Where to find Smart Lock settings in MIUI and HyperOS

The path to the cherished menu can vary depending on the operating system version and regional firmware, and in most cases, you need to go to the basic settings of your smartphone and select the Passwords and Security section, and this is where all the access control tools are concentrated.

Inside this section, you should find Device Protection or Screen Lock. Once you enter your primary password, the system will open an additional menu where the Smart Lock option is usually located at the bottom of the list. In some builds, it may be called Smart Lock.

If you can't find this item through settings, try a global search on the system. Type the phrase "Smart Lock" or "smart lock" into the search bar, and the system will redirect you to the desired configuration menu.

Once you log in, the system will ask you to verify your identity again, which is a standard security procedure that ensures that the device owner changes the settings, and only after successful authorization will the list of available unlock methods be opened.

Configure trusted devices and Bluetooth

One of the most convenient use cases is unlocking when you connect to a particular gadget, which can be Bluetooth headphones, Amazfit smartwatches, or car stereo, and when the phone detects a connection to a trusted device, the screen stays open.

To get started, select Trusted Devices from the Smart Lock menu. Press the add button and wait for the system to scan the available gadgets. It is important that the device is pre-coupled with the phone via the standard Bluetooth menu.

You'll see all the connections you can get on the list. You'll pick the right device, like your Mi Band or your wireless headphones, and once you've confirmed your choice, your phone will remember that gadget and automatically keep the screen unlocked while the connection is active.

It's worth noting that a disconnect doesn't block the screen instantly, and there's a small time interval after which the phone will still need to enter a password, so that short-term signal interference doesn't interfere with the user.

Use of trusted locations and geolocation

Trusted Places allows your smartphone to stay unlocked when you are in a specific geographic location, ideal for your home or office, where the risk of device theft is minimal, and the accuracy of the device depends on the quality of the GPS and Wi-Fi signal.

To add a new point, select the appropriate item in the menu and click Add Trusted Place. You can select the current location or manually specify the address on the map. The system will suggest setting the range within which the lock will not be removed.

It is important to understand that to work this feature, the geolocation module must be constantly operating, which can lead to increased battery consumption, since the phone will continuously monitor your coordinates, and it is recommended to use this method only when urgently needed.

⚠️ Warning: Don't set the radius of the trusted zone too large.If the zone covers the entire area, the phone may remain unlocked in a public place, posing security risks.

In addition, in apartment buildings, the GPS signal can be unstable, in which case the system can periodically lock and unlock the screen if you are at the border of a given zone, and for stable indoor operation, it is better to rely on Wi-Fi networks, if this option is supported by your version of the software.

Face unlock and voice commands

Some Xiaomi models support face unlock in conjunction with Smart Lock. Unlike the standard Face ID, which only works when the screen is turned on, Smart Lock can keep the device unlocked while the camera “sees” the owner.

This feature is called On-body detection, or body detection, but it works differently in the context of faces. The phone uses a front-facing camera to periodically check the owner's presence. If you hold the phone in your hand and look at it, the screen won't go out.

Voice commands can also act as a trigger: You can set the phone to remain unlocked when the owner's voice is recognized through Google Assistant, but this method is less reliable and often requires active interaction with the screen.

• 👤 Set up a face model in the "Face Block" section for basic work.
• 👁 Activate the “Remain Unlocked” option in the advanced face settings.
• 🎤 Use Voice Match to activate voice functions without password.

Keep in mind that the constant operation of the camera and microphone for data analysis can raise privacy issues. AI-module increases.

Smart Lock problems and their solution

Users often face a situation where the configured feature stops working, the screen goes out and locks, despite the presence of a trusted device nearby, and most often the problem lies in the aggressive optimization of the battery, characteristic of MIUI.

The power saving system can force Bluetooth or GPS to be turned off in the background to save energy, so to fix this, you need to find the Google Play app or system lock process in the settings and remove background activity restrictions.

It also helps to clean the geolocation cache, go to application management, find Google Play services, and clean the cache, and then you need to restart the device and re-configure the trusted areas.

Aggressive energy savings are the main reason why Xiaomi’s Smart Lock fails. be sure to set up exceptions for system services.

If the problem persists, check if Do Not Disturb mode or special profiles are enabled that can intercept control of the screen lock.Resetting network settings can also help restore the Bluetooth module to work properly.
