Owners of modern smartphones Xiaomi, Redmi and Poco often face a situation where the screen of the device turns into an information board, barely lighting up in your pocket or on the table. Notifications on a locked screen can contain sensitive data, such as codes from banking applications or private messages, available to anyone who takes the phone in their hands. In addition, the constant backlight of the display when new events arrive significantly accelerates battery discharge, which is critical at the end of the working day.
The MIUI interface and the new HyperOS shell provide flexible tools to manage this process, but they are often hidden in the depths of the menu or scattered across different settings. The user needs to understand the difference between completely disabling notifications and configuring them only after unlocking. In this article, we will take a detailed look at all available methods, from basic system settings to advanced tools for specific applications.
We'll look at how to set up Wallpaper Carousel, which often ignores system bans, and how to use Do Not Disturb mode to temporarily hide information. You'll learn to distinguish between system constraints and individual program settings, which will create the perfect balance between functionality and privacy. Remember that disabling preview messages in security settings affects all applications at once, which is the most radical but effective method.
Basic configuration of the content display in the system
The first step to order on your Xiaomi is to address the basic security and privacy settings. This is where the master switch controls the visibility of notification text when the device is in sleep mode. To access these settings, you need to open the main menu and go to Settings, then select Notifications and Status bar. In some versions of the firmware, this path may be slightly different, for example, through the Password and Security menu.
In the list of options that opens, you are interested in a item that can be called “Notification Format”, “Show Content” or “Notification Style on the Lock screen”. Here, the system offers you to choose whether the full text of the message will be displayed, only the name of the application or the content will be hidden completely. The option “Hide Content” is the best option for those who want to see the fact of the message but do not want to show the text to outsiders.
Importantly, the changes take effect instantly, but may require re-locking the screen for visualization. If you use an underscreen fingerprint scanner, the system can automatically display notifications immediately after successful unlocking, even if they were previously hidden.
You should also pay attention to the Always On Display settings if your Xiaomi model supports this feature. Wallpaper and personalization menu can be adjusted to see if new event icons will be displayed on a black background. Disabling this option will not only hide information, but also save battery life OLED-matrix.
Individual management for each application
Global settings are convenient, but sometimes you need finer granulation: for example, you want to see calls from Telegram, but hide emails from mail. MIUI and HyperOS have a personal control mechanism. Go to Settings → Notifications and Status bar → Notification management. Here is a complete list of all the apps installed on the device.
Select the desired application from the list, such as messenger or social network. In the menu that opens, find the switch "On the lock screen." By disabling it, you will prevent a particular application from displaying any signals on the locked display, even if the global settings allow it, this is the perfect way to remove spam from games or news aggregators, leaving important messages from loved ones.
☑️ Checking privacy settings
Special attention should be paid to banking and two-factor authorization applications, which recommend not just hiding text, but completely prohibiting the display of locks to avoid social engineering, and attackers can use information about who writes to you and when to build profiles.
⚠️ Note: When you turn off notifications on the messenger lock screen, you can skip an urgent call if the phone is down and the vibrator is off.
You can also prioritize this section, and some apps allow you to categorize notifications within your own settings, like Gmail, where you can split emails into important and promotional ones, and you can only disable the second one, but Xiaomi's system settings have a higher priority and will override the app's internal settings in case of conflict.
Customize wallpaper carousel and Always on Display
A separate headache for many users is the “Wallpaper Carousel” (Glance), which is often pre-installed on Redmi and Poco, has its own rules for displaying notifications that can ignore system bans. To curb this component, you need to go to the “Wallpaper Carousel” app or find it in the settings through a search.
Inside the Carousel settings, find the section associated with notifications or Display Mode. Often, the “Show Notifications” checkbox activates its own layer on top of the standard lock interface, and disabling this option will return control of the lock screen to standard Android tools.
Another problem for owners of flagship models with support for Always On Display (AOD) is that even when the screen is off, it can burn icons of new messages.
- 📱 Go to Settings. → Always on screen and lock.
- 🔍 Find the item "Style" or "Display Format».
- 🚫 Select the option “Do not show” or “Time only” to remove the icons of the application.
Why does the wallpaper carousel return after the blackout?
It is worth noting that some global firmware versions may have hidden AOD menus, which can help install a design theme that supports this functionality or use third-party widgets, although the latter require additional permissions and can affect autonomy.
Use of Do Not Disturb Mode and Schedules
If your goal is not a permanent ban, but a temporary restriction, such as during a sleep or meeting, use Do Not Disturb mode. Unlike simple silent mode, it completely blocks visual notifications from appearing on the screen, even if the device is unlocked (depending on the settings).
You can activate it through the notification curtain (swipe down from the top edge of the screen) or through Settings → Sound and vibration → Do not disturb. Here it is recommended to set the automatic activation on a schedule, for example, set the time from 23:00 to 07:00 to keep the phone screen black and calm at night.
An important feature is setting exceptions. Even in Do Not Disturb mode, you can allow interruptions for selected contacts or repeat calls. This ensures that you do not miss an emergency call, but that advertising and notifications from games will not wake you up in the middle of the night.
| Parameter | Regular regime | Don't disturb. | Air mode |
|---|---|---|---|
| The sound of notifications | There is. | No. | No. |
| Vibration. | There is. | No (usually) | No. |
| Screen upon receipt | It's on fire. | It's not on fire. | It's not on fire. |
| Internet access | There is. | There is. | No. |
| Incoming calls | Accepted | Reset/Silence | Inaccessibility |
💡
Do Not Disturb is a software filter that does not turn off radio modules, unlike air mode, so messages will continue to arrive but will be hidden from you until the regime change.
Hiding Notifications in Specific Use Scenarios
There are scenarios where standard settings are not enough, such as when you connect your smartphone to a Bluetooth headset or an Android Auto car system, notifications can be duplicated or unpredictable. → Bluetooth can find settings for each paired device and disable access to contacts and call logs, which indirectly affects notification synchronization.
Another important aspect is the work in games. Game Turbo has its own notification lock settings. By running the game through this mode, you can disable pop-ups (banners) that obscure the view. To set up, you need to call the Game Turbo menu with a swipe while playing and select "Do Not Disturb."
Also worth mentioning is third-party launchers. If you have replaced the standard Xiaomi desktop with Nova Launcher or another analog, lock screen management can go to the system or stay in the MIUI shell, depending on the version of Android. In such cases, it is better to rely on the system security settings described in the first section, as they have the highest priority.
⚠️ Note: Using third-party Lock Screen Apps on modern versions of Android can lead to conflicts and increased battery consumption. Android system strictly limits their capabilities, so it is recommended to use only a regular lock screen.
Solution: Notifications come without sound or screen
Sometimes users face the reverse problem: they have set up the phone but notifications have stopped coming at all, or come silently (no sound or screen) even when the phone is unlocked.This is often due to aggressive energy savings in MIUI. The system can "kill" the background processes of messengers.
To fix this, go to Settings → Apps → All apps, find the problem app and select AutoRun. Make sure the switch is activated. Also, in the Battery and Performance (or simply Battery) menu for a particular application, select No Limits mode, which will allow the application to run in the background and wake up the screen.
Another common reason is the Power Saving or Ultra-Saving modes, which force the system to disable background synchronization and notification visuals to extend battery life, and if you're critically aware of notifications, those modes will have to disable or add an app to the exclusion list.
💡
If notifications don’t come after all the settings, try resetting the network or app settings. Sometimes the notification cache overflows and causes a crash in Google Play Services, the push notification service.
