Xiaomi smartphone owners often face intrusive pop-ups that overlap content or suddenly appear on the desktop. On the Redmi 9 model running the MIUI shell, this problem is especially acute due to the aggressive policy of monetizing free devices.
Completely eliminating irritants requires a comprehensive approach, as traffic sources can be different from embedded MSA services to malware. In this guide, we will discuss proven methods that will help restore the comfort of using a gadget. System advertising and viral banners require different methods of combating, so it is important to correctly identify the problem.
Many users mistakenly believe that the only way to get rid of notifications is to buy a global version of firmware or flash it. However, in most cases, it is enough to correctly configure the hidden parameters of the system.
Disabling MIUI system advertising
The first step is to deactivate the built-in MIUI System Ads (msa), which is responsible for collecting data and displaying banners in standard utilities, a process that does not require root rights, but requires care when switching toggles. On some firmware versions, the system can ask for confirmation of action several times, simulating a connection error.
First, you need to go to the security settings menu, find password and security, and go to Access to Personal Data, and then you can find the msa app and turn off the access slider, and the system will warn you of the possible consequences, but it's safe for the user.
☑️ Audit of system services
After disabling msa, it is also recommended to limit the Mi Daemon service, which often works in tandem with an advertising module, this action will reduce the background activity of processes that consume battery power. MIUI.
💡
If the slider of the msa service is not activated the first time, wait 10 seconds and try again.The system deliberately creates a delay so that the user does not turn off the service accidentally or in a fit of emotion.
Set up personalized recommendations
The second source of intrusive content is personalized recommendations that are built into standard Xiaomi apps, which can be displayed in folders on the desktop, in the Music app, in the Video app, and even in the File Manager, and these settings are scattered across different menus, so you have to turn them off separately in each application.
To remove banners from your desktop folders, press and hold your finger on the blank spot of the screen, then select settings. Find the Recommendation switch and turn it off. This will remove the advertising icons that the system suggests you download based on your activity.
- 📱 For Security: Open the app, click on the settings gear and turn off the "Get recommendations" item».
- 🎵 For Music app: go to settings, select “Advanced Settings” and uncheck the box from “Show Advertising».
- 📁 For Explorer: in the settings menu, find the About section and disable the Recommendations option».
⚠️ Note: In some updates MIUI The ad-disabled point in standard apps can be hidden. If you can't see the switch, try changing the region in the main phone settings to "India" or "USA," perform the disablement, and then return your region.
Also, remember to check the settings of the Themes app, which is where you often get notifications about new paid or advertising wallpapers, go to the user profile in the lower right corner and turn off all personalization notifications.
Blocking advertising in the browser and applications
If the ads appear while surfing the Internet or in third-party applications, the most effective way to combat this is to use a private DNS. This method blocks requests to known ad servers at the network level without requiring the installation of additional software, which is especially true for Redmi 9, which may not have excessive performance for heavy blockers.
Go to Settings → Connection and Sharing → Private DNS. Select the DNS Host Name mode and type in the address: dns.adguard.com. Once saved, the phone will reconnect to the network, and most banner ads in browsers and games will stop loading.
What to do if the DNS is not working?
For browsers, it is also recommended to install a blocker extension if you use Chrome or Yandex. Mobile Chrome can enable the built-in but hidden pop-up blocking feature in the privacy settings. DNS-The filter is much more efficient for the whole device.
| Locking method | Efficiency | Impact on the battery | Difficulty setting up |
|---|---|---|---|
| Disconnecting msa | High (systemic) | Reduces the cost | Low. |
| Private DNS | Very high. | It doesn't. | Low. |
| Blocking applications | Maximum | Increases spending | Medium |
Search and Remove Viral Advertising
The situation when advertising windows fly to the desktop without running applications indicates the presence of malware. Often such programs are disguised as useful utilities: flashlights, scanners. QR-On Redmi 9, these viruses can be embedded deep into the system, requiring manual removal.
Go to Settings → Apps → All apps. Carefully review the list for programs without a name or with a transparent icon. Often viruses hide at the bottom or at the top of the list. If you find a suspicious item without an icon, delete it immediately.
If you can't delete the application through the standard menu (the "Delete" button is inactive), then the virus has acquired device administrator rights.
- 🔒 Go to Settings. → Password and security → Confidentiality → Special facilities.
- 🔍 Find a suspicious application in the list and take away its rights.
- 🗑️ Then go back to the app menu and delete it.
⚠️ Warning: If a virus blocks your phone's settings, try running the device in Safe Mode. To do this, press the off button, and when the menu appears, press and hold the "Stop" option until the prompt appears to go to Safe Mode. In this mode, only system applications work, which will remove the malware.
Disabling Notifications from Websites
A common reason for the emergence of “advertising” is the permissions that users themselves give to sites in the browser. When you visit a news or entertainment portal, you may accidentally click “Allow notifications”, after which the site began to send spam even when the browser is closed, it is not a virus, but a legitimate but intrusive feature of web technologies.
To fix this, open a browser (like Chrome), click three dots in the corner and select Settings. Go to Site Settings → Notifications. Here you will see a list of all resources that have access to push notifications. Ruthlessly delete or block all unfamiliar addresses.
A similar procedure should be carried out for other browsers installed on your Redmi. 9. Often users forget about the built-in Mi Browser browser, which by default can be configured for aggressive news.-push notifications from news partners.
💡
Spam notifications from sites are not a virus, so antivirus will not find them, and the solution lies solely in the permission settings of the specific browser through which you visited the sites.
Use of third-party cleaning tools
If manual methods seem too complex or do not give the full result, you can use specialized utilities. However, be careful: many "cleaners" are the source of advertising themselves, it is better to use proven solutions with open source or from well-known vendors.
One of the most effective tools is the AdGuard app, which works as a local app. VPN-filter, passing all traffic through itself and cutting out advertising requests. APK-file from the official site, as in Google Play versions with full functionality are often stripped down.
Also worth considering is the possibility of installing an alternative launcher, such as Nova Launcher. standard shell MIUI has deep integration with advertising services. Third-party launcher will replace the desktop and menu, completely eliminating the possibility of advertising widgets and recommendations in folders from Xiaomi.
