Why Redmi? 9C NFC does not allow the transfer of applications to SD-standard-map?

Owners of Xiaomi Redmi 9C NFC Frequently encountered problem: despite the availability of a microSD slot (up to the 512 GB), Android system 10/11 Blocks the "Move to the button" SD-Maps are in the app settings, and it's because of Google's policy and the firmware. MIUI.

Since Android 6.0, Google has limited the default portability of apps to external drives. Manufacturers including Xiaomi can implement this feature in their own way or not at all. In the case of the Redmi 9C NFC (model M2006C3MG), standard portability is blocked, but there are workarounds. Next, we will examine all working methods, including those that do not require root rights.

It's important to understand that not all apps can be ported, for example, system services (com.miui.gallery, com.android.settings) and instant messengers like WhatsApp or Telegram usually remain in internal memory, but games (Genshin Impact, PUBG Mobile) and heavy programs (Google Maps, Netflix) are often portable.
