How to transfer applications to the memory card Android Xiaomi: expert guide

Owners of Xiaomi, Redmi and POCO smartphones often face a critical shortage of built-in storage, especially in budget models with 64 or 128 GB of memory. Android OS overgrows with cache, and modern applications and games take up more space, causing the device to slow down.

But the process of transferring programs to a flash card is not as obvious as it might seem. Standard MIUI settings often hide this option or limit its functionality for the sake of security and stability of the system, you will need not only to insert a card, but also to properly configure the file system, and in some cases, activate hidden developer functions.

In this article, we will discuss in detail all possible ways of data transfer: from standard tools to use. ADB-We will look at the nuances of working with different versions of Android and shells. MIUI, So you can safely free up internal memory without the risk of losing important data or disrupting your gadget.

Preparation of memory card and smartphone for work

The first step is to properly prepare the external drive. Not any memory card is suitable for installing applications, since the speed of reading and writing directly affects the speed of programs. For comfortable work, it is recommended to use UHS-I cards of the class 10 or higher, since slow drives will cause “freezes” and long downloads.

Insert the card into the appropriate slot of your Xiaomi or Redmi device.If the tray is combined, make sure you don't use the second one. SIM-After the physical installation, the system must identify a new storage. Go to Settings. → Memory to see connection status.

The system may suggest formatting the map. This is a mandatory procedure, since the file system must be compatible with Android requirements for working with applications. During the formatting process, all data on the media will be deleted, so save important files on the computer or in the cloud in advance.

⚠️ Note: Formatting a memory card erases all files. Make sure you back up photos and documents before starting the procedure.

It's important to understand the difference between the modes of the drive: the standard Portable Storage mode allows you to store photos and videos, but does not give you complete freedom to install programs, and we will need an Internal Storage mode that turns the USB drive into an extension of system memory.

💡

Use memory cards with a capacity of no more than 256 GB for stable operation of older models of smartphones, as large volumes can be incorrectly indexed by the system.

The standard method of transfer through the MIUI settings

The MIUI shell interface provides basic memory management tools, but their availability depends on the firmware version and device model. In some cases, the system itself will suggest moving data when internal memory is overflowing, but it is better to act preventively.

To start, go to the application management menu. Find the program you want to move in the list. Note that Xiaomi and Google system apps are often blocked for portability, as their work is critical to OS stability.

Select the desired application from the list and click on "Memory." If the function is available, you will see the "Change" or "Move to" button. SD-Clicking on it will start the process of copying files.

• 📱 Open the Settings. → Annexes → All applications.
• 📂 Choose a heavy program that takes up a lot of space.
• 💾 Click on “Memory” and select the move option.
• ⏳ Wait for the process to be completed without turning off the smartphone screen.

It’s worth noting that even after the transfer, some of the data will remain in internal memory, which is normal for Android, as some configuration files and cache must be read at the maximum speed that the built-in drive provides.

Use of the “Internal Storage” mode

The most effective way to address this space shortage is through Adoptable Storage, which allows you to format the map so that the system perceives it as an integral part of the internal drive, and in this mode, new applications will automatically be installed on the USB drive.

To activate this mode, find your memory card in the storage settings. In the control menu, select the option “Format as internal storage.” The system will warn you that the card will be encrypted and can not be read on other devices without re-formatting.

Once formatted, MIUI will suggest migrating existing media files and applications, which can take a long time depending on the amount of data, and it is recommended to connect the device to the charger.

Using this method turns your MicroSD into a system partition, and you can't get it hot, because the phone won't see the apps that are installed on it, and it's a solution for those who plan to use the card all the time.

⚠️ Note: When using internal storage mode, the memory card is tied to a particular smartphone, inserting it into another phone without losing data will not work.

Activation of hidden functions through the engineering menu

In some versions of MIUI, the manufacturer hides the ability to format the card as an internal storage, but this feature can be activated forcibly through the developer menu, which requires caution, but gives full control over memory.

First, unlock access to advanced settings. Go to Settings → About Phone and quickly click on MIUI Version seven times. Once you have become a developer, you can move on to the next step.

In the menu "For developers" find the item "Forced to allow the transfer of applications to the SD-Force allow apps on external: Activating this switch will allow the system to ignore the limitations set by the developers of specific programs.

Once this option is enabled, it is recommended to restart the device, and now when you try to install the application or move it in the settings, you should have more room for maneuver, but remember that not all applications work correctly when this is forced.

Application ADB-Teams for Advanced Users

If the GUI doesn’t provide the right options, the Android Debug Bridge (ADB) comes to the rescue.This method requires connecting your smartphone to your computer and having basic command line skills, but it is the most powerful tool in the user’s arsenal.

To start, enable USB debugging in the Developer Menu and connect the phone to your PC. Make sure the computer has Xiaomi drivers and the ADB platform installed. In the command line, enter a command to check the connection:

adb devices

Once you confirm the connection, you need to know your memory card ID.

adb shell sm list-disks

The system will give you a disk ID, which is usually a disk:179.64, followed by a formatting command that will turn the card into an internal storage, and be very careful when you enter the disk ID.

adb shell sm partition disk:XXX,X private

Where XXX,X is your drive ID, and once you've run a command, the phone can reboot, and this method allows you to bypass the software constraints of MIUI where the standard means are powerless.

Features of the application from an external drive

The transfer of applications to a memory card has its own technical features that every user should know about, the speed of programs depends on the speed class of the card, and even if the application starts, it can run slower than from internal memory, especially for heavy games and navigation.

And then there's some data that's still in the internal storage, and that's because of the Android security architecture, which isolates the processes, so you don't expect to release 100% of the volume that the app takes up.

It is important to take into account that when you reset your phone settings to factory, the data on the formatted internal card will be lost or become unreadable without a special procedure for restoring encryption keys, which is almost impossible at home.

• 🚀 Games can take longer to load due to slower reading speeds.
• 🔒 Widgets and live wallpaper can work unstablely.
• 🔄 Application updates may require temporary free space inside.

It is recommended to transfer to the map only those applications that do not require high performance of the disk subsystem: social networks, instant messengers, simple utilities.

⚠️ Note: Do not remove the memory card while the phone is on if the applications are installed on it. This can lead to system crash or damage to the database of programs.
