Xiaomi Redmi 7A owners often face a shortage of internal memory, especially if the device has been in use for several years. Even after cleaning the cache and removing unnecessary files, the system can issue a notification βMemory is fullβ, blocking the installation of new applications. One effective solution to this problem is to transfer applications to a memory card β but in MIUI this process has its own nuances.
The standard portability methods available in the newer versions of Android in the Redmi 7A may be limited or hidden, due to Xiaomiβs policy of optimizing external drives and firmware features. However, there are both official and alternative ways to free up space, from built-in MIUI features to third-party utilities. In this article, we will discuss all current methods, their pros and cons, and give recommendations for choosing the right microSD card for your smartphone.
Before you start moving, it is important to understand that not all applications can be moved to a memory card, system utilities, Google services and some games with anti-piracy protection (for example, PUBG Mobile or Genshin Impact will remain in internal memory. SD-The cards may be lower, especially if you use a cheap Class 4 or Class 6 drive.
1. Check the compatibility of the memory card with Redmi 7A
Before you port the application, make sure that your microSD card meets the requirements of Xiaomi Redmi 7A. The device supports cards up to 256 GB, but there are important nuances:
β Supported formats: FAT32 (up to 32GB) and exFAT (from 64GB). NTFS unrecognized.
β Speed class: Minimum Class 10 or UHS-I (U1) For stable application performance, Class Cards 4/6 can cause lag.
β Manufacturer: SanDisk, Samsung brands are recommended EVO, Kingston β They are less counterfeited and last longer.
To check the current format of the card, connect it to your computer through a card reader and see the properties in the conductor. If the card is formatted in NTFS, it will have to be reformatted to exFAT (data will be deleted!).
β οΈ Warning: Do not buy memory cards with suspiciously low prices (for example, "256 GB for 500 rubles"). Often these are fakes with real volume of 8-16 GB, which lead to data loss.
If you havenβt bought a card yet, look at the table below with price-to-volume recommendations for the Redmi 7A:
| Size of map | Class speed | Estimated price (2026) | What tasks are suitable for |
|---|---|---|---|
| 32GB | Class 10 / U1 | 300β500 β½ | Storage of photos, music, light applications |
| 64GB | UHS-I (U1/U3) | 600β900 β½ | Transferring most applications, games of medium weight |
| 128GB | UHS-I (U3) | 1 200β1 800 β½ | Complete replacement of internal memory, heavy games |
| 256GB | UHS-I (U3) / A1/A2 | 2 500β3 500 β½ | Maximum volume for Redmi 7A, suitable for professional use |
2.Official method: transfer via MIUI settings
Xiaomi Redmi 7A based on MIUI has built-in application portability, but it is hidden deep in the menu and does not work with all programs.
1. Open Settings β Applications β Application Management.
2. Select the application you want to transfer (for example, Telegram or VK).
3. Press the Warehouse button.
4. If the option is available, the Change option will appear - tap it and select Memory Card.
β Limitations of method:
- π΄ It only works with a few apps (usually those that support Adoptable Storage).
- π΄ System applications and games with protection (for example, WhatsApp, Banking applications) cannot be transferred.
- π΄ After the transfer, some of the data may remain in internal memory (cache, updates).
Make sure that the memory card is inserted and recognized by the system
Check the vacant space for SD-map (should be) β₯ scope)
Close the application that is planned to be transferred
Backup of important data (in case of failure)-->
If the Change button is inactive or not, the application does not support the transfer, in which case one of the alternative methods described below will help.
Alternative method: formatting the card as internal memory (Adoptable Storage)
This method allows you to combine the microSD card with the internal memory of the smartphone, after which the system will perceive it as part of the main storage.
Instructions:
1. Insert the memory card in Redmi 7A and wait for it to be recognized.
2. Go to Settings β Storage β Memory Map.
3. Click on the three dots in the upper right corner and select Storage Settings.
4. Tap format as internal and confirm the action.
β οΈ Warnings:
- π΄ All data on the map will be deleted without the possibility of recovery.
- π΄ The map will be encrypted and tied to this smartphone, and in another device it will have to be formatted again.
- π΄ Some apps (like Google Play Services) will still be in internal memory.
Once formatted, the system will automatically prompt you to transfer some of the data to the map, and you will also be able to manually move applications through Settings β Applications, as described in the previous section.
What if the option βFormat as internalβ is not available?
4. Application portability with ADB (for power users)
If standard methods don't work, you can use Android Debug Bridge (ADB), a debugging tool that lets you manually tell the system which apps to port, which requires a connection to your computer, but gives you more control.
Step-by-step:
1. Enable USB debugging on Redmi 7A:
- Go to Settings β About Phone β MIUI version and tap 7 times to activate Developer Mode.
- Return to Settings β Additional β For developers and enable debugging over USB.
2. Connect your smartphone to your PC and install ADB drivers (you can download from the official Google website or via Mi PC Suite).
3. Open the command line (Windows) or terminal (macOS/Linux) and type:
adb devicesIf the device appears in the list, enter:
adb shell pm set-install-location 2This command will force the system to install new applications on the default SD-map.
4. To transfer already installed applications, use:
adb shell pm move-package com.example.app /sdcard(Replace com.example.app with a real application package, such as com.whatsapp).
π‘
To find out the batch name of the application, install the App Inspector utility from Google Play or use the command adb shell pm list packages | grep "application name"
β οΈ Important: Not all apps support portability ADB. If the team returns a Failure error [NOT_MOVED: Operation not allowed, so transfer is not possible.
5. Use of third-party utilities for transfer
If you donβt want to mess with ADB or the built-in MIUI features donβt work, you can use third-party apps. Below are proven utilities that support Redmi 7A:
- π± AppMgr III (App 2 SD) β It shows you what applications you can transfer, and it does it in one tap.
- π± Link2SD β Creates symbolic links to transfer some data to the map (requires root rights).
- π± Files by Google β does not tolerate applications, but helps to clear unnecessary files, freeing up space.
β οΈ Warning: Appendices like Link2SD require root access, which voids warranty and can lead to unstable operation of the smartphone. Use them only if other methods have not helped.
How to work with AppMgr III:
1. Install the app from Google Play.
2. Open it and give access to the storage.
3. In the list of applications, tap the one you want to move.
4. Press Move to SD Card (if the button is active).
Itβs worth noting that even with these utilities, some apps (like Facebook or Instagram) may refuse to be ported due to developer restrictions.
6.Memory optimization without application portability
If porting apps doesnβt help or isnβt possible, try alternative ways to make room on the Redmi 7A:
- π§Ή Cache Clearing: Go to Settings β Warehouse β Clean and delete unnecessary temporary files.
- π Media Transfer: Photos, videos and music can be manually moved to a memory card via Explorer or Google Files.
- ποΈ Removing duplicates: Applications like CCleaner or SD Maid finds repeating files.
- βοΈ Cloud Storage: Move rarely used files to Google Drive, Yandex Disk or Mi Cloud.
It is also necessary to disable the automatic saving of media files in messengers:
β WhatsApp: Settings β Storage β Autoupload media β turn off for mobile data.
β In Telegram: Settings β Data and Memory β Autoboot Media β Select Never.
If there is critically little space (less than 500MB), MIUI can start to brake, in which case the factory reset will help (donβt forget to back up!).
7. Frequent errors and their solutions
When transferring applications to a memory card, Redmi 7A users often face problems, and we will analyze the most common and ways to eliminate them:
| Mistake. | Possible cause | Decision |
|---|---|---|
| The "Transfer" button is inactive | The application does not support portability or the card is formatted as portable | Try formatting the card as an internal one or using ADB |
| The application has been moved, but it is not running | Memory card too slow (class below Class 10) | Replace the card with a faster one (UHS-I U3) |
| After the transfer, the application flies out | Some of the data is stored in internal memory and the connection with it is lost. | Remove and reinstall the application by selecting the memory card as the installation location |
| The system does not see the memory card | The card is damaged, incompatible or incorrectly inserted | Check the card on another device and format it in FAT32/exFAT |
If your smartphone starts to slow down after transferring applications, try to return the most resource-intensive programs (games, social networks) to internal memory, and also make sure that at least 10% of free space remains on the card, which is necessary for the stable operation of the file system.
