How to remove applications from Android. Important and useless stock apps

Manufacturers of Android smartphones usually install many different applications, which are then not used by the user and consume system resources. However, such applications are considered standard and cannot be removed by ordinary means. This situation often does not suit users and they wonder how to remove standard applications on Android.

In this article we will try to answer this question. But before we get started, there are a few important points to note. Firstly, deleting standard applications can lead to unstable operation of the device. In order to reduce the likelihood of various problems and errors, do not delete applications with an Android or Play Market icon. And secondly, to remove standard applications you need ROOT rights. Without ROOT rights nothing will work, don’t even try.

Method number 1. Use the Root Uninstaller application.

The easiest way to remove standard applications on Android is the Root Uninstaller application. This application allows a user who has ROOT rights to manage standard applications as he wants. For example, with Root Uninstaller, you can uninstall stock apps, freeze stock apps, create backups of uninstalled apps, restore deleted apps, and hide apps.

The first thing you need to do is configure ES Explorer to work with ROOT rights. To do this, launch ES Explorer and swipe right to open the side menu of the application. Once the menu is open, go to the Tools section. Here you need to click on the “Root Explorer” menu item and turn it on.

As a result, a request to grant root rights will appear. Click “Ok” to grant root rights to the application. And after root rights are granted, click on the “Root Explorer” menu item again and do not release your finger until a menu with additional settings appears on the screen. In this window you need to select “Connect as R/W”.

And then, check the boxes next to the “RW” option and click on the “Ok” button.

This completes the setup of ES Explorer and you can proceed directly to removing unnecessary standard applications on your Android device. To do this, use ES Explorer to open the internal memory of your Android device and go to the folder /system/app. Here you just need to mark the APK files of standard applications and click on the “Delete” button. In addition to APK files, you also need to delete files with the application name and ODEX extension (if any).

If your device is running Android 5.0 or a newer version of Android, then in the folder /system/app all applications will be in separate folders. In this case, you need to delete them along with these folders.

After deleting the applications themselves, you need to remove updates for them. To do this, go to the folder /data/app and if there are APK files with updates, then they also need to be deleted.

In Android 5.0 and newer versions of Android, updates will also be located in separate folders. As before, we simply delete them along with the folders.

The last step in removing standard applications is to delete the databases and cache that are associated with the application. To do this, open the folder /data/data and delete the folders there associated with the standard applications you want to remove.

That's it, the removal of standard applications from Android is complete. Reboot your device for the changes to take effect.

Manufacturers of smartphones and tablets - Samsung, Sony Xperia, etc. – installed and continue to install many unnecessary applications in their versions of Android 6.0, 5, 4.4, 4.4 2, and even 2.3 6 directly at the manufacturer’s factory - they are integrated into the system as standard.

Often these pre-installed applications are superfluous, and their presence in the system would not be superfluous if they did not work in the background, that is, they did not use part of the RAM, which affects the efficiency of the device.

Removing such “junk” applications requires access to the root of the system - superuser rights, then you will have access to all necessary directories and files.

Only Android by default uses an account with fewer capabilities, as a result, system damage is highly unlikely.

An ordinary user can delete independently installed files, but those that belong to the system - system ones - cannot be done in the usual way on any of the existing versions of Android: 7.0 Nougat, 6.0 Marshmallow, 5.1 Lollipop, 5.0 Lollipop, 4.4W KitKat, 4.4, 4.3 Jelly Bean , 4.2, 4.2.1, 4.2.2, 4.1, 4.0, 4.0.3, 4.0.4 Ice Cream Sandwich, 3.2 Honeycomb, 3.1, 3.0, 2.3, 2.3.3, 2.3.4 Gingerbread, 2.2 Froyo, 2.1 Eclair, 2.0.1, 2.0, 1.6 Donut, 1.5 Cupcake, 1.1 Banana Bread, 1.0 Apple Pie.

In general, buying a smartphone or tablet is almost no different from buying a new computer - you need to clear the system of standard applications pre-installed by the vendor, the usefulness of which is questionable.

The standard way to remove installed applications on an Android tablet or smartphone

For this tutorial I used a Samsung Galaxy smartphone running Android 6.0 OS, but the procedure in others, for example 5.1, is similar in all respects, so you should not have problems.

The easiest way to remove an app from your Android smartphone or tablet is through the settings, so let's get started.

After gaining superuser rights, you can easily completely remove preinstalled files.

Everything written above has one drawback - root rights are very easy to obtain on Android up to version 4.4, and those above are more difficult and even more dangerous, but there is a way out - you can remove Google applications through a computer without root rights.

How to disable the google application even all at once via a computer

If the files you downloaded are easily deleted in any version, then working Google root files will undoubtedly cause difficulties, especially in version 5.0 and higher.

Then download the Debloater program and enable USB debugging on your smartphone or tablet - who doesn’t know, .

You can disable everything at once - check the boxes next to unnecessary ones. Immediately after this, the “Apply” option will appear on the top left side and if you click on it, the selected files will begin to disappear.

That's all, now you know how to remove / disable applications, including Google system ones on all versions of Android.

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.

Which built-in (system) Android applications can be removed. There are built-in applications that we do not use, and these applications and services only take up space and eat up RAM; they can be deleted.
In order to remove some of them, we will need Root and need to install the Root Browser program or . Next you should follow the path" / system/app/ ", here are those built-in applications that cannot be deleted. Sometimes this folder needs to be remounted for reading and writing since it can be read-only. To do this, for example, in RootExplorer, press the button labeled “ Mount R/W", if it says " Mount R/O"then you don’t need to click it, the folder is already writable.

We note what we need to delete and, just in case, transfer these files to a pre-prepared folder on the SD card. We transfer, and do not delete, so that everything can be returned back, otherwise you never know. We reboot the device and they are gone. And yet, this folder also contains system applications necessary for the functioning of Android; when they are deleted, the tablet or phone may not boot, so we delete only what we know for sure. When deleting an application or service, you should also delete its NameProgram.odex, if the firmware is deodexed, if deodexed, then these files will not exist.

Removing Android system applications using SystemApp Remover

FAQ on removing built-in applications

1. Q: Where are the stock programs and how to remove them?
A: Stock (standard or factory) programs are located in / system/app.
You can open this directory using , Root Browser and similar ones, as well as Titanium Backup if you have ROOT rights and mount it in r/w. The order and names may differ (Titanium Backup displays program names instead of .apk files). Remember that it is not necessary to immediately delete the application; you can rename it or freeze it using the Titanium Backup program. In this case, the phone will not recognize the renamed file as an application, and you will be able to restore/unfreeze it if necessary.

2. Q: What programs can be removed?
A: Each user must decide for himself which system applications he does not need, then you need to see whether there may be consequences from deleting applications you do not need, if there are no consequences, then you can safely delete these applications. And if there are consequences, for example, some programs have dependencies, then you need to think about deleting them or not, for example, you don’t need Google maps and you will never use system and third-party programs that use Google maps data, then you can safely delete these maps .

3. Q: Where are the files left from deleted applications and do they need to be deleted?
A: Parts of programs may remain in data/data, data/dalvik-cache, (system/lib- it is advisable not to touch, because there are dependencies). File names do not always match the application name. Be careful. To find out the “internal” name of the program, you need to go to the folder where it is located with the program, then short tap on the apk file - click view and look at the manifest. After removal, it is advisable to do a Hard reset. If you do not plan to do a Hard reset after removing system programs, then you need to remove the “tails” from the specified partitions of the system, but I would not recommend doing this method of removal, it is difficult and you need to delve into the name of the programs. In the above sections, programs are usually called differently than in system/app, it is better to make it simpler, remove everything unnecessary from system/app and then do Hard reset. And that's all, after Hard reset if the program is not in system/app, she obviously won’t put her data in the section data. But unfortunately such simple cleaning will not affect system/lib. The "tails" will remain in this section. However, many people, even with the complex removal method indicated in the mini-fact, do not bother system/lib. Since this is a really dangerous folder, it is correctly written there that it is advisable not to touch it, lib There are almost none with an explicit name that can be deleted. Explicit name and association with remote programs from system/app, have only two, these are keyboard libraries.
Let me explain the “danger” of the folder system/lib, after removing some lib.so, if you reboot the phone or do a Hard reset, the system (android) will not boot. On the phone screen you will see a cyclic reboot (constant reboot). You can get out of this reboot either by re-flashing the phone, or through recovery mode using update.zip. This archive should contain a remote library and scripts with commands on where to place this library. That's the whole danger of the folder system/lib

4. Q: Is it possible to delete standard Google applications; will this affect the operation of the device?
A: Applications (Maps, Gmail, Gtalk, etc.) are possible. Services are undesirable, since if deleted, all Google services and applications will stop working, and permanent errors may appear on the device.

5. Q: Is it possible to remove standard Google applications (Navigation, Addresses, Street View) separately from the Maps application?
A: Street View (Street.apk) is possible, but the others are not, since they are part of the Maps application (Maps.apk).

6. Q: Is it necessary to delete the .odex files of the program along with the .apk files?
A: Yes. These files are part of the application of the same name.

7. Q: Where can I get the standard .apk file from any firmware?
A: Unpack the native firmware and pull out the necessary file.

8. Q: I removed the standard keyboard, after which SWYPE does not work. What to do?
A: Make SWYPE system. Video instructions for installing Russian Swype:

9. Q: I installed a third-party dialer and when a call is missed, 2 notifications appear in the notification panel: from the standard one and from the third-party one.
A: Solution: make a third-party dialer a system one (I did this through Titanium Backup, but I suspect that it’s easy enough to transfer the apk to the system folder).

10. Q: I can’t delete some Google applications; deleted from folder system/app, but they still work.
A: Perhaps these applications are located in the folder data/app and you need to remove them from there as well.

11. Q: How to restore system applications?
A: If you decide to restore a system program that you previously deleted (without backing it up), first find the necessary .apk(if necessary .odex) files (preferably from the firmware version installed on the device). Download the firmware, unzip it and extract the necessary files from the file system.rfs(in some firmware it may be called factoryfs.img and have a different extension). Through (or another file manager with root access) drop these files into the folder system/app and set permissions rw-r--r--;

How to change permissions:
1. Long tap on the apk of the application;
2. Click Permissions

Reboot the device. Once downloaded, this application should appear. Note: To install some applications (for example, Google Play Market), you need to upload the apk and change permissions not only in system/app, but also in data/app.

12. Q: Is it possible to remove the stock launcher?
A: It is possible, but only if you have a stable third-party launcher, which it is advisable to make a system application. But please note that not all standard widgets can work on a third-party launcher.

13. Q: After deleting applications, gray shortcuts of deleted applications remain in the menu. How to remove them?
A: You should clear the launcher data through Settings ( Settings - Applications - Launcher - Clear data) or via Titanium Backup. Please note that as a result of this, all user desktop settings (widgets, etc.) will be lost.

14. Q: How to remove standard lockscreen?
A: Removing it is very problematic (to do this you need to edit several system apk), but you can disable it through Settings - Lock Screen. Or via ShutdownApp (service code *#7594# ; Please note that in this case the reboot menu will also disappear).

15. Q: How can I see running background processes?
A: Enable CPU Usage Data Layer ( Settings- Developer Options- Display CPU usage).

Why did your mobile phone suddenly begin to behave differently than usual, or even take on a “life” of its own? Perhaps because a malicious program has settled in it. Today, the number of viruses and Trojans for Android is growing exponentially. Why? Yes, because the cunning virus writers know that smartphones and tablets are increasingly being used by our fellow citizens as electronic wallets, and they are doing everything to transfer funds from the owners’ accounts into their pockets. Let's talk about how to understand that your mobile device has caught an infection, how to remove a virus from Android and protect yourself from repeated infections.

Symptoms of a virus infection on an Android device

• The gadget turns on longer than usual, slows down, or suddenly reboots.
• Your SMS and phone call history contains outgoing messages and calls that you did not make.
• Money is automatically debited from your phone account.
• Ads that are not associated with any application or site are displayed on your desktop or browser.
• The programs are installed by themselves, Wi-Fi, Bluetooth or the camera are turned on.
• I lost access to electronic wallets, mobile banking, or for unknown reasons the amount in my accounts decreased.
• Someone has taken over your account on social networks or instant messengers (if used on a mobile device).
• The gadget is locked, and a message is displayed on the screen that you have violated something and must pay a fine or simply transfer money to someone to unlock it.
• Applications suddenly stopped launching, access to folders and files was lost, and some device functions were blocked (for example, buttons could not be pressed).
• When launching programs, messages like “an error occurred in the com.android.systemUI application” pop up.
• Unknown icons appeared in the application list, and unknown processes appeared in the task manager.
• The antivirus program informs you when malicious objects are detected.
• The antivirus program has spontaneously deleted itself from the device or does not start.
• The battery of your phone or tablet began to discharge faster than usual.

Not all of these symptoms are 100% indicative of a virus, but each is a reason to immediately scan your device for infection.

The easiest way to remove a mobile virus

If the gadget remains operational, the easiest way to remove the virus is to use the antivirus installed on Android. Run a full scan of the phone’s flash memory, and if a malicious object is detected, select the “Delete” option, saving the neutralized copy in quarantine (in case the antivirus detected something safe and mistook it for a virus).

Unfortunately, this method helps in about 30-40% of cases, since most malicious objects actively resist being removed. But there is control over them too. Next we will look at options when:

• the antivirus does not start, does not detect or does not remove the source of the problem;
• the malware is restored after removal;
• The device (or its individual functions) is blocked.

Removing malware in safe mode

If you can't clean your phone or tablet normally, try doing it safely. The majority of malicious programs (not just mobile ones) do not show any activity in safe mode and do not prevent destruction.

To boot your device into Safe Mode, press the On/Off button, place your finger on “Power Off” and hold it until the “Enter Safe Mode” message appears. After that, click OK.

If you have an old version of Android - 4.0 and lower, turn off the gadget in the usual way and turn it on again. When the Android logo appears on the screen, press the Volume Up and Volume Down keys simultaneously. Hold them down until the device boots up completely.

While in safe mode, scan your device with an antivirus. If there is no antivirus or it does not start for some reason, install (or reinstall) it from Google Play.

This method successfully removes advertising viruses such as Android.Gmobi 1 and Android.Gmobi.3 (according to Dr. Web classification), which download various programs to the phone (in order to increase the rating), and also display banners and advertisements on the desktop.

If you have superuser rights (root) and you know exactly what caused the problem, launch a file manager (for example, Root explorer), follow the path where this file is located and delete it. Most often, mobile viruses and Trojans place their bodies (executable files with the .apk extension) in the system/app directory.

To switch to normal mode, simply restart your device.

Removing mobile viruses via computer

Removing viruses on a phone via a computer helps when a mobile antivirus cannot cope with its task even in safe mode or the device’s functions are partially blocked.

There are also two ways to remove a virus from a tablet and phone using a computer:

• using an antivirus installed on a PC;
• manually through a file manager for Android gadgets, for example, Android Commander.

Using antivirus on your computer

To scan your mobile device files with an antivirus installed on your computer, connect your phone or tablet to your PC with a USB cable, selecting the “As a USB drive” method.

Then turn on USB.

After this, 2 additional “disks” will appear in the “Computer” folder on the PC - the internal memory of the phone and the SD card. To start scanning, open the context menu of each disk and click “Scan for viruses”.

Removing malware using Android Commander

Android Commander is a program for exchanging files between an Android mobile gadget and a PC. When launched on a computer, it provides the owner with access to the memory of a tablet or phone, allowing you to copy, move and delete any data.

For full access to all the contents of the Android gadget, you must first obtain root rights and enable USB debugging. The latter is activated through the service application “Settings” - “System” - “Developer Options”.

Next, connect the gadget to your PC as a USB drive and run Android Commander with administrator rights. In it, unlike Windows Explorer, protected system files and directories of the Android OS are displayed - just like, for example, in Root Explorer - a file manager for root users.

The right half of the Android Commander window shows the directories of the mobile device. Find the executable file of the application (with the .apk extension) that is causing the problem and delete it. Alternatively, copy suspicious folders from your phone to your computer and scan each of them with an antivirus.

What to do if the virus is not removed

If the above operations did not lead to anything, the malicious program still makes itself felt, and also if the operating system ceases to function normally after cleaning, you will have to resort to one of the radical measures:

• reset with restoration of factory settings through the system menu;
• hard reset via the Recovery menu;
• reflashing the device.

Any of these methods will return the device to the same state as after purchase - there will be no user programs, personal settings, files or other information (data about SMS, calls, etc.) left on it. Your Google account will also be deleted. Therefore, if possible, transfer the phone book to the SIM card and copy paid applications and other valuable objects to external media. It is advisable to do this manually - without using special programs, so as not to accidentally copy the virus. After this, begin the “treatment”.

Restoring factory settings through the system menu

This option is the simplest. It can be used when the functions of the operating system and the device itself are not blocked.

Go to the Settings application, open the Personal - Backup section and select Factory reset.

Hard reset via Recovery menu

A “hard” reset will help deal with the malware if it is not removed by any of the above methods or has blocked login. To our joy, access to the Recovery menu (system recovery) is retained.

Logging into Recovery works differently on different phones and tablets. On some, for this you need to hold down the “Volume +” key when turning on, on others - “Volume -”, on others - press a special recessed button, etc. The exact information is contained in the instructions for the device.

In the Recovery menu, select the option “wipe data/factory reset” or simply “factory reset”.

Flashing

Flashing is essentially reinstalling the Android OS, the same extreme measure as reinstalling Windows on a computer. It is resorted to in exceptional cases, for example, when a certain Chinese virus is embedded directly in the firmware and has been living on the device since its “birth.” One such malware is the spyware android spy 128 origin.

To flash a phone or tablet, you will need root rights, a distribution kit (the firmware itself), an installation program, a computer with a USB cable or an SD card. Remember that each gadget model has its own individual firmware versions. Installation instructions are usually included with them.

How to avoid virus infection of Android devices

• Install mobile applications only from trusted sources, refuse hacked programs.
• Update your device as system updates are released - in them, developers close vulnerabilities that are exploited by viruses and Trojans.
• Install a mobile antivirus and keep it always on.
• If your gadget serves as your wallet, do not allow other people to use it to access the Internet or open unverified files on it.
