Owners of Xiaomi Redmi 7A Often, they face a lack of internal memory, especially if there are many applications or games installed on the device, and one way to solve this problem is to transfer some programs to the device. SD-But in Redmi. 7A (As with many Xiaomi budget smartphones, this feature works with limitations that the manufacturer does not always warn about.
In this article, we will not only explore the standard way to migrate through settings, but also alternative methods for applications that do not want to move, you will learn which programs can be transferred without risking system stability, and which are better left in internal memory, and we will analyze typical errors (for example, โNot enough space on the mapโ or โTransfer is impossibleโ) and propose working solutions.
Important: the procedure for transferring to Redmi 7A It is different from newer Xiaomi models (e.g. Redmi Note 10 or Xiaomi). POCO X3), It's a place where Adoptable Storage is used, and it's the old way, with manual application selection and partial support. If you use a memory card of a class of 10 or higher, the chances of success are higher, but even in this case, some applications (for example, instant messengers or system utilities) will not be able to transfer.
Why at Redmi? 7A Not all applications can be transferred to SD-map
The main reason for the restrictions lies in the architecture of Android Go, on the basis of which Redmi works. 7A. This lightweight version of the OS is optimized for weak devices, but has a number of strict limitations:
- ๐ System applications (e.g. Settings, Phone, Messages) are locked for transfer โ they must remain in internal memory for stable operation.
- ๐ Widget applications (such as Weather or Calendar) often do not support portability, as widgets require quick access to data.
- ๐ Games and programs that use OBB-files (additional data) may not work properly after transfer: PUBG Mobile, Asphalt 9.
- ๐ Some apps (such as WhatsApp or Telegram) block the transfer for security reasons โ their data is stored in encrypted form.
Besides, Redmi. 7A It does not support Adoptable Storage technology (conversion) SD-The card is part of the internal memory that is available on newer Xiaomi devices, which means that the memory card will only be used as external storage, not as an extension of the main memory. Ported applications may slow down, especially if you use a Class 4 or 6 card.
โ ๏ธ Note: If you are moving the application to SD-If you take the card out, the program stops working until the card is inserted back, and that's even for messengers, you can't get messages until the card is connected.
Preparation SD-maps: formatting and compatibility checks
Before transferring applications, you need to properly prepare the memory card.Redmi 7A It supports cards up to 256GB, but for stable operation, it is recommended to use cards up to 128GB of a class of 10 or higher:
- Check the file system: The map must be formatted in FAT32 Or exFAT. If you're using a card that's over 32 GB, FAT32 It may not be appropriate โ choose exFAT.
- Formatting via phone: Insert the card in Redmi 7A, Go to Settings. โ Warehouse โ Map. SD and choose Format as internal storage (if available) or Format as portable.
- Check the speed: Use the app A1 SD Bench (available on Google Play) to measure read/write speeds. Apps are recommended to be at least 20MB/s for portability.
If you've already used the card on another device, you'd better format it again.
- Connect the card to the PC through the card reader.
- Open this computer (Windows) or Disk utility (macOS).
- Select a map, right-click and select Format.
- Specify the exFAT file system (for cards) >32 GB FAT32 (map <32 GB).
| Type of card | Max. Volume. | Recommended file system | Suitable for app transfer? |
|---|---|---|---|
| MicroSD (Class 4) | 32GB | FAT32 | โ No (low speed) |
| MicroSD (Class 10) | 128GB | exFAT | โ Yes. |
| MicroSDXC UHS-I | up to 256GB | exFAT | โ Yes (optimally) |
| MicroSD (fake) | anyone | โ | โ No (risk of data loss) |
โ ๏ธ Note: If you bought a memory card at a suspiciously low price (e.g., a card for your computer,"256 GB for 500 It's probably a fake. These cards often have real volumes. 2โ4 It's less than what you're saying and it can damage your data. H2testw (Windows or F3 (macOS/Linux).
Standard method: transfer via phone settings
If your app supports portability, you can do it through the Redmi menu. 7A. Here's the step-by-step instruction:
- Open the Settings โ Applications.
- Select the All Apps tab and find the one you want (like Facebook or Facebook). VK).
- Slip on the name of the application, then select Warehouse.
- Click Change (or Move to) SD-card if the button is active).
- Confirm the action and wait for the process to be completed.
If the button is moved to SD-The card is inactive (grey), which means that:
- ๐น The app does not support transfer (see list at the beginning of the article).
- ๐น Memory card formatted incorrectly or damaged.
- ๐น There is not enough free space on the map (at least 1.5-2 times more than the weight of the application itself is required).
After the transfer, some of the application data will remain in internal memory (usually cache and temporary files). To free up space completely, manually clear the cache:
- Return to the App Store menu.
- Click Clear Cache and Clear Data (if necessary).
The button "Move to the SD-map active|There is enough free space on the map (minimum) 2 GB)|The map is formatted in exFAT/FAT32|The application is not a system application-->
Alternative methods: transfer through ADB and third-party utilities
If the standard method doesnโt work, you can try to migrate the app using Android Debug Bridge (ADB). This method requires connecting the phone to a PC and basic command line knowledge, but allows you to bypass some system limitations.
Here's what you're gonna need:
- ๐ฅ๏ธ Computer with Windows/macOS/Linux.
- ๐ USB-cable (preferably original).
- ๐ฆ Installed Xiaomi drivers (you can download from the official website).
- ๐ ๏ธ Tool. ADB (is part of Android SDK Platform-Tools).
Instructions for transfer via ADB:
- Turn on the phone Developer Mode: go to Settings โ About phone and 7 times tap on the item MIUI version.
- Return to Settings โ Additional โ For developers and enable USB debugging.
- Connect the phone to the PC and confirm the debugging permission.
- Open the command line (Windows) or terminal (macOS/Linux) and type:
adb shell pm set-install-location 2This command forces the system to install new applications on the SD-To transfer an already installed application (for example, Instagram), use:
adb shell pm move-package com.instagram.androidReplace com.instagram.android with your appโs batch name (you can find out through App Inspector or Google Play).
โ ๏ธ Note: Some applications after transfer through ADB They can run unstablely or stop running altogether, especially with protected games (such as Clash of Clans or Brawl Stars). ADB Make a backup copy of the data!
If ADB It seems too complicated, you can try third-party utilities:
- ๐ฑ AppMgr III (App 2 SD) โ Allows you to transfer applications and clear the cache.
- ๐ฑ Link2SD โ Creates symbolic links for data transfer (requires root rights).
- ๐ฑ Files by Google โ helps you analyze occupied space and delete unnecessary files.

Which apps can be carried without risk and which ones canโt.
Not all programs work equally well after the transfer to the SD-Below is a table of recommendations for popular categories:
| Category of annex | Examples | Can I move it? | Risks. |
|---|---|---|---|
| Social media | Facebook, VK, Twitter | โ Yes. | They can be slower to download media files. |
| Messengers | WhatsApp, Telegram, Viber | โ No. | Loss of messages when retrieving the card |
| Games (no) OBB) | Candy Crush, Subway Surfers | โ Yes. | Possible lags with high load |
| Games (c) OBB) | PUBG Mobile, Genshin Impact | โ No. | The game will not start or will fly out. |
| Multimedia. | YouTube, Spotify, MX Player | โ Yes. | Buffering may slow down |
| System utilities | Lantern, Calculator | โ No. | They may stop working after the update. |
Critical information: Applications that sync data in the background (such as Google Photos or Dropbox) after transferring to the Internet SD-This is because Android limits background activity for programs installed on external storage.
If you moved the app but it got worse, return it:
- Open the Settings โ Applications.
- Select the problem app โ Storage.
- Press Transfer to the internal memory.

Before transferring the game, check if it has any OBB-To do this, open the file manager and go to the folder. Android/obb. If there is a folder with the name of the game, transfer is impossible.
Transfer errors and their solutions
When you try to transfer the application to SD-map 7A Users often encounter errors. Let's look at the most common ones and how to fix them:
1 "Insufficient space on the map"
This error occurs even if there is a free space on the map.
- ๐ธ The map is formatted in FAT32, which does not support files larger than 4 GB. Solution: reformat to exFAT.
- ๐ธ The application requires continuous space, and the map is fragmented. Solution: copy all the data from the card to the PC, format it, and return the files back.
- ๐ธ There are hidden system files on the map (e.g. from the camera) so you can delete them or transfer them to your PC.
2 "Transfer impossible"
This error means that the application is blocked for portability.
- ๐ธ Try to move it through. ADB (see the instruction above).
- ๐ธ Install the Lite version of the app (e.g. Facebook Lite instead of the regular Facebook).
- ๐ธ Use the function of Cloning applications in Settings โ Annexes โ Cloning of applications (available in MIUI 12+). The clone can be transferred to SD-map.
3.The app flies out after the transfer
If the program stops working:
- ๐ธ Put it back in your internal memory (see the instructions above).
- ๐ธ Clear the cache and app data.
- ๐ธ Reinstall the application by selecting internal memory as storage location when installing.
4. Memory card not determined
If the phone can't see SD-map:
- ๐ธ Remove the card and insert it back.
- ๐ธ Check the card on another device (for example, on a PC).
- ๐ธ Format the card in exFAT via a computer.
- ๐ธ Update your phone: Go to Settings โ The phone. โ Updating the system.
