Modern smartphones have become repositories for our personal lives, and the lock screen is often the first place where sensitive information becomes visible to strangers. Owners of devices based on Xiaomi shell MIUI or HyperOS are often faced with the need to hide the contents of incoming messages, calls or notifications from instant messengers. This is not just a matter of convenience, but a basic level digital hygienethat allows you to protect correspondence from prying eyes on public transport or the office.
Fortunately, the Android system provides flexible tools for controlling what is displayed on a locked display. You can completely disable the display of notifications, leave only application icons, or set a complete ban on text previews. Understanding how these settings work in the ecosystem will help you create a personalized level of privacy without compromising the functionality of the device. In this guide, we'll take a closer look at all the available methods of hiding information, from global system settings to individual settings for specific applications. We will look at the interface features Xiaomi, will help you create a personalized level of privacy without compromising the functionality of the device.
In this guide, we will examine in detail all the available methods of hiding information, from global system settings to individual settings for specific applications. We will look at the interface features MIUIthat may differ from stock Android, and give recommendations on the optimal configuration for maximum security of your data.
Global lock screen settings in MIUI
The first step to control the visibility of data is to access the system security settings. In the shell MIUI these settings are often hidden deeper than in standard Android to prevent accidental changes to critical security settings. First, you need to go to the section Settings and find the item responsible for passwords and security.
Here is the key switch that controls the display of content. Find the subsection Privacy or Lock screen (depending on the firmware version). It is in this menu that the option "Show notification contents"is located. If this toggle switch is active, anyone who picks up your phone will be able to read the text of the message without unlocking the device.
- 🔒 Complete disable - hides icons and notification text until you enter the password.
- 👁️ Hiding text - shows the application icon, but hides the text of the message.
- 🔔 Sound alert - the phone vibrates or makes a sound, but the screen remains dark.
Disabling this function leads to the fact that only a general “Notifications” message appears on the lock screen or they disappear completely until the owner authorizes. This is the most reliable way to protect information, but it requires constant password entry or the use of a fingerprint scanner to check incoming events.
⚠️ Attention: After updating the firmware to a new version HyperOS the location of the privacy menu may change. If you do not find the desired item in the specified location, use the search in the settings by entering the query “notifications”.
Individual settings for specific applications
Often users do not require a total ban, but selective hiding of information only from certain services, such as Telegram, WhatsApp or banking applications. The system Xiaomi allows you to flexibly configure the behavior of notifications for each installed software separately. This makes it possible to see important system alerts, but hide personal messages.
To implement this scheme, you need to go to the menu Settings → Notifications and status bar → Manage notifications. In the list that opens, select the application you are interested in. Inside the settings menu for a specific application, find the switch "On the lock screen". Here you can select the “Show notifications”, “Do not show notifications” or “Show but hide contents” mode.
This approach is especially relevant for corporate devices or phones used by several family members. You can leave notifications about missed calls or calendar visible, but completely block access to instant messengers. The system remembers these settings even after rebooting the device.
☑️ Checking privacy settings
It is worth noting that some applications have their own internal privacy settings, which may override the system ones. For example, in the settings itself WhatsApp there is an item “Show notifications”, which also affects the display of data on the locked screen. It is recommended to check the settings both in the system and within the application to achieve maximum effect.
Using Do Not Disturb mode and schedules
An alternative method of hiding information is to use the built-in mode "Do not disturb" (Do Not Disturb). This tool allows you to not just hide content, but completely suppress visual and audio signals at a given time or under certain conditions. This is an ideal solution for night time or important meetings.
You can activate this mode through the notification shade or in the sound settings. In the advanced mode settings Do not disturb you can configure the rules for displaying notifications on the lock screen. You can allow only selected contacts to be shown or completely prohibit any pop-up windows.
Settings → Sound and vibration → Do not disturb → Rules → Lock screenImplementation features in MIUI is the ability to create automatic schedules. You can set your phone to automatically hide all notifications on the lock screen from 23:00 to 07:00. This eliminates the need to manually turn on the mode every evening and ensures a restful sleep without light irritants.
Secret hiding function
In some versions of MIUI, there is a hidden “Smart Lock” setting that uses proximity sensor data. If your phone is face down or in your pocket, notifications won't light up, even if your settings allow them to appear. This saves battery power and increases privacy.
Hide application icons and indicators
Even if the message text is hidden, the application icon on the lock screen can give away the essence of what is happening. For example, an icon for a bank or a specific service can tell a viewer about your financial transactions or interests. The interface settings Xiaomi provide the ability to completely remove visual markers of new events.
To do this, go to the section Settings → Notifications and status bar. Here is the option "Notification light" or "Light indicator". Disabling these features will result in the phone not showing any outward signs of receiving new information until you unlock it.
| Indicator type | Where to disable | Disable effect |
|---|---|---|
| Icon on the icon | Application settings | The red circle with the number does not appear |
| LED | Additional settings | The light does not blink when a message is received |
| Pop-up window | Manage notifications | The banner does not appear on top of other applications |
| Sound/Vibration | Sound profile | Complete silence when data arrives |
Completely turning off visual indicators makes the device as invisible as possible in terms of incoming information. However, the user should remember that in this mode it is easy to miss an important call or urgent message if the phone is in a bag or another room.
⚠️ Warning: Turning off the indicator light and icons may cause you to forget to check messages for a long time. It is recommended to leave at least one unobtrusive notification method, for example, vibration.
Features of working with protected folders and second space
Smartphone owners Xiaomi have access to a unique function "Second Space" or protected folders. This is actually the creation of a second user profile within one device with a separate set of applications and settings. Notifications from apps installed in Second Space are not displayed on the main profile lock screen by default.
This is a powerful tool for separating your work and personal life. You can install work instant messengers and mail in the Second Space. Even if the phone is unlocked in the main profile, notifications from the “work” zone will not pop up until you switch to the appropriate mode or enter a special password/fingerprint.
This function is configured through the menu Settings → About phone (or in advanced settings) → Second space. After activating and configuring the separation password, the system automatically isolates data streams. This is the best way to hide notifications not only from strangers, but also from yourself during non-working hours.
Use different fingerprints to enter the Main and Second space. Set up your phone so that one finger opens your personal profile and the other finger opens your work profile. This will allow you to instantly switch context and hide unnecessary notifications with one touch.
Solving problems with disappearing notifications
Sometimes users are faced with a situation where notifications are not just hidden by settings, but disappear on their own or do not appear on the lock screen at all. This may be due to the aggressive power saving system MIUI, which “kills” background processes of applications to save battery power.
To fix this, you need to go to the settings of a specific application, find the section Activity control or Autostart and select the mode "No restrictions". Also check whether autorun is enabled for the desired apps in the corresponding settings menu. Without permission to run in the background, the application will not be able to send a signal to the lock screen.
Another reason may be that the "Energy Saving" mode is turned on. In this mode, the system limits the screen refresh rate and background services, resulting in delayed or missing notifications. If it is critical for you to receive notifications instantly, disable the power saving mode or add important applications to exceptions.
⚠️ Attention: The interface of the energy saving and autorun settings may differ significantly on different versions of Android (11, 12, 13, 14) and MIUI shells. If you cannot find the "No restrictions" option, check the official manual for your specific device model.
Aggressive battery optimization is the main reason for missing notifications on Xiaomi. Allowing background work solves 90% of message delivery problems.
Frequently asked questions (FAQ)

Why do notifications still light up after locking the screen?
Most likely, you have the “Rise to Wake” or “Double Tap to Wake” function enabled. Check your lock screen settings and turn off features that activate the display when you move your phone. Also check the Always On Display settings.
Does hiding notifications affect the alarm?
No, the alarm is a high-priority system function. Even in Do Not Disturb mode or when notifications are completely hidden, the alarm will go off at the set time, unless you specifically turned it off in the silent mode settings.
How to return notification settings to default?
You can reset notification settings for all applications at once through the "Applications" menu → "Manage applications" → three dots in the corner → “Reset application settings”. This will return all permissions and display settings to the factory state.
Is it safe to use third-party apps to block notifications?
Using third-party launchers or blockers requires you to grant broad permissions to access your data. It is recommended to use only built-in tools MIUIas they work at the system level and do not require transfer of data to third parties.
