Nowadays, tablets are touch sensitive and controlled mainly by touch screen. If for some reason the touch layer stops working on the tablet, it loses functionality and can go to the trash can without timely repair. Is it possible to help the device with such a breakdown?
There are a lot of reasons why the touchscreen does not work correctly (the bottom of the tablet does not work). Unfortunately, it is impossible to describe them all in one article, especially since you still need to write about how to restore performance, so I will try to simply discuss the most common options for why the sensor does not work well. Among them are the following:
- the most elementary is screen pollution. Sometimes you can see an incredibly dirty screen, you just wonder how they brought it to this. So if you also do not like your device, this reason must be eliminated, because dirt can cause the sensor to spontaneously work in some places;
- software failure is not the most common cause, but it also has a place to be. If you install third-party programs often and a lot, they can conflict with each other, causing a wide variety of system failures, so when the screen on the tablet is partially not working, this may be due to a third-party software conflict.
- mechanical damage - if the sensor does not respond to touch in principle, this may be due to injuries to the device due to carelessness. If you dropped the device and immediately after that there were problems such as the inability to unlock it, the reason, I think, is obvious. Below there will be a detailed manual on what to do if the touchscreen does not work due to mechanical damage and how to replace the screen with another one.
What can be done to prevent breakage
First of all, take a cloth (glass cleaner or monitor cleaner will do) and carefully wipe your mobile phone from water and dirt. Wipe all parts of the touch glass, especially the bottom - this half is especially likely to malfunction and malfunction. Even if you suspect another cause of the breakdown, cleaning it does not hurt. If you're lucky and the problem is fixed, congratulations. If not, let's move on to the next step.
Fixing a System Crash with a Hard Reset
A third party software conflict can be resolved with a Hard Reset or System Reset. Remove the memory card from the device in advance: it can also affect its functioning due to the presence of viruses. Perform a hard reset, after which you need to clear the system cache and registry. To do this, you can download any application, for example, WinFixer or Cleaner4.
It helped - put the card back and check it for viruses using any antivirus. It did not help - you probably have damage to the hardware of the device. This means that it is necessary to change its components.
Another case is that the sensor does not work after the firmware. Look for the manufacturer's website and it contains stable firmware versions for the device.
How to fix a tablet yourself
In principle, you can change the touchscreen cable by contacting any technician. But apart from the fact that you will pay for the new component of your device, you will have to give all your best for the replacement process. If you do not want to pay, read the manual on how to repair the touchscreen without contacting specialists. Don't worry, it's not that hard.
It is necessary to take any durable thin object with which you will remove surface elements until you reach the display.
The display is connected to the matrix either monolithically or separately. Remember which method yours is attached to, as the screens differ from each other and you will need to know which one to buy.
The sensor also lies on the matrix - it can be attached with or without wires. If there are wires, be extremely careful and extremely careful so as not to harm once again. It must be removed from the glue, for this we heat the surface to 60 degrees (the easiest way is with a hair dryer. Do not overheat one of the sides so as not to damage the glass). After heating, the adhesive should easily move away from the matrix.
How to glue the touchscreen after the steps above? Together with the new part, a special glue is included. First, we carefully apply glue, and then we put a part on it, fasten it with care.
Well, now you know how to replace the touchscreen with your own hands in case it stops functioning. If it seems too difficult for you to replace the sensor on the device yourself, contact a specialist to repair it. Of course, the question rests on money, and a specialist can bill you with a tidy sum for seemingly simple actions.
After all, what is there to remove the part from the glue and put a new one on the glue, but everything must be done with the utmost care, otherwise you risk damaging the matrix and generally losing the opportunity to bring the tablet back to life. So before doing any manipulations, I strongly advise you to think it over carefully.
Conclusion
I hope our tips have helped you. Try the universal algorithm described above, or watch the instructional video below. See you on the pages of the site!

First, let's figure out why tablet sensor not working?
Tablet sensor not working?
We constantly print, enlarge, draw “patterns” of rare “beauty” with our fingers - all these actions are common to every person, and for this we buy tablets. But sooner or later we run into a problem where the sensor on the tablet stops working, no matter Lenovo you or Samsung Galaxy Tab, iPad or Prestigio!
The touchscreen is the primary way you interact with your installed apps and is therefore a vital component of your tablet. Any damage caused, even the slightest scratch, will be degrade the reliability of a component, and after a certain time, you will somehow encounter a problem when the sensor on your tablet no longer works!
What can be done if sensor not working on tablet?
Next advice, in part, will help you solve problems with the responsiveness of your tablet's sensor. These tips can be applied to iOS, Android and Windows 8.
1. Need more RAM
Free up RAM on iPad
Probably a process restoring the tablet sensor The best place to start is by increasing the amount of available RAM. This may take a while (and may require a reboot in some cases), but it should also give us an idea of how bad things are. Users Android have many options for freeing up tablet memory, such as clearing the app cache or fully optimizing the device with third-party apps such as memory booster.
Problems with memory iPad can easily slow down the response of the touch screen. The best way to deal with this (in IOS 6 and below) is to double-tap the Home button to display the currently open apps, and then press and hold to display a cross at the top right.
If freeing up RAM you see improvements in tablet sensor responsiveness, then that must be the problem.
If touch screen still not working, or you are sure that the problem is completely different, let's consider the following recommendation.
2. Try restarting your tablet
Among other things, the usual troubleshooting can help. When the device is restarted, most applications will be closed. For Android users, this shouldn't be a big deal - all you have to do is hold down the power button and select the appropriate "reboot" action.
Apple iPad owners will need to close all open apps before pressing the Sleep/Wake button.
Windows 8 tablet owners can restart their devices by opening the Charms menu and then clicking Settings > Power > Restart. If the device is not responding, hold the Windows button and the Power button together for a few seconds until the tablet restarts.
So, if after rebooting your tablet, the sensor does not work, go ahead!
3. Use Native Troubleshooting Apps
Often when tablet sensor not working, this does not mean that it does not work entirely! The problem actually can be only in some parts of the display.
Knowing which areas of the touchscreen are unresponsive can be a great help in diagnosing your device; The information will certainly come in handy for any tablet repair master.
Useful tools for checking the non-working areas of your display are applications such as calculators and maps.
So, we have tried to describe the 3 most effective methods for fixing some tablet sensor failures that you can use yourself.
However, as you may already understand, there are problems that are so complex that you may need to take your device in for service. In our service center in Simferopol, specialists are ready to help you even in the most difficult cases.
Today, almost every family has such a multimedia gadget as a tablet. It is bought by children and adults for games, leisure and even work. But this wonderful device has one unpleasant feature - it is quite fragile. And its rather large screen is especially vulnerable. And since the tablet is a mobile device, it experiences vibrations, shaking, shocks in public transport, on the street, shopping centers and other crowded places. Leaving the tablet on a chair or sofa, there is a risk that someone will sit on it. The delicate microcircuits inside often suffer from drops on the floor or when liquid gets on the tablet, if you or your household accidentally spill juice, tea, etc. In general, there are many options for breakage, but the most common is a problem with the screen glass. The glass on the tablet is cracked - what to do and how to replace it at home? Let's figure it out.
Causes of screen problems
How to change or restore the glass on the phone? In fact, the situation is quite common - the device is thin and light, and therefore fragile. Damage to the screen of the tablet is as easy as shelling pears in a variety of ways. Let's list the most common situations in which this happens:
- The fall. This is the most common option. You did not have time to get used to the size and weight of the device, and let it out of your hands. Your family and friends can do the same, let's add pets here too.
- Pressure. Also a fairly common cause of problems with the screen. There are many options - they can sit on a tablet, the screen can be broken by pushing it into a tightly stuffed bag or backpack, when gathering somewhere, it can suffer in a bus full of people, etc.
- Incorrect operation. A crack can appear from a sharp temperature drop, for example, you brought a tablet from a frosty street into a very warm room. In this case, not only the screen may suffer, the electronic filling is also sensitive to temperature changes. We also include screens that are broken when colliding with heavy objects - it is unlikely that a dumbbell falling on the screen can be called its correct operation.
Important! This is not the whole list of reasons why the display of your device may crack or break. However, these are the most common causes of tablet glass breakage, according to service centers.
Does it make sense to do the repair yourself?
How to remove a crack on the screen of a mobile phone? If you are not technically savvy enough, and your tablet screen is cracked, what should you do? Take it to a service center! Especially if the device is still under warranty. If you try to repair it yourself, you will definitely lose the right to warranty repairs.
Of course, a broken display is rarely covered under warranty, but at least you'll have insurance for other damage. The procedure for replacing a new display is different even within the lineup of one brand, not to mention different ones. In addition, this process is not as simple as it might seem at first glance.
However, if you still dare to repair a broken tablet screen yourself, you can expect the following main pitfalls:
- Lack of experience in repairing a device of this class. The replacement process is quite complicated.
- Availability of spare parts. Especially if your device is not the most popular on the market and you are not in a major city.
Important! If it turns out that the repair is still impractical, then take temporary measures to maintain the working state of your gadget using one of the methods below. In the meantime, choose another model for yourself. Our reviews will help you here:
Device
So, is it possible to repair a tablet if the screen is cracked? To begin with, let's figure out what a tablet screen (display) is and what it consists of.
The display is a component that is signaled to display visual information, so it cannot be standalone. And at the same time, it can work by itself, that is, it can be connected to a variety of other devices. Although, in some multimedia devices, the screen is made of a monoblock. In most other wearable devices, it is completely collapsible.
Basically, these are the following components:
- Protective glass or plastic.
- Touch panel (touch screen).
- Matrix, as well as a backlight panel.
Diagnostics
First you need to understand which of the above components is out of order:
- The easiest option - the glass burst, it is also the cheapest.
- Matrix problems are the most expensive option. You can order the desired component on a variety of resources, and even with a matrix and sensors there are no problems.
Important! On Chinese tablets, you can order not only identical matrices. As a rule, they are all universal, and differ only in the way of installation. It is necessary to re-glue the rubber seals, and also take into account the placement of the cable connectors.
When only the glass is broken, the sensor usually works. Often people continue to use such a tablet until it is completely out of service. In a situation where the glass is intact, but the sensor does not work, things are somewhat worse. Let's say you dropped your gadget or something fell on it. It is not necessary to assume that the sensor is broken. Disassemble the tablet and check if the cable has pulled out.
Important! The matrix needs to be changed only when it is partially or completely out of order. But manufacturers often sell screens as a complete set. To save money, we recommend that you run through service centers or search popular Internet sites for a specific component you need.

We figured out the diagnostics, now how to fix the tablet screen.
Screen protector and tape
If you are unable to repair the damaged display glass immediately, there are some ways to get your tablet back up and running. In other words, if only the glass is broken, the screen continues to show the image and the sensor is working, the following method will come in handy for you:
- Wipe the screen from dust and dirt as much as possible.
- Place a sufficient piece of packing tape over the screen and cut off the excess around the tablet. This will allow you to use the tablet with a broken screen further, slow down the development of cracks and the loss of pieces of glass.
Do-It-Yourself Screen Replacement
It's difficult, but doable. There are many interactive tutorials and materials on the net for self-replacing the display and its components. To do this, you must strictly follow their instructions. Find on the Internet how your device is disassembled. This can be done intuitively, there is nothing complicated about it.
Important! Some devices have their own nuances and tricks, be careful.
For disassembly and repair, you will need the following:
- To open the tablet - a mediator, a plastic card or any thin flexible object made of plastic.
- Screwdriver.
- Tweezers.
- New screen.
- Technical hair dryer.
- Stationery knife.
- A piece of soft cloth to wipe the device.
Replacing the tablet display begins with removing the cover and disconnecting the cable, it contains all the information about the part being replaced. Next, you should proceed in this order:
- If there are bolts at the ends of the tablet, unscrew them.
- We pick out the case with a plastic card and pass along the entire perimeter of the device, after which it will be possible to remove the cover.
- We rewrite the marking and all the data from the removed part, which will allow you to purchase a new part for replacement.
To repair the screen, you need to remove it and install new components. This is done as follows:
- To remove cracked glass, heat the body of the device with a hairdryer.
- Pry off the edge of the glass with a knife, warming up with a hair dryer along the way, gradually move around the entire perimeter of the screen, peeling off the display.
- Carefully remove the broken screen, check that small fragments do not remain on the surface of the matrix. To do this, use a cloth or napkin.
- After removing the broken part, take a new screen, remove all protective films from it.
- Try on the frame and stick a new display on it.
Important! Carefully check the evenness of the fit, because it is unlikely that you will be able to reinstall it.
- After gluing, gently iron the glass with a cloth. After that, you just have to assemble the tablet.

Now you know how to fix a tablet if the screen is broken. This will allow you to save personal money and time on the services of a service center, which are often immodestly expensive.
If the sensor on the tablet does not work, the reason may be hardware or software. But only in rare cases, the user can solve the problem himself. Consider all situations, their features and possible troubleshooting.
The touch screen is one of the most vulnerable components of tablet devices. Anything can affect its operation, but here are the most common reasons that affect the touchscreen and its performance:
- mechanical damage - as a result of a fall, the contacts connecting the screen to the board could come off;
- software failure - if the user changed the firmware or it was done in a service center, various operational errors will be heard all the time, they may also affect the operation of the sensor;
- calibration failure - this applies to more old devices with resistive displays, the calibration will have to be reconfigured through the tablet operating system;
- water ingress - moisture leads to oxidation of the contacts and can cause more serious damage, therefore, in this case, the equipment cannot be used until a complete check;
- factory defect - such a defect is detected immediately and must be eliminated in accordance with the rules of warranty service (the tablet can simply be replaced in the store where the purchase was made).
These are the most common problems that happen with tablet devices. But if it is easy to deal with mechanical damage and hardware failure, then software failures require the intervention of experienced craftsmen.
What to do to fix the breakdown
In most cases, the user cannot restore correct operation himself if the tablet does not respond to touch. But there are measures that can prevent the occurrence of more serious problems:
- when drowning, it is necessary to disassemble the device as much as possible (if the design allows) and dry each individual part in a towel that absorbs moisture well - to do this, you will need to turn off the tablet and, if possible, remove the battery from it;
- mechanical failure also requires disconnecting from the network and deactivating the battery - in such a situation it is better not to use the tablet.
With software failures, everything is somewhat simpler. The user can resort to rebooting the system and "repair" the screen.
Fixing a System Crash with a Hard Reset
A forced reboot can be performed on any device. A forced reboot is provided by manufacturers in case the operating system stops responding to user requests. This is especially true for tablet devices, which work primarily through a touch screen. If the OS does not find it or any settings responsible for interacting with this component are lost, it is necessary to “reset” the failure and update the ongoing processes.
To force a reboot, you must hold down the Home key (or Power - depending on the model) with one of the volume keys. Usually in the technical documentation for the device there are combinations with their description, so you need to read the information from the manufacturer.
After pressing the buttons, the system logo will appear on the device screen - Android or iOS. The reboot process may take longer than usual, but as a result, you will be able to restore the OS and the tablet will work normally.
If this method does not work, you need to contact a good service center, but do not try to solve the problem yourself. User intervention can lead to even more failures.
How to fix a tablet - all ways
If the breakdown is insignificant or it was not preceded by any mechanical damage and flooding, you can try:
- remove the protective film or glass, if any - sometimes the protective layer on the screen is too poor quality or wears out faster than necessary, making it difficult to access the sensor, which makes it seem that it does not respond to touch;
- wipe the screen - sometimes it is quite dirty and the accumulated layer interferes with normal response to user requests;
- if the screen stops responding, you need to try to charge the device - there may be failures in the system, due to which the tablet incorrectly distributes energy or does not perceive the end of the charge, continuing to work in standard mode.
Most often, it is possible to fix a tablet only in a service center, since the user himself, without special knowledge, can exacerbate the problem.
What to do so that the problem does not reoccur
- Do not interfere with the firmware of the device - any unauthorized software changes entail failures and errors in the system;
- Do not use non-original components - whether it is a charger or any part that had to be replaced, the use of functional elements from other manufacturers may cause damage to the device;
- Do not try to disassemble the tablet - technical intervention, especially if the user does not have the appropriate knowledge, can violate the integrity of the components.
Any technique requires a careful attitude. Tablet devices are extremely fragile, since most of their design is taken up by the screen. Any mechanical damage can lead to breakage. But this also applies to software interventions - attempts to reflash the OS lead to numerous operational errors.
The touch display often fails, being one of the most vulnerable components of tablet devices. But quite often the reason for this is a mechanical breakdown or violation of the rules of operation. In order not to aggravate the problem, you need to contact a good service center for timely repairs.
Tablet computers have become faithful companions of many people. They allow you to view e-mail, work with documents, play games, listen to music and perform other actions, by analogy with a conventional computer. An unexpected breakdown of a tablet is literally unsettling, forcing users to look for the reasons for its breakdown. The tablet does not respond to touch - what to do?
If your tablet is not responding to touch, it could mean anything:
- The software hung;
- The screen itself is out of order;
- Electronics broke.
There are also many other causes of broken touch screens. For example, some cheap Chinese tablets with resistive screens suffer from loss of sensitivity quite often. And if you happen to buy such a tablet, be prepared for any malfunctions, even if they go beyond logic.
So, how do we restore the sensitivity of a resistive touch screen? First you need to connect a mouse to the tablet and make sure that it moves. This means that the device is not hung. Next, go to the screen settings and calibrate it - you will find the corresponding item in the settings.
The essence of calibration comes down to pressing the points indicated on the screen (it is best to tap with a stylus or any other not very sharp object). Once calibration is complete, tablet functionality can be restored.
Calibration will not be possible if the display itself, which is responsible for the perception of touches, is out of order.
If the device still hangs, you will have to reboot it - to do this, hold down the power button or press the reset button with a needle (if any). After a reboot, the system should be back up and running.. That did not happen? Is the screen still not responding to your actions? Then you have to give the tablet to a repair shop, where specialists will take care of it.
Do not attempt to repair tablet PCs yourself without proper knowledge and tools. Even if you manage to disassemble the tablet, you may not see any traces of breakdowns inside - it is better to entrust the repair to specialists.
We restore tablets with capacitive screens
If the tablet screen does not respond to touch, it is likely that it just hung. You just need to reboot the device by holding the power button– after a while it will reboot, even without confirmation. If this does not help, you should figure out, after which this trouble appeared.
For example, an unexpected loss of sensitivity may occur due to some software that was installed shortly before the breakdown. We can do the following:
- Try to connect a mouse and remove the latest software, then send the device to reboot;
- Reboot the tablet in safe mode, when only system utilities, drivers and programs are loaded into memory.
Removed the last installed programs and the screen was restored? This is possible when certain applications enter into conflicts in the system. In order for the malfunction not to reappear, do not install remote programs or try to find their analogues.
Please note that support for external input devices, such as wired and wireless keyboards, mice, joysticks, and gamepads, is not available on all tablets. Instructions for entering tablet PCs into safe mode can be found on our website - we have already done a review on this issue.
If the tablet stops responding to touch, you can try removing the protective film from the screen. Some films, having a significant thickness, become an obstacle to the operation of capacitive screens. The use of such films should be avoided, despite the significant protection they provide for the display.
Did your tablet screen stop responding to touch after being hit or dropped off a table? Take the device to a repair shop to be examined by an experienced craftsman - self-repair is not possible here.
Filled the tablet with water, juice, milk or any other liquid? This is another reason to visit the service center - here the tablet will be washed, cleaned and returned to its former performance. The most exotic way to repair is to turn off the tablet and wait a few hours. Oddly enough, but sometimes it helps.
It is quite possible that the reason for this is some kind of software failure or overheating of the electronics. If the manifestation of this malfunction is regular, try contacting a service center where professionals will take care of the tablet.
The last resort that allows you to count on the restoration of the touch screen is a hard reset, which can be performed through Recovery Mode (we have already studied ways to enter this mode in our reviews).
