Transfer applications to memory card in Xiaomi Redmi Note 8T: all ways

Owners of Xiaomi Redmi Note 8T often face a shortage of internal memory, especially if the device has been in use for several years. Even after cleaning the cache and removing unnecessary files, system updates, high-resolution photos and modern applications quickly fill the limited 32/64/128 GB. The microSD card seems to be the obvious solution - but how to transfer applications to it if MIUI does not have the standard option "Move to SD"?

Complicating the problem, since Android 6.0, Google has restricted the ability to port applications to external drives for security reasons. Manufacturers including Xiaomi have gone even further: in the latest versions of MIUI 12/13/14, the portability is either hidden or selective. However, workarounds exist, from built-in tools to manually mounting a partition through ADB. In this article, we will examine all the current methods, their pros and pitfalls.

Why is the Redmi Note 8T not using the “Move to SD” button?

The reason for this is a combination of two factors: Google’s policies and firmware features. MIUI. Since 2015, Android has allowed you to transfer to the memory card only that part of the application that does not contain critical data for work (so-called “memory card”). APK + OBB-Executable files and cache remain in internal memory. Xiaomi went even further:

• 🔹 V MIUI 11 and older function of transferring applications to SD Deactivated by default – it must be activated through hidden settings.
• 🔹 Some applications (for example, WhatsApp, Telegram, system services) do not support transfer because of the work with notifications and background processes.
• 🔹 The memory card must be formatted as an internal storage (Adoptable Storage), which leads to its "binding" to the device and the inability to use on other gadgets.

In addition, the Redmi Note 8T is equipped with a Qualcomm Snapdragon 665 processor that does not support App2SD technology at the hardware level, which means that even after transferring, application performance can fall – memory cards (especially A1 class) are slower than the internal memory of eMMC 5.1.

⚠️ Warning: Formatting the memory card as an internal storage card will result in total loss of data on it. Backup is mandatory! Once formatted, the card cannot be retrieved without resetting the phone to the factory settings.

Method 1: Enabling a hidden transfer function in MIUI

The easiest method is to activate the hidden port option through the developer settings. It runs on the Redmi Note 8T with MIUI 11-14 firmware (inclusive), but requires preliminary preparation:

1. Activate Developer Mode: Go to Settings → About Phone → MIUI Version and tap it 7 times.
2. Return to the main settings menu, open Additional settings → Developer settings.
3. Find Forced Allow Transfer to SD (or Force Allow Apps on External) and turn it on.
4. Reboot the phone.

After the reboot:

1. Open Settings → Applications → Application Management.
2. Select the app you want (like Spotify or Google Maps).
3. Slip on the vault. → Move it to SD-Map (will appear only for compatible applications).

If the button is not active or missing, the application does not support the transfer, in which case only manual mounting will help (see Method 3).

Method 2: Formatting a memory card as an internal storage device

This method allows the memory card to be used as part of the system partition, but has serious limitations: once formatted, the card will become "tied" to the Redmi Note 8T and will not be recognized by other devices (even after extraction), but all compatible applications will be installed on it by default.

Step-by-step:

1. Insert the memory card into the slot (up to 512 GB of A1/A2 or UHS-I class cards are supported).
2. Go to Settings → Storage → Memory Map.
3. Slip on the three dots in the top right corner and select Storage Settings.
4. Click Format as Internal → Clean and Format.
5. Wait until the process is completed (it can take up to 10 minutes).
6. After formatting, select Transfer Data to move supported applications.

⚠️ Note: If you sell or transfer Redmi Note 8T For another user, be sure to remove the memory card before resetting, otherwise the new owners will have access to your data, and the phone may stop loading (due to "loss" of system files).

Method 3: Transfer over ADB (for power users)

If the first two methods fail, you can still mount manually via Android Debug Bridge (ADB). This method requires a computer and basic command line knowledge, but allows you to migrate even those applications that do not normally support. SD-Important: This method only works on unencrypted devices (if you use a pattern lock or a pattern lock). PIN, First, disable encryption in security settings).

What you need:

• 🖥️ Computer with Windows/macOS/Linux and installed Xiaomi drivers.
• 🔌 USB-cable (preferably original).
• 📦 Utility. ADB Tools by Google.
• 📱 Included debugging by USB on the phone (Settings) → Additionally. → For developers).

Instructions:

1. Connect the Redmi Note 8T to your computer and allow debugging over USB.
2. Open the command prompt (cmd in Windows or Terminal in macOS/Linux) and go to the folder with ADB.
3. Enter the command to check the connection: Adb devices should display the serial number of your device.
4. Find out the package name of the application you want (e.g. Facebook is com.facebook.katana) and you can do this by using the command: adb shell pm list packages | grep "application name"
5. Move the app to SD-map: adb shell pm set-install-location 2 adb shell pm move-package com.facebook.katana

If the command is successful, you will see a message Success. To return the application back to internal memory, use:

adb shell pm move-package com.facebook.katana 0

💡

Before transferring through ADB, check the free space on the memory card with the command adb shell df. If the /mnt/expand/... partition is missing, the card is not formatted as internal storage and the transfer will not work.

Which apps can be moved and which ones can’t?

Not all programs support external memory, and here are the key limitations of the Redmi Note 8T:

• ✅ Can we move it:
• ❌ Can't move it:

The reason for the ban on transferring instant messengers and banking applications is security, which works with personal data and notifications, and external drives are easier to compromise (for example, through malware on the computer to which the card is connected).

What to do if the transfer does not work?

If none of the methods worked, check the following points:

1. Memory Card Type: Redmi Note 8T supports microSD up to 512GB, but you need an A1 or higher card to carry applications (e.g. SanDisk Extreme A2). Class C10 cards without A1/A2 marking will not work.
2. File system: The card must be formatted in exFAT or FAT32 (for internal storage, in ext4). You can check the format through the application SD Card Formatter.
3. MIUI Updates: Some firmware versions have portability disabled at the kernel level. Check for updates in Settings → About Phone → System Update.
4. Ruth-Right: If you’re ready for radical measures, getting root through Magisk will open up access to apps like App2SD or Link2SD that allow you to port even system programs.

If the problem persists, try an alternative approach:

• 📁 Transfer only the media files of the applications (for example, downloaded tracks in Spotify or maps in Google Maps) to the memory card.
• ☁️ Use cloud services to free up space (e.g. Google Photos to automatically upload photos).
• 🗑️ Clean the cache regularly through Settings → Warehouse → Cleanup.

Alternative solutions for memory release

If the applications are transferred SD-The card is impossible or impractical, consider other ways to optimize memory on the Redmi Note. 8T:

One of the most effective ways is to archive applications. MIUI has a built-in function: go to Settings → Applications, select an unnecessary application and tap Archive. The application will be frozen, but its data will be saved. To return it, just click Restore.

💡

Transfer of applications to SD-map 8T — It's a temporary solution. For long-term memory optimization, it's better to combine several methods: cache cleaning, application archiving, and cloud storage.
