How to transfer applications to the flash drive in Xiaomi Redmi 8T: 3 working ways

Xiaomi Redmi 8T is a popular smartphone with expandable memory, but even 64 GB of internal storage quickly run out if you actively install games and applications. Shifting some of the software to a microSD card helps to free up space, but in MIUI this feature does not work as clearly as in pure Android. In this article, we will analyze all the ways to transfer applications to the flash drive, including hidden settings, storage requirements and solutions to typical errors.

It's important to understand that not all apps can be ported, for example, system utilities and some messengers (like WhatsApp) block this feature for security reasons. 8T s MIUI 12+ function “Mobilization to SD" It can be hidden in the developer or require formatting the flash drive as an internal storage, which has its pros and cons.

1.Preparation: Which flash drive is right for the Redmi 8T

Not every microSD will work correctly. For the Redmi 8T (model M1908C3JG), the best cards are:

• 🔹 Speed class: not lower UHS-I Class 10 (or) U1). For games and heavy applications, it is better U3 or V30.
• 🔹 Capacity: 32GB to 512GB (maximum that supports Redmi slot) 8T).
• 🔹 Format: FAT32 (by default or exFAT (if card) >64 GB) Internal storage will be required ext4 (automatically formatted by the system).
• 🔹 Brands: SanDisk Ultra, Samsung EVO, Kingston Canvas - proven options without "hanging".

⚠️ Attention: Cheap cards without a brand often have an understated real write speed, which leads to lags when you run ported applications. A1 SD Bench (available on Play Market).

Method 2: Transfer through standard MIUI settings

The easiest method is to use the built-in MIUI function, which works for most user applications (games, social networks, multimedia), but not for system applications.

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the app you want (like Facebook or Spotify).
3. Slip on Warehouse.
4. If the option is active, click Move to SD-Map (or Modify in new versions) MIUI).
5. Wait until the process is complete (it can take up to 5 minutes for major games).

⚠️ Attention: B MIUI 14 item “Move to SD" It can be missing if the flash drive is formatted as a portable storage device:

Format the card as an internal storage (erase all data) |

Enable the developer mode and activate "Debugging by USB" |

Update MIUI to the latest version (in old firmware bugs with hidden options)|

Reboot the phone after connecting the flash drive-->

💡

If the "Transfer" button is inactive, try clearing the app cache in the same Warehouse menu.

Method 2: Formatting a flash drive as an internal storage device

This method allows you to carry more applications, but has risks: once formatted, the card will not be read on other devices (for example, on a PC or camera), but the system will perceive it as part of the main memory.

Step-by-step:

1. Insert the flash drive in the Redmi 8T.
2. Go to Settings. → Warehouse.
3. Tap your name on it. SD-maps (e.g. SanDisk) 128GB).
4. In the upper right corner, click on three dots → Storage settings.
5. Choose to format as internal.
6. Confirm the action (all data on the map will be erased!).
7. After formatting, the system will prompt you to Transfer the data – agree.

Now, when you install new applications, the system will ask where to save them, so you can move those that are already installed.

• 📱 Go to Settings. → Annexes.
• 🔍 Select the desired application → Warehouse → Change.
• 💾 Indicate. SD-map and confirm.

Method 3: Transfer over ADB (for power users)

What you need:

• 🖥️ Computer with Windows/Linux/MacOS.
• 🔌 Cable USB Type-C (original, undamaged).

You can find the package through the App Inspector app (available in the Play Market).

Reboot the phone.

⚠️ Note: Some apps (e.g. Google Play Services) after porting through ADB If you have errors after the reboot, return the application back with the command:

adb shell pm move-package --internal com.example.app

💡

ADB is the only way to port system applications (like Galery or Music), but it takes care not to tolerate critical services like Google Play or MIUI System!

5. which applications cannot be transferred to the flash drive

Even with ADB, some programs remain “tied” to internal memory, and here is the full list of limitations for the Redmi 8T:

💡

If you are critically short of space, try migrating the app’s cache and data instead of the app itself. To do this, select Clear Cache from the App Store menu, and then manually move the data folder (e.g. /Android/data/com.game.example) to the flash drive via the file manager.

6. Solving typical errors in the transfer

When you use a flash drive on the Redmi 8T, you're going to have a few common problems, and here's how to fix them:

• 🚫 "Not enough space on the device" error: Reason: The flash drive is formatted as portable, but the application does not support portability. Solution: use ADB Or format the map as an internal one.
• 🔄 App moved but won't start: Reason: Low speed reading flash drive Solution: check map for speed (should be >10 MB/s) or replace by UHS-I U3.
• ⚠️ "SD-Card corrupted": Cause: Incorrect extraction or failure of the file system.Solution: format the card on a PC in the FAT32 and reconnect.
• 📱 After the transfer, the app icon disappeared: Cause: Launcher Conflict. Solution: Reboot your phone or reset your launcher settings (Settings) → Home screen → Drop it).

⚠️ Warning: If after formatting the flash drive as internal storage, the phone started to brake, the card is probably too slow. → Warehouse → SD-map → Formatted as portable (data will be erased!).

7. Alternative ways to free up memory

If the application portability is not helpful or impossible, use these methods:

• 🧹 Cache Clearing: Go to Settings → Warehouse → Clean up and delete unnecessary files, especially Facebook, Instagram and browsers accumulate a lot of garbage.
• ☁️ Cloud Storage: Move photos and videos to Google Photos or Mi Cloud (into Google Photos) MIUI It has built-in synchronization).
• 🎮 Lite versions of apps: Install lightweight versions of social networks: Facebook Lite, Messenger Lite, Twitter Lite. They take up 5-10 times less space.
