However, the manufacturer hides this option behind several layers of protection to prevent the accidental installation of malware. MIUI (12 to 14) and Android (10–14), including specific models.
It's important to understand that permission to install from unknown sources is not just about switching one switch. In recent versions of MIUI, the algorithm has changed to require permission for each application that an APK will install (such as a browser or file manager), and we'll go through all the nuances, including hidden settings for Chinese firmware and bypassing restrictions on blocked downloaders.
Why is Xiaomi blocking APK installations from unknown sources?
According to statistics from Xiaomi Security Center, 68% of Android malware is spread through third-party sources. APK-The manufacturer has implemented multi-layered protection:
- 🔒 Default Blocking – All external sources are prohibited out of the box".
- 🛡️ Verification of signature — MIUI scanner APK before installation.
- 📱 Application binding – permission is not given globally, but for a specific installer (e.g. Chrome or Google Files).
- 🌍 Regional restrictions on Chinese firmware (China) ROM) process.
Xiaomi is also working with Google Play Protect, which automatically blocks apps from suspicious sources, and even after you unlock them, you can see a warning that says, "Play Protect is blocked," and we'll show you how to get around it legally.

Method 2: For Chinese firmware (China ROM) and blocked bootloaders
