It is important to understand that the menu interface may differ slightly depending on the firmware version installed on your Galaxy A12.
Regular disabling of blocking through settings
The easiest and safest way to remove a graphic pattern is to use the standard smartphone settings menu. This method is only suitable if you have access to your desktop and remember your current unlock code. Before making changes, the system will require you to confirm your identity, which is a standard procedure user verification.

Reset via Google account and the “Find My Device” function
In situations where the user has forgotten the pattern key, but the device is logged into the account Google and there is an Internet connection, you can use remote control. The Find My Device service allows you not only to track your location, but also to execute commands to clear or change access settings, although modern versions of Android have limited the ability to simply change the password remotely.
First, you need to go from any other device (computer or tablet) to the official website of the Google Find My Device service. Log in using the same mailbox that was used on the blocked Samsung A12. If the smartphone is online, you will see it on the map and a list of available actions in the side menu.

This is an extreme measure, but the only guaranteed way to regain access to the phone without knowing the code, unless a specific bypass has been configured.
Why doesn't remote unlocking work?
In older versions of Android (before 5.0), it was possible to change the password remotely. In modern versions of One UI and Android 10/11/12/13, Google has strengthened protection, leaving only a hard reset function to prevent data theft.
Resetting settings via Recovery Mode (Hard Reset)

☑️ Preparing for Hard Reset
Comparison of unlocking methods and their consequences
The choice of how to disable the pattern depends on your specific situation: do you remember the password, do you have access to the Internet and how important is data safety. Below is a comparative table that will help you decide on the optimal method of action for your model Samsung.
| Method | Data safety | Menu access required | Complexity |
|---|---|---|---|
| Via Settings | Full | Yes | Low |
| Smart Lock | Full | Yes (for customization) | Low |
| Find My Device | No (delete) | No (internet required) | Medium |
| Recovery Mode | No (delete) | No | High |
As can be seen from the table, regular shutdown through settings is the only method that saves user information. All other methods related to restoring access when a password is forgotten lead to clearing the memory. Therefore, regular backups to a cloud service Samsung Cloud or Google Drive remains critical.
It is also worth noting that on some models with new generation chips, the procedure for logging into Recovery may differ. For example, on devices with Android 11 and higher without a connection to a PC, the button combination may not work. In this case, you need to use the app Odin or official service centers for flashing.
The only way to save data if you forget your password is pre-configured synchronization or using Smart Lock before blocking.
Frequently asked questions (FAQ)
Is it possible to disable the pattern lock without knowing it, but saving the data?
Unfortunately, on modern versions of Android with encryption enabled, this is almost impossible. The system stores an encryption key tied to your password. Without entering the correct pattern, the data remains encrypted and inaccessible. The only exception is if USB debugging mode was enabled and special rights were set, but this is rare for ordinary users.
What should you do if after a reset the phone says “Account not found”?
This is a Google servers error or a timing problem. Try setting the correct date and time in the settings (if you have access) or wait 24 hours. Also make sure that the SIM card with the Internet is active, since a connection to the authorization server is required to verify the password.
Does removing the screen lock affect the Samsung warranty?
No, changing security settings, including disabling the pattern through the standard menu, is the right of the device owner and does not violate warranty obligations. However, if you used third-party hacking software (root access), the warranty may be void.
How often do you need to change the pattern key on the Samsung A12?
Information security specialists recommend changing passwords and access keys every 3-6 months. This reduces the risk that a smudge attack will allow an attacker to restore your line combination.
Is it possible to use a fingerprint instead of a key?
Yes, this is a more convenient and secure option. You can set up biometrics in the menu Biometrics and security. However, after rebooting the phone or after 72 hours, the system will still require you to enter a pattern key or PIN code, since biometric data is stored in a secure module and requires initial activation with the main password.
