• 🔄 Returns after the phone is restarted.
• 🚨 Appear for no reason (e.g., System Optimization or Security Scanner»).

• 🔋 Battery Charging (if the cable is connected).
• 📶 Flight mode/traffic saving.
• 🔒 VPN or a protected connection.
• 🎵 Musical playback (even in the background).

However, if you see notifications with unknown names (such as com.android.system, Service Host or Cleaner) that lead to suspicious sites or ask for permission, this is a cause for concern, especially if they appeared after installing applications from third-party sources.

Reasons for permanent notification

There are several sources of “intrusive” alerts on Xiaomi, and let’s look at them in terms of their degree of danger, from the innocuous to the critical.

System notifications MIUI

MIUI — Xiaomi's proprietary shell, which actively uses notifications to inform the user:

• 🔄 «System optimization – appears after updates or prolonged use.
• 🛡️ «Security scanner – virus scanning (can work in the background).
• 📱 «Smart Help – Smartphone Use Tips (e.g., Connect Mi Account»).

2.Apps with aggressive advertising

Many free programs (especially from Google Play or third-party sources) show pop-up notifications with ads.

• 🎮 Games with a coin system (for example, Free Fire, PUBG Mobile).
• 📺 Applications for watching movies/series (for example, HD Cinema).
• 💰 Financial services (credits, cashback applications).

These notifications are often disguised as system notifications (e.g., “Your phone is infected!”) and lead to phishing sites, and they return even after the application has been removed, if it has managed to create a hidden service in the background.

• 🔗 Links to unknown sites (especially.xyz,.top domains).
• 💳 Requests to enter card details or login/password.
• 📱 Text in bad Russian ("Your device is in danger!»).

• 📎 Investments in SMS/The messengers ("You won the iPhone!»).
• 📥 APK-files from unverified sources.
• 🔌 Connection to infected USB-device.

Malware can not only show notifications, but also steal data, connect to paid ones. SMS-services or encrypt files (as in the case of ransomware viruses).
