Why Redmi Note is missing memory and how to fix it
Xiaomi Redmi Note (especially budget models of the Note series) 8/9/10/11) Even after cleaning the cache and deleting the files, the system insists on saying, "Memory is full." MIUI, where many applications are installed in internal memory by default, and transfer to SD-The card is blocked for security reasonsยป.
The manufacturer argues that external drives are slower than the built-in eMMC/UFS memory, which can lead to lags. However, for users with only 32-64 GB of internal memory and applications that take up 20+ GB, this argument is not encouraging. Fortunately, there are legal and non-obvious ways to get around the restrictions, from standard MIUI functions to manual transfer via ADB.
In this article, we will discuss all working methods for the Redmi Note 8 Pro, Note 9, Note 10, Note 11 and others, including bypassing locks on the latest versions of MIUI 14. Importantly, not all applications can be transferred - some (for example, system or widget) will remain in internal memory.
Preparation: what kind SD-Choose a map for the Redmi Note
Before you port applications, make sure your microSD card meets the requirements:
- ๐น Speed class: minimum class 10 (UHS-I/UHS-II Class cards are preferred. 4/6 They will slow down applications.
- ๐น Volume: from 32 GB (optimally 64-128 GB). 16 GB cards will fill up quickly.
- ๐น Formatting: in only FAT32 exFAT (NTFS unsupported!).
- ๐น Brand: Avoid no-name cards - they are often forged. - SanDisk, Samsung EVO, Kingston.
โ ๏ธ Note: If you use the card as internal storage (Adoptable Storage feature in Android), remember:
- The card will be encrypted and will not be read on other devices.
- When you remove the map, the applications on it will stop working.
- Application speeds will drop by 20-40% compared to internal memory.
| Redmi Note model | Max. SD volume. | Adoptable Storage Support | Recommended grade |
|---|---|---|---|
| Redmi Note 8/8 Pro | 256GB | Yes (Android 9-11) | UHS-I (U3) |
| Redmi Note 9/9 Pro | 512GB | Yes (Android 10-12) | UHS-I (U3) |
| Redmi Note 10/10 Pro | 1 TB | Yes (Android 11-13) | UHS-II (U3) |
| Redmi Note 11/11 Pro | 1 TB | No (MIUI 13+) | UHS-II (U3) |
In the Redmi Note 11 and later, Adoptable Storage is disabled at the MIUI level โ application transfer is possible only through ADB or manual file transfer.
Method 1: Standard porting through MIUI settings (for older versions)
This method works on the Redmi Note 8/9/10 with MIUI 12 and below, and in newer versions, the option can be hidden or blocked.
- Put it in. SD-slot card (hybrid or dedicated).
- Open Settings โ Applications โ Application Management.
- Select the app you want to migrate (like Facebook or Spotify).
- Press Warehouse. โ Change. โ SD-map.
- Confirm the transfer and wait until the completion (may take up to 5 minutes).
โ ๏ธ Note: Not all applications support portability. If the button Change is inactive:
- The application is system-based (e.g. Google Play Services).
- The app has a widget on the main screen.
- The developer has blocked the transfer in the manifesto (android:installLocation="internalOnly").

Method 2: Use of the SD-The card is an internal memory (adoptable storage)
This method allows you to โdeceiveโ the system, making it perceive SD-The card is part of the internal storage. It only works on Android. 9โ11 (MIUI 12 On and below. MIUI 13/14 function.
- Put it in. SD-phone-card.
- When the notice โNewโ appears SD-map" press Set up.
- Choose Use as internal storage (not Portable storage!).
- Confirm the formatting (all data on the map will be deleted!).
- After formatting, select Move Data Now or do it manually later.
๐น Pros of the method:
- Applications are installed on the map automatically when there is a shortage of space.
- You can even migrate applications that donโt normally support portability.
โ ๏ธ Attention:
- The card will be tied to the phone โ it will not be read on a PC or other smartphone.
- The speed of the application will drop, especially if the card is cheap.
- When you remove the card, the applications will stop working until it returns.
What if the โUse as internal storageโ option does not appear?
Method 3: Transfer over ADB (for power users)
If standard methods donโt work (e.g., on the Redmi Note 11 with MIUI 14), you can use Android Debug Bridge (ADB), which requires a PC and basic command line knowledge.
Step 1. Enable debugging over USB:
- Go to Settings โ About Phone โ MIUI version and press 7 times to activate Developer Mode.
- Back to Settings โ Additionally. โ For developers.
- Activate Debugging via USB and confirm the resolution.
Step 2. Connect your phone to your PC and execute the commands:
- Download ADB Tools and unpack.
- Open the command prompt (Win + R โ cmd) and go to the folder with ADB:
cd C:\platform-tools- Connect the phone and type in:
adb devices(A device should appear. If not, check the drivers.)
- Enter the port command (replace com.example.app with the application package):
adb shell pm set-install-location 2
adb shell pm move-package com.example.app๐น How to find out the application package:
- Use the App Inspector app from Google Play.
- Or enter in ADB:
adb shell pm list packages -fโ ๏ธ Attention:
- Not all apps support ADB portability (depending on the Android:installLocation flag in the manifest).
- After the MIUI update, you may need to repeat the procedure.
- Donโt tolerate system applications โ this can lead to the collapse of MIUI.
๐ก
If the pm move-package command returns the error "Failure" [INSTALL_FAILED_INVALID_INSTALL_LOCATION]", This means that the application is locked for portability. Try an alternative method with manual file movement (described below).
Method 4: Manual transfer of application files (without root)
If none of the above methods worked, you can try to manually copy the application files to the SD-This method does not carry the application completely, but allows you to free up space by moving heavy data (cache, media files).
Instructions:
- Install a file manager with access to system folders (e.g. FX File Explorer or Solid Explorer).
- Go to /data/app/ (root rights or access via ADB required).
- Find a folder with an app package (e.g. com.facebook.katana for Facebook).
- Copy the folder to SD-map (e.g. in the /storage/XXXX-XXXX/Android/obb/).
- Create a symbolic link in the original folder (root or ADB required):
adb shell
su
ln -s /storage/XXXX-XXXX/Android/obb/com.facebook.katana /data/app/com.facebook.katana๐น Limitations of method:
- Without root rights, links wonโt work โ the app will only โseeโ the original location.
- After the application update, the files can be returned to internal memory.
- Some applications (such as games) check the integrity of files and can crash.
๐ก
Manual file transfer is the only way to free up space on the Redmi Note 11/12 without root, but it requires a repeat after each update to the app.
Method 5: Transfer applications using root rights
If you have root access (for example, through Magisk), you can use apps like Link2SD or App2SD that allow you to:
- ๐น Move over APK-file-and-data applications SD-map.
- ๐น Create symbolic links to cheat the system.
- ๐น Freeze unnecessary system applications, freeing up space.
๐น Step-by-step instructions for Link2SD:
- Install Link2SD from Google Play.
- Give root access.
- Select the application โ Link up โ specify SD-map as target storage.
- Reboot the phone.
โ ๏ธ Attention:
- Not all applications will work after the transfer (especially system ones).
- Symbolic links may break after the MIUI update.
- Using root eliminates warranties and increases the risk of hacking.
Frequent mistakes and their solutions
When transferring applications to SD-And these are the most common problems that people have with this map, and the ways that they can solve them:
| Mistake. | Reason. | Decision |
|---|---|---|
| The โMove to SDโ button is inactive | Application does not support transfer | Use ADB or manual file transfer |
| App dyes after transfer | Low speed. SD-map | Buy a UHS-I/UHS-II class card |
| There's not enough room for SD-map | The card is formatted in FAT32 (limit 4 GB per file) | Reformatting to exFAT |
| ADB does not see the device | Drivers not installed | Install Mi PC Suite or ADB drivers |
๐น Additional advice:
- If the app slows down after the transfer, try clearing the cache (Settings โ Apps โ Storage โ Clear the cache).
- For games like Genshin Impact or Call of Duty Mobile, itโs better to leave the data in your internal memory โ they require high read speeds.
- Check regularly SD-Error map through Settings โ Warehouse โ SD-map โ Check for errors.
