The most basic way to protect an Android smartphone is the screen lock function. Currently, fingerprint or face scanning is widely used to unlock the device, but older devices use a password or pattern that can be forgotten, thereby losing access to the smartphone. In this article we will tell you how to do complete shutdown blocking in this case.
Screen lock - settings and methods
First, let's figure out how to enable screen locking. To do this, you need to go to the settings of your smartphone and find the “Security” item there, in the menu that opens, go to the “Screen Lock” tab and select the method that suits you. Typically, on smartphones without a fingerprint scanner, a password or pattern is used. When you turn on the latter, you need to draw a sequence between the dots with your finger, which you will need to enter every time you unlock your smartphone. 
To remove the screen lock, perform the same steps in reverse order. Go to settings, get to the desired menu item and select “Disable screen lock”. The system will ask you to confirm the action by re-entering your password or pattern. But what if you forgot them?
How to remove the lock from your phone screen if you forgot your password
The most convenient and quick way in this case, it is to use personal Google account. If you remember email, to which the smartphone is linked, and the password to it, enter the wrong one graphic code the maximum possible number of times, after which the smartphone will be locked and the message “Forgot your password?” will appear on the screen. Click on it and to restore access to the phone, enter your e-mail and password to your account. 
The above method can only be used if the Internet is available to enable Wi-Fi on a locked smartphone in the menu emergency call dial *#*#7378423#*#* and in the window that appears, click “service tests - wlan”, then: “connect to wi fi network”.
If you have forgotten the password for this account, you will need to use a more drastic method - resetting your smartphone to factory settings via recovery. If you follow the instructions, there is nothing complicated about this even for inexperienced users. When you reset the settings, in addition to the password, all information from the smartphone’s memory will be erased: calls, contacts, messages, programs and files, only the contents of the SD card will remain untouched.
To restore the phone to factory settings if you do not have access to the interface, you must enter the “Recovery” mode. This is done differently in devices from each manufacturer, so explore the Internet for access to Recovery specifically for your smartphone model. Once in the menu, find and activate the “Factory Reset” item there. 
To avoid losing the most important information such as contacts in the future if a similar problem occurs, synchronize them with your Google account, which will allow you to restore them if necessary. phone book. The same can be done with photographs; this opportunity is provided by the Google Photo service, which itself can upload all the photos you take to the cloud automatically.
We delete a graphic key without losing information
There is a way to remove the pattern via Recovery without reverting the phone to factory settings. 
To do this, you need to put your phone into recovery mode and open the “Advanced” tab. 
Then go to " File Manager"and in the /data/system folder, delete the files responsible for displaying the graphic key:
To do this, hold down the file, select “Delete” in the context list and confirm the action by swiping to the right. 
Then click “Back” and perform a similar operation with all the above files. 
Often, users of mobile gadgets running on the Android OS are faced with the problem of disabling the screen lock. A pattern, password or PIN code has been set, but the owner of the device wants the protection to be removed with a simple movement of a finger, or the screen not to be blocked at all. Trying to simply go to the menu and remove restrictions, the user sees that he cannot access the necessary options, since the necessary lines are inactive. This error has a fairly simple solution, and now I will tell you what needs to be done to remove restrictions if these actions are prohibited by the administrator, encryption policy, or credential store.
Settings menu with error message "Prohibited by administrator, encryption policy, or credential storage service"
Why does the administrator ban error occur?
In addition to the fact that mobile gadgets on the Android platform have built-in programs that ensure data security, many users install additional funds protection and, without knowing it, trigger the administration or encryption policy. As a result, the owner of the device turns on such protection that he himself does not have access to certain settings of the tablet or phone.
Also, the error message “Forbidden by the administrator, encryption policy, or credential store” may pop up when installing any useful software that has a certificate that changes the settings mobile device. In this case, the application requests permission to activate the device administrator, and if the user confirms the action, after installation is complete, a message pops up stating that the administrator has been activated.
Administrator activated
The third reason is corporate security policy. That is, if using your device you access information from your employing organization, and your email account is remotely connected to the company network, the error may be caused by the actions of IT specialists. In this case, before solving the problem, you should contact them and together try to eliminate the “Forbidden by the administrator, encryption policy, or credential store” error.
How to fix the “Forbidden by administrator, encryption policy, or credential store” error
If the problem arose after installing an application that provides additional protection for the device, then if this program is not needed, it must be removed. If you do not want to delete the application, you can disable the administrator so that no third-party programs can control your phone. To do this, in the gadget settings you need to go to the security menu and go to the “Device Administrators” item.
Device Administrators
If there are any programs in this menu, especially ones that are unknown to you, you need to click on their name. If a message pops up stating that the administrator is activated and allows the application to lock the screen, this means that these rights must be removed from this program - uncheck the box or move the button. If necessary, you can go back to this menu and again give the application the right to block the screen.
Programs located in the "Device Administrators" menu
The next step is to clear the device certificates that do not allow you to reduce the security level of the device. The required item is located at the very bottom of the “Device Administration” menu. Depending on the gadget, it is called “Clear credentials” or “Clear certificates.” In both cases, the same action is assumed - deleting all certificates. Select it and confirm the action.
Cleaning up certificates
If you are afraid that you will lose personal data in the process of deleting certificates, create them backup copy. You can send important files to the cloud, and then download them again to your phone. Nothing bad will happen to the device itself. A big plus of the Android OS is synchronization with a Google account. In this case, all contacts are stored on the cloud by default. If in doubt, check the synchronization. To do this, in the settings, go to the “Accounts” or “ Accounts” and click on Google. There you will see all the necessary information.
Google account
For normal operation, restart your smartphone or tablet, go to the security menu again and check whether the lines that previously contained the error message “Forbidden by the administrator, encryption policy, or credential storage” have become active. If yes, then feel free to disable the screen lock or activate simple finger unlocking.
This method should give desired result– unlock inactive fields. If this does not happen, then the last option is to reset to factory settings. Before performing these actions, save important information: personal photos, videos, files necessary for work, since all data will be lost when resetting.

Screen lock prevents accidental clicks and protects the contents of your device from strangers. However, some users are so annoyed by the need to constantly unlock their phone that they begin to look for a way to get rid of this function.
You can remove the blocking using basic system configuration tools. But it would be safer not to abandon the screen lock altogether, but simply choose a more convenient way.
Unblocking
If the lock is removed by entering a password, PIN code or pattern, and you know it, then there will be no problems - just go to the settings and remove this method of data protection.
I have a PIN code, but with the fingerprint scanner enabled and configured, entering a four-digit password is only an additional verification method. The screen is unlocked using a fingerprint. To completely remove the screen lock, select the option " No" This will remove the unlock password and added fingerprints from the phone if the device has a scanner.
« No" - is not the best option in terms of ease of use. If we are talking about a phone that you constantly carry with you, then completely disabling the lock can result in accidental clicks. Launching applications, sending messages, outgoing calls are companions of an unlocked phone screen.
To prevent accidental clicks, but not to enter any passwords or unlock keys, select the " Swipe" In this case, the password and fingerprints will also be deleted, which means you will remove protection from the phone. The screen will lock after a set period of inactivity, but you can unlock it with a horizontal or vertical swipe.
Selecting a blocking method
Since we started talking about blocking methods, let's look at everything. For example, I am annoyed by entering a pattern and PIN code. Therefore, on the old smartphone the lock was unprotected and was removed with a horizontal swipe, while on the new one it was unlocked using a fingerprint. You might like another way.
There are these options:
- « No» – the screen is not blocked. Cons: accidental clicks are possible, there is no protection from strangers, that is, anyone can take your phone and study the contents of its memory.
- « Swipe» – the display is blocked. Disadvantage: no security, anyone can unlock it.
- « Graphic key», « PIN code», « Password" Some devices add face and voice recognition, but this does not change the essence: when choosing any of these methods, the screen is locked, and only the owner can access the contents of the phone.
If your phone has a fingerprint scanner, you can add fingerprints to settings, choose from three secure screen lock methods, and choose how to unlock your device. As I already said, I have to enter a PIN code or verify a fingerprint. You can set a combination of a pattern key and fingerprint scanning - also convenient. Experiment, you may lose the desire to give up blocking altogether.
What to do if you forgot your password, code or pattern
We've looked at the ideal situation where you have all your passwords, PINs and graphic keys. But how to remove the protection if the screen is locked and you don’t remember the password or key? Methods may vary depending on the manufacturer and model, so we will briefly go over the most popular methods.
I only recently learned about the latter method. The service is available at
