To protect data, Android has a function to protect the device with a digital or visual password (password-schedule or pattern). Thanks to the efforts of engineers, bypassing the security system is not so easy, scammers or thieves will not be able to unlock the phone or tablet. But what to do if it is you, the legal owner of the android device, who forgot a digital combination or a linear drawing?

What is a password graph on android

On Android, in addition to the usual sequence of numbers, you can also set a password-schedule.

A square of nine dots (3×3) appears on the screen. The user must connect them with a line in a certain sequence, without lifting his finger from the screen.

A graphic password is an unbreakable line connecting certain points in a predetermined sequence.

In other words, a graphic password is a sequence of connecting dots. For example, the letter Z, a star, just some kind of line.

Graphic passwords enjoy on Android more popular than digital ones, because a linear drawing is easier to remember than a four-digit number. However, you can forget any, even the simplest, password.

How can you protect yourself from blocking your device?

How to prevent your phone or tablet from being locked

The Play Market has a program SMS Bypass, the essence of which is as follows: if the password is forgotten, the device can be unlocked by sending an SMS with a specific text from another phone to yours. When the message is received, the system will reboot and again prompt you to enter the password. Draw any line and the smartphone will unlock.

Such a program, of course, requires root access. Initially it is "1234 reset". It can be changed to any other, at your discretion.

SMS Bypass can be set via personal computer after you forgot your password. But this requires root access (no wonder they say that root is insecure) or a Google Account.

What to do if you forgot your graphic password

There are several working methods that allow you to bypass protection and unlock your phone. Some will only work on certain versions of Android, others just work every other time. If one method doesn't work for you, try the next.

Login to Google Account

After 5–6 failed attempts choose a pattern password smartphone will prompt you to wait 30 seconds. At the same time, the button “Forgot graph. password?". Click on it. You will be asked to sign in to your Google account (the one your phone or tablet is linked to). If the data is entered correctly, the password will be reset.

To reset your password, sign in to your Google account

There is one caveat: if Android is blocked at the moment when it was not connected to the Internet, then it will not enter Google Account. In this case, you need to restart the device and drag the information bar down as soon as it appears. Then enter your account information as described above.

If you cannot turn on the Internet using the previous method, try using service codes.

  1. To do this, click "Emergency Call" and enter the following character set: *#*#7378423#*#*.
  2. In the menu that appears, intended for service center specialists, open Service Tests -> WLAN.
  3. Turn on Wi-Fi.

Alas, with the help of service codes it is impossible to enable a mobile connection. However, you can try to remove and insert the SIM card again, it is possible that the phone will connect to the network on its own.

You can also try connecting a SIM card from another operator (megaphone, mts, beeline, etc.), sometimes it helps.

If you cannot activate the network, buy a microUSB to LAN adapter used to connect fiber optic cables. Connect it to your smartphone and router. After a while, the Internet will appear on the device.

Call a smartphone

The method will help only on Android OS versions 2.2 and below, then there were no such sophisticated security systems.

  1. Call a blocked phone from any other.
  2. Answer the call without delay.
  3. Minimize the program and open "Settings", then "Security" and disable the passcode.

Dial the number

Even if the phone is locked, you can use it to call emergency services. In Android before version 5, there is such a feature: if you open the field for calling emergency services, and then press the "Back" button, then the Android screen will appear for half a second. You can use this moment to download the No Lock program and run it. The phone will be unlocked.

Discharge phone

You can try to wait. At that moment, when the charge is almost completely empty, Android will show you a corresponding message and offer you to look at the battery status. And the battery status is one of the sections of the "Settings" menu. So go to it, click on the arrow in the upper left corner of the screen, click on "Security" and cancel the password.

Delete files storing visual password data

The method is suitable for those who have a custom Recovery menu (CWM or TWRP) installed on Android. The essence of the method is to throw off the saved data about the graphic sequence, which is stored in the following files:

  • gesture.key;
  • locksettings.db
  • locksettings.db-wal;
  • locksettings.db-shm.

Via CWM

  1. Download any file manager for Android from your computer and put it on a memory card.
  2. Now turn on the Recovery Mod on the device (turn off the smartphone, and then hold down the "Home" button and the on / off button and hold for ten seconds until the manufacturer's logo appears).
  3. Using Recovery, install the file manager and launch it.
  4. Now open the /data/system/ folder
  5. Delete all the above files.
  6. Reboot the device and enter any pattern password. The smartphone will be unlocked.

Through TWRP

If TWRP is installed on the device as Recovery, then you can not download the file manager, since it is already embedded in the application.

  1. Enable Recovery Mod and open Advanced -> File Manager menu and then /data/system/ folder
  2. Delete the above files.
  3. Reboot the device and enter any pattern password.

With an additional user

If there are several users on the device, there is root access and you use the SuperSU program, then you can try to delete these files through an additional user.

In order to unlock the phone through an additional user, the SuperSU program must be installed

  1. Log in through the second user and install some file manager from the Play Market.
  2. Open it and go to /data/system/ folder
  3. Delete files:
    • gesture.key;
    • locksettings.db
    • locksettings.db-wal;
    • locksettings.db-shm.
  4. Reboot your device and while entering the password, draw any line you want. Android is unlocked.

Unlock with ADB RUN

ADB RUN uses a console of ADB drivers that connect the mobile device to the computer. The program is convenient because it automates the process of working with the console. Especially for cases when a person forgets the password, there is the Unlock Gesture Key function.

Unlock Gesture Key translates as "unlock the graphic key."


Reset to factory settings

The most rude and clumsy way. But efficient. It is suitable for any android versions and for all devices. But keep in mind that this will erase all information from the hard drive, and it will be impossible to restore it.

So, if you are desperate to bypass the lock in other ways, do a Hard Reset.

Hard Reset is a term that refers to resetting all settings to factory settings and deleting all data.


Contact Support

You can contact technical support directly from Android or the device manufacturer. They will ask you to provide them with a receipt and other documents for a smartphone or tablet to confirm that you are the owner. After that, you will be told what to do next. You may have to go to the service center, but they will definitely help you.

How to set a new picture password

Let's say you reset your pattern password. Now let's talk about how to install a new one.


How to disable pattern password

To reset your password, open Settings -> Security -> Lock Password. Locate the "Enable lock password" toggle and slide it to the "Off" position. To confirm the action, you will have to enter the current picture password.

Is it possible to bypass the digital password

The digital password can be bypassed in the same way as the graphic one. Almost all of the above methods will help to remove it. But there are some differences. For example, the gesture.key file is responsible only for the visual key, so you cannot remove the numeric key in this way. But it works great connecting to a Google Account, resetting settings and contacting support.

It's okay if you can't remember your password, no. It happens to everyone. Android developers took care of users and allowed them to reset passwords using a Google account, to which they still have to link their device. Although there is one significant problem: thanks to the abundance of methods, it will not be difficult for a thief to unlock a stolen phone or tablet. So it is better not to rely especially on this protection and do not keep secret data in your smartphone.

Modern phones and tablets based on Android, iOS, Windows Mobile have the ability to block them from strangers. To unlock, you will need to enter a PIN code, pattern, password, or put your finger on the fingerprint scanner (only relevant for new models). The unlock option is selected by the user in advance.

phone manufacturer and operating system provided the ability to recover the password / graphic key from the device without losing personal data on it. True, on some models, the process of restoring access is more difficult than on others due to design and / or software features.

Method 1: Use a special link on the lock screen

In certain versions of the Android OS or its modification from the manufacturer, there is a special text link by type "Restore access" or "I forgot my password/pattern". Such a link / button does not appear on all devices, but if it is, then you can use it.

However, it is worth remembering that in order to recover, you will need access to the email account to which the account is registered in (if we are talking about an Android phone). This account is created during registration, which occurs during the first inclusion of the smartphone. At the same time, an existing Google account can be used. This e-mail box should receive instructions from the manufacturer to unlock the device.

The instruction in this case will look like this:

Method 2: Contacting the manufacturer's technical support

This method is somewhat similar to the previous one, but unlike it, you can use a different email to contact technical support. This method is also applicable in cases where you do not have a special button / link on the device's lock screen, which is necessary to restore access.

Communication instructions technical support looks like this (considered on the example of the manufacturer Samsung):


Method 3: Using special utilities

In this case, you will need a computer and a USB phone adapter, which usually comes with a charger. Besides, this way Suitable for almost all smartphones with rare exceptions.

The instruction will be considered using the example of ADB Run:


Method 4: Deleting user settings

This method is universal and suitable for all models of phones and tablets (running on Android). However, there is a significant drawback - when resetting to factory settings in 90% of cases, all your personal data on the phone is deleted, so it is better to use the method only in the most extreme cases. Most of the data is unrecoverable, the other part you will have to restore for a long time.

Step-by-step instructions for most devices are as follows:

It is quite possible to remove the password that is on the phone on your own. However, if you are not sure that you can cope with this task without damaging the data on the device, then it is better to contact a specialized service center for help, where they will reset your password for a small fee without damaging anything on the phone.

We will consider in detail all these methods and designate unlocking schemes for phones from various manufacturers.

Unlock via Samsung Account

It's nice to know that some manufacturers take care of the users of their devices by offering additional services. A typical example is Samsung, which created the Samsung Account service. It contains functions for remotely erasing information from Samsung smartphones and tablets, functions for remotely blocking devices, as well as functions for searching for them. That is, if the lost device is not found, all important and confidential data can be easily deleted via the Internet.

How to unlock a Samsung phone if the password was safely forgotten? To do this, use the "Find my phone" function with its sub-function "Unlock my device". It allows you to restore the health of your smartphone or tablet by resetting the screen lock settings. To do this, you need to go to the official website of the service, select the "Find phone" item, make sure that there is a connection with the device and click on the "Unlock my device" button. After that, a command to reset the lock parameters will be sent to the smartphone / tablet.

In order to use this functionality, you need to pre-lock your phone / tablet by allowing remote control via Samsung Account in the security settings. In addition, the locked device must be connected to the Internet.

Unlock password via Google account

The developers of the Android operating system have taken care to facilitate the restoration of access to smartphones and tablets in case of a password loss. For this, a link to a Google account is provided. It is she who will help us in the matter of restoring access to the content and functionality of the Android device. How to unlock phone with google account? Incorrect password entry leads to the fact that the phone is blocked for a while. That is, we are given time to remember the ill-fated password.

Also, temporary blocking allows you to stop attempts to guess the password by intruders. After five attempts to enter the password incorrectly, the phone will prompt us to enter the password from our Google account. We remember the password, enter it in the field that opens - the lock is removed! Now you need to go to the security settings and reset the password, since we could not remember it.

From this we can conclude that in order to successfully restore access to your device, you need to know and remember the password from your Google account - write it down and save it in a safe place. This place could be your phone box.

Unlock with additional PIN

Let's get back to unlocking Samsung phones, since we haven't discussed another way to restore access - using an additional PIN. It is assigned when setting the main security password and includes four digits. Here you need to enter numbers that you will definitely never forget. If you have forgotten the main password, allow several attempts to enter incorrectly, after which you will have access to the PIN code entry form - enter the cherished numbers and restore access to your phone.

Do not enter too light number combinations as a PIN code - this can help intruders gain access to the data stored on your phone. Enter here, for example, the PIN code of your credit card that only you know.

Unlock via master reset

How to unlock the password on the phone if all the above methods do not work? You can use very simple solution– perform a factory reset. The disadvantage of the method is that all the data from internal memory will be completely removed(only the contents of the memory card will remain).

How to perform a master reset if menu access is blocked? To do this, you need to enter Recovery Mode - this is done using combinations of buttons held down when the phone is turned on. What combinations might these be?

  • Both volume buttons and power button;
  • Volume up button, home button and power button;
  • Volume down button, home button and power button.

There are also many other button combinations that allow you to put your phone into Recovery Mode - look for the appropriate instructions on our website or on specialized forums. Entering the Recovery Mode, you need to find and select the item "wipe data / factory reset". After confirming your intentions, you will start the reboot process with resetting the device to factory settings. At the same time, the previously set password will be deleted..

If you don't want to lose important data, make it a habit to regularly create and save backups your files. Cloud services are also used for this.

Unlock phone through flashing

This method is one of the most cardinal, as it allows you to completely replace the software in your phone. At the same time, interfering blocking is removed. How to unlock phone through flashing? To do this, you need to figure out how your phone is being flashed - we are looking for suitable instructions, downloading firmware files and programs, and charging the battery. After that, we connect the phone to the computer, run the software, select the firmware files, perform other operations provided for by the instructions. We start flashing and wait for the completion of the procedure - then we enjoy the lack of blocking.

Flashing phones is carried out using a special software, which is selected depending on the manufacturer of the handset and its model. For example, the Odin program is used to flash phones from Samsung - here the owners of handsets from the South Korean giant are very lucky, since the program is very easy, and even an inexperienced user can handle the flashing procedure.

Fly and Sony phones are flashed with the Flashtool application - it is quite easy, but it will not hurt to re-read the instructions once again. Chinese phones running on MTK processors (and other handsets with these processors, for example, from MegaFon or Beeline) are flashed using the SP Flash Tool program. There is nothing complicated in it, therefore, in most cases, the flashing is successful - you just need to blindly follow the instructions, and not experiment, playing with the program parameters.

Remember that flashing the phone, like resetting to factory settings, involves the complete loss of data stored in the internal memory.

Unlock phone through security holes

This method is relevant for owners of very old handsets, where it is very easy to bypass protection by fraudulent means. A typical example is bypassing a lock using the usual phone call. The protection goes as follows - we call a blocked phone from another phone, we accept a call, in the process of making a call we go to the settings and turn off the password request. Next, we drop the call and enjoy the unlocked phone.

This security hole is present on smartphones running Android 2.2 and below..

This is not the case in modern phones, so you can’t really rely on this method - but the owners of old handsets will be incredibly happy with this method of disabling the lock.

Another hole is covered in the process of discharging the battery. At a certain stage, the system will notify you of a strong discharge and the need to connect charger. At this point, we can click on the link to show battery usage statistics. From here we will go to the settings and turn off the password request. Naturally, this method does not work in modern phones, so you can not count on it - better check out other methods that are more effective and efficient.

Unlock phone via SMS Bypass

Have you rooted your phone and are enjoying features not available to other users? In this case, you need to take care that you can forget the password - let's try to create a workaround. To do this, we will use the extremely useful SMS Bypass application. We download it, install it on the phone, go to the settings and set the digital code - it will serve as the key to unlocking the handset.

How to unlock your phone with SMS Bypass? To do this, you need to send an SMS to your number with the text “XXXX reset” - instead of XXX, enter the previously indicated digital code. After receiving the SMS, the phone will go to reboot, after which it will prompt you to enter the password again- enter arbitrary numbers and get at your disposal an unlocked handset.

To obtain root rights, use the instructions on our website or look for a more suitable solution on specialized resources and forums.

Unlock phone through codes

Forgot your password and can't use your phone's features? We have already said that password reset is performed by resetting to factory settings - this is done using the Recovery Mode. But what if the phone does not have this mode? Then we try another solution - if when entering a password it is possible to select a keyboard for dialing, you should dial on it the general reset code or the exit code to the engineering menu. Find the appropriate codes on specialized forums and try to use them to unlock your phone.

Do not enter commands whose purpose you do not know - such actions can lead to the most unpredictable consequences, up to the complete loss of the phone's performance.

Unlocking Your Phone with Aroma Manager

Are you an advanced user and do you have root access and custom CWM recovery on your phone? Then you can unlock the handset in one of the most advanced ways. To do this, you need the Aroma file manager, which should be downloaded to a memory card. Next, turn off the phone and turn it on with a transition to CWM, install the application, go to the system folder / data / system and delete four files there - locksettings.db-shm, locksettings.db-wal, locksetting.db and gesture.key. These files store data about the set passwords and graphic keys..

This unlocking method is available only on prepared phones and only for trained users. To obtain superuser rights and install custom recovery, use the appropriate instructions. Do not perform actions and do not run programs whose purpose you do not know - this way you will save your phone from the "brick" state.

PIN unlock

How to unlock your phone if you forgot your PIN? You have three attempts to enter the correct PIN code. If all attempts have been exhausted, the phone will prompt you to enter the PUK code - you can find it in the connection kit or request it via help desk your operator by calling hotline. After entering the correct PUK code, the phone will unlock and prompt you to assign a new PIN code - keep it in a safe place.

You have ten attempts to enter the PUK code. If all attempts were wrong, the SIM-card will be permanently blocked - you will have to get a duplicate in the nearest communication store. No other available ways unlock the phone when the PIN code is forgotten.

Unlock phones on Windows Phone

If your phone is on Windows phone, you can unlock it through the site of this operating system. By logging in with your username and password, you will find in personal account linked phone and you can unlock it. This unlock method works on Lumia handsets and handsets from other manufacturers. Another way to unlock your phone on Windows Phone is to perform a factory reset (useful if you don't remember your username and password).

To reset, press the power and volume down buttons until they vibrate. Release all buttons and press the volume down button again until an exclamation mark appears on the display. Now successively press the volume up, volume down, power and volume down buttons again - after a while the phone will reset.

Please note that this procedure involves the complete removal of all data stored in the phone - do not forget to make backup copies.

Ways to unlock phones by brand

How to unlock a Samsung phone if you forgot your password? To restore prepared handsets, you can use the Samsung Account service. If you haven't prepared your phone for remote control, try sneaking into Recovery Mode and doing a reset. The last technique will be flashing the phone through Odin.

In order to unlock the phone from MTS, you can use a general reset or flashing. If your handset has root and CWM, try installing Aroma and deleting the files responsible for blocking. Many other phones are unlocked in the same way, for example, from ZTE, Lenovo or Fly. And to unlock your Nokia phone, you can use the MyNokiaTool application (for PC).

In order to unlock your LG phone, you should use flashing, master reset or custom recovery with the Aroma file manager. In addition, some LG smartphones are assigned an additional PIN code that will help you unlock your phone when forgotten password. A similar function is available in many modern smartphones from Samsung.

The most universal way to unlock is to use a Google account - try to learn the account password or save it in some safe place. If none of the above helps, contact the nearest service center.
