How to transfer applications from internal memory to SD-map 8T: 3 proven methods

Xiaomi Redmi 8T owners often face a lack of internal memory, especially if the device has been in use for several years. Even after cleaning the cache and removing unnecessary files, the system can give a notification "Memory is full", blocking the installation of new applications. The solution seems obvious to transfer some of the software to a microSD card, but in MIUI this process has its own nuances.

Unlike the newer Xiaomi models, where the application portability feature is often blocked by the manufacturer, the Redmi 8T (released in 2019) still supports this mechanism — though not for all types of applications. In this article, we will discuss three working methods: standard portability through settings, using ADB for forced movement and alternative methods of memory optimization. It is important to understand that not all programs can be transferred — some (for example, system or widget) will remain in internal memory.

Before you start, make sure that your SD-The card meets the requirements: it must be formatted as an internal storage (not as a portable one) and have a speed class at least lower than the previous one. UHS-I (U1). Otherwise, the apps will slow down or even fail, and if the card is already being used as a portable card, it will have to be reformatted, and that will result in the loss of all the data on it.

Preparation: verification SD-maps and phone settings

Before transferring applications, you need to properly configure a microSD card. Redmi 8T supports cards up to 512 GB, but for stable operation it is better to use models from proven brands: SanDisk Ultra, Samsung EVO or Kingston Canvas. Cheap unnamed cards can cause failures.

To check the current status of the card:

1. Open the Settings → Memory.
2. Click on the line with your name SD-map.
3. See the "Use" section: if "Portable storage" is specified, the card needs to be reformatted.

For formatting as an internal storage:

• 🔄 Go to Settings. → Memory. → SD-map → Set up.
• 📱 Select "Inner Memory" (Warning: All data will be deleted!).
• ⚡ Confirm the action and wait until it is completed (may take 5-10 minutes).
• 🔄 After formatting, the phone will offer to transfer some of the data – agree.

⚠️ Note: Once formatted as an internal storage card, it cannot be retrieved and used in other devices without completely erasing the data. SD-map.

Method 1: Standard Transfer through MIUI Settings

The easiest method is to use the built-in MIUI function, which is suitable for most user applications (games, instant messengers, utilities), but does not work for system programs.

1. Open Settings → Applications → Application Management.
2. Select the app you want to migrate (like Facebook or Spotify).
3. Press "Storage."
4. If you have an option, you'll see a "Change" button next to "Inner Memory." Press it.
5. Choose "SD-map" and confirm the transfer.

The process can take anywhere from a few seconds to a minute depending on the size of the application.

• 📱 The app will remain on the menu, but its data will be stored on the map.
• 🔄 The icon may temporarily disappear – just reboot your phone.
• ⚡ Some features (such as notifications) may be slower.

Application supports portability (no gray text "Modify")

SD-The card is formatted as internal memory.

There is enough free space on the map (at least 10% of the volume)

The phone is connected to charging (for long operations)

Not all apps can be moved this way, such as the Google Play Store, Mi Account or Camera will remain in internal memory. If the Change button is inactive, try alternative methods in the following sections.

Method 2: Transfer over ADB (for power users)

If the standard method didn't work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to force-transfer almost any application, which requires connecting your phone to your computer and basic command line knowledge.

Step 1: Preparation

• 🖥️ Download. ADB Tools for Windows/Mac/Linux.
• 📱 Turn on the phone Developer Mode: go to Settings → About the phone and 7 times click on "Version" MIUI".
• 🔧 Back to Settings → Additionally. → For developers and include "Debugging by" USB".
• 🔌 Connect your phone to your PC through USB-cable (select "File Transfer" mode").

Step 2: Execution of commands

1. Open the command prompt (Windows) or terminal (Mac/Linux) in the folder with ADB.
2. Enter the command to check the connection: Adb devices must appear serial number of your Redmi 8T.
3. Find out the package name of the application (for example, for Facebook it is com.facebook.katana): adb shell pm list packages | grep 'facebook'
4. Move the app to SD-card: adb shell pm move-package com.facebook.katana If the operation was successful, you will see "Success".

⚠️ Attention: Forced transfer through ADB It can cause malfunctions in the application, especially if it uses services in the background (for example, messengers.

If the team returns a Failure error [INSTALL_FAILED_INVALID_INSTALL_LOCATION], This means that the application cannot be transferred even through ADB. In this case, you only need to delete it or use cloud storage.

Method 3: Use of Third-Party Applications (Alternative)

If previous methods didn’t work, you can try specialized tools from Google Play, such as AppMgr III or Link2SD. They offer advanced memory management features, but require root rights to work properly.

Example of AppMgr III:

• 📱 Install the app from Google Play.
• 🔍 Open the "Moveables" tab - here you will see applications that can be moved.
• 📤 Select the right one and click "Move to" SD-map".
• 🔄 Confirm the action and wait for the completion.

The advantages of third-party utilities:

• 📊 Detailed information about the occupied space.
• 🔄 Allows you to transfer cache and application data (if there is root).
• 📱 Supports packet transfer of several applications.

However, there are also disadvantages:

• ⚠️ Without root rights, the functionality is severely reduced.
• 🛑 Some applications may not work well after the transfer.
• 🔒 Risk of installing malware (download only from official sources).

💡

Before using third-party utilities, check reviews and rankings in Google Play. Apps with a score below 4.0 stars and a small number of downloads are best not to install.

5 Which applications cannot be transferred to SD-map

Even with ADB or root rights, some programs are not portable to external storage, due to Android restrictions and Xiaomi policies.

If you need to make room but cannot move key applications, consider alternative solutions:

• 📁 Clear cache and unnecessary files through Settings → Memory. → Cleanup.
• ☁️ Move photos and videos to the cloud (Google Photos, Mi Cloud).
• 🗑️ Remove unused programs (in the MIUI It has a built-in analyzer of rarely used applications).

6. Frequent errors and their solutions

When migrating applications, Redmi 8T users often face typical problems, and here are the most common ones and how to fix them:

Error: “Not enough space on the device” when transferring

Reason: SD-The card is not enough free space or it is formatted as a portable.

Decision:

• 📊 Check the free space on the map (you need at least 10% of its volume).
• 🔄 Reformat the card as an internal memory (see Section 1).

Error: The application has moved, but does not start

Reason: Low reading/writing speed SD-card-in-conflict MIUI.

Decision:

• ⚡ Replace the card with a faster (class) U3 or A2).
• 🔧 Transfer the app back to internal memory.
• 📱 Reboot the phone.

Error: The "Move to SD" button is inactive

Reason: The application does not support portability or the card is not recognized as internal storage.

Decision:

• 🔍 Check if the application is on the list of non-movables (see Section 5).
• 📋 Try transferring through ADB (see section 3).

💡

If the application is unstable after transfer, return it to internal memory. Some programs (especially games) may require high speed access to data, which is not possible. SD-card not able to provide.

7. Alternative ways to free up memory

If the application portability hasn’t solved the memory problem, consider additional optimization methods:

1.Cache and garbage cleanup

• 🧹 Manual: Settings → Memory. → Cleanup → Selecting unnecessary files.
• 🤖 Automatically: Use Files by Google or CCleaner.

2. Transfer of media files

• 📷 Photo/Video: Move to Google Photos (up to 15GB free) or PC.
• 🎵 Music: use streaming services (Spotify, Yandex Music).

3. Disabling pre-installed applications

Many system programs (Mi Video, Mi Music, Browser) cannot be removed, but you can disable:

1. Go to Settings → Applications → Application Management.
