Part of the touch screen does not respond to touch. Simple tips for those whose phone sensor does not work. Reasons for phone sensor failure

Modern gadgets have become an integral part of our lives. The telephone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water or software glitches. The most common problem that many mobile device users face is that the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact service center. Otherwise, there is no need to rush, because there are cases when the problem can be easily and quickly fixed. The sensor does not respond to touch, what should I do in this case? Let's look at all aspects of this problem.

Phone screen repair

Before solving the problem, you need to make sure what is causing your display to break down. This could be mechanical damage, liquid getting inside the device, or software glitch. If you are sure that you did not drop the phone or spill liquid on it, then we can assume that this is a software glitch.

Cleaning your mobile phone screen

First, you can simply clean the display of your device. You will not harm the phone in any way, but improve the connection and perhaps the problem will be solved. This method may help if the sensor does not respond to touch. What to do?

Take a suitable cloth and liquid to clean the screen. It is better to use lint-free or any other natural fabric. To clean the display, we will need a glass or monitor cleaner.

If this method does not help, then you should move on to the next steps. Of course, they may not help either. Only a professional can determine the true cause of the breakdown, but even he cannot solve every problem.

Software glitch that caused the display to break

If the display mobile device sometimes reacts to your touch, then you can try making it Hard Reset system, This full reset settings. But it’s worth remembering that this can only help if the sensor glitches from time to time. After resetting the settings, install applications that can clean system registry. This will eliminate errors caused by RAM. Recommended applications are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but has good functionality. The first program is suitable for you if you are not sure of the reason why the display does not respond well to touch, and you are not going to spend money.

All actions should be performed without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card in place and scan the device with an antivirus. Select full check devices and wait. But even after these actions, the sensor does not respond to touch. What to do? In this case, it is necessary to proceed to replacing the sensor, since the reason is not caused by a software failure.

Mobile phone display replacement

The sensor does not respond to touch - what should I do? If previous methods did not help, then you need to replace the damaged display. Most often, this needs to be done when the device has been dropped, cracks have appeared, or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. Thus, condensation that accumulates in a mobile device will interfere with normal operation phone. At first, black spots may appear when working with the gadget, and later the sensor itself will stop responding to touches. In this case, you will need to change the screen.

Phone screen repair - not too much difficult process, the main thing is attentiveness and accuracy. Any person can do this. The sensor does not respond to touch - what should I do? First you need to disassemble your device, but you should remember the sequence of actions so that there are no problems with assembly in the future. All plugs and latches are removed using a thin object. You will need to carefully remove all elements from the latches with this object.

After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, since when ordering a new screen, this aspect will need to be specified.

The sensor can also be connected to printed circuit board different ways. Exists contact method, in this case the sensor is simply disconnected and is wired. In the latter case, you should be very careful.

If you need to detach the matrix from the sensor, you must follow these recommendations:

First, heat the surface to 60 degrees. This can be done using a regular hair dryer. It should be heated evenly so that the glass does not crack and the glue heats up.
Next, you need to find a flat and thin object to easily disconnect the sensor from the matrix. To do this, simply pry the edges and carefully lift them up.

All that remains is to attach the new sensor. How to do it? The kit should include the sensor itself and glue. First we apply special glue, and then carefully attach the sensor.

Cost of a new display

How much does it cost? Of course different models For smartphones, the cost of the screen will vary. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, you will need to pay about 700 rubles.

If you don’t want to disassemble the phone yourself, you can contact a specialist. The master will ask about 2000 rubles. Although this procedure is not very complicated and you can change the screen yourself. You just need to approach this carefully and carefully.

Touch buttons don't work

Lower touch buttons directly relate to the screen and in the event of their failure, it is necessary to perform all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clean the system registry and scan your device for viruses. Unfortunately, if the steps taken do not help, you will need to change the screen.

Modern mobile devices cannot be imagined without touch screens. Therefore, it is necessary to decide what to do if the sensor on your phone does not work only after studying the events that led to the breakdown. The screen is the main part of modern smartphones, without which they lose all functionality.

In order to find out why the sensor on your phone does not work, you will need to carefully examine your smartphone. Sometimes problems in the phone are visible to the naked eye, for example, if the screen is broken, and in some cases the functionality may be lost for no reason. Moisture ingress, rough mechanical impact and much more can affect the serviceability of the device.
If the source lies in a software glitch, then a situation may occur where the gadget does not respond correctly to your touch. Such problems often arise due to the actions of the owner himself, who, through negligence or inexperience, made changes to the operation of the system.

Common touch screen problems

Most common cause The reason why the touchscreen does not work is mechanical damage. Impacts and other impacts can lead to negative consequences. The most neutral will be chips; more serious problems will appear when a “cobweb” forms, in which the device can continue to function.

Because modern smartphones Since the device is quite fragile, even after falling from a height of human height, it stops working. If the device continues to function, and the damage is caused in the form of the formation of cracks in the case or its deformation, or the cessation of operation of part of the screen, then it is necessary to short time contact a specialist for repair work.

Another popular cause is moisture ingress. Despite the fact that the device looks like a monolithic device, it has small cracks and gaps through which liquid gets onto the main board.

Moisture and liquid entering the phone body

Moisture entering a cell phone leads to the beginning of the oxidation process of the contacts and the board. If the gadget gets into similar situation, then you shouldn’t disassemble your smartphone unless absolutely necessary. The first thing you need to do is dry the device. If drying does not produce results, then it is worth taking it to a specialized repair center, which is especially true for expensive models, intervention in internal circuit which leads to irreversible consequences. During repairs, you can use a cheap replacement device that will receive calls and SMS.

Oxide Elimination

In some cases, after moisture gets inside the gadget, through certain time it will start to work, but poorly or incorrectly. In this case, you can try to independently eliminate the oxide that appears upon contact with the liquid.

To do this, you will need a tool with which to remove the oxide (a plastic card, a screwdriver, and so on). Also needed: alcohol, toothbrush, eraser and napkins. Before disassembling your smartphone, you need to read the instructions, which can be found on the Internet.

The cleaning procedure must be carried out carefully, as any awkward movement can lead to additional damage. The disassembled gadget must be folded onto a sheet or napkin so that it can be easily assembled, as per the drawing. Each place should be wiped with alcohol, an eraser and blotted with a dry cloth.

If traces of rust are found, it is removed with a toothbrush. The area is treated with alcohol, the remaining corrosion is removed with an eraser.

It will be especially difficult in cases where the cause is a sweet drink. Exposure to such a mixture has a chance of damaging the gadget, and without the intervention of a specialist, repair will be impossible.

Stained display

If the display becomes dirty without damaging the screen, then you just need to thoroughly wipe the sensor with cleaning fluid, and then remove the remaining moisture with a dry cloth. To save the display, it is recommended to use protective film, which is easily glued and removed in case of contamination.

Damage to the cable

Damage to the device cable is one of those causes of breakdown that cannot be fixed at home. Therefore, if the sensor sometimes does not work correctly, you should contact a specialist who can restore the device’s functionality with a guarantee.

Software glitch

Reboot your smartphone. In some cases, changed software operation settings will not be applied after a system reboot.
Use the built-in sensor testing program. To do this, you need to enter a combination that is unique to the device of each brand.
Check the temperature of the device and place the device in favorable conditions.
Check the operation of the memory card and SIM card.
Boot the gadget in safe mode.

In some cases, the problem can be solved by these in simple ways. If your attempts have not yielded any fruit, then you should contact the experts.

For changing push-button phones Touch devices have arrived. What has changed since this technology became firmly established in our lives? Almost everything that is in any way related to the functioning of the device. That is why a situation in which the sensor stops working requires immediate resolution.

These shortcomings are, in principle, conditional and can be easily avoided. We can seriously say that a person is the most important factor in the performance of a mobile device. It is the actions of the owner that will determine how long the device will be in use and why the sensor on the phone does not work.

Common touch screen problems

Often, breakdowns occur due to mechanical damage. If the phone is dropped or deformed, the device will not function properly as a result. Impacts or other mechanical influences can cause various consequences. As a rule, they can be ordinary chips on the lid in best case scenario or a cracked display - at worst. If the deformation of the case does not affect the operation of the gadget in most cases, then the screen will need to be replaced. If the sensor stops working, then you need to pay attention to the components of the mobile device. If the case part moves slightly away from the display and you can notice a gap, then you should immediately take the phone in for repair.

Sometimes a smartphone may stop working if liquid gets into it. Many people have absolutely no idea how water manages to get on the board, but this is a common problem.

Self-rehabilitation

If the sensor on your phone does not work, it is not clear what to do, then first you need to go to the device settings. There you need to calibrate the touchscreen. This feature can often be found in the main settings. These steps can be carried out if the screen is completely in order, the body is intact, and there are no signs of deformation or oxidation. If the sensor has a perfectly smooth surface, then it is likely that the touchscreen has simply turned off.

If the forecasts are not entirely optimistic, the sensor on the phone still does not work, what should I do? It is better to immediately start looking for a solution to your problem. In order to commit the following actions, you need to have certain skills.

Oxide Elimination

All accessible places where liquid can get into should be wiped with alcohol, then with an eraser and then blotted with a napkin.

In order to eliminate corrosion of the board, you need to use a toothbrush. Often this is the reason why the phone’s sensor has failed. Where the connection of loops occurs, especially if we're talking about about the connector touch screen, it is necessary to treat with alcohol and remove plaque with an eraser. As a result, the surface will be dry and clean.

If the screen peels off or shifts, then this is probably the problem. Often in such cases the phone’s sensor fails. To put the screen in place, you need to use a hairdryer. You can peel off the touchscreen from the display simply by heating it. The glue will dry, and then it will be easy to move the sensor to the desired location.

The device must be assembled carefully and carefully, installation must be done one at a time. Don't forget about screwing in the screws. It is also necessary to put protective housings back on the microcircuits.

Other methods: how to fix the problem

There are many other reasons why a sensor can fail, so a person’s actions will directly depend on the failure. Sometimes you can solve this problem yourself, remembering that the repair touch phones- an expensive service. For example, if the sensor does not work due to surface contamination and does not respond to touch, then you need to wipe the screen with liquid. You should also use a soft cloth. This is necessary if the question arises about what to do - the sensor on the phone does not work.

If the protective film was installed incorrectly and now the lower part of the sensor on the phone does not work, you need to replace this coating by cleaning the screen from dirt. Dust and dirt often get trapped under the film. This is what makes working with the sensor difficult.

In other cases, the cause may be a failure software. This problem can be easily solved by resetting the settings or flashing the device. In the most in case of emergency should contact the service center. We'll talk about this below.
