Owners of budget smartphones like the Xiaomi Redmi 7A often face a critical shortage of free space in internal memory.The MIUI operating system, even in its lighter versions, takes up a significant amount of space, leaving the user only a small fraction of the claimed 16 or 32 GB. When the built-in storage is overflowing, the phone starts to run slowly and new apps refuse to install, requiring an immediate solution to the problem.
Fortunately, the Redmi 7A supports microSD card installations, which theoretically extends the available space. However, standard Android settings and the MIUI shell often block direct installation of programs on an external drive for security and stability of the system. To get around these limitations and actually free up internal memory, you need to resort to more advanced customization methods, which we will discuss in detail later.
In this article, we will not only explore the standard portability paths available on the menu, but also the hidden features of the system. You will learn how to use debugging mode and computer utilities to force data to move. Proper file organization will allow you to install more games and social networks without removing old photos and music.
Preparation of memory card and smartphone for work
Before trying to transfer any data, you need to properly prepare the drive. Using a poor-quality or incorrectly formatted card can lead to data loss or malfunctions in the Redmi 7A. It is recommended to use cards of the speed class at least Class 10 or the UHS-I standard, since old and slow drives will significantly slow down the launch of applications.
Insert a microSD card into a smartphone slot and wait for the system to notify you. MIUI will suggest using the drive as a portable storage device or as internal memory. For our purposes, the most secure and stable option is to choose a portable storage mode, which will allow the system to correctly index files without the risk of completely blocking the card when resetting the phone.
⚠️ Note: Formatting a memory card will completely destroy all data on it. Be sure to back up photos and documents on your computer before you start the setup procedure.
After formatting, check that the phone sees a new volume. → Memory and make sure the volume of the external SD-If the system is unstable after inserting the card, try to remove it, wipe the contacts and insert again before the characteristic click.
Standard method of transfer through MIUI settings
The first step that every user should take is to use the built-in shell functionality. Not all applications support portability, but many games and heavy programs allow you to move some of your data to an external medium. To begin, open Settings → Applications → All applications and select the desired program from the list.
In the menu of the selected application, find Memory or Storage. If the program supports transfer, the "Change" or "Move to" button will be active. SD-You click on it, you start the system file migration process, and the duration of the operation depends on the size of the application and the speed of your memory card.
- 📱 Open the settings of a specific application in the program management menu.
- 💾 Find the memory usage section and click the storage change button.
- ⏳ Wait for the process to be completed without turning off the smartphone screen.
- 🔄 Repeat the procedure for all heavy games and social media.
It is worth noting that after updating the system or the application itself, the data can automatically return to internal memory, in which case the procedure will have to be repeated. Also keep in mind that the system components of MIUI cannot be transferred, they must remain on the built-in drive for the phone to work properly.
☑️ Pre-transfer check
Using a Developer Mode for Forced Transfer
If the standard method is not working or the transfer button is inactive, you can try activating the hidden Android feature, which allows the system to perceive the external card as an extension of internal memory by default. To access these settings, you will need to enable the developer mode on your Xiaomi Redmi. 7A.
Go to Settings. → About the phone and find the line "Version" MIUI". Press it quickly. 7-10 Once in a row, until you get a notification that you have become a developer, and then in the main settings menu will appear a new section "Additional" or immediately "For developers", where we are the settings we need.
In the developer menu, scroll down to the memory section. Find "Preferred installation location" or "Save new applications to an external drive." Activate this switch. Now, when you install new programs, the system will default to offer a memory card if the application supports this.
Risks of using the developer mode
It is important to understand that even with this feature enabled, many modern applications, especially banking clients and instant messengers, can ignore the setting and require installation strictly in internal memory.
Advanced Method: Using ADB Commands
The most effective way to circumvent the restrictions MIUI, It is the use of the Android debugging bridge (ADB). This method requires a computer with Windows, macOS or Linux, and USB-With the help of a cable. ADB We can give the system a command to count. SD-The card is part of the internal memory, which is technically called adoptable storage.
To get started, you need to download and install the Platform Tools package from the official Android developer site to your computer. Also, on the phone in developer mode (as discussed above), you need to turn on the item "Debugging by USB." When connecting your smartphone to your PC, confirm the debugging permission in the pop-up window on the phone screen.
adb shell pm set-install-location 2Type this command in the computer's command line by pre-connecting the phone. 2 indicates the priority of the external card. If you want to return everything back, use 0 (automatically) or 1 (internal memory only), this method works at the system level and is often more effective than standard settings.
⚠️ Attention: When in use ADB Be very careful, because if you enter the settings incorrectly, you can cyclically reboot the device.
After completing the command, it is recommended to restart the smartphone. Check if the new application has been installed on the memory card. If the result is not achieved the first time, try to remove the application and install it again while the phone is connected to the computer with an active command.

Transfer of multimedia and application cache
Even if the apps themselves can't be moved in their entirety, you can free up a lot of space by moving their cache and media files. Many heavy programs, like Telegram, WhatsApp, or Viber, store gigabytes of photos and videos in their folder. SD-The card can free up several gigabytes of internal memory Redmi 7A.
Use a built-in file manager or download an advanced analogue, such as Total Commander or FX File Explorer. Find an Android/media folder or a messenger root folder (such as Telegram). Select the images, video or cache folders and move them to an external drive.
💡
In the Telegram and WhatsApp settings, you can manually specify a path to save downloaded files. Go to the chat settings and select a folder on the SD-Map so that new media files are immediately saved there.
Some applications may stop seeing files after transferring the folders, so within the application, set a new path to the media files in the settings, for example, the gallery may need to rescan the memory or specify a folder to display.
- 📂 Open the file manager and find a folder with a heavy app.
- ✂️ Cut folders with media files (photos, videos, documents).
- 📥 Put them in the root. SD-maps or in a specially created folder.
- ⚙️ Check the application and, if necessary, specify a new path in its settings.
Possible problems and solutions
In the process of memory optimization, users of Xiaomi Redmi 7A may face a number of typical problems, most often due to the fact that the write speed to the memory card is lower than the application requires, as a result, the program can run longer than usual or fly out immediately after opening, in which case, try replacing the card with a faster one.
Another common problem is that app widgets disappear after porting, so if the widget is missing from your desktop, try removing it and adding it back from the widget menu, sometimes by completely restarting the device to reassemble the paths to the files.
⚠️ Warning: If your phone is running much slower after transferring apps, return the most important programs (navigator, messengers) back to internal memory.
Also worth mentioning is the issue with updates.The Google Play Store may refuse to update apps moved to SD-The card is a "Not enough space" error, even if the card is free, in which case temporarily return the application to internal memory, update it, and then move it again.
💡
The optimal strategy is to keep only the system and critical applications on internal memory, and store games and multimedia content on the map.
