How to disable the screensaver on Xiaomi 12: the complete guide

Owners of flagship Xiaomi 12 devices often encounter intrusive interface elements that the developers of MIUI or HyperOS add to visual decoration. One such element is the screensaver that appears when the screen is turned on or the device goes to sleep. Many users prefer minimalism and want to see only time or a clean desktop without unnecessary logos and animations on the display.

The deactivation process depends on what type of screensaver you are concerned about: the system logo when you boot, wallpaper in standby mode (Always On Display) or advertising slides on the lock screen. In this article, we will discuss in detail all possible options for settings for the Xiaomi 12 model, you will learn how to manage the system parameters of the display and get rid of unnecessary visual noise.

Before making changes, it’s worth noting that the interface may vary slightly depending on the version of the operating system.However, the basic algorithms of actions remain the same for the entire Xiaomi smartphone line. Follow the instructions below to customize the device to your personal preferences.

Differences in MIUI and HyperOS types

Users often confuse the different kinds of static or animated images that appear on the screen. On Xiaomi 12, the term "savenger" can mean three completely different interface elements. Understanding these differences is critical to getting the right setup.

The first type is Always On Display (AOD), which shows the time and notifications on the screen off. The second type is the Wallpaper Carousel, which changes the background images on a locked phone. The third option is the classic screensaver, which is activated when the charger is connected or in standby mode.

• 📱 Lock screen: An image that is visible immediately after the device wakes up before entering the password.
• ⏰ Always on screen: Dim time indication on a black background, running constantly.
• 🔌 Screen saver: A mode activated when charging, showing a clock or slideshow.

It is important to distinguish between these terms, as the settings for each are in different sections of the menu. Misunderstanding the term can lead to the fact that you will look for the setting in the wrong place where it is located.

⚠️ Warning: Disabling system screensavers does not affect the operation of the phone’s core functions, but can change the look of the lock interface.

In some versions of the firmware, menu items can be translated differently, so focus on the semantic content of the feature description. If you do not find an exact match of the name, look for a similar parameter.

Always on Display on Xiaomi 12

Always On Display is one of the most popular, but also the most energy-consuming. If your goal is to completely remove any glow from the screen in sleep mode, this section is for you. AMOLED-This function is implemented very flexibly.

You need to go to settings first. Open the Settings app and find the Lock Screen section. In some shell versions, this item may simply be called Lock. This is where the basic controls of the sleep mode visual elements are concentrated.

Inside the menu, find Always on and the lock screen or just Always on. Here you will see a switch that activates or deactivates the function. Turn it to the Off position so that the screen goes off completely when you lock it.

You should also pay attention to the AOD schedule. Even if the feature is on, it can only work at certain times of the day. You can set it up automatically only when you receive notifications, which will save battery power.

• 🔋 Energy savings: total shutdown AOD extends the time of autonomous operation.
• 🕒 Schedule: you can set up work only during the day or working hours.
• 🔔 Reaction to notifications: the screen only lights up when new messages are posted.

⚠️ Note: Some global firmware versions have a clause AOD It can be hidden or renamed as the “Notification Indicator».

After making changes, it is recommended to lock the screen and check the result. If the image still appears, it is possible that a third-party widget or theme is activated, which has its own display settings.

Removal of wallpaper carousel and advertising slides

One of the most annoying features for many users is the Wallpaper Carousel, a service that automatically changes background images on the lock screen and often contains promotional offers. On Xiaomi 12, disabling this feature returns a static image.

To get rid of the constant change of pictures, go to Settings → Lock screen. Find a item called Wallpaper Carousel. Inside this menu will be the main switch that you need to deactivate. Once the carousel is turned off, the standard static image will return.

Also, check the theme settings. If you use a third-party theme from Themes, it may have scripts built in to change the screensavers, in which case it is recommended to reset the theme to standard or check the settings of a specific theme in the Themes app.

It is also important to check the Get recommendations inside the carousel settings section. Even with the carousel turned off, this item can continue to load advertising content in the background, consuming traffic.

• 🚫 Complete shutdown: removes image change and banner ads.
• 🎨 Static background: your selected photo is returned to lock.
• 📉 Traffic: Phone stops downloading new images.

If after all the manipulations, the advertising or image change continues, try clearing the cache of the Wallpaper Carousel application through the application management menu, which will help to reset possible caching errors.

Setting up the screen saver when charging

There is a separate type of screensaver on Android that is activated exclusively while charging the device or at the docking station. On Xiaomi 12, this mode often stays on by default, showing large hours or slideshows while the phone is connected to the network.

To manage this setting, use the hidden developer menu or standard settings if available in your version of the OS. Go to Settings → Additional → Developer Mode. If the developer menu is hidden, click 7 times on the build number in the About Phone section.

In developer mode, find the "Savenger" (or Dreams) option. Click on it and select "No." This action completely prevents the system from running any screensavers while charging. The screen will go out according to the sleep timer, not including the clock mode.

It is also worth checking the settings of the Watch or Alarm Watch app, which in some cases take over the time display function when connecting the charge, ignoring the system settings of the screensaver.

Make sure you don’t confuse this mode with Night Mode or Sleep Mode, which can also change the behavior of the screen at certain times of the day.

Management of themes and third-party launchers

Sometimes standard settings don’t work because a third-party app or theme is responsible for the screensaver.Themes store on Xiaomi 12 offers thousands of designs, many of which force you to change the lock screen.

Check which theme is active now. Go to the Themes → Profile → Themes. If you choose a theme other than Classic or Standard, try switching to standard. This will instantly remove all custom screensavers and animations, returning the factory look.

If you use a third-party launcher (for example, Nova Launcher or Microsoft Launcher), it may have its own lock screen settings, in which case you need to go to the launcher settings and find the item responsible for locking or widgets on the locked screen there.

• 🎭 Reset theme: Returns all visual elements to factory.
• 🛠️ Launcher settings: check third-party desktop apps.
• 📲 Widgets: Some widgets can simulate the screensaver.

💡

Before installing a new theme from the store, always look at the lock screen screen screenshots in the description, often where unwanted screensavers are hidden that cannot be removed in the phone settings.

Also, look at the widgets you installed on your desktop, and watch or frame widgets can be activated under certain conditions, giving you the illusion of a working system saver.

In rare cases, memory cleaner apps or antiviruses that have a "lock" feature to protect against children can cause the problem.

Resetting display settings and eliminating errors

If none of the above methods helped disable the screensaver on Xiaomi 12, it is possible that the system has suffered a software failure, the configuration files of the display may have been corrupted, or the settings may have been changed at the system cache level.

The first step is to delete the system’s temporary files. Go to Settings → Advanced Settings → Restore and Reset. Don’t rush to make a full reset! Find a cache cleaner or use the built-in Security → Cleanup app.

In more complex cases, you may need to reset all settings to factory settings.This action will delete all your data, so be sure to back up your contacts, photos and documents before starting the procedure. After the reset, the phone will return to the “out of the box” state and all third-party settings of the screensavers will disappear.

⚠️ Note: Wipe Data deletes all user data, and use this method only if other methods have not helped.

Also worth checking for system updates. In the About Phone section, click on the MIUI/HyperOS version. Developers often release patches that fix interface bugs, including screensaver display problems.

If the problem persists even after a complete reset and upgrade, it may indicate a hardware malfunction of the display controller, although for the Xiaomi 12 model, such cases are extremely rare.
