Screen glitches while charging. The touchscreen (sensor) on an Android phone or tablet does not work well. The touchscreen (sensor) works on its own, it works some time after pressing, it is dull, lags, and does not work correctly. What to do and

Greetings to one and all! I didn’t want to write the title of the article exactly like that, but it’s very difficult to find another word other than “buggy.” It describes everything very succinctly (the mighty Russian language is rich and beautiful!) possible problems with a screen that lives on its own - keyboard buttons are pressed, desktops are scrolled, applications are launched, and all this without your knowledge. And the display itself does not respond to pressing!

It would seem that the situation is fantastic and somewhere even mystical, but... in fact, there is nothing strange in this - everything has a logical explanation. Which? Now we’ll find out everything! But first, let's determine after what actions the screen of your iPhone or iPad can begin to live its own life, create chaos, and run amok. full program and scare its owner.

There are not so many of these actions:

1. Firmware update.
2. Physical damage (fall, shock, moisture).
3. Replacement or repair of the display (nuances may apply).

That's all. Although no, there is another option - none of the above happened, and the screen suddenly began to “glitch”.

Let's start with general preparation of the device, which will help eliminate some standard issues that cause the touchscreen to behave in such an incomprehensible way:

• If there is film or glass stuck to the device, remove it.
• Wipe the screen thoroughly with a soft cloth. Do not use special cleaning fluids; sometimes they can simply ruin the oleophobic coating.
• To rule out a software problem and errors in iOS, do this.

Yes, everything listed above is quite banal, but it can help. However, these are not all the actions that can be performed in order to improve the operation of the display.

And the first thing you should pay attention to is non-original power supplies and Lighting cables. Although most likely we will talk about the wires (the adapter itself, as a rule, does not greatly affect the operation of the device). Yes, they can spoil your nerves.

Once I myself encountered this and saw how a person’s phone was charging and at the same time periodically lit up, the screen unlocked, pressed on its own, and characters were typed on the keyboard. To be honest, I was very surprised how the iPhone hasn’t called somewhere on its own yet!?

After a short conversation, it turned out that although this bothers the person, he simply does not want to buy an original wire (I rarely use it, and it will do!). The fact that spontaneous pressing of the display is not the worst thing that can happen, and the battery will definitely have to be changed soon, did not interest him.

Conclusion one: if the iPhone display lives its own life and does not respond to touches only while charging, the charger is most likely to blame. Replace and use only certified accessories.

If everything is ok with the charger, then you should move on to the next reason - these are low-quality display modules. There are simply a huge number of them, but there is an explanation for this:

1. Many models are simply wildly popular, for example the iPhone 5S.
2. China will help everyone.

Here you have a large number of screens of varying degrees of quality. Moreover, they can be installed both during repair and on “new” (in fact, restored from an unknown location) iPhone. And if you are unlucky and the screen is set completely to the left, then accidental clicks and other pleasures of life are guaranteed.

By the way, a characteristic feature of this defect is that after blocking/unlocking the device everything returns to normal, but for a while, and then it starts to “glitch” again. This can appear either immediately after repair/replacement or after updating iOS. What to do in this case? Option two:

1. Set to normal display.
2. Try gluing film or glass.

The most interesting thing is that some workshops, knowing the quality of the display they are installing, when replacing a module, stick a sticker on the screen as a “gift”. Often this is done just so that the iPhone or iPad display behaves correctly and does not live its own life. Brilliant move! The difference between a good and a bad screen is big, but the price of the film is small. And everyone is happy: the client thinks that the service is good - he even glued the film, and the workshop itself won money.

Conclusion two: if the iPhone display is “buggy”, most likely it is simply not of very good quality. Replacement required. There is also a more budget-friendly solution that helps many people - sticker of film (glass). With the iPad the situation is completely similar, only it’s harder to glue :)

There is another reason why the touchscreen may behave strangely. But here it would be more correct to say that it will not process clicks at all, and not “just” trigger in the wrong place.

Perhaps we are talking about the display sensor controller and this is very sad. It can be damaged if it falls, gets bumped, gets moisture inside the gadget, or is missing. Only a few service centers have the skill to resolder it (the procedure is done so as not to change the entire motherboard). Well, it also costs money accordingly - of course, cheaper than completely replacing the board, but still...

Conclusion three: the most serious malfunction in which the iPhone display is pressed by itself is a breakdown of the screen sensor controller. Compared to previous problems, it is rare and much more difficult to correct.

This is the unpleasant conclusion at the end of the article...

However, I really hope that all the “glitches” of your iPhone screen will be cured by simply replacing the charger, wire, or, as a last resort, a sticker of film or glass. And it won’t come down to complex repairs at the service center. Let it be so!

P.S. And to increase the chances of a successful outcome - put “like” and click on the buttons social networks, +50% luck guaranteed :)

P.S.S. And of course, if you have questions or practical tips on how to overcome a “glitchy” display, be sure to write in the comments!

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.

Causes

Most users encounter problems managing their device after replacing the screen in an unqualified center. Poor workmanship 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;
• the protective glass or film is installed incorrectly;
• 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.

Note! The device does not have a cooling system. CPU overheating is one of the reasonswhy does the touchscreen work poorly?. Avoid prolonged exposure to sunlight on the gadget and, if you notice any 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:

1. Reboot your system. To do this, hold down the "Home" or power button for 10-15 seconds.
2. Remove the protective covering and thoroughly clean the touch screen surface.
3. Silicone cases delight with their bright design, but not always with quality. You should remove the purchased protection and check its functionality.
4. 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 starting, 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;
• does not work Bottom part display 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.

Good afternoon. I'm having problems with my Galaxy S II phone when it's charging. The screen completely loses sensitivity. It is impossible to use the phone. What should I do? I read on the website, in the popular questions section, a similar question and the answer to it: Monoblock: There is a problem with the GT-S5660 screen reacting to touches when it is charging from the mains. Switching between desktops practically does not occur. Shortcuts on the screen do not work. Working with the phone is very problematic. When you disconnect the charger, everything works fine. While the phone is charging, the touch screen may not respond to touches. This occurs due to an unstable power supply. In this case, disconnect the charger from the phone. This answer is completely unclear to me. What does the expression This occurs due to an unstable power supply actually mean? What exactly is the problem? In the charger? In the outlet? Do you advise that in this case, disconnect the charger from the phone. How to charge it? And what exactly should I do to solve this problem?

Charge it with the original charger or then don’t use the phone while charging. This happens because the output voltage is too high and therefore the screen completely loses sensitivity, i.e. .e. he thinks that the entire screen area is pressed. And in 99% of cases this happens when using a non-original tooth.

  I have the same problem, and no one can give a clear answer. I bought a branded, original charger. I tried holding the phone in one hand, but of course the situation did not change. This does not happen when charging from USB. Tell me, what could be the reason?

  answer/answered:

  Helpful answer? (5) / (1)

  Loss of screen sensitivity, shortcuts on the desktop, etc. When charging the device from a network charger, this is due to the fact that this charger is not original. Using the example of our Samsung galaxy fit (s5670), the original charger has the following characteristics of a mini USB connector: Uout = 5V, Iout = 0.7A. The connector has 4 contacts. Voltage is applied to the two outer ones (1 and 4), the inner two (2 and 3) must be connected to each other (shorted). Pins 2 and 3 are used for data transfer. That's not really the problem. On some non-original or “burnt” chargers, contacts 2 and 3 are not connected to each other. As a result, the phone begins to function incorrectly (glitches). Even if the phone was purchased at a mobile phone store and it says Samsung on it, this does not mean that it is original! The other day I paid 550 rubles for this. I took it apart - a bare fake, poorly assembled. Beware of fakes! Check on site.

  Alexander, what you wrote is complete nonsense. I disassembled the original charger, and it’s not the original - everywhere 2 and 3 contacts are not shorted. There are no wires there at all, but on the connector itself, I tried connecting them to each other and opening them - the result was zero. Just as the screen didn't work, it still doesn't work. But on the original everything is ok. The only thing is that I measured the voltage in the original - 5.05 V, and in the fake - 5.4 V, and in the fake the current strength drops significantly under load. Conclusion - most likely the touchscreen does not work due to incorrect current and voltage.

The same thing is very noticeable when debugging the screen. You place your finger, and the screen thinks that it is being pressed in neighboring areas. A defect appeared on firmware 4.0.4, I did not roll back it, it appears on all devices. Both original and non-original. Maybe the controller was burned by non-original ones...

The problem is identical, the sensor does not respond adequately to touch while charging. But it's not the voltage, it's the network.
When my device is connected to the laptop, it is charging and everything seems to be fine, until I connect the power directly to the laptop, while the smartphone, being charged from USB, starts to turn off. The voltage seems to be the same, I think that in some charging there is “protection” from potential differences, like a filter.

99% of the reason for glitches when charging is not stable voltage at the charger output. I bought a charger on the market (original according to the seller) and also a phone. buggy. I connected it via a data cable and a power supply from the media player (Chinese, but good quality), everything is fine. When charging from a USB computer, everything is also fine. Disassembled the so-called original, and oooh.....WONDERFUL - typical Chinese garbage. It couldn't be worse.

I also had a problem with charging! I have two of them, one at work, the other at home. At work everything was fine, but at home the tablet’s sensor did not respond well when charging!

The problem may be not only in the cable, but also in the cord. The original one is short (50 cm) and has filters (round crap) on both ends. This protects your phone from interference. Ordinary even branded USB cables (from other branded devices) may not have them, which is why all the problems.

I have a Samsung Galaxy S2, while charging it sometimes (???) gets very hot. It even happened that, having become so hot, it did not react in any way to pressing the ON button, or to the three buttons at the bottom of the screen, or to touching the screen with a finger. I had to disconnect it from charging, remove the battery, then insert it again - then the phone turned on. Okay, I've gotten used to it. But another problem appeared - someone is calling me or the alarm clock is playing, or I just want to unlock the screen... the screen does not respond at all to my finger touches! At the same time, the phone is in my pocket, on the table in the office, and in other places, fully/half charged and not connected to the charger. It's like the screen doesn't feel my finger. Even connecting to charger and/or to the USB cable does not help. I have to press the ON button 5-8 times, but even this sometimes doesn’t help. In a hopeless situation, I simply take out the battery and insert it again. I don't know the cause of this problem. Has anyone encountered this and solved it?

PS. Probably the best solution is to buy a new phone. But why buy an expensive phone then, if in 8 months it will also be so buggy? I even began to rave - are phone manufacturers really doing this on purpose? After all, new models appear on sale precisely when we are faced with problems with existing phones...

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 is completely unresponsive to touch, this is probably due to mechanical damage, for example, when falling. 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 the glitch operating system It may turn out to be a banal 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, no infection for mobile devices did not exist, 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 properly?

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 it for 10-15 seconds. Home buttons and inclusions. 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, protective glass microcracks appear, 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.

e under Android control. The touchscreen (sensor) works on its own, it works some time after pressing, it is dull, lags, and does not work correctly. What to do and how to fix it?

Many users encounter a problem when phone or The Android tablet starts acting up. It seems that it didn’t fall anywhere and wasn’t “watered” with anything, but it doesn’t work as it should.

For example, the device has problems with a touchscreen, i.e. touch input (“sensor”) does not work correctly. The reason for this may be:

1st: Software glitch - i.e. the problem is the crash software

2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

However, do not rush to get upset - in 90% of cases there are problems in the operation of touch input (touchscreen) smartphone or Android tablet is to blame software glitch which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings", find there « backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.

Method 2.

Based on solving touchscreen problems phone number and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. Best monitors system functions, corrects, and corrects all possible settings and synchronization errors, small and easy to handle, free utility for Android devices. Download the app from Google Play and you can see its additional options in the description. After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)

Method 3.

Changing the device software, or as it is also called "re firmware ". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.
