Xiaomi Redmi 7A has proven itself as a reliable budget device, but its internal storage capacity of 16 or 32 GB is quickly filled with modern applications and media.
When the free space runs out, the system starts to run slower, and installing new programs becomes impossible without deleting old data.
In this guide, we will discuss current methods for transferring applications to an external drive, taking into account the features of the MIUI shell and the limitations of the Android operating system.
You will learn not only about regular funds, but also about more advanced ways to maximize the use of resources of your device.
Why is there a lack of memory in the Redmi 7A?
The main reason for storage overflow is the growing size of modern applications that require more and more resources to work.
Software developers often do not optimize their products for budget models, leaving behind gigabytes of cache and temporary files.
Android system partitions also take up a significant portion of the available space, leaving the user with only half of the declared volume.
⚠️ Warning: Constant operation of the system with a filled storage (less than 500 MB free) can lead to critical errors and loss of personal data.
Using a microSD memory card becomes not just a convenient option, but a necessity for comfortable operation of the smartphone.
Preparation of the memory card for work
Before you start transferring data, you need to make sure that your memory card meets the requirements of speed and reliability.
For stable application performance, it is recommended to use Class 10 or higher speed cards such as UHS-I.
A slow read and write speed can cause applications to run for a long time or run with errors.
💡
Use memory cards up to 128GB for maximum compatibility with the Redmi 7A, although officially supported up to 256GB.
Insert the card into the slot and wait for the system notification about the successful connection of the new media.
If the card has been used in another device before, it is better to format it to avoid file system conflicts.
- 📱 Make sure your smartphone is turned off before removing or installing the card.
- 💾 Save important files from card to computer before formatting.
- 🔍 Check the card for errors using the chkdsk utility on PC.
- ⚙️ Use only the original microSD card adapter if you need it.
The standard method of transfer through settings
The MIUI shell provides basic storage management functionality that allows you to move some applications.
However, it is worth noting that not all programs support this feature due to the limitations imposed by Google developers.
To start, go to your device’s settings menu by finding the appropriate icon on your desktop.
Settings → About the phone → StorageIn the menu that opens, select the item responsible for managing internal memory and SD-card.
☑️ Pre-transfer check
The system will show the list of installed programs and the amount of space they occupy, allowing you to select the target object for transfer.
If the transfer button is active, click on it and wait for the data copying process to be completed.
⚠️ Note: After the application has been moved to SD-Map widgets and shortcuts may temporarily disappear from the desktop before rebooting.
In some cases, the system may prohibit the transfer, citing instability of the program from an external medium.
Use of Adoptable Storage
A more radical and effective method is the Adoptable Storage feature, which was introduced in Android 6.0.
It allows you to format the memory card so that the system will perceive it as part of the internal storage.
This makes it possible to install applications on the default map, bypassing many of the limitations of standard portability.
Risks of using Adoptable Storage
To activate this feature on Xiaomi, you often need to enter special commands through USB debugging.
First, you need to activate the developer mode by quickly clicking on the build number several times in the About Phone section.
Settings → About phone → 7 times press on "Version MIUI"Then in the menu for developers, include the item “Debugging by” USB» computer-communicate.
After connecting to the PC and installing ADB drivers, you can execute a formatting command.
| Parameter | Meaning/Description | Recommendation |
|---|---|---|
| ADB Team Team | pm set-install-location 2 | Sets SD as a Priority |
| Formatting | sm partition | Requires root rights or ADB |
| Speed of the map | Min 10 MB/s | Critical for system speed |
| Compatibility | Android 6.0+ | It's powered by Redmi 7A. |
Once the command is executed, the card will be formatted and integrated into the system as internal memory.
All new applications will be automatically installed on an external drive, freeing up space inside.
Application limitations and compatibility
Despite all efforts, some apps flatly refuse to move to an external drive.
This is due to the security policy of Google Play and the peculiarities of the system services.
Messengers, banking applications, and desktop widgets often require placement solely in internal memory.
Attempts to force the transfer of such programs may lead to their incorrect operation or complete refusal to start.
⚠️ Note: System applications such as Phone, Messages and Camera cannot be ported - this can disrupt the entire smartphone.
The user must independently assess the importance of each application before moving it.
For games with a large cache volume, transfer is often available and helps to free up space significantly.
💡
Not all applications can be portable: system and mission-critical services must remain in internal memory for system stability.
Alternative ways to free up space
If application portability is not possible or insufficient, you should pay attention to other methods of optimization of storage.
Cleaning the app cache, deleting downloaded files, and using cloud storage can give you quick results.
The Security app in MIUI has a built-in tool for deep cleaning garbage files.
- 🗑️ Regularly clean the Downloads folder of old documents and pictures.
- ☁️ Use Google Photos to store your media library in the cloud with compression.
- 💬 Delete your messaging history, especially your videos and files.
- 📲 Remove unused apps that you haven’t used in more than a month.
You can also change the camera settings to save photos and videos immediately to the memory card.
Open the Camera app, go to the settings and select "Save to" SD-map».
This will allow you to save heavy 4K or Full HD video files directly to an external medium, bypassing internal memory.
