Failure in the encryption system what to do. Android encryption failed: what to do? Encryption and its meaning

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

Sometimes Android may give system errors during operation. There's nothing wrong with that

This section contains issues that are usually easy or not required to fix. Often their cause may not even be the device itself. But there are also those that made users nervous.

Out of memory

This cannot be called a mistake, rather, a limitation of the capabilities of your device. Yes, indeed, on old, and even on new, devices, internal memory sometimes ends 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.

1. Go to "Settings", select "Applications".
2. Often, those that take up the most memory are immediately displayed at the top. We press on them.
3. Select "Clear Cache".

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

Due to overflowing memory, errors under different numbers may occur. For example, error 919, when the application cannot start due to lack of space.

On some devices (far from all), you can transfer some of the 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.

WiFi authentication error

Also one of the most popular problems on Android. Although in fact, very rarely the problem lies in the device. More often, the router becomes its cause, or rather, its incompatibility with your device. The problem is solved pretty quickly.

The first method, the most obvious one, is simply to check if 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 in order with the password, but Wi-Fi still does not want to connect, then the reason definitely lies in the router settings. The fact is that its type of data encryption 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.

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

After that, Wi-Fi connection problems should disappear.

Syntax error

The error lies in the fact that the file that installs a certain application is incorrect or was not launched correctly. Also, installation may fail, which also results in a syntax error.

Fixing this is pretty easy. First, make sure the file you downloaded is in apk format. Since it is the files of this format that are the installers of applications 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 up the error.

loading error

It happens often on older devices, on newer devices this problem no longer occurs. It lies in the fact that the standard download manager crashes, which makes it difficult to download anything from the Internet. The error is fairly easy to fix.

All you have to do is download the new download manager. ES Explorer can be excellent for these purposes. It has a nice built-in download manager.

AOSP Android Keyboard

This keyboard itself is not the best. In addition, it is not well optimized on some firmware, which causes errors. It's easy to solve them.

• Turn off voice input in the keyboard settings.
• Reset settings, clear 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 be synchronized or does not want to be added. The first can be present on both old and new devices, and the second is gradually becoming a thing of the past. It's not that hard to fix this.

• Check the quality and stability of your Internet connection: the mobile network or Wi-Fi should work fine, 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 username and password are correct.
• Turn off 2-step sync in your account settings.
• Turn on automatic synchronization, as well as data transfer in the background, and then restart the device.

Netalpha virus

A new issue that is encountered by Android users. This malware makes it difficult to work with the phone and does not allow itself to be removed. The problem is quite serious, since it involves only two solutions, one of which is very radical.

• Resetting the system to factory settings. More details on how to do this at the end of the article.
• If you are rooted, you can download Lucky Partner and remove the ill-fated app.

Com.android.snap

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

This failure is believed to be caused by malware, which is why many advise simply installing an antivirus. However, you can do without it by systemic methods.

1. We go into the settings menu, in the item "Applications".
2. We look for the application "com.android.snap" there.
3. We delete its data, clear the cache and stop.
4. You also need to uncheck the "Send notifications" box.

After that, the program will stop annoying, and you will no longer see this inscription on a black screen. If an antivirus is installed on the device, then you can remove the bug using it. But, as practice shows, this error rarely occurs on devices with antivirus programs.

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

Com.android.phone

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

1. Try in the settings to uncheck the automatic date and time synchronization via the Internet, and then put them back. After that, restart your phone and set the correct date and time yourself.
2. Wipe your data and clear the cache of the Phone app.
3. You can simply download any “dialer” for yourself, which will replace the standard one, since the app store is full of them.

android.process.acore

If an error occurred with android.process.acore, then the problem is no longer associated with either the dialer or viruses. Here the reasons may be the following:

• required system files are missing;
• the work of some system application has been stopped;
• there are several applications on the device at once 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 solved by simply deleting all contacts through the device settings. If you sync all contacts with Google before that, then you won’t lose anything at all.

There is an option to reset the settings of all applications through the corresponding menu item. This also often eliminates the problem, and you do not lose data. If you have Wi-Fi optimization applications installed, then you should also try to remove them. Often the reason lies precisely in them.

android.process.media

Android Media Process Error occurs for two reasons: Media Storage or Download Manager. Both are pretty easy to fix. There are two general methods that almost always work flawlessly.

First way

1. Clear cache and data Google Apps Services Framework and Google Play market.
2. Stop the Google Services Framework (in that order).
3. Clear the cache again with this utility.
4. Open Google Play, find problematic application. After receiving the error message, click OK.
5. Reboot the gadget, restore the disabled Google services.

Second way

1. Completely stop Google sync account. You can do this from the account settings: in the “Synchronization” item, you must uncheck all the boxes.
2. Erase the data and stop the Gallery utility.
3. Disable "Download Manager" in the same way.
4. Reboot your device.

After applying 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 for this application. In addition, you can try to manually download the apk file of the program and install it again. If this does not help, delete the Google account, reboot the device and log in again.

PACKADGE FILE INVALID

1. We delete the cache and data of the problematic application.
2. Go to Google Play and install it there.
3. We clean Google data Play and Google Service Framework.
4. Update the app with Mobile Internet and not Wi-Fi.

Installation unsuccessful error

1. Reinstalling the problematic application.
2. We clear the cache and delete data from the Play Store.
3. Disconnect the memory card from the device.
4. Delete the .android_secure folder.
5. Reinstall the application.

Error number...

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

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

These applications or accounts are solved by almost the same methods. "Error code 11" Android may issue when the Play Market is running. Often there are problems under specific numbers with this particular 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 troubleshooting 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.

1. We set the correct time and check the operation of the Internet connection.
2. Checking the amount of free internal memory: It must be higher than the size of the programs that are having problems loading.
3. After that, try simply restarting your phone or tablet. Google Play Store errors on Android are often solved in this way.
4. We reset the settings. Open the window as described above. Apps Play Market, then clear the data and cache. Then go back to the App Store. Alternatively, you can also remove all updates in the same window, which will return the program to its original form when you purchased the device.
5. You can do the same with the program Google Services Play" if the previous method did not help. If this does not help, then you can try to do a similar operation with the Google Services Framework.
6. The problem may also lie in the disabled Google Accounts application. We go into its window, if we see that it is off, then turn it on. You should also enable the "Download Manager" if it was turned off.
7. Trying to log out and log back into your Google account. This is done from the settings. There we find the item Accounts and choose 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 solved pretty quickly.

1. We launch any file manager.
2. We find the directory "sdcard / Android / data / data", in it the files relating to this application. They will contain the name of the program in the name, so it will be quite easy to distinguish them from the rest.
3. We do the same in the "data / data" directory.

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

498

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

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

After that, the error should disappear.

923

1. Delete Google account and several unnecessary programs, clear the cache.
2. Clearing the system cache:
   1. We go into Recovery (the ON button and the volume control button and hold).
   2. Select Wipe Cache Partition.
   3. We reboot the device.
3. We reboot the device.
4. Log in to Google again.

403

There is a so-called Dalvik cache. In connection with its filling, we again do not want to install certain programs. To solve the problem, we clean the data and turn off Google Accounts first, 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 take actions, as with other similar errors.

1. Clear the cache and remove unnecessary unnecessary applications.
2. Erase data and stop Play Store and Google Services Framework.
3. As described in the previous error (403), delete the cache via Recovery.

492

The content from Google Play is not loading again.

1. We clean the data and stop the "Google Play Services".
2. We do the same with the Google Play Market.
3. Delete the dalvik cache if the problem is still present. However, this can only be done with root access.
4. If there are no root rights, then you just have to do a full rollback of the system.

911

It also doesn't allow you to download apps.

1. Clear data, cache, stop Google Play Market.
2. Try connecting to another WiFi networks or use mobile data to download the app.

Rpc:aec:0]

Problems getting data from the server. Deleting all synced accounts can help. Then we clear the cache and data of the Play Market, and then restart the smartphone or tablet.

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

927

This fault is independent of our device. The reason lies in the fact that the program is updated by developers. Therefore, if we want to install or update it, we cannot 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 as a last resort. This . A full reboot of the Android system will delete all user data, so the most important thing is to first transfer it to a memory card or save it in cloud services.

1. Open settings.
2. Select "Reset and Restore" different devices it can be called differently and can be located either in the settings menu itself, or in the “System” item.
3. We press "Reset".

After that, the device returns to the 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 services errors, which are so rare that there is no data about them yet or has already been fixed by developers.

A similar error can only appear if the user initially turned it on (on a tablet or other mobile device).

This function ensures the protection of personal data stored in the memory of the android device. Encryption in this case produced by the ICS system using a 128-bit master key. If a password or pin is set to unlock the screen, then Android by default selects it as the "source" for creating a decryption master key.

After enabling the encryption function, each time the OS is rebooted, the device will request the specified password or pin.

However, no system works without errors and periodically the android encryption fails here, which makes unforeseen changes to the 16 kilobyte master key.

Such a failure can “show up” at any time, so in order to ensure that you do not lose the necessary information, always keep backup copies of your data. To do this, for example, you can make a backup on a Google account.

Otherwise, the cost of decrypting the card will "come out" much more expensive than the cost of all the information stored in the phone's memory (which will need to be decrypted). In the worst case, decryption will take so much time that the information will lose its relevance long ago.

Android encryption error: what to do?

So, what to do if the phone writes "encryption failure"? Such a message appears before the graphical shell is loaded, for the reason that the module responsible for encryption (Cryptfs) is loaded one of the first. It allows all other modules to decrypt the settings, read data from the cache and load the full version of the OS.

1. 1. First, you need to remove from the device microSD card. Due to Google's policy, the information on it is not encrypted by default, and, accordingly, this data may still be available.

The worst thing you can do now is to press the only soft button on the screen - Reset phone.

After activating it (in most cases), you can say goodbye to the information stored in the / data folder and, possibly, / sdcard.

1. 2. After removing the card, try restarting your android device using the mentioned button. If you didn’t succeed in eliminating the encryption failure on the tablet the first time, try a few more times: perhaps the key is simply not loading correctly due to an error in the code located on the external card.

Unfortunately, in most cases, rebooting does not fix the encryption failure, since either the internal card of the android device or its controller are “knocked down”.

1. 3. If restarting the phone / tablet did not help fix the encryption failure, you should “roll back” the firmware and install new version cryptographic module: so that the device can be used.

This will require an external card, preferably at least 8 GB (you can use the “old” one if all important data has been backed up from it), on which the / data and / sdcard temporary partitions will be saved.

1. 4. Insert a microSD card into your android device.

The next step is preparing the phone for flashing. To do this, you need to enter the android recovery. Depending on the model and manufacturer of the device, access to this mode can be done in different ways, but the most common key combination is to simultaneously press the power and volume down buttons with fixation for one to two seconds.

In recovery mode, find the properties of the SD card and divide it into segments that will be reserved for the above sections. For the /data area, 2 GB of memory should be enough.

For "swap" select 0M. The process of preparing the map will take some time - during this time you can download latest version ICS corresponding to your phone/tablet model.

After downloading, save it to the already partitioned SD card.

At this point in recovery mode, the feature should be activated as an external media.

When the connection to the computer is secured, do not forget to make a full "backup" of the information stored on the android device.

This time, the device will take a little longer to start up, but after a reboot, the encryption failure will already be “cancelled” and work with the device and external card will continue as before.

You use your Android smartphone (tablet) to save personal photos, read important emails, make online purchases with your credit card, edit and transfer important documents? If your answer is yes, then you should consider encrypting your device.

Unlike iPhone, android devices do not automatically encrypt the data stored on them, even if you use a password to unlock the device, but if you are using Android Gingerbread 2.3.4 or higher, then encryption is easy to enable.

Encrypting your phone means that if the phone is locked, then the files are encrypted. Any files sent to and received from your phone will not be encrypted unless you use additional methods.

The only difference between an unencrypted and an encrypted phone from the user's point of view is that you will now have to use a password to unlock the phone (tablet).

If your phone is not encrypted, then the password is just a screen lock. In fact, in this case, the password simply locks the screen - that is, does nothing to protect the files that are stored on the device. So, if attackers find a way to bypass the lock screen, then they get full access to your files.

If the phone is encrypted, the password is the key that decrypts the encrypted files.

That is, when the phone is locked, all data is encrypted, and even if attackers find a way to bypass the lock screen, then all they find is encrypted data.

How to enable encryption on an Android device?

1. Open the Settings menu.

2. In Settings, select Security > Encryption (Encrypt device).

3. As required, you must enter a password of at least six characters, at least one of which is a number.

As soon as you set a password, the process of encrypting your files will start. Encryption can take an hour or more, so you must turn on the charger before encryption can begin.

Once the encryption process is complete, you're done! Make sure to save your password in a safe place, because now you will need it every time you want to access your phone. Please note that if you forget your password, there is currently no way to recover it.

In fact, encryption of Android devices, along with obvious advantages, also has significant disadvantages:

1. Imagine that every time you want to make a call, you need to type in a complex password. I wonder how soon you'll get tired of it?
2. You will not be able to decrypt an encrypted device, it is simply not provided. For decryption, there is only one way - to reset the phone to factory settings. In this case, of course, all your data will be lost. It will look especially interesting if you forget to make a backup beforehand.

Thus, today there is a difficult choice - either you encrypt your device and put up with huge inconvenience, or you get ease of use, but at the expense of security. Which path will you choose? I don't know. Which path would I choose? I can't answer either. I just do not know.

Vladimir BEZMALY , MVP Consumer Security, Microsoft Security Trusted Advisor

In pursuit of more and more data security on phones, software developers have decided to resort to the most cardinal method - encryption. But, as always, a lot of pitfalls and nuances have appeared, so you need to think three times before encrypting. What troubles can there be, what does this type of protection give, and what can you lose if Android encryption fails?

What is encryption and how does it work

User Action

If you encounter such a message and don't know what to do with an encryption error in Android, start by rebooting.

Just do not press the button under the inscription! You need to reboot the device by pulling the battery. If you have a non-removable battery, use the special button combinations for this action. Every self-respecting manufacturer is obliged to equip a device with a non-removable battery with such a combination - check this on the developers' websites.

We carry out such an operation several times: if the result is the same, then most likely you will lose absolutely all data from the device. It will not be so painful for owners of smartphones with the ability to expand memory with cards: Google does not encrypt data from them and you can remove the USB flash drive, saving the files.

To prevent any error in functions, you can simply not include them. If you are wondering how to remove encryption on Android, then there is good news: it is disabled by default if you do not own Google's Nexus line. There, the feature is enabled by default and can only be removed by flashing it.

In other cases, it is better not to enable encryption at all: the speed of work is reduced, all background activity is turned off (even the alarm clock is not set), and if you forget the password, say goodbye to the data.

Let's get back to the problem. If a hard reboot did not help, you need to try to do it programmatically, already with the flash drive removed.

Step by step instructions

To fix the encryption error in Android, press the restart button on the screen; you can't go wrong since she's the only one there. As in the case of the hardset, we do this several times to give the key a chance to boot correctly. If our efforts are in vain and nothing worked, you need to try to restore the device.

The first way (if you have USB debugging enabled). With the power and volume down keys held down (the key combination may vary depending on the brand and model of the phone or tablet), we connect the phone to the computer. It must have a running proprietary program. If you're lucky, it will be possible to easily restore the default settings.

The second way (if there is a recovery). When loading, we enter the standard CWM (methods vary, check for each developer), point using the navigation buttons in this menu(volume keys) to the item "wipe data / factory reset" and select it with the power button.

Then we agree to the deletion of all user data by clicking on "Yes - delete all user data" with the same key.

After that, you can reboot the restored device by selecting "reboot system now".

None of the methods helped.

We use the most cardinal method only in the most severe cases, when there is no debug mode enabled or when the device is not displayed. This is a device reset.

Firmware instructions

To flash the device, we need to download the desired firmware and upload it to a USB flash drive. Next, we repeat the entire second recovery method, only we also delete the “Cache” and “Dalvik” items.

It will be easier, more reliable and faster if you have a custom recovery with an unlocked bootloader.

What is "Forbidden by Encryption Policy"

This error may bother you if you still decide to disable the screen lock, but cannot do it. Its cause is most often conflicting applications with administrator rights.

In this case, you will need to remove the certificates and clear the credentials in the lock screen or security menu. You won't lose any content, and the admin error will disappear.

Android encryption failed: what to do?

On modern phones and tablets, we store a lot of important and even confidential information. These can be personal photos, correspondence, audio recordings, logins, passwords, details bank cards and other. Often, users do not think about ways to protect such data, until, for example, they lose their gadget. In the worst case, it falls into the hands of intruders who are happy to use your information for personal purposes. Sometimes that's the whole point of stealing a phone. How to protect personal data?

Encryption and its meaning

To protect data, the most common password for a screen lock is used, for example, a picture lock or a numeric password. But often this method is unreliable. If desired, such protection can be bypassed and then all your personal data will be in full view. A more efficient way is encryption. The user himself will not feel much difference directly, but if the gadget is lost, even if attackers can somehow bypass the lock password, they will not have access to your data. Such encryption is done quite simply:
Explay Fresh - make hard reset on a smartphone

"Settings"; "Security" and "Encryption".

After that, you will need to enter the code and wait for some time until all the data is encrypted, this can take quite a long time, especially if their volume is large. It happens that over time you can see the message Android encryption failed, what should I do in this case?
What to do if the tablet / smartphone does not turn on or freezes

Encryption failure: how to fix the problem?

In order to avoid such problems, you should always make a backup copy of your data. For example, the Google cloud can become a reliable storage, this is the best option for all Android users. If you didn’t do this and saw a message about encryption failure, the main thing is not to rush to press the “Reset phone” button.

Pull out first external card memory, the data on it is not encrypted, this is provided for by the policy of the OS developers. Only after that you can click this button, but be prepared for the fact that you may lose personal data.

Only in rare cases, after rebooting the system, the failure is eliminated, in other cases, it will be necessary to roll back to the time until the failure was detected.

Be careful about data encryption so that you yourself do not become a victim of your vigilance.
