The tablet stops responding to touch. Problems with the tablet sensor. What to do? Simple solutions to complex problems

The weakest point in any tablet is the screen. Of course, from year to year, manufacturers are installing more and more durable and improved glasses, but even they sometimes fail. And today we will figure out what to do if the tablet does not respond to touch. Touchscreens are not only affected mechanical stressbut also physical: falls, water, scratches and even cracks. Thus, dropping your gadget or pouring it with morning coffee, you can say goodbye to correct recognition of clicks. On the other hand, the problem is not always the physical impact: sometimes the display refuses to recognize fingers in certain applications.

What to do if your tablet is not responding to touch

In the event that your device is still under warranty, you should not try to repair it yourself. In the case of physical damage, it is also better not to meddle - you run the risk of doing more harm during repairs due to negligence. It is all the more desirable to have special equipment and knowledge of the internal arrangement of elements. Therefore, trust the professionals.

By the way, in some tablets you can replace the sensor itself, while in others it comes with a matrix to save space and improve the picture quality due to the absence of an air gap. In the second case, you will have to pay for the replacement of both the sensor itself and the matrix.

Simple recovery methods

In fact, in most cases, you can fix the malfunction with improvised means. Let's figure it out:

Perhaps the tape was incorrectly glued and now the clicks are recognized every other time. It is necessary to peel off the film, wipe the display with a soft, lint-free cloth so that there are no stains or streaks left, then stick the film again. It is best to take a new one, but if the old one “sticks” well and has not lost its properties, you can return it to its place;
If the root of the problem lies in the software and just a couple of minutes ago the device worked correctly, and now it does not recognize pressing, you should restart the tablet. Of course, since there is no access to the screen, you will have to use one of two methods: remove the battery or hold down the “Power” button until the tablet is turned off;
In case you have a very old gadget or imported from China, a resistive-type display can be installed in it. That is, it reacts not only to fingers, but also to pressing any other object. Calibration can help here, but on condition that touches are not recognized accurately. For example, when typing a message, click on "Y", and you will always find yourself on "C". Go to the settings and find the "Calibration" item there, tap on it and follow the system prompts;
Does the tablet stop responding to clicks in certain applications? Try reinstalling them. If this does not help, then there is a possibility that the software on your device is outdated or the game / application developer simply forgot to add it to the list of supported gadgets. In the first case, an update will help, in the second, you will have to wait for actions from the developer;
Physical impact - liquids, condensation, shocks and falls. If, because of them, the tablet ceased to function, then the road to service center Provided for you.

Do not forget that if you nevertheless decide to see what happened from the inside, then do not damage the cables (contacts) that connect the board and the display, but we still recommend not watching the video, but go to the master!

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 water / dust ingress 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, it is necessary to turn it off immediately after detecting the ingress of liquid into the tablet 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 tablet (drops, bumps) or extreme 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, you will have to replace the touchscreen. If the sensor stops working due to exposure to too low or high temperatures, then the best solution - wait, the fault should go away by itself.

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 reboot the tablet and let it rest for a while, since the gadget could freeze due to a large number running applications, causing the sensor to malfunction. 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 dubious applications. After these operations, you need to reboot the device.

The next way to solve the problem with a broken 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 do a soft reset, and then, in case of failure, try to bring the device back to life with a hard one.

Hard reset is carried out in two ways: through the "Settings" menu, the "Recovery 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, 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 (off button and volume control button) and hold until this screen appears:

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".

4. The next step is to agree to delete all data from the tablet by clicking on the option "Yes - delete all user data".

5. Now you need to proceed directly to reboot the system by selecting "Reboot system now".

After a little thought (which may take a long time), the tablet will perform all the necessary actions and begin to launch.

Note, this way is not a guarantee that the tablet sensor will start working. This is just one of the possible manipulations for his resurrection.

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, presses twice instead of once, etc.), may be its poor calibration (this applies to old 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 some cases, there is nothing serious behind it - it is common for technology to fail for reasons that users do not understand. Therefore, you should not immediately carry the gadget for repair: you can try to "reanimate" it at home. So, what problems can the owner of the device face and what to do if the sensor does not work on the tablet?

If the sensor does not work on the tablet: ways to solve problems

Cleaning the display. Simple, banal, but often very efficient way. There is slight contamination on the screen that prevents the sensor from responding or protective film glued poorly. All this is easy to fix. It is best to use a special lint-free cloth (such as microfiber) and liquid to clean your monitors.
Return to factory settings. Tablets of different brands have their own Hard-reset features. In most cases, you need to simultaneously press two keys - "home" and "volume up", then - "power" (screen lock button). A message appears on the screen stating that the information is being deleted After that, the device will automatically reboot. But you need to remember that unlike a standard tablet reboot, this method entails the deletion of system information. But sometimes you don't have to choose. If you are performing this procedure for preventive purposes, it will be useful to take care of creating a backup copy of the existing files. This method can help solve the problem of the sensor not working if the failure is caused by a virus. Also, it is not uncommon for the tablet's memory to be overloaded, as a result of which the device begins to freeze, and the user mistakenly associates the problem with sensor problems.
"Emergency help". Problems with the touchscreen are often caused by users. So, for example, if you spill water on the device, you need to disassemble the gadget and dry it as soon as possible. If the cause of the breakdown is another liquid (juice, sparkling water or, even worse, gasoline - you will hardly be able to do without the help of a specialist. Note: you cannot put the tablet (or rather, its parts) on the battery, and dry it with a hairdryer. ways to solve this problem would be to "immerse" the parts in rice groats, which should collect excess moisture. Here you should not rush - it is recommended to try to turn on the tablet again after 3-4 days, not earlier.
Replacing the sensor. Unfortunately, the touchscreen can malfunction without the ability to return it to a working state - no tablet is insured against this, regardless of its price category. There are both factory defects and "secondary" defects caused by careless operation of the device.

Buying a new sensor is not a cheap pleasure. In addition to the fact that the price of a new sensor itself can reach half the price of a tablet, you will need to "fork out" for the services of a master. But in some cases, you can try to repair the gadget yourself.

There are many visual video tutorials on this topic on the net. In reality, replacing the sensor is not that difficult. First you need to disassemble the tablet, after removing all the screws and other small parts. It is important to remember the sequence of disassembling the device.

Next, you need to disconnect the sensor. Most often it is attached with glue. To avoid damage to the device, exposure to high temperatures (about 60 ° C) is required. Due to the lack of special devices, you can first use a hairdryer.

After disassembling all parts, perform the internal "cleaning" of the device (if necessary). Then attach the new sensor "in place" using special double-sided tape or glue.

If the home repair is successful, calibrate the touchscreen using the appropriate settings.

Greetings, dear readers! Today you will find out why the sensor does not work on the tablet and what can be done. You have noticed that the sensor on the tablet has stopped functioning, do not rush to immediately carry it for repair, since there is a possibility that the cause of this trouble is of a software nature. Perform a Hard-Reset of the gadget system in order to return to the original settings. To do this, you need to do the following: press 2 buttons at the same time – « increasing the volume"And" home ", then, without releasing these keys, press Power. You will see a message about deleting the existing data entered by the user. While holding down the Power key, restart the operating system. Do not forget that the information in system folders will be completely removed.

The sensor and touchscreen do not work on the tablet

If your sensor on the tablet is mechanically damaged and does not work (for example, after a fall), the monitor may not show any signs of failure. But the touch screen already needs to be changed. In this case, it is preferable to purchase a separate touch screen.

We also know that the display of tablet devices consists of touch screen and, of course, matrices. If the gadget was damaged after a powerful blow, then most likely you will need change both display and matrix... For Apple, Samsung or Asus brand products, you can buy these components separately.

Coming to completion, it is necessary to first establish the cause of the non-working sensor, and this to a greater extent requires certain skills and knowledge from the owner.

How to change the sensor on a tablet device

First of all, having determined the reason damaged work touch screen, you need to buy all the necessary components for replacement. Each manufacturer supplies elements and components in special kits: each element separately or in a pack of three in one.

So, the procedure is as follows:

Open the device after removing the rubber plugs and screws.
Take the screen and disconnect the sensor, which traditionally sits on the glue to the display. The operation is simple, since the touch screen is fixed on glue and you will need to use a slight temperature effect (approximately up to sixty degrees) for several minutes. The bottom line is simple: heated air is blown onto the display, but this is done carefully and carefully (make sure it does not burst).
Next, you need to lightly pry it off with a thin improvised object and peel it off the monitor itself.
Install the purchased sensor using glue or double-sided tape.
Once you have assembled your tablet device, perform a small display calibration using a specific software on operating system Andriod or Ois.
