If you've ever looked at the installed list on your Xiaomi smartphone, you've probably noticed a strange system software called MiWebView, which doesn't have a desktop shortcut, doesn't show up on the app menu, but it takes up space in memory and sometimes appears on the active process list. What is it, why does the manufacturer need it, and most importantly, can it be removed without affecting the phone?
In this article, we will discuss in detail what MiWebView is, how it is related to the corporate shell. MIUI, You will also learn the risks of removing this component, how to properly disable or deactivate it if it interferes, and what alternative solutions exist to optimize the smartphone. We will pay special attention to security issues โ not all system applications can be removed without consequences.
Spoiler: In most cases, MiWebView isn't critical to the phone's performance, but removing it can lead to problems displaying web content in some Xiaomi system menus and apps.However, there are ways to minimize its impact on performance.Read on to find out all the nuances.
What is MiWebView and why is it necessary to use it? MIUI
MiWebView is a system component of the shell MIUI, The one that's responsible for displaying web content inside Xiaomi applications is basically a modified version of the standard Android System WebView, adapted to the needs of proprietary software:
- ๐ Ensuring the operation of built-in browser windows in system applications (for example, in Settings) โ The phone. โ Software updates that display web pages with update information).
- ๐ฑ Support for web views in branded utilities such as Mi Community, Mi Video, Mi Browser and others.
- ๐ Link processing and web preview in some menus (for example, when clicking on a link in a notification).
- ๐ก๏ธ Integration with Xiaomi services for displaying ads, promotional materials and analytics (yes, this is also part of its features).
It's important to understand that MiWebView is not a full-fledged browser, but rather an engine for displaying web content within other applications, for example, when you open the Help section in your phone's settings and see a web page there, it works through MiWebView, not through Chrome or another browser.
Technically, this app is based on the open source Chromium project, but with proprietary improvements from Xiaomi. MIUI (Starting with version 9 and above) and updated with firmware or through Google Play (if supported by the model).
Can you delete MiWebView without phone consequences?
The short answer is: technically yes, but not recommended. The long answer requires understanding the risks. Let's figure out what happens if you remove or disable this component:
| Action. | Possible consequences | Risk to the system |
|---|---|---|
| Complete removal through ADB | Some system menus will no longer display web content (e.g., updates, help, promotional materials). | Medium. |
| Disconnection through settings | Temporary malfunctions of applications that use web views (for example, Mi Community may not open links). | Low. |
| Removal of updates | Recoil to the factory version, compatibility errors with new versions are possible MIUI. | Low. |
| Replacement with Android System WebView | Certain functions MIUI may not work properly (for example, branded widgets or advertising blocks). | Medium. |
The main problem is that some Xiaomi system applications are tightly tied to MiWebView, such as:
- ๐ข Notifications and Advertising: Some promotional materials and banners will no longer appear.
But the good news is that MiWebView isnโt critical for the basic operation of the phone, you can make calls, use instant messengers, run games and most third-party apps, but if youโre actively using Xiaomiโs branded services, deleting it can be a inconvenience.
โ ๏ธ Note: Some models (e.g. Redmi Note 10 Pro) POCO X3 Pro) deleting MiWebView may result in a cyclical system reboot. MIUI Check the integrity of system components at startup.Be sure to back up the data before deleting it!
How to safely disable or remove MiWebView: step-by-step instructions
If you do decide to get rid of this component, here are three proven ways, sorted by risk level (from the safest to the most radical).
Method 1: Disconnect via settings (without root)
The safest method, which requires no special knowledge, is suitable for most users:

- Reboot the phone.
โ ๏ธ Note: On some firmware, Xiaomi blocks removal of system applications through ADB. If you see a Failure error [DELETE_FAILED_INTERNAL_ERROR], So the manufacturer has banned this action from your model, and then you can only get root rights.
Method 3: Removal with root rights (for advanced)
The riskiest, but also the most effective method, requires unlocking the bootloader and installing Magisk or some other super-user solution.

MiWebView and Security: Does it Collect Your Data?
One of the most popular questions is, is MiWebView a spyware that collects personal data?
Technically, MiWebView is a web engine, not a standalone data-collection app, but it is integrated with Xiaomi services that can actually transfer some data to the company's servers.
- ๐ Usage Analytics: Xiaomi collects statistics on how users interact with web content in system applications (e.g., which links open, how much time they spend on pages). MIUI.
- ๐ข Targeted Ads: If you see personalized ads in the system menu (e.g. Settings) โ Recommendations), MiWebView may participate in its display, but the ads themselves are downloaded through other services (for example, com.miui.daemon).
- ๐ Access to Personal Data: The app has permissions to access the internet and stored files, but no read rights SMS, However, it may transmit information about your device (model, version) MIUI, region).
Xiaomi has come under fire for its data collection (for example, in 2020, the company was accused of transferring user information to servers in China), but after the scandals, Xiaomi made changes to its privacy policy and now offers users from the EU and other regions the ability to disable analytics collection.
If you are concerned about privacy, you can:
- Disable the collection of diagnostic data in Settings โ Memory. โ Privacy โ Diagnostics.
- Use a firewall (such as NetGuard or AFWall)+) to block MiWebView's access to the Internet.
- Install custom firmware without Xiaomi services (for example, LineageOS).
โ ๏ธ Note: Complete removal of MiWebView does not guarantee the termination of data collection. Other Xiaomi system applications (e.g. com.miui.analytics or com.xiaomi.midrop) are also involved in the transfer of information.
