The screen on your smartphone does not respond well to touch. The touchscreen (sensor) on an Android phone or tablet does not work well

The wealth of options for using such devices leads to their gradual failure, and one of the common failure options is the dysfunction of the sensor on the phone, when the latter simply stops responding to presses (or reacts extremely poorly). In this article I will tell you what the reasons for this dysfunction are and what to do if the sensor on your phone does not work.

Finding out what to do when the touch screen stops working

Reasons for phone sensor failure

Let's look at common reasons why a phone's sensor fails. They may be as follows:

• Random malfunction of the device;
• On the gadget screen is a large number of dirt and grease;
• The protective film on the device screen does not fit tightly enough to the screen (air bubbles are visible between the screen and the film, dirt, etc.);
• The device has overheated due to various reasons, or has been subjected to a sudden temperature change;
• Moisture got inside the phone, which led to oxidation of the contacts;
• The sensor is physically damaged due to impact;
• The sensor has moved or peeled off;
• The SD card or SIM card is unstable;
• Some applications caused the device and sensor to freeze mobile device;
• The phone's memory is full, as a result of which the phone cannot correctly handle the touch screen;
• The internal components of the phone have failed (board, cable, etc.);
• Installation incorrect firmware phone led to problems with the sensor.

The sensor on the phone does not work - what to do?

Unlike push-button phones, in smartphones with touch screens the vast majority of functions are carried out through the display. Therefore, both the overall lifespan of the smartphone and its ability to function in principle depend on their durability.

Why might the sensor not work and how to fix the problem?

1. The touchscreen stops working.

Free legal advice:

If the touchscreen on your smartphone stops working, the reason is most likely due to overload random access memory device This means that you open a large number of applications at the same time, or force your smartphone to perform a large number of operations per unit of time. Because of this, there is a shortage of resources to process all processes, including taps on the screen, which is why it seems that the touch screen has stopped working.

Fix: Reboot your phone, preferably in safe mode, and don't load it any further to the point where the touchscreen stops working.

2. The display is dirty.

The main reasons for screen contamination are fingerprints, subcutaneous oil secretion, dirty or wet hands, exposure to environment(dirt, dust), etc.

Correction: wipe the touch screen, then use special screen protectors.

3. Exposure to too low or too high temperatures.

Free legal advice:

4. Damage or disconnection of the cable. This problem can occur as a result of shaking the smartphone, falling, impact, etc.

Correction: Contact the service center.

5. The phone falls or hits a hard surface.

Correction: Contact a service center for diagnosis, since a fall may cause several reasons why the touch screen has stopped working.

6. Spontaneous shutdown. This problem mainly manifests itself in poor quality budget models unpopular brands of smartphones.

Free legal advice:

7. Moisture gets inside the smartphone.

Fix: You can start by drying your phone with a hairdryer. If the problem persists, the contacts have probably oxidized and the smartphone needs cleaning. To do this, we also recommend contacting the service center specialists.

Correction: firmware. To do this you will need a cable and special software. If you have not done such things before, we recommend entrusting this work to professionals.

At many points, we recommend contacting a service center, since correcting errors, problems and failures in electronic devices, especially complex ones like smartphones, requires certain knowledge and skills. If you are ready to take full responsibility and risks for the performance of your smartphone, you can perform some procedures yourself, such as rebooting or flashing the firmware. Otherwise, we recommend that you contact our service center, where you will receive guaranteed quality service without unnecessary headaches.

Why doesn't the sensor on my phone work, doesn't work well, stopped working, part of the sensor

Modern people, keeping up with the times, have long managed to replace push-button phones on touch smartphones. Such devices are more practical and functional because they can simultaneously perform several tasks.

Once you decide to buy modern smartphone in the Fly brand store, ensure proper care of the device. Otherwise, you may encounter a problem such as malfunctions of the touchscreen (touch panel).

Why the sensor on the phone does not work: the main reasons

• Contamination of the screen surface: If you often handle your phone with dirty hands, fingerprints and greasy marks may remain on the screen, which reduces its sensitivity;
• improperly installed protective film;
• sudden changes in temperature can also briefly affect the ability of the smartphone to respond to your requests (for example, if you suddenly go outside from a warm room into the cold);
• damage to the screen or cable that provides connection to the touch surface due to a fall;
• phone software failure;
• the phone’s memory is full, as a result of which it is not able to process the owner’s requests;
• oxidation of contacts due to moisture getting inside the phone or the device falling into water.

Many of these reasons can cause a number of other malfunctions in the phone. For example, if a smartphone falls into water, problems may arise with the perception and reproduction of sounds, as well as with turning on. Find out what to do if your phone falls into water and does not turn on, so you can quickly solve the problem at home.

On our website you can find a catalog with other Fly smartphones on Android.

The sensor on the phone does not work: what to do to fix the problem?

Your actions in this situation will directly depend on the cause of such a failure. In some cases, you can solve the problem yourself and fairly quickly.

Free legal advice:

For example, if the touchscreen does not respond to your touch due to contamination of the surface, thoroughly wipe the screen using a special display cleaning fluid and a soft, clean cloth.

If the screen protector is not installed correctly on your phone, dust, dirt, and voids may form between the screen and the surface of the screen, making it difficult for your fingers to make contact with the sensor. It is enough just to replace protective film, having previously cleaned the screen of dirt.

If the sensor on your phone stops working after a fall, the reason may lie in cracks or damage to the cable. It is not worth fixing such a breakdown yourself. In most cases, the only effective solution is to replace the screen at a service center.

In some cases, the cause of malfunctions in the operation of the touch panel may be a software failure. You can solve this problem by flashing your smartphone.

If the sensor on your phone does not work for no obvious reason

If a sensor failure occurs suddenly, it is necessary to diagnose the phone and look for the exact causes of the failure. For this purpose, it is better to contact a service center. An experienced technician knows all the tricks of setting up Android and will be able to identify and eliminate the reason for the lack of response on the touch screen of your smartphone.

The sensor on the phone does not work: what to do

A touch screen device is functional and practical. Unfortunately, the reliability of such screens is low and the question of what to do if the sensor on your smartphone stops responding is very often asked on various forums.

Since the phone no longer has control buttons, all functions of the device are lost in one second. Troubles usually begin after the mobile phone is dropped or moisture gets inside, or it may stop working on its own, as happens with Chinese phones.

Reasons for the touchscreen not working

There are various reasons that can lead to such a malfunction:

The phone's memory is overloaded and the device does not have enough resources to process clicks.

How to reanimate a sensor at home

The very first thing to do is to restart the phone, while removing the battery and SIM card. Sometimes you need to reset your phone to factory settings. If a deep reboot does not help, then when taking further actions you need to understand all the risks and responsibilities.

In some phones, to get to the buttons you will need to disassemble the entire body of the device, and for this you need to study the sequence of disassembling the device. Without knowing this, there is a possibility of damaging the device, and the cost of repairs will be much more expensive.

Free legal advice:

Armed with special tools, carefully remove the touch screen. After this, you need to carefully inspect the cables and connectors. The operation of all functions of the device depends on their integrity. If there is no damage, then simply disconnect the display from the board and connect it back.

Since the phone has already been disassembled, carefully wipe the dirty contacts on the board with a cotton swab and alcohol and put the phone back together.

This clever way makes it easy to put it in place.

When all the screws are tightened and the assembly is complete, you can install the battery and turn on the phone.

If after all the manipulations no changes have occurred, and the touchscreen still does not work, then replacing the touch glass will help you. This is something that is extremely undesirable to do at home and you cannot do without a service center.

Phone Samsung s 7262, the screen was accidentally pressed, the sensor began to glitch, when entering words without touching the screen, it happens that he presses the letters himself, you have to turn the screen off and on

Hello everyone, there were similar problems with Samsung Gakaxy Tab 3, the phone tablet fell a lot and in fact the whole body looked like it had been bombed. Over time, the sensor began to fail, namely, when the processor overheated, the screen stopped responding; it worked, but did not respond to touches. I disassembled it at home, completely checked the processor myself and didn’t understand anything, but after reassembly everything worked fine. Yesterday, after an “accidental” hit on the screen, this problem arose again. I tried to solve it by blowing out the cable, blew it out, connected it, worked for several hours, and closed it in the morning. No matter how much I blew into it or picked at this cable, it didn’t matter to him, I had to peel off the screen and get to the screen chip. As it turned out, the blow was straight to this very chip. Another cable was connected there, I removed the film, took out the cable, inserted it back - it didn’t work. Well, I think that’s it, I’ll have to fork out more money, but I remembered that there was a video on YouTube where a guy doused the screen with electricity from a lighter so that some areas would return to working condition, I decided to try: I punched the main loop, it didn’t work, I punched the chip loop, it didn’t work, I shocked the chip, the sense came back. I’ll say right away: this may be a simple luck, and in your case it will not help, especially for those who have a non-removable panel, but often breaking through some elements saves the life of the equipment. Don’t repeat this on new phones, and especially on those that have a warranty, but for those who like to experiment and who don’t really need their device, go for it, maybe it can! All the best and cookies, maybe it helped someone.

I didn’t find the video, but the advice with the current helped) thank you.

Components electronic devices may break if used carelessly. If a part doesn't work touch screen on the phone, this could be caused by temperature conditions use and mechanical damage.

Competent diagnostics will help you repair a smartphone or tablet screen that does not respond to touch. Sometimes simple cleaning combined with disassembling the case helps. However, if after all the user’s actions the device does not turn on, it will have to be taken to the service, and this may lead to additional costs.

Causes of failure

There are the following reasons why part of the screen does not work:

1. Oxidation of contacts due to condensation. Moisture trapped inside the device can lead to complete or partial loss of functionality. Oxidized contacts stop responding to processor commands and transmitting them to the screen. To eliminate the consequences of liquid ingress, it is necessary to disassemble the device and clean it internal components. To do this, you can use alcohol applied to a cotton swab or swab. After this procedure, the phone should turn on in normal mode.
2. Cracks on the surface of the screen. Due to microdamage to the sensor, it stops responding to touches. Such damage occurs due to falls or impacts on the screen. You can identify cracks in the display by carefully examining its surface. If part of the touchscreen is covered with cracks, then it is possible to restore functionality using the device.
3. Disconnection of touchscreen contacts as a result of displacement. This usually results in the bottom or top half of the screen not working. To diagnose contact displacement, you need to disassemble the device and see if the visual order of the symmetry of the components is broken. If you see misalignment of the contacts, you can try to correct them using tweezers. In addition, some elements are fixed with glue, which can high temperatures melt and dislodge the contact. In order to top part returned to its place, you need to heat the mount with a hairdryer and return the component to its original position.

Features of the operation of electronic devices

In addition to the listed breakdowns, electronic devices may begin to malfunction due to the internal architecture. Limiting the size of components affects their power reduction if the tablet screen does not respond to touch - this may be a consequence of overloading the device with a large number of resource-intensive applications. For prevention, you need to start the task manager. Find out what is being loaded CPU devices, and disable unnecessary applications.

Electronic devices have increased sensitivity of screen sensors. A situation where the screen of a tablet or phone does not work may be due to simple contamination. The adhesion of grease and dust to the surface causes the tablet to not respond to touch.

If the screen on the tablet does not work, the most the best solution will take it to a service center for diagnostics. Most models have a very long warranty, which will allow you to replace the device with another device without defects or get your money back at no additional cost. If the case is not under warranty, perhaps you should just buy new gadget and subsequently treat it more carefully.

Video review of the causes of screen breakdowns

Devices with touch screens are functional and convenient, but their reliability is questionable. Occur frequently various problems with their use. Considering that mechanical buttons controls on modern devices have become rare; often the user completely loses control over the device.

Problems do not arise out of the blue; this usually happens after the smartphone is dropped or moisture gets inside it. What to do if the sensor does not work?

Why did the touchscreen fail?

Eat different reasons leading to device failure:

• Dirty display.

If your screen gets dirty for some reason, then a drop in sensor sensitivity will be a completely natural phenomenon. To deal with this problem, just thoroughly wipe the screen with a special napkin.

• Damage to the cable.

The element connecting the board and the touchscreen may have jumped out of the connector or been damaged. The problem will be solved if you open the device and carefully insert the cable into place. If there is no visible damage, try taking it to a service center.

• Moisture has entered the phone.

If water gets into your smartphone, oxidation occurs. In this situation, you can open it and carefully clean the contacts with alcohol. If your actions lead to nothing, take the gadget to specialists.

• Software glitch.

Sometimes problems arise with the firmware of the device, and you have to reflash it. To do this you will need a cable and the software itself. Usually this procedure is not difficult, just install the drivers and use the installation program.

How to change the touchscreen?

If the sensor no longer responds to your touch, and you have checked the cable and firmware, it’s time to use it effective method replacing the touchscreen. It doesn’t matter what exactly caused the breakdown, changing it is quite simple.

First comes the disassembly procedure. Remember everything you do, put the screws in a separate box so as not to lose them. There is a high chance that you will have to work with latches during the process.

When the device can be completely disassembled, remove the touchscreen. At this stage, it is important to pay attention to whether it has a monolithic screen or a touch panel. separate element. If the module is solid, then changing it is easy; in the case of a collapsible one, you will have to tinker a little.

If the matrix needs to be disconnected from the sensor, arm yourself with a regular hairdryer and warm up the display. Do this carefully, avoiding overheating. Then we disconnect it using some thin object. Then we glue the new touchscreen to the display. For this, glue is used, sometimes it is already applied to the purchased part.

Display modern phone It’s not for nothing that they call it the most vulnerable component of a gadget. According to statistics, the most common reason for repairing a mobile device is a breakdown or incorrect work sensor At the same time, many users, without understanding the true cause of the touchscreen malfunction, independently try to disassemble the smartphone into parts (which ultimately leads to disastrous results) or spend a lot of money on repairs.

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

The most common causes of sensor failure are:

Display dirty

Water getting inside the housing

Oxidation of contacts

Incorrectly pasted protective glass or film

Mechanical damage sensor

Sudden temperature change

Matrix cable failure

Software malfunctions

Let's look at each reason in order.

Reason 1: The display is dirty

If an oleophobic coating is not applied to the surface of the touch screen, the display will become covered over time. greasy spots, which interfere with the conduction of electrostatic signals from the fingers. In the best case, the sensor responds every other time, in the worst case, it does not respond to the user’s touch at all.

Solution

Reason 2: Water inside the case

If after a walk in the rain you find that the sensor on your phone is not working, most likely water has gotten inside the case. You can often notice that the sensor has stopped responding to touches after holding the smartphone in wet hands for some time.

Solution

Dry your smartphone WITHOUT DISASSEMBLY. The most accessible remedy would be a cup of rice, in which you need to put your smartphone for several hours. You can read more about all the ways to dry your phone in the article “What to do if your phone falls into water.”

Reason 3. Oxidation of contacts

If after drying the phone the phone sensor is not repaired, the contacts may have oxidized due to moisture getting on them.

Solution

Careful cleaning of the contacts, preferably in a repair shop, will help.

Reason 4. Incorrectly applied screen protector

When gluing protective glass or film, it is very important to strictly follow the instructions. Otherwise, air bubbles and dirt may accumulate under the surface of the plastic or glass panel. Because of this, the sensor loses sensitivity.

Solution

Carefully remove the film or glass from the screen and stick new protection. We recommend using our instructions in the article “How to apply a protective film to your phone.”

Reason 5. Mechanical damage to the sensor

Perhaps the most common reason for sensor failure is cracks, scratches or chips as a result of dropping the smartphone. Also, very often the integrity of the touchscreen is violated due to the fact that the user carries the smartphone without protective cover in your pocket with keys or coins.

Solution

Before you repair the sensor on your phone, it is important to determine the nature of the damage. If the scratches are small, you can try polishing the smartphone screen yourself. If you have sufficient knowledge and skills, the user will be able to replace the touchscreen without leaving home. However, it should be remembered that any interference with the integrity of the smartphone can lead to even more serious damage.

Therefore, the simplest and most obvious solution is in this case- repairs in a service workshop.

Reason 6. Sudden temperature change

Sometimes a phone’s sensor loses its sensitivity after a sudden change in temperature occurs, for example, a smartphone is brought from a cold place into a warm room, or vice versa. After this, the touchscreen reacts to touches every once in a while and not over its entire surface.

Solution

As a rule, rebooting the phone helps. It is also recommended to wait a few minutes after this for the temperature inside the gadget to return to normal.

Reason 7. Matrix cable failure

A smartphone screen, as a rule, is a kind of sandwich of several layers. Touchpad is placed on top of the matrix, which is attached to the phone board with a ribbon cable. After a gadget falls onto a hard surface, very often the screen does not receive external damage, but the sensor does not work. In this case, it means that the cable has broken or come loose.

Solution

With advanced technical skills and special tools, such as screwdrivers and a soldering iron, you can connect the cable to the matrix or board. However, it is most reliable to carry out this procedure at a service center.

Reason 8. Software malfunctions

Even latest version operating system Android is not immune to software errors. As a result of a system failure, the screen lights up, but does not respond to user touches.

Solution

If the sensor on your phone does not work due to software error, try restarting your smartphone. If this doesn't help, most reliable way To restore the functionality of the sensor - take the smartphone to a service center. Certainly, system failure can be fixed by flashing the phone. However, it should be remembered that this procedure entails even more serious violations in the operation of the smartphone and automatic removal of the gadget from service.

How to choose a smartphone to avoid sensor damage

Of course not one modern gadget is not insured against touchscreen failure. Many users practically do not let go of their smartphone throughout the day. Therefore, it is not surprising that various external and internal loads can lead to sensor failure. But is it possible to minimize the risk of touchscreen malfunction? Of course!

In recent years, smartphones in a metal case with built-in protective glass on the screen have become increasingly popular. And the point here is far from being spectacular. appearance. In this case, the reliability of the gadget comes first. The metal case can withstand more external loads, high-quality assembly helps to avoid the risk of moisture getting inside the case, and the protective glass prevents scratches, due to which the sensor stops working.

However, there is a very widespread belief among users that metal rugged smartphones cost a lot of money. Especially if you don’t want to make allowances for reduced power and performance.

However, on modern market mobile phones There is a brand that tirelessly proves that power, reliability, safety and affordability can easily be combined in one model. The British company Fly has been steadily gaining user recognition since 2003 thanks to its combination high technology, bold design solutions, quality components and affordable prices in each model.

The most striking new product of the summer of 2017 was the Fly Selfie 1 smartphone - one of the most interesting in technical and design terms.

The thin and light metal body of the gadget is made of brushed aluminum. This material conducts heat well, so even during active load the phone's sensor will not overheat. The bright and contrasting 5.2-inch 2.5D IPS screen is covered with high-strength Panda Glass, so the display is resistant to keys, lighters, coins and falls.

In addition, Fly Selfie 1 incorporates such high-quality components as an excellent front and rear camera - both 13 megapixels; powerful 4-core processor at 1.25 GHz, capacious lithium polymer battery 3000 mAh, fingerprint scanner and LTE 4G module.

Returning to the question of affordability, it is important to point out that the price of a smartphone that looks and works like a full-fledged premium flagship is only 8,990 rubles!

Now you know why the sensor on your phone does not work, what to do in each case, and how to prevent possible breakdowns. It is easy to see that the most common solution to a sensor problem is repair at a service center. It is important to point out here that Fly guarantees high-quality service for its phones and provides a one-year warranty on all models. You can find out the location of the service center in your city on the brand’s official website.
