Iphone 5s sensor glitches after replacing the display. IPhone touchscreen not working or not working well - here's the fix

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

In iPhone and iPad, the 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.

You cannot use a touch device with a faulty touchscreen, and you must fix the problem as soon as 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 a problem with touch processing is caused by a software glitch, then the device user can fix it independently, without 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 the Apple icon will light up - 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 a way for users to calibrate the iPhone or iPad sensor. 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, 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 to independently replace the touchscreen in a smartphone lead to damage to other components of the device, cracks/scratches on the body, and other problems. That is why it is better to trust iPhone repairs to 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.

Some lucky iPhone owners sometimes have to deal with a rather unpleasant problem - the sensor on the iPhone 5S is glitchy. 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 do it on your own, but in some particularly difficult cases you cannot do 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 with 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 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, a certain program, usually downloaded from an unknown source, can cause a sensor to be disabled or malfunction. And it doesn’t have to be “bad” - it just may be incompatible with the current version of the axis or, in general, be illegal among 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 well?

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 the Home and Power buttons for 10-15 seconds. 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 rolling back the latest updates. In this case, all data will be cleared, so you should make a backup on your computer before starting this procedure.

Also, it is 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, 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 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:

1 Protect your smartphone from moisture. Do not leave it near containers of water, use it in a bathhouse or while fishing (in any case, be extremely careful), and also do not talk through 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 extra protection, it's better to carry your favorite toy in a case, even if it doesn't look very nice. 3 Not all bumpers and protective films perform their functions, and sometimes have the opposite effect. A low-quality film gets underneath dirt, which scratches the sensor, and an unsuitable bumper itself will wear out the body, and sometimes even interfere with the operation of the screen. 4 You cannot carry the device without a case in your pocket along with metal objects: keys, change, key fobs, etc.

Conclusion

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

A touchscreen is a touch screen that you can touch to control your iPhone. Apple products boast a reliable and sensitive sensor, but even this can fail over time or due to careless handling.

Reasons for touchscreen failure

Problems with the touchscreen, regardless of the model, can be caused by:

a blow or a fall;
corrosion or short circuit due to moisture;
controller malfunction;
failure of the touchscreen chip;
broken motherboard contacts;
previous repairs using non-original parts.

What indicates a faulty touchscreen?

The following signs indicate the need to repair the sensor:

slow touch response;
the display glitches when pressed;
the sensor completely ignores touches;
the display is pressed spontaneously, without touching;
pages are difficult to switch;
There are areas on the screen where the sensor does not work.

How to solve problems with the sensor yourself?

Before resorting to the help of specialists, you can try to cope on your own (especially if the touchscreen is glitching for the first time, and no other faults have been noticed with the device). To do this, follow these steps:

Press and hold the power and home button.
Wait 20 seconds for your phone to reboot.
Test the sensor again.

Also remember if you purchased new accessories for your phone: protective glass, case, bumper or magnetic keychain. Check the operation of the touchscreen by removing them.

Features of touchscreen repair on iPhone

If all simple causes of the malfunction are excluded, then the problem of a non-functioning sensor should be addressed to a specialized service center. The technician will conduct a professional diagnosis, after which a decision will be made to repair or replace the phone’s components.

If the fault lies in one of the parts of the display module or cable, then the entire part is replaced completely (separate replacement of the sensor or contacts is not carried out due to the unreliability of such a procedure).

Even if the iPhone's touchscreen functions properly most of the time, periodic malfunctions clearly indicate the need for repair. Don’t delay contacting our Total Apple service center so that your favorite iPhone doesn’t let you down at the most inopportune moment.

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 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. 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. Interruptions in the operation of the sensor become longer and longer, and the crack expands 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 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 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 of errors and inaccuracies. In this case, we can solve this problem quite simply. 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 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 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. Don’t be tormented by the question “The sensor doesn’t work on your iPhone, what should I do?” when even a full reboot doesn’t help. 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 another device from 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

Deformation of the screen or even damage to the motherboard that occurs 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 a single complex required for further correct operation.
