Xiaomi Redmi 9 owners often face the problem of pre-installed apps that take up space in memory, consume battery power and display annoying advertising. Even after clicking "Delete" in the menu, many programs simply turn off, but do not disappear completely. Why is this happening?
The fact is that the manufacturer integrates part of the software into the system section /system/app, But there are legal ways to get rid of unnecessary services, from simply disabling through settings to deep cleaning with the help of ADB-In this article, we will discuss all current methods, including nuances for a particular Redmi model. 9 (codename lancelot, and explain how to avoid "bricking" the device.
Why you can’t just remove system applications
System applications on Xiaomi are divided into three categories:
- 🔹 Critical services – are responsible for the operation of Android (for example, com.android.phone for calls), their removal will lead to the inability to boot the system.
- 🔹 Xiaomi's proprietary utilities are miui.analytics, miui.daemon, miui.bugreport. You can delete, but this will turn off statistics collection and diagnostics.
- 🔹 Bloatware preinstalled – com.miui.player (Music), com.xiaomi.scanner (Scanner), advertising SDK. Removed safely.
The manufacturer blocks removal for two reasons:
- License agreements with partners (e.g. Facebook, Netflix) that require pre-installing their software.
- MIUI dependencies: Some applications are shell-related. For example, removing com.miui.gallery can break the camera's performance.
⚠️ Attention: Redmi 9 with firmware MIUI 12.5+ Attempting to delete com.lbe.security through the file manager will result in a reboot cycle!
Method 1: Disconnect via settings (without root)
The safest way to do this is to deactivate unnecessary applications, which won't free up memory, but will stop the background and remove icons from the menu.
Instructions for Redmi 9:
- Open Settings → Applications → Application Management.
- Slip three dots in the upper right corner and select Show all processes.
- Find the app you want (such as Mi Video or Mi Pay) and click on it.
- Select Disable → Disable the application (confirm the action).
List of applications that can be disabled without risk:
- 🎵 com.miui.player - Music
- 📺 com.miui.videoplayer - Video player
- 📊 com.miui.analytics – Xiaomi Analytics
- 🔍 com.xiaomi.scanner - Document scanner
- 💰 com.xiaomi.payment — Mi Pay
Make a backup copy of important data
Check the version of MIUI in Settings → About the phone
Battery charge of at least 50%
Do not disable system services with Android icon-->
⚠️ Warning: Disabling com.android.vending (Google Play Store) will make it impossible to update apps. Instead, uninstall updates for it in the same menu.
Method 2: Removal via ADB (without root but with PC)
ADB (Android Debug Bridge) is Google’s official tool for managing system packages. For Redmi 9, this method works on all versions of MIUI, but requires debugging over USB.
Step-by-step:
- Enable USB debugging: Settings → About Phone → MIUI Version (Tap 7 times) Settings → Additional → For Developers → Debugging on USB
- Connect the phone to the PC and confirm the debugging permission.
- Download ADB Tools and unpack it into a folder.
- Open the command line in this folder and type in: adb devices (the name of your device should appear).
- Get a list of all packages: adb shell pm list packages -f
- Remove unnecessary package (e.g. Mi Music): adb shell pm uninstall -k --user 0 com.miui.player
The keys of the pm uninstall command:
| Key key | Description |
|---|---|
| -k | Stores cache and application data (can be restored) |
| --user 0 | Removes only for the current user (does not affect system files) |
| -f | Forced removal (risky!) |
Disabled through settings
