e running Android. The touchscreen (sensor) works by itself, works some time after pressing, dulls, lags, does not work correctly. What to do and how to fix it?
Many users face a problem when phone or android tablet starts to play up. It seems that he did not fall anywhere and did not "watered" with anything, but it does not work as it should.
For example, the device has problems with a touchscreen, ie touch input ("sensor") does not work correctly... This could be due to:
1st: Software glitch - i.e. the problem is a software failure
2nd: Hardware failure - i.e. the problem lies in the "hardware" (that is, it requires replacement or restoration of spare parts for the gadget)
However, do not rush to get upset - in 90% of cases with 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"where you choose full reset settings with deletion of all data. Be careful, the use of this method is often effective, but it entails the deletion of 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 the problem persists after it, see Method 2.
Method 2.
Based on solving touchscreen problems phone s and android tablets by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all controls system functions, corrects, and fixes all possible settings and synchronization errors is a small and easy-to-use free utility for Android devices. You can download the application from Google Play and see its additional options in the description. After installing the application, all that remains is to launch it. Further, from you, in principle, nothing else is required. The application will completely take over the control of the device's functions. (By the way, among other things, the gadget will start charging 20% \u200b\u200bfaster, and its performance will also significantly increase, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)
- In addition, it is worth cleaning the system with NORMAL antivirus. Best of all, it copes with this task kaspersky antivirus , which you can download. Unlike the "multi-cleaner", the software of "Kaspersky Lab" is paid, therefore, if you do not have the opportunity to install such protection, you can skip this step ...
Method 3.
Change of device software, or, as it is also called "Per firmware ".This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer's website for your device, download the utilities and the firmware itself necessary for the firmware, and then reinstall it on your gadget.
If none of the methods brought results, unfortunately, you will have to contact the Service Center for repair of your tablet a or smartphone a.
The touchscreen (sensor) does not work well in a phone or tablet running Android. The touchscreen (sensor) works by itself, works some time after pressing, dulls, lags, does not work correctly. What to do and how to fix it?
Tablet computers have become faithful companions for many people. They allow you to view email, work with documents, play games, listen to music and perform other actions, by analogy with a regular computer. An unexpected breakdown of the tablet literally unsettles, forcing users to look for the reasons for its breakdown. My tablet doesn't respond to touch - what should I do?
If your tablet isn't responding to touch, it could mean anything:
- The software has hung;
- The screen itself is out of order;
- Electronics broke.
There are many other reasons for touchscreen breakage as well. For example, some cheap Chinese tablets with resistive screens suffer from loss of sensitivity quite often. And if you happen to buy such a tablet, be prepared for any malfunctions, even if they go beyond logic.
So how do we restore the sensitivity of a resistive touchscreen? First you need to connect a mouse to the tablet and make sure that it moves. This means that the device is not frozen. Next, go to the screen settings and calibrate it - you will find the corresponding item in the settings.
The essence of calibration comes down to pressing the points indicated on the screen (it is best to tap with a stylus or any other not very sharp object). After completing the calibration, the tablet can be restored to work.
Calibration will not be possible if the display itself, which is responsible for the perception of touch, is out of order.
If the device still hangs, you will have to restart it - for this we hold down the power button or press the reset button with a needle (if there is one). After a reboot, the system should recover.... That did not happen? Still not responding to your screen? Then you will have to give the tablet to a repair shop, where specialists will take care of it.
Do not try to repair tablet PCs yourself without proper knowledge and tools. Even if you manage to disassemble the tablet, then you may not see any traces of damage inside - it is better to entrust the repair to specialists.
Recovering tablets with capacitive screens
If your tablet screen isn't responding to touch, it's likely that it just hangs. The device just needs to be rebooted by holding down the power button - after a while it will reboot, even without confirmation. If this did not help, you should figure it out, after which this trouble appeared.
For example, an unexpected loss of sensitivity can occur due to some software that was installed shortly before the breakdown. We can do the following:
- Try to connect the mouse and remove the last software, then send the device to reboot;
- Restart the tablet in safe mode, when only system utilities, drivers and programs are loaded into memory.
Removed the last installed programs and the screen is working again? This is possible when certain applications enter into conflicts in the system. To prevent the malfunction from reoccurring, do not install remote programs or try to find their analogues.
Note that support for external input devices, such as wired and wireless keyboards, mice, joysticks, and gamepads, is not available on all tablets. Instructions for inserting tablets into safe mode you can find it on our website - we already did a review on this issue.
If your tablet stops responding to touch, you can try removing the protective film from the screen. Some films, having a significant thickness, become an obstacle to the functioning of capacitive screens. The use of such films should be avoided despite the significant protection they provide to the display.
Does the tablet screen stop responding to touch after being hit or dropped off the table? Take the device to a repair shop for an experienced technician to inspect it - an independent repair is not possible here.
Filled your tablet with water, juice, milk, or any other liquid? This is another reason to visit the service center - here the tablet will be washed, cleaned and restored to its former working capacity. The most exotic repair method is to turn off the tablet and wait a few hours. Oddly enough, it sometimes helps.
It is possible that the fault is some kind of software malfunction or overheating of the electronics. If the manifestation of this malfunction is regular, try contacting a service center where professionals will take care of the tablet.
An extreme measure that allows you to count on the restoration of the touch screen is a full reset, which can be done through Recovery Mode (we have already studied ways to enter this mode in our reviews).
If the sensor on the tablet does not work, the cause may be hardware or software. But only in rare cases can the user solve the problem himself. Consider all situations, their features and possible troubleshooting methods.
The touch screen is one of the most vulnerable parts of tablet devices. Anything can affect its work, but here are the most common reasons influencing the touchscreen and its performance:
- mechanical damage - as a result of a fall, the contacts connecting the screen to the board could come off;
- software glitch - if the user changed the firmware or did it in service center, various operational errors will be constantly monitored, they can affect the operation of the sensor;
- calibration failure - this applies more to older devices with resistive displays, the calibration will have to be re-configured through the tablet operating system;
- ingress of water - moisture leads to oxidation of the contacts and can cause more serious damage, therefore, in this case, it is impossible to use the equipment until a complete check;
- factory defect - such a defect is detected immediately and must be eliminated according to the rules of warranty service (the tablet can simply be replaced in the store where the purchase was made).
These are the most common problems that happen with tablet devices. But if it is easy to cope with mechanical damage and hardware breakdown, then software failures require the intervention of experienced craftsmen.
What to do to fix the breakage
In most cases, the user cannot restore the correct operation himself if the tablet does not respond to touch. But there are measures that can prevent the occurrence of more serious problems:
- when drowning, it is necessary to disassemble the device as much as possible (if the design allows it) and dry each individual part in a towel that absorbs moisture well - for this you need to turn off the tablet and, if possible, remove the battery from it;
- mechanical failure also requires disconnecting from the network and deactivating the battery - in such a situation, it is better not to use the tablet.
With software glitches, things are a little easier. The user can resort to rebooting the system and "fix" the screen.
Fixing System Crash Using Hard Reset
A forced reboot can be done on any device. A forced reboot is provided by manufacturers in case operating system will stop responding to user requests. This is especially true for tablet devices that operate primarily through a touchscreen. If the OS does not find it or any settings that are responsible for interacting with this component are lost, it is necessary to "reset" the failure and update the ongoing processes.
For a forced restart, you must hold down the Home key (or Power - depending on the model) with one of the volume keys. Usually, the technical documentation for the device contains combinations with their descriptions, so you need to read the information from the manufacturer.
After pressing the buttons, the system logo will appear on the device screen - Android or iOS. The reboot process may take longer than usual, but the result will be to restore the OS and the tablet will work fine.
If this method does not work, you need to contact a good service center, but do not try to solve the problem yourself. User intervention can lead to even greater disruptions.
How to fix a tablet - all methods
If the breakdown is insignificant or it was not preceded by any mechanical damage and flooding, you can try:
- remove the protective film or glass, if any - sometimes the protective layer on the screen is too low-quality or wears out faster than necessary, making it difficult to access the sensor, which makes it seem that it does not respond to touch;
- wipe the screen - sometimes it is quite dirty and the accumulated layer interferes with the normal response to user requests;
- if the screen stops responding, you need to try to charge the device - the system may experience malfunctions due to which the tablet distributes energy incorrectly or does not perceive the exhausted charge, continuing to work in standard mode.
Most often, the tablet can only be repaired at a service center, since the user himself, without special knowledge, can aggravate the problem.
What to do to prevent the problem from recurring
- Do not interfere with the firmware of the device - any unauthorized software changes entail failures and errors in the system;
- Do not use non-original components - be it a charger or any part that had to be replaced, the use of functional elements from other manufacturers may cause damage to the device;
- Do not try to disassemble the tablet - technical intervention, especially if the user does not have the appropriate knowledge, it can violate the integrity of the components.
Any technique requires a careful attitude towards itself. Tablet devices are extremely fragile, since most of their construction is occupied by the screen. Any mechanical damage can lead to damage. But this also applies to software interventions - attempts to reflash the OS lead to numerous operational errors.
The touch display often fails, being one of the most vulnerable components of tablet devices. But quite often the reason for this is mechanical failure or violation of operating rules. In order not to aggravate the problem, you need to contact a good service center for timely repairs.
A tablet is a device that allows you to go online, call friends, play games, watch videos and listen to music. The gadget is very popular due to its compact size, light weight, fast Internet connection, accessibility and ease of use. Thus, a smartphone and a computer are combined in one device. Since the tablet is always in working order, it is not surprising that its components fail. Most often, the tablet sensor breaks down. There may be several reasons: electronics breakdown, poor quality software, mechanical damage. If it is necessary to order the repair of TV in Kharkov, tablets and monitors, we recommend SC "Solaris".
How to keep the tablet screen intact?
Modern tablets are light in weight and very thin, therefore their screens are rather fragile. That is why you need to work carefully with your gadget. If you drop it slightly, the screen will not crack completely, but small cracks may appear, and dust will start to clog in them. In addition, the screen can crack due to temperature changes, excessive pressure. To keep the device intact, adhere to the following expert recommendations:
- do not carry your tablet in a bag without a protective case. It is better to give preference to hard products;
- stick a protective film on the screen surface and change it periodically. The service life of a good film is more than one year;
- do not leave the gadget on chairs, armchairs and sofas;
- do not put into the hands of people who have not previously used such a device, keep it away from small children and animals.
Screen cracked, what should I do?
If the tablet could not be saved and it cracked when it fell, then you do not need to despair right away. To begin with, experts recommend that you figure out what exactly broke and why the sensor does not respond to finger touches. The tablet screen consists of a matrix that transmits the image and directly a glass screen, which is also called a touchscreen. If only the glass screen is damaged, it can be easily repaired. You go to the workshop and the master replaces the glass with a new one. This service will not cost much. The link can be used to find out the prices for the repair of the LCD screen of the tablet in Kharkov. But if the matrix received damage, then the repair will cost many times more.
Determining if the matrix was damaged when the tablet was dropped is quite simple. If it is in working order, then a crack will be visible on the screen, but the gadget itself will continue to work as usual. But there is a risk that the damaged glass will damage the matrix over time. This, although rare, does happen. In addition, the sensor will not work correctly on a broken screen. That is why you should not delay your visit to the service center.
Of course, replacing the matrix will be expensive. In many tablet models, the matrix and touchscreen are non-separable units, so both will have to be replaced. If the glass of the tablet did not break during the fall, but the touchscreen stopped working, then, most likely, the train came off and a microcrack appeared. In this case, you will need to disassemble the device and check the signal. If the screen reacts to touches only in a certain area, then either the touchscreen or the module will be subject to replacement. The appearance of spots on the display also indicates its damage.
Since gadgets tend to fail at the wrong time, many users try to fix them at home. We do not recommend doing this, since such an undertaking is not always crowned with success. At home, you can reboot the device, adjust the touchscreen, or clean the screen from dust. Note that an unsuitable charger and poor quality screen protector can reduce the sensitivity of the touchscreen. It is better to entrust repairs to specialists. In Kharkov, the repair of the monitor screen and tablets can be entrusted to the aforementioned SC "Solaris".
First, let's define why the sensor on the tablet does not work?
Tablet sensor not working?
We constantly print, enlarge, draw with our fingers “patterns” of rare “beauty” - all these actions are common to every person, and that's why we buy tablets. But sooner or later, we face a problem when the sensor on the tablet stops working, regardless of whether Lenovo at you or Samsung Galaxy Tab, iPad or Prestigio!
The touch display is the primary way of interaction between you and your installed applicationsand therefore it is a vital component of your tablet. Any damage caused, even the slightest scratch, will degrade component reliability, and after a certain time, one way or another, you will face a problem when the sensor on your tablet no longer works!
What can be done if the sensor does not work on the tablet?
The following advice, in part, will help you solve the responsiveness problems of your tablet's sensor. These tips can be applied to IOS, Android and Windows 8.
1. Need more RAM
Freeing up RAM on iPad
Probably a process restore the tablet sensor the best place to start is by increasing the amount of available RAM. This may take a while (and may require a reboot in some cases), but it should also give us an idea of \u200b\u200bhow bad things are. Users Android have many options to free up tablet memory, such as clearing the app cache or fully optimizing the device with third-party apps such as Memory booster.
Memory problems on iPad can easily slow down the touch screen response. The best way handle this (on iOS 6 and below) double-click the Home button to display the currently open applications, and then press and hold to display the cross in the upper right corner.
If you see improvements in the responsiveness of the tablet senosor while freeing up RAM, then that must be the problem.
If a the sensor on the tablet is still not working, or you are sure that the problem is different, let's look at the following recommendation.
2. Try restarting your tablet
Among other things, troubleshooting can be facilitated by the usual. When the device restarts, most applications will be closed. For Android users, this shouldn't be a big problem - all you have to do is hold down the power button and select the appropriate “restart” action.
Apple iPad owners will need to close all open applications before pressing the Sleep / Wake button.
Windows 8 tablet owners can restart their devices by opening the Charms menu and then clicking Settings\u003e Power\u003e Restart. If the device stops responding, hold the Windows button and the power button together for a few seconds until the tablet restarts.
So, if after rebooting your tablet, the sensor does not work, let's move on!
3. Use the native Troubleshooter apps
Often when tablet sensor is not working, this does not mean that it does not work entirely! The problem may actually only be in some parts of the display.
Knowing which areas of the touchscreen are unresponsive can be very helpful in diagnosing your device; the information will certainly come in handy for any tablet repairman.
Applications such as a calculator and maps are useful tools for checking non-working areas of your display.
So, we tried to describe the 3 most effective methods for fixing some tablet sensor breakdowns that you can use yourself.
However, as you may already be aware, there are problems that are so complex that you may need to have your device serviced. In our service center in Simferopol, specialists are ready to help you even in the most difficult cases.
