The sensor on the iPhone 5s is getting dull, what should I do? The sensor stops working on iPhone, what to do?

It’s a shame when, after replacing the screen on an iPhone 4, 4s, the touchscreen does not work, and using the device becomes almost impossible. Why did this happen specifically to your gadget? It’s wise to ask a specialist in service center(SC), but main reason malfunctions, today, are considered self-replacement display module.

Who is to blame and what to do?

If the touchscreen on the iPhone 4, 4s does not work after you repaired the device at home, following video instructions from the Internet, you only have to blame the “instructor” and yourself. If the touchscreen currently works poorly and intermittently, then after the second attempt to fix it, it will completely stop responding to touches.

If the replacement was carried out at a service center mobile devices, then possible following reasons breakdowns:

• If the phone was hit or dropped, the cable became disconnected or the display module was damaged. Remember, maybe the “apple” recently fell, or the gadget was squeezed into a tightly stuffed bag? Any incorrect mechanical action is a danger to the fragile device.
• Water got on the iPhone and leaked inside. Not even large number moisture can damage parts and oxidize microcircuits.
• Sometimes the problem is the low quality of the spare part that was used during replacement. Are you sure that the iPhone today has an original display module? If the component is a copy, and an “economy version”, then there is nothing surprising in the malfunction.

1. Simultaneously press and hold the home key and the power button of the device for 15 seconds. The device will reboot and display the Apple logo. It is possible that the touchscreen will work better after this.

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 protective film, a bumper that partially covers the screen, various key fobs, covers, 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 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 pressing force 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.

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

If touch iPhone screen 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:

1. There is no need to worry if your smartphone's touch screen is not working properly. This problem, like any other, has a solution.
2. 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 sensor problem was caused by your phone's memory being overloaded as a result of too many 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 the Apple logo appears. Release both buttons. The phone will turn on and should work. No data will be lost.

It's rare for an iPhone's touchscreen to stop working or respond to touch. Obviously, if this does happen to your device, you will touch the screen, but nothing will happen, when you try to perform the “swipe” action, nothing will happen either, or the device will not respond to taps and other actions. If your phone screen stops working, it stops responding to touches and you will be annoyed.

If your iPhone's touch screen has stopped working, read below useful instructions on how to troubleshoot and help solve this problem. There are several reasons why screen problems occur, sometimes they are related to software problems, dirt on the screen or damage to the touch screen or the iPhone itself, but there may be other reasons as well. Read on to find out more.

Troubleshooting frozen touch screeniPhone

There are several steps to troubleshoot touch screen not working on iPhone 8, if your iPhone is not responding to touches and screen then follow the steps to fix the problem. I had a similar problem on my device and I used these steps to fix it, in my situation I just needed to restart my iPhone and free up memory for the touch screen to work.

1. Clean the screen and wash your hands

First, you need to wipe down your iPhone's screen and wash your hands (or clean your other input device). If you have a case or other screen protector, remove it as it may be the reason your screen is not working.

Look at the device under good lighting and tilt it towards different sides to make sure there are no stains, oil, liquid, moisture, crumbs or anything else that could interfere with the screen's operation. In sunny weather, sunscreen that may get on the screen may cause the screen to not work or function properly. Make sure your iPhone screen is clean, clearing it of anything that might be interfering with its operation. Wipe it with a soft cloth to remove everything from the screen, you may need a slightly damp cloth (just a slightly damp cloth is enough) to wipe the screen.

When it comes to your hands, stylus, or other input devices, just make sure they are dry and clean. Wash your hands if you are unsure if they are clean enough. Dry skin or calluses are not typically the reasons why your screen won't respond to your touch, but touching the screen with wet hands can cause it to become unresponsive. Just make sure the screen is clean and your hands are clean and dry.

2. Perform a system-wide reboot

It's easy to do a hard reset, but it all depends on your device model:

• To force restart iPhone 7 and later without pressing the Home button: Press and hold the Volume Down button and the Power button until you see the  Apple logo
• To force restart iPhone 6s and later by pressing the Home button: Hold the Home button and the Power button until you see the  Apple logo on the screen.

When the iPhone turns on, the touchscreen should work again if the problem was due to a simple error or freezing software iOS or apps.

From personal experience I can say that the screen of my iPhone 7 Plus can sometimes stop responding to touches and full reboot always helps.

3. Uninstall or update/reinstall the problematic application

Sometimes the iPhone touch screen does not respond only in specific application. If this happens to you, then most likely the problem is in the application itself, and not in the screen, but when you open the application, the screen stops responding because the application freezes. A frozen app won't respond to any touches, but pressing the Home button will exit the app and return you to the home screen.

If the touch screen is not working on an app, try updating it. Open the application and check the updates available for it, if an update is available, install it.

If the screen still doesn't work after updating the app, the best solution will uninstall the application and reinstall it. Run the application again to make sure everything works. If the problem persists, it is obvious that there is a bug in the application that should be reported to the developers. If the touch screen does not work only when you launch one application, but otherwise works fine, then it is obvious that the problem is in the application, and there is no need to take any action on the screen itself or the iPhone.

4. Free up memoryiOS

When an iPhone runs out of memory, it tends to crash and therefore the touch screen may freeze.

Make sure your device has free memory. You can check this by going to Settings > General > Storage & iCloud > Storage. The main thing is to have at least a few hundred MB; iOS begins to work less efficiently if there is little free memory on it.

Uninstalling apps you don't use is the easiest way to free up memory.

I noticed that indeed in the new iOS versions, if the storage is full, many applications stop responding and the screen does not work. Sometimes even Home button may not respond for a while on an iPhone with full memory until you delete apps or clear the cache. This is easy to check. Just fill up your memory completely and then try to use an app that consumes a lot of memory like Instagram, Twitter, Facebook, Spotify, and so on, when that app fills up the cache, you will notice that the screen will become unresponsive for a while. as iOS tries to cope with the lack of storage memory. In this case, simply free up some space and reboot your device, after which it should start working again.

5. Broken touch screen? Damaged or droppediPhone?

In such a situation, it is obvious from the very beginning that if the touch screen is cracked, there may be problems with its functioning, or the screen may stop working altogether. Also, if your iPhone is damaged, the screen may stop working completely or work inconsistently.

In case the iPhone got wet, the touch screen could break and the entire phone could also break.

If your iPhone has been wet, it is possible that internal components could have become loose, which caused the screen to fail to work.

If your iPhone has visual damage and your iPhone screen is not working, the most likely cause is damage to your phone. The solution in this situation would be to take the phone to an Apple service center or an Apple store.

6. Touch screeniPhone still not working? It's time to take serious action

If your iPhone screen still doesn't work, you can try backup and recovery via iTunes. Just don't forget to do it first backup copy iPhone files in iCloud or in advance in iTunes. If you contact the official technical support, the staff will most likely restore your device. Since it is part of their job to eliminate any malfunctions.

If your iPhone isn't responding because it's stuck on Apple logo, this is a completely different problem that is not related to touch screen, on all devices, you can fix this by restoring the device or using DFU mode recovery.

Touch screeniPhone STILL not working? Seek professional help

If all of the above troubleshooting methods have not solved your problem, then it is time to seek professional help from Apple support, go to an Apple store or visit an official Apple service center. There, your phone will be checked and the reason why the screen is not working will be identified; the device may need to be repaired. There may be a hardware problem or some other problem that you missed.
