Owning a modern Xiaomi or Redmi smartphone involves a constant flow of information that comes in the form of messaging messages, emails and system alerts. However, it often happens that at the time of a call or an incoming notification, not only the name of the sender is displayed on the lock screen, but also the full text of the message, which can be a serious problem for privacy, especially if the device is in the hands of unauthorized people or lying on the desktop in the office.
Fortunately, the MIUI shell and the new HyperOS provide flexible tools to manage this behavior, so you can completely disable content from displaying content, leaving only an app icon, or configure filtering for specific programs, which will help to maintain a balance between the speed of obtaining information and protecting personal data from prying eyes.
In this article, we will take a detailed look at the algorithm that will allow you to hide sensitive data. We will look at both system security settings and individual settings for each application so that you can configure your gadget as efficiently as possible.
⚠️ Note: Menu interface in different versions of firmware (Global, China, EEA) The names of the items may differ slightly, but the logic of actions remains the same for all models.
Configuring global privacy in the system
The first step to protecting your communications is to change the system settings of the display. By default, the system seeks to show the user as much information as possible at once, but this option changes easily in the security section. You need to go to the Settings menu and find the item responsible for notifications and status bar.
Depending on the version of the shell, the path may look like Notifications and Status Bar, or be inside the Password and Security section. This is where the key switch that controls the visibility of content on the locked screen hides. Find the option to Show the content of notifications or similar wording.
Once you click on this section, you'll see a few different behaviors: Select Hide Content or Don't Show on a locked screen. Once activated, all incoming messages will come as a "New Notice" plug, or simply display the name of the app without text.
It’s worth noting that changing this setting will affect all apps at once, which is convenient if you want to quickly restrict access to all information, but less flexible if you only need to hide correspondence in one particular messenger.
Individual setting for each application
A more subtle setup is available through the application-specific management menu, which allows you to leave the text of notifications from email or news aggregators open, but completely hide the content of messages from Telegram, WhatsApp or Viber. To do this, go to Settings → Notifications → Notification Management.
In the list that opens, find the application you want, like the messenger you want to hide, click on the program name to open the detailed menu of its alerts, and you will need to find the Locked Screen or Lock Screen section.
The system will offer three options: show everything, hide content or not show notifications at all. Choose Hide content. Now, even if the global settings allow text to be displayed, this particular application will be banned.
☑️ Checking privacy settings
Repeat this procedure for all applications that contain sensitive information, which will take a few minutes, but will provide maximum privacy when the phone is lying upside down in the company of other people.
Use of "Do Not Disturb" and Schedules
Sometimes you don't have to hide text all the time, but only at certain times, like during meetings, in the movies or at night. Xiaomi's Do Not Disturb mode is perfect for this purpose. It not only blocks sound and vibration, but can also hide the visual display of notifications on the lock screen.
You can activate this mode through a quick access curtain or in audio settings. However, the most effective way to use automation. In the Do Not Disturb mode menu, find the option "Schedule Enable" or "Smart Mode" that allows the system to independently go into hidden mode at a given time.
And you also need to look at sleep mode, which is often integrated into digital well-being, which not only limits phone use, but also changes the behavior of the lock screen, making it as minimal and non-distracting as possible.
⚠️ Warning: In Do Not Disturb mode, notifications may not only be hidden, but they may not wake the screen at all. Check the screen's behavior settings if you're waiting for an important call.
Using schedules is a great way to remember to turn on privacy at the right time, you can set up a "Cinema" or "Meeting" profile that will be activated by geolocation or time, automatically hiding the text of messages.
Features of work in the shell of HyperOS
With the release of the new HyperOS shell, which gradually replaces MIUI on the new Xiaomi 14, Redmi Note 13 and others, the location of some settings has changed. Logic has remained the same, but the visual design and paths have become deeper.
HyperOS has a privacy protection section, which can include Hiding Notification Content, which works globally, and the new system has improved notifications on Always-On Display (always on screen).
If you have a new version of the software, pay attention to the Always-On Display settings. HyperOS can separately configure whether to show the notification text on the screen off or show only the icon, which saves battery power and increases privacy.
What to do if the settings are reset?
HyperOS users also have extended control over smart notifications that the system itself flags as important, and check if the smart assent displays the content of such messages bypassing your settings.
Comparison of methods of concealment of information
To make it easier to choose the best protection method, we have prepared a comparative table that will help you understand which method is best suited to your current tasks: permanent protection, temporary or selective.
| Method | Level of privacy | Impact on convenience | Flexibility |
|---|---|---|---|
| Global cover-up | High (all annexes) | Low (you need to unlock to read) | Low. |
| Set-up by application | Medium (selectively) | Medium (important visible, personal hidden) | Tall. |
| Don't disturb mode. | Tall (temporary) | High (outside the schedule does not interfere) | Medium |
| Hiding at AOD | Medium (only on the off screen) | High (saving battery) | Medium |
As you can see from the table, the most versatile solution is a combination of methods, such as global concealment of content on a locked screen, combined with customizations for important work chats where text is needed.
Using a spreadsheet will help you navigate quickly if standard settings seem confusing. Choose a strategy that fits your lifestyle.
Additional Security Measures for Locking Screen
Hiding notification text is just one layer of protection. To fully secure data on a locked Xiaomi, it is recommended to use additional features. One of them is Pocket Mode, which prevents accidental taps and activation of the screen in the bag, which can sometimes lead to leakage of information through previews.
You should also pay attention to the Up to Turn feature, which means that if you turn off this option, the screen won’t light up every time you pick up your phone, which reduces the risk that the person next to you will have time to read the notification.
💡
Use guest mode or a second space to transfer your phone to other people so they won’t see your personal notifications accurately even when the device is unlocked.
Don't forget about biometrics: Face recognition or fingerprint settings allow you to quickly open your phone to read a message, minimizing the time that text spends on the screen in the public domain.
Solving Display Problems
Sometimes users are faced with a situation where the settings are applied, but the text still seeps on the screen, most often this is due to the peculiarities of the work of specific applications, which have their own internal notification settings, overlapping the system.
Check the settings inside the messenger itself, for example, in Telegram or WhatsApp, the Notifications section may have a tick on the Display Messages section, which must be removed to allow the Android and MIUI system restrictions to take effect.
⚠️ Warning: Some optimizers and memory cleaners may reset notification services temporarily by resetting settings. If the problem occurs periodically, try turning off aggressive memory cleanup for system processes.
If nothing helps, try resetting notification settings for the problem app through the Apps menu → All Apps → All Apps → Clear the data (select only Clear the cache or Reset without deleting your account details).This will return the permissions to factory ones, and you can configure them again correctly.
💡
A comprehensive approach, including system settings, in-app settings and the use of scripting modes, guarantees maximum confidentiality of your correspondence.
