Modern mobile devices cannot be imagined without touch screens. Therefore, it is necessary to decide what to do if the sensor on your 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 your phone does not work, you will need to carefully examine your smartphone. Sometimes problems in the phone are visible to the naked eye, for example, if the screen is broken, and in some cases the functionality may be lost for no reason. Moisture ingress, rough mechanical impact and much more can affect the serviceability of the device.
If the source lies in a software glitch, then a situation may occur where the gadget does not respond correctly to your touch. 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.
Common touch screen problems
The most common reason why the touchscreen does not work is mechanical damage. Impacts and other impacts may cause negative consequences. The most neutral will be chips; more serious problems will appear when a “cobweb” forms, in which the device can continue to function.
Since modern smartphones are quite fragile devices, even after falling from a height of human height, it stops working. If the device continues to function, and the damage is caused in the form of the formation of cracks in the case or its deformation, or the cessation of operation of part of the screen, then it is necessary to short terms contact a specialist for repair work.
Another popular cause is moisture ingress. Despite the fact that the device looks like a monolithic device, it has small cracks and gaps through which liquid gets onto the main board.
Moisture and liquid entering the phone body
Moisture entering a cell phone leads to the beginning of the oxidation process of the contacts and the board. If the gadget finds itself in a similar situation, then you should not disassemble the smartphone unless absolutely necessary. The first thing you need to do is dry the device. If drying does not produce results, then it is worth taking it to a specialized repair center, which is especially true for expensive models, interference with the internal circuitry leads to irreversible consequences. During repairs, you can use a cheap replacement device that will receive calls and SMS.
Oxide Elimination
In some cases, after moisture gets inside the gadget, after a certain time it will begin to work, but poorly or incorrectly. In this case, you can try to independently eliminate the oxide that appears upon contact with the liquid.
To do this, you will need a tool with which to remove the oxide (a plastic card, a screwdriver, and so on). Also needed: alcohol, toothbrush, eraser and napkins. Before disassembling your smartphone, you need to read the instructions, which 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 so that it can be easily assembled, as per the drawing. Each place should be wiped with alcohol, an eraser and blotted with a dry cloth.
If traces of rust are found, it is removed with a toothbrush. The area is treated with alcohol, the remaining corrosion is removed with an eraser.
It will be especially difficult in cases where the cause is a sweet drink. Exposure to such a mixture has a chance to damage the gadget, and without the intervention of a specialist, repair will be impossible.
Stained display
If the display becomes dirty without damaging the screen, then you just need to thoroughly wipe the sensor with cleaning fluid, 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 applied and removed if dirty.
Damage to the cable
Damage to the device cable is one of those causes of breakdown that cannot be fixed at home. Therefore, if the sensor sometimes does not work correctly, you should contact a specialist who can restore the device’s functionality with a guarantee.
Software glitch
- Reboot your smartphone. In some cases, changed software operation settings will not be applied after a system reboot.
- Use the built-in sensor testing program. To do this, you need to enter a combination that is unique to the device of each brand.
- Check the temperature of the device and place the device in favorable conditions.
- Check the operation of the memory card and SIM card.
- Boot the gadget in safe mode.
In some cases, the problem can be solved by these in simple ways. If your attempts have not yielded any fruit, then you should contact the experts.
A touch screen phone is a very functional and convenient thing. However, the more high-tech the device, the easier it is to damage it. The sensor (touchscreen) is the “Achilles heel” of modern gadgets, because it is very fragile and is constantly subject to mechanical stress. Careless users can place a bag on it, sit down, flood it, or even throw it against the wall in a fit of anger. And now the long-suffering phone comes to a point when the touchscreen sensor no longer responds to finger touches. What to do if the phone no longer obeys its owner?
There are many reasons why the touchscreen does not respond to touch. The main triggers are hardware damage, which can only be diagnosed and repaired at a service center.
What to do if the touchscreen on your phone does not work:
- First, pay attention to the neatness of your phone. Dirt or oil stains may cause the touchscreen to respond incorrectly to user touches. Therefore, do not be lazy to regularly wipe the screen with a microfiber cloth. This simple cleaning can get it back into working order. In addition, make it a rule not to handle your phone with dirty or wet hands.
As practice shows, in cases where the sensor on the phone does not work, the problem lies in the touchscreen. According to statistics, in 90% of cases, replacing the glass on your phone will help restore full functionality. And only in 10% the reason lies in other details.
If your touchscreen doesn't work, don't try to repair your phone yourself so you don't have to buy a new one later. Replacing the glass on a phone should only be done at a specialized service center using original parts, since counterfeits quickly become unusable and cannot be repaired.

Free legal advice:
If you are not experienced in repairing mobile devices like yours, the only way to revive it is to take it to the nearest service center. But if you are a professional, you can change or repair your phone’s touchscreen. Look at the purchase documents, if the warranty has not yet expired, you can try to return it again to the store.
You can’t do it yourself. Try to remove the battery for about 5 minutes. If it doesn’t help, then call it for service. The warranty does not cover such damage.
Most likely, the phone will have to be taken to the trash. The only way to make a phone yourself is to look on the Internet to see if they sell a screen for it that can be replaced. Buy a new screen, try to disassemble and rearrange the screen. or take it to a workshop, but usually it’s not worth it; they charge a lot for repairing phones. After trying to remember the screen yourself once, now if the screen cracks or does not respond, the phone is sent to the trash or to the bulletin board for a ridiculous price.
I had similar case when the touch phone stops responding to touch. I wrapped it in a bag and put it in the freezer for 10 minutes, after which it started working, but lasted for 2 days. Then I repeated the procedure with the freezer, and the phone started working again. Now it no longer responds to the freezer, so I changed my phone number not long ago.
I had this with touch phone. The warranty has already expired, and changing the sensor would cost more than new phone, I just bought a new phone.
Free legal advice:
If your phone is still under warranty, contact the warranty. If not, try putting it in the freezer for 5 minutes, without the battery only. If it doesn't help, you'll have to buy a new one.
If the touch screen does not respond to touches, and the phone’s battery is working, I think you can limit yourself to two options - return it to the store if the service warranty period has not expired, or take it to a service center, and they will decide whether “the patient is most likely alive.” or not .
If the touch screen stops responding to touch, then the batteries may simply be low. If everything is fine with the batteries, then it is better to contact customer service or buy a new one. In my opinion, aging in the freezer is just a joke.
A friend of mine had the same situation. But the phone stopped responding to touches after it had been in my pocket for a long time. severe frost. He simply turned off the phone for 48 hours and then turned it on. Everything worked.

What to do if your smartphone's sensor doesn't work?
Gadgets
Devices with touch screens are functional and convenient, but their reliability is questionable. Various problems often arise with their use. Taking into account the fact that mechanical control buttons on modern devices have become a rarity, the user often completely loses control over the device.
Free legal advice:
Problems do not arise out of the blue; this usually happens after the smartphone is dropped or moisture gets inside it. What to do if the sensor does not work?
Why did the touchscreen fail?
There are various reasons leading to device failure:
Dirty display.
If your screen gets dirty for some reason, then a drop in sensor sensitivity will be a completely natural phenomenon. To deal with this problem, just thoroughly wipe the screen with a special napkin.
Damage to the cable.
The element connecting the board and the touchscreen may have jumped out of the connector or been damaged. The problem will be solved if you open the device and carefully insert the cable into place. If there is no visible damage, try taking it to a service center.
Moisture has entered the phone.
If water gets into your smartphone, oxidation occurs. In this situation, you can open it and carefully clean the contacts with alcohol. If your actions lead to nothing, take the gadget to specialists.

Software glitch.
Sometimes problems arise with the firmware of the device, and you have to reflash it. To do this you will need a cable and the software itself. Usually this procedure is not difficult, just install the drivers and use the installation program.
How to change the touchscreen?
If the sensor no longer responds to your touch, and you have checked the cable and firmware, it’s time to use it effective method replacing the touchscreen. It doesn’t matter what exactly caused the breakdown, changing it is quite simple.
First comes the disassembly procedure. Remember everything you do, put the screws in a separate box so as not to lose them. There is a high chance that you will have to work with latches during the process.
When the device can be completely disassembled, remove the touchscreen. At this stage, it is important to pay attention to whether the screen is monolithic or the touch panel is a separate element. If the module is solid, then changing it is easy; in the case of a collapsible one, you will have to tinker a little.
If the matrix needs to be disconnected from the sensor, arm yourself with a regular hairdryer and warm up the display. Do this carefully, avoiding overheating. Then we disconnect it using some thin object. Then we glue the new touchscreen to the display. For this, glue is used, sometimes it is already applied to the purchased part.

The sensor on the phone does not work: what to do
A touch screen device is functional and practical. Unfortunately, the reliability of such screens is low and the question of what to do if the sensor on your smartphone stops responding is very often asked on various forums.
Since the phone no longer has control buttons, all functions of the device are lost in one second. Troubles usually begin after the mobile phone is dropped or moisture gets inside, or it may stop working on its own, as happens with Chinese phones.
Reasons for the touchscreen not working
There are various reasons that can lead to such a malfunction:
The phone's memory is overloaded and the device does not have enough resources to process clicks.
In the video, the sensor on the phone does not work, what to do:
Display dirty
Over time, the sensor may become covered with fingerprints or grease. This leads to deterioration in the sensitivity of the touchscreen. You need to thoroughly wipe the screen with a special liquid and a dry cloth.
Unsuitable temperature conditions
A sudden change in temperature may cause the device to stop working.
The cable is damaged or has come loose
It provides a connection to the touch surface. You can solve this problem yourself with a small screwdriver if your phone is out of warranty. If you have a warranty card, of course, go to a service center.
Due to moisture getting into the phone
When liquid gets inside the gadget, oxidation occurs. Try drying your device with a hairdryer.
Oxidation of contacts
This problem can be eliminated by careful cleaning.
Software failure
You need to reflash the device. To do this you need to have software and USB cable.

How to reanimate a sensor at home
The very first thing to do is to restart the phone, while removing the battery and SIM card. Sometimes you need to reset your phone to factory settings. If a deep reboot did not help, then when performing further actions you need to understand all the risks and responsibilities.
In some phones, to get to the buttons you will need to disassemble the entire body of the device, and for this you need to study the sequence of disassembling the device. Without knowing this, there is a possibility of damaging the device, and the cost of repairs will be much more expensive.
Armed with special tools, carefully remove the touch screen. After this, you need to carefully inspect the cables and connectors. The operation of all functions of the device depends on their integrity. If there is no damage, then simply disconnect the display from the board and connect it back.
Since the phone has already been disassembled, carefully wipe the dirty contacts on the board with a cotton swab and alcohol and put the phone back together.
This clever way makes it easy to put it in place.
When all the screws are tightened and the assembly is complete, you can install the battery and turn on the phone.
If after all the manipulations no changes have occurred, and the touchscreen still does not work, then replacing the touch glass will help you. This is something that is extremely undesirable to do at home and you cannot do without a service center.
You can find out how to find a person by photo on the Internet using your phone or tablet by reading this article.
You need to monitor your touchscreen phone and handle it more carefully than a push-button phone.
Do not drop it and do not allow moisture to get inside, and then you will encounter such problems less often.

Phone Samsung s 7262, the screen was accidentally pressed, the sensor began to glitch, when entering words without touching the screen, it happens that he presses the letters himself, you have to turn the screen off and on
Hello everyone, there were similar problems with the Samsung Gakaxy Tab 3, the phone tablet fell a lot and in fact the whole body looked like it was after a bombing. Over time, the sensor began to fail, namely, when the processor overheated, the screen stopped responding; it worked, but did not respond to touches. I disassembled it at home, completely checked the processor myself and didn’t understand anything, but after reassembly everything worked fine. Yesterday, after an “accidental” hit on the screen, this problem arose again. I tried to solve it by blowing out the cable, blew it out, connected it, worked for several hours, and closed it in the morning. No matter how much I blew into it or picked at this cable, it didn’t matter to him, I had to peel off the screen and get to the screen chip. As it turned out, the blow was straight to this very chip. Another cable was connected there, I removed the film, took out the cable, inserted it back - it didn’t work. Well, I think that’s it, I’ll have to fork out more money, but I remembered that there was a video on YouTube where a guy doused the screen with electricity from a lighter so that some areas would return to working condition, I decided to try: I punched the main loop, it didn’t work, I punched the chip loop, it didn’t work, I shocked the chip, the sense came back. I’ll say right away: this may be a simple luck, and in your case it will not help, especially for those who have a non-removable panel, but often breaking through some elements saves the life of the equipment. Don’t repeat this on new phones, and especially on those that have a warranty, but for those who like to experiment and who don’t really need their device, go for it, maybe it can! All the best and cookies, maybe it helped someone.
I didn’t find the video, but the advice with the current helped) thank you.

Find a person using push-button telephone, today is quite difficult: the vast majority of users choose convenient, multifunctional touch screen gadgets. However, the “lifetime” of these devices is short: fragile glass sometimes only needs a small blow or careless pressure to become cracked. Like push-button devices, they deteriorate due to moisture getting inside the case or falling from a height.
A faulty phone stops responding to touches on the screen, and sometimes does not turn on at all. To understand which element of the electronic circuit is damaged and replace it, you need equipment that only employees of specialized service centers have.
The touchscreen has stopped responding: your actions
The absence of a touchscreen response does not always indicate a breakdown.
- Dirt or greasy stains adhering to the glass can distort the electronic signal and reduce the sensitivity of the sensor. Constantly wipe the screen with a clean cloth, removing fingerprints, until the shine is completely restored. It is best if the cloth is made of lint-free microfiber. Clean glass completely restores its functionality. From now on, try not to touch the phone with dirty or wet fingers.
- Sometimes the touchscreen stops working after re-sticking the protective film. This happens if the film is glued carelessly, there are air bubbles between it and the glass, or dirt has gotten in. Remove the film and re-glue it more carefully, or contact your nearest service center about this.
- In some cases, the reason for the failure is a settings failure. The phone stops responding adequately to pressing touch keys. Try rebooting the device, if that doesn’t help, reset the settings to their original state.
Possible damage to the phone
Practice shows that the most probable cause Partial or complete failure of the touchscreen causes cracks in the glass. Sometimes they are almost invisible, and you have to carefully inspect the screen to detect them. The consequence of their appearance may be a loss of screen sensitivity in certain areas. It is impossible to restore full functionality on your own: the touch glass must be replaced, which is performed at a service center. Up to 90% of all malfunctions of modern phones are eliminated by replacing the touch screen.
About 10% of cases are caused by the breakdown of other components and components. If the phone was subjected to shock or dropped from a height, this could damage the chip that controls the touchscreen. In addition, the microcircuit can fail if even a small amount of moisture gets inside the case. To restore functionality, you need to remove the faulty element and install a new one.
A modern phone is a complex electronic device, and incorrect operation of the sensor can be caused by the breakdown of a number of components. For example, a failure may be caused by the break of one or more traces on a printed circuit board due to shock, shock, or oxidation caused by moisture. Only full testing using special instruments and software can determine which electronic components have failed.
If none of the methods listed above helped to revive the phone, then there is nothing left but to buy a new touchscreen and contact specialists for installation.
Attention!
Don't try to replace a broken touchscreen yourself! Inept actions can lead to a worsening of the situation until the phone completely fails. Available only at the service center necessary equipment for a neat, technologically advanced touch glass replacement. Do not purchase cheap no-name analogues of original components for repairs, as their use can lead to complete burnout of the electronic circuit without the possibility of restoring functions.
The more you paid for your new phone, the greater the fear of waiting for problems with its operation. Unfortunately, sometimes we are not even aware of the sources of problems in technology for various reasons. In most cases, this relates to ignorance of certain features of use, as well as careful attitude to technology. For example, after replacing the touchscreen, part of the screen does not work, and you were confident in solving the problem using this method. It is obvious that it will not be possible to solve it if the attitude towards technology remains the same. Therefore we will consider everything possible reasons, why part of the touch screen does not work.
Part of the screen on the phone does not work
So, experts almost always advise using the method of elimination. 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 parts of the equipment.
Part of the touch screen on your phone is probably not working due to one of the following reasons:
- Sometimes part of the touch screen does not work due to simple memory overload. In our pursuit of greater opportunities and the desire to store as much information as possible, we do not notice how we simply overload our equipment. As a result, there are no more resources left for the touchscreen. And sometimes the equipment system fails, then you have to resort to the so-called deep reboot.
- Part of the screen does not work after careless handling. When you're in last time did you clean the screen? When traces of dirt and greasy stains accumulate on it, contact becomes worse and sensitivity decreases.
- The technique cannot tolerate temperature changes. This is one of the reasons why it is not recommended to carry your phone in your jacket pocket in winter. By the way, such changes can lead to condensation, which also leads to problems. The contacts begin to oxidize and the sensor starts acting up. 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 sudden movement, you won’t even notice how you damage your phone. Part of the screen on the phone does not work after the smallest cracks appear.
- It is likely that part of the touchscreen on your phone is not working after a slight shift 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 set everything in place.
Components of electronic devices may break if used carelessly. If part of the touch screen on your phone does not work, this may be caused by both temperature conditions of use and mechanical damage.
Competent diagnostics will help you repair a smartphone or tablet screen 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 taken to the service, and this may lead to additional costs.
Causes of failure
There are the following reasons why part of the screen does not work:
- Oxidation of contacts due to condensation. Moisture trapped inside the device can lead to complete or partial loss of functionality. Oxidized contacts stop responding to processor commands and transmitting 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 alcohol applied to cotton swab or a tampon. After this procedure, the phone should turn on in normal mode.
- Cracks on the surface of the screen. Due to microdamage to the sensor, it stops responding to pressure. 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 restore functionality using the device.
- Disabling touchscreen contacts as a result of displacement. This usually results in the bottom or top half of the screen not working. To diagnose contact displacement, you need to disassemble the device and see if the visual order of the symmetry of the components is broken. If you see misalignment of the contacts, you can try to correct them using tweezers. In addition, some elements are fixed with glue, which can melt at high temperatures and displace the contact. In order to upper part returned to its place, you need to heat the mount with a hairdryer and return the component to its original position.
Features of the operation of electronic devices
In addition to the listed breakdowns, electronic devices may begin to malfunction due to the peculiarities of the internal architecture. Limiting the size of components affects their power reduction if the tablet screen does not respond to touch - this may be a consequence of overloading 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 device’s central processor and disable unnecessary applications.
Electronic devices have increased sensitivity of screen sensors. A situation where the screen of a tablet or phone does not work may be due to simple contamination. The adhesion of grease and dust to the surface causes the tablet to not respond to touch.
If the screen on your tablet does not work, 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 under warranty, perhaps you should just buy a new gadget and subsequently treat it more carefully.
