How to transfer applications to memory card in Xiaomi Redmi Note 4: all working ways

Xiaomi Redmi Note 4 is still popular due to its balanced performance and reliability, but its main drawback is limited internal memory. Even models with 32 GB or 64 GB quickly fill up if you actively install games and applications. The solution seems obvious: transfer some of the software to a microSD card. However, in MIUI (especially based on Android 6/7), this process is nuanced, and some methods work differently than on other devices.

In this article, we will discuss all the current ways to transfer applications to SD-Redmi Note 4 map, including official tools MIUI, circumvention ADB, We will also focus on common errors (for example, why the “Move” button is inactive) and explain which applications will never be able to move due to the security policies of Google and Xiaomi.

Why can’t Redmi Note 4 just transfer any app to a memory card?

Owners of Redmi Note 4 often face the fact that the option to port applications to the Internet SD-The map is either missing or it's selective. There are three key factors that are responsible:

• 📱 Android version and MIUI: On the Redmi Note 4, it was installed out of the box. MIUI 8 based on Android 6.0 Marshmallow (or Android 7.0 Nougat in late firmware).Beginning with Android 6.0, Google introduced the concept of Adoptable Storage (associating the card as internal memory), but Xiaomi disabled this feature in standard builds. MIUI.
• 🔒 Security policy: Many apps (e.g. WhatsApp, Google Play Services, banking clients) block porting to the Internet SD-card due to the risk of data theft or disruption.
• 🛠️ Manufacturer restrictions: Xiaomi artificially limits the portability of system and preinstalled applications to avoid conflicts with firmware.

It is important to understand that even if you see the button “Move to the SD-map" in the application settings, this does not guarantee successful transfer. OBB-files (e.g., files, PUBG Mobile or Genshin Impact often refuse to work after the transfer, because their data remains in internal memory.

⚠️ Attention: Transfer of applications to SD-Class 4 or Class 6 cards can lead to lags and departures. UHS-I (Class 10) or higher, formatted in exFAT or FAT32.

Method 1: Standard transfer through MIUI settings (without root)

It’s the easiest method, but it doesn’t work for all apps.It’s suitable for the Redmi Note 4 on any MIUI version (including MIUI 8/9/10/11).

Instructions:

1. Open the Settings → Applications.
2. Select the app you want from the list (like Facebook or Spotify).
3. Slip on Warehouse.
4. If the option is available, click Move to SD-map (or modify) → SD-map MIUI).
5. Confirm the action and wait until the process is completed (may take up to 5 minutes).

Limitations of the method:

• 🚫 Does not work for system applications (Mi Browser, Security, Gallery, etc.).
• 🚫 Not all third-party apps support portability (such as Instagram or Telegram).
• 🚫 After the transfer, the application may run slower if SD-map.

If the “Transfer” button is inactive, try the following steps:

1. Reboot your smartphone.
2. Clear the app cache in Settings → Apps → [Selected App] → Clear the cache.
3. Try to migrate another application – perhaps the limitation is imposed by the developer of a particular software.

Method 2: Using ADB for forced transfer (without root)

If the standard method didn't work, you can use Android Debug Bridge (ADB), a debugging tool that lets you manually tell the system where to install applications, which doesn't require root rights, but requires a computer and enabled USB debugging.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI until the notification “You’ve become a developer” appears.

USB debugging

• Back to Settings → Additionally. → For developers.
• Activate the debugging switch over USB.
• Connect Redmi Note 4 to your computer via USB-Cable (use the original cable for stability).
• Download and install ADB Tools on your computer.
• Open the command prompt (cmd in Windows or Terminal in macOS/Linux) and type: adb devices Make sure your device appears in the list (permission confirmation may be required on your smartphone).
• Enter the command to port the application (replace com.example.app with your application’s batch name, such as com.facebook.katana for Facebook): adb shell pm set-install-location 2 This command installs the SD-Map as the default installation location for new applications.
• To transfer an already installed application, use: adb shell pm move-package com.example.app

If the team is successful, you will see a message of success, otherwise you may get an error:

• Failure [INSTALL_FAILED_INVALID_INSTALL_LOCATION] — Application does not support transfer.
• Failure [INSTALL_FAILED_MEDIA_UNAVAILABLE] — SD-The card is not recognized or damaged.

⚠️ Note: After using pm set-install-location 2, all new applications will be installed on the site. SD-This can cause performance problems. To return the settings to the original settings, do: adb shell pm set-install-location 0 (where 0 is automatic selection, 1 is internal memory).

Method 3: Transfer applications using root rights (advanced method)

If the first two fail, the radical solution is root rights, which gives you complete control of the system, but it's not guaranteed, and it can lead to unstable operation.

• 🔓 Unlock the bootloader with the Mi Unlock Tool + installation TWRP Magisk.
• 🔓 Use of exploits (e.g. DirtyCOW for older versions) MIUI).

Once root is obtained, you can use applications like Link2SD, App2SD or FolderMount that allow you to:

• 📁 Move over OBB-file-and-data applications SD-map.
• 🔄 Create symbolic links (symlinks) to deceive the system.
• 🗄️ Forced to move system applications (risky!).

Instructions for Link2SD:

1. Install Link2SD from Google Play.
2. At the first start, select ext2/ext3/ext4 (if SD-map created or FAT32/exFAT (if not).
3. In the list of applications, select the one you want to transfer.
4. Tap Create a link and select Move to SD-map.
5. Confirm the action and restart the smartphone.

⚠️ Note: Some applications (such as Google Play Store or Mi Account) may stop updating or work correctly after transferring root rights.

💡

Before you get root, make a full data backup via TWRP or Mi PC Suite. This will help restore the smartphone in the event of a crash.

Typical errors and their solutions

When transferring applications to SD-Redmi Note 4 card users often face the following problems:

• 🔄 The “Transfer” button is inactive: Reason: The application does not support porting or SD-The card is formatted as internal memory (in this case, the port option is not required). Solution: try formatting the card as a portable device in Settings → Memory. → SD-map → Settings → Formatting as a portable.
• 🚨 Error "Insufficient memory" during transfer: Reason: SD-Solution: Check the card for errors via chkdsk (Windows) or fsck (Linux/macOS).
• 🐢 Applications Lay After Transfer: Reason: Low Read/Write Speed SD-Solution: use the cards. UHS-I Class 10 or UHS-II.
• 🔓 App stopped updating: Reason: Root-rights transfer could compromise integrity APK. Solution: Return the app to internal memory before updating.

Alternative solutions: how to free up space without transferring applications

If porting apps doesn’t help or isn’t possible, consider alternative ways to free up memory in Redmi Note 4:

• 🧹 Cache Clearing: Go to Settings → Memory. → Clear the cache. Use Mi Security. → Cleaning to remove unnecessary files.
• ☁️ Transfer media to the cloud: Upload photos and videos to Google Photos or Mi Cloud. Delete local copies after sync.
• 🎮 Remove unused games: Games take up the most space.Remove heavy projects (like Call of Duty Mobile or Asphalt 9) if you don't play them.
• 🔄 Use Lite versions of apps: Replace Facebook with Facebook Lite, Messenger with Messenger Lite, etc.
• 📂 Archiving rarely used files: Compress old documents into ZIP/RAR and move on SD-card.

It’s also worth checking which apps take up the most space:

1. Open the Settings → Applications.
2. Slip on the three dots in the upper right corner and select Sort → by size.
3. Delete or clear the data of the most “heavy” applications.

💡

If the internal memory is 90% or more full, the smartphone starts to slow down, optimally keep free 10-15% of the total volume.
