How to Disable Google Smart Lock on Xiaomi: The Complete Guide

Xiaomi smartphone owners often face a situation where the Smart Lock feature, which is designed to make it easier to access the device, begins to cause inconvenience. Instead of the expected automatic unlock when you are at home or wearing a smartwatch, the system can behave unpredictable, locking the screen at the most inopportune time or requiring constant password entry. This is especially annoying when the phone “forgets” a trusted Bluetooth device or misidentifies geolocation.

Disabling this feature is not just a matter of convenience, but often a necessity for data security. If you are selling a phone, transferring it to another user, or just want to get back to the classic method of protection, you will need to completely deactivate all active smart lock profiles. This process is not complicated, but requires care, since the settings are scattered across different parts of the system. MIUI Android.

In this article, we’ll look at all the ways you can disable the service, from standard menu settings to forced reset methods if the standard path is not available, how to remove trusted seats, devices and voice commands, and what to do if the feature is stuck and doesn’t want to shut down in the usual way.

Why you should consider turning off your Smart Lock

Google Smart Lock was introduced to improve the comfort of your smartphone, allowing you to bypass the lock screen in safe conditions. However, in practice, the algorithms for determining "security" often fail. For example, the phone may stop recognizing your location due to GPS error or lose connection to Bluetooth headphones, leaving the device unprotected in a public place.

There are also scenarios where having active unlock profiles creates vulnerabilities: If an attacker gains access to your trusted Bluetooth device or knows where you are, your Xiaomi's protection will be bypassed without entering a password.

⚠️ Warning: Before disabling all unlock methods, make sure you remember the basics PIN-Google account code, pattern lock or password. Once the Smart Lock is deactivated, the phone may require you to enter them immediately to confirm the changes.

Also worth noting is the impact of background geolocation services on battery autonomy. Constant location monitoring to check the conditions of the "Trusted Place" can significantly accelerate the discharge of a smartphone, especially on older Xiaomi models.

The classic method of disabling through security settings

The most reliable and correct way to remove Smart Lock is to use the regular Android settings menu. MIUI interface may vary slightly depending on the firmware version, but the logic remains the same. You will need access to the main settings menu and device administrator rights.

To start, go to Settings, then select Passwords and Security. In some versions of the shell, this item may be called simply Security or be located inside the Advanced Settings menu. Find the Screen Lock or Lock Type subsection, and that's where the key security settings are hidden.

Inside the lock menu, you need to find the Smart Lock (or Smart Lock) item, and the system will require you to enter your current password or fingerprint to verify your identity, a standard precaution to prevent unauthorized people from changing their security settings.

Once you enter the code, you'll see a list of active profiles: Trusted Locations, Trusted Devices, Activity Recognition. To turn off the function completely, you don't just turn off the switchboard, you sequentially remove all added items from each list, and only after cleaning all profiles, the function will stop working.

Removing trusted places and devices

The most commonly used profiles are Trusted Spaces and Trusted Devices, which are the ones that most often cause conflicts in the system, and if you're at home, but your phone is locked, or it's not locked at home, the problem is that you're settings.

To remove a trusted location, go to the appropriate section inside the Smart Lock menu, which will display a list of saved addresses with reference to Google Maps, click on the address you want to delete, and select the Remove option or basket icon. Repeat the procedure for all saved locations.

Similar actions are required for Bluetooth devices. In the Trusted Devices section, you will see a list of paired gadgets (watches, headphones, car stereo system). Select the device and click Forget or Delete. After that, Xiaomi will stop automatically unlocking when you connect to this gadget.

It is important to understand that simply turning off Bluetooth or GPS in the notification curtain does not cancel the Smart Lock settings. Profiles remain active in the system memory and are activated again as soon as you turn on the corresponding communication modules.

Resetting settings through Safe Mode

In rare cases, the settings interface may not work properly, preventing you from saving changes or removing a profile, which may be caused by a third-party application conflict or a system failure of MIUI.

Safe Mode triggers the Android operating system with all third-party apps disabled. This isolates the problem. To enter this mode on Xiaomi, press the off button, and then keep your finger on the "Stop" item on the screen for a long time until the suggestion to go to Safe Mode appears.

While in Safe Mode, repeat the Smart Lock shutdown procedure described above. Since third-party launchers and security utilities are not working, nothing should prevent you from making changes to your system settings. Once you successfully delete your profiles, just restart your phone in the usual way.

⚠️ Warning: In Safe Mode, some system applications may not display correctly or properly. Don't worry, this is normal behavior.

If the system does not allow you to change your settings in safe mode, the problem may lie deeper, for example, in the rights of the device administrator obtained by a third-party application. In this case, it is worth checking the Settings section → Passwords and security → Privacy → Special access → Device administrators and revoke suspicious rights.

💡

Use Google Assistant for quick status check: Ask “What devices are trusted?” and it will show active connections, even if you’re not on the settings menu.

Resetting the Internet with Google Find My Device

There is a situation where the user forgets the password and the Smart Lock stops working, leaving the phone locked, in which case the standard shutdown of the function is impossible without access to the system. However, if the phone is connected to the Internet, you can use the service Google Find My Device.

This is a radical method. It doesn't just turn off the Smart Lock, it erases all the data from the device, returning it to factory settings, and it's the only way to access the phone if you forget your password and the smart lock doesn't work.

To perform the procedure, go from your computer or other phone to android.com/find. Log in to the Google account that was used on the blocked Xiaomi. Select the device from the list and click on the Erase Device button.

Action: Clean the device


Result: Complete deletion of data and password reset




Required: Active Internet connection on the phone

Once reset, the phone will turn on as new, the Smart Lock feature will be completely deactivated, as all of its profiles will be deleted along with user data, you will have to reconfigure the phone and enter your Google account details for verification (FRP protection).

Frequent problems and their solutions

Even after completing all the steps, users may experience residual phenomena, such as the phone may continue to offer face or voice unlock even though the profiles are deleted, which is due to Google Play's caching of data.

To fix this, go to Settings → Apps → All apps. Go to Google Play Services. Go to Memory and click Clear Cache. Don't confuse "Clear all data," which is also safe in this case, but will require reconfiguration of some services.

Another common problem is the spontaneous activation of Activity Recognition, which uses an accelerometer and a gyroscope to determine if the phone is in your pocket, and if this option interferes, you need to turn it off separately inside the Smart Lock menu, because it is not geolocated.

💡

Disabling Smart Lock requires deleting all profiles (places, devices, activity) and possibly clearing the cache of Google services for the changes to take effect.

If the problem persists after all the manipulations, check for system updates. In Settings → About Phone → MIUI version, click on the update button. Xiaomi engineers regularly release patches that fix bugs with biometrics and smart locking.

Impact of disconnection on autonomy and productivity

Disabling Smart Lock has a positive effect on device life.As mentioned earlier, a constant survey GPS-The module and scanning of the Bluetooth environment consume battery power, and once these functions are turned off, the background load on the processor and radio modules decreases.

In addition, RAM is freed up. Services responsible for monitoring location and activity analysis are no longer resident in memory, which can make the MIUI work a little more responsive, especially on models with 3-4 GB of RAM.

But you have to consider the loss of convenience, you have to enter a password or put your finger on the scanner every time, and for many users, it's an acceptable price to pay for increased security and stability of the system, and the balance between convenience and security is a personal choice of each Xiaomi owner.

⚠️ WARNING: If you use your phone to work with corporate email or banking applications, disabling all quick unlock methods may be a requirement of your organization’s security policy.
