Modern Xiaomi smartphones running on the shells of MIUI or the new HyperOS are often overloaded with redundant information. Endless pop-ups, advertising in system applications and intrusive offers from installed games create a sense of chaos. It becomes difficult for the user to focus on important messages from messengers or work chats when the screen is constantly lit up by extraneous noise.
But the Android operating system provides powerful tools to manage these data streams, and by setting it right, not only removes the annoying sound, but also completely prevents a particular app from bothering you at a certain time, which is critical to keeping your battery power and boosting your personal productivity throughout the day.
In this guide, we will break down all the available blocking methods. You will learn to distinguish system notifications from custom ones, disable ads in standard Xiaomi utilities, and configure Do Not Disturb profiles for maximum comfort.
Basic setting through the notification center
The fastest way to stop a message from a particular application is to do so directly from the drop-down menu. When a new alert appears on the screen, don't rush to swipe it. A long tap on the notification text will open a context menu where you can instantly jump to the source settings.
So here you'll see the All Notifications switch, and if you turn it off, the app will no longer be able to output information to the lock screen or the curtain, and this action doesn't delete the app, it only limits its ability to get your attention.
💡
Use the 15-minute shutdown right in the curtain if you need to focus temporarily, but you’re afraid to miss an important call later.
It is worth noting that some system services may ignore standard prohibitions if they are given extended rights, and in such cases, you need to go to the deep settings menu, which will be discussed in the next sections of the article.
Managing permissions in system settings
To control digital noise, you need to go to the main configuration menu of your smartphone. The path to the desired parameters may vary slightly depending on the version of the shell, but the logic remains the same for all Redmi and Poco devices.
Go to Settings → Notifications and Status bar → Notification management. This is a complete list of all installed programs. When you choose a particular application, you are placed in a detailed menu where you can flexibly customize the behavior of the system.
- 🔕 Prohibit notifications: A complete block of any signals from the selected object.
- 🔇 No sound: Visual display remains, but audio and vibration signal disabled.
- 📉 Importance: Priority adjustment to hide content on the lock screen.
- 🚫 Floating notifications: Turning off pop-ups on top of other apps.
Note the Advertising category: In newer versions of MIUI, the system automatically classifies some messages as advertising and can hide them by default, and check if something important to you has hit them.
☑️ Checking the application settings
It is important to distinguish between channel types within an app, for example, you may receive confirmation codes and promotional mailings from a bank, and in the management menu you can only turn off the Marketing channel, while keeping the Security channel active.
Disabling Advertising in Xiaomi System Applications
One of the most common reasons for Xiaomi users’ irritation is the built-in advertising in standard utilities. These are not ordinary notifications, but rather intrusive recommendations from the MSA service (MIUI System Ads), which require a separate approach to disabling.
To remove ads in apps like Explorer, Music, Themes, or Downloads, you need to turn off ad personalization. Go to Settings → Passwords & Security → Access to Personal Data (or Privacy) Find in the msa list and turn off the switchboard. The system will ask you to wait 10 seconds, after which you need to confirm the action.
What if the MSA doesn’t shut down the first time?
The Themes app requires special attention. Even after general settings, it can show banners. Open "Themes", click on the profile, then click on the settings icon and find "Receive recommendations", then deactivate it.
The Download Manager process is similar: open the app, click three dots in the corner, select Settings, and remove the tick from Get Recommendations, which will make the file download process clean and free of visual debris.
Use of the "Do Not Disturb" mode
When you need absolute silence, such as during a sleep or an important meeting, it is best to use a special mode of operation of the smartphone, which differs from a simple silent mode in that it allows you to create a “white list” of contacts, calls from which will still pass.
You can activate the function through the quick settings curtain or through the Settings menu → Sound and vibration → Do not disturb. This setup schedule automatically turns on, eliminating the need to turn on the mode every night.
| Parameter | Description of function | Recommended value |
|---|---|---|
| Media sound | Silence video and games | Off. |
| Alarm clock | Allows the alarm clock to sound | Included. |
| Repeated calls | Missing the second call in 3 minutes | Included (for emergency) |
| Visual effects | Screen flickering when reporting | Off. |
In this mode, the smartphone screen does not light up when new messages arrive, and the application icons do not appear in the status bar, which helps to completely abstract from the digital world, keeping in touch with only the closest people.
Remember that this mode may not work with calendar reminders unless you set exceptions. Carefully review the list of permitted events before activating a long period of silence.
Blocking pop-up windows in the browser
Often, the source of chaotic notifications is not the application, but the website visited through the browser, users accidentally allow sites to send push notifications, after which ads or news constantly pop up on the screen.
To eliminate this, you need to go to your browser settings (Chrome, Mi Browser or another). Go to the Site Settings section → Notifications. Here you will see a list of all the resources that have been given permission to display messages.
⚠️ Note: If you see unfamiliar sites with names like «Winners2026» or System Update, delete them immediately or deny access, a sure sign that you have encountered advertising spam.
The best strategy is to set a global ban on notification requests. In your browser settings, find the "Request Permission" option and switch it to "Block" mode. Now no site can request access to your notification curtain without your knowledge.
It is also recommended to periodically clean the cache and browser data, which will not only free up space in memory, but also reset some temporary permissions that may have been obtained accidentally while surfing.
Specificity of the work of background processes
It’s important to understand the difference between turning off notifications and stopping an app. If you stop a messenger like Telegram or WhatsApp from showing notifications, messages will still come to the server, but you won’t know about them until you open the app yourself.
Android aggressively manages memory, especially on devices with a MIUI shell. If the app falls asleep too deeply, notifications may come with a delay. To avoid this for important contacts, use the "No Limits" feature in the battery settings.
Go to Settings → Applications → All Apps → [Your App] → Battery. Select No Limits mode. This ensures that the system won’t “kill” the application process in the background, and you’ll get data on time even if notifications for other programs are disabled.
💡
Disabling notifications is not the same as deleting an application. You can always return settings back if you stop receiving important codes or messages.
Some games and stores have their own internal pus settings, and even if you let the system show notifications, the app itself can tick "Do not show news." Check the settings there too.
