How to transfer applications to SD-map 8T: way + restriction MIUI

Owners of Xiaomi 8T Often face a lack of internal memory, especially if the model was purchased with 64 or 128 GB of storage. SD-The map seems to be a logical solution, but in MIUI Unlike older versions of Android, where the feature was available out of the box, modern Xiaomi firmware limits the user experience — and it’s not always clear why.

In this article, we will discuss all the working ways to port applications to SD in Xiaomi 8T (currently for MIUI 12, 13 and 14), including bypassing the system constraints, you will learn which applications can be ported and which ones can not, how to format a memory card correctly and what to do if the function is not available, and consider alternative methods for freeing up memory if transfer is impossible.

Why Xiaomi 8T You cannot transfer all applications to SD-map?

The main reason for the restrictions is the security policy of MIUI. Since Android 9.0 (and the corresponding versions of MIUI), Google has tightened the requirements for working with external drives. Xiaomi went further and completely removed the standard portability feature for most applications, leaving it only for:

• 📱 Third-party applications that support adoptable storage).
• 🎮 Supported games SD (Genshin Impact, Call of Duty Mobile).
• 📁 Media files (photos, videos, music) – they can be moved manually.

System applications (Mi Browser, Mi Music, Security) and many popular services (WhatsApp, Telegram, Instagram) are blocked at the MIUI level. Attempt to move them leads to the error "App cannot be moved."

⚠️ Note: If you see a message "SD-The card is slow when you try to transfer, which means that your card has a speed class below. UHS-I (U1) formatted FAT32 versus exFAT. MIUI Automatically block the transfer to such media.

Preparation SD-Maps: Formatting and Selection of Speed Class

Before transferring applications, be sure to check the parameters of your SD-map. MIUI makes strict demands:

1. Speed class: minimum UHS-I (U1) or Class 10. Class 4/6 cards will not work.
2. Format: exFAT (recommended) or FAT32 (with a file limit of >4 GB).
3. Size: From 32GB. Cards less than 16GB MIUI may not recognize as “application-appropriate.”

To format the card directly in the smartphone:

1. Put it in. SD-map 8T.
2. Go to Settings. → Warehouse → SD-map.
3. Click Format → As internal storage (this activates adoptable storage).
4. Confirm the action. Attention: all data on the map will be erased!

💡

If the card is not defined as internal storage after formatting, restart the phone. Sometimes MIUI requires restarting to apply the changes.

After formatting, the system will offer to transfer some of the data to SD. Agree - this will accelerate further manipulation of applications.

Method 1: Transfer through standard MIUI settings

This is the simplest method, but it only works for supported applications.

1. Open Settings → Applications → Application Management.
2. Select the app you want to migrate (like Spotify).
3. Press Warehouse. → Change. → SD-map.
4. Confirm the transfer. The process can take up to 5 minutes.

If the Change button is inactive or absent, it means:

• 🚫 The annex does not support portability (see table above).
• 🔄 Memory card is not formatted as internal storage.
• 📉 There is not enough space on the map (at least 10% of free space is needed).

⚠️ Note: After the transfer, the application may run slower, especially if the application is not SD-class U1 (not U3). Tests show that delays at launch increase by 20-40%.

Method 2: Use of ADB (for power users)

If the standard method didn’t work, you can try forced transfer via ADB (Android Debug Bridge), which requires a PC and basic command line knowledge.

What you need:

• 🖥️ Computer with installed ADB Tools.
• 📱 Included debugging by USB Xiaomi 8T (Settings → The phone. → Version. MIUI — Press 7 times, then return to Additional → For developers → Debugging by USB).
• 🔌 USB-cable (preferably original).

Step-by-step:

1. Connect your phone to your PC and confirm access via USB.
2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with adb.exe.
3. Enter the command to check the connection: Adb devices should appear serial number of your Xiaomi 8T.
4. Find out the batch name of the application (for example, for Telegram it is org.telegram.messenger). You can do this through the App Inspector in Settings → For developers.
5. Execute the transfer command: adb shell pm set-install-location 2 This command sets the priority of installation on the SD-map for all supported applications.
6. Reinstall the application you want. It will automatically install on the SD.

Important: The pm set-install-location 2 command does not guarantee that all applications will be ported, and some (such as Google Play Services) will still remain in internal memory.

Method 3: Transfer through file manager (data only)

If you can not transfer the application itself, you can free up space by moving its cache and media files to the SD-This will work for you:

• 🎵 Music Players (Spotify, Yandex Music).
• 🎬 Video players (VLC, Kodi).
• 📸 Photos (Google Photos, Gallery).

Instructions:

1. Open a file manager (such as Mi File Manager).
2. Go to the Android → data folder → [name packet application].
3. Find the cache, media, or files folders.
4. Select files and click Cut (do not copy!).
5. Go to the SD-map, create a folder with the name of the application and paste files.

Some applications (like Google Maps) will need to change the default save path:

1. Open the application settings.
2. Find the Warehouse or Downloads section.
3. Show the way. SD-map, /storage/1234-5678/Download).

Limitations and risks of porting applications to SD

Transfer of applications to SD-map 8T It's not just pros, it's also bad:

Another nuance: applications with a widget (like Pocket or Evernote) may lose widget functionality after porting to SD, due to Android’s restrictions on accessing external drives for background processes.

⚠️ Attention: If you are using SD-The card is an internal storage device, it cannot be read on another device without formatting. MIUI encrypt data for protection.

Alternative ways to free up memory in Xiaomi 8T

If SD transfer is not possible, consider these methods:

• 🧹 Cache Clearing: Go to Settings → Warehouse → Cleaning and removing unnecessary files. MIUI Often accumulates up to 1-2 GB of garbage.
• ☁️ Cloud Storage: Move photos and videos to Google Photos or Mi Cloud (gives 5GB for free).
• 🔄 PC portability: Regularly copy heavy files (movies, archives) to your computer.
• 🗑️ Removing duplicates: Use Files by Google or CCleaner to find duplicate files.
• 📦 Lite versions of applications: Install lightweight versions (Facebook Lite, Messenger Lite).

There is a separate life hack for games: many titles (such as Asphalt 9 or Free Fire) allow you to upload additional files to SD.

1. Set the game into your internal memory.
2. Run it and wait for the request to download the data.
3. Choose. SD-map.

💡

If the internal memory is 90 times full%+, MIUI Try to keep at least 10-15% of the free space for stable operation of the system.
