How to transfer Xiaomi apps to a memory card: the complete guide

Xiaomi smartphone owners often face a lack of built-in storage, especially on the budget models of the Redmi and POCO series, where memory is limited and system files occupy a significant part.Moving applications to an external drive seems a logical solution to the problem, allowing you to free up precious gigabytes for new games, messengers and photo albums. However, the interface of the shell of MIUI and Android has its own features that hide this feature from the average user.

Modern versions of Android, starting with 6.0 and up, provide the Adoptable Storage mechanism that allows you to turn a microSD card into part of the system partition. It is important to understand that Xiaomi, like Samsung, hides this option by default in the standard settings menu. This is done to ensure the stability of the device, since the read speed of external drives is often lower than that of the built-in flash memory eMMC or UFS.

However, there are proven ways to get around these limitations and make the system work with the system. SD-In this article, we will discuss data transfer methods, the risks associated with loss of information, and step-by-step instructions for configuring virtual memory on your device without obtaining root permissions.

Preparation SD-maps and compatibility checks

Before you start complex manipulations, you need to make sure the quality of the drive used. To work in internal memory mode, you need a card with a high write and read speed, classified as Class 10, U3 or V30. Using a slow card will cause applications to run for a very long time, and the system will start to slow down when performing background tasks.

Make sure to back up all the data on the card. The process of formatting with internal memory will completely destroy all files, photos and documents. Once formatted, the card will become unreadable for other devices, such as PCs or cameras, without first back-formatting.

• 📱 Make sure your smartphone supports cards over 32GB (modern Xiaomi models run at 256GB or higher).
• 💾 Use maps of proven brands: SanDisk, Samsung, Kingston to avoid data loss.
• ⚡ Check the speed of the card with the help of the utility A1 SD Bench before the start of the procedure.
• 🔋 Charge the device to at least 60% to avoid formatting failure.

Put the card into the slot and wait for the system notification. If you have previously used this card as a portable storage, it must be pre-cleaned. Go to Settings → About Phone → Storage, select your card and click Clear.

The method of formatting as internal memory (Adoptable Storage)

This is the main and most reliable way to bring apps to Xiaomi. It's to get Android to count. SD-The map is the system partition. MIUI The button "Use as internal storage" is often missing, we will apply a small trick through the developer settings.

First, you need to activate the developer mode. → About the phone and quickly press 7 times on the item "Version" MIUI". After the message “You became a developer” appears, go back to the main settings menu and select Additional settings. → For developers.

In the list of parameters, find the item "Forced permission to record externally SD-Force allow apps on external. Activate this switch, which will allow the system to offer formatting as internal memory, even if the manufacturer did not consider it fast enough.

After activating the hidden function, go to the storage management menu. The path may differ depending on the version. MIUI: Settings → Memory or Settings → The phone. → Storage, click on your name. SD-The menu that appears should have a new action: "Format as an internal storage device".

The system will warn you that all data will be deleted. Confirm the action and wait for the process to be completed. Once completed, the system will suggest migrating already installed applications and media files. Select the option of "Move now" or "Move later" to do this manually.

⚠️ Warning: Once formatted, the card is encrypted with a specific device key, so you can't just insert it into another phone or computer and read the data.

Manual transfer of already installed applications

Once the card is formatted as internal memory, Android gets the right to move the application data to it, but this doesn't always happen automatically for all programs, you'll need to manually specify which apps you want to move.

Go to Settings → Applications → All apps. Find the program you want to move (such as a heavy game or a navigator) in the list. Click on it to open the details.

In the app menu, find the item "Storage." If the app supports portability, you'll see the "Change" or "Move to" button. SD-Click on it and confirm the action. It can take anywhere from a few seconds to a few minutes depending on the size of the application.

• 🚀 Move primarily games and heavy apps that take up a lot of space.
• ⚙️ System applications and desktop widgets are often impossible to move due to Android limitations.
• 📸 Camera and voice recorder apps may require you to set up file saves separately in their own menus.

It is worth noting that not all application developers allow porting, which is because some programs are critically dependent on the high memory response rate that they can get. SD-In this case, the movement button will be missing or inactive (grey).

Camera and Multimedia Setup by Default

One of the main reasons for memory shortage is the accumulation of photos and videos. After successfully formatting the card as internal memory, the Xiaomi camera must automatically start saving new images to an external drive.

Open the Camera app and click on the menu icon (three bars or gears) in the corner of the screen. SD-map" or "Save Way" and make sure the switch is activated. MIUI This item may be in the "Camera Settings" section".

For instant messengers like WhatsApp, Telegram or Viber, settings are saved inside the apps themselves. For example, on WhatsApp, you need to go to Settings → Chats → Backup or Storage settings to change the way you save media files, if such an option is available in your version.

It is also recommended to check the settings of the recorder and document scanner if you are actively using them. These applications often save files to internal memory by default, ignoring the general setting of the system.

💡

Use the file manager to move old folders. Go to the internal memory, find folders. DCIM, Download, Movies and move their content to SD-manually, if the system has not done so by itself.

Using ADB for Forced Transfer

If standard methods don’t work or there’s no transfer button, you can use ADB (Android Debug Bridge) debugging, which requires connecting your smartphone to your computer and installing drivers, but it gives you deep access to the file system.

To start, enable USB debugging in the Developer menu. Connect your phone to your PC with a cable. On your computer, open the command line in the ADB folder and enter a command to check the connection:

adb devices

You'll see a request for debugging permission on your smartphone screen, confirm it. Then, to force the app to move, you'll need to know its batch name (e.g., com.android.chrome).

adb shell pm move-package com.android.chrome external

This method allows you to port even those applications that the system normally blocks, but be careful: moving system services can lead to unstable operation of the phone. Use this command only for user applications.

⚠️ Note: Do not try to migrate the system components of Google Play Services or the system interface MIUI through ADB. This can lead to a cyclic reboot and will require resetting settings.

Possible problems and solutions

In the process of operating a smartphone with a formatted SD-There are a lot of errors in the map, and most of the time, users are confronted with a message "SD-The card is corrupted" or the sudden disappearance of the application icons.This can be caused by both a software failure and physical damage to the card.

If the apps stopped opening, try restarting the device. Often the system just loses its way to the files after updating or power failure. If the reboot didn't help, extract the map, wipe the contacts and paste back before clicking.

In the case of persistent "Low Speed" errors or interface freezes, the memory card is probably exhausted. Flash memory has a limited number of rewriting cycles. If the card is used intensively for more than 2-3 years, its performance may have fallen below the critical level.

• 🔄 Try formatting the card again through the phone's settings menu (not through PC).
• 🔍 Check the card for errors using the Error Check utility on your computer.
• 📉 If the card is warming up in the area of the slot, it may indicate problems with the phone controller.

Also worth mentioning is the widget problem: Once you transfer the app to the map, its widget on the desktop may stop updating or disappear, in which case, remove the widget and add it again from the widget menu.

💡

Stability of the smartphone with applications on SD-The card is directly dependent on the quality of the drive itself, and savings on the memory card often lead to data loss and nervous breakdowns.
