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.

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.

The notification panel on Android is one of the main interface elements operating system. With its help, users gain access to key device settings and important notifications, and additional applications allow you to expand the functionality of the notification panel and make working with your smartphone more comfortable. In this article, we will tell you how to customize the notification panel and what to do if the notification panel is not working.

How to customize the notification panel on Android

On smartphones different manufacturers The notification panel on Android may be visually different due to the features of the installed shell, but still the main elements have approximately the same arrangement. The panel opens by swiping down from the top of the screen; by swiping backwards from the bottom, the control panel can be removed.

At the top there are switches for quick on/off wireless networks, mobile transmission data, sound settings, screen brightness, and so on. At the bottom of the panel, you can see current notifications from applications. Each notification can be opened with a tap or hidden with a swipe to the side.

To customize the notification bar, go to your device settings and go to the Notifications and status bar section. Here you can select the location of the switches and appearance notification panel elements.

Using the Notification Toggle utility, you can expand the functionality of the notification panel - add switches and shortcuts for quick access To installed applications. Find the switch you are interested in in the application and check one of the boxes next to it.

Application shortcuts are added like this:

  1. Open Notification Toggle
  2. Swipe to the tab on the right
  3. Click "Add Application"
  4. Select the applications you need

What to do if the notification panel is not working

First, you need to figure out why the notification panel does not open. There may be several reasons:

  • Software conflict with a third-party application
  • Firmware update fails
  • Device screen sensor malfunction

If the notification panel stops opening after installing an application, try uninstalling it and checking the functionality of the notification panel again. If the notification bar error appears after updating the firmware, do the following:

  1. Try installing the update again
  2. Do a factory reset (read the article)
  3. Reinstall the firmware (read the article)

Often problems with the notification panel occur due to a malfunction touch screen devices after falls or moisture (read our article). First you need to check the operation of the screen sensor using the Screen Touch Test utility. Open the app and tap on different areas of the screen. Where the clicks are registered and a white mark remains, the sensor is working properly.

If there is no white mark left in the upper area of ​​the screen, it means that the sensor in these places does not respond to presses, which leads to the inability to open the notification panel. The best solution in such a situation would be to contact a service center, however, you can also use alternative ways open the notification panel.

Other ways to open the notification panel on Android

If the notification panel does not open due to a problem with the sensor at the top of the screen, third-party applications can help you.

With Status Bar Shake Opener, you can open the notification bar with gestures by tilting your device to the left. Select in the application the force of response to the rotation of the device that will be convenient for you. This way you can open the notification panel without using the touch screen.

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, 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) program Root 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.

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 collapsing the panel in this way, you must have received root rights and installed file manager, capable of working with system folders, for example, Root Explorer.

  1. Go to the /system/ folder Root help Explorer.
  2. Find and open file build.prop using the editor.
  3. Find string ro.config.hw_shownavisettings=false and change the value false on true .
  4. Save changes to file.
  5. Reboot your smartphone.
  6. 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.

  1. With help standard application AllBackup do 2 backups System Settings systems with disabled encryption.
  2. 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.
  3. Open file system setting.db with help SQLite Database Editor.
  4. In the table system find the hide_virtual_key variable and change its value from 0 on 1 .
  5. Go to the AllBackup utility and restore data from the SD card from the edited backup.
  6. Reboot your smartphone.

When resetting the settings to factory settings, or after updating the firmware, these manipulations will have to be performed again.

Young smartphone users on the Android OS often have the question posed in the title of the article. " Here was the iconPI remember where it stood, used it, and suddenly it was gone. I can’t call/View or send SMS/Take a photo/Go online/etc.Who is to blame and what to do?»

Let's look at a few typical cases.

1. You accidentally deleted either an icon or an application.

If you click on the application icon and hold your finger on it for a while (about 1 second), it will “ sticks to your finger, and at the top of the screen will appear shopping cart icon. If you move an icon to the trash bin, it will turn red and when you release your finger, both icons will disappear. As a result, the original the icon will be removed. Unlike Windows, here the Recycle Bin folder does not exist in files and it is impossible to restore an icon deleted to it.

However recovering a deleted icon perhaps from . This menu is called up by clicking on the button with the image Lattices and contains icons of all installed system and custom applications.

If found in the list the right application and hold your finger on its icon, then some versions Android OS it will also stick to your finger, and under them an image of the last desktop will appear, on which you can release the icon and it will thus be restored to it. At the same time, she will remain on her own same place in the Application Menu.

IN other versions OS, when you hold your finger in the Application Menu, crosses appear on the icons, and images of all desktops appear at the bottom of the screen in a reduced scale, where you need them drag icon to restore.

Be careful with crosses! They are intended for removing no longer icons, but themselves custom applications. In this case, to restore them, you will need to re-download and install the application from Google market Play.

So if you can't see your missing icon even in the Application Menu, then there is two options:

  • either you deleted the application, as I just described;
  • or you accidentally or deliberately disabled it without completely deleting it.

In the latter case look for it among the disabled ones and include ( Settings - Application Manager - Disabled tab (swipe from right to left) - Looking for an application - Enable - Reboot the smartphone).

2. You accidentally moved the icon.

You probably noticed that an icon stuck to your finger can be removed without releasing your finger. move around the screen, changing its position and moving other icons apart. When moving off screen it ends up on the next desktop. This case is typical when you accidentally held your finger on the icon longer than necessary and did not notice how it stuck and moved to the next table. So try looking for the “missing” icon on nearby desktops.

The second case of movement is creating a Folder. If you place a sticky icon not between other icons (in this case it spreads them), but directly on top of another icon and in this position release, then both icons are placed in a newly created folder with the name (which can be changed by tapping on it). You may also, due to inexperience, not notice that created a folder and “lost” its icon in it. Look for folders, enter them and pull your icon back out, on your desktop and in the right place. By the way, folders are very handy tool to save space on your desktop. Use them consciously. See a couple of folders in the first screenshot.
