Xiaomi and Redmi smartphone owners often face the need to change their security settings to gain full control of the device.The Smart Lock feature, integrated into the Android operating system, is designed to make it easier to access the gadget by automatically unlocking it under certain conditions.However, sometimes this option starts to work incorrectly or simply ceases to be relevant to the user, requiring complete removal.
The process of deactivation can seem confusing, especially if the system menu has been updated or translated into another language.In this article, we will discuss in detail all the ways to remove Google Smart Lock and reset the settings of trusted places and devices, you will learn how to avoid blocking an account and what to do if standard methods do not work.
Incorrectly configured or frozen security can cause the phone to stop responding to normal actions, leaving the user in front of a black screen. Understanding how to manage these parameters is a key skill for any MIUI owner. Let's figure out how to return the system to the original security settings.
What is a Smart Lock and Why You Should Remove It
Smart Lock is a security tool that allows you to unlock your device without input. PIN-This includes being in a trusted location, connecting to a Bluetooth headset, or being on the body (on-body detection). MIUI, Sometimes it causes conflicts.
Users often decide to remove Smart Lock settings for several reasons: First, the feature can work unstable: the phone stops locking at the right moments or, conversely, does not unlock when necessary. Second, selling the device or transferring it to another person requires a complete reset of all bindings. Third, some users simply prefer the maximum level of protection, eliminating any automatic exceptions.
⚠️ Note: Before making changes to your security settings, make sure you remember your primary password, PIN-Unlock code or graphical key.Resetting Smart Lock settings may require re-authorization.
It's important to understand that you can't completely remove a component without superuser rights, because it's a Google system service. But we're talking about disabling features and clearing data, which completely solves the problem of auto-unlocking, and it returns the device to standard behavior, requiring proof of identity every time you turn on the screen.
Preparing for resetting security settings
Before you start taking action on the settings menu, you need to follow a number of preparatory steps.This will help you avoid the situation where you accidentally block access to your Redmi Note or Mi. First of all, make sure that the battery charge is at least 30-40% so that the phone does not turn off at a critical moment.
It's also worth checking which trusted devices or locations are currently active, so you can understand the scale of the change, and if you have Bluetooth headphones or smartwatches connected, you'd better temporarily disable them or remove them from the list of paired devices so they don't interfere with the setup process.
☑️ Preparing for the removal of Smart Lock
Another important aspect is having access to a Google account. Since Smart Lock is a Google service, in some cases (especially after a reset) the system may request confirmation of the account holder.
Removing trusted devices and locations
The most common scenario is to remove specific triggers that trigger automatic unlocking, which could be your favorite headphones, your car stereo, or your home address, and you need to go to the appropriate security settings menu first.
Go through Settings → Passwords & Security → Device Protection (or Screen Lock). In some versions of MIUI, this item may simply be called "Screen Lock and Password." Find the Smart Lock section and click on it. The system will ask you to enter your current unlock password.
Inside the menu, you will see several categories: “Trusted Devices”, “Trusted Places” and “Voice Recognition”.
- 📍 Trusted Places: Click on this, select the saved address (such as "Home" or "Work") and click on the "Delete" button or the basket icon. This will cause the phone to request the password again when in this geolocation.
- 🎧 Trusted Devices: This displays a list of all Bluetooth gadgets that can unlock your phone. Select the device from the list and click "Forget" or "Delete".
- 🗣 Voice recognition: If the unlock phrase has been configured, it must also be deleted by pressing the appropriate data clearing button.
Why is the trusted device not removed?
Once all items are removed from the lists, the Smart Lock function will effectively stop working, as it will not have the conditions to automatically unlock, but the data about the setup itself can be stored in the system cache.
Complete data cleanup of Google Play services
If simply removing trusted points doesn’t work, or if the Smart Lock menu is error-prone, a deeper approach will be needed: Clear the data of the services responsible for running Google services on your Xiaomi. This action is safe for your personal files, but resets some system features.
Go to Settings → Apps → All Apps. Search Google Play Services (Google Play Services) on the list. Don't confuse it with the regular Play Market store. Click on the app, then select Memory or Storage.
On the screen that opens, you'll see the Clear Data button. Press it and confirm the action in the pop-up window. Importantly, this action will reset the Smart Lock settings to factory settings, removing all the saved access keys.
| System component | Action. | The result |
|---|---|---|
| Google Play Services | Clear all data | Full reset of Smart Lock and synchronization |
| Google Play Store | Clear the cache | Resolving service update errors |
| Settings (System) | Clear the cache | Resetting temporary interface files |
| Security (Mi Security) | Clear the cache | Updating the database of viruses and settings |
💡
Cleaning up Google Play Services data is the most effective way to forcefully reset your Smart Lock settings if standard deletion doesn’t work.
After this procedure, restart your smartphone. When you first turn on, the system can configure Google services for a while, so give it 5-10 minutes.
Problems with access and blocking of the account
Sometimes users are faced with a situation where, after trying to change the settings or delete Smart Lock, the phone requires a confirmation of Google account (FRP - Factory Reset Protection), which is a protective mechanism designed to prevent theft of the device. If you forget your password, access to the phone may be limited.
If the system claims that the security settings have changed and requires you to enter an old password that you don't remember, the situation gets complicated. On modern versions of Android and MIUI, it's almost impossible to get around this without losing data. The only legal way is to restore access through the Google account recovery form on another device.
⚠️ Attention: Attempts at hacking FRP or bypassing the account lock with the help of third-party software can lead to complete inoperability of the Xiaomi smartphone and loss of warranty.
If the problem is that the phone has “forgot” the password from the Smart Lock, but you remember the main one. PIN-code, just reset the data as described in the previous section. The main thing is not to panic and act consistently. Entering the wrong password too many times can temporarily lock the device for 30 seconds, 5 minutes or even 24 hours.
Alternative methods of unlocking on MIUI
Once you’ve managed to remove Google Smart Lock, you may wonder how to replace it for convenience: MIUI’s shell offers customized, often more flexible biometric security tools that don’t depend on Google’s services.
Xiaomi owners can use:
- 👆 Fingerprint unlock: Works faster and more reliable than voice or geolocation. → Passwords and security → Fingerprints.
- 👤 Face unlock: Uses a front-facing camera.While it's less secure than a print, for many users it's a trade-off between speed and protection.
- ⌚ Unlocking through Mi Band: If you have a Mi Band fitness bracelet, the Mi Fitness app (formerly Mi Fit) lets you unlock your phone when the bracelet is on your hand.This works more stable than the standard Smart Lock.
Using native MIUI features is preferable as they are better optimized for the Snapdragon and MediaTek processors used in Xiaomi phones and consume less battery power in the background.
💡
Use the “Second Space” feature on Xiaomi if you want to completely isolate your personal data from the main system without relying on external locking services.
