How to make an application a device administrator. Why are such rights needed?
This can happen to anyone - when you try to delete an application, it turns out that it cannot be deleted. Moreover, in in this case we're talking about not about the built-in application in the firmware, which cannot be removed without root rights, but about the most common one, which you installed on your device.
For example, some time ago we talked about this and also showed an application called Volume Unlock, thanks to which you can turn on the device by pressing the volume up button. When running, the application receives administrator rights, so in a simple way it cannot be deleted. But let’s show you clearly what it looks like.
Go to settings and find the “Applications” section.
Here we see a list of applications. Select the one you need (in our case, Volume Unlock).
And what do we see? That's right, the "Delete" button is inactive.
If you encounter similar problem, no problem, it can be solved. To do this, go to Google Play and type in the search the word “uninstall” (without quotes) or uninstaller. Select an application from Rhythm Software and install it. This is extremely small free application, which does not even require granting additional rights.
After installing the application, open it and see a list of all installed applications. Select the one you need by tapping on it once, and then click on the “Delete selected applications” button, which is located at the top of the screen.
We agree with the deletion and see a window in front of us in which it is written: “It is impossible to delete the package because it is selected for device administration." Click “Administration Settings”.
A window opens and uncheck the application.
In a new window, disable the application’s administrative rights by clicking on the “Disable” button.
After this, we get to the application page and see that the “Delete” button is activated.
Click on it and the application is deleted.
Of course, this way you can remove virus applications that cannot be deleted in the usual way. To remove system applications, you must have root rights.
Second way
For this method we thank the user with the nickname Android, who in the comments suggested less complex method uninstalling such applications. He talked about another method that requires enabling USB debugging. A user with the nickname Valery reported that you can use this method without USB debugging, for which we thank him. And yet we show an example precisely with USB debugging- just in case. We advise you to immediately open the “Security” section (see the last three screenshots) and if this does not help, try enabling USB debugging.
Go to settings. Here, find the “About phone” (or “About tablet”) section.
After opening this section, it will appear in the settings:
Go into it and check the box next to “USB Debugging”.
Here you will see a check mark for an application that cannot be removed in the usual way.
Simply uncheck the box, then click Disable.
The application can now be uninstalled as usual.
Incredibly simple. To do this you need to find the desired program or a game, read the description and reviews of other users, after which you can safely click on the “Install” button. Uninstalling apps is no more difficult: it only takes a few clicks. However, from time to time the system refuses to remove certain programs, not to mention applications pre-installed by the manufacturer. How to get rid of this problem? Let's find out.
In general, there are two reasons for not deleting an application. In the case of the first, the annoying program can act as a device administrator. The second option is much more common, and each of us has probably encountered it. We are talking about applications that are part of the smartphone system. In other words, programs preinstalled by the company’s engineers, for which there is simply no delete key.
Possible solutions for both the problems described above our foreign colleagues from phonearena. Let's look at each of them separately.
Administrator application
Don't rush to close this article: There is nothing wrong with this phrase. The fact is that some applications require more extensive permissions. For example, setting a password on a smartphone, blocking it, tracking geolocation and much, much more.
In this case, to remove them, just uncheck the special section of the menu. In my good old HTC One S, which returned to use after the iPhone, to do this you should go to settings - security - device administrators. One problem is solved, but what about the other?
System Application
Not all smartphone manufacturers love their users. The proof of this statement is great amount absolutely useless pre-installed applications that you have no desire to use. In a Taiwanese smartphone, again, similar ones include the EA Games icon, Friend Stream, Rescue, Teeter and other dubious programs.
Agree, it’s not so much their presence that’s annoying as the inability to get rid of them, right? However, it turns out that there was a way out of this situation.
To do this, you need to go to the application manager, select the hated program and find the “Disable” button. Following this, you can also clear the application cache.
The result will not be long in coming: the marked applications will disappear from the menu and will no longer remind you of themselves. However, it is not always possible to completely get rid of them: most likely, some programs will take up several megabytes in the memory card bins, but do not forget about the main advantage. A disabled application will not launch when the device is turned on, thereby saving RAM and, accordingly, the charge of the device. Not bad, right?
Be that as it may, we should not forget that many system applications affect the operation of the smartphone as a whole, and therefore you should experiment with disabling them with extreme caution.
Are there many similar unnecessary programs is on your smartphone? Share your answers in the comments.
Applications in the operating room Android system- a very simple process, a few touches on the screen and you're done. However, there are applications that refuse to be removed. This situation occurs because some applications are installed as a device administrator, while others are already installed (pre-installed) by the device manufacturer and the user does not have rights to remove them.
For complete removal pre-installed applications will require root rights. If you don't want to root your device, you can try disabling preinstalled programs, so that they do not run along with Android and do not take up space in RAM. So, how to remove uninstallable applications.
Device administrator applications require more rights for their full functionality. This should not be confused with applications that require , it’s just that administrator programs need more permissions within the framework of existing user rights. For example, to install protection or remote lock smartphone, tracking it via GPS, etc.
If the application you installed is not uninstalled, then go to the settings of your Android device, go to the “ Safety" and further in " Device Administrators", in which uncheck the program being deleted that it is an administrator.
After this, the application will be uninstalled without any problems.
Removing or disabling pre-installed applications
There are manufacturers who abuse the installation of their programs that cannot be removed. You can delete them, as mentioned above, only by obtaining root rights on the device. But what to do if you don’t want to do this or the smartphone/tablet is under warranty and its root serves as the basis for removal warranty obligations? In this case, you can try to stop pre-installed applications. To do this, do the following:
Disabled pre-installed applications should disappear from the menu and will no longer launch with Android, and also take up RAM, which in budget smartphones will a big plus, where it is always in short supply.
The firmware of many smartphones and tablets running Android contains so-called bloatware: applications pre-installed by the manufacturer of dubious usefulness. As a rule, it is not possible to remove them in the usual way. Therefore, today we want to tell you how to uninstall such programs.
In addition to bloatware, virus software cannot be removed in the usual way: malicious applications use loopholes in the system to pretend to be the administrator of a device for which the uninstallation option is blocked. In some cases, for the same reason, it will not be possible to remove completely harmless and useful program like: she needs administrator rights for some options. System applications like the Google search widget, the standard dialer, or the default one are also protected from uninstallation.
The actual methods for removing uninstallable applications depend on whether your device has root access. It is not required, but with such rights you will be able to get rid of unnecessary system software. Options for devices without root access are somewhat limited, but in this case there is a way out. Let's look at all the methods in more detail.
Method 1: Disable Administrator Rights
Many applications use elevated privileges to control your device, including screen lockers, alarm clocks, some launchers, and often viruses that masquerade as useful software. The program to which access is granted Android administration, you won’t be able to uninstall it in the usual way - if you try to do this, you will see a message stating that uninstallation is impossible due to active options device administrator. What to do in this case? Here's what you need to do.
- Make sure that developer options are enabled on your device. Go to "Settings".
Pay attention to the very bottom of the list - such an option should be there. If it is not there, then do the following. At the very bottom of the list there is an item "About the phone". Enter it.
Scroll to "Build number". Tap on it 5-7 times until you see a message about unlocking developer options.
- Enable USB debugging mode in the developer settings. To do this, go to "Developer Options".
Activate the options using the switch at the top, then scroll through the list and check the box next to "USB Debugging".
- Return to the main settings window and scroll down the list of options to the general block. Tap on an item "Safety".
On Android 8.0 and 8.1 this option is called "Location and Protection".
- Next, you should find the device administrators option. On devices with Android version 7.0 and lower, it is called this "Device Administrators".
IN Android Oreo this function is named "Device Administrator Applications" and is located almost at the very bottom of the window. Enter this settings item.
- A list of applications that are allowed to additional functions. As a rule, there are inside remote control device payment systems(S Pay, ), customization utilities, advanced alarm clocks and other similar software. There will probably be an application on this list that you can’t remove. To disable administrator privileges for him, tap on his name.
On latest versions OS from Google this the window looks like this:
- In Android 7.0 and below - there is a button in the lower right corner "Switch off", which you need to press.
- You will automatically return to the previous window. Please note that the check mark next to the program for which you have disabled administrator rights has disappeared.
In Android 8.0 and 8.1 - click on "Disable device admin app".
This means that such a program can be removed in any available way.
This method allows you to get rid of most uninstallable applications, but may not be effective if powerful viruses or bloatware embedded in the firmware.
Method 2: ADB + App Inspector
Difficult, but the most effective method getting rid of uninstallable software without root access. To use it, you will need to download and install it on Android computer Debug Bridge, and on the phone - app Inspector.
Having done this, you can proceed to the procedure described below.
- Connect your phone to your computer and install drivers for it, if necessary.
- Make sure that the archive with ADB is unpacked to the root system disk. Then open "Command line": call "Start" and type the letters in the search field cmd. Click on the shortcut right click mouse and select "Run as administrator".
- In the window "Command line" write the commands sequentially:
cd c:/adb
adb devices
adb shell - Go to the phone. Open App Inspector. A list of all applications available on your phone or tablet will be presented. alphabetical order. Find the one you want to delete among them and tap on its name.
- Take a close look at the line "Package Name"— we will need the information recorded in it later.
- Go back to your computer and « Command line»
. Type the following command in it:
pm uninstall -k --user 0 *Package Name*
Instead of *Package Name*, enter the information from the corresponding line from the page of the application to be removed in the App Inspector. Make sure the command is entered correctly and press Enter.
- After the procedure, disconnect the device from the computer. The application will be deleted.
The only drawback of this method is that it removes the application only for the default user (the “user 0” operator in the command given in the instructions). On the other hand, this is a plus: if you deleted a system application and encountered problems with the device, it’s enough to simply do this to return the deleted one to its place.
Method 3: Titanium Backup (Root only)
If your device is rooted, the procedure for uninstalling uninstallable programs is greatly simplified: just install Titanium Backup, an advanced application manager that can remove almost any software, on your phone.
This method is the simplest and convenient solution problems with uninstalling programs on Android. The only problem - free version Titanium Backup is somewhat limited in its capabilities, which, however, are sufficient for the procedure described above.
Conclusion
As you can see, uninstallable applications are quite easy to deal with. Finally, we remind you - do not install dubious software on your phone from unknown sources, because you risk running into a virus.

Android OS is the best because you can do absolutely everything in it, even remove system applications that cannot be removed through standard options in the Settings menu. And many of them are never used by the user, so this procedure only optimizes the system.
A necessary condition in order to be able to remove system applications for Android is obtaining root rights. They will be needed in many more cases and will greatly expand the capabilities of the device, so obtaining them can be considered a must for any smartphone owner. This can be done using different software: Kingo Android ROOT, Unlock Root, Framaroot, etc.
After obtaining such rights, you need to install Explorer, which will give access to initially hidden system files. It is best to use ES Explorer or Root Explorer.
Two ways to remove protected applications on Android
Most effective way , but also the most dangerous is to simply delete applications directly from the file system. They are located on the path /system/app, that’s where you need to select unnecessary files With apk extension, but do it very carefully, being aware of every action.
Additionally, you can delete odex files there, separate folders with the names of applications, and along the path /data/app updates of these “uninstallable” programs.
Finally, along the /data/data path there are cache files that can also be erased.
It is best to remove pre-installed applications, such as live wallpapers, etc.
Remember! System files With Android shortcut You can only wash it if you have a clear understanding of why it is needed.
Easier way to remove- through special program Root Uninstaller Pro. It has a fairly simple and clear interface, in it you can quickly select the desired software and erase it.
Great advantage this method that it is possible not to destroy software completely, and also “freeze” it with the possibility of further restoration. Such a “freeze” completely stops a specific software.
Through ES Explorer itself, you can also remove protected applications from a special GUI rather than by accessing directly to file system. To do this, you need to follow the path to the Explorer menu: “Libraries” – “APPs” – “User” – “System”, select the ones you need from the expanded list and uninstall them completely with one simple click.
