How to permanently remove the browser that opens on Xiaomi: reasons and solutions

You take a Xiaomi smartphone out of your pocket and you have a browser on your screen with ads, news or a suspicious site? This problem is familiar to many owners of devices on MIUI, the brand's brand shell. Automatically launching a browser is not only annoying, it consumes traffic, battery power and can be a sign of viral activity. 80% of the time, it is not malware that is to blame, but aggressive system settings or Xiaomi advertising services.

In this article, we will discuss all possible causes of spontaneous opening of the browser, from standard MIUI functions to hidden advertising mechanisms. You will learn how to disable automatic start through system settings, remove unnecessary services and even block problem processes at the Android level. The instructions are relevant for all modern models, from the Redmi Note 12 to the flagship Xiaomi 14 Ultra, as well as POCO devices based on MIUI 12-14.

Why the browser opens itself: 6 main reasons

Before you start to solve the problem, it is important to understand the source of the problem. In Xiaomi smartphones, automatic browser launch can be associated with:

• 🔍 Advertising notices from MIUI — the system shows promotional content through the browser (often found in regional firmware for India, Indonesia, Russia).
• 📱 Quick Links – Built-in mechanism MIUI, It analyzes your actions and offers “useful” websites.
• 🔄 System or application updates – after the update MIUI Sometimes privacy settings are reset.
• 📊 Xiaomi analytics services (msa, MiuiDaemon) – collect user data and can initialize the launch of the browser.
• 🛠️ Firmware errors - bugs in specific versions MIUI 13.0.4–13.0.6 (e.g., for Redmi Note 11) resulted in spontaneous link opening.

The most common reason is MIUI advertising mechanisms, and even if you haven't installed suspicious apps, it can show promotional content through Mi Browser or Google Chrome, for example, after connecting to Wi-Fi at hotels or airports.

⚠️ Warning: If your browser opens from suspicious sites (gambling, adult content, phishing), immediately check your device for viruses. This may be a sign of a Trojan that is stealing data.

3. Return to the main settings menu and go to Settings → Additional → Special Opportunities → Advertising Notifications.
4. Turn off the “Show Advertising Notices” slider.

For complete removal of advertising, it is also recommended:

• 📵 Remove the Mi Video app (if not used) – it often shows promos through the browser.

Method 6: Fastboot Fastboot Fastboot Fastboot (for advanced ones)

If the browser opens even after a reset, it's either corrupted firmware or malware at the system level, and then clean flashing through Fastboot mode will help.
