Xiaomi Redmi series smartphones are famous for their functionality, but sometimes users are faced with the need to change the security settings. Owners of the Redmi 9T model often look for ways to disable the pattern lock to make it easier to unlock the device or replace it with a more reliable pin code. This action may be necessary if the current pattern has become too complex for daily use or, conversely, too simple to provide proper protection.
The process of deactivating the screen protection in the shell of MIUI (or HyperOS) has its own features that distinguish it from standard Android. It is important to understand that to perform this operation you will need access to the current security settings. If you forget your key, the procedure will be radically different and require a data reset, but in this guide we will look at the standard method through the settings menu that saves all your photos and applications.
Before you start changing your settings, make sure your Redmi 9T has at least 30-40% battery power. Although the process does not require large amounts of energy, suddenly turning off the screen during the reconfiguration of system security files can lead to software errors.
Preparation for changes in safety parameters
The first step before disabling protection is to check the current lock status. MIUI-based Android requires the user to log in before making changes to critical sections.This means you will need to enter the current graphical pattern or digital code that is currently installed. Without this step, the settings menu will not be available for editing.
You should also pay attention to tied accounts. Modern versions of Xiaomi firmware have a mechanism for protection against theft. If the Find Device feature is activated on the phone, when you reset or change key security settings, the system may require you to re-enter the password from Mi Cloud or Google Account. Make sure you remember this data so that you do not get a locked device after trying to turn off the protection.
⚠️ Warning: If you plan to remove your screen lock completely, remember that this makes your phone vulnerable to unauthorized persons in the event of a loss.Consider alternatives such as fingerprint unlock or facial recognition that combine convenience and security.
Check for important system updates before you start manipulating. Sometimes lock screen bugs are fixed in new versions of MIUI. Go to the updates section and make sure your software is up to date. This will help you avoid situations where the settings are not saved due to software errors.
Step-by-step instruction to disable the key through settings
The main way to access control is through the main settings menu. Xiaomi's interface may vary slightly depending on the firmware version, but the logic remains the same. You need to find the section responsible for passwords and security, usually located at the top of the list or in the category "System applications and settings".
Once you log in, you'll need to go through a few layers of nesting, and you'll first select the type of protection you want to remove, and you'll have a few options: Lock screen, Privacy, Application Protection, and we're interested in the lock screen, because it controls access to the device itself.
☑️ Algorithm of action
When you go to selecting the unlock method, the system will require you to confirm your authority. Enter the current graphics. Only after successful verification will a menu open where you can select the option "Disable" and clicking on this button will result in complete deprotection, and the next time you turn on the screen, the phone will immediately go to the desktop.
In some cases, especially on corporate devices or when using certain security profiles, the administrator may prevent disabling the lock.If the "Disable" button is inactive or hidden, check if enterprise security policies or special access modes are enabled.
Replacement of the pattern lock with other methods
Often, users want to not just leave the phone unprotected, but replace the complex pattern with a more convenient method. Redmi 9T features a fingerprint scanner built into the side button on, one of the fastest and most reliable ways to unlock, which is much more convenient than constantly entering a password.
To set up the biometrics, go to the same Passwords and Security menu and select Unlock by fingerprint. The system will ask you to put your finger several times to create a digital cast, and then you can set the "Unlock in Sleep" option, which allows you to open the phone with a simple touch without pressing the on button.
Another popular method is Face ID, which is less secure than a print because it uses a conventional front-facing camera, but for many users, it's the fastest option, but it's worth remembering that in total darkness, this method may not work properly without additional screen lighting.
Comparison of safety techniques
When setting up a new method, the system will suggest creating a backup PIN-Never ignore this step, as biometric sensors may fail or stop working when the device is restarted, and password login will remain the only way to get into the system.
Working with application passwords and second space
In Xiaomi's ecosystem, there's this concept of "Second Space" and "Hidden Profile," which are separate, isolated environments that can have their own graphical keys, different from the main one, and if you're trying to remove the security, but it comes back or appears elsewhere, maybe these are the features that are being addressed.
To control access to the Second Space, you need to use a special switch at the top of the settings screen or through the Security app, where you can set a separate password or disable the login by going back to the main profile, and it is important not to confuse the keys, since they are independent of each other.
There's also an app protection feature, which allows you to put an additional pattern lock to run specific programs, such as WhatsApp, Gallery or bank clients, which is located in the app Security -> Application Protection. Disabling the main key of the screen does not remove protection from individual applications if it was configured separately.
| Type of protection | Wherever | Impact on data | Difficulty shutting down |
|---|---|---|---|
| Lock screen | Settings -> Passwords and security | It doesn't. | Low. |
| Application protection | Security Annex | It doesn't. | Low. |
| Second space | Settings -> Second Space | Removal of space | Medium |
| Encryption SD-map | Settings -> Storage | Requires formatting | Tall. |
If you are faced with a situation where the phone requires the Mi Account key after trying to reset or change the security settings, this means that the theft protection has been activated, in which case without entering the correct account information to which the phone was previously associated, you will not be able to access the system even after completely flashing.
Possible problems and ways to solve them
Sometimes users are faced with the fact that after disabling the key, it is requested again the next time you restart, this can be caused by a cache error or a conflict of programs, in such cases, it is recommended to clear the Settings and Security cache of the application through the application management menu, saving important data beforehand.
Another common problem is the sticking of the input, and the screen may not respond to touches in certain areas, making it impossible to enter a complex graphic pattern to turn it off. USB-mouse-adapter OTG port of Redmi 9T. This will allow you to accurately select the right points on the screen and successfully pass authorization.
⚠️ Attention: Using third-party unblocking software (called "breakers") on modern versions of Android often results in complete data loss or bootloader lock.Standard methods through settings are the only safe way to go.
If the system writes "Incorrect Password" when entering the correct key, it may have changed the input language or keyboard layout in the system settings before locking. Try entering the key by closely monitoring the indicators on the screen, or restart the device to reset temporary interface errors.
💡
If the screen sensor is not working properly and interferes with key input, try using the gaze control or voice control function if they were pre-configured to get to the settings menu.
The Impact of Mi and Google Accounts on Unblocking
Security in Xiaomi is closely integrated with cloud services. When you turn off the pattern lock, the system can silently update access tokens. If you decide to reset your phone through Recovery Mode because of a forgotten key, Mi and Google accounts will be the main obstacle. FRP (Factory Reset Protection protects the device from unauthorized use.
It is important for Redmi 9T owners to understand the difference between a local password and a cloud one. Local is stored in a secure area of CPU memory, and cloud syncs the status of trusted devices. If you changed your password from a Google account recently, the phone may need to confirm it when trying to change your security settings, even if the local key is entered correctly.
If you sell your device to a new owner, it is not enough to simply disable the key. You need to log out of all accounts in the Settings -> Accounts and Sync menu and perform a full reset. Otherwise, the new owner will encounter a request for the password of the previous owner when you first set up.
💡
Deleting accounts before you dump or sell your phone is a critical step that ensures you don’t have any FRP blocking issues in the future.
