The menu button on the smartphone does not work. Some buttons on the touch phone do not work

Owners of devices running Android OS are divided into two types. The first category of users prefers virtual keys, absolutely not recognizing physical ones. The second – firmly believes that on-screen buttons to manage the system, they “eat up” a fair amount of the precious space on the desktop, and therefore a priori have no right to exist. Absolutely nothing except a breakdown is often capable of changing the militant attitude of the latter.

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

Launch the app and grant it access to your device's accessibility features. To do this, go to “Settings” - “ Special abilities» - “Services” and activate Virtual Softkeys.

Now you need to return to the application and perform initial setup: set transparency 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, swipe from the bottom edge of the screen. This gesture will bring up a panel of virtual keys, and it will also allow you to hide them back.

Everything always breaks unexpectedly. Dropping a phone on a tiled floor is an unfortunate accident; drowning it in a bathtub is a banality that occurs more often than it seems at first. Statistics of calls to service centers contain many complaints about accidents from the “it fell and broke” series, even more often than drownings. At the same time, you should not expect that the very first fall will take away the touch substrate or even the screen itself - in most cases, the consequences of unfortunate accidents do not look so destructive. Among other things, this is the sudden inability of the physical back, home and menu buttons. If this problem happened to your phone, but you still don’t have money for repairs, don’t worry. There is a relatively simple solution to this common problem. Now we will teach you how to enable on-screen 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 obtain. But with the advent of apps that get the necessary access for you, you no longer need to read multi-page instructions. Just install the Kingo Root program on your computer and connect your phone. The only thing you need to do while the program is being installed is to enable “USB Debugging” in the phone settings, “Security” section. That's all. By clicking the big Root button in the interface Kingo Root, activate administrator rights.

Step two looks a little more difficult. You will need to download from Google Play(or a little... alternative sources) Root program Explorer. 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 doesn’t matter. There is an ellipsis in the upper corner of the program - tap on it to open a submenu. In the program settings, check the “Show hidden files" The loss will be discovered immediately.

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

Scroll open file to the very bottom - all these 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, three on-screen buttons have appeared at the very bottom of the screen - similar to what you can see on the screen of any tablet. And after repairing the physical buttons, it will be possible to hide the virtual ones back by replacing the line qemu.hw.mainkeys=0 with qemu.hw.mainkeys=1 and rebooting the device again.

Troubleshooting at home

A common cause of failure of all buttons is the smartphone being left in a damp place for a long time or a strong impact. In the first case, the contacts may have oxidized and the problem can be solved by cleaning them. In the second case, you will need to diagnose the device, which we recommend entrusting to the engineers of the HTC smartphone repair center. What to do if you want to fix the problem yourself, and the reasons for its occurrence, read below.

Solutions to the problem

1. Determining the state of the buttons. In order to understand how serious the problem you are facing is, you need to determine whether the bottom 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 “Vibrate confirmation” function.

Your smartphone should now vibrate every time you press the bottom buttons. If this happens, proceed to the next step. If not, try steps 3, 4 or 5 from these instructions.

1. Screen calibration. To do this, go to the “Settings” menu - “Language and keyboard” - “HTC Sense Input”.

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

If you can’t calibrate the keyboard, or you do it incorrectly, then go to “HTC Sense Input” - “Advanced settings” - “Reset calibration”. This will return the screen calibration to factory settings. Then you can perform the calibration again.

1. Software Update. The problem with non-working buttons may be due to outdated software on your smartphone. Update the software, this method often helps.

1. Soft reset to factory settings. Having previously saved all data from internal memory smartphone on removable media Reset your device to factory settings. We recommend performing a reset only for those users who were unable to fix the problem with two previous methods. To reset the settings, go to the “Settings” - “Memory” - “Reset to factory settings” menu.

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

1. Hard reset to factory settings ( this method will be useful for those users whose touch buttons do not work and have similar problems with the touch screen). First save all personal data from your phone to removable media. Now press and hold the Volume Down button. Without releasing it, press and hold the Power button. Release both buttons when the splash screen appears. The menu that appears is controlled using the volume down and up buttons. Pressing the volume down button select “Restore original settings” (English “ Factory Reset"). To confirm your choice of action, press the Power key.

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

Menu button on the phone android samsung and many others, maybe sensory, physical and of course, like almost everything, sometimes it doesn’t work.

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

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

However, you can try to calibrate the screen of your smartphone - maybe it will help and there will be no need for repairs by specialists.

What to do if the menu button does not work on your Android smartphone

From the first words I will immediately say that you can fix the problem yourself broken button the menu is not simple.

However, you can live without it, as well as some other “home” and “back” ones, 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 operation.

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

Sometimes the problem can be solved without opening the case - by duplicating the function keys, but this will not work on all Android devices.

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

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

There is a program that does not require root rights, which allows you to duplicate 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 location, only the screen is reduced by the height of the icons.

Reasons for menu buttons not working in Android

The cause may be a software or hardware failure. Fortunately, 90% of problems in software glitch, which is solved independently.

To do this, go to “settings” and click on the section “ backup and reset." There we choose full reset settings with deletion of all data.

Naturally, before doing this, we separately save everything we need (you can do it on your computer and then transfer it back to your phone).

The last option is “reflashing”, which requires skills and contacting a service center.

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

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

• Problems grow gradually, perhaps in a stepwise manner;
• The sensor is equally awkward in all parts of the screen;
• There were no strong shocks, falls into water, extreme temperatures or 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 failure.

How to fix the sensor on your phone at home, having experience?

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

• You disassemble the case, remove the screen and free the sensor if it is not integrated;
• Clean the contacts, press the sensor contact to them, apply power and check the result;
• If you are lucky and everything works, we secure the contacts with a dielectric and perform the assembly;
• If not, we look for the problem further or ask for help.

All safety rules are simple and intuitive, so we won’t focus on them separately, but following them is vitally important.

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

Don't panic, as stated in the pages of the Guide. Everyone started at some point, and as a result, many of them became successful, which means you have a chance. Collect all the data about the device, watch repair videos, find aspects you don’t understand and clarify them. If you feel ready, start. In the end, if you don’t take information that can be sent in advance, you only risk money, and this loss is not irreparable.

The sensor is not such a complex and delicate module that only a select few can easily repair it. When you turn to 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 clear answer as to what is easier: restoring a classic mobile phone, worn out by life, or a modern modular smartphone. One thing is certain - may the one who walks overcome the road!

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

But, unfortunately, failure of touch buttons is not such a rare occurrence, and in terms of reliability they are in no way superior to regular buttons. 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 cleanliness. If you touch the screen with dirty hands, dirt particles stick to the glass and then reduce the sensitivity of the sensor until it fails completely.

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

Inaccurately applied film

Sticker protective film– it’s not an easy matter. There should be no air bubbles left underneath, otherwise some touch buttons will not be able to fully function.

Many phone owners decide to stick the film on themselves, but are subsequently forced to contact service specialists about this, since due to poorly pasted film, the sensitivity of the sensor deteriorates and the buttons do not work.

Temperature imbalance

Failures of touch buttons due to inappropriate temperature are most common in winter, when the thermometer drops below 10-15 degrees below zero. The phone's LCD screen is sensitive to low temperatures and may stop functioning as required if it gets too cold.

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

The touchscreen has moved or is peeling off

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

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

Software glitch

If Touchpad it shines clean, and even the most careful inspection does not show any damage, but the touch buttons still do not work - perhaps the smartphone software has failed. Reboot your operating system by turning your phone off and then on again.

This simple step usually eliminates occasional errors. If this does not happen, remember - perhaps you installed a new application or updated one of the already installed applications before the touch buttons failed. Sensor failure can be caused by a software conflict between old and newly installed utilities. Uninstall the new application and restart your smartphone - it is possible that the touch buttons will restore functionality.

Viral infection

The universal distribution of smartphones has forced hackers who write viruses to pay attention to this segment software. Today, antivirus on a smartphone is the same essential piece of software as on a regular computer.

If you do not have anti-virus 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 all files that seem suspicious.

Reset

If none of the measures listed above work, you just have to try the last remedy available to the average user. Reset your phone to factory settings.

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

Custom firmware

If you have installed so-called custom firmware on your phone, 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 some functions. What’s most offensive is that you don’t even have anyone to file a complaint with. The only way out is to return to the factory firmware, which can be downloaded from the website of your phone manufacturer.
