The sensor on the iPhone does not work: causes, diagnostics, repair. Why is the touch screen not working? What to do if the sensor on the iPhone is not working

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, it is not uncommon for iPhone owners to face problems related to a non-working screen. Of course, a hail of questions immediately pours in about what to do if the sensor does not work on the iPhone, or, as it is called otherwise, the touchscreen. Initially, we note that the display may either fail completely or cease to perform its functions partially.

The reasons

Most often, the reasons due to which they are mechanical in nature. It is clear that in this case some object must act on the display. No wonder they say that it is better for your device to purchase immediately after purchase and install it. If this is not provided, then be sure to stick a protective film. Without additional protection, when dropped from a great height, the fifth-generation iPhone touchscreen, for example, stops working in 98 percent of cases. However, it is not excluded if the sensor does not work on the iPhone, software reason. That is a failure inside operating system.

Manifestations

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

A manifestation of the fact that the sensor does not work on the iPhone can be a complete disregard for all touches and simply refuses to process them. By the way, when there are problems with the touchscreen, it becomes a real source of problems for beginners who are just getting acquainted with the “apple” technology. So they start looking if the sensor does not work. Another sign that clearly indicates the need for sensor repair is the arbitrary life of the device. That is, it itself can type a sequence of characters, applications open and close in the same way, and documents scroll through on their own. 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 such a case, we can decide this problem simple enough. To do this, we perform a complete reboot of the smartphone. To do this, follow the simple instructions. The first step is to press two buttons at once. This is the power button, as well as the key, which is called “To the desktop”, or “Home”. In this state, they need to be held for about twenty seconds. After this time, the device should reboot. At the end, you will see the corporate logo of the American company, which will notify you that it performed the reboot operation correctly. By the way, this instruction is one of the answers to the question of how if the sensor does not work.

Check accessories

There are times when they interfere with correct operation touch screen. For example, if it was pasted incorrectly, it can contribute to this matter. In addition, there are now on the market great amount undeniably cool smartphone bumpers, but not all of them are made soundly. If the bumper partially covers the display, it may interfere with its normal operation. To check if this is the reason, simply remove it from the device and again use the touchscreen a little. If a normal work will be restored, it's really in the bumper, and something will have to be done about it. If nothing has changed at all, then you need to go further and look for the cause of 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 tips for rebooting the device did not help? What if the sensor continues to work incorrectly, or even does not respond to touch 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 soon as possible, where specialists will inspect the screen and, if possible, return it to normal life. Let the question “The sensor does not work on the iPhone, what should I do?” No longer torment you, when it doesn’t even help full reboot. Here we are already talking about the fact that you need to act as quickly as possible so as not to aggravate the situation.

Why Service Center?

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

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 system board, which occurred as a result of a mechanical impact of high intensity, will be the reason due to which you will need to part with your device for a longer period of time than for an hour. Serious problems always require more thorough diagnosis. After all, 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.

Some happy iPhone owners sometimes have to deal with a rather unpleasant problem - the sensor on the iPhone 5S is buggy. There can be many manifestations and reasons too. But, not the essence of the matter, it is more important to know what to do now.

Sometimes you can do it on your own, and in some particularly difficult cases, you can’t do without going to the repair shop. Therefore, in order to decide whether to carry the device for repair or heroically save it on your own, you need to figure out what the problem is and what caused it.

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

• The screen does not respond to touch or only responds in certain areas. This may happen all the time or only from time to time;
• The touch response is delayed;
• The smartphone begins to live its own life: read Chinese blogs, call the Prince of Monaco, and send vulgar SMS to friends, family and boss;
• There are causes for every manifestation, and naturally, in order to troubleshoot, it is necessary to find out why it happened.

Why is the touch screen not working?

If the sensor is completely unresponsive to touch, then this is probably caused by mechanical damage, for example, when falling. It can also be caused by the penetration of water into the case.

But, it is possible that the problem lies in the OS, especially if the screen does not work only partially. The reason for the glitch of the operating system may be a banal failure / temporary freeze or an incorrect update.

Also, a disconnection or malfunction of the sensor can cause certain program usually downloaded from unknown source. And, it is not necessary that it is "bad" - it may simply 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 on serious turns, then this is probably the work of a virus. Previously, no infection for mobile devices did not exist, but those days are long gone. Often this is the "Autoclicker" virus.

If the screen module has already been changed, it is possible that it was installed incorrectly, something was damaged at the same time, or it itself is of poor quality. There are no options - to carry it back to the unfortunate master.

What else can affect the operation of the screen?

• The screen matrix has failed;
• There was a breakdown of one of the parts of the device, for example, the corresponding microcircuit;
• Internal pollution and, as a result, a short circuit

In the latter cases, without professional help indispensable, but in other cases there is a chance to cope on your own.

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

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

If it does not help, then more radical methods– full reset to factory settings or rollback latest updates. In this case, all data will be cleared, so you should make a backup on your computer before proceeding with this procedure.

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

Sometimes, after a fall, microcracks appear on the protective glass, 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 doing it poorly. There are no options here - the glass is removed, the screen is wiped and a new protective surface is put on.

The case may be in the bumper, which sometimes runs into the screen. Therefore, if everything works fine without it, the protective accessory needs to be changed to a more suitable one.

As already mentioned, a certain program can affect the operation of the axis. For example, the Zillow app leads to similar results, 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, protection will be triggered that disables the control functionality. Here you just need to turn off the device and let it cool down a bit.

How to prevent?

If all else fails, you will have to go to the nearest workshop. And there they will either make, probably, an expensive repair, or they will 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.

For this you need:

1 Protect your smartphone from moisture. Do not leave it near containers with water, use it in a bathhouse or fishing (in any case, be extremely careful at the same time), and also do not talk on it in the snow or rain (moisture will inevitably get into the case or under the screen protection). This is where a headset comes in handy. 2 Needless to say, it is highly undesirable to drop it. For added protection, it's best to carry your favorite toy in a case, even if it doesn't look very pretty. 3 Not all bumpers and protective films perform their functions, and sometimes produce the opposite effect. Dirt gets under a poor-quality film, which scratches the sensor, and an unsuitable bumper itself will wear out the case, and sometimes even interfere with the screen. 4 Do not carry the device without a case in your pocket along with metal objects: keys, small change, key rings, etc.

Conclusion

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

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

Signs of a Bad Sensor in an iPhone

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 all the time or appear for a while, after which the iPhone will start working normally again.

enjoy touch device with a faulty touchscreen is not possible, and you must fix the problem as soon as it occurs. At the same time, 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 the iPhone is not working

If the problem with touch handling is caused by software failure, then the user of the device can eliminate it independently, without resorting to the help of specialists. To do this, you need to perform a “hard reset” of the device by simultaneously holding down the “Home” and “Turn off / on the device” buttons. After 15-20 seconds, the smartphone screen will turn off, 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 the quality of the sensor.

In addition, if the sensor on the iPhone is not working properly, 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 an incorrectly pasted film on the screen. In case of 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 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 in the iPhone are provided, but they only apply to models older than the iPhone 6S and iPhone 6S Plus. It's about about adjusting the sensitivity of the 3D Touch function. To adjust the pressing force to perform various activities when using 3D Touch, you need to do the following:

How to replace touchscreen on iPhone

Replacing a 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 the touchscreen in a smartphone leads to damage to other components of the device, the appearance of cracks / scratches on the case and other problems. That's why it's better to trust Repair iPhone certified service centers.

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

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

replace the entire module;

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

However, there are times when repairs, as such, are not required. Sometimes the sensor stops working as a result of a software glitch, or bad contact plume.

Contact may be lost after a fall, or as a result of low-quality repair at the service center. It is impossible to find out the exact cause of the breakdown without disassembling the phone, therefore, in the absence of the necessary skills, you should not deal with this problem yourself. Unless in the event of a software failure, you can try to fix everything yourself by resetting the settings to the factory settings.

You need to do a reset first. Very often, this allows you to solve the problem with the performance of the sensor and avoid going to the service. To reset the device to factory settings, connect it to a 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. Keep the buttons pressed for 10-20 seconds. After that, the device will reboot. Before resetting, be sure to do backup your phone.

If the reset did not help, then you need to start disassembling. To do this, stock up essential 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 loops are connected. From the display module comes 3 loops. 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 nest, 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 loop connection 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 was not possible to restore working capacity, then it is necessary to change the sensor.

It is best to repair a smartphone in a service center. Having the necessary experience, you can repair the iPhone yourself. The easiest option for this is assembly.

 В this case need to buy new module desired color, disassemble the smartphone and replace the damaged module with a new one. With such repairs, you can not worry about further iPhone health. Work new model should be no worse than a new phone.

 A more complex repair would be required when replacing the sensor alone. In this case, you will have to re-glue the sensor with complete disassembly module. At the same time, it is very easy to damage the working elements - cables, display and protective glass, which is easy to break when sticking the module.

 In some cases, neither the replacement of the entire module, nor its repair, nor the firmware of the smartphone helps, for example, if the motherboard or image controller.

 In this case, you can only repair the phone by soldering the controller or replacing the motherboard. It is better to make such repairs in a service center.

 Before starting work, ask the wizard to diagnose. Only after it will the real cause of problems with the touch screen be understood.

The sensor cable is a flexible prefabricated part.
It first appeared on the iPhone 4 and is colloquially named after its main components - the proximity and light sensors.

Like the top train, this build is constantly evolving.
With each new generation, some small revolution takes place here: one dependent detail "moves", another is added.

An iPhone touch cable needs to be replaced every time one or more of its dependent components fail. It can be:

• sensors (sensors) of proximity and lighting (iPhone 4-6 Plus);
• noise-canceling microphone (iPhone 4-6 Plus);
• front camera (iPhone 5-6 Plus);
• power button flex connectors (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 rest are intact. Reason: the impossibility of soldering the necessary component from the donor part (this is unreliable and uneconomical).

Damage sensor loop: typical cases

Corrosion. Moisture may seep 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 sensor cable) or the docking connector. In 80% of cases, the part cannot be restored and is subject to change.

Physical breakdowns. For example, if the phone hits the floor or any other hard base. At the same time, the risk of bending or damaging the cable increases if the touchscreen is damaged, since it is adjacent to the sensor cable from the inside.

iPhone touch cable replacement: features and duration

The most difficult stage of the procedure is detaching, or rather, lifting the screen module. To do this, stock up on a special suction cup and patience (on the iPhone 5S, if the screen is sloppy and too sharp, the fingerprint scanner cable breaks). Then you need to disconnect the cables and cables passing from the bottom from the motherboard. After installing a new touch cable, the phone is assembled back.

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