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, you need to figure out what is the reason, and repair it - own forces 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:

• installation of low-quality software;
• electronics breakdowns;
• mechanical damage.

To conclude that the problem is in touchscreen, it is worth connecting to the device computer mouse. 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.

It can also be assumed that the warranty period of your device ended, otherwise the person would immediately appea to the service center.

What to do if the sensor does not work on the tablet?

Before deciding what to do if the sensor does not work on the tablet, you need to figure out the problem itself, that is, to diagnose the cause.

Causes due to which the sensor does not work:
• mechanical damage;
• fluid getting inside tablet.

Solution to the problem

Below, consider ways to solve the problem.

Display cleaning

So, first you need to simply clean the device display. It is possible that only the sensor plot reacts without letting you do any action. The same applies to those cases when the touchscreen on the tablet appears, it does not listen poorly and so on.

In some cases, it does not cover anything serious - the technique is characteristic of failure to fail for non-understandable reasons for users. Therefore, it is not necessary to immediately carry a gadget for repair: you can try to "reanimate" it at home. So, with what problems the device owner may 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

1. Display cleaning. Simple, banal, but often - a very good way. There are minor contaminants on the screen that prevent the sensor reaction or the protective film is pasted poorly. All this is easy to fix. The most reasonable to use a special lobby cloth (for example, microfiber) and liquid for cleaning monitors.
It will help to solve the problem of the sensor in case it hung "just so." If the keys do not work simultaneously with the screen, you must remove the battery (if such an opportunity is available), wait a few minutes and then turn on the tablet again.
2. Return to factory settings. Plates of different brands have its own features of Hard-Reset. In most cases, the simultaneous pressing of two keys is required - "home" and "volume increase", then "POWER" (screen lock button). The message will appear on the removal of information. After that, an automatic restart of the device will occur. But you need to remember that in contrast to the standard reboot of the tablet, this method Continuing the deletion of system information. But sometimes you do not have to choose. If you exercise this procedure in preventive purposes, it will be worthwhile to take care of creating a backup of available files. This method can help solve the problem of a non-operating sensor if the failure is caused by the virus. Also, there are also cases when the tablet's memory is overloaded, as a result, the device begins to hang, and the user erroneously connects the problem with the sensor problems.
3. "Emergency help". Touchscreen problems often arise through the fault of users. For example, if you were shed water to the device, you need to disassemble the gadget as soon as possible and dry. If the cause of the breakage was another liquid (juice, carbonated water or, even worse, gasoline - without the help of a specialist, it is unlikely to do without the help. Please note: put the tablet (or rather it is part of it) on the battery it is impossible to dry on the battery, too. One of The ways to solve this problem will be a "immersion" of parts in the rice cereal, which should collect extra moisture. It is not necessary to hurry here - try to include the tablet again recommended after 3-4 days, not earlier.
4. Replacing the sensor. Unfortunately, Tachskrin can give a failure without the possibility of returning it to the working state - no tablet is insured, regardless of its price category. There is a place to be both factory marriage and "secondary" caused by negligent operation of the device.

Buying a new sensor - the pleasure is not cheap. In addition to the fact that the price itself of the new sensor can reach up to half the cost of the tablet, it will be necessary to "fork out" and on the service of the master. But in some cases you can try to repair the gadget yourself.

On this topic, there are many visual video lessons on the network. In fact, replace the sensor is not so difficult. First you need to disassemble the tablet, pre-delete all the screws and other small details. It is important to memorize a sequence of device disassembly.

Next you need to disconnect the sensor. Most often he is attached to glue. In order to avoid damage to the device, high temperatures will need (about 60 ° C). Due to the lack of special devices, it is possible to use a hairdryer.

After disassembling all the details, make the internal "cleaning" of the device (if there is a need for this). Then attach the new sensor "in place" using a special double-sided tape or glue.

If repair at home is performed successfully, calibrate the touchscreen using the appropriate settings.

Screen Calibration Android

The calibration process includes the screen setting in order to perform the commands by the gadget by touching the sensor with your fingers or stylus. Without this setting, the product will work, but during operation, unwanted consequences appear, including the failure of the touch screen.

An "disobedience" of the touch screen may occur on Android. The touch system with a stylus or finger at a specific point of the sensor perceives as other commands. There are also situations when only after the 3rd or 4th attempt sensor performs the implemented commands. Often, the reason for these problems is related to the incorrect operation of the screen itself, so you need to calibrate the touchscreen of the device.

The correct and urgent calibration of the Android gadget may be required when the device accidentally fell into a water medium or from some height. Still the sensor calibration is needed after repair workrelated to the replacement of the screen, the occurrence under the glass of the water stain and after other transferred actions, even seemingly insignificant.

To verify the need for this procedure, the following steps:

• Remove the special protective film from the screen (to ensure the most accurate sensor operation).
• We enter any digit or letter.
• During the inconsistency, the button and displayed information is pressed on the device display, the touchscreen setting is required.

Main ways of calibration

To bring a shot down sensor to a normal position there are two ways:

• Application special applications for android systems.
• Independent adjustment.

It is important to remember that some calibration action brands almost do not differ from each other and are considered identical. Android gadget manufacturers can often apply 2 types of sensors:

• Capacitive - apply in most devices, they are more reliable and high-quality.
• Resistive - screens that are manufactured according to this technology are often broken, so the setting is more in demand. Similar screens are currently almost not used - these systems are only in budgetary or outdated models.

Screen Calibration with Android

If there is no access to the directory of the playing market, you can calibrate the device's screen can be with Android. Perform step-by-step instructions:

• Go to the device to the "Settings" section.
• Select the menu "Phone Settings".
• We find the item "Calibration, click on the button."
• The target-cross should be displayed on the screen inside which is the point.
• We click on this center formed target at least 3 times.

After implemented actions, the gadget independently makes memorization of the touches. It turns out that calibration can be considered completed. After the configuration procedure is completed, by the result of pressing certain characters on the screen, check the operation of the touchscreen.

Android Screen Calibration Applications

Sensor setting can be done using special applications. Free access has the necessary programs to produce calibration. Applications in the installation and work are simple, but the main thing is to obtain an efficient and positive result from the use of any of them. In the playing market you can find similar free Apps:
