How to Open and Set APK-File on the Xiaomi smartphone: detailed instructions

Why Xiaomi is blocking APK installation and how to fix it

You downloaded an app in APK format, but Xiaomi's smartphone refuses to open it? It's no coincidence that the manufacturer deliberately restricts the installation of programs from third-party sources. The reasons are rooted in the MIUI security policy: the system protects users from malware, but often blocks legitimate files, for example, if you are trying to install a modified version of YouTube or a beta version of a game that has not yet been released on Google Play.

Complicating the problem is that Xiaomi regularly updates its security mechanisms. What worked on the Redmi Note 10 in 2022 may not work on the POCO F5 with the latest version of MIUI 14.
