The control panel on the tablet has disappeared. Managing the navigation bar (virtual keys) on Huawei smartphones and tablets
Icons from the Android desktop can disappear for several reasons and they can be restored - returned to their place.
Icons can fall apart front camera, SMS, phone handsets, menu, call, message, play market, switching camera, gallery, Internet, flashlight, download, YouTube, settings, viber, Skype, Wi-Fi, microphone, title labels, icons, notes, etc. Further.
The most common reason is transferring applications to a memory card. After a reboot they may disappear.
The second reason is accidental deletion. The Android screen is very sensitive, and you might not be able to replace that you accidentally deleted an icon or even an application.
The third reason is spontaneous movement of icons. On an Android phone, you can easily accidentally move an icon from the desktop, for example, to a folder that is created automatically
Other options, which are rare, cannot be excluded. If your reason is not addressed in the post, please let me know through the comments and we will find a solution.

How to get back missing icons from the desktop - the reason is in the flash drive
To get back the Android icons that disappeared due to moving applications to the memory card, you need to transfer them again to the phone's memory.
Note: I am writing based on a Samsung Galaxy smartphone with Android installed 6.0.1 - so your configuration may differ slightly.
If you can transfer the file to the phone’s memory and the icon is back, great; if not, then delete the application and install it again, only this time to the phone’s memory (take out the USB flash drive during installation).
What is described in this section concerns icons third party developers. Of course, this option won’t work with built-in ones. How to restore them - more on that below.
How to restore icons from built-in applications if they disappeared from the desktop
Built-in icons include icons that may disappear: SMS notifications, camera, phone, menu, play market, gallery, Internet, YouTube, settings, notes, etc.
These programs cannot be removed (you can if you modify the firmware - install root rights).
They almost always disappear due to accidental movement or deletion and disappear only from the desktop, but always remain in the menu.
Therefore, if this is your case, go to the menu (usually a white icon with nine black dots) and look for the icon in it.
Then press your finger on the icon, hold it for 2-3 seconds and then you can drag it to the desktop (it will also remain in the menu).
In some devices, the icon seems to stick to your finger, but you cannot lift your finger from the screen, otherwise the procedure will have to be repeated.
In this way you can quickly restore the missing icon - return it to its place as before.
What to do if the icon disappears and you don’t find it in the menu - how to restore it then
Yes, sometimes the icon may not be found. Why? Because if, when moving (even accidentally), the icons do not move apart, then a folder will be created on its own and it will fit there. For example, like in the picture below.
Then open the folder (click on it) and drag it to the desktop using the method described above.
ATTENTION: carefully examine the screen of your smartphone or tablet, otherwise you may not notice the folder.
NOTE: creating such folders great way reduce the number of icons that you rarely use (some have hundreds of them and you can get lost on the screen).
Missing icons - an interesting way to quickly restore
You can return missing icons in another way - using launcher applications.
There are a lot of launchers developed, but most of them are made in a hurry - that’s why they are buggy.
I recommend "Hola Launcher" (no crashes were noticed during experiments). After installation appearance The screen will be converted (the built-in one will be replaced with a new one).
Moreover, if the icon disappears and is not in the list, you can create a new one. That's all. If you have any comments or solutions, drop them in the comments and we’ll fix them! Let's decide! Good luck!
On some Huawei smartphones, in particular Ascend D2, Mate, P6, and tablet Huawei Mediapad 10 FHD familiar touch keys were replaced by virtual ones. Given technical solution definitely quite interesting, though significant drawback is to use part of the screen for this very virtual panel navigation. Huawei engineers found a solution to this problem and implemented the ability to minimize virtual keys (Back, Home and Menu) in firmware on Android based 4.1.2.
For your information, Google implemented this feature only in Android 4.4 KitKat, and Huawei banned its use in their firmware six months ago.
But thanks to the fact that this opportunity has already been implemented in the firmware, it can be activated quite easily.
Method one:
To activate minimizing the panel in this way, you must have root rights on your smartphone and install file manager, capable of working with system folders, For example, Root Explorer.
- Go to the /system/ folder Root help Explorer.
- Find and open file build.prop using the editor.
- Find string ro.config.hw_shownavisettings=false and change the value false on true .
- Save changes to file.
- Reboot your smartphone.
- Go to Settings->Navigation Bar->Collapse Navigation Bar and enable the ability to control the panel.
Method two:
This method is suitable for those who do not have the ability or desire to root their device. From necessary software You only need SQLite Database Editor.
- With help standard application AllBackup do 2 backups System Settings systems with disabled encryption.
- Open using ES Explorer/Root Explorer/Huawei File Manager, or any other file manager, folder
/HuaweiBackup/backupFiles/YYYY-MM-DD_HH-MM-SS/ on the memory card, where YYYY-MM-DD_HH-MM-SS corresponds to the date and time the backup was created. - Open file system setting.db with help SQLite Database Editor.
- In the table system find the hide_virtual_key variable and change its value from 0 on 1 .
- Go to the AllBackup utility and restore data from the SD card from the edited backup.
- Reboot your smartphone.
When resetting the settings to factory settings, or after updating the firmware, these manipulations will have to be performed again.
Enough simple program for entering and switching languages to tablet computer greatly facilitates the user’s process of working, communicating over the Internet, as well as playing and surfing the Internet. However, during use on-screen keyboard problems may arise. And in this case, device owners are trying to understand why the keyboard on the tablet does not work. This question is answered and explained by industry gurus.
The on-screen keyboard on the tablet does not work: possible reasons
Among the most common problems Incorrect or complete failure of the on-screen keyboard is:
- Incorrect operation of the program.
- Software failure.
Both options require a special approach to solving the problem.
Incorrect operation of the language application
It may be that the on-screen keyboard does not appear at all or does not respond to user commands. To solve the problem, you should:
- Open settings and find the language application.
- Click the “Clear data” button, stop the program and clear the cache.
- Restart the tablet.
After such actions, in most cases the program performs its functions, restores normal work. If this does not happen, you need to look for other ways to solve the language problem.
Software failure
It can occur after installing a new application that conflicts with the software. Sometimes malicious adjustments to the program are made by viruses that can be “picked up” on the network. To get rid of them, you need to install antivirus program on mobile device and delete malware. And to solve the problem with the electronic (on-screen) keyboard, you need:
- Go to tablet settings.
- Open the “Language” tab.
- Click "Input Methods".
- Make sure it's the opposite required keyboard there is a check mark (it must be active).
All these actions should help solve the problem. If this does not happen, you will have to reinstall language program. There are quite a few of them on the Internet, including modern intellectual ones (with voice dialing, the ability to write letters on the tablet screen) and the simplest.
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 requests to service centers contains 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 a sudden inoperability physical buttons"back, home and menu." 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 applications that receive required access for you, no longer need to read multi-page instructions. Just install the program Kingo Root to 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 in system directory not visible, no problem. IN top corner programs have an ellipsis - 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. 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.
