Poco X3 NFC smartphone owners running MIUI shells often face intrusive advertising notifications, not a bug, but a feature of the company’s marketing policy that subsidizes the cost of devices by showing content to users. However, advertising on Xiaomi is not mandatory and can be completely removed without loss of warranty or functionality.
The process of disabling does not require root rights or complex system reflashing; you only need to follow the steps described below carefully and consistently disable the various services responsible for broadcasting banners. In this article, we will discuss everything from basic system settings to deeper manipulation of system applications.
Before you start, make sure your device is connected to a stable Wi-Fi network or mobile Internet. Some settings require real-time service status checks, and it is recommended to set aside about 15-20 minutes of free time to complete all the steps.
Disabling the MSA service, the main source of advertising
The main engine of the MIUI advertising campaign is the MSA (MIUI System Ads) system application, which analyzes your actions and loads banners into standard utilities, and the first and most important step is to deactivate it through authorization settings.
Go to the settings menu of your Poco X3 NFC and find the Passwords and Security section. Inside you will need to find the Access to Account Data or Authorization and Security item. In the list of system services that opens, find the msa line. Next to it will be a slider that needs to be put inactive.
The system will warn you that turning off this service may affect the operation of certain functions. Pay no attention to this and click the "Disable" button. Note that after pressing the button, a countdown timer (usually 10 seconds) will appear, and only after it expires will the confirmation button be available.

Set up personalization and advertising identifiers
In addition to the MSA service, the personalization mechanism is responsible for targeting ads, which collects your preferences to show more relevant (and annoying) ads, and disabling this option breaks the link between your behavior and the ad servers.
To do this, go back to the main password and security menu, and go to the privacy section and select Advertising Services or Special Advertising Opportunities, where you need to deactivate the Receive References option.
The menu also provides an ad reset function, so by clicking on the Reset Advertising ID button, you generate a new random code that resets the user's accumulated profile, which is useful periodically to maintain anonymity.
It's important to understand the difference between disabling a service and resetting an identifier. Resetting an identifier only resets the data, but does not prohibit the collection of new ones, so it's critical to turn off the recommendation slider, not just reset the ID.
