There was an android error in the calendar application. System application disabled. Solving the problem for ordinary users

Official firmware Android are different stable work system applications, but what to do when, for example, launching contacts, Process Acore appears? In most cases the problem is recently installed programs Oh. There are several options to solve the problem. Let’s take a look at what “Android Process Acore has encountered an error” and how it can be fixed.

Often the Android Process Acore error occurs on Samsung and NTS tablets and smartphones. But this problem also appears on mobile devices from other companies. Before looking for methods to eliminate it, it is necessary to analyze the situation and identify the causes of the error.

System application disabled

All main processes and applications on the phone start when the operating system boots. If for some reason you disable them, they may give an Android Process Acore error when launched. You cannot accidentally remove processes from running ones, because to do this you need to go to the application manager and stop this service. A much more likely option is to disable the system application as a result of the mobile phone software being infected by a virus. A regular worm, not to mention Trojans, is capable of renaming and controlling system processes and services on your phone.

Incorrect synchronization with system applications

The appearance of the Android Process Acore error is associated with the installation of several applications with similar functions that do not synchronize correctly with the contact list. Instead of contacts, a calendar, clock or other system application. In this case, both programs access the same process, assigning different values to it at the same time, which causes a synchronization error.

Important system files have been deleted from the phone memory

Another common cause of Android Process Acore error is deleting system files. Erase them in the usual way will not work, so this is possible either on rooted smartphones or through special file managers. As with disabling system applications, their deletion may also be the result of a virus entering the mobile phone’s operating system.

Installing custom firmware

Those who like to put it on a smartphone custom firmware We have also encountered a similar problem more than once when calling the contact list or calendar. The reason is the incompatibility of the installed software with a mobile phone model.

For more information about the error, see the video below.

Error resolution methods

The problem with the occurrence of the Android Process Acore error is solved in several ways different ways. You can resort to pre-factory settings. But before that, it is recommended to use more “gentle” methods, which we will consider below.

Disable the conflicting application

In more than 80% of cases, you can solve the problem with the Android Process Acore error by deleting the conflicting application. It is enough to remember what program or game you installed in last couple days and disable or delete it from your phone. If you don’t remember exactly what you put on your mobile phone in Lately, or are not sure about a specific utility, you need:

Open the Android main settings menu. We find the desired tab in the pull-down curtain or on the home screen.
Go to the “Applications” tab.
In the menu that appears, select “working” by side swiping or clicking on the desired item.
This will display a list of running this moment applications and processes. It is necessary to select all non-system programs one by one and stop them.
After stopping each application, check the resolution of the Android Process Acore error by launching the phone book, contacts or calendar.

If this method did not help, then you need to reset the settings and clear the cache of all applications. To do this, just click on the menu located in the upper right corner and select the appropriate items in the window that appears. After finding the “culprit” of the error, this application It’s better to completely remove it from your mobile phone and download another alternative. When you restart the OS, it will start again as a process and will appear in the task manager.

Complete clearing of phone contacts list

If the problem occurs only when opening the contact list, then completely clearing it will help. Before performing this operation, it is recommended to create backup copy data on your Google account or any other storage.

So, to clear contacts on your phone, follow these steps:

Open the Android main settings menu.
Select the applications tab.
Find “contacts” in the list and select applications by clicking to clear the cache, as well as clear data by clicking on the appropriate items.
We repeat similar actions with another application from the list, “Contact Storage”.

You can see how to properly clear application data and delete their cache from the video below.

Changing system files

If the values of system files are damaged or mismatch, you can try to solve the problem by changing them through the explorer on your mobile phone. To do this you need to log in to any file manager and open the executable file located at /system/csc/others.xml. It contains the execution string TRUE, the value of which must be changed to false.

For rooted devices, a necessary system file may be lost due to unsuccessful application cleaning. Need to download deleted documents through the Internet. Using the Titamium backup utility can also help, which allows you to start the logsProvider 2.0.d process, the stop of which causes the Android Process Acore error to occur.

Extreme measures

If none of the above methods for solving the problem helped, you should reset your Android settings to factory settings. To do this, go to settings and select the “restore and reset” tab, where you will be able to required function. This will result in complete loss of user data, so it is recommended to back it up first.

Another “extreme” solution would be to flash the mobile phone to another OS, since the Android Process Acore error occurs precisely as a result of a violation system processes in the Android kernel.

The world's most popular OS is known for its instability. Every Android user has encountered one error or another at least once, but not everyone found a solution. It’s definitely not worth changing your device right away because of this. Next, we will look at the main errors on Android and how to solve them. Often there is no error, but only a small function that can be solved in a couple simple actions.

Sometimes Android may display system errors. There's nothing wrong with that

This section contains problems that are usually easy to fix or not required at all. Often the cause may not even be the device itself. But there are also some that make users nervous.

Low memory

This cannot be called a bug, but rather a limitation of the capabilities of your device. Yes, indeed, on old, and even new, devices, the internal memory sometimes runs out abruptly. The problem is solved very simply.

If you use applications such as Instagram, VK, then the cache is definitely to blame, which they accumulate very quickly and in large quantities.

Go to “Settings”, select “Applications”.
Often those who occupy the top are immediately brought to the top greatest number memory. Click on them.
Select the “Clear cache” item.

There is nothing wrong with the “insufficient space in device memory” error; it can be easily resolved

This cleaning can free up to several gigabytes. free space. You can also completely erase the data in the application, but then you will have to “log in” again.

Because of memory full errors may occur under different numbers. For example, error 919, when the application cannot start due to insufficient space.

On some devices (not all), you can transfer some programs to a memory card. This will free up even more space. This is done from the same item in the settings. It is better to monitor the availability of free space more often so that the gadget always works properly and without brakes.

Wi-Fi Authentication Error

Also one of the most popular problems on Android. Although in fact, very rarely the problem lies in the device. More often than not, the cause is the router, or more precisely, its incompatibility with your device. The problem is resolved quite quickly.

The first method, the most obvious, is simply to check that the entered password is correct. After all, authentication is nothing more than checking the security key. Therefore, try to forget the problematic network and then re-enter the password.

If everything is fine with the password, but Wi-Fi still doesn’t want to connect, then the reason definitely lies in the router settings. The fact is that its data encryption type may be older than that used on the Android device, or the device does not support any network standard.

In this case, you need to go to the router settings.

Open the browser. IN address bar enter “192.168.1.1” or “192.168.0.1”.
In the window that appears, enter your username and password: most often these are admin and admin. If you have others, then enter yours.
Now you need to find the settings Wi-Fi security. Here we set a mixed encryption type or network authentication“WPA-PSK/WPA2-PSK2 mixed”, and also select automatic selection network standard.

After this, problems with connecting to Wi-Fi should disappear.

Syntax error

The error is that the file that installs specific application, is incorrect or was not launched correctly. Additionally, there may be a failure during installation, which also results in a syntax error.

The fix is pretty easy. First, make sure that the file you downloaded has apk format. Because it is files of this format that are application installers on Android. Secondly, delete this downloaded file and re-download it and then reinstall it. It makes sense to try downloading the file from another site. This usually clears the error.

loading error

This often happens on older devices, but on new ones this problem no longer occurs. Thing is standard manager downloads are glitchy, making it difficult to download anything from the internet. The error is fixed quite easily.

You just need to download a new download manager. ES Explorer may be perfect for these purposes. It has a good built-in download manager.

Android Keyboard AOSP

This keyboard itself is not the best. In addition, it is not very well optimized on some firmwares, which causes errors. Solving them is simple.

Disable voice input in your keyboard settings.
Reset the settings, erase the cache and data of the application that is responsible for the keyboard.
Just download from Google Play Market any other keyboard.

Errors with Google Accounts

There can be two errors: the account does not want to synchronize or does not want to be added. The first can be present on both old and new devices, while the second is gradually becoming a thing of the past. Fixing all this is not that difficult.

Check the quality and stability of your Internet connection: mobile network or Wi-Fi must work normally, otherwise the reason may lie in them.
If an account has already been added but is not syncing, simply disable it, restart your device and log in again.
If your account refuses to connect, first make sure your login and password are correct.
Disable two-step sync in your account settings.
Enable automatic synchronization and data transfer to background, then reboot the device.

Netalpha virus

A new problem encountered by Android users. This malware makes it difficult to work with your phone and prevents you from removing it. The problem is quite serious because it involves only two solutions, one of which is very radical.

Reset the system to factory settings. More details on how to do this are at the end of the article.
If you have root rights, you can download Lucky Partner and remove the ill-fated application.

Com.android.snap

Occurs when using various applications: popular photo editors, messengers. This inscription often appears on a black background, which is very distracting, and programs may simply close.

It is believed that this glitch is caused by malware, so many people advise simply installing an antivirus. However, you can do without it using systematic methods.

Go to the settings menu, to the “Applications” item.
We look for the application “com.android.snap” there.
We delete its data, clear the cache and stop it.
You also need to uncheck the “Send notifications” checkbox.

After this, the program will stop annoying you, and you will no longer see this message on the black screen. If you have an antivirus installed on your device, you can remove the bug using it. But, as practice shows, this error rarely occurs on devices with antivirus software.

Besides com.android.snap, there is also com.android.systemUI. What they have in common is that they are Trojan-type viruses. Accordingly, the program is neutralized in the same way.

Com.android.phone

If the system says that the application is com.android. phone an error occurred, which means the problem lies in the program that is responsible for making calls on your tablet or smartphone. An error appears on various reasons. Therefore, the solutions will be different for everyone.

Try unchecking the settings in the settings. automatic synchronization dates and times via the Internet and then put them back. After that, reboot your phone and set correct date and time on your own.
Erase data and delete the Phone app cache.
You can simply download any “dialer” that will replace the standard one, since the application store is full of them.

Android.process.acore

If an error occurs with android.process.acore, then the problem is no longer related to either the dialer or viruses. The reasons may be the following:

missing system files;
some system application has stopped working;
There are several applications on the device that perform almost the same functions, and they do not synchronize correctly with system applications

The difficulty of solving a problem depends on the cause of its occurrence. Most often, it is resolved simple removal all contacts through the device settings. If you synchronize all your contacts with Google before doing this, you won’t lose anything at all.

There is an option to reset all applications through the corresponding menu item. This also often solves the problem without losing any data. If you have optimization applications installed Wi-Fi work, then you should try to remove them too. Often the reason lies precisely in them.

Adroid.process.media

The Android Process Media error occurs for two reasons: Media Storage or Download Manager. Both can be solved quite simply. There are two general methods that almost always work flawlessly.

First way

Clear cache and data from apps Google Service s Framework and Google Play Market.
Stop Google work Services Framework(must be done in this order).
Clear the cache of this utility again.
Open Google Play, find problematic application. When you receive an error message, click OK.
Reboot your gadget and restore disabled Google services.

Second way

Completely stop Google sync account. This can be done from the account settings: in the “Synchronization” item, you must clear all the checkboxes.
Erase the data and stop the Gallery utility.
Similarly, disable the "Download Manager".
Reboot your device.

After using one of these methods, the problem will disappear.

Invalid batch file

The error often occurs when updating an application. If this happened during an update, you need to clear the cache of this application. Alternatively, you can try to manually download apk file program and install it again. If this doesn’t help, delete your Google account, reboot your device and log in again.

PACKADGE FILE INVALID

We delete the cache and data of the problematic application.
We go to Google Play and install it there.
We clean Google Play and Google Service Framework data.
We update the application via Mobile Internet, not Wi-Fi.

Installation unsuccessful error

Reinstall the problematic application.
Clear the cache and delete Play Market data.
Disconnect the memory card from the device.
Delete the folder.android_secure.
Reinstalling the application.

Error number...

These errors can be more serious. However, they are often resolved in a few simple steps. It all depends on the number of this very error. Moreover, Google provides a minimum of information about solving various errors.

11, 101, 504, 506, 491, 495, 413, 941, 921, 920, 481, RH01: Google Play and account problems

These applications or account problems are solved using almost the same methods. Android may issue “Error code 11” when work Play Market. Problems often occur under specific numbers precisely with this Google service. It has been noticed that error 11 often occurs when installing or updating WhatsApp.

Another popular error due to which the Play Market also does not want to download the application is 504. It occurs on Android due to the same reasons as other problems with downloading programs, so the elimination methods are identical. The same goes for other errors.

Problems are solved in several ways, and each of them is suitable for most similar errors.

We exhibit right time and check the operation of the Internet connection.
Checking the amount of free internal memory: it should be higher than the size of the programs that are having problems loading.
After that, try simply restarting your phone or tablet. Google Play Market errors on Android are often solved in this way.
Resetting the settings. Using the method indicated above, open the window Play apps Market, then clear the data and cache. Then go to the Application Store again. Alternatively, you can also uninstall all updates in the same window, which will return the program to its original state. original form when purchasing a device.
You can do the same with the Google Play Services program if the previous method did not help. If this does not help, then you can try to do a similar operation with Google Services Framework.
The problem could also be a disabled application " Google Accounts" We go into its window, if we see that it is turned off, then we turn it on. You should also enable the “Download Manager” if it was turned off.
We try to log out and log back into our Google account. This is done from the settings. There we find the item “ Accounts" and select Google.

24

Error 24 occurs when installing an application on Android, when some kind of failure has occurred, and some of the files have already been installed. Or you had this application before, you deleted it, and then decided to download it again. The problem is resolved quite quickly.

Launch any file manager.
We find the directory “sdcard/Android/data/data”, it contains files related to this application. They will contain the name of the program in the name, so they will be quite easy to distinguish from the rest.
We do the same in the “data/data” directory.

After this, the error should disappear and the application should install without any problems.

498

This error occurs when loading an application. There may be several problems, but they are quite easy to solve.

Check your internet connection.
Clear the cache of several programs, and first of all - Google Play.
Wait a couple of hours. It is quite possible that the reason lies in Google servers. If so, they will fix it quickly.

After this, the error should disappear.

923

We delete a Google account and several unnecessary programs, clear the cache.
Clearing the system cache:
1. Go to Recovery (ON button and volume control button and hold).
2. Choose Wipe Cache Partition.
3. Reboot the device.
Reboot the device.
Login to Google again.

403

There is a so-called Dalvik cache. Due to its filling, we again do not want to install certain programs. To solve the problem, we clean the data and disable first “Google Accounts” and then the Google Play Store.

Rh01 /rpc:s-5:aec-0 /RPC:S-3

The system cannot receive information from the server. To fix the problem, you need to do the same as with other similar errors.

Clear the cache and remove unnecessary unnecessary applications.
Erase data and stop Play Market and Google Services Framework.
As described in the previous error (403), delete the cache through Recovery.

492

Content from Google Play is not loading again.

We clear the data and stop Google Play Services.
We do the same with Google Play Market.
Delete the dalvik cache if the problem is still present. However, this can only be done if you have root access.
If you don’t have root rights, then you’ll just have to do a full system rollback.

911

It also doesn't allow you to download apps.

We clear the data, cache, stop Google Play Market.
Try connecting to a different Wi-Fi network or using mobile data to download the app.

Rpc:aec:0]

Problems receiving data from the server. Deleting all synchronized accounts can help. Then we clear the cache and Play Store data, and then restart the smartphone or tablet.

A similar error is RPC:S-3. In this case, you only need to delete your Google account, after which you can try to connect another one or the same one.

927

This fault is independent of our device. The reason lies in the fact that the program is updated by the developers. Therefore, if we want to install or update it, we will not be able to do this. It's just worth trying to install it again after 30 minutes or later.

How to solve any errors

And finally, a method that is suitable for fixing any problems. But you should always resort to it last. This . Full reboot Android systems will delete all user data, so you should first transfer the most important data to a memory card or save it in cloud services.

Open the settings.
Select the item “Reset and recovery”, on different devices it can be called differently and can be located either in the settings menu itself or in the “System” item.
Click "Reset".

After this, the device returns to factory settings, all problems disappear.

Now you know how to fix the vast majority of errors on Android. There are many more of them, but the rest of the problems have similar solutions, especially Google Play service errors, which are so rare that there is no data about them yet or have already been corrected by the developers.

As many years of experience have shown, very often owners of devices with Android OS are faced with various errors and problems, some of which simply confuse some users. For example, a fairly common case is when the device shows a notification, android error has occurred process core.

How to fix the problem? What should a novice user do if he has only recently purchased a phone and does not know all the intricacies of his device? Why did it happen this error? In this material we will answer all questions related to this problem. In the future, you will be able not only to quickly bring your smartphone back to life, but also to prevent such errors from occurring.

For what reasons does this error occur?

First, you need to understand why this error occurs on your phone. Moreover, it is worth noting that it can appear in almost any version of the Android operating system, regardless of the manufacturer.

So, here's the list possible reasons this system error appears:

Your phone has deleted system files or folders necessary for correct operation operating system;
The operating system cannot operate stably and correctly due to the disabling of one of the system applications;
The device has several programs or widgets installed that have similar functions that conflict with each other, for example, synchronizing data from a contact list or viewing a forecast, email clients.

How to fix android process acore error: 2 ways

Even if you have a similar problem, don’t immediately panic and go to the store for a new phone. We also do not recommend that you contact service center and just give it away cash. You can fix this problem yourself, even if you recently purchased a device with operating system Android. We have roughly divided the list of solutions into two categories, starting from ordinary users those who have just started working with this OS, ending with advanced users.

Method 1 - for beginners

As practice shows, this error mainly occurs when working with the contact list on your smartphone. For example, you are trying to add new contact to the notebook or erase the entry, edit. To fix the error you will need to do the following:

Go to Settings and select the Applications tab.
Find the "Everything" tab and then "Contact Storage."
Now find the “Erase data” option and click on it. Attention! All your contacts will be deleted from mobile phone, however the error will most likely go away. If you previously created individual copies V vCard format or synchronized your phone book in Google services, then it will be easy to restore all data.

Another reason why this error may appear is incorrect work"Calendar storage". To fix the error, do the following:

Go to your phone's Settings.
Select “Applications” and in the “All” tab find “Calendar storage”. Click this button and if the service has been disabled, select Enable.

Also, the problem sometimes occurs when installing applications that optimize wireless Wi-Fi networks. IN in this case We recommend that you view full list of all installed programs on your smartphone, determine which of them are designed to optimize wireless networks and remove them one by one.

One of the extreme methods is to return to factory settings.. Just keep in mind that all data will be completely deleted from your phone, both personal data and all applications, as if you had just purchased the phone from a store.

Method 2 - for advanced users

If you are a confident Android user and have worked with the file system, built-in services and widgets, then when a message appears that an error has occurred android process acore, you can use the method described here. You can fix the problem by editing the system file. To do this you need to do the following:

IN file system go to the following path: /system/csc/others.xml and open it with any built-in editor.
Find the line in the file TRUE and change the value TRUE to FALSE .
Once the value is changed, save the file and restart the device. We recommend that you create backup copies of the files you edit.

In general, we can conclude that this error is not critical for the user and can be eliminated in a few clicks. Remember that you should resort to the last method with data rollback only if all the methods described in the article do not fix the problem. Rolling back removes the application that automatically generates the error, so it no longer appears. Data rollback can be done using: standard menu Android operating system and special keys. Read more in detail in a separate article, the link to which is given above in this material. If you still have any questions about this problem, leave your comments and our specialists will definitely help you solve them!

Many users of smartphones with operating Android system, have encountered the following problem - how to fix the android.process.acore error on your smartphone. For an unprepared user or for beginners, this causes panic and they do not know what to do, and some even “bury” their phones prematurely. But “the devil is not as terrible as he is painted.”

To fix the android.process.acore error, you must first find the root of the problem. Analyzing various resources and personal experience, we decided in this article to describe the most common reasons this type of error occurs.

We hope that many this information will help you solve the problem without panic.

Reasons for the problem

There are 3 main reasons for the android.process.acore error to appear:

the system application is disabled, which is why Android cannot function normally;
several applications with similar functions are installed at the same time, which do not synchronize correctly with the contact list, calendar or other system application;
Important system files have been deleted.

Error resolution methods

There are several methods that may help fix the android.process.acore error on your device. These methods are designed for both casual and advanced users. Carefully read all the options and choose the one that you can implement. Do not try to solve the problem on your own by changing system files unless you are a professional.

Solving the problem for ordinary users

Most often the error occurs when working with phone book, when you try to add, save, edit or delete any contact. Treatment: we try to go to Settings/../Contact storage (it may be called differently, but the essence is clear) and find the option “Erase data”. In many cases, it helps fix the situation, but you destroy your entire contact list. There's nothing you can do about it, you'll have to sacrifice. For those who have the ability to synchronize with a Google account, this the way will pass painless.

One of the reasons for the android.process.acore error could be that Calendar Storage is disabled or other programs are disabled. In order for the problem to go away, go to Settings/Applications, there we find extra menu and click on “Reset settings”. This method, of course, if it works, is good because personal data is not lost during the reset.

You can fix the android.process.acore error by removing applications for optimization wireless network Wi-Fi, in some cases the problem disappears.

An effective method is also “Reset to factory settings”. This action will cancel everything individual settings user, but this is not as critical as losing contacts. For help, read the instructions for the Recovery item for your model.

Troubleshooting for advanced users

Another way to deal with the problem can be recommended for experienced users Android. It consists of system file changes:

/system/csc/others.xml. It contains the line:

TRUE,

which needs to be edited to get the following:

false.

Let us remind you once again that this method is ONLY for experienced ones!

If your device is rooted, it is quite possible that you unsuccessfully cleaned system applications and files, resulting in the android.process.acore error. In this case, you will have to search on the Internet deleted files exactly for the version you are using Android firmware, return them to their place and set the appropriate rights.

Also, for devices with root rights, the solution to the problem is to enable the possibly previously disabled logsProvider 2.0.d process via Titamium backup.

Extreme measures

And finally, when all else fails, they resort to radical methods, which consist in complete cleaning device memory with loss of all data. This way, applications that generated the android.process.acore error are removed from the system.

And if hard reset didn't help, only one possible option All that remains is to flash the smartphone. This case is relevant for “rooted” devices, during the cleaning process of which important system files were deleted and could not be restored.

If you have used another method to fix the android.process.acore error, please let us know your success in the comments. Good luck!

Users of Android OS devices may encounter various types of errors. Some of them do not block the operation of the entire system, while others can cause a complete stop in loading system files, and as a result, an inoperable gadget.

One of the most common problems on Android devices is the android process acore error. It causes one or more applications to stop working.

If the user does not have enough rights simple user device, then he can get root rights, and the owner of these unlimited rights gets access to system files. This is where the adventure begins - out of ignorance or inexperience, the owner begins to disable or even delete, as it seems to him, files that are not necessary for the system to function, and this is the main reason for the appearance of the android process acore error.
The application was accidentally stopped, so it cannot function normally.
The user has installed two or more applications with the same functions, so the system cannot synchronize work, for example, with the Contacts or Calendar applications, which is the cause of the error. That is, in this case, a conflict arises between applications.

How to prevent system problems?

How to fix android process acore error? There are several options, which are described below.

Since the problem occurs in the system itself, we will have to edit system partition. But an unsure user may not understand how and in what sequence changes need to be made, which can lead to failure of the device itself. mobile device. It takes some knowledge to fix this problem correctly.

Overwriting contacts

Most often, a problem occurs in the operation of the system “Contacts” folder. When you try to add or delete an entry, you can see an unfortunate message on the screen.

How to fix:

This is a solution, but no one wants to lose all the data at once, so you should first synchronize the folder with the service Google Contacts or make a backup copy. It can be simple in the old-fashioned way it's stupid to write a list on a piece of paper if you don't know how to reserve or synchronize necessary information. After the list is cleared, you can try to add the contact to system folder, and if the annoying message appears again, then try doing the same with the “Calendar” section.

If third-party software was installed

If you have recently installed applications to optimize your Wi-Fi connection, then this may be the cause of the problem android process acore has stopped. Also interfere normal operation Devices can also use other optimizers and applications.

Go to the main settings menu, find the “Applications” line.
Now pay attention to the “Running” tab - you will see a complete list of all currently running programs. Try to turn them off one by one and check your smartphone.
After stopping recently installed software go to the “Contacts” folder, try making changes to the list.
If this method does not bring any changes, then you can find the option “Clear the cache of all applications” in the all applications tab at the bottom, and then check the box next to the option to reset all applications.

Sometimes this method helps get rid of the error, but if not, then move on to another method.

Editing system files

This method is suitable for confident users who can easily understand system files.

Launch the file manager and go to the directory at system/csc/.
Now you need to find and edit the file called others.xml.
In the file that opens, you will see its contents, in which you need to find the word True and enter False instead.
Restart.

Note! If you have not found the desired directory, then it is unlikely that you will be able to get rid of the problem using this method.

If all of the above methods did not help to achieve success, and still a message appears that android app process acore an error occurred, then there is nothing left to do but reset the device to factory settings.

Before resetting your settings, make a backup copy of all your files so that you can install them back later, or synchronize with Google services, and then when you log into your account they will be downloaded to your smartphone.

Reflashing the device

And the last, risky way is to flash your OS version. Find information about your version from the main menu of the device in the “About smartphone” section, write down the version number, now you need to go to the manufacturer’s website and download setup files and drivers. But some manufacturers do not provide such information on their official websites, directing the user to service department– it is of course correct that the restoration will be carried out by a professional.

Conclusion

So that you don't encounter anything like this in the future. system message, do not root the device, do not touch the system partition. Even if you don’t need some functions for work, it will give a guarantee proper operation system files.
