Transfer of applications to SD-map 7A: guide

Xiaomi Redmi 7A — budget smartphone with limited internal memory (16 or 32 GB), which is quickly filled with applications and media files. SD-The card seems like a logical solution, but in Android (especially on devices with a mobile phone). MIUI) Unlike older versions of the operating system, where the memory card could be formatted as internal storage, Redmi has a nuanced process. 7A s MIUI 10/11/12 Not all options are available.

In this article, we will discuss all working methods for transferring applications to SD-map, including standard settings MIUI, utilization ADB We also explain why some programs can't be ported, and how to get around manufacturer restrictions. If you're running into a memory problem or want to optimize storage, this guide is for you.

Why at Redmi? 7A You cannot transfer all applications to SD-map?

The main problem lies in the policy of Google and Xiaomi: since Android 6.0 Marshmallow, the portability of applications to external drives has been limited for security and performance reasons. Redmi 7A (with Android 9 Pie and MIUI) has additional restrictions:

• 🔒 Secure applications (banking, instant messengers, system) cannot be ported – they require quick access to internal memory.
• ⚡ Productivity: SD-cards (even class) A1/A2) They work slower than the internal memory, which can cause lags.
• 📱 MIUI-Restrictions: Xiaomi blocks portability for certain software categories (e.g., widgets or Google services).
• 🔄 Updates: After the system update, the transferred applications can “fly” back to internal memory.

However, some programs (games, utilities, some social networks) can be moved.

Method 1: Standard Transfer through MIUI Settings

The easiest method is to use the built-in MIUI function, which is suitable for most custom applications, but does not work with system utilities.

1. Open Settings → Applications → Application Management.
2. Select the app you want to migrate (like Facebook or Spotify).
3. Slip on Warehouse.
4. If the option is available, click Change and select SD-map.
5. Confirm the transfer and wait until it is completed (may take a few minutes).

⚠️ Note: After porting, some features of the application (such as notifications or widgets) may not work properly!

Method 2: Formatting SD-maps as internal memory

This method allows the memory card to be used as part of the main storage, but has critical drawbacks:

• 🔄 The card cannot be retrieved without losing data (it will become "tied" to the phone).
• 📉 The speed of the system may fall (SD-cards slower than internal memory).
• 🚫 Not all applications will work correctly (especially system applications).

If you are prepared for the risks, follow the instructions:

1. Put it in. SD-card to slot (cards up to 256 GB are supported).
2. Go to Settings. → Warehouse → SD-map.
3. Slip on the three dots in the top right corner and select Storage Settings.
4. Click Format as Internal and confirm the action.
5. After formatting, restart the phone.

Important: After this operation, the card will not be used on other devices without completely erasing the data, and some applications (such as WhatsApp or Google Maps) may refuse to work.

Method 3: Transfer over ADB (for power users)

If standard methods don't work, you can use ADB (Android Debug Bridge), a debugging tool, which allows you to migrate even those applications for which the option is blocked in MIUI.

🔹 Requirements:

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 Included debugging by USB redmi 7A (Settings → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers → Debugging by USB).
• 💾 SD-A card formatted as a portable storage.

📌 Instructions:

1. Connect your phone to your PC and start ADB (for example, via Platform Tools).
2. Enter the command to check the connection: adb devices (should display the serial number of the device).
3. Find out the batch name of the app (for example, for Facebook it is com.facebook.katana).
4. Run the port command: adb shell pm set-install-location 2 (this will force the system to install new applications on the device). SD-default-card).
5. To transfer the installed software, use: adb shell pm move-package com.facebook.katana (replace com.facebook.katana with the desired package).

⚠️ Note: Not all applications support this method. If you see a Failure error after the command, [INSTALL_FAILED_INVALID_INSTALL_LOCATION], transferability.

💡

Before using ADB, back up your data via Settings → Additional → Backup and Reset. Errors in commands can cause system failures.

Comparison of transfer methods: which one to choose?

For most users, the best solution is a combination of standard portability (for supported applications) and cache cleaning (Settings → Storage → Clean). The ADB method is suitable for experienced users, and formatting SD as internal memory should only be used as a last resort.

What to do if the transfer does not work?

If you have followed the instructions but the apps are not portable, check the following points:

• 📌 Type SD-Cards: Use class cards A1 or A2 (For example, SanDisk Ultra A1). Class cards C10 or UHS-I without marking A may not be suitable.
• 🔧 Updates MIUI: In some versions of the firmware, the port option is disabled. → The phone. → Updating the system.
• 🚫 Application restrictions: some programs (such as Google Play Services or Mi Account) cannot be ported.
• 🔄 Reboot: Reboot your phone after the transfer – sometimes changes only apply after the reboot.

If nothing helps, consider alternative solutions:

• 🗑️ Cache cleaning: in Settings → Storage Press “Clean” to vacate the space.
• ☁️ Cloud Storage: Move your photos/video to Google Photos or Mi Cloud.
• 📲 Lite versions of apps: Use lightweight versions of social networks (for example, Facebook Lite or Messenger Lite).

💡

If SD-The card is defined as damaged, format it via PC (in format) FAT32 or exFAT) before reuse on the phone.
