Why is Xiaomi blocking APK installations from unknown sources?
The ban on installing apps outside of Google Play is not a whim of Xiaomi, but a security requirement inherent in Android at the system level.
🔹 Malware protection: Kaspersky says more than 30% APK-Third-party files contain potentially dangerous code, from ad viruses to spyware modules. MIUI 11 blocks such default settings to prevent infection of the device.
🔹 Compliance with Google's policy.As of 2018, Android 8.0+ Manufacturers are required to limit installation APK Xiaomi has met this requirement, but left a loophole for power users — the ability to selectively resolve individual applications.

However, the blockage creates inconvenience for:
- 📱 Developers testing their applications on real devices;
- 🎮 Gamers installing modified versions of games (e.g., with Lucky Patcher);
- 🔧 Advanced users using alternative stores like APKMirror or F-Droid.

Method 1: Resolution through security settings (main method)
This is the most reliable and versatile way for MIUI 11. Unlike older versions of Android, there is no global switch here - rights are issued separately for each application that the APK will install.

|---|---|---|---|
| Through security settings | ⭐ (simple) | ❌ No. | ✅ Yes. |
| Through ADB | ⭐⭐⭐ (middle-of-the-road) | ✅ Yes. | ⚠️ Partially. |
