How to permanently disable advertising on Xiaomi Poco X3 NFC: lock screen, menu and applications

Advertising on Xiaomi smartphones is one of the most annoying features of MIUI firmware. Poco X3 NFC owners encounter banners on the lock screen, in the settings menu, and sometimes even in system notifications. The manufacturer has integrated ad modules so deeply that standard shutdown through settings often works incompletely or resets after updates.

In this article, we will discuss all the current ways to remove advertising on Poco. X3 NFC — From basic settings to advanced methods using ADB We will pay special attention to hidden advertising services that continue to work even after the main options in Settings are turned off. → Advertising.

Importantly, the methods vary in complexity and risk. Let's start with the safest ones and move on to the radical ones, which require unlocking the bootloader or the superuser rights. If you're not ready to experiment, use the first three ways, they won't violate the warranty or cause data loss.

Basic MIUI settings: what can be turned off without risks

The first step is to check the standard options in firmware. Xiaomi has added the ability to partially control ads, but many users are unaware of all the hidden switches.

Open Settings → Memory → Clean up and disable the "Recommendations" item. This will remove the banners with cleaning suggestions at the bottom of the screen.

• 📱 Settings → Lock screen → Turn off "Receive recommendations" and "Show ads" (if items are available).
• 🔍 Settings → Annexes → Application management → Mi Services. → "Show notifications" (block the).
• 🛠️ Settings → The phone. → Version. MIUI → Tap 7 times on the version to activate the developer mode, then return to Settings → Additionally. → For developers and disable "Debugging by" USB" (if you don't use).

These actions will remove up to 60% of ads, but banners in system applications (Calendar, Weather, Themes) will remain.

2. disabling advertising through MIUI Optimization (no root)

The hidden MIUI Optimization service is responsible for personalized recommendations and banner ads, and can be deactivated via ADB — it doesn't require superuser rights, but it requires a computer.

Instructions:

1. Download Google’s Platform Tools and unpack it into a folder.
2. On your phone, activate the developer mode (as in the previous section) and enable debugging over USB.
3. Connect Poco X3 NFC to your PC, open the command line in the folder with ADB and execute: adb shell pm disable-user --user 0 com.miui.systemAdSolution

After the device is restarted, the ads in the system menu and on the lock screen will disappear. If the banners remain, follow additional commands:

adb shell pm disable-user --user 0 com.xiaomi.mipicks


adb shell pm disable-user --user 0 com.miui.analytics

3. Removal of Advertising in Xiaomi Apps (Manual Method)

Some system applications (Themes, Calendar, Music) have built-in advertising modules that do not turn off globally.

List of "infected" applications and ways to clean them:

If the ads remain after these actions, then the application receives banners through the Xiaomi server, in which case only removing the application (requires root) or replacing it with an alternative from Google Play will help.

4. Radical methods: firmware without advertising (for experienced)

If the standard methods do not help, there are two options:

1. Install custom firmware (e.g. Pixel Experience or LineageOS).
2. Reflash the phone to the global version of MIUI for the EEA region, where advertising is legally disabled.

Benefits and risks:

• ✅ Complete removal of ads and bloatware (unnecessary system applications).
• ✅ Opportunity to choose firmware with current security updates.
• ⚠️ Loss of warranty (when unlocking the bootloader).
• ⚠️ Risk of "brika" (turning the phone into a "brick") with firmware errors.

For the Poco X3 NFC, we recommend the firmware xiaomi.eu, which is the official MIUI, but with remote advertising and optimizations.

1. Unlock the bootloader through the official Xiaomi tool.
2. Download the firmware xiaomi.eu for surya (codename Poco) X3 NFC) s 💡Before firmware, back up the data through Settings → Additionally. → Backup. Save a copy on PC — recovery from MIUI Cloud may not work after changing the firmware. 5.

To completely remove banners, combine it with disabling services through the Internet.
