iPhone 8 sensor not working

IPhone 8 plus sensor not working | What I’ve done?

Good evening everyone! This is my first post about equipment repair.

In this article, I wanted to talk about repairing the iPhone 8 plus board. the sensor did not work.

He came to me after a field repair.

iphone, sensor, working

-I also noticed that some kind of round scuffs on the back cover!

The explanation for these spots is as follows. Our mother’s exit master confused the cogs and twisted them where the crayons were long. Fortunately, only on the body. Otherwise, a couple of sleeves would have been punctured for sure.

Now about the repair. I always start by clearing the board from previous repairs (flux, rosin, etc.)

Then he began to measure the voltage drop at the J5700 connector relative to the ZXW circuit. All parameters were normal. Except just the bus AP_TO_TOUCH_CLK32K_RESET_CONN_L. She rang through different minivolts every other time. According to the scheme 0.411. and I have 0.740. sometimes 0.510.

I decided to look where he was going. and found the r5768 resistor hanging almost in the air, removed it and installed it again.

After reinstalling the resistor, the voltage drop leveled off and the sensor began to work fine)

All good repairs. I hope the article was interesting!)

it seems strange that only the home master came to change the display, and when did he manage to give a shit with a gumboil under the protective screen? in the same place, unscrew the loops and unfasten 2 plates, and judging by the marks from the large screws, he also shot the cameras.

Hello. If you are sure that the matter is in the periphery (in the front of the camera cable), then the matter is most likely with the IR sensors. Maybe some water got in. But there is no other place.

Yeah, this is such a modern technique, one small zalupon fell off and everything is fucked up)

I don’t think about the resistor, usually traces remain. I think a blow. But the exit master also chopped up with cogs.

What to do with a broken iPhone sensor

There are indeed many possible malfunctions, and the reason for their occurrence is not always obvious. Trying to fix something on the iPhone yourself is a direct way to buy a new smartphone.

The best option is to contact a service center. Before repairing, the device will carry out a full diagnosis of all systems. Directly high-quality iPhone repair is carried out only after the exact determination of the problem.

Repairing an iPhone sensor requires more than just being able to properly disassemble a smartphone and replace various elements. You need to have access to original components and all the necessary tools.

Any iPhone sensor repair can be done at the iLounge Lab. We know how to correctly diagnose a malfunction, and most importantly, to correct it correctly. Your smartphone will be in the hands of professionals!

How a damaged iPhone sensor behaves

Let’s start with possible problems with the iPhone sensor:

  • No response in certain areas of the screen.
  • The response to the owner’s touch is delayed.
  • Ignoring touches completely.
  • Variable triggering.
  • The sensor works independently, without user intervention.

There are many reasons for all this disgrace. The most common problem is shock when the smartphone is dropped. This leads to damage to the screen and the sensor itself. Also, the motherboard of the iPhone may break and quite often this is reflected in the operation of the sensor.

A factory defect is less common. If this happens during the warranty period, it’s a great excuse to update your iPhone for free. At the end of the warranty period, the problem will have to be solved independently.

Today, touch has become a common standard in the mobile industry. For its time, the complete rejection of pushbutton input was a real technical revolution. Unfortunately, we have become a kind of “hostage” of touch input.

If the sensor on your iPhone breaks down, it is simply impossible to use your smartphone. There is simply no way to communicate with him. The most you can do is just take calls through a wired headset and use the Siri voice assistant to take some action.

ILounge Lab service technicians often encounter such customer complaints. We want to tell everyone where such problems can come from and how to deal with them.

Repair cost if iPhone sensor doesn’t work

Our wizard will carry out a free diagnosis of your iPhone 12/12 mini / 12 Pro / 12 Pro Max / 11/11 Pro / 11 Pro Max / SE 2 (2020) / XR / XS / XS Max / X / 8/8 Plus / 7 / 7 Plus / 6s / 6s Plus / 6/6 Plus / SE / 5S / 5c / 5/4 / 4S.

Manifestation of problems

First of all, damage to the sensor manifests itself in how the phone reacts to touch. The touchscreen may respond to them with a delay or not respond at all to pressing. It is possible that there will be “phantom” touches when you do not interact with the phone, and the phone independently starts turning on applications, opening SMS messages, dialing contacts or random numbers. Also, if damaged, the sensor tends not to work in any part of the screen. top, bottom, right, left.

What to do if iPhone sensor is not working?

Try restarting your phone first. it might help if sensor issues don’t appear on a consistent basis. Restart methods are different on different iPhone models. On the line of iPhones from iPhone 4 to iPhone 6S Plus, reboot is carried out by simultaneously pressing the power and home buttons

proximity sensor not working on iphone

On models from iPhone 7 to iPhone 11 Pro Max, reboot is carried out by pressing “Power” and the volume control button, namely, its decrease.

Also, if your sensor has begun to work worse, the reason may be the accessories that are worn on the phone: a case, protective glass, and so on. The protective glass may be incorrectly installed, as a result of which it is not firmly in relation to the screen, and therefore your touches are poorly tracked by the touchscreen. And accessories like a phone case can also be a cause of breakage, because they “crush” the screen, as a result of which its performance, namely the sensor, deteriorates. To check if this is the problem, you need to remove the covers and protective glasses and start the phone without them.

If this procedure did not help you, as well as restarting the phone, then you should contact the service center and entrust the iPhone to professionals in their field. In such centers, specialized wizards can offer you several options for troubleshooting problems. First of all, the phone will be diagnosed for faults. If such a malfunction with the screen is found, then a professional will replace the screen.

In order to repair the new lines of Apple phones, professionals can replace the entire display module. This happens due to the fact that the replacement of any one element of the module may entail other malfunctions, therefore the wizard does not recommend, for example, a separate replacement of the screen or display loop.

IPhone sensor malfunctions

Despite the fact that Apple products are of very high quality, iPhone owners often face such a problem as a non-working sensor, or, as it is also called, a touchscreen. The sensor may not work partially, or completely fail.

A variety of factors can cause the screen to not work. These reasons, first of all, include all kinds of mechanical defects as a result of physical impact on the iPhone. A vivid example is shown above, due to a strong impact when the iPhone 5 is dropped, the touchscreen will not work in 98% of cases.

Manifestations of an incorrectly working sensor on the iPhone

  • IPhone touchscreen ignores and does not respond to touches in certain areas / areas.
  • The touchscreen responds with a delay to pressing.
  • The iPhone’s sensor ignores all touches, and does not work at all.
  • The phone screen (including the sensor) lives its own life: text is randomly typed, applications close and open on their own (without user intervention), pages of documents are turned over incorrectly.

What to do if the sensor stops working? Try the following:

  • In case of periodic display of malfunctioning of the touchscreen on the iPhone (the sensor on the phone works, but its work occurs with a large number of failures and errors), you should perform a full reboot of our device. You can do it this way:
  • Simultaneously hold down the power button and the “Home” button;
  • We keep the buttons in this state for at least 15-20 seconds;
  • After that, the iPhone will restart;
  • If, as a result, the standard Apple logo appears on the screen. you did everything right.
  • If a protective film is glued to the screen of your iPhone, or a new cool bumper partially captures the screen. remove everything and check the sensor performance again. Perhaps the screen will work again, and similar accessories contributed to the malfunction.

It may happen that you do all of the above, but you still don’t get the result, the faulty touchscreen will not come to life? Then, most likely, you should think about a visit to an Apple service center. The service center staff will help assess the condition of the phone, find out the cause of the problem, and, in which case, replace the screen.

By the way, the repair time, namely replacing the screen on the iPhone, takes about an hour. Are you surprised? And this despite the fact that such a fast execution does not affect the quality in any way. As a rule, this situation has developed due to the fact that sensor replacement is the most common repair procedure in Apple service centers.

There are times when the screen refuses to work due to deformation or damage to the board. but such breakdowns are quite rare. With such a malfunction, you will have to leave your favorite gadget at the service center for a longer period of time. After all, diagnostics and solving serious problems take longer than a standard sensor replacement.

In order not to ask stupid questions at the service center, remember: all generations of iPhones, from the fourth to the sixth (at the time of this writing, the iPhone 6 Plus is the latest model), are equipped with a touch glass, which is located in the display module and is an integral part of it. The display module itself consists of 3 such elements. the top glass (protective), the sensor (touchscreen) and the display itself.

That is why, if the touchscreen on the iPhone fails, the entire module will have to be changed. And if you break the display, the whole module changes. And if only the upper protective glass is broken. You already guessed what will need to be changed?

If you have an iPhone 6 or 7, read about sensor repair and calibration in a new article here. We have collected the latest information for you about sensor faults.

Trust iPhone repair only to professionals

Yes Yes Yes!. I also saw hundreds of videos on YouTube and searched Google for step-by-step master classes for repairing or replacing a sensor on an iPhone. I will say even more, I myself broke the screen of my iPhone more than once and, following various replacement videos, tried to fix everything. In 50% of cases, my attempts ended in success), this despite the fact that I am a radio amateur and know electronics firsthand.

By the way, the last case ended with the fact that, changing the display, I touched an important detail and was left without sound. This part cannot be restored, so now I have to use a “silent” iPhone. You can see a similar video of the repair below.

That is why I recommend to entrust iPhone repair only to people who professionally service Apple equipment, in other words, those who work in official service centers.

By contacting an under-serviced center or buying a cheap fake high-quality part for self-installation, you endanger the device as a whole.

  • The part may turn out to be so low-quality that after a short period of time, you will be forced to turn to a professional to eliminate even greater damage.
  • As for the unscrupulous service centers, everything is not smooth there either. Firstly, you are not given any official guarantees, and secondly, the same cheap parts can be presented as high-quality.

By contacting the official service center of the manufacturing company, you get a guarantee that the work will be done with high quality, your money will not be wasted, and the device will serve you properly for a long time. over, smartphones like those from Apple have their own subtleties, specifics, individual design features and internal structure. a simple mistake when repairing this technique can lead to unpleasant consequences.!

Do not forget to read the Комментарии и мнения владельцев, there is also a lot of useful information. If there is no answer to your question, and there is an answer to later Комментарии и мнения владельцев, then the answer to your question is contained in the article, respect someone else’s time.


Drops falling on the screen of a smartphone can cause conflicts in the operation of the touchscreen. If the iPhone screen is wet, be sure to wipe it dry and then check the sensor. In the event that the phone has fallen into liquid, it must be dried and then checked for operation. How to properly dry a smartphone that has fallen into water, read the article below.

Why did the sensor stop working on the iPhone

Damage to the touchscreen

In this case, the smartphone screen may work partially or completely stop responding. Most often, this type of problem occurs as a result of the fall of the phone. and the glass may not break. The fact is that the iPhone screen is a kind of “layer cake” consisting of an outer glass, a touchscreen and a display. Due to the impact of the phone on a hard surface, damage could occur to the middle part of the screen. the touchscreen, which is responsible for touching. As a rule, you can verify this by looking at the iPhone screen at an angle. if you see stripes or cracks under the outer glass, but the display itself works, with a high degree of probability we can say that the sensor is damaged. In this case, you should contact the service center, where a specialist will promptly replace the damaged element.

The smartphone is frozen

If the phone has not been physically affected, it should be assumed that it simply froze, which means that the most affordable way to fix the problem is to force a restart. How to implement a forced launch, we previously talked about on our website.

Reasons for the inoperability of the touchscreen on the iPhone

IPhone touchscreens can stop functioning for a variety of reasons, but they can be divided into two main groups: software issues and hardware issues. The former are caused by a malfunction of the operating system, the latter, as a rule, arise due to physical impact on the smartphone, for example, as a result of a fall. Below we will consider the main reasons that can affect the inoperability of the touchscreen, as well as ways to bring it back to life.

Protective film or glass

If your iPhone has film or glass, try removing it. The fact is that low-quality protective equipment can interfere with the correct operation of the touchscreen, and therefore the sensor does not work correctly or does not react at all to touches.

Operating system malfunction

Again, a similar reason should only be assumed if the phone has not been dropped or otherwise exposed. If restarting your smartphone does not work, and the touch glass is still not responding to touch, you might think that iOS has a serious malfunction, as a result of which the iPhone cannot continue its correct operation.

  • In this case, you will need to flash the device using iTunes. To get started, connect the gadget to your computer using the original USB cable and launch iTunes.
  • Enter the phone into DFU special emergency mode.

  • Normally, after entering the iPhone into DFU, iTunes should detect the connected phone and offer the only solution to the problem. is to perform a restore. When you agree to this procedure, the computer will start downloading the latest firmware available for your smartphone model, after which it will remove the old operating system, and then perform a clean installation of the new.
  • application

    Often, the iPhone sensor does not work when a certain application is launched. this problem arises after the next version of iOS is released, when the program developer did not have time to adapt his product for the new operating system.

    In this case, you have two solutions: either delete the problematic application, or wait for an update that will fix all the problems. And in order for the developer to hurry up with the release of the update, be sure to inform him about the presence of a problem in the work on the application page.

      To do this, launch the App Store. Go to the “Search” tab and then find and open the page of the problematic application.

    If the tips above did not help and the iPhone sensor still does not work properly, contact a professional. Experienced masters of the X-Repair service center will carry out free diagnostics of the gadget to determine the reasons for the breakdown, for which the sensor does not work in the iPhone. If the problems with the touchscreen of the smartphone are not in the display module, the iPhone motherboard needs to be repaired, which will be done at the “X-Repair” SC at the best price.

    Why iPhone sensor doesn’t work?

    There are many reasons why the sensor does not work on the iPhone. The touchscreen iPhone may stop working due to a factory defect in the touchscreen, a fall from a height, or a shock. However, in addition to damage to the display module, a common reason why the iРhone sensor stopped working is a malfunction of the motherboard. Damage to the device board can be either a shock or a fall on a hard surface, or moisture ingress into the smartphone case, which will lead to corrosion of the conductive elements of microcircuits.

    But most often, the malfunctioning of the touchscreen, regardless of the iPhone model, is caused by mechanical damage due to the failure of the owner of the smartphone to follow the basic rules of operation and banal carelessness. This leads to the fact that as a result of falls, the microcircuits that are responsible for the operation of the iPhone sensor are damaged and the touchscreen begins to work intermittently. In order to find out the exact reason why the sensor on the iPhone does not work, you need a specialist consultation and smartphone diagnostics. If the problem with the device’s sensor is not in the display module, then the iPhone motherboard needs to be repaired. The specialists of the X-Repair service center will promptly repair your iPhone at the best price.

    What to do if the iPhone sensor does not work

    Apple products are renowned for their quality throughout the world. However, despite the excellent build and high-quality components, all iPhones have their weak points. Gadget owners often complain that the touchscreen does not work in their iPhone. In this article, you will learn why this happens and what to do if the sensor does not work on the iPhone.

    How iPhone sensor problems manifest:

    • There is absolutely no reaction of the iPhone touchscreen to touches;
    • There is no sensor response in some areas of the display;
    • The response of the sensor to the command is delayed;
    • The touchscreen of the smartphone does not respond to all user commands;
    • The iPhone’s sensor triggers randomly. the device itself opens and closes applications or documents, types text without user intervention, etc.

    What to do if the sensor is not working on iPhone

    If the iPhone owner notices that the image on the phone’s display suddenly starts to display with interference, the sensor stops responding to touch, and tactile commands are sent and executed spontaneously, he usually thinks that the problem will be solved by replacing the display module. However, even after replacing the display, all these problems remain. How to solve them?

    On iPhone 6 Plus, the sensor often does not work correctly

    Why iPhone screen glitches

    Sensor glitches, interference on the iPhone screen and other similar symptoms are typical for the iPhone touchscreen controller not working correctly. These symptoms include:

    • The sensor works every other time
    • Stripes appear on the screen
    • The phone lives “its own life”, the commands are executed independently

    This issue is common on iPhone 5, iPhone 5s, iPhone 6, and iPhone 6 Plus. Before the iPhone 6s, these controllers were located on the motherboard: only then Apple began to place them on the display part.

    Such stripes on the iPhone screen may indicate that the touchscreen controller is not working properly.

    Why is it failing? Most often this happens due to the penetration of moisture into the case or mechanical impact on the phone. a small fall from the sofa is enough. The motherboard has a high density of BGA chips, so any physical contact can lead to disruption of their work. Falling or getting moisture into the phone can cause a violation of soldering, breakage of contact tracks and even damage to the microcircuit itself.

    However, it happens that the problem arises after an unscrupulous repair. It is very easy to damage (overheat) the components of the iPhone board if you work carelessly. In any case, a qualified diagnosis is required to identify the exact cause.

    Is there a problem in the controller or display? Only a specialist will understand

    How to fix iPhone sensor problem

    You can get rid of these inconveniences by replacing the iPhone touchscreen controller. At home, this will definitely not work. replacing the microcircuit located on the motherboard is a complex procedure that requires experience and skills. Therefore, we turned to the Apple Pro service center, which showed us the iPhone 6 Plus repair.

    Touchscreen controller repair process

    Since the touch controller in the iPhone 6 Plus is located on the inside of the motherboard, you need to almost completely disassemble the phone to access it. The battery and all cables are disconnected.

    The display module is removed, all loops are disconnected

    For safety (and ease of use), the motherboard is removed from the iPhone and placed in a special holding device.

    Motherboard removed from iPhone

    The engineer uses a hot air station and heating to remove the old controller. Since all the components on the motherboard are tightly packed (for example, there is a processor on the back side), the temperature regimes are observed very strictly. Overheating can cause problems with other microcircuits, which will require additional repair.

    System board without touchscreen controller

    The specialist cleans the contact pads and prepares the board for the installation of a new microcircuit.

    Often the problem lies in the breakage of the contact tracks on the motherboard. Therefore, after dismantling the old touch controller microcircuit, the engineer begins to restore the breaks on the board. For recovery, he uses a circuit on a computer and special software.

    Microcircuit in place, tests can be carried out

    After repair, a seal is installed on the components. it is damaged by physical influences from the outside
