iPhone 5s sensor freezes. How to fix iPhone sensor problems yourself

The reason that the iPhone screen does not respond after touching your finger may be moisture, dust getting inside or mechanical damage. The main indicator of malfunction touch display is a partial reaction of the touchscreen to pressing or randomly typing text. In some cases, the iPhone screen does not respond to touches because the smartphone is frozen. By following a series of procedures, you can determine why the display is not working properly.

Common causes of breakdowns

Most often, the iPhone screen does not respond to the touch of a finger after a fall, liquid ingress through cracks, or due to other mechanical damage. Quite rare causes of problems are the following defects:

touch screen wear
high RAM usage (the iPhone screen has stopped responding and the buttons are not responding because the phone is frozen)
malfunction iPhone systems(the smartphone does not respond to button presses)
overheating of iPhones (in such cases, part of the screen does not respond to touches)

It is easy to determine the presence of problems in the operation of the sensor; the following failures are observed:

The iPhone screen partially or completely does not respond to touches
In certain parts of the display, the iPhone screen freezes when touched with a finger
The screen responds to touches with a delay
Pages don't turn correctly
the sensor has stopped responding to touch and is typing text spontaneously

To avoid problems with iPhone displays due to mechanical damage, the manufacturer recommends gluing glass or film to the surface of the screen.

What to do if the sensor stops working

If your iPhone screen stops responding, you don't always need to replace the display. In some cases, you can independently determine the cause of the problem and fix it. First, eliminate the possibility of damage to the case or screen surface.

If internal components break, only a qualified specialist can repair the iPhone.

If your iPhone screen freezes, follow these steps:

use the power button to reboot the device (you need to hold the button for a few seconds)
remove unlicensed software from iPhone
reflash the device

If after performing these steps the iPhone screen freezes and there is no response to button presses, you need to completely reboot the device. To do this, you need to simultaneously hold down the “Home” and “Power” buttons for 20 seconds. The smartphone will then erase the RAM and restart the phone.

If after this part of the screen or the entire display still does not respond well to finger presses, the sensor needs to be replaced.

Installing a new display module

The iPhone screen cannot be replaced separately from the sensor or touchscreen. If the display does not respond well to touch due to damage, then a new module must be installed. Qualified specialists can identify the exact cause of problems using computer and mechanical diagnostics. The technicians will determine exactly why the smartphone is frozen, the device is not rebooting, or part of the screen is not working.

What can you do if the sensor on your iPhone 5s doesn’t work well after replacing the screen?

If touch screen The iPhone works intermittently or does not respond to touch at all - this is one of the most unpleasant and complex problems, which only smartphone owners can encounter. This is due to the fact that working with iPhone and other Apple devices It is completely touch-based and is the primary way of interaction between the user and any type of apps installed on the smartphone.

Apple has taken note of the increasing incidence of sensor malfunctions in its products and this happens much less frequently in new models. However, the problem has not disappeared completely. Some users, quite a short time after purchase, notice that the sensor responds with a long delay or does not respond to touch at all. In most cases, these problems arise from the LCD screen, but in some cases, simply rebooting the device or cleaning the connectors will help resolve the situation.

Possible causes of sensor malfunctions

If, after replacing the screen, the sensor on your iPhone 5s does not work well, it is worth figuring out what caused this problem.

Causes of sensor failure:

Too many programs and applications are running at the same time, which causes problems with RAM devices, which in turn slows down the sensor;
Liquid getting on the phone;
Accumulation of debris and dirt on the screen;
Dry soldering of touch screen connectors;
Malfunction of the primary or secondary touch screen control system;
The touch screen has received physical damage.

Ways to solve the problem:

There is no need to worry if your smartphone's touch screen is not working properly. This problem, like any other, has a solution.
First of all, you can try to remove the protective cover of your device's screen, as this could be the obstacle.

If this does not help, you can try the following logical steps:

Reboot your iPhone. If the problem with the sensor was caused by an overload of the phone's memory as a result of too much large quantity running applications, then the simplest solution to the problem is to reboot the device. To restart your iPhone 5s, simply press and hold the sleep/power button, which is located at the top of your smartphone.
Reset. If a simple reboot doesn't help, you'll need to reset your iPhone. To do this, press and hold the Sleep/Power button and the Home button simultaneously until Apple logo. Release both buttons. The phone will turn on and should work. No data will be lost.

The delicate touchscreen mechanism sometimes gives unexpected failures. This can happen either spontaneously or after manipulation. Let's look in detail at why the sensor on the iPhone 5, 5s lags, and what to do in such cases.

Reasons

Most users encounter problems managing their device after replacing the screen in an unqualified center. Poor quality work and non-original parts lead to the fact that the phone perceives presses distorted, has an insensitive zone, acts spontaneously or does not respond to touches at all.

The sensor on the iPhone 5, 5s can start to fail due to a number of other factors:

after the fall, microcracks have formed, dust and moisture enter;
incorrectly installed safety glass or film;
contact with liquid that reduces the sensitivity of the sensor;
natural wear and tear, abrasions on the display that distort the operation of the touchscreen in one area;
software update failure;
the program is incompatible with iOS or the current version;
malfunction of internal structures caused by power surges.

Pay attention! The device does not have a cooling system. CPU overheating is one of the reasonswhy does the touchscreen work poorly?. Avoid prolonged exposure sun rays on the gadget and, if you detect unnatural heating during charging or use, immediately contact a specialist.

DIY repair

When the screen on an iPhone 5 or 5s is glitchy, the owner can take a number of actions to improve performance:

Reboot your system. To do this, hold down the "Home" or power button for 10-15 seconds.
Remove the protective covering and thoroughly clean the touch screen surface.
Silicone cases delight with their bright design, but not always with quality. You should remove the purchased protection and check its functionality.
If screen problems are caused by software problems, return the device to factory settings or perform a system rollback to remove the result of an incorrect update. Please note that all data from the memory will be deleted: before you begin, you should transfer the information to your PC.

If none of the measures help, a professional will solve the problem.

Where to go for help

Our service center is open to all owners of Apple products. A specialist will replace the screen and microcircuits if:

the device is filled with water;
undergone preliminary repairs;
dull when pressed after a fall;
The lower part of the display does not work after overheating.

Important! Professional tools are used to replace the screen matrix and display controller. Repairing requires skill and dexterity. It is impossible to do it yourself at home.

Ordering professional diagnostics and repair of iPhone 5 and iPhone 5s in St. Petersburg is cheaper than purchasing a new device or changing the motherboard.

Symptoms of a problem

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.

Reasons

Now it would be nice to find out what reasons lead to 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.
Because of 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 problem is not caused by accessories.

Troubleshooting a software glitch

One more common cause problems with the sensor may occur 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

In the event that the restart procedure described in the previous section helps, but after certain time Again, the sensor does not work on the iPhone, 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 normal operation operating system and leads to all sorts of problems.

The best thing, of course, is to delete everything 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 possibility of full calibration 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 tab " Universal Access».
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 required 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 does not take 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.

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 protective film. Without additional protection, when dropped from a great height, the touchscreen of a fifth-generation iPhone, for example, stops working in 98 percent of cases. However, it is not excluded that the sensor does not work on the iPhone, software reason. That is, a failure within the operating system.

Manifestations

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

A manifestation of the fact that the sensor on the iPhone does not work can be a complete disregard for all touches and simply refuses to process them. By the way, when problems arise with the touchscreen, this becomes a real source of problems for beginners just getting acquainted with Apple technology. So they start looking if the sensor doesn’t work. Another sign that clearly indicates the need for sensor repair is the random life of the device. That is, it can type a sequence of characters on its own, 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 prevent it from working properly. To check whether this is the reason, simply remove it from the device and use the touchscreen again a little. If normal operation will be restored, the problem is really in the bumper, and something will have to be done about it. If nothing has changed at all, then you need to move on and look for the reason for the incorrect functioning.

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

In this case, you need to schedule and carry out a visit to the service center as quickly as possible, where specialists will inspect the screen and, if possible, return it to normal 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 a 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.
