Spam on smartphones Xiaomi Redmi is a problem that every third user faces. Advertising notifications, suspicious SMS, pop-up banners and background processes are not only annoying, but also slow down the devicedrain your battery, and in worst cases, steal personal data. Unlike the iPhone, where the ecosystem is closed, Android on Redmi (especially with firmware MIUI) often becomes a target for aggressive marketing and malware.

The reasons for the appearance of spam are varied: from pre-installed system applications (Mi Browser, GetApps, Mi Video) to third-party utilities downloaded from unverified sources. Even after resetting the settings, spam may return if its root is not addressed. In this guide we will look 7 working methods from basic to advanced, including hidden settings MIUI, working with ADB and alternative firmware. You will learn how to not only remove existing spam, but also prevent it from appearing in the future.

1. Identification of sources of spam on Redmi

Before you start cleaning, you need to understand what exactly infects your phone. Spam on Redmi is divided into three categories:

  • 📱 System spam - built-in applications Xiaomi (com.miui.systemAdSolution, com.xiaomi.midropthat show advertising even without your consent.
  • 📲 Third-party applications - apps from Google Play or APK files that load advertisements via push notifications.
  • 🦠 Malware - viruses, trojans or spyware modules masquerading as legitimate utilities (for example, "cleaners" memory").

To identify the culprit:

  1. Open Settings → Applications → Manage applications.
  2. Sort the list by Data usage — spam applications often consume traffic in the background.
  3. Check the section Notifications —all apps that send push messages are displayed there.
💡

If you see unfamiliar names in Chinese in the application list (for example, com.duokan.phone.remotecontroller), this is most likely malware. Do not delete it manually - first create a backup copy of your data.

Pay special attention to applications with rights Device Administrator (located in Settings → Passwords and Security). Viruses often request these rights to block their removal.
