Xiaomi smartphone owners often face a situation where, after a system update or reset, the device stops showing incoming messages while the screen is off. 10S This is especially important given the quality of AMOLED-It's a display that allows you to implement Always On Display, but the standard energy saving algorithms. MIUI can aggressively block the background activity of applications, preventing timely receipt of information.
Understanding how the MIUI notification system works is the first step to solving the problem. Xiaomi’s security system is designed to maximize battery life, but sometimes it comes at the expense of functionality. You need to manually check multiple levels of settings to ensure that no important message is missed.
In this guide, we will look at all stages of configuration, from basic switches in the settings menu to fine-tuning with specific application permissions. We will also touch on the topic of AOD (Always On Display), which is directly related to the display of content on a locked screen.
Basic setting of notification display
The first thing to do is to make sure that the global settings allow content to be displayed on a locked screen, and often after a firmware update, these settings are reset to the default value that hides the text of messages for privacy purposes.
Go to Settings → Notifications and Status bar → Lock screen. This is the master switch that activates the alert display. If it is turned off, no other manipulations will produce the desired result. Make sure that the slider is in the active position.
- 🔘 Show notifications: the main switchboard that allows the system to output allerts.
- 🔒 Format: Choice between the full text of a message or simply the name of an application.
- 📱 Style: customize the appearance of icons on a locked screen.
⚠️ Note: If you select Hide Content, only the name of the app (e.g., Telegram) will appear on the lock screen, but the text will not be visible until the device is unlocked.
You also need to check the settings for specific notification categories, because Xiaomi has the flexibility to set priorities, for example, calls can always be displayed, and messages from games can only be displayed when the device is unlocked, which helps to avoid visual noise and saves the battery.
Configuring permissions for specific applications
Even if global settings are active, individual applications may be restricted. In MIUI, every application goes through a strict permission filter. If the messenger is not authorized to display over other windows or work in the background, notifications will not come.
To set up, go to Settings → Apps → All apps. Find the right messenger (like WhatsApp or Viber) in the list and click on it. You are interested in Notifications. Here you need to make sure that the Allow Notifications switch is activated.
Extended settings are also available within this menu:
- 🔔 Audible alert: will sound be issued upon arrival.
- 💡 Light indicator: flashing with an LED (if supported by a model).
- 🖥️ On the lock screen: a separate switch specifically for the locked state.
- 📢 In the curtain: display in the notification panel.
⚠️ Note: In some versions MIUI There's a separate "Important Notifications" switchboard, and if it's disabled, the system can deem messages from this app as not a priority and not wake the screen.
Pay special attention to the category "Other Notifications", often service messages or delivery notifications that may be hidden by default, check all available categories within the settings of a particular application to ensure that nothing is missed.
Battery optimization and background work
The most common reason for missing notifications on the Xiaomi Note 10S is aggressive battery optimization.The system automatically freezes apps it believes are not being used to save charge, which causes the messenger to be unable to connect to the server and receive a new message until you open it again.
To fix this, you need to add important applications to exceptions. Go to Settings → Battery and Performance (or simply “Battery”). Find the item related to saving application energy. You need to select the “No Limits” mode for mission-critical programs.
An alternative way through the application menu is Settings → Apps → All Apps → [Your App] → Battery. Here select No Limits. This will prevent the system from killing the application process in the background.
☑️ Energy conservation verification
It is also worth disabling AutoRun for unnecessary programs, but for instant messengers, autorupture is better left on so that they start immediately after the phone is turned on. Autoruption control is in the Security application → Permissions → Autorup.
Always on Display (AOD)
The Xiaomi Note 10S features a screen that supports Always On Display, which allows you to display the hours, date and notification icons even when the screen is formally off, and it's not just a picture, but a full-fledged display mode with minimal power consumption.
To activate, go to Settings → Always screen on and lock. Here you can choose the style of the watch and adjust the schedule. Importantly, AOD notifications can only be displayed as icons to avoid burning out pixels and saving energy.
| Parameter | Description | Impact on the battery |
|---|---|---|
| Always mode. | The screen is on 24/7 | High. |
| Scheduled. | Works at the specified hours | Average. |
| 10 seconds. | Included upon receipt of notification | Low. |
| When lifted | Activated by motion sensor | Low. |
The 10 seconds mode is the most optimal for most users, and the screen lights up when a new message arrives, shows the icon, and goes out after a given period of time, so you don't miss the event, but you don't waste the charge.
Why can't AOD work?
Problems with third-party launchers and themes
Sometimes the standard MIUI interface is replaced by a third-party launcher or a heavy theme is installed from the Themes store.These elements may conflict with the standard mechanism for displaying notifications on the lock screen.
If you use a custom theme, try switching to a standard theme of "Classic" or "Default." Often, problems with displaying fonts or icons on a locked screen are solved by returning to factory design.
If you use a third-party launcher (Nova, Lawnchair, etc.), make sure it is given all necessary permissions to block the screen and access notifications. However, the regular MIUI launcher always guarantees the best compatibility with all system functions, including the lock screen.
⚠️ Warning: Some themes may completely hide the status bar or change the lock area, making notifications physically unable to appear in the designated location.
It’s also worth checking the special features settings. If you have disabled features enabled, they can change the behavior of the lock screen. Check Settings → Advanced Settings → Special features and make sure there are no active scripts blocking the screen.
Additional settings and resetting settings
If none of the above methods worked, there may have been a software glitch in the system. MIUI has a hidden notification debugging menu, but it is safer for the average user to reset notification settings or check system integrity.
Try clearing the cache of the Settings system app and the Security app. This won't delete your personal data, but will update your configuration files. Go to Settings → Apps → All Apps → Settings → Memory → Clear.
In extreme cases, if the problem has appeared after the update, it can help to reset all settings to factory.Be sure to make a full backup of the data to the Mi Cloud cloud or to your computer before that.
💡
A comprehensive check of all levels of settings (system, application, battery) solves 99% of the notification problems on Xiaomi.
Don’t forget to update apps regularly through Google Play or GetApps. Messenger developers often release patches that improve compatibility with newer versions of Android and manufacturers’ shells.
