Android does not react to touch how to fix. Touchscreen does not work on a mobile phone: I read yourself

Components of electronic devices during negligent operation can break. If part of the touch screen does not work on the phone, it can be caused by both the temperature mode of use and mechanical damage.

Repair does not respond to touch screen smartphone or tablet will help competent diagnostics. Sometimes it helps the simple cleaning, combined with disassembling the case. However, if after all user actions, the device does not turn on, it will have to be in service, and this may lead to additional costs.

Causes of breakdown

You can select the following reasons why part of the screen does not work:

1. Oxidation of contacts due to condensate. Moisture, which turned out inside the device, can lead to a complete or partial loss of working capacity. The oxidized contacts cease to respond to processor commands and transmit them to the screen. To eliminate the consequences of fluid entering, you need to disassemble the device and clean internal components. To do this, you can use alcohol applied on a cotton wand or tampon. After this procedure, the phone should be turned on in normal mode.
2. Cracks on the screen surface. Because of the micro-tests of the sensor, it ceases to respond to pressing. There are such damage due to drops or shocks on the screen. Define cracks on the display can be carefully examined by its surface. If part of the touchscreen is covered with cracks, then it is possible to return efficiency using the device.
3. Turning off contacts of the touchscreen as a result of offset. Usually, the lower or top half of the screen does not work. To diagnose contact displacement, you need to disassemble the device and see whether the visual order of symmetry of the components is distinguished. If you see contact displacement, you can try to fix it with a tweezers. In addition, part of the elements is fixed on glue, which can be melted at high temperatures and move contact. In order for the top to be returned to the place, you need to heat the fastening with a hair dryer and return the component to its original position.

Features of operating electronic devices

In addition to the listed breakdowns, electronic devices May begin to work with failures due to the features of the internal architecture. The constraint of the size of the components affects the reduction of their power, if the tablet screen does not respond to touch - this may be a consequence of the device overload a large number of resource-intensive applications. For prevention, you need to start the task manager. Find out what is loaded cPU Devices, and disable extra applications.

Electronic devices have an increased sensitivity of the screen sensors. The situation when the screen of the tablet or phone does not work, can be associated with banal pollution. Putting fat and dust to the surface leads to the fact that the tablet does not react to the touch.

If the screen does not work on the tablet - the most better decision will attribute it to the diagnostics in the service center. For most models, there is a very long warranty that will allow additional cost to replace the device to another device without defects or return the money. If the case is not a warranty, it is possible to just buy a new gadget and subsequently more careful to it.

The display of the modern phone is not in vain called the most vulnerable component of the gadget. According to statistics, the most common reasons for repair mobile device It is a breakdown or incorrect operation of the sensor. At the same time, many users who do not understand the Touchscreen malfunction in the true reason, they independently try to disassemble the smartphone to pieces (which ultimately leads to the deplorable results) or give considerable money to repair.

In our article, we will answer the question why the phone sensor does not work: we give the main reasons and tell about how to act in each case.

The most common causes of the sensor breakage are:

Display pollution

Water getting inside the case

Oxidation of contacts

Incorrectly glued protective glass or film

Mechanical damage Sensor

Sharp drop temperature

Cleaning the cable of the matrix

Violations in work on

We will analyze every reason in order.

Cause 1. Display Contamination

If a oleophobic coating is not applied to the surface of the touchscreen, with the time the display is covered with fat stains, which become an interference to carry out the electrostatic signal from the fingers. At best, the sensor triggers each time, at worst - does not respond at all to the user's touch.

Decision

Cause 2. Water inside the case

If after a walk in the rain you found that the sensor does not work on the phone, most likely water got inside the housing. It is often possible to notice that the sensor stopped responding to touch after the smartphone was kept for some time in wet hands.

Decision

Seeing the smartphone, without disassembling it. The most affordable means will be a cup with rice, in which you need to put a smartphone for several hours. More information about all the ways of drying the phone can be found in the article "What to do if the phone fell into the water."

Cause 3. Oxidation of contacts

If, after drying the phone, the phone sensor did not fix it, perhaps the oxidation of contacts occurred due to moisture on them.

Decision

It will help accurate cleaning of contacts, preferably in the repair shop.

Cause 4. Incorrectly Claimed Screen Protection

When sticking protective glass Or film is very important to clearly follow the instructions. Otherwise, air bubbles can appear under the surface of the plastic or glass panel and the dirt can be accumulated. Because of this, the sensor loses sensitivity.

Decision

Carefully remove the film or glass from the screen and get a new defense. We recommend using our instructions in the article "How to stick a protective film on the phone."

Cause 5. Mechanical Damage Sensor

Perhaps the most common cause of the breakdown of the sensor - cracks, scratches or chips as a result of the fall of the smartphone. Also, very often the integrity of the touchscreen is broken due to the fact that the user carries a smartphone without a protective cover in his pocket with keys or coins.

Decision

Before fixing the sensor on the phone, it is important to determine the nature of damage. If the scratches are small, you can try to independently polish the smartphone screen. If there is sufficient knowledge and skills, the user will be able to replace the touchscreen without leaving the house. However, it should be remembered that any interference in the integrity of the smartphone can lead to even more serious breakdowns.

Therefore, the simplest and obvious decision, in this case, is repairs in the service workshop.

Cause 6. sharp temperature difference

Sometimes the phone sensor loses its sensitivity after a sharp temperature change occurred, for example, a smartphone with a frost has been made to a warm room, or vice versa. After that, Tatskrin reacts to touch once and not throughout its surface.

Decision

As a rule, the phone reboot helps. Also, after that it is recommended to wait a few minutes so that the temperature inside the gadget comes to normal.

Cause 7. Cleaning Matrix Clay

The smartphone screen, as a rule, is a peculiar sandwich from several layers. Touchpad It is placed on top of the matrix, which is attached to the phone with a loop. After falling the gadget on a solid surface very often, the screen does not receive external damage, but the sensor does not work. In this case, this means that the loop broke or departed.

Decision

Possessing the leased technical skills and special tools, like screwdrivers and soldering iron, you can connect a loop with a matrix or board. However, it is more reliable to produce this procedure in the service center.

Cause 8. Violations in work on

Even latest version operating system Android is not insured against program errors. As a result of the system failure, the screen is lit, but does not respond to the user's touch.

Decision

If the sensor does not work on the phone due to software errorTry to restart the smartphone. If it did not help, the most reliable way to restore the performance of the sensor is to attribute the smartphone to the service center. Of course, the system failure can be fixed through the flashing phone. However, it should be remembered that this procedure entails even more serious disorders in the work of the smartphone and the automatic output of the gadget from under service.

How to choose a smartphone to avoid a sensor breakdown

Of course, no modern gadget is insured from the breakdown of the touchscreen. Many users practically do not produce a smartphone out of hand throughout the day. Therefore, it is not surprising that various external and internal loads can lead to a sensor breakdown. But is it possible to minimize the risk of problems of the task of the touchscreen? Of course!

Last years, smartphones in a metal case with built-in protective glass are becoming increasingly popular. And the point here is far from spectacular appearance. In this case, the reliability of the gadget comes to first place. The metal case maintains more external loads, high-quality assembly helps to avoid the risk of moisture inwards inside the housing, and protective glass prevents scratches, due to which the sensor stops working.

Nevertheless, among users the opinion is very common that metal protected smartphones cost a lot of money. Especially if you do not want to make a discount on low power and performance.

However, on the current market of mobile phones there is a brand that tirelessly proves power, reliability, security and availability can easily be combined in one model. The British company Fly since 2003 steadily wins the recognition of users due to the combination of high technologies, bold design solutions, high-quality components and affordable prices in each model.

An extreme bright New Year of the summer of 2017 was the Smartphone Fly Selfie 1 - one of the most interesting in the technical and designer plan.

The thin and lightweight metal housing of the gadget is made of matted aluminum. This material is well conducted heat, so even during the active load, the phone sensor does not overheat. A bright and contrast 5.2-inch 2,5d IPS-screen is closed with high-strength glass Panda Glass, so the display is not terrible keys, lighters, coins and drops.

In addition, Fly Selfie 1 has absorbed such high-quality components as an excellent front and rear chamber - both on 13 megapixels; Powerful 4-core processor for 1.25 GHz, capacious lithium-polymer battery For 3000 mAh, fingerprint scanner and LTE 4G module.

Returning to the question of affordability, it is important to indicate that the price of a smartphone that looks and works, as a full premium flagship - only 8990 rubles!

Now you know why the sensor does not work on the phone, what to do in each case, and how to prevent possible breakdowns. It is easy to see that the most common solution to the problem with the sensor is repairs in the service center. Here it is important to specify Fly guarantees high-quality service of your phones and gives a year warranty on all models.

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

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)

However, do not rush to get upset - in 90% of cases with problems in the work of the touch input (touchscreen) smartphone and either tablet and on the basis of Android is to blame software failurewhich you can completely fix on your own.

Correct the program failure:

Method 1.Pretty simple - come in "Settings", find there « backup and reset "in which you choose full reset Settings with deleting all data.

The touchscreen (sensor) is bad in the phone or tablet running Android. 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?

Before trying to deal with what to do with a non-working touch screen, you need to deal with what happened. If this is not done on time, you can only worsen the situation. For example, if the problem lies in the wrong setting, the change of display and the matrix will not be solved the problem.

Why the screen does not react to touch

We will analyze several of the most popular causes of improper operation of the touch screen, as well as tell how to fix the current situation.

Display damage

Physical displays damage, probably, the most popular reason for the faulty operation of the touch screen, which has stopped responding to touch. Even a small drop or damage to the screen could lead to the fact that it will stop working correctly. There are also cases when someone sat on the phone or tablet, because of which the display was damaged.

In such situations, the replacement of the display is considered the most effective, as well as the repair of the entire screen, if it is damaged visually. Naturally, solve such problems yourself, changing the matrix or the entire display is entirely - the worst undertaking, especially if you have no experience.

As a result of such manipulations, it is possible not only to cancel the warranty that was on the technique initially, but also worsen the problem. Contact your service center, where you will be able to advise and provide full assistance.

Moisture hit

Most often, water that fell on the screen does not lead to sad consequences. Many users randomly overthrew the cup with tea or coffee, after which they quickly wiped the equipment, and she worked as if nothing had happened, but it happens not always. If the moisture was on the touch screen for too long, this can lead to sad consequences, for example, the damage to the display and the matrix - one of the most expensive parts in the tablet or smartphone.

The best solution in such a situation is to try to quickly dry the screen using for this that it can absorb moisture. Many users simply "merge" water from the screen, thinking that it works no worse, but such methods can lead to what the worst occurs.

Moisture can get under the screen, which will lead to more serious damage not only the screen, but also other components, such as motherboard.

Screen pollution

Too strong contamination of the screen may well cause it to stop working correctly. Dirt is capable of entering very deeply, which can lead to sad consequences. Despite this, quite often this problem can be solved by simple screen cleaning with wet disinfecting napkins. In addition, we recommend using such napkins from time to time so as not to lead to the screen breakage due to its contamination.

Incorrect setting

Due to the fact that most smartphones and tablets are provided to buyers already with a pre-installed operating system and all the settings, many readers could not know that the wrong screen setting could also become one of the reasons for his improper work. If you encountered it, you should not panic, because it is solved by several system programs. The most difficult for an inexperienced user can determine the source of the problem with incorrect setting. Even the debug mode does not always help, because the system menu is almost always arranged so as to work and without a touch screen, working exclusively from physical buttons Volume and nutrition. Therefore, if you encountered the fact that you just recently bought a smartphone or tablet, and the touch screen does not work on it, do not discard the reason incorrect setting Touchscreen.

Incorrect Screen Protection

Protective elements pasted on the screen, whether it is an extra glass or something like that, can harm the quality of the touch screen, if it is incorrectly placed on the display. If this work was carried out amators or people without great experience, After a while the sensor on your screen will stop working correctly, or it will not respond at all to the touch.

Determine the origins of the problem in this case is quite simple: you need to ask specialists to remove protection or do it yourself, if you can do it safely. Check the screen operation with protection and without it. After that, it will be enough to purchase better glass.

An excellent option will be a well-known model Gorilla Glass, which not only high quality protects the screen from any blows, scuffs or cracks, but also does not conflict with the sensor, thanks to which the problem with the sensitivity of the screen does not occur even with time.

Important: Be sure to ask specialists to stick to you the screen. Learn on the errors of others, and not on your own, because the incorrectly crucial protection on the screen can even lead to the fact that the display will be damaged.

Sharp drop temperature

Residents of the cold regions of Russia are probably familiar with a similar problem - a non-working touch screen after entering the street. Yes, maybe we are not often faced with a similar problem, but it is still often precisely temperature differences can affect the sensitivity of the touch screen. One of the most "peaceful" reasons, because to fix it, it is enough to have a little patience so that the display and specifically the touch (sensory part of the screen) is accustomed to temperature.

Be careful: no need to heat the screen with some special means, for example, a hair dryer or something like that. Strictly contraindicated to keep the phone screen over the heat source, such as open fire. Yes, maybe this advice will seem obvious for many, but experience shows that there are also users who want to do as better, but it turns out only worse.

Your attempts to artificially bring the screen from a cold state in hot only will be aggravated by the situation, without approaching you to normal operation Tacha. In addition, it can damage the inner component of the screen, which is why it can no longer work correctly.

Viral program

Malicious software is another reason, due to which the screen stops working. More precisely, the screen itself and the touchscreen works great, however, the blocker program does not allow the user to carry out the desired action. Certain this can be quite difficult without the help of specialists, as it is likely that to solve this issue will have to completely reinstall the operating system on the smartphone or completely reflash the phone. If you have not conducted such procedures before you, we recommend spending money on specialists who would help you.

You can catch the virus by downloading applications or music from unverified sources. If you use Play Market, then chances download fake application significantly decrease, but even in this case, be extremely attentive. To protect yourself from such applications, view reviews of those who have already downloaded this program or roller. If you use the new site, read about it on the forums to determine if it is possible to trust it by the safety of your device.

Cleaning the cable of the matrix

Have you tried to repair the screen yourself, disassembled the phone? A lot of beginners "technicians" have encountered this problem. Inappropriate repair of a small problem may well lead to a larger problem that will have to solve with the help of specialists, spending big money on them. If you want to quickly change something, saving at the same time on skillful hands, think if it is worth it. Most often for a small and simple work of the technique take a bit, but the breakdown of the loop may well lead to the fact that you have to change all motherboard Or overpass it, which will also be in a penny.

Do not think that if the cable of the matrix is \u200b\u200bdamaged, you will not be difficult to turn it on an ambulance hand. Service centers are always ready to provide their customers with qualified employees who will be able to securely repair techniques to the maximum short time.

Operating system failure after updating

Modern operating systems suffer from the fact that their new updates are not always stable, and can worsen the work of certain components in something. Although the problems associated with the touch screen rarely cause a failure in the operation of the operating system after the update, if this happens, you just need to return to previous version OS, which is often referred to as "stable".

Of course, it can be difficult to do this without a working touch screen, most of the devices support the connection of USB devices, such as mice or keyboard. If you have no OTG cable, which is an adapter between MicroUSB and USB, ask for help from specialists in technology stores. Most often, they are ready to provide their customers with this tool for a few minutes. You can always say that you want to test it before buying.

What to do

After the analysis of the most popular reasons, go to solve this problem. At the end of the list, the most effective methods Solutions, we give a small table, in which it will be shown what method to which problem is most suitable. If some of the reasons can not be attributed to any method, it means that their decision method was described above.

Full reset settings

If the problem did not damage the screen from the physical side, there is a high percentage of the likelihood that resetting the settings to the factory can fix the current problem. But how to do it on a standard Android device?

• We connect the mouse using OTG cable. As standard method The management of a smartphone or tablet does not suit us, you need to look for other methods for controlling the device.
• We go to the "Settings".
• Next - "Extended Settings".
• Go to the tab "Restore and Reset".

• I search for "Reset settings", which is most often located at the very bottom of the descent.

• We choose and confirm the changes.
• If necessary, do backup Data, however, if the problem lies in viral software, the reset of settings may not help.

Reset settings can be done through the engineering menu. In order to get into it, you need to press a special combination of physical keys at the time of starting the operating system (Volume and Power Buttons). Since it will be too long to list all models and stamps here, use the Internet to find how to get to the engineering menu on your phone. After that, select the desired item using the volume keys, confirming the choice using the power button. IN engineering Menu Looking for an item titled Factory Reset.which will reset all settings to factory.

Clearing Mobile Phone Screen

One of the most simple wayswhich can be done even with your own hands without the help of specialists. All that is needed to clean the screen of a mobile phone is special wet wipes that can be bought in machinery stores. Despite the fact that they are a bit more expensive than usual, they are much better clean the touch screens from dirt or something like that.

Cleaning should consist of two stages:

1. The main stage where you clean the screen from the mud with the napkins mentioned above
2. The second stage, during which you need to wipe the screen with disinfecting rags that are sold complete. It is necessary in order to remove moisture from your device. Cleaning the screen can be useful not only during the screen contamination, but also after moisture hit the screen.

Mobile Phone Screen Repair

Before repairing a mobile phone, make sure that the reason for the non-working touch screen lies precisely physically damage.
