How to transfer applications to the memory card in Xiaomi Redmi Note 4: all ways + limitations

Xiaomi Redmi Note 4 It is still a popular smartphone due to its balanced performance and reliability, but its main drawback is the overall value of the smartphone. 16/32/64 GB of internal memory in basic versions. Over time, users face a lack of space, especially if they are actively installing games and applications. MIUI This process is nuanced.

Unlike the newer Xiaomi models, where the application portability function is often blocked by the manufacturer, the Redmi Note 4 (based on Qualcomm Snapdragon 625) still supports this feature, but with limitations. In this article, we will discuss all the working methods: from standard MIUI settings to manual transfer via ADB, and explain why some applications can not be moved to a memory card.

Important: the procedure depends on the MIUI version (8 to 14) and the type of memory card (regular FAT32 or formatted as internal memory).We tested all methods on the MIUI 10-12 firmware, the most relevant for the Redmi Note 4 in 2026.

1.Preparation: Which memory card is suitable for transferring applications

Not every microSD will allow you to migrate applications. Three parameters are critical for the Redmi Note 4:

• 🔹 Speed class: minimum class 10 (UHS-I U1). Class Cards 4/6 They will slow down applications.
• 🔹 Volume: from 16 GB (but better 32 GB)+, As the system reserves a portion of the memory).
• 🔹 Formatting: For a full application transfer, the card needs to be formatted as internal memory (this erases all data!).

If you plan to use the card only for storing files (photos, music), FAT32 or exFAT format is enough. But to transfer applications you will need to force formatting through your phone settings - more about this in the next section.

⚠️ Note: Once formatted as internal memory, the card cannot be read on other devices (PCs, cameras) without completely erasing the data, and the card will be encrypted, as if the phone were reset to factory settings, access to the data on it will be lost.

Method 1: Formatting the card as internal memory (official method)

This is the easiest way to run MIUI 8-12 without root rights, and the bottom line is that Android formats the map as part of the internal storage, and the system automatically suggests that you transfer applications to it.

Step-by-step:

1. Insert the memory card into the Redmi Note 4 slot (hybrid slot – if you use 2 SIM, one will have to be removed).
2. Go to Settings. → Memory.
3. Slip on the Memory Card item (or SD-map).
4. In the upper right corner, press three dots (⋮) and select Storage Settings.
5. Select Format as Internal → Erase and Format.
6. After formatting (it takes 1-3 minutes), restart the phone.

Once the system is restarted, it will suggest moving some of the data to the map, but not all applications can be moved, and many (especially system and cache games) will remain in internal memory.

⚠️ Warning: If the phone starts to brake after formatting, the map is probably too slow. UHS-I U3 or roll back changes to Settings → Memory. → Memory map → Data portability → Shut down.

Method 2: Manually transfer applications through MIUI settings

If the card is already formatted as internal memory, you can manually transfer supported applications:

1. Open the Settings → Applications.
2. Select the application you want (such as Telegram or VK).
3. Slip on Warehouse.
4. If the option is available, click Change → select Memory Card.
5. Confirm the transfer (may take a few minutes).

💡

If the Change button is inactive, the app does not support the transfer. Try clearing its cache (Settings → Apps → Storage → Clear cache) and try again.

List of applications that can usually be transferred:

• 📱 Messengers: Telegram, Viber, WhatsApp (but not cache!).
• 🎵 Music Players: Spotify, VK Music.
• 📖 Readers: Moon+ Reader, FBReader.

These applications cannot be moved:

• 🎮 Heavy-graphics games (PUBG, Genshin Impact – They require fast internal memory).
• 🔒 System applications (Settings, Phone, Google Play Services).
• 📷 Camera applications (they only work with internal memory).

💡

Even if the app is ported to the card, its updates and cache can automatically be stored in internal memory.

Method 3: Transfer over ADB (for power users)

If standard methods didn’t work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to force apps to the map, which works even for programs that don’t support porting over settings.

What you need:

• 🖥️ Computer with Windows/Linux/macOS.
• 🔌 USB-cable (preferably original).
• 📦 Installed drivers ADB and Fastboot for Xiaomi.
• 🔧 Included debugging by USB phone-on.

Instructions:

1. Turn on Developer Mode on Redmi Note 4: Settings → About Phone → MIUI Version (Tap 7 times)

⚠️ Note: Not all applications work properly after forced porting through ADB. Some may crash or lose data. Backup before the procedure!

5 Why some apps can't be moved to the map

Even after all the manipulations, some of the apps will remain in internal memory, due to Android restrictions and developer policies:

• 🔒 Data protection: Payment applications (SberBank, Google Pay) are not portable for security reasons.
• 🎮 Performance: Games and applications with high read/write speed requirements (e.g, PUBG Lightroom or Lightroom) blocks the transfer, as the microSD is slower than the internal memory of eMMC 5.1 in Redmi Note 4.
• 📱 System Limitations: Applications integrated into MIUI (Topics, Security, do not support default portability.
• 🔄 Updates: Even a ported application can automatically update to internal memory if the developer has banned storage for the app. SD.

• 🗑️ Remove the application cache (Settings) → Memory. → Cash).
• ☁️ Transfer your photos/video to the cloud (Google Photos, Mi Cloud).
• 🔄 Use the Cleanup function in MIUI Security to remove unnecessary files.

-->

On the Redmi Note 4 with 16 GB of memory, these measures can free up to 3-5 GB – this is enough to install several new applications.

Alternative solutions: if the transfer has not helped

If none of these methods solve the problem of memory deficiency, consider these options:

• 🔧 Root access + Link2SD: Annex Link2SD It allows you to force the app to the map, creating symbolic links, requires unlocking the bootloader and root, which cancels the warranty.
• 📱 Factory reset: If the phone is clogged with unnecessary files, a full reset can free up to 10-15 GB!
• 🔄 Firmware Update: Some custom firmware (e.g. LineageOS) have removed application port restrictions.
• 💾 Use of the OTG-Driver: Connect the flash drive through OTG-Cable and transfer media files to it.

⚠️ Attention: Unlocking a bootloader on Xiaomi is associated with risks: Loss of warranty. Possible breech (turning your phone into a brick) if you make a mistake. Problems with Google Pay and other services that require SafetyNet.

7. Frequent errors and how to fix them

When transferring applications to a memory card, Redmi Note 4 users often face these problems:

💡

If the app stopped sending notifications after the transfer, check its settings. Some apps (such as WhatsApp) require reconfiguring notifications after moving to the SD.
