Why the touch screen does not work the touch screen. What if the sensor does not work on the tablet? Causes of malfunction or incorrect sensor work

If the sensor does not work on the tablet, the reason may be hardware or software. But only in rare cases, the user can solve the problem itself. Consider all the situations, their features and possible methods troubleshooting.

The touch screen is one of the most vulnerable components of tablet devices. To affect his work can anything, but here are the most frequent causes that are wagging on the touchscreen and its efficiency:

mechanical damage - as a result of the fall, contacts connecting the screen with a board could move;
software crash - if the user has changed the firmware or did it in the service center, various operating errors I will obey constantly, they can touch the sensor;
calibration failure - it concerns more old devices with resistive displays, calibration will have to configure again through operating system tablet;
ingestion of water - moisture leads to oxidation of contacts and can cause a more serious breakage, so in this case, it is impossible to use technique until a complete check;
factory marriage - such a defect is detected immediately and subject to elimination according to the rules warranty service (The tablet can simply be replaced in the store in which the purchase was made).

This is the most frequent problemswhich happen to tablet devices. But if it simply can cope with mechanical damage and hardware breakdown, then software failures require the intervention of experienced masters.

What to do to eliminate breakdown

In most cases, the user cannot restore the correct work, if the tablet does not respond to touch. But there are measures that allow you to prevent the emergence of more serious problems:

when drowning, it is necessary to maximize the device (if the design allows you to dry each separate part in a towel, well absorbing moisture - for this you will need to turn off the tablet and, if possible, remove the battery from it;
the mechanical breakage also requires a disconnection from the network and deactivating the battery - in such a situation, the tablet is better not to use.

With software failures, everything is somewhat easier. The user can resort to the system reboot and "fix" the screen.

Fixing a failure in the system with Hard Reset

Forced reboot can be done on any device. Forced reboot is provided by manufacturers in case the operating system stops responding to user requests. This is especially true for tablet devices that work mainly through touch screen. If the OS does not find it or knock on any settings responsible for interacting with this component, it is necessary to "reset" failure and update the occurring processes.

For a forced reboot, you must climb the HOME key (or POWER depends on the model) with one of the volume keys. Usually, the technical documentation for the device has combinations with their description, so you need to familiarize yourself with the information from the manufacturer.

After clamping the buttons, the system logo appears on the device screen - Android or iOS. The reboot process can last longer than usual, but as a result it will be possible to restore the OS and the tablet will work normally.

If this method did not come up, you need to contact a good service center, but do not try to solve the problem yourself. Custom intervention can lead to even greater failures.

How to fix the tablet - all the ways

If the breakdown is insignificant or did not precedes 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 low or wears the faster, difficult to access the sensor, which seems that it does not respond to touch;
wipe the screen - sometimes it is enough polluted and the accumulated layer prevents normal response to user requests;
if the screen has stopped responding, you need to try to charge the device - failures may occur in the system, due to which the tablet incorrectly distributes energy or does not perceive the ended charge, continuing to work in standard mode.

Most often, it is possible to fix the tablet only in the service center, since the user itself, without having special knowledge, can aggravate the problem.

What to do to the problem not repeated

Do not interfere in the firmware of the device - any unauthorized software changes entail failures and errors in the operation of the system;
Do not use non-original components - whether charger or any item that had to be replaced, the use of functional elements from other manufacturers can cause the device breakdown;
Do not try to disassemble the tablet - technical intervention, especially if the user does not have the relevant knowledge, can disrupt the integrity of components.

Any technique requires careful relationship. Tablet devices are extremely fragile, since most of their design occupies the screen. Any mechanical damage can cause damage. But this also applies to program interventions - attempts to reflash OS lead to numerous operating errors.

The touchscreen display often fails, being one of the most vulnerable components of tablet devices. But often the mechanical breakdown or violation of the rules of operation becomes quite often. In order not to aggravate the problem, you need to contact a good service center for timely repairs.

Each tablet owner may have a problem with work or screen on. Of course, decide this problem You can easily, simply delivered it to the workshop. There experienced specialists for a fee will be able to return your gadget to life again. But there is another option, you yourself can diagnose and determine why the screen on the tablet does not work.
Before you begin diagnostics, it is necessary to determine the character of the problem. It can be two species, this is a mechanical damage to the screen that could arise as a result of certain actions or software failure. As a rule, mechanical damage can be seen with the naked eye. In such cases, it is better to give your tablet to the master, because without experience and certain skills it will be difficult for it to fix it.
Another character problem is a programmatic program. It can occur by many reasons. For example, the tablet stopped turning on, after charging it, or the installation of which or applications or games. Also, failure can occur as a result of visiting dangerous sites. In this case, the problem can be solved by independently without any assistance and additional spending.
Before starting the tablet restoration, make sure that it has not suffered from any mechanical damage. After that, turn off the battery of your device and wait a few minutes. Next you need to insert the battery back and try to restart the tablet. This procedure allows the operating system about the gadget to completely reboot. Very often, this is quite enough for your assistant again to function normally.
If a this procedure It turned out to be useless and the tablet screen still does not work, you need to try to reset all the settings to the factory. For almost all tablets, this feature is implemented using simultaneously pressing the shutdown keys and adjust the device. If you are all done correctly and the reason exactly in the software fails your tablet must jar, and a menu with settings will appear on its screen. In the menu using the Volume Adjustment keys and the shutdown buttons, select: Settings - System Formatting - Reboot System. After that, your gadget will start again, but it will remove all previously installed games and applications. Thus, you roll back all settings to the initial level.
If the tablet did not respond to keystrokes, you should read the instructions to it. Each device must have its own emergency method of rebooting the system. Before reset all settings, it is recommended to remove from it. sIM card and memory cards.
If the way you have found in the instruction does not work, you need to attribute the tablet to flashing. In such a simple way, you fully reinstall the entire operating system of your gadget. Better do not try to reflash the tablet yourself, it can lead to more deposits.

Ability to manage the gadget with light touch and leafing movements by many users. The number of fans of sensory devices is growing steadily, and with it the number of appeals to service centers with a question about why the sensor does not work on the tablet. Touchscreen fault is one of the most common problems with which you have to face owners of compact and functional gadgets. If the tablet sensor has lost sensitivity or does not work at all, it is necessary to deal with what is the reason, and repair it - on its own or in a specialized service center.

Does not react the sensor on the tablet

Buying a touchscreen gadget, the user expects to work with it easily, convenient and, most importantly, quickly. However, expectations often diverge with reality - the device works flawlessly short time, its components are alternately fail. The first is usually breaking the tablet sensor - it does not work completely or does not work regularly.

The screen loses sensitivity to touches as a result:

installations of poor quality software;
electronics breakdowns;
mechanical damage.

To conclude that the problem is precisely in touchscreen, you should connect a computer mouse to the device. If it works, the display came out, which is responsible for the response to the touch. When the sensor on the tablet does not work, the use of the gadget is extremely difficult - it is necessary to eliminate the problem as soon as possible to avoid inconvenience and prevent the emergence of more serious faults. The best decision - Show the device with an experienced specialist, because to perform diagnostics and repair yourself, without having special equipment, it is extremely difficult.

Cracked the tablet - the sensor does not work

Most problems in the work of the device causes an inaccient appeal and non-compliance with the rules of operation. Insofar as tablet PC It is enough to be mobile in order to carry it with me everywhere, the largest number of faults occurs during the transportation of the gadget. Working with the tablet "On the Go", you can easily smash it - if the touchscreen cracked, you should not postpone the trip to the service center. The wizard tested the device to determine if the screen has suffered from mechanical damageAnd then - eliminate all the problems. Installing a new sensor does not apply to complex procedures, however, for its qualitative implementation still require special knowledge. In addition, it is extremely difficult to purchase an original touch screen for a tablet for a specific trading brand, it is much more convenient to contact a reliable service center - the master will select and install brand components.

To make the sensor not cracked and did not break, it is worth following some rules for operating a tablet. Wearing a gadget is preferably exclusively in special case or a handbag made of soft, neutralizing tissue blows. It is necessary to ensure that the device is transported away from acute items. Tachkinrin can stop working not only because of mechanical damage, but also as a result of the influence of other negative factors - wetting, installation of non-license system software.

How to fix yourself

Gadgets usually fail at the most inopportune moment, and many users, not wanting to spend time on a trip to the workshop, are accepted for repair on their own. Such an idea is not always crowned with success, but each owner of the tablet may try to restore the work of the sensor at home - to configure the touchscreen, restart the device, clean it from dust.

First of all, it is worth turning off and enable the machine - re-start often returns the screenwriting screen. The cause of a malfunction can be in low quality protective film - it is worth removing it to increase the sensitivity of the display. To configure the sensor, you may need to flash the tablet. Before updating the software or return the device to the factory settings, it is worth a copy of all important files that are stored in it.

Another common cause of the sensitivity of the touchscreen is the use of an inappropriate charger. It is advisable to use only original chargingwhich are suitable for the gadget specific model. If the sensor does not work or reacts not to each touch, it is possible that the tablet "is infected with malicious programs, and they should be eliminated by a reliable antivirus. If the listed manipulations did not help restore the device, it is necessary to immediately contact the service center. In addition, it is desirable as you can tell the master about how much circumstances a malfunction was detected for the first time. It is worth reporting whether the device fell and whether water fell on it. Having setting the cause of the problem, the master will be able to change the sensor on the tablet and tell how to avoid such problems in the future.

Sensor does not work - what to do

If the touch screen has stopped responding to touch, the following steps must be performed:

test it using a computer mouse;
check if the charger is properly;
reinstall the operating system;
remove viruses using antivirus;
replace protective film.

If the measures listed above did not help repair the tablet sensor, you should entrust the repair or replacement of the screen by qualified specialists of the service center. Preferred preferably workshop equipped with modern diagnostic equipment and offering profitable terms cooperation. Trust primarily deserve SC, who have extensive experience and offer a long-term guarantee for all types of services. Rates must be moderate, and the parts used are only original.

Modern tablets are mainly managed through the touch screen. If suddenly the touch layer stopped working on the tablet, it becomes practically useless. But how can you save the device with such a breakdown?

The main causes of the broken touchscreen can be reduced to the following:

Software crash. The sensor is the main control, make it so that it fails work, not easy. But this happens - for example, if you install the firmware from another modification on the device.
Mechanical breakdown. Modern touch screens are often very reliable and continue to work, even covered with cracks. But this refers to expensive apple devices and other manufacturers of the first echelon. If you use a budget tablet, its screen can suddenly fail without external signs. If the sensor does not work on the tablet, look for tracks on the housing, but do not be surprised if you do not find it.
Calibration failure. This concerns mostly older devices with resistive displays.
Drowning. Water caught in the body of the tablet can reach the sensor controller and bring it out of order. Without any external signs, the tablet suddenly loses controllability.
Initial defect. In the tablets of respected manufacturers, the sensor defect is extremely rare. But if you gave it to repair or bought already "restored", then it is possible that non-original touchscreen is installed in the device. And his life life can be much less than the original. What to talk about inexpensive nameless Chinese, whose quality nobody controls!

What if the touch screen does not work?

Try just to restart the tablet. To do this, it is enough to use the power button.
If a simple reboot does not revive the sensor, try to make a hard reset (). With hard reservoise, all user data will die, but we hope you have managed to pre-configure the cloud synchronization, so that everything will be valuable can be restored.
If there is on the screen protective film, remove it. A poor-quality film can so much to reduce the sensitivity of the display that it becomes impossible to use it.
Wipe the screen from fingerprints and other contaminants.
Use only the original or high-quality third-party charger. When using cheap Chinese charging, problems are often observed with the operation of the touch screen: sometimes it does not respond to pressing at all, sometimes "phantom pressing" appears. At first it happens only when the charger is connected. But frequent distortions of the sensor operation can lead to its spoilement.
If your device has a resistive display, try calibrating it again. The built-in calibration tool is usually in the operating system.
If you tried to reflash the tablet, and after another attempt, the sensor refuses to work, try back to the original version of the firmware. True, now it will have to do this using a computer. These are you, apparently, you can do it yourself, since they managed to install the firmware "not that" independently.
If all of the above does not help, go to the service center.
Explaining the problem by a specialist, tell us about everything that happened with the tablet in lately. If you have dropped the device, they treated it, feared with him for the rain or donated to repair before - do not hide it. So the wizard will quickly understand the cause of the problem and can easier to eliminate it.

What to do to not repeat the problem?

Buy for a tablet a good case capable of protecting it from moisture and mechanical damage.
Contact the gadget gently.
Refuse cheap accessories. Repair is more expensive than you will save on "Unnamed" charging. It is better to take care of the original or high-quality China (say, Orico, Blitzwolf or Ugreen).
If the service center offers a replacement of the touchscreen, better insist on the installation of the original. Although we have all "for" and "against": maybe it will be more profitable to buy a new budget tablet every year?
Be sure! The problem with the touchscreen will not allow you to quickly save the data before repair.

e under android management. The touchscreen (sensor) works in itself, it works after a while after clicking, it is stupid, lags, it works not correctly. What to do and how to correct?

Many users face a problem when phone either tablet Na android database Begins to capricious. It seems not to fall there and not "watered" for nothing, but it does not work as it should.

For example, problems appeared in the device with touchscreen, i.e, the sensor input ("Sensor") works correctly. The reason why may be:

1st: Software failure - i.e. The problem is the software failure.

2nd: Hardware failure - i.e. The problem lies in the "hardware" (that is, it is required to replace or restore the spare parts of the gadget)

Next, from you, in principle, nothing more needs. The application will fully take control of the device functions. (By the way, in addition to all other things, the gadget will begin to charge 20% faster, and it will also significantly increase its productivity, which will reflect on the boot speed and work of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)

In addition, it is worth cleaning the system with a normal antivirus. Best, with this task copes kaspersky Anti-Virus , download which you can. Unlike the Multi-Cleener, the "Kaspersky laboratory" software is paid, because you do not have any opportunities to install such protection, this step can be skipped ...

Method 3.

Changing the software device, or, as it is also called "Pere firmware ".This methodAs a rule, requires certain skills and is solved by means of contacting the service center. To independently implement this task, you need to contact the manufacturer of your device, download the utility needs for the firmware and the firmware itself, after which reinstall it on your gadget.

If not one of the ways did not bring the results, unfortunately, you will have to contact Service center for repair and yours tablet A EY smartphone a.
