SD-Map is one of the most effective ways to free up space, but in Android (especially on the Internet). MIUI) Unlike the older versions of the system, where the memory card could be formatted as an internal storage, Redmi has a nuanced process. 7A s MIUI 10/11/12 algorithm.

In this article, we will discuss three working methods for installing applications on the SD-map: through the settings of the smartphone, using ADB You'll also learn which applications can't be transferred to the memory card (which will cause malfunctions), how to properly prepare them. SD-This is the map and what to do if the system says "Not enough space" error. 7A taking into account the features of its firmware and hardware limitations.

1. Preparation SD-maps: requirements and formatting

Before transferring applications, make sure your SD-The card meets the minimum requirements:

• 🔹 Speed class: not lower than Class 10 (recommended) UHS-I or UHS-II steady-work).

Method 2: Using ADB for Forced Transfer

If you don’t have a port option, you can use Android Debug Bridge (ADB) — a debugging tool that allows you to forcibly move applications to SD-This method requires connecting the smartphone to a computer.

(This team is setting up SD-Map as default storage for new applications.)

adb shell pm move-package com.example.app /sdcard

(Replace com.example.app with a batch name for the app, such as com.whatsapp.)
