After a few minutes of refreshing my smartphone, I saw a new application called Duo. Of course, I wondered what it was? But it turns out the search giant has released a new update. After a brief acquaintance with the application, I could not help but write this article.

Step one - registration

So what is the Duo app? I found out that this is a program from Google for making video calls around the world via Wi-Fi or mobile Internet, without taking into account the tariffs of your mobile operator. The first step after launching the application will be a short registration. It looks like this: your phone will receive an SMS with an activation code, which must be entered in the dedicated field using the virtual keyboard (registration ends here).

Step two - settings:

Once launched, Google Duo will promptly ask for permission to access contacts, SMS, microphone and camera. The program will launch and configure itself automatically. But it is possible to manually edit your personal profile. To do this, you need to click the three dots (a somewhat strange menu appearance) in the upper right corner of the screen.

For those who want to know more:

A menu will appear with two items: the first is settings; the second is help and reviews. Select the first item, after which we go directly to the settings. In it you can turn on or off the vibration signal during a call, Knock Knock (thanks to this function you can immediately see who is calling, but this is only possible if the person who is calling is in the recipient’s contact list), limiting the use of mobile data, number phone, unregister a phone number (deleting an account), blocked numbers.

Step three - help and reviews:

Here you can find all the necessary information to work with the application and configure it. Google has also collected articles related to solving the problem of confirming a phone number, synchronizing contacts, sound or video.

Step four - video call:

All contacts will be synced automatically from your account. In order to start a video call, you need to click on the large round button at the bottom of the screen, select a number and the program will begin the video connection. During communication, there is a function to mute the microphone and change the front camera to the main one.

If the person you are about to call has Google Duo installed, then it will be displayed with a blue icon or photo that was set for this phone number. Accordingly, if the subscriber does not have this program, then the icon opposite him is transparent, and on the right side of the contact it says - invite. You can send an invitation to the desired subscriber in the form of an SMS with a link to this application.

Pros of Google Duo - easy to use, very fast registration, good help on using the program in the help menu and reviews (a large number of articles on solving various problems). The application weighs 7.42 MB, good video quality, and the ability to change the front camera to the main one. True, the program cannot send files and this is perhaps its only drawback. If you have any theories regarding Google Duo, please share them in the comments.

Android comes pre-installed with a lot of different apps that you may not need at all - they just take up space and use up the device's RAM. Any of them can be removed, and how to do this is described in this manual.

First of all, you need to get root rights on your smartphone or tablet. They make it possible not only to remove standard applications, but also to easily launch specialized applications that significantly expand the capabilities of the device.

For each device, the method for obtaining Superuser rights varies, but the most universal utilities are: and also.

Then you need to install a file manager that supports access to system directories and editing system files. For example, ES Explorer, File Manager from Cheetah Mobile or . In this tutorial I will use ES Explorer.

How to remove default applications in Android. Method 1

1. First, you need to grant editing rights to the root directory to the file manager. How to do this for ES Explorer is described in.

2. In the internal memory, go to the folder "/system/app".

3. Select the .apk file of the desired application and click “Delete” in the context menu that appears.

4. In addition, you need to delete the .odex file with the same name, if it exists.

In Android 5.0 and higher along the way "/system/app" All built-in system applications are located in separate folders, so you need to select them and erase them.

5. Many system applications in the folder "/data/app" updates are stored, from where they will also have to be deleted.

Again in Android 5.0, updates to pre-installed applications are on the way "/data/app" in separate folders. Select unnecessary ones and delete them.

6. Now all that remains is to erase the caches and databases of built-in system applications and services that are located in the folder "/data/data".

Uninstall pre-installed apps like Gmail, Google Drive or Maps. It is better not to touch system applications with the Android icon (for example, CertInstaller.apk or PackageInstaller.apk), since problems with the system may arise.

Uninstalling Android system applications using Root Uninstaller

Standard applications on Android can be uninstalled using the Root Uninstaller application. Download the .apk from our website and install.

1. After installation, open it and grant Superuser access.

2. Select the application you want to get rid of.

3. Click "Delete". Before deleting, you can make a backup.

In addition, applications can not be deleted, but frozen. This will stop them working and disappear from the menu, but will not be completely removed.

How to remove standard applications through ES Explorer

Some file managers have a special option for working with program files. Let's look at this function using ES Explorer as an example:

1. In the sidebar, under Libraries, select APPs.

2. At the top, click on “Custom”, thereby expanding the hidden menu. Select the “System” item in it.

3. Select programs that are no longer needed. From the list of options, select Uninstall.

I think that the methods I have proposed will be enough to remove standard Android applications. Yes, there are analogues of Root Uninstaller and other file managers that have the function of quickly removing built-in applications. But the 3 methods I talked about are the most convenient.

Today, one of the most common and popular types of smartphones and tablets among users are portable devices running Android OS. In general, this operating system is quite easy to use and provides the user with a huge number of opportunities to work with a wide variety of programs and games.

But not all owners of such devices know how to remove applications on Android that have lost their relevance and are no longer needed. At the same time, there is nothing complicated in such a procedure - it does not take much more time than installing the same program or game.

Uninstalling regular apps

In this case, regular applications mean those programs and games that the user himself installed. In addition to them, there are also standard applications that are already included in the “basic package” when purchasing a device - they are downloaded to a smartphone or tablet either by the manufacturer itself or by the distributor. Such system applications will be discussed below, but for now let’s figure out how to delete what the user himself has saved to the device’s memory.

Among the many options, there are three simple and popular methods by which you can remove an unnecessary game or program.

Method one. Simple

1. You need to go to the device settings.
2. Then you should select the "Applications" tab.
3. From the list that appears, you need to find the program or game that you want to remove.
4. Click on it and select the appropriate item in the submenu that appears.

After this, the unnecessary program will be erased from the Android device’s memory along with all its additional files. But not all applications can be gotten rid of so easily. If this option does not help, you can try the following steps.

Method two. Fast

1. First, you need to find the desired program or game in the “Applications and Widgets” section. Usually the link to the table with this section is hidden in the upper right corner of the screen.
2. Then we look for the unnecessary application.
3. Click on its icon and hold your finger on it for a while.
4. After a basket and the word “Delete” appear instead of the table, simply drag the icon into this same basket.
5. Now it is enough to confirm the selected action and enjoy the operation of the device without annoying (or simply unnecessary) programs.

It’s also worth adding that after holding your finger on the icon, you can not only delete the application, but also pull its shortcut onto the active screen. This will make it easier to access useful programs and the most frequently launched games - they can be activated with one touch.

Method three. "Control"

Sometimes it happens that when using one of the first two methods described above, the application on Android does not want to be deleted. In this case, you can use one of the special utilities that allow you to completely erase a capricious program or game from the memory of a device running Android OS. The most popular among such programs are:

• AppInstaller is an easy-to-use utility that allows you to install or uninstall applications;
• Uninstaller is special software that helps you get rid of an application that cannot be removed in the usual way.

If desired, you can find other utilities that perform the same functions in the public domain. The advantage of such special applications is that they are able to rid the Android OS in your device of absolutely all add-ons and files that are stored in memory along with the installed (and then uninstalled) program.

Method four. Additional

For users who prefer to install software through the Android Market, there is another way to remove a boring game or program. To do this, just go to the Google Play website (this is what this application store has been called since the spring of 2012) and look at the “My Applications” tab. It stores all previously installed programs, which can either be updated or erased from the device’s memory.

Removing system (standard) applications

Often, the manufacturer downloads a large number of programs and utilities into the memory of a device running Android OS that the user simply does not need. At the same time, they are loaded into memory and use system resources. You can remove such applications in at least two ways:

1. Using a special program, for example, Root Explorer or Root App Delete. Such software will allow the owner of a smartphone or tablet to easily obtain administrator rights and erase system entries (this applies not only to files, but also to other data) from system/app.
2. You can also obtain Superuser rights (or simply root) using other programs, for example, the Framaroot utility. If you already have such rights, you can delete the application manually. To do this, just visit the system folder, select all the files whose names match the name of the program (such files must have the extension apk and/or odex), and then erase them.

Why remove unnecessary applications at all?

Finally, it is worth noting that from time to time it is necessary to get rid of unnecessary games or programs, at a minimum, in order not to clog the memory of your favorite device. Even if you have plenty of space on your memory card, these unused apps continue to use the internal resources of your smartphone or tablet, which can cause it to slow down.

Many experts advise carrying out such application cleanings at least once every few months, depending on how actively you install new software on your tablet or smartphone.

Periodically installing or uninstalling games and applications on mobile devices is a fairly frequent procedure that, in principle, can be performed by any user who is at least somewhat familiar with the operating system itself.

The fact is that a previously installed game may well become boring, and some utility simply becomes irrelevant, taking up precious space in the device’s memory. In addition, the manufacturer often includes standard (or system) applications in the firmware, which, taking up the phone’s internal storage and consuming its resources, turn out to be unnecessary for the specific owner of the Android device.

You can read how to remove standard applications from Android, as well as those that the user installed himself, in our material.

Games that you installed yourself can be removed quite simply and without much effort, in two ways.

How to manually remove apps on Android

• Open the Menu.
• Let's go to " Settings", press the position " Applications».
• From the list that opens, select what we will get rid of.
• Click on the item “ Delete».

Note: if the delete button is inactive, it means that a system program has been selected that cannot be deleted in the standard way.

Removing installed applications via Google Play Store

This method may be more convenient for users downloading programs from the Google Play resource. Your actions:

• Let's launch Google Play Market, click on the icon “ Play Market", located at the top of the screen (image of a bag with an arrow to the right).
• Select the item “ My applications", a list of everything you have installed through Google Play will open.
• Among the list, look for the one to be uninstalled, click on it and press the button “ Delete».

But it’s not so easy to remove pre-installed programs or games, because they are built into the “body” of the system, which can be reached by fairly experienced users. But, nevertheless, it is possible to “demolish” an unnecessary service or software. This operation allows you to free up a significant amount of space, which will make working with your device much more comfortable.

How to remove standard applications on Android (Root)

It was already said above that the previously described methods will not be effective, since they are installed in the Android OS along with the firmware. To remove them, you will need to perform an additional operation - obtaining Superuser rights, or Root. We are talking about a system user with unlimited access rights.

Rooting does not work the same for different Android devices. For example, a Chinese manufacturer initially includes root rights in the factory firmware for most manufactured devices, thereby making it easier for us to work with the device.

But first-tier brands for the most part consider this kind of control over their products unnecessary for ordinary users, so such phones or tablets must be unlocked manually to gain root access, and root rights must be full, otherwise, Yes, with partial rights, uninstallation is impossible.

Each gadget has its own programs that provide Root (Framaroot, Remover, Root Explorer, etc.). In addition, your smartphone must have an installed explorer that provides access to the file system.

So, to start the process of deleting files, we grant root access to Explorer.

Utility 1

• Install and launch Explorer, then swipe to the right to open the menu.
• Click the “Tools” item and select the “Root Explorer” value.
• In the window that appears, we grant Superuser rights to the conductor.
• In the next window, indicate “Connect as R/W”.
• In the pop-up menu, put all the checkboxes to “RW” and confirm the action.

Utility 2

• Select the “Settings” field from the menu.
• Find the item “Root Explorer” and check the box.
• We confirm the request for Superuser, after which we remove unnecessary applications.

If you have received root rights to your smartphone, you should know that system applications are stored in Android memory in the /system/app (or /data/app) folder, access to which is provided by specialized software. This can be any file manager, for example, Root Explorer. If the program refuses to move/delete files, change the settings by pressing the R/W button (the value changes to R/O).

What should not be deleted

Important: Before performing the uninstallation procedure, be sure to think about what you will be deleting! Applications that are unfamiliar or insignificant in your opinion may be responsible for the functioning of important and necessary services. For example, unnecessary programs from Google can be “demolished” without much thought (mail, maps, etc.), but services should not be touched under any circumstances.

If, for example, the Wi-Fi service was accidentally deleted, wireless data transmission may completely disappear. The actual removal looks quite simple: we find the desired folder, delete apk files with the same name as unnecessary programs, making sure to delete files of the same name with the odex extension.

To ensure safety, listen to the advice of experts who recommend not permanently deleting unnecessary files, but “freezing” or moving them to a memory card or another directory in order to be able to return them to their place if necessary.

How to remove built-in applications on Android (without Root)

• Walking the familiar path: “ Menu", then " Settings" And " Applications", we reach the tab " All».
• We select what we need, click the value “ Force stop».

It should be noted that this method will not “freeze” all selected programs.

Conclusion

I would like to believe that our instructions were clear and useful for you, and you can easily remove pre-installed applications that the manufacturer has generously crammed into your Android. Let us remind you once again about the necessary caution so that you do not have to completely change the operating system firmware due to man-made failures. Good luck!

Over time, some applications and games become unnecessary for the owner. To uninstall them correctly, you need to know how to remove a program from your computer without leaving unnecessary files in the registry. The rules are the same for both laptops and desktop PCs. You can uninstall using the tools built into Windows or third-party utilities.

You can not only remove unnecessary programs from your computer, but also work with the registry. Keep in mind that you can only perform these actions if you understand what you are doing. Otherwise, there is a risk of erasing the necessary documents.

Free Uninstall tool

This is a lightweight, simple utility that is distributed freely on the Internet. The Uninstall tool can be used without purchasing a license. During installation, in addition to the main folder, hidden ones appear in other places on the PC, and registry entries are added.

What to do if the program is not uninstalled

Sometimes users may encounter a situation where a file or folder that cannot be deleted appears on their PC. In this case, you will need special applications that remove the ban. Utilities for unlocking files LockHunter or Unlocker are considered popular. These options help you remove the lock from the desired element, which gives you the message “The file cannot be deleted.” Instructions on how to remove an uninstallable program:

2. Right-click on the document that voluntarily does not want to go into the trash.
3. In the window that appears, click on “Delete” and click “Ok”.

LockHunter works on the same principle. When you install it, when you right-click on any document, there will be a new line in the menu “What is locking this file?”. When you activate the item, a note will appear in which the path to the document and the processes that prevent it from being erased will be written. To get rid of a document, you just need to click on the “Delete it!” option.

How to remove a program from a remote computer

Sometimes it’s easier to do everything yourself than to explain to a person who doesn’t understand the issue. You can uninstall programs on a remote computer. Only users who have experience handling computers on a local network will be able to do this. Use of another PC must be approved by the owner. To work you will need the built-in WMI utility, you need to do the following:

1. Press Win+R keyboard shortcut, write cmd.exe to launch the command line.

Removing portable programs is completely done with a simple key combination Shift+Delete. If you want to send the folder to the trash, then simply Delete will suffice (this will leave you the opportunity to restore the data if necessary). Such cases do not require additional cleaning of the registry.

What programs cannot be removed from your computer

The main thing in this process is not to get carried away, because you can erase something truly important. There is a list of folders that should not be affected by the complete removal of programs. Some data is responsible for the operation of the entire operating system and overwriting it will lead to the computer not working. You cannot delete anything from the following folders:

• ProgramData – if you don’t know what the folder is responsible for, then you shouldn’t erase anything from it;
• Windows is the main folder of the OS, all components of the system are located here;
• Program Files – installed software, only if you understand what the folder is responsible for can it be erased;
• Users – user data;
• Boot – system boot files.
