Apple Company 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: safety 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 improper 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 simultaneously holding down the “Home” and “Turn off/on device” buttons. 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 calibration capabilities iPhone sensor or iPad users. There are no tools in the device settings that would be responsible for calibration, and only specialists can perform it service center, 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, you must 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.

There are cases 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 an 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 no different high quality, so failure is a completely predictable phenomenon for such elements.
Degrees of touchscreen failure
In practice there are different types iPhone sensor malfunction. The failure may manifest itself as follows:
- 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;
- The touchscreen is completely unresponsive. The digitizer cannot process the touch and transmit it to the motherboard for further display;
- The sensor stops responding after turning on a specific program;
- The phone works fine, but periodically glitches and does not respond to touches;
- 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 most simple methods solutions. 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.
Pay attention! 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. Marking indicated 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.

Understanding that your iPhone has become slower is quite simple. Animations of scrolling through desktops slow down, applications and games take a long time to open, and in general the smartphone slows down. The reasons for this are also simple.
Why iPhone slows down and how to fix it
1. You just installed a new version of iOS
Don’t rush to scold your iPhone for being slow immediately after the update. The system needs some time to index all files, delete the cache, and optimize its performance and the performance of applications. The smartphone will slow down a little, heat up and discharge faster than usual - this is normal.
Actually, there is nothing to fix here. You just need to wait. It's ideal to update in the evening and leave your iPhone on charge overnight to let iOS do its thing.
2. The disk is almost completely full
Filling your built-in storage to capacity can also be a reason why your iPhone is slowing down. No matter how powerful a smartphone is, the system will inevitably work slower if there are a few free megabytes left on the disk.
Fixing this problem couldn't be easier. All you need to do is delete anything unnecessary or dump photos and videos onto your computer or save them to the cloud. Starting from free space It’s convenient to clear it directly on your smartphone from the “iPhone Storage” menu, which is located in the “General” settings section.
3. You updated instead of installing iOS from scratch
Another reason for slowdowns can be accumulated garbage and bugs from previous versions of iOS. This usually happens if you upgrade your device for several years in a row rather than perform a clean install.
To prevent this from happening, it is better to alternate the update with a clean installation and sometimes flash the iPhone via iTunes without restoring from a backup. The very same backup copy It's better to save it just in case. At least in iCloud.
4. Visual effects are enabled on the old device
Modern iOS has many more visual effects and animations than earlier versions. In new devices they do not affect performance in any way, but in older devices they can cause the same slowdown.
The problem is solved by disabling effects, transparency and animations. To do this, open “Settings” → “General” → “Universal Access” and in the “Increase Contrast” item, turn on the “Reduce Transparency” and “Darken Colors” toggle switches.
There, in the “Universal Access” menu, you need to find the “Reduce Motion” item and turn on the toggle switch of the same name.
5. Content update enabled
The usability-enhancing background content refresh feature can also cause slowdowns by loading up the processor with tasks even when the iPhone screen is locked. By disabling it, you can slightly improve performance.
To do this, open “Settings” → “General” → “Content Update” and turn off the corresponding toggle switch. It's simple.
6. You are using the minimum required device for current iOS
Apple supports its devices for as long as possible, releasing software updates even for those that are several years old. To prevent older iPhones from slowing down, developers are optimizing iOS. But sometimes this is not enough.
So if your iPhone is the minimum required to upgrade to new version iOS, the best solution would be to stay on the current one. For example, for iOS 11, such a device is the iPhone 5s.
7. It just seems to you
As paradoxical as it may sound, decreased iPhone performance can often be just a psychological effect. Knowing that a new, faster iPhone has been released, we begin to think that our old and still good smartphone is slower.
This is just self-hypnosis.
How else to speed up iPhone
To get started, you can use an express method to speed up your iPhone, which will not require any complex manipulations and will only take a few seconds. Life hacker talked about him in.
If none of the above works, it makes sense to try resetting your iPhone to factory settings. The easiest way is to proceed in order: first try to reset the network settings, then all the settings, and then completely erase the device.
Before doing this, of course, you need to back up all your data in iTunes or via iCloud.
If this does not help, the last method remains, described in the third section of this article: clean installation of iOS via iTunes and iPhone setup as a new device without restoring from a backup.
The screen does not respond to your touches, the touchscreen becomes dull and freezes: remember if the phone fell into lately? 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
To save money cash, 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.
