The modern smartphone, especially the popular Xiaomi Redmi 9, has become the center of digital life, but along with useful features, it brings constant information noise. Endless pop-ups, incoming messages and intrusive promotional offers from applications can be seriously annoying and distracting from important things. Many owners of devices based on the shell MIUI face the need to fine-tune the system to regain control of the gadget.
In this article, we will take a look at all the ways you can block alerts, not only how to silence the sound, but also how to completely remove the visual banners that block the screen. Competent system setting allows you to use Redmi 9 as efficiently as possible, leaving only really important messages.
The MIUI Alert Management process has its own unique features that differentiate it from pure Android. Understanding the logic of security and optimizer applications will help you avoid the phone starting to make noise again after updating or installing a new program.
Basic setting of the global “Do Not Disturb” regime
The fastest way to temporarily silence all sounds and vibrations on your Xiaomi Redmi 9 is to use Do Not Disturb mode. This feature not only turns off the sound, it intelligently filters incoming calls and messages, allowing only selected contacts or repeat calls to be activated through the control panel, swiping your finger from the top edge of the screen down.
However, standard on-boarding may not be flexible enough for everyday use. For a deeper setup, go to Settings → Sound and Vibration → Don’t Disturb. Here you can set a schedule to automatically go quiet at night or while you’re working, which is especially important for battery and mental comfort.
⚠️ Warning: In Do Not Disturb mode, the alarms on Redmi 9 continue to work by default, but it’s best to recheck the alarm settings to make sure it’s not labeled as “silent».
It's important to distinguish between a complete shutdown and a do-not-disturb mode. If your goal is total silence without exceptions, you'd better use a volume slider. But if you want to skip a call from a loved one in an emergency, the settings of exceptions to the mode settings will be the best choice. MIUI allows you to create a list of favorite contacts whose calls will take place even when the silence is active.
Managing Notifications for Specific Applications
The main source of visual and audio debris is third-party apps that you install from Google Play or GetApps. Every new app on Redmi 9 gets permission to display notifications by default, leading to chaos in the status curtain. To clean up the order, you need to manage permissions for each application individually through system settings.
Go to Settings → Notifications and Status bar → Notifications Management. This is a complete list of all installed programs. When you choose a specific application, such as a game or news aggregator, you get access to a detailed menu where you can turn off sound, vibration, display on the lock screen and even prevent the icon from appearing on the app icon.
- 🔇 Sound: Completely disabling audio messages.
- 📳 Vibration: Disabling tactile response when data is received.
- 🚫 Banners: Banning pop-ups on top of other apps.
- 🔒 Lock screen: Hiding the contents of the message when the phone is lying screen up.
Special attention should be paid to categorizing notifications within apps. Modern versions of MIUI allow you to divide alerts from one application into types: “Messages”, “Marketing”, “Updates”. By disabling the category “Marketing” for the clothing store, you will stop receiving ads, but continue to see the status of orders delivery. This is a fine-tuning that makes using Redmi 9 more comfortable.
☑️ Checking the application settings
Disabling system notifications and MIUI advertising
The MIUI shell installed on the Xiaomi Redmi 9 is known for its built-in services that can generate its own notifications, which can be recommendations from the Security app, tips from the Explorer, or promotional offers from the system browser. Fortunately, most of these noise sources can and should be manually disabled.
To start, you go to the Security app, click on the three dots in the top right corner, and select Settings, and you have to find the "Get References" item and deactivate it, and that removes pop-ups with tips for cleaning up memory or speeding up the system, which often appear at the most inopportune moment.
⚠️ Warning: Disabling system recommendations does not affect antivirus or fraud protection, so the security of your Redmi 9 will not be compromised.
You can go through other system applications, and Explorer, Music, and Video also have settings that contain ads and recommendations, and Mi Browser needs to turn off push notifications from news feeds, which are often automatically loaded, and cleaning these settings reduces the load on the processor and RAM of the device.
| System application | Where to look for settings | What to turn off |
|---|---|---|
| Security | Menu (3 points) → Settings | Receive recommendations |
| Downloads. | Menu (3 points) → Settings | Showing notifications |
| Conductor | Menu → Settings → About the application | Recommendations, News |
| Mi video | Profile → Settings | Push notifications |
After doing this, your Xiaomi will be much calmer, system services will stop imposing content that you don’t need, and you will be able to focus on the main tasks. Regularly checking for updates to system applications also helps, as new versions sometimes change the location of privacy switches.
Setting up the lock screen and notification curtain
Even if the sound is turned off, constant visual pops on a locked screen can be annoying. Redmi 9 has the flexibility to adjust what information is displayed when the phone is in sleep mode, not only a matter of comfort, but also an important aspect of protecting personal correspondence from prying eyes.
From the Settings menu → Notifications and Status bar → Notification format (or similar item in your version of MIUI) you can choose the display style. Choose the option “No text” or “Hide content” so that only the name of the application, not the text of the message, is displayed on the lock screen.
How to remove application icons from the lock screen?
Also worth noting is the Notification Curtain, which can prevent certain apps from appearing in the drop-down list in the Notifications and Status Settings, such as games or news aggregators that can be hidden from the curtain by leaving only messengers and calls, which will make the notification bar clean and informative.
Remember the Pocket Mode feature, which prevents accidental taps in your pocket, can sometimes lock the screen too aggressively, creating the illusion of freezing notifications, check the proximity sensor settings in the Lock and Protection section if you notice strange behavior of the screen when messages arrive.
Blocking Intrusive Advertising in Apps
One of the main reasons for wanting to disable notifications on Xiaomi Redmi 9 is pop-up ads, often in the form of push notifications from obscure applications or even as windows on top of other programs, and you need to combat this in a comprehensive manner using built-in tools.
First of all, use the built-in ad blocker in your browser and system applications. Go to Settings → Passwords and Security → Access to Personal Data (or “Authorization and Security” in older versions). Find the Ad Services section and disable ad personalization. This will not remove ads completely, but will make them less intrusive and frequent.
- 🛡️ MIUI Optimization: In the hidden developer menu, you can find a switch that affects the operation of system services, but be careful when changing it.
- 📉 Background activity limit: Limit apps from the background so they can’t initiate ads when you’re not using them.
- 🚫 Removing questionable software: Often the source of advertising is apps installed randomly. Check the list of installed programs and remove all unknowns.
If the ad continues to appear as separate windows, check which app has a resolution "Above other apps." In the Settings menu → Apps → Permissions → On top of other apps, disable this right for all suspicious programs, leaving it only for navigators and instant messengers where it is really necessary.
💡
Use the “Second Space” feature on Redmi 9 to install suspicious apps, which will isolate them from the main system and prevent them from accessing your personal notifications and contacts.
Use of third-party applications and automation
For advanced Redmi 9 users, there are options to automate notification management processes. Standard MIUI tools are powerful, but sometimes a more complex scenario is required, such as completely shutting down the Internet and notifications when a particular application is launched or at a given time.
Automation applications like MacroDroid or Tasker allow you to create complex chains of action. You can customize the script: If Bluetooth headphones are connected, → switch on the "Do Not Disturb" mode» → Turn off the vibration. These macros make the control of the phone almost invisible to the user.
⚠️ Note: When installing automation applications on Xiaomi, be sure to issue them all the requested permissions and remove restrictions on working in the background, otherwise the system will “kill” the process and the script will not work.
There are also specialized notification blockers that operate on a filter-like basis, which intercept all incoming messages and show them only if they meet a specified criteria (e.g., contain the keyword “Urgent” or from a specific contact), which is a radical but very effective way to combat information noise.
However, using third-party software, remember about data security. Trust only trusted developers with a good reputation in Google Play. Xiaomi built-in tools in most cases fully cover the needs of the average user, and resort to third-party solutions is only necessary if there are specific requirements.
💡
The combination of built-in MIUI settings and competent application resolution management allows you to completely eliminate visual and sound noise without installing additional software.
