How to change Galaxy S8 onscreen buttons? Service codes and key combinations for Samsung Galaxy smartphones

The “menu” button in the Samsung Android phone and many others can be touch, 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 very first words, I will immediately say that fixing a problem with a non-working menu button on your own is not easy.

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 with function keys appear on the display: 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 are caused by a software glitch, which can be resolved on its own.

To do this, go to “settings” and click on the “backup and reset” section. There we select a complete reset, deleting 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).

You can also use the Turbo Cleaner program. The application is able to control phone functions.

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 you most likely cannot do without a service center. Good luck.

Service tools become useful in cases where the user needs to access certain functions that are not available in normal mode. By and large, they were invented to test the operation of the device, but we can also use them to call up various menus.

Advanced users deal with them all the time. For example, on some Galaxy devices you can adjust the sound volume, find out hidden information about your phone, and much more. Now we will analyze the most useful service codes that are suitable for users of Samsung smartphones and tablets.

How to enter the service code?

Everything is very simple. Open the dialer and enter numbers with signs that correspond to the menu you want to execute. After entering the last character, the menu should automatically launch; no additional actions need to be performed.

Denial of responsibility: This information is intended for experienced users. You should not try to change anything in the settings if you are not familiar with mobile devices. We are not responsible for any subsequent problems, including loss of data or damage to hardware.

I repeat that you should not touch those parameters whose meaning you do not know. You risk losing the functionality of your phone or valuable data.

Control buttons are divided into mechanical and software. The first ones are located on the body of your gadget - these are the power button, the volume rocker (two buttons with one rocker key) and sometimes the Home(lately it is more often software.

The second ones are virtual buttons located on the screen of a smartphone or tablet and also controlled by pressing a finger, but on the screen. This is a soft button Home, button Back and button Latest apps(sometimes this is a context menu button). The appearance of these buttons depends on the version of Android OS used. This can be, respectively, a house, a curved arrow and two rectangles one after another (Android 4.x version) or, respectively, a circle, a triangle and a square (Android 5 version).

Let's dwell on assignment of control buttons.

Purpose of the button nutrition and swings volume obviously. However, the peculiarity is that the inclusion turned off The smartphone is started by long (more than 2 seconds) pressing the power button, followed by the OS loading process. At working smartphone short press this button calls lock screen(if it is enabled in the settings) or directly going to the desktop. When the smartphone is running, long pressing the power button brings up the Menu, which contains items Shutdown,Data Transfer, Offline Mode and Reboot(Restart).

Mechanical button Home when pressed briefly, it calls up the lock screen or goes to the main desktop. Long press may cause list of recently running applications, and double-clicking one of the programs (for example, in Samsung smartphones the S Voice application is called up).

Software button Back causes a transition to previous screen, successive clicks - respectively, on several previous screens until the application is closed. Here it must be emphasized that in the latter case the application is unloaded from RAM, while pressing the button Home causes a transition to the main desktop, but the previously opened application remains in memory and continues work in the background.

Button Latest apps is very convenient, since if you need to relaunch one of the previously used applications, there is no need to look for it again in the general list of programs ( Applications Menu) or look for its icon on desktops. Applications in the list are always arranged in reverse chronological order of their launch (the most recently launched ones are first in the list). In addition, the list window contains additional buttons for calling up the List of active tasks (running in the background of applications), a Search for applications button, and a Clear the list of recent applications button.

Why doesn't the "home" and "return" buttons work?

Typical causes of failure:

• mechanical damage, phone falling;
• liquid getting under the housing;

And Galaxy S8 Plus. These are brand new phones with lots of new features and other changes. For example, there is no longer a physical home button. Luckily, the screen navigation buttons are fully customizable.

After being announced on March 29th, Samsung finally released the new phone on April 21st. Now that the Galaxy S8 is in the hands of millions of users, we're getting a lot of questions.

For the first time in seven years in Galaxy history, the S8 uses virtual keys on the screen. There are no physical Back, Home, or Recent Apps buttons like on previous devices. As a result, owners will have to completely relearn how to interact with a smartphone. It's quite simple, however, because the S8 still works like most other Android phones available today.

Luckily, Samsung includes accessible control customization options. If this is your first Galaxy, the back button is most likely positioned incorrectly for you. All other Android smartphones place it on the left. If you want to change the position of the buttons, here's how to do it.

How to customize Galaxy S8 navigation buttons?

As with other phones, all users can head to the settings menu and find a host of additional controls and options. Samsung allows the owner to switch navigation keys, add a background color and other interesting things.

• Pull down the notification panel and tap the gear-shaped button (or find Settings in apps);
• Click on the “Display” section;
• Scroll down and select "Navigation Bar";

From here, users have several options to choose from. You can change the background color of the on-screen buttons to match the theme of your device. Or choose the color yourself. Additionally, Samsung adds a color wheel for more precise customization.

You can then go to the button layout and choose whether you want a back button on the left like on most Android devices or keep the Samsung style with a back button on the right.

Users can also enable a hard press on the Home button to go to the home screen from anywhere. Be it a locked smartphone, a switched off smartphone or an app/movie in full screen mode. We recommend enabling this option.

Finally, there is a slider that allows owners to adjust the pressure and vibration activity of the virtual keys and the Home button.

As a note, in some situations, the background color of the navigation bar will not be the color you selected. Some apps or even the home screen default to a transparent navigation bar or other colors. Either way, it's nice to see this level of customization on Samsung's latest flagships.
