Modern gadgets have become an integral part of our life. The phone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water, or software glitches. The most common problem faced by many mobile device users is that the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact the service center. Otherwise, do not rush, because there are times when the problem can be easily and quickly eliminated. The sensor does not respond to touch, what should I do in this case? Let's take a look at all aspects of this problem.
Phone screen repair
Before solving the problem, you need to make sure what is the reason for the breakdown of your display. This can be mechanical damage, liquid getting inside the device, or a software failure. If you are sure that you did not drop your phone or spill liquid on it, then we can assume that this is a software glitch.
Mobile phone screen cleaning
First, you can simply clean the display of your device. You will not harm the phone in any way, but you will improve the connection and, perhaps, the problem will be solved. This method can help if the sensor is not responding to touch. What to do?
We take a suitable cloth and liquid to clean the screen. Better to use a lint-free or any other natural fabric. To clean the display, we need a glasses or monitor cleaner.
If this method did not help, then it is worth moving on to the next steps. Of course, they may not help either. Only a professional can establish the true cause of the breakdown, but he can not solve every problem.
A software glitch that caused the display to break
If the display of the mobile device reacts to your touches in places, then you can try to make a Hard Reset of the system, this is a complete reset of the settings. But keep in mind that this can only help if the sensor is buggy from time to time. After performing a factory reset, install applications that can clean up the system registry. This will eliminate errors caused by RAM. Recommended apps are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but it has good functionality. The first program is for you if you are not sure about the reason why the display does not respond well to touch, and you are not going to spend money.
All actions should be performed without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card in place and check the device with an antivirus. Select full device scan and wait. But even after the performed actions, the sensor does not respond to touch. What to do? In this case, it is necessary to proceed to replacing the sensor, since the cause is not caused by a software failure.
Mobile phone display replacement
The sensor does not respond to touch - what should I do? If the previous methods did not help, then it is necessary to replace the damaged display. Most often, this should be done when the device has fallen, cracked or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. Thus, condensation that accumulates in a mobile device will interfere with the normal operation of the phone. At first, black spots may appear when working with the gadget, and in the future, the sensor itself will stop responding to touches. In this case, you will need to change the screen.
Phone screen repair is not a very difficult process, the main thing is care and accuracy. Anyone can do this. The sensor does not respond to touch - what should I do? First you need to disassemble your device, but you should remember the sequence of actions so that in the future there will be no problems with the assembly. All plugs and latches can be removed with a thin object. You will need to carefully remove all elements from the latches with this object.
After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, since when ordering a new screen, this aspect will have to be specified.
The sensor can also be connected to the PCB in a variety of ways. There is a contact method, in this case the sensor is simply disconnected, and wired. In the latter case, you should be very careful.
If you need to detach the matrix from the sensor, you must follow these recommendations:
- First warm up the surface to 60 degrees. This can be done with a regular hair dryer. It should be heated evenly so that the glass does not crack and the glue heats up.
- Next, you need to find a flat and thin object to easily detach the sensor from the matrix. To do this, simply pry off the edges and gently lift.
All that remains is to attach a new sensor. How to do it? The kit should include the sensor itself and the glue. First, we apply special glue, and then carefully attach the sensor.
The cost of a new display
How much it costs Of course, the cost of the screen will differ for different models of smartphones. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, you will need to pay about 700 rubles.
If you do not want to disassemble the phone yourself, you can contact a specialist. The master will ask for about 2,000 rubles. Although this procedure is not very complicated and you can change the screen yourself. Only this will need to be approached carefully and carefully.
Touch buttons do not work
The lower touch buttons are directly related to the screen and in case of their failure, it is necessary to do all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clean the system registry and check your device for viruses. Unfortunately, if the above steps do not help, then you will need to change the screen.
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 to service centers began 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?
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.
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?
A touchscreen mobile phone has recently become one of the most popular phone models, because it is easy to use, and thanks to new technologies, it is possible to significantly increase the size of the screen without increasing the dimensions of the phone. A mobile phone with a touch screen requires careful and careful handling, because any shock or damage can damage the sensor, as a result of which the phone will stop responding to touch.
If a part of the touch screen does not work, it is imperative to find out the cause of the breakdown. Very often, due to impacts and damage, cracks appear on the touchscreen, which can lead to the fact that some area of the screen is out of order. In such a case, only replacing the phone's touchscreen can help solve the problem. You need to find out which part of the touchscreen is not working. The problem may also be in the telephone loop. When dropped or bumped, it can come off, so the screen contacts do not respond well to touch. This is the reason that the phone does not always respond to pressing.
If half of the touchscreen does not work, we can say that the touchscreen contacts, which are connected to the main board of the phone, have come off, and the signal is not transmitted correctly. That is why one half of the screen can adequately respond to touches, and the other half works only when the touchscreen is pressed hard enough. In this case, the phone must be carefully disassembled and looked at the touchscreen contacts. You need to do everything very carefully, since the device contains many small parts, having lost them you will have to go to a phone repair shop.
The touchscreen of the phone may also not work due to the fact that some parts are out of order, but such cases are quite rare, since almost always the problem lies in the touchscreen of the phone itself. There are also cases when the touch screen of the phone does not work after hypothermia. This happens especially often in winter. There is no need to panic, you just need to wait a little while the phone heats up. After that, the screen will work properly again.
Disassembling the phone is appropriate if dirt or moisture gets into the middle, this can also provoke the failure of certain parts of the screen. After everything is removed, you need to carefully reassemble the phone - the screen should work properly. In any case, be sure to consult with a specialist in this area.

Screen on your phone?
Electronic components can be damaged if used carelessly. If a part of the touch screen on the phone does not work, it can be caused by both temperature conditions of use and mechanical damage.
Repairing a smartphone or tablet with an insensitive touchscreen can help you deal with major issues. Sometimes a simple cleaning in combination with disassembling the case helps. However, if after all user actions the device does not turn on, it must be transferred to the service and this may result in additional costs.
The reasons for the break
Read the same
There are the following reasons why a part of the screen does not work:
- Oxidation of contacts due to condensation. Moisture trapped inside the device may cause to complete or partial loss of performance. Oxidized contacts stop responding to processor commands and transfer them to the screen. To eliminate the effects of liquid spills, the device must be disassembled and the internal components cleaned. To do this, you can use rubbing alcohol on a cotton swab or swab. After this procedure, the phone should turn on normally.
- Cracks on the surface of the screen. Due to micro-damage to the sensor, it stops responding to pressing. There is such damage due to falling or bumping on the screen. You can identify cracks in a display by carefully examining its surface. If part touch screen is covered with cracks, it is possible to restore operation by replacing the touch screen of the device.
- Disconnect the touch screen pins due to misalignment. This usually does not work in the lower or upper half of the screen. To diagnose contact misalignment, you need to disassemble the device and check to see if the visual symmetry of the components is out of order. If you see misaligned contacts, you can try to fix them with tweezers. In addition, some elements are attached to an adhesive that 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 holder with a hairdryer and return the component to its original position.
What if any sensory screen doesn't work?
Part of the touchscreen is not working? There is an exit! with the help of a piezoelectric element from a lighter that we are restoring.

Features of the operation of electronic devices
In addition to these failures, electronic devices can start to fail due to internal architecture. Limiting the size of the components affects power dissipation if the tablet screen does not respond to touch - this could be due to an overload of the device with a lot of resource-intensive applications. To prevent it, you need to start the task manager. Find out what is using the processor and disable unnecessary applications.
Electronic devices have increased the sensitivity of screen sensors. The situation when screen the tablet or phone does not work, it may be associated with trivial pollution. The attachment of grease and dust to the surface causes the tablet to become unresponsive to touch.
If the screen does not work on the screen - the best solution is to send it to the diagnostic service center. Most models come with a very long warranty, which will allow you to replace the device at no cost, no defects or money back. If a deal isn't guaranteed, you can probably just buy a new gadget and take care of it later.
Modern tablets are controlled primarily through a touchscreen. If the touch layer suddenly stops working on the tablet, it becomes almost useless. But how can you save the device in case of such a breakdown?
The main reasons for a non-working touchscreen can be summarized as follows:
- Software glitch. The sensor is the main control element, it is not easy to make it lose its functionality. But this happens - for example, if you install the firmware on the device from another modification.
- Mechanical breakdown. Modern touchscreens are often very reliable and continue to function even when cracked. But this applies to expensive devices from Apple and other first-tier manufacturers. If you use a budget tablet, then its screen may suddenly fail without external signs. If the sensor does not work on the tablet, look for impact marks on the case, but do not be surprised if you do not find it.
- Calibration failed. This applies mainly to older devices with resistive displays.
- Drowning. Water that gets into the tablet case can get to the sensor controller and disable it. Without any external signs, the tablet suddenly loses control.
- Initial defect. In tablets from respected manufacturers, sensor defect is extremely rare. But if you handed it over for repair or bought already "restored", then, perhaps, now the device has a non-original touchscreen. And its lifespan may be much shorter than the original. What to say about inexpensive nameless Chinese, the quality of which no one controls!
What if the touchscreen doesn't work?
- Try just restarting your tablet. To do this, just use the power button.
- If a simple reboot does not bring the sensor back to life, try hard reset (). All user data will die during a hard reset, but we hope you managed to pre-configure cloud sync so that everything of value can be restored.
- If there is a protective film on the screen, remove it. Low-quality film can reduce the sensitivity of the display so much that it becomes impossible to use it.
- Wipe the screen from fingerprints and other debris.
- Use only original or quality third party charger. When using cheap Chinese chargers, problems with the operation of the touch screen are often observed: sometimes it does not respond to pressing at all, sometimes "phantom pressing" appears. At first, this only happens when the charger is connected. But frequent distortion of the sensor can lead to damage.
- If your device has a resistive display, try recalibrating it. A built-in calibration tool is usually found in the operating system.
- If you tried to reflash the tablet and after another attempt the sensor refuses to work, try returning to the original firmware version. True, now this will have to be done with the help of a computer. Apparently, you can do this yourself, since you managed to install the “wrong” firmware yourself.
- If all of the above does not help, go to a service center.
- Explaining the problem to the specialist, tell us about everything that has happened with the tablet recently. If you dropped the device, drowned it, got into the rain with it, or handed it over for repair earlier, do not hide it. So the master will quickly understand the cause of the problem and can more easily fix it.
What to do to prevent the problem from recurring?
- Buy a good case for your tablet that can protect it from moisture and mechanical damage.
- Handle your gadget more carefully.
- Discard cheap accessories. Repairs are more expensive than you save on "nameless" charging. Better to spend on original or quality China (say Orico, Blitzwolf or Ugreen).
- If the service center offers you a replacement for the touchscreen, it is better to insist on installing the original one. Although, weigh the pros and cons: maybe it will be more profitable to buy a new budget tablet every year?
- Necessarily, ! The problem with the touchscreen will prevent you from quickly saving data before repairing.
