Owning a modern Xiaomi or Redmi smartphone involves the active use of instant messengers and social networks that constantly send notifications. However, when the device is lying on a desk in the office or lying on a charge in the living room, the screen lights up, and anyone passing by can read personal correspondence or see the confirmation code from the bank, this creates a real threat of leakage of confidential information, which is often forgotten by ordinary users.
Fortunately, MIUI and the new HyperOS offer flexible privacy management tools, so you can leave only app names or remove previews of messages while still being able to respond quickly to important calls. In this article, we’ll detail how to set up a lock screen so that your data is only yours.
The setup process does not require superuser rights or complex flashing of the device. All the necessary functions are built into the standard interface of Xiaomi. We will look at both global system settings and individual parameters for each application, which will allow you to create a multi-layered protection of your digital life.
Global privacy settings in MIUI and HyperOS
The first step to complete privacy is to change the system settings that control the lock screen behavior for all applications at once, which is a basic layer of protection that hides text in pop-ups and on the locked screen. To get to the desired menu, you need to open Settings and go to the Notifications and Status bar section, and here is the key switch that displays content.
You'll need to find a item that might be called "Notification Format" or "Notification Content." The default is to show everything, but to improve security, you'll need to select "Hide Content" option. Once you activate this feature, instead of the text of the message, the screen will display the phrase "New Notification" or just the name of the application, such as Telegram or WhatsApp.
It is worth noting that the menu may differ slightly from firmware to firmware, and in some cases the setting is in the Security and Privacy section -> Privacy. If you can't find the settings right away, search the settings by querying "content" or "lock."
After changing the global settings, the system will stop showing previews of messages on the locked screen, but in the unlocked state, text can remain visible in the curtain. To correct this, you need to check the settings of a particular application or use the Hiding Content function in the general notification settings, which applies to the active session.
Individual display setting for applications
Global text hiding is convenient, but sometimes requires finer customization. For example, you may want to hide text only from messengers, but leave visible notifications from an email client or news aggregators. MIUI provides the ability to manage each application separately through the Settings menu -> Notifications and Status bar -> Application Notifications.
In the list that opens, find the app you want, like Viber or Instagram, and click on it to reveal the details. You're interested in the Notification Format or Hide Content Switch, and you're forced to stop the system from showing text from that particular source on the lock screen when you activate it, even if the rule doesn't apply to other applications.
This allows for a flexible alert system, where you can leave the notifications of missed calls or alarms visible, because they don't carry sensitive information, while messaging is securely hidden, and this is especially true for corporate smartphones, where different people can use the device.
☑️ Checking privacy settings
For example, Telegram or WhatsApp have “Show preview” options inside the app itself, and it is recommended to check them to ensure maximum privacy.
Using the Pocket mode and blocking previews
One of the most useful features for Xiaomi owners is Pocket Mode, which prevents the screen from accidentally turning on in your pocket or bag, but is also closely related to the logic of displaying notifications. Although the mode's primary function is to protect against false pressing, it affects how often the screen lights up -> Lock screen -> Pocket mode.
And then there's the concept of notification previews, which are little pop-ups that appear at the top of the screen even when you're using other apps, and you can also turn them off or configure them to not show text, so you can find the notification settings for a particular app and select the option "Do not show" or "Icon Only."
Turning off previews is especially important when using a navigator or watching a full-screen video, at which point any pop-up message can obscure important information on a map or frame of a movie, and by hiding the content, you can save yourself from having to swipe annoying plaques every time.
⚠️ Warning: Disabling preview notifications may cause you to miss an urgent message if you don't regularly check the status bar or notification center.Be careful if you expect an important code or call.
Also worth mentioning is the Blinking Indicator feature, which makes the LED (if it is in the model) or screen blink when a new message is sent. Xiaomi’s new LED-free models use a screen blinking simulation. This feature can also be configured to avoid drawing too much attention to the device in the dark.
Customize Always On Display and Widgets
Modern. AMOLED-The screens allow you to use the Always On Display feature, which shows the time, date and notifications even when the phone is locked, and it's a beautiful, but potentially privacy-defying tool to hide the text of messages on the phone. AOD, Go to Settings -> Wallpaper and personalization -> Always on screen.
Inside the AOD menu, find your style or format settings, and you can choose between the option that only shows the app icons without text, or you can turn off notifications completely on the screen that is off, ensuring that no one in a dark room or meeting can read your message just by looking at the phone that is lying down.
Some MIUI themes may have their own notification widgets on the lock screen that ignore system settings. If you have set a third-party theme and notice that the text still shines through, try changing the theme to a standard one or checking the widget settings in the Themes app.
Why is the text visible after setting up?
Users who appreciate minimalism are advised to completely disable the display of notification details on AOD, leaving only the clock, which will not only increase privacy, but also save a little battery power, since the screen does not have to light up to render text.
Comparison of methods of concealment of information
Once you've figured out the individual settings, it's helpful to organize the information to see which method is best suited to your situation, and different approaches have their advantages and disadvantages depending on the smartphone model and the operating system version.
| Method of setting up | Level of concealment | Impact on convenience | Where to find out. |
|---|---|---|---|
| Global cover-up | High (all annexes) | Medium (you need to unlock for reading) | Settings -> Notifications |
| Set-up of the application | Selective | Low (flexibility) | Notifications -> Annexes |
| Shutting down previews | Medium (pop-up only) | High (does not interfere with work) | Settings of a specific application |
| AOD without text | High (off screen) | Low (clock only) | Wallpaper and personalization |
As you can see from the table, the combination of methods is the best result. Using only one method can leave loopholes for information leakage. For example, if you turn off the preview, you can forget about the Always On Display settings.
Owners of older Redmi or Poco models with a simplified version of MIUI may not be available Always On Display, but global notification settings are present in almost all current firmware, making the basic instruction universal for most devices of the brand.
💡
The combination of global content hiding and customization of mission-critical applications ensures maximum data protection without losing the functionality of the smartphone.
Display problems and their solution
Sometimes users are faced with a situation where the settings are applied, but the text of the messages is still displayed, this can be caused by aggressive battery optimization or errors in the operation of a particular application. First of all, check if the application has been added to the list of energy saving exceptions -> Battery -> Application management.
Another common reason is the work of “Advanced Notifications” in the messengers themselves. For example, WhatsApp can duplicate a notification through its service, ignoring the system settings of MIUI. In this case, you need to go to the settings of WhatsApp itself, select the “Notifications” section and disable the preview or high-priority notifications.
If the problem is systemic and is seen in all applications, try clearing the Notification Center or Security cache. To do this, go to Settings -> Apps -> All Apps, find the system application and click Clear Cache. This will not delete your data, but reset the interface display settings.
💡
If you still see text after all the settings, try changing the theme to the standard one. Third-party themes often have their own lock screen scripts that may conflict with the system privacy settings.
In rare cases, the bug may be associated with a particular firmware version. If you are sure that the settings are correct but the result is not, check for system updates. Xiaomi engineers regularly release patches that correct such errors in the interface.
Additional Security Measures for Locking Screen
Hiding notification text is just one layer of protection. For complete security, it's also recommended that you set up sensitive data in the notification curtain. Even if the text is hidden, the app icon itself can tell you a lot. MIUI has a feature called "Hide notification contents on the lock screen," which we've already discussed, but it's also worth paying attention to the possibility of hiding application icons.
To do this, some versions of MIUI (especially in Chinese builds or through the Security app) have the Hiding Apps feature available. While it works differently, the logic is the same: important data should not be horny. It is also useful to set up automatic locking of the screen after a minimum period of time (for example, 15 or 30 seconds) to make the screen go out faster.
Using fingerprint or face unlock speeds up access to the device, which indirectly helps privacy: you remove the phone from the eyes of others faster after reading the notification.
⚠️ Warning: Don't rely on software-based text hiding, physical screen protection (shield protection) and no phone in the sight of outsiders are basic digital hygiene rules that have never been repealed.
A comprehensive approach that includes system settings, apps and usage habits will make you feel confident in any situation, and your smartphone will become a truly personal device, not an open book for others.
