The sensor does not work on the iPhone: what to do? IPhone touchscreen not working or not working well - here's the fix

Smartphones from Apple have always been distinguished by their safety and reliability in operation. But even the Cupertino company’s devices are not immune to “ordinary” breakdowns – battery, camera and touchscreen malfunctions.

Display problems occur for a variety of reasons. Some are corrected by actions with software part devices, others should be repaired by contacting a service center. Below we describe what to do if the sensor does not work on your iPhone.

To fix any display problems, you must first understand the cause. Most breakdowns occur due to mechanical impact on the phone case: a strong blow, fall or pressure. That is why, when purchasing a gadget, it is advisable to purchase a protective glass for the IPhone.

The sensor on an iPhone may also stop working as a result of a software component failure - in this case, most of the problems can be solved at home.

As stated above, faults can be divided into two categories: software and hardware.

Hardware

• Damage to the matrix after a fall or strong impact.
• Device overheating. In this case, only part of the display may not respond to touches.
• Wear of the touchscreen due to improper operating conditions or simple aging of the device.
• The use of non-original components when replacing already broken touchscreen. Cheap Chinese displays are usually no different high quality and a long lifespan.
• A disconnected or poorly connected matrix cable left after the work of an inexperienced technician.

Software

• Extreme load on the processor and RAM, which caused the smartphone to freeze. In such cases, the lock/volume switch buttons usually stop working.
• Malfunction operating system or problems with matrix drivers are very rare causes of problems.
• Infection of the device with malicious software.
• Incorrect actions when flashing or after performing Jailbreak. Apple gadgets especially often fail after interference with the operation of the OS.

Degrees of screen damage

Operational problems can be divided into several categories: in some situations the entire display fails, in others only part of it fails.

• Complete failure of the entire working surface of the screen.
• There is a response to touches, but only in certain areas of the touchscreen, for example, only at the top and bottom.
• Incorrect page scrolling in the browser.
• “Phantom clicks” is a malfunction in which a touch effect can occur just like that, without actually pressing the screen.

Software malfunctions

If the malfunction occurs regularly, you should perform a full reboot of the device. This procedure will help clear the RAM and accumulated “garbage” and reduce the load on the processor if too many applications have been running.

1. Press the Home and Lock buttons for 15-20 seconds.
2. The device will reboot. Turning on will take no longer than usual.

If this method does not help, try removing all unlicensed software from the device, if any. Pay special attention to recently installed programs. For example, the fifth and sixth iPhone generation Doesn't work well with the real estate app Zillow. The program executed code with errors in background, which led to general slowdown and freezes.

Old Apple models sometimes they may freeze or crash after updating to a new one IOS version. In such situations, only rolling back to previous version firmware.

We calibrate the sensor

In smartphones and Apple tablets There is no built-in sensor calibration function. The iPhone user manual states that this procedure can only be performed by specialists from branded service centers.

Some display settings are present in iPhone models newer than 6S and 6S Plus. In the device settings, you can adjust the sensitivity of the 3D Touch function.

1. Open iPhone settings.
2. Go to the “Basic” tab.
3. Click on the item " Universal Access”, followed by “3D Touch”.
4. Adjust 3D Touch sensitivity in the special menu.
5. Reboot your phone to save your settings.

Although 3D Touch is a fairly rare cause of problems, in some cases calibration can help get rid of freezes.

Mechanical damage to the touchscreen

After a fall or impact, the phone screen often breaks down. If the result of an “accident” with the device was only broken glass, the replacement will not be very expensive. But if the matrix is ​​damaged and the touchscreen does not process touches correctly, the cost of repairs will be considerable.

Important! Please contact authorized service centers for repairs only. Many “craftsmen” offer their services inexpensively, but then it turns out that instead broken screen a low-quality Chinese analogue was installed, and the technician “forgot” to connect the cable.

Cases when screen replacement is necessary

In most cases, you have to change the display on an iPhone after a hardware failure. Virus infection or congestion RAM can be eliminated at home or by paying for the services of a specialist.

Depending on your model and the degree of damage, the procedure will cost from several thousand rubles. “Masters” charge cheaper at bazaars, but if you don’t want to get new problems in the future, don’t use their services.

Change charger

An extremely rare phenomenon, but that makes it even more “disgusting” - charger creates interference on the electronic part and the touchpad refuses to work. This can only be overcome by purchasing a new charger, preferably an original one.

Avoid cheap Chinese no-name accessories!

Conclusion

Failure of the touch display occurs due to malfunctions in the software or hardware failure of the device. Warranty repair Only performed by service center specialists. Remember that after trying to repair your smartphone yourself, the manufacturer has the right to revoke your warranty.

Video

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.

Reasons

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 on a 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 cannot be ruled out that there is a software reason if the sensor does not work on the iPhone. 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 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 the correct operation of the 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 obstruct it normal operation. To check whether this is the reason, simply remove it from the device and use the touchscreen again a little. If normal operation is 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 life. 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 are talking 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.

Many owners of the “sixth” iPhone report broken screens on their devices. An epidemic of “touch disease” has engulfed Apple smartphones, repair specialists confirm reports from users. Expensive devices without visible reasons turn into “kiprichi” - the screen stops responding to touches. Most phones are out of warranty long ago, so get it repaired in Apple service A “sick” iPhone 6 or 6 Plus will not work.

A “touch disease” of the iPhone 6 and iPhone 6 Plus screens was discovered at the beginning of the year. Judging by the reports of repair engineers, it affects the touch screen controller chips of the device. As a result, the premium smartphone does not respond to screen taps. Accordingly, it is impossible to use iPhone 6 and iPhone 6 Plus with a broken screen.

The screen problem in the iPhone 6 does not appear immediately. First, the status bar turns gray and starts flashing. Then the touch screen of the smartphone stops responding to touches.

On the eve iPhone presentations 7, which is expected on September 7, i.e. in two weeks, iFixit, an independent service center for repairing smartphones and other mobile devices, published a detailed report on the problem of screens in the iPhone 6. iFixit says that “touch disease” is a widespread phenomenon, affecting thousands of smartphones.

“We don't know exactly how many iPhone 6s suffer from the screen issue, but every repairman we surveyed said the problem was very common,” iFixit reports.

“Almost every iPhone 6 and 6 Plus is a kind of “bomb” with a cocked clockwork mechanism. Sooner or later, such a “bomb” goes off, and the owner finds himself face to face with a useless smartphone, which not every workshop can repair,” says Jason Willmer, owner of the STS Telecom repair shop.

How to repair the screen on iPhone 6 and 6 Plus and cure it from “touch disease”

Repairing a brick iPhone is possible. In the service, you need to open the smartphone, carefully remove the broken touch screen controller chip and solder in a new one. Repair iPhone screen 6 can be far for each service center.

The repairman must have at his disposal special equipment for micro-soldering, and the operation itself will have to be carried out using a microscope, it is so delicate. A technician will have to remove the broken tiny chip from the motherboard. iPhone boards and replace it with a new one. The procedure is quite complicated. This is the only way to bring the damaged iPhone 6 back to life.

Not every serious person can handle such complex repairs using a microscope and a special soldering iron. service center, not to mention small workshops located in kiosks and basements.

Why does the touch screen stop working on iPhone 6 and 6 Plus?

Micro-soldering specialist Jessa Jones believes the “touch sickness” is the result of the same design flaw that led to the bent iPhone 6 and 6 Plus. Thin and wide smartphone cases bend more readily than previous generations Apple smartphones. The bend falls exactly where the touch screen controllers are soldered to the motherboard. In iPhone 6S and 6S Plus body strengthened, and this generation is freed from the problem of bending, as well as from the “sensory disease”.

“Over time, with everyday use more and more thin smartphone sooner or later small cracks and micro-breaks in the soldering appear between one of the controller chips and motherboard. So far the screen is working fine. However, later the owner notices that sometimes the screen does not respond to touches. After rebooting, the screen problem goes away. But the destructive process has already started and is not going to stop. The interruptions in the operation of the sensor become longer and longer, and the crack expands and, finally, one of the controller contacts breaks off from the main board. Any fall accelerates the development of the “disease.” Eventually, the screen on the iPhone 6 or 6 Plus becomes completely unresponsive to the user's touch,” explains Jessa Jones.

By pressing on the screen or trying to carefully twist the iPhone 6 in a horizontal plane, you can briefly bring the smartphone screen back to life. Heating the smartphone also helps, as it can reconnect the controller contacts that have been opened due to bending. However, such tricks can only serve as a temporary solution to the screen problem in the 6th iPhone. Sooner or later, the device’s display stops responding to touches.

Jones explains that the only reliable solution– replace both touch screen controller chips, after cleaning motherboard underneath them. The cost of such repairs corresponds to the operation of replacing the screen on an iPhone.

The vast majority of iPhone 6 or 6 Plus are already out of warranty, so... official service Apple won't help you for free. You will have to solve the screen problem at your own expense.

Replacement glass iPhone 5s, a solution to the problem of an iPhone 6 that has stopped responding to touches, a “bricked” iPhone due to error 53, entering a death date and a lot of other problems with apple smartphones Repair specialists in trusted workshops will help you decide. For example, repair broken glass In any case, iPhone will have to be carried out at your own expense, because for mechanical damage the official Apple warranty does not apply, even if the device was purchased literally a month ago.

Employees at Apple stores tell consumers that they are aware of touchscreen failures on the iPhone 6 and 6 Plus, but the company does not appear to officially acknowledge the existence of a “touch” disease.

Other news

Frequent users modern smartphones Apple companies are interested in what to do if the sensor on the iPhone fails, for example, after replacing the glass. And all because all the work of mobile devices with touch displays is directly related to the high sensitivity of the screen to pressure, with which you can use the gadget’s functions, view menus, and work with documents. If the sensor stops working, even after replacing the display, you lose the opportunity to fully realize your needs, which are often very necessary to fulfill.

Why does the sensor on a smartphone stop working?

The touchscreen on an iPhone can start to glitch completely spontaneously, for example, after replacing the display or if the smartphone has been dropped. As a rule, the reasons why the touch screen on a particular phone model does not respond to touch or the touch screen works intermittently are associated with mechanical damage to the device. To protect the display from impacts, you can install a protective glass on it or replace the film on it. Without additional protection, for example, if it falls, the touchscreen on the iPhone sometimes begins to freeze or completely fails.

Also, the reasons why the iPhone screen glitches and the touchscreen stops working are the following:

• liquid entering the device body
• crash after replacing software
• failure to comply with manufacturer's requirements when replacing display glass

If you are sure that the iPhone has not been dropped or water has been spilled on it, but it does not respond to touches, does not turn on, or does not respond correctly to presses, then most likely there is software failure, which you can eliminate yourself.

How does a malfunction of the display module manifest itself?

There are several signs that indicate that the sensor is faulty or the touchscreen on the iPhone is not working. These include the following:

• lack of sensor response to touches in a certain part of the screen
• ignoring any clicks on the display, which indicates that the sensor is lagging
• random operation of the gadget after it has been dropped or after replacing the glass (applications and documents open on their own)

Cleaning your smartphone screen

When starting to restore the functionality of a sensor that does not work well, freezes and slows down after replacing the glass or after you dropped it, you must first clean the display of your smartphone. You will not harm the phone in any way, but you will improve the connection, and perhaps the sensor will stop freezing and slowing down. This method will help if the display does not turn on, does not respond to touch, or the sensor periodically glitches.

If the sensor does not work well when buttons are pressed, and it often freezes or slows down, wipe the screen with a soft, lint-free cloth moistened with glass cleaning fluid various models phone.

How to reboot your phone

If the touchscreen on an iPhone, after replacing the display or for another reason, periodically freezes or the lower part of the sensor does not work, then you can fix the problem by rebooting the phone. When the sensor on your iPhone fails, do the following:

• Press and hold the power button and the Home key together for 20 seconds
• wait until the device restarts and the Apple logo appears on the display
• check if the sensor is working by touching any icon

This instruction will become one of possible ways how to restart a smartphone if the touchscreen does not work or any part stops functioning iPhone sensor

Check your accessories if your screen is frozen or won't turn on

There are situations when it is accessories that interfere with the normal operation of the display module and because of them, the iPhone screen of any model becomes dull and glitchy when buttons are pressed on it. For example, if the original protective film was glued to the glass incorrectly, the sensor stops working completely or becomes dull only in the lower part.

In addition, today you can buy any bumper for an iPhone, but not all of them can boast of high quality. If the bumper you purchased covers the top or bottom of the display, it will obstruct normal functioning its module, and the screen will start to glitch. To understand whether this is the reason why the touch screen does not respond, you need to remove back cover and test the operation of the touchscreen on your phone. If the problem is in the bumper, then the operation of the sensor, which sometimes freezes, will then be restored. If, after removing the accessory, the screen on the iPhone does not stop becoming dull and glitchy, then you need to further look for the cause of the malfunction of the display module.

What to do if the display module is frozen or does not work well

If rebooting the device does not produce results and, as before, the sensor is buggy, or it does not respond to pressing, then most likely the problem does not lie in software glitch, and if there is a malfunction of the internal components of the phone, you will have to replace the failed part. In this case, you should contact professional technicians who will diagnose the screen, determine the sensor malfunction and repair the phone.

If the keys periodically glitch and the sensor lags after you dropped the phone, or the display does not respond to pressing, a specialist will first determine the cause of the malfunction and then eliminate it. After diagnostics, the technician will tell you about the condition of the smartphone that was dropped or flooded with water, and why the sensor froze or did not work well. If required, he will quality replacement display screen.

In what cases will it be necessary to change the display?

Screen iPhone any The model is regularly exposed to various influences, which is why the touch screen may not respond to touches. Also, scratches on the display can cause the lower part of the sensor to not work. The solution to the problem when the entire screen or part of the iPhone sensor stops working is to replace the glass or install a new module.

You will have to change the display when the sensor malfunctions or displays information incorrectly in the following cases.

Some lucky iPhone owners sometimes have to deal with quite unpleasant problem– the sensor on the iPhone 5S is buggy. There can be many manifestations and reasons too. But, not the point, it’s more important to know what to do now.

Sometimes you can get by on our own, and in some especially difficult cases You can't do it without a trip to a repair shop. Therefore, in order to decide whether to take the device for repair or heroically save it yourself, you need to figure out what the problem is and what caused it.

So, the main signs of problems in touch screen iPhone:

• The screen does not respond to touch or only responds in certain areas. This may happen all the time or only occasionally;
• The response to touch occurs with a delay;
• The smartphone begins to live its own life: read Chinese blogs, call the Prince of Monaco, and also send vulgar SMS to friends, family and boss;
• Each manifestation has its own reasons, and, naturally, in order to troubleshoot, it is necessary to find out why it happened.

Why doesn't the touch screen work?

If the sensor does not respond to touch at all, this is likely due to mechanical damage, for example, due to a fall. This can also be caused by water penetrating inside the housing.

But it is possible that the problem lies with the OS, especially if the screen is only partially not working. The cause of an operating system glitch may be a simple failure/temporary freeze or an incorrect update.

Also, disconnection or malfunction of the sensor can cause specific program, usually downloaded from unknown source. And it doesn’t have to be “bad” - it just may be incompatible with current version axis or, in general, be outlawed by Apple developers.

If the iPhone 6 or 5c suddenly acquired artificial intelligence, and the “rebellion of the machines” took serious turns, then this is probably the work of a virus. Previously, there was no infection for mobile devices, but those days are long gone. Often this is the Autoclicker virus.

If the screen module has already been replaced, it is possible that it was installed incorrectly, something was damaged in the process, or it itself is of poor quality. There is no option - to take it back to the would-be master.

What else can affect the screen's performance?

• The screen matrix malfunctioned;
• One of the device parts has broken down, for example, the corresponding microcircuit;
• Internal contamination and resulting short circuit

In the latter cases, you cannot do without professional help, but in other cases there is a chance to cope on your own.

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

The very first step that works is to reboot the device. This applies to any electronics. In the case of an iPhone, you need to hold it for 10-15 seconds. Home buttons and inclusions. After this, the device will reboot, and perhaps everything will start working.

If it doesn’t help, then more radical methods will be required - a full return to factory settings or a rollback latest updates. In this case, all data will be cleared, so it is worth making a backup on your computer before starting this procedure.

It is also possible that dirt has gotten under the protective film of the screen, especially if it is glued poorly. Then you need to remove it, wipe it and stick a new one.

Sometimes, after a fall, protective glass microcracks appear, and air and moisture enter the space between the glass and the screen. An oxide film appears on the touchscreen, and it stops responding to commands or does it poorly. There are no options here - the glass is removed, the screen is wiped and a new protective surface is installed.

It could also be the bumper, which sometimes runs over the screen. Therefore, if everything works fine without it, the protective accessory needs to be replaced with a more suitable one.

As already mentioned, the operation of the axis can be affected by a certain program. For example, the Zillow application leads to similar consequences, especially on the iPhone 5S.

And finally, smartphones do not have a cooling system, so when the processor overheats, for example, on a hot summer day, a protection will be triggered that disables the control functionality. Here you just need to turn off the device and let it cool a little.

How to prevent it?

If all else fails, you will have to go to the nearest workshop. And there they will either make, probably, expensive repairs, or offer to replace the device with a new one.

Therefore, it is better to follow simple rules that will significantly reduce the risks of such breakdowns.

To do this you need:

Conclusion

In some cases, the suggested tips help, but it is safe to say that if the sensor has started to work intermittently, this will probably continue in the future.
