Sensor buttons do not work. How to enable on-screen buttons when physical buttons no longer work

Menu button in the phone android samsung and many others, maybe sensory, physical and of course, like almost everything sometimes does not work.

If it is physical, then it is often solved by cleaning the contacts. There seems to be a video on YouTube of how to do it yourself.

If your menu button is part of the sensor and does not work, then this is worse than it would be physical. Such repairs are more expensive.

However, you can try to calibrate the screen of your smartphone - suddenly it will help and will do without repair by specialists.

What to do if the menu button does not work in an android smartphone

From the very first words, I will say right away that it is not easy to fix the problem with a non-working menu button on your own.

However, without it, like some other "home" and "back", "you can live" if you emulate them programmatically.

To do this, you need to get root rights and install the "Floating Soft Keys" program. Then you can adjust the buttons to return your device to proper performance.

Sometimes you may need a new touchscreen, although it can be difficult to find one for certain models.

Sometimes the problem can be solved without opening the case - a duplicate of the function keys, but not on all android devices this will work.

To activate such a function, you need to write the line "qemu.hw.mainkeys = 0" in /system/build.prop at the very end, but superuser rights are required.

As a result, additional functionality should appear above the faulty button. The application "Soft Buttons" can simplify this procedure.

There is a program that does not require root rights, which allows you to duplicate the phone buttons. One of these "Back Button" is free with many settings.

After installation, translucent icons appear on the display with function keys: menu, back, home and screen rotation. They can be dragged to a convenient place, only the screen is reduced to the height of the icons.

Reasons for not working menu buttons in android

This could be due to a software or hardware failure. Fortunately, 90% of the problems in software glitch, which is solved independently.

To do this, go to the "settings" and click on the section " backup and reset ". We choose there full reset settings with the deletion of all data.

Naturally, before that, we separately save everything that is needed (you can on the computer, and then transfer it back to the phone).

You can also use the Turbo Cleaner program. The application is capable of controlling the functions of the phone.

The last option is "flashing", which requires skills and contacting a service center.

If the description above did not bring positive result, then you don't want to, but most likely you cannot do without a service center. Good luck.

There are two types of Android device owners. The first category of users prefers virtual keys, absolutely not recognizing physical keys. The second - firmly believes that the on-screen buttons to control the system "eat up" a fair amount of precious space on the desktop, and therefore a priori have no right to exist. Often absolutely nothing can change the warlike attitude of the latter, except for breakdown.

In order to emulate the functionality of the control keys on the screen, you should install from free app Virtual Softkeys. The utility does not require obtaining root rights, which means that you can use it here and now.

Run the application and give it access to the accessibility features of your device. To do this, go to "Settings" - " Special abilities"-" Services "and activate the work of Virtual Softkeys.

Now you need to return to the application and make the initial configuration: set the transparency of the virtual keys, the time of their demonstration and a number of other parameters.

After completing the necessary settings, close the Virtual Softkeys application and, once on the desktop, make a swipe from the bottom of the screen. This gesture will bring up the panel of virtual keys, it will also allow you to hide them back.

If your touches are already producing the desired effect, if the response time has grown so much that it can be seen with the naked eye, if the phone started to execute commands inadequately, then it's time to ask yourself how to fix the sensor on your phone. In principle, this is either done very simply, or is not possible in principle, and you are dealing with the need for a complete replacement. But this is another story.
There are a number of identifying signs here so as not to be mistaken:

• Problems build up gradually, possibly in a gradual manner;
• The sensor is equally clumsy in all parts of the screen;
• There were no hard shocks, drops into water, extreme temperatures and changes;
• There are no cracks or damage, or they appeared later.

Be that as it may, ideally it is still worth carrying out diagnostics in order to be sure of the type of breakdown.

How to fix a sensor on a phone at home with experience?

The main rule in this case will be a thorough preparation of the workplace and the necessary tools. The order of work is as follows:

• Disassemble the case, remove the screen and release the sensor if it is not integrated;
• You clean the contacts, press the sensor contact to them, apply power and check the result;
• If you are lucky and everything works - we fix the contacts with a dielectric and assemble;
• If not, we look for the problem further or ask for help.

All safety rules are simple and intuitive, so we will not focus on them separately, but it is vitally important to comply with them.

How to fix a sensor on your phone with your own hands for the first time?

Do not panic, as stated in the pages of the Guide. Everyone started sometime, and as a result, many of them have achieved success, which means you have a chance. Collect all the data about the device, watch the repair videos, find the aspects that you do not understand and clarify them. If you feel ready, proceed. In the end, after all, if you do not take information that can be discarded in advance, you risk only money, and this loss is not irreplaceable.

The sensor is not such a complex and delicate module that only a select few can do its simple repair. When contacting professionals, you will receive a guaranteed result, no worries, and the costs will not be critical. You can independently work with phones of any brand and model, whose design you know. There is no definite answer, which is easier, to restore a classic mobile phone battered by life or a modern modular smartphone. One thing is for sure - the road will be overcome by the one walking!

The touch screen of a smartphone provides the user with much more control over the phone than with physical buttons.

But, unfortunately, the failure of touch buttons is not so rare, and in terms of reliability, they do not surpass ordinary buttons in any way. Find out what to do if the touch buttons on your smartphone do not work and why this happens.

The simplest reason is dirt

The sensitivity of the sensor in a smartphone directly depends on its purity. If you touch the screen with dirty hands, particles of dirt adhere to the glass and then reduce the sensitivity of the sensor to the point of complete failure.

To return the touch buttons to their normal state, it is enough to wipe the screen with a damp cloth designed specifically for cleaning monitors. To prevent frequent contamination of the screen, you can use a protective film, which will not only prevent unwanted substances from sticking to it, but also protect it from scratches and small cracks.

Inaccurately glued film

Sticker protective film- it's not easy. There should be no air bubbles under it, otherwise some touch buttons will not be able to fully function.

Many phone owners undertake to stick the film on their own, but later they are forced to contact service specialists about this, since due to the poorly glued film, the sensitivity of the sensor deteriorates and the buttons do not work.

Temperature imbalance

Failures of touch buttons due to inappropriate temperatures are most common in winter, when the thermometer drops below 10-15 degrees below zero. The LCD screen of your phone is sensitive to low temperatures and may not function as required if it gets cold.

If the exposure to low temperatures was short-lived, after warming up, the phone will quickly return to normal performance on its own.

The touchscreen has shifted or is peeling

If the phone is operated in hard mode, and its owner constantly exposes delicate techniques to various negative influences, the touch panel or touchscreen may peel off the screen in some places. If this happens at the bottom of the smartphone screen, the function touch buttons may stop working.

To get rid of this problem, you should warm up the touch panel with hot air to soften the special glue that attaches it to the screen. Better not to try to do it yourself, so as not to worsen the situation even more. Contact the specialists from the service center who have experience and the necessary equipment for such manipulations.

Software glitch

If a Touchpad shines clean, and even the most careful inspection does not show any damage, but the touch buttons still do not work - perhaps there was a software failure on the smartphone. Restart your operating system by turning off your phone and then turning it back on.

This is usually a simple step to fix random errors. If this did not happen, remember - you may have installed a new application or updated some of the already installed applications before the touch buttons failed. Sensor failure can be triggered by a software conflict between old and newly installed utilities. Delete the new application and restart your smartphone - it is possible that the touch buttons will restore functionality.

Viral contamination

The ubiquity of smartphones has forced the attention of virus-writing hackers to this segment of software. Today, antivirus software on a smartphone is the same essential piece of software as on a regular computer.

If you do not have antivirus protection, it is possible that the failure of the touch buttons is caused by the actions of a malicious program. Download a good antivirus and scan your phone, then ruthlessly delete any files that seem suspicious.

Reset

If none of the above measures worked, you are left to try the last remedy available to the average user. Factory reset your phone.

If the failure of the touch buttons was caused by any programmatic reasons, as a result of the reset, all errors will be reset along with your personal settings, application updates, and the applications themselves installed during the use of the phone. After the reset, the functioning of all elements of the phone is resumed in the vast majority of cases.

Custom firmware

If you have installed the so-called custom firmware on your phone, then you should be aware that from now on the manufacturer is not responsible for its performance.

Often, the consequence of such actions is the failure of any functions. What is most offensive, you don't even have anyone to make a claim. The only way out is to return to the factory firmware, which can be downloaded from the website of your phone manufacturer.

Everything and always breaks down unexpectedly. Dropping your phone on a tiled floor is an annoying accident, drowning it in a bathtub is a commonplace that occurs more often than it seems at first. Statistics of calls to service centres contains many complaints about accidents from the series "it fell and crashed" even more often than drowning. At the same time, one should not expect that the very first fall will take away the sensor substrate or even the screen itself - in most cases the consequences of annoying accidents do not look so destructive. Among other things, this is the sudden inoperability of the physical buttons "back, home and menu." If this trouble happened to your phone, and there is still no money for repairs, do not worry. There is a relatively simple solution to this common problem. Now we will teach you how to turn on the onscreen buttons on your smartphone if the physical ones no longer work.

For everything to work out, you need to get Root rights... Administrator access to the depths of system files is sometimes difficult to get. But with the advent of apps that get the access they need for you, you no longer need to read multi-page instructions. Just install Kingo Root software on your computer and connect your phone. The only thing that needs to be done while the program is being installed is in the phone settings, in the "security" section, to enable "USB debugging". That's all. By clicking the big Root button in the interface Kingo root, activate administrator rights.

Step two looks a little more complicated. You will need to download from Google play(or a little ... alternative sources) the Root Explorer program. Install it on your smartphone. Run this application, find the System directory, and in it - build.prop. If such a file is not visible in the system directory, it does not matter. IN upper corner programs have three dots - tap on it to open a submenu. In the program settings, check the item "Show hidden files". The loss will immediately be revealed.

In the left corner Root Explorer there is one more item we need - r / w. Tap it once and confirm your choice. This action activates the ability to edit system files... Now tap and hold build.prop on it. The top menu will change and from the drop-down list (in the same ellipsis) you will find the "open in a text editor" sub-item.

Scroll open file all the way down - all those long lists of settings are not needed yet. At the very bottom add the line qemu.hw.mainkeys = 0. Save the file and restart your phone.

Done, at the very bottom of the screen there are three on-screen buttons - similar to what you can see on the screen of any tablet. And after repairing the physical buttons, the virtual ones can be completely hidden back by replacing the line qemu.hw.mainkeys = 0 with qemu.hw.mainkeys = 1 and restarting the device again.

Eliminating the problem at home

A common reason for the failure of all buttons is a long stay of the smartphone in a damp place or a strong impact. In the first case, the contacts could oxidize and the problem can be solved by cleaning them. In the second case, you will need to diagnose the device, which we advise you to entrust to the engineers of the HTC smartphone repair center. What to do if you want to eliminate the problem yourself, and the reasons for its occurrence, read below.

How to fix the problem

1. Determining the state of the buttons. In order to understand how serious the problem you are facing, it is necessary to determine whether the lower buttons respond to touch. To do this, you need to enable a function called "Vibration confirmation". To activate it, go to the "Settings" - "Sound" menu, and at the very bottom of the list that appears, check the box next to the "Vibration confirmation" function.

Your smartphone should now vibrate every time you press the bottom buttons. If this happens, go to the next step. If not, try steps 3, 4 or 5 of this instruction.

1. Calibrate the screen. To do this, go to Settings - Language & Keyboard - HTC Sense Input.

Select " Additional settings"-" Calibration tool ". After that, a proposal will appear on the screen, which must be typed on the keyboard. Follow the green circle.

If you fail to calibrate the keyboard, or you do it incorrectly, then go to "HTC Sense Input" - "Additional settings" - "Reset calibration". This will reset the screen calibration to the factory settings. Then you can perform the calibration again.

1. Software Update. Possibly a problem with non-functional buttons is outdated software your smartphone. Update the software, this method often helps.

1. Soft reset to factory settings. Having previously saved all data from internal memory smartphone to removable media, reset the device to factory defaults. We recommend resetting only to those users who could not fix the problem with the two previous methods. To reset the settings, go to the menu "Settings" - "Memory" - "Reset to factory settings".

Then a menu will appear in which we select "Reset phone settings" - "Erase everything".

1. Hard reset to factory settings ( this way will be useful for those users who do not work with touch buttons and have similar problems with the touch screen). Save all personal data from your phone to removable media beforehand. Now press and hold the volume down button. Without releasing it, press and hold the power button. Release both buttons after the splash screen appears on the screen. The menu that appears is controlled by the volume down and up buttons. Pressing the volume down button select "Restore original settings" (eng. " Factory reset"). Press the Power key to confirm your choice of action.

If the above methods did not help you - make sure that you followed all the steps correctly and sequentially, try to do each step again. Also remember that the bottom buttons are often faulty. HTC smartphones manifests itself due to a faulty display module or hardware problems in the device.
