The sensor does not work on the iPhone: what to do? IPhone touchscreen does not work or works poorly - here is the fix Why the touchscreen does not work on iPhone 6

Often users of modern Apple smartphones are interested in what to do if the sensor on the iPhone is faulty, for example, after replacing the glass. And all because the entire operation 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 a software malfunction that you can fix 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 liquid for various phone models.

How to reboot your phone

If the touchscreen on an iPhone, after replacing the display or for some other 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 be one of the possible ways to restart your smartphone if the touchscreen does not work or any part of the iPhone sensor stops functioning

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 blocks the top or bottom of the display, it will interfere with the normal functioning of its module, and the screen will begin to glitch. To understand whether this is the reason why the touch screen does not respond, you need to remove the back cover and test the operation of the touch screen on the 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 did not produce results and, as before, the sensor is glitchy, or it does not respond to pressing, then most likely the problem lies not in a software glitch, but in a malfunction of the internal components of the phone and 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 carry out a high-quality replacement of the display screen.

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

The iPhone screen of any 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.

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, for no apparent reason, turn into “kiprichi” - the screen stops responding to touches. Most phones have long since expired, so it will not be possible to repair a “sick” iPhone 6 or 6 Plus at Apple service.

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 of the presentation of the iPhone 7, which is expected on September 7, i.e. two weeks later, 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 claims 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 “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. Every service center can repair the iPhone 6 screen.

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 iPhone's motherboard 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 service center, not to mention small workshops located in kiosks and basements, can handle such complex repairs using a microscope and a special soldering iron.

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 of Apple smartphones. The bend falls exactly where the touch screen controllers are soldered to the motherboard. The iPhone 6S and 6S Plus have a reinforced body, and this generation is free of the bending problem, as well as the “touch disease”.

“Over time, with the everyday use of a larger and thinner smartphone, sooner or later small cracks and micro-breaks in the solder joint appear between one of the controller chips and the 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 widens and, finally, one of the controller contacts comes 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 is to replace both touchscreen controller chips after cleaning the motherboard underneath them. The cost of such repairs corresponds to the operation of replacing the screen on an iPhone.

The warranty for the vast majority of iPhone 6 or 6 Plus has already expired, so the official Apple service will not help you for free. You will have to solve the screen problem using your own money.

Replacing the glass of an iPhone 5s, solving the problem of an iPhone 6 that has stopped responding to touches, an iPhone that is “bricked” due to error 53, entering the death date and a lot of other problems with Apple smartphones will be solved by repair specialists in trusted workshops. For example, in any case, repairing broken glass on an iPhone will have to be done at your own expense, because mechanical damage is not covered by the official Apple warranty, 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

The screen does not respond to your touch, the touchscreen becomes dull and freezes: remember if your phone has fallen recently? This may be the reason for the poorly functioning sensor on the iPhone 6, 6s.

In addition to the fall, the performance of the touchscreen is affected by:

• screen replacement;
• software update;
• moisture getting inside the device;
• screen dirty.

Experts believe that you should contact a service center if:

• the sensor responds, but with a delay;
• The phone’s “reaction” is missing in some places on the screen;
• The touchscreen doesn't work at all;
• The device lives its own life: it independently opens and closes applications, types text, and turns off.

Important! If the gadget does not respond completely to touch, then there is a possibility of a motherboard failure. It is necessary to urgently contact specialists.

What not to do and how to solve the problem yourself

In order to save money, advanced users want to fix gadget problems themselves. When trying to “reanimate” the touchscreen, you should not follow “harmful” advice:

• Dry your iPhone with a hairdryer if it falls into water;
• without outside help, glue or replace the screen if it comes off;
• disassemble and assemble the “mobile phone”;

This will increase the cost of repairs, but will not save the situation.

3 ways that you can take without being a specialist in the field of electrical repairs:

• Perform a complete reboot of the device (Press 2 buttons simultaneously for 20 seconds: power and home);
• remove the protective glass or film. They may be the reason why the sensor does not work on iPhone 6, 6s plus;
• Wipe the display from dust and dirt.

Important! Do not try to replace the screen on your iPhone yourself, because if you damage important parts, the repair will cost more. Only an experienced craftsman can perform such work. Our service center offersaffordable prices in St. Petersburg for iPhone 6 glass replacement.

Signs of malfunction

First, you need to figure out what problems arise when the sensor on an iPhone does not work. So, the malfunction manifests itself as follows:

• There are areas on the screen that do not respond to touch.
• The display does not respond to touch at all.
• After pressing, actions occur with a delay, or one touch causes several actions.
• So-called phantom clicks appear. Simply put, the phone begins to “live its own life.” So, certain applications can open/close independently, music can be turned on, calls can be made, and so on.

Please note that any, even one of these problems indicates that the sensor does not work on the iPhone. In this case, the situation may gradually worsen. For example, at first only certain areas on the display will stop responding to touch, and then the entire screen will begin to ignore touches.

Causes

Now it would be nice to find out what reasons lead to the occurrence of the malfunctions described above. This may happen:

• Due to mechanical damage. For example, your iPhone 5 fell and the sensor does not work after that.

• Under the influence of moisture. This does not mean that your phone should drown (although this can happen). So, after lying for some time in dampness (or in the rain), the device may begin to react inadequately to touches on the display.
• As a result of a manufacturing defect or the intervention of an unqualified employee of an iPhone repair shop.
• Due to software errors.
• When using certain accessories.

These, of course, are not all the reasons that can cause problems with the sensor. But, as statistics show, these cases are the most common.

This is worth doing first

As strange as it may sound, some accessories may be the reason why the sensor on an iPhone does not work. What to do in this case? Of course, remove all accessories and check how the device functions without them.

So, most often problems can arise due to a protective film, a bumper that partially covers the screen, various key fobs, cases, and so on. In any case, once you get rid of everything unnecessary, you will definitely make sure that the malfunction is not caused by accessories.

Troubleshooting a software glitch

Another common cause of problems with the sensor can be a software glitch. Fortunately, fixing it is not at all difficult. This is done using the so-called restart, which is performed as follows:

• Press the Home key and the power button of your device at the same time.

• Keep the buttons pressed for at least 20 seconds.
• Wait for the reboot.

If everything is done correctly, a standard logo should appear on the iPhone screen. After that, wait for some more time and check if the problem with the sensor is gone.

If resetting helps, but not for long

If the restart procedure described in the previous section helps, but after a certain time the sensor on the iPhone does not work again, then the reason should be looked for in the programs installed on your device. It is likely that one (or more) of the applications is interfering with the normal operation of the operating system and leading to all sorts of problems.

The best thing, of course, is to uninstall all third-party applications. After this, you need to restart again and check the functionality of the sensor. Then, if necessary, you can install the programs you need one at a time and test how they affect the behavior of the touchscreen.

Sensor calibration

Unfortunately, the developers did not provide the ability to fully calibrate the iPhone sensor at home. However, some settings are present in models 6S and above. Of course, we are talking about the 3D Touch function, which is responsible for the pressure required to perform various actions. To configure this option you need:

• Go to "Settings".
• Select the “Basic” section.
• Open the "Accessibility" tab.
• Click "3D Touch".

Now you need to move the slider, thus adjusting the sensitivity of the sensor. After this procedure, it is advisable to reboot the device.

Mechanical damage

It happens that none of the above manipulations helps and the sensor still does not work. In this case, the cause should be sought in mechanical damage. Please note that this is not necessarily a broken display. Thus, problems may arise due to deformation of the board, which can only be detected by employees of an iPhone repair service center.

Also keep in mind that repairing your smartphone at home is highly not recommended. Not only will you lose your warranty, but you also risk causing much more damage to your device than was originally the case.

Replacing the touchscreen

In most cases, the problem with a non-working sensor is solved by replacing the touchscreen. Again, it is best to do this at a specialized service center. There, by the way, you can find out how much a sensor for an iPhone costs, as well as how much the work of a specialist will cost you. Typically, the price of repairs depends on the model (the newer, the more expensive) and ranges from 1,000 to 40,000 rubles.

By the way, the operation to replace the touchscreen takes no more than an hour. At the same time, the quality of the work done does not suffer in any way from such speed. The fact is that problems with the display on iPhones are quite common, so technicians have already gotten the hang of quickly replacing damaged parts.

There are times when iPhone users experience a lack of response to touching the screen. This situation indicates a malfunction of the sensor (touchscreen). Before you try to resume normal operation of the phone, you should understand why the breakdown occurred.

Causes of malfunction

The sensor on the iPhone does not work for the following reasons:

• During the process of replacing the display module, not all cables were connected correctly;
• The phone fell face down, causing the screen to become unresponsive;
• Temporary OS freeze;
• Incorrectly installed updates. You may have turned off your phone while installing new firmware;
• Installation of programs incompatible with the device;
• The work of the virus. Some types of malware can block the touchscreen. While the user decides what to do, the virus opens the browser and advertisements on third-party resources;
• Using a non-original part. Fake display modules are not of high quality, so failure is a completely predictable phenomenon for such elements.

Degrees of touchscreen failure

In practice, there are different types of sensor failure in an iPhone. The failure may manifest itself as follows:

1. Only certain areas of the screen do not work. Here we can say with confidence that the reason is not a hardware failure. Most likely, the operating system is simply slow;
2. The touchscreen is completely unresponsive. The digitizer cannot process the touch and transmit it to the motherboard for further display;
3. The sensor stops responding after turning on a specific program;
4. The phone works fine, but periodically glitches and does not respond to touches;
5. The device randomly turns on programs, presses keys and opens unfamiliar sites. The reason for this strange behavior is the autoclicker virus.

We fix the problem ourselves

The problem is solved in the same way, regardless of the device model. First, try the simplest solution methods. Reboot your phone and the side buttons should work fine. If your phone is frozen, this will definitely help.

As a last resort, you can roll back the latest updates or reset the phone to its original settings (remember that all files and programs will be deleted, so it is better to first connect the non-working device to the computer and make a backup). Scan your device with an antivirus. Remove any Trojans found. If the sensor still clicks on its own, you should delete all browser data.

Do you have Zillow installed on your phone? This application does not work correctly with 5th and 6th generation iPhones. In the background, the utility can execute erroneous code, which leads to slowdowns. To resolve the issue, simply uninstall Zillow from your device.

If none of the above methods work for you, the problem lies in an incorrectly connected module. Perhaps the cables that secure the screen to the back cover were loosely connected.

Note! Very often, when turning off the touchscreen cable (shown in the figure below), users touch one of the filters with a spudger, which leads to its breakdown.

The filter is located at the bottom of the motherboard. The plug that hides it needs to be lightly removed with tweezers:

Most likely the filter has broken off. Part name – FL34. The markings are indicated in small print on the device board itself. This way you won't get lost in all the little details. All you need to do is ring the adjacent filter (FL35). If the 35th element rings, then the 34th filter can be easily replaced with a jumper.
