Modern Gadgets have become an integral part of our lives. The phone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water or software glitches. The most common problem that many mobile device users face is that the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact service center. Otherwise, do not rush, because there are times when the problem can be easily and quickly fixed. The sensor does not respond to touch, what should I do in this case? Let's look at all aspects of this problem.
phone screen repair
Before solving the problem, you need to make sure what is the cause of your display failure. This may be mechanical damage, liquid getting inside the device or software failure. If you are sure that you did not drop your phone or spill liquid on it, then you can assume that this is a software glitch.
Mobile phone screen cleaning
First, you can simply clean the display of your device. You will not harm the phone in any way, but improve the connection and perhaps the problem will be solved. This method can help if the sensor does not respond to touch. What to do?
We take a suitable cloth and liquid to clean the screen. It is better to use a lint-free or any other natural fabric. To clean the display, we need an eyeglass or monitor cleaner.
If this method does not help, then you should proceed to the next steps. Of course, they can't help either. The true cause of the breakdown can only be established by a professional, but he can not solve every problem.
A software glitch that caused the display to break
If the display of the mobile device reacts in places to your touch, then you can try to do hard reset systems, it full reset settings. But it is worth remembering that this can only help if the sensor is buggy from time to time. After resetting the settings, install applications that can clear system registry. This will eliminate errors caused by RAM. Recommended applications are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but has good functionality. The first program is for you if you are not sure about the reason why the display does not respond well to touch, and you are not going to spend money.
All actions should be performed without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card back in place and check the device with an antivirus. Select full device scan and wait. But even after the actions taken, the sensor does not respond to touch. What to do? In this case, it is necessary to proceed to the replacement of the sensor, since the cause is not caused by a software failure.
Mobile phone display replacement
The sensor does not respond to touch - what to do? If previous ways did not help, then you need to change the damaged display. Most often, this should be done when the device has fallen, cracks have appeared, or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. Thus, the condensate that accumulates in mobile device, will interfere with the normal operation of the phone. At first, black spots may appear when working with the gadget, and later the sensor itself will stop responding to touch. In this case, you will need to change the screen.
Repairing a phone screen is not a very complicated process, the main thing is attentiveness and accuracy. This can be done by anyone. The sensor does not respond to touch - what to do? First you need to disassemble your device, but you should remember the sequence of actions so that there are no problems with assembly in the future. All plugs and latches are removed with a thin object. You will need to carefully remove all the elements from the latches with this object.
After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, because when ordering a new screen, this aspect will need to be specified.
The sensor can also be connected to printed circuit board different ways. There is a contact method, while the sensor is simply disconnected, and wired. In the latter case, you should be very careful.
If you need to detach the matrix from the sensor, you must follow these recommendations:
- First, heat the surface to 60 degrees. This can be done with a regular hair dryer. It should be heated evenly so that the glass does not crack, and the glue heats up.
- Next, you need to find a flat and thin object to easily detach the sensor from the matrix. To do this, simply pry the edges and gently lift.
It remains only to attach a new sensor. How to do it? The kit should include the sensor itself and glue. First, we apply special glue, and then carefully attach the sensor.
The cost of a new display
How much does it cost of course different models smartphones screen cost will be different. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, you will need to pay about 700 rubles.
If you do not want to disassemble the phone yourself, then you can contact a specialist. For the master will ask about 2000 rubles. Although this procedure is not very complicated and you can change the screen yourself. Only this will need to be approached carefully and carefully.
Touch buttons not working
Lower touch buttons are directly related to the screen and in case of their failure, it is necessary to do all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clean the system registry and check your device for viruses. Unfortunately, if the steps taken do not help, then it will be necessary to change the screen.
Modern touch Cell phones- a universally recognized attribute of our life. Their rich functionality and wide capabilities allow them to be used to solve a variety of tasks that are not limited to classical phone calls. The richness of options for using such devices leads to their gradual failure, and one of the most common failure options is sensor dysfunction on the phone, when the latter simply stops responding to pressing (or reacts extremely poorly). In this article, I will tell you what are the causes of such dysfunction, and what to do if the sensor on the phone does not work.
Causes of phone sensor failure
Consider the most common reasons for the failure of the phone sensor. They may be as follows:
The sensor on the phone does not respond what to do
To restore the normal functionality of your phone's sensor, do the following:
*#7353# - for most Android phones, especially Samsung;
*#*#3424#*#* - for most HTC phones;
*#*#7378423#*#* - for most Sony Xperia phones;
*#0*# - for most Motorola phones.
In the menu that appears, select, for example, "TSP Dot Mode", and by clicking in different areas of the screen, see which parts of the sensor are not interrogated, this can help fix the problem that the touchscreen does not work.
Restoring the sensor through safe mode
To boot into safe mode turn off the phone completely (including by removing the battery). Then long press the Power button to turn on the gadget. When the logo of Samsung, Nexus, LG, etc. appears on the screen, release the power button, and then hold down the Volume Down button. Press this button when your device boots up, and you will see the inscription “Safe mode” at the bottom left of the screen.
Conclusion
If the sensor on your phone does not work for you, then I recommend using the tips I listed above. If it is impossible to identify the specific cause of the breakdown, I recommend that you contact your gadget with a service center - it is quite possible that your device will need a complete replacement of the touch panel.
There is a function Assistive Touch- so restart the gadget with the broken key " power' is quite simple. However, if the sensor is out of order, turning off the iPhone is more difficult: you have to resort to hard reset– an operation that could harm the device.
The need to turn off the iPhone without a swipe on the screen, as a rule, occurs when the device freezes during installation mobile application. The sensor also fails due to physical impact- for example, after the gadget falls to the ground. Most users, when the sensor hangs, immediately turns to warranty repair, not suspecting that you can do without a 45-day wait and fix your smartphone yourself.
The probability that after a reboot a frozen sensor will “resurrect” is 90%. But since the screen does not respond to touch, turning off the smartphone in the usual way will not work - you will have to hard reboot. It is done like this:
Step 1. Hold down two physical buttons at the same time - " power" And " Home».
Step 2. Hold them until the Apple logo appears on the screen - about 10 seconds.
Then release the buttons.
Step 3. Wait 4-5 seconds and you will see the desktop of your mobile device.
On the iPhone 7, instead of the "Home" button, you need to hold down the volume down key.
How to turn off the iPhone if the sensor does not work?
If you just want to turn off the gadget, and not restart it, you should proceed a little differently:
Step 1. Press " Home» + « power».
Step 2 Hold the buttons for 4-5 seconds - until the screen goes blank - then release them. Don't wait for the "bitten apple" to appear!
After that, you can turn on the smartphone in the usual way - by holding the "Power" button for 2-3 seconds.
By "hard reset" not only the problem with the sensor is solved. TO hard reset also resorted to if the iPhone has become poorly catching the network or consuming too much energy.
Possible consequences of rebooting without using the sensor
If apply hard reset once or twice, negative effects definitely won't. If you constantly resort to a “hard reset”, there is a risk that the memory module will fail, as a result of which all data stored on the iPhone will be lost. There is a widespread opinion among users: each subsequent hard reset increases the likelihood that the memory will "fall". However, this has not been confirmed by experts.
You should resort to a “hard reset” only as a last resort - when other methods to solve the problem have already been tried and have not brought any result.
Conclusion
“Hard reboot” is the simplest and fastest measure aimed at returning the sensor to working capacity. But not the only one. If the user is afraid to hard reset, he can refer to iTunes- the media combine will restore the device, and along with the restoration, the gadget will also reboot. There is an option for the most cautious users: wait until the smartphone is discharged and turns itself off, and then “start” it in the usual way.
Every owner of a smartphone or tablet immediately after purchase is very happy with the speed at which his device works. All operations are performed quickly, responses to touch are timely and without glitches with pictures. But over time, everything changes and performance deteriorates. Why does Android slow down?
Among the reasons that Android slows down or freezes, there are several main ones:
- slowdown can cause a large number of simultaneously running applications, albeit in the background;
- due to a recent update, a smartphone that has not slowed down before may start to do so;
- any device can freeze even when it starts to run out of free space;
- a small amount of RAM can even cause the gadget to spontaneously reboot;
- sometimes the phone can fail due to problems with the touchscreen.
What to do if the phone began to slow down for one of the listed reasons?
Troubleshooting
Application cleanup
When the phone started to slow down a lot due to gluttonous applications and background processes, then to correct the situation you need:
- hold down the menu button, a list of recent ones will open running applications, select "Delete all";
- in the Application Manager, view the list of those running (opposite each, the operating time and the amount of RAM it occupies) and stop forcibly each unnecessary at the moment;
- in addition, you can remove live wallpapers and widgets, which also greatly affect the productivity of the device;
- applications that the owner of the gadget does not use should be deleted altogether in order to avoid running their processes in the background in advance.
Rollback update
Why does the device slow down after the update? The fact is that over time, any smartphone or tablet becomes obsolete, and each a new version Software or Android with its add-ons requires more and more powerful stuffing.
In this case, you will have to reflash your gadget with a return to the previous, workable version. You can do this in two ways:
- Through recovery. First you need to download the required firmware version to your phone and save it on a memory card. Then enter Recovery (more often with a combination of the power buttons and the volume rocker down). Next, install the downloaded update and reboot the phone.
- Through a computer. For this you need to download setup file from the official website of the manufacturer and using the software supplied with the phone (usually on a disk), install it on a gadget connected to a PC.
After that, it is desirable to disable the function in the phone. automatic update system so that you do not have to repeat the procedure. It should also be remembered that after flashing from the phone, all data may be lost, therefore it is better to make a backup first.
Free up internal memory and storage space
When the device runs out RAM, it tries to make up for it at the expense of internal memory. If its volume is too small, the phone may refuse to perform any actions. In this regard, you need to periodically perform the following actions:
- clear the cache of the system and applications;
- resorting to special applications, clean the system itself (this will end background processes);
- synchronize media files on the "cloud" or with another drive and clean up from your device;
- do not forget to carry out the same actions with a flash drive, because. small volume free memory it also affects the performance of the device.
Sometimes at the end of the RAM it is enough and just to reboot the phone.
Screen calibration
What to do if the sensor on the phone is buggy? In this case, you need to configure the problematic display to correctly execute commands after swinging your fingers or stylus. Otherwise it is called screen calibration.
This need arises more often after mechanical damage or contact with water. And to be sure that it is the sensor on Android that is the problem, you need to:
- remove the film;
- on the keyboard, try to enter any character.
If another number or letter pops up, the touchscreen will have to be calibrated. You can configure the sensor sensor using special programs(eg Touchscreen Repair), or manually. In the Play Market you can find a large number of necessary applications, and free ones.
Self-calibration is carried out as follows:
- in the phone settings, go to the "Display" tab;
- find the item, the name of which will be "calibration";
- put the phone on a flat surface and press calibrate (in some models, the phone will offer a target, in the center of which you need to hit at least 3 times);
- reboot the gadget and check the response again.
