The iPhone display does not respond to touch. What to do if the sensor on your iPhone is not working properly? Replacing the iPhone touch cable is necessary every time one or more components dependent on it fail

Facebook

Happy smartphone owners from Apple They often contact service centers when the touchscreen on their mobile device breaks down. It could be like complete breakdown system, and partial, when the elements of the touchscreen on the iPhone do not respond well to the touch of a finger. In this article, we will look at what factors can lead to such a malfunction on the device, as well as why the sensor stopped working.

Easy to find on the Internet great amount forums where users ask questions:

“After the firmware, the sensor does not work. What to do?";
“What to do if the lower part of the sensor does not work.”;
“I dropped my iPhone, now the sensor on the phone is broken and does not respond well to touch . He's very dumb. How to fix?";
“What should I do if it doesn’t respond to touch?”

Reasons for this behavior mobile device can be very different. The touchscreen does not respond due to single or repeated mechanical damage. This could be due to a strong fall of the device or a hit against a hard object. Therefore, if you drop your iPhone, the touchscreen will not work and you will have to send it in for service.

Liquid

Sometimes the surface on the iPhone 6 does not work if liquid gets into the smartphone case. This problem needs to be addressed urgently as other systems may be added to the faulty display.

According to experts, part of the touch screen on the phone in the case when the module was replaced. The reason is incorrect installation or the use of a low-quality product.

If the screen does not respond to touch or only the lower part of the iPhone display does not function, then one of the reasons may be an internal failure of the system. Among them are:

Stopping the display matrix;
Stopping the functioning of the microcircuit inside the iPhone 5;
A short circuit, which occurred due to contamination of the device, caused it to break completely.

It is worth noting that like any operating system, iOS can be rebooted. This causes a number of problems, such as freezing. After this, the sensor triggers spontaneously, but at the same time it partially reacts to touch.

Viruses

Check your smartphone for viruses, as you may have installed an application, picture or music obtained from unverified sources. The information may contain viruses that cause malfunctions iPhone touchscreen 5s.

It may also be another intervention in the operating room. iOS system. Sometimes, after updating the firmware, the touch on the iPhone does not respond or begins to press itself due to the use of a modified version or incorrect operation.

How to fix the touchscreen

Most of those who know how to disassemble electronic devices, can check the operation of all its internal parts, for example, inspect the controller by opening the case. You can only find out the source of the problem, and then take preventive measures to prevent the breakdown from progressing. For example, if water gets inside, the sensor on the iPhone 5s begins to dull almost immediately. You can get rid of the problem by using a cotton swab to remove it, and also restore the functionality of some contacts. This measure will prevent a short circuit from occurring.

To begin with, we must say that there are two main types of screens on smartphones:

Resistive touch. This is a transparent membrane, under which there is a dense glass panel. They are coated with a special conductive resistive coating. If you touch the screen, its parts will short out, creating tension. This will allow microprocessors to automatically determine the location of the touch coordinate. This type of screen is not used in modern smartphones;
Capacitive screen. It is a full-fledged multi-touch that determines the location of the touch coordinate. It is used in the creation of smartphones from Apple. In order to repair it, you need to contact a technician at the service center in your city. Sometimes the sensor on an iPhone does not function, and interfering with the system on your own can lead to irreversible consequences.

Several working methods of repair

Let's consider several ways independent decision Problems:

If the sensor on your iPhone does not work, then first inspect the smartphone yourself for small cracks. In most cases they are the cause of failure. If you were able to find at least a few such traces, then you can be sure that the technician will replace the display. If the problem is serious, the controller may need to be replaced;
If the touchscreen lives its own life, try rebooting the phone. The normal reboot mode for an iPhone will not work; you need to use the emergency one. After turning off, hold down the Home button and the power button for 15 seconds. Such a radical reboot method can lead to the device starting to function again. You can also completely format your smartphone and return it to factory settings. Don’t forget to make copies of your documents in advance and place them in the “Cloud”;
If the touchscreen does not work correctly, as many users note, after removing the protective film or glass from the iPhone screen, work resumed in normal mode. The reason for this is dirt getting on the adhesive surface. This occurs in one case - when the protective material is not replaced in a timely manner. To prevent this, you need to remove the old film, wipe the screen of your mobile device and stick a new one;
If the touchscreen on iPhone 6 does not work, calibration helps. It can be done either using a specially built-in program, or using a downloaded one, for example, Zillow.

If after this the iPhone 5 does not respond to touch or the sensor on the phone begins to press itself, then the smartphone requires the intervention of a specialist. Often, the iPhone touchscreen controller requires repair, and doing such a procedure on your own is very dangerous.

“Prevention” against re-occurrence of failure

If a broken touchscreen has stopped responding to touch, then you need to take precautions. Constantly spending money on visiting service centers to fix the screen leads to high costs. In order to iPhone owner to prevent the touchscreen from breaking again, he must follow several rules that will reduce the risk of a problem occurring:

The device must not come into contact with moisture. Try to keep glasses and bottles away from him. Do not use your phone while swimming in a pool or your own bath;
Also, do not leave your phone in areas with high humidity, such as baths. Small particles of moisture enter the mobile device through micro-slits. This results in a short circuit;
Buy now special means protections that will cover everything possible places moisture penetration;
Protect your phone from mechanical impact. Regular bumpers, protective films, glass, as well as regular rubber phone cases help with this.

Video instruction

If your iPhone stops responding to touch, there are several repair options:

replace the entire module;

replace the touchscreen (to do this you need to disassemble the model).

However, there are cases when repairs as such are not required. Sometimes the sensor stops working due to a software glitch, or bad contact plume.

Contact may be lost after a fall, or as a result poor quality repairs V service center. It is impossible to find out the exact cause of the breakdown without disassembling the phone, so if you do not have the necessary skills, you should not deal with this problem yourself. Unless if there is a software failure, you can try to fix everything yourself by resetting the settings to factory settings.

You need to do a reset first. Very often this allows you to solve a problem with the performance of the sensor and avoid a trip to the service center. To reset the device to factory settings, connect it to your computer and perform a reset.

You can do it without connecting to a computer. To do this, press and hold the power and home keys. You need to keep the buttons pressed for 10-20 seconds. After this, the device will reboot. Before resetting, be sure to do backup copy your phone.

If the reset does not help, then you need to start disassembling. To do this you need to stock up necessary tool, including a star screwdriver, plastic spudgers for disassembling the case and a suction cup for the display. It's not difficult, watch the video on how to disassemble an iPhone.

It is necessary to remove the cover and check how well all the cables are connected. There are 3 cables coming from the display module. One responsible for the sensor, second for display image and third comes from the “Home” button.

Sometimes, after a fall, the cable flies out of its socket, and without good contact the sensor will not work. It is necessary to install the cable until it clicks and good contact should appear.

After checking the connection of the loop with motherboard check the functionality of the sensor. If everything works, then you can safely use the phone, but be prepared for the fact that if you fall, the problem may recur. If it is not possible to restore functionality, then it is necessary to change the sensor.

It is best to have your smartphone repaired at a service center. Having the necessary experience, you can repair your iPhone yourself. The easiest option for this is assembled.

In this case, you need to buy new module desired color, disassemble the smartphone and replace the damaged module with a new one. With such repairs, you don’t have to worry about further iPhone performance. Work new model should be no worse than a new phone.

More complex repairs will be required when replacing only the sensor. In this case, you will have to re-glue the sensor with complete disassembly module. In this case, it is very easy to damage working elements - cables, display and protective glass, which is easy to break when unsticking the module.

In some cases, neither replacing the entire module, nor repairing it, nor updating the smartphone firmware helps, for example, if it is damaged motherboard or image controller.

In this case, you can repair the phone only by re-soldering the controller or replacing the motherboard. It is better to carry out such repairs at a service center.

Before starting work, ask the technician to carry out diagnostics. Only after this will the real cause of problems with the touch screen become clear.

Apple monitors the quality of the parts from which its devices are assembled. Almost every element is improved in the new generation of devices, but no one is immune from defects or problems arising during operation. One of the most common problems with iPhone and iPad is sensor failure. The touchscreen may fail completely or partially, not responding to user touches across the entire surface of the screen or only in a certain area. If the sensor on your iPhone or iPad does not work, you should not immediately take the device to a service center; you can often solve the problem yourself.

Signs of a faulty iPhone sensor

On iPhone and iPad display module consists of three components: protective glass, display and sensor (touchscreen). Sensor malfunctions are manifested by the following symptoms:

The symptoms described above may be present constantly or may appear for a while, after which the iPhone will start working normally again.

enjoy touch device with a faulty touchscreen is impossible, and it is necessary to fix the problem immediately after it occurs. However, it is not always caused by incorrect operation of the sensor; in some cases, errors in touch processing occur at the software level.

What to do if the sensor on your iPhone is not working properly

If the touch handling issue is caused by software glitch, then the device user can eliminate it independently, without resorting to the help of specialists. To do this, you need to perform a “hard reboot” of the device by holding down the “Home” and “Power off/on the device” buttons simultaneously. After 15-20 seconds, the smartphone screen will go dark, after which it will light up apple icon- this means that the reboot was successful. After the iPhone boots up, you can test it for sensor performance.

In addition, if the sensor on your iPhone is not working well, you should make sure that the problem is not related to the case (or bumper) of the device. Often spontaneous clicks on the sensor are associated with improperly applied film to the screen. If there are errors in the operation of the touchscreen, it is better to remove all protective accessories and see how the sensor responds to touch without them.

iPhone sensor calibration

Apple does not provide calibration capabilities iPhone sensor or iPad users. There are no tools in the device settings that would be responsible for calibration, and only service center specialists can perform it, as stated in the official documentation for Apple smartphones and tablets.

At the same time, some touchscreen settings are provided in the iPhone, but they only apply to models older than the iPhone 6S and iPhone 6S Plus. We are talking about adjusting the sensitivity of the 3D Touch function. To adjust the pressure to perform various actions When using 3D Touch, you must do the following:

How to replace the touchscreen on iPhone

Replacing the sensor on an iPhone or iPad is a complex procedure that requires special skills, tools and a spare part. In most cases attempts self-replacement touchscreen in a smartphone leads to damage to other components of the device, cracks/scratches on the case and other problems. That's why it's better to trust Repair iPhone specialists from trusted service centers.

It is important to choose the right service center to replace the touchscreen, after reading reviews on the Internet. When contacting an unverified service, there is a high risk that a low-quality replacement sensor will be installed in your smartphone, which will quickly fail. Verified services provide a guarantee on the work performed to replace the touchscreen, which can be useful if the sensor starts to malfunction again.

The products of the American company Apple are of high quality. It fully justifies the prices at which the manufacturer offers its devices on the market. However, iPhone owners often encounter problems with the screen not working. Of course, a hail of questions immediately pours in about what to do if the sensor on the iPhone, or, as it is otherwise called, the touchscreen, does not work. Initially, we note that the display may either fail completely or cease to perform its functions partially.

Causes

Most often the reasons are mechanical in nature. It is clear that in this case some object must act on the display. It is not without reason that they say that it is better to purchase one for your device immediately after purchase and install it. If this is not provided, then be sure to stick protective film. Without additional protection, when dropped from a great height, the touchscreen of a fifth-generation iPhone, for example, stops working in 98 percent of cases. However, it is not excluded that the sensor does not work on the iPhone, software reason. That is, a failure within the operating system.

Manifestations

What signs clearly indicate that we have problems with the device’s sensor module? Probably, first of all, this should include the lack of response to touch in one or another area of the screen. Secondarily, this also includes a delay on touches, although in fact the response is still present.

A manifestation of the fact that the sensor on the iPhone does not work can be a complete disregard for all touches and simply refuses to process them. By the way, when problems arise with the touchscreen, this becomes a real source of problems for beginners just getting acquainted with Apple technology. So they start looking if the sensor doesn’t work. Another sign that clearly indicates the need for sensor repair is the random life of the device. That is, it can itself type a sequence of characters, applications open and close in the same way, and documents scroll through by themselves. A little creepy, if you think about horror films.

What to do and how to turn off the iPhone if the sensor does not work?

Let's imagine the following situation. Let's assume that the touchscreen of your device still functions, albeit with a large number of errors and inaccuracies. In this case we can decide this problem simple enough. To do this, we perform a complete reboot of the smartphone. To do this, follow simple instructions. The first step is to press two buttons at once. This is the power button, as well as a key called “To Desktop” or “Home”. They need to be held in this state for about twenty seconds. After this time, the device should begin rebooting. At the end, you will see the corporate logo of the American company, which will notify you that the reboot operation was performed correctly. By the way, this instruction is one of the answers to the question of what if the sensor does not work.

Check accessories

There are cases when they interfere with correct operation touch display. For example, if it was pasted incorrectly, it can contribute to this matter. In addition, there are now a huge number of undeniably cool bumpers for smartphones on the market, but not all of them are made well. If the bumper partially covers the display, it may prevent it from working properly. To check whether this is the reason, simply remove it from the device and use the touchscreen again a little. If normal operation will be restored, the problem is really in the bumper, and something will have to be done about it. If nothing has changed at all, then you need to move on and look for the reason for the incorrect functioning.

The answer to the question of how to restart an iPhone if the sensor does not work is quite simple. To do this, you need to use the appropriate key combination. Well, what to do next if the advice on rebooting the device did not help? What if the sensor continues to work incorrectly, or even does not respond to touches at all? In this case, everything is much more serious, and we are not dealing with a single failure, which, in fact, is just an exception to the rule, but with a technical malfunction.

In this case, you need to schedule and carry out a visit to the service center as quickly as possible, where specialists will inspect the screen and, if possible, return it to normal. Don’t let the question “The sensor on your iPhone doesn’t work, what should I do?” no longer torment you when even it doesn’t help? full reboot. Here we're talking about already about the need to act as quickly as possible so as not to aggravate the situation.

Why a service center?

If the sensor on your iPhone 5S or other device of this American company does not work, specialists with relevant experience will always be able to first recognize and identify the cause of the malfunction, and then localize and eradicate it. At the service center you can find out what condition the phone is in. If necessary, specialists will replace the screen on the device for an additional fee.

How long will it take?

Most often, replacing the display on an iPhone of any generation takes about one hour. There may be slight variations in both directions, but usually within an hour. One should not think that such a short period of work means their low quality.

If severe damage occurs

Screen deformation or even damage motherboard, which occurred as a result of high-intensity mechanical impact, will be the reason why you will need to part with your device for a longer period of time than an hour. Serious problems always require more thorough diagnosis. This is not just a sensor replacement, but a whole set of measures that together make up the single required for further correct operation complex.

The sensor cable is a flexible prefabricated part.
It first appeared on the iPhone 4 and is commonly called by the name of its main components - proximity and lighting sensors.

Like the top train, this assembly is constantly evolving.
With each new generation, some small revolution occurs here: one dependent part “moves”, another is added.

Replacing the iPhone touch cable is necessary every time one or more components dependent on it fail. It can be:

proximity and lighting sensors (iPhone 4-6 Plus);
noise-canceling microphone (iPhone 4-6 Plus);
front camera (iPhone 5-6 Plus);
connectors for the power button cable (iPhone 4/4S only);
connectors for connection auditory speaker(iPhone 4/4S only).

Replacement is carried out even if only one part is damaged, and all the remaining ones are intact. Reason: impossibility of resoldering the required component from a donor spare part (this is unreliable and uneconomical).

Damage to the sensor cable: typical cases

Corrosion. Moisture may leak through the speaker mesh, headphone jack (up to iPhone release 5 it was located in the upper part of the case, not far from the touch cable) or the dock connector. In 80% of cases, the part cannot be restored and must be replaced.

Physical damage. For example, if the phone hits the floor or any other hard surface. In this case, the risk of bending or damaging the cable increases if the touchscreen is damaged, since it is adjacent to the touch cable from the inside.

Replacing the iPhone touch cable: features and duration

The most difficult stage of the procedure is disconnecting, or rather, raising the screen module. To do this, you need to stock up on a special suction cup and patience (on the iPhone 5S, if the screen is separated carelessly and too sharply, the fingerprint scanner cable breaks). Then you need to disconnect the cables and cables running underneath from the motherboard. After installing the new touch cable, the phone is put back together.

During assembly, it is important to install the display module correctly, otherwise the sensor performance may decrease, and the proximity and light sensors will not work correctly.
