How to install applications SD-Xiaomi Redmi 8: All the ways

Xiaomi Redmi 8 owners often face a lack of internal memory, especially if the device is used to store photos, videos and many applications. SD-But in the MIUI (Xiaomi’s shell feature doesn’t work as clearly as it does on pure Android. In some cases, the system even hides the possibility of transfer, offering instead to clear the cache or delete unnecessary files.

In this article, we will discuss all available ways to install applications on SD-map 8 — From standard settings to hidden features and workarounds. You will learn which applications can be ported and which remain “tied” to internal memory, how to format the memory card correctly for maximum compatibility, and what to do if the system produces an error “Not enough space” despite the free space on the computer. SD. We will also look at the unique limitations. MIUI 12/13/14, Not documented in Xiaomi’s official instructions.

Why Redmi 8 doesn't see why SD-map as an internal memory?

The main problem when transferring applications to SD Redmi 8 is about politics. MIUI And the limitations of Android. Starting with Android 6.0 Marshmallow, Google introduced the concept of Adoptable Storage, which is the ability to format. SD-However, Xiaomi deliberately disabled this feature in its firmware, citing security and stability reasons.

Here are the key reasons why app portability may not work:

• 📱 Limitations MIUI: There is no option to “Format as internal memory” in the settings, even if the card supports high speed classes (UHS-I, U3).
• 🔒 Data protection: Xiaomi blocks the portability of Google system applications and services (such as Google Play Services) as this may disrupt the device.
• 🛠️ File system incompatibility: Maps formatted in exFAT or NTFS, Do not support the installation of applications – required FAT32 (but with a 4GB file size limit).
• 📦 Developer restrictions: Some applications (such as instant messengers or bank clients) explicitly prohibit porting to the Internet. SD manifesto.

It is important to understand that even if you manage to migrate the app, its performance may fall. SD-cards (even class) A2) The memory is slower than the internal memory of the eMMC 5.1, which is equipped with Redmi 8, this is especially noticeable in games and "heavy" applications such as photo editors.

Preparation SD-Maps: Formatting and Selection of File System

Before trying to transfer applications, you need to properly prepare SD-It depends on whether you can actually use it to install software:

1. Check the card speed class. Class A2 or UHS-I U3 is recommended for application installation. Class A1 or Class 10 cards can run slowly.
2. Back up the data. Formatting will destroy all the files on the map.
3. Select the file system: 🔹 FAT32: Compatible with most devices, but limited to files up to 4GB. Not suitable for modern games. 🔹 ExFAT: Supports large files but does not allow you to install applications. 🔹 Ext4: Optimal for Android, but Redmi 8 doesn’t support it out of the box".

For formatting in FAT32 (if the card is larger than 32 GB), you can use:

• 🖥️ Windows built-in tools (via Disk Management), but only for cards up to 32 GB.
• 🛠️ Third-party utilities such as GUIFormat or Fat32Formatter (map 64/128 GB).
• 📱 Redmi 8 Device itself via Settings → Warehouse → SD-map → Format.

💡

If the card is undetectable after formatting, try disabling it in the storage settings, retracting it and pasting it back in again, sometimes rebooting the device helps.

⚠️ Note: If you format the card as internal memory through third-party tools (e.g, ADB), This can lead to the loss of warranty on the device. Xiaomi does not officially support such a method.

Method 1: Transfer applications through standard MIUI settings

The simplest, but also the most limited, method, it only works for applications that explicitly support SD portability. Here's how to do it:

1. Open Settings → Applications → Application Management.
2. Select the app you want to migrate (like Facebook or Spotify).
3. Click on Warehouse.
4. If the option is available, you will see the Change or Move button. SD-Press it.
5. Confirm the transfer and wait for the process to be completed.

Limitations of this method:

• 🚫 It only works for a part of the applications (usually games and lightweight utilities).
• 🔄 Google System Applications and Services Cannot Be Moved.
• 📥 Only a portion of the data is transferred (cache and some files remain in internal memory).

If there is no transfer button, this means that:

• 📌 The app does not support portability (such as WhatsApp or Google Maps).
• 📌 The map is formatted in exFAT/NTFS.
• 📌 Application Protection feature is included in MIUI (You need to turn off the settings. → Special facilities → Application protection).

Method 2: Use of the SD-Cards as internal memory (hidden function)

While Xiaomi has officially removed the option of formatting SD as internal memory, in some versions of MIUI (especially Android 9/10) it can be activated via ADB (Android Debug Bridge), a method that requires a computer connection and basic command line knowledge.

Here's the step-by-step instruction:

1. Turn on Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI until the notification "You're a developer" appears.

USB debugging

Settings → Additional → For Developers

sm list-disks

You should see a line like this. disk:179,XX (where XX — number SD-map).

sm partition disk:179,XX private

After completion, restart the device. SD-The card will be part of the internal memory.

Advantages of this method:

• ✅ The ability to install any application on SD (game).
• ✅ The card is encrypted and linked to the device (it won’t work on other phones).

Disadvantages:

• ⚠️ All data on the map will be deleted without the possibility of recovery.
• ⚠️ Application speed may decrease (depending on class) SD-map).
• ⚠️ When you remove the map, some applications will stop working.

⚠️ Note: After formatting SD It's not going to be retrievable and used on other devices without completely erasing the data. MIUI, if the card suddenly turns off (for example, due to poor contact).

Method 3: Transfer applications using third-party utilities

If the standard methods don’t work, you can use third-party apps from Google Play.

• 📌 AppMgr III (App 2 SD) — Shows you which apps you can transfer and does it in one click.
• 📌 Link2SD — It allows you to create symbolic links for data transfer (requires root rights).
• 📌 Files by Google – has a built-in function to clean and transfer files (but not all applications).

Example of AppMgr III:

1. Install the app from Google Play.
2. Open it and provide all the necessary permissions.
3. In the list of applications, find those who have a tick in the column "Transfer" ✅.
4. Click on the app and select Move to SD-map.

Restrictions of third-party utilities:

• 🔒 Most of them can’t get around the restrictions. MIUI system-application.
• 🛠️ For full transfer (for example, through the Link2SD) Root is required, which deprives of guarantees.
• 📦 Some applications may not work as well after the transfer (for example, notifications stop coming).

💡

Third-party utilities cannot port Google system applications and services; they are only useful for user programs that initially support the port.

Solving common errors when transferring to SD

When you try to move applications to SD-Redmi 8 card users often encounter errors. Here are the most common ones and how to fix them:

If after the transfer the application stopped working:

• 🔄 Try clearing the app cache in the settings.
• 📥 Transfer it back to your internal memory.
• 🔧 Install an app update (sometimes this solves the compatibility issue).

Particular attention should be paid to the error. -24. It often occurs when you try to transfer the application that uses it. OBB-files (e.g. games of type) PUBG Mobile or Call of Duty:

1. Download the OBB file to internal memory.
2. Move the application itself to SD.
3. Manually move the OBB folder to the map in Android/obb/.

Alternative ways to free up memory in Redmi 8

If the applications are transferred SD-The card is not helped or impossible, consider alternative methods of releasing internal memory:

• 🧹 Cache Clearing: Go to Settings → Warehouse → Clean. Select Clear App Cache (up to a few gigabytes can be deleted).
• 🗑️ Remove Unnecessary Files: Use the Built-in Cleanup Utility MIUI Files by Google, remove duplicate photos/videos (e.g. through Gallery) → Albums. → Duplicate).
• ☁️ Transfer media to the cloud: Set up an automatic upload of photos to Google Photos or Mi Cloud. After downloading, delete local copies (Option Free up space in Google Photos).
• 🔄 Use Lite versions of apps: Replace Facebook with Facebook Lite, Messenger with Messenger Lite, etc. Lite versions weigh in on Facebook. 2-5 Less and consumes less resources.

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

1. Go to Settings → Applications → Application Management.
2. Sort the list by size (click on the three dots in the top right corner → Sort by size).
3. Remove or transfer the most “heavy” applications to SD.

If the internal memory is 90% or more full, the system starts to slow down, in which case even transferring applications to SD may not help - it is better to free at least 2-3 GB manually.
