. Never allow the sensor to touch the display! It is also worth checking the sensor contacts to see if they are fully inserted. It may be necessary to clean the contacts on the ribbon cable and on the connector to which the touchscreen is connected with an eraser, as they can oxidize.
After checking the correctness of the connection, start working on the software compatibility of your gadget with the new touch screen.
You need to force the sensor controller to overwrite the new touchscreen data. To do this, you need to turn on the tablet without connecting the sensor. During boot, the system will reset the controller firmware. After the update, the OS will boot. Further, the sequence of actions is as follows:
without turning off the tablet, remove the battery → connect the sensor → turn on the tablet → the sensor firmware is being updated.
This procedure is called touch screen calibration... It is also used in case of incorrect sensor triggering, inverse triggering, sticking (hypersensitivity) or, conversely, poor sensor sensitivity. It so happens that the calibration has to be done using special programs that can be found on the Internet.
In some cases it is required full flashing of the gadget... The software must either be updated to the latest version, or, conversely, rolled back to the previous one. In such a situation, it is worth contacting specialists or experimenting with different firmware.
Sometimes it is not necessary to reflash at all, but it is enough to do HARD RESET... For each model, this procedure is done differently, information on how to carry out such procedures is publicly available on the Internet.
Note! All software update procedures may result in the loss of personal information. If you decide to manipulate the OS, take care of saving your notebook, photos, videos and other important information in advance.
If the touch screen is not working, you can save information using a computer mouse or keyboard connected via a special OTG cable.
There are also situations when it is necessary to carry out not one, but several of the above procedures, for example, first reflash, and then calibrate again.
If you have already tried all possible calibration methods, the old sensor is broken, but it works, but nothing works with the new one, that is, there is another way to make the new touchscreen work.
It happens that the controller, which is soldered directly on the screen cable, is simply incompatible with the version of your device (especially for tablets from China). In this case, it is necessary to unsolder a suitable controller from the old sensor and solder it to the new touchscreen. This procedure can only be carried out having some experience... If you are counting on a possible return of a part, first coordinate your actions with the manager who served you! Careless soldering will void the warranty for this touchscreen.
Is the sensor working? Fine!
However, take your time. Remove the inner protective film from the touch screen and collect the gadget possible only after a full check of the touchscreen.
If you still fail to achieve the desired result, you can return the touchscreen back (subject to warranty requirements). For more information on the procedure for returning goods, see the page
ALL SPARE PARTS wants your touch screens to always remain intact, well, if a problem has already happened, we will try to provide you with all the necessary spare parts. Good luck with choosing and replacing the touchscreen!
Natalia ZinkoModern mobile devices cannot be imagined without touch screens. Therefore, it is necessary to decide what to do if the sensor on the phone does not work only after studying the events that led to the breakdown. The screen is the main part of modern smartphones, without which they lose all functionality.
In order to find out why the sensor on the phone does not work, you need to carefully study the smartphone. Sometimes problems in the phone are visible to the naked eye, for example, if the screen is broken, and in some cases, the performance may be lost for no reason. Ingress of moisture, rough mechanical impact and much more can affect the serviceability of the device.
If the source lies in a software failure, then a situation may occur when the gadget does not respond correctly to your touches. Such problems often arise due to the actions of the owner himself, who, through negligence or inexperience, made changes to the operation of the system.
Typical touchscreen faults
The most common reason why the touchscreen does not work is mechanical damage. Shocks and other influences can lead to negative consequences. The most neutral will be chips, more serious problems will appear with the formation of a "cobweb" in which the apparatus can continue to function.
Since modern smartphones are quite fragile devices, even after falling from a height of human growth, it stops working. If the device continues to function, and the damage is caused in the form of cracks in the case or its deformation, the cessation of the operation of a part of the screen, then it is necessary to contact a specialist as soon as possible to carry out repair work.
Another popular cause is moisture ingress. Despite the fact that the device looks like a monolithic device, it has small slits and gaps through which liquid enters the main board.
Moisture and liquid penetration into the phone case
The ingress of moisture into the cellular mobile leads to the onset of the oxidation process of the contacts and the board. If the gadget is in a similar situation, then you shouldn't disassemble the smartphone without special need. The first thing to do is dry the device. If drying does not work, then it should be taken to a specialized repair center, which is especially true for expensive models, interference with the internal circuit of which leads to irreversible consequences. During the repair, you can use a cheap replacement of the device, which will receive calls and SMS.
Elimination of oxide
In some cases, after moisture has entered the gadget, after a certain time it will start to work, but badly or incorrectly. In this case, you can try to eliminate the oxide that arose upon contact with the liquid on your own.
To do this, you need a tool with which the oxide will be removed (a plastic card, a screwdriver, and so on). Also needed: rubbing alcohol, toothbrush, eraser and tissues. Before disassembling a smartphone, you need to read the instructions that can be found on the Internet.
The cleaning procedure must be carried out carefully, as any awkward movement can lead to additional damage. The disassembled gadget must be folded onto a sheet or napkin in such a way that it can be easily assembled, as shown in the drawing. Each place must be wiped with alcohol, an eraser and blotted with a dry napkin.
If traces of rust were found, then it is removed with a toothbrush. The place is treated with alcohol, the remaining corrosion is removed with an eraser.
It will be especially difficult in cases where the cause was a sweet drink. The impact of such a mixture has a chance to disable the gadget, and without the intervention of a specialist, the repair will be impossible.
Dirty display
If the display gets dirty without damaging the screen, then just wipe the sensor thoroughly with a cleaning liquid, and then remove the remaining moisture with a dry cloth. To preserve the display, it is recommended to use a protective film that can be easily glued on and removed in case of contamination.
Loop damage
Damage to the loop of the device is one of those causes of breakdown that cannot be eliminated at home. Therefore, if the sensor sometimes does not work correctly, it is worth contacting a specialist who, with a guarantee, will be able to restore the device to work.
Software glitch
- Restart your smartphone. In some cases, the changed settings of the software will not be applied after the system is rebooted.
- Use the built-in sensor test program. To do this, you need to enter a combination that is unique for the device of each brand.
- Check the temperature of the device and place the device in a favorable environment.
- Check the operation of the memory card and SIM card.
- Load the gadget in safe mode.
In some cases, the problem can be solved with these simple methods. If the attempts have not yielded any results, then it is worth contacting the masters.
