Transferring applications to a memory card on Redmi 7A: Complete guide

The smartphone Redmi 7A remains a popular budget device, but its built-in memory often becomes a bottleneck for modern users. Installing several heavy apps or games instantly fills up the available space, causing the system to run slower and blocking the installation of new updates. Device owners are often looking for ways to expand the functionality of the gadget without buying a new phone.

Fortunately, the architecture Android allows the use of external drives not only for storing photos, but also for storing part of the system data. However, in the shell MIUI ot Xiaomi this process is hidden from the average user and requires completed actions. It is not always possible to move the cache or application body using standard methods, which causes confusion.

In this material we will analyze in detail all the available methods, from native system settings to advanced methods using USB debugging. You will learn what risks exist when formatting a card as internal storage and how to properly prepare the media for stable operation of your Redmi 7A.

Preparing a memory card and smartphone for work

Before starting any manipulations with the file system, you need to make sure that the one you are using is serviceable and compatible SD cards. Budget smartphone models, such as Redmi 7A, may be sensitive to write speed and drive class. Using old or damaged cards may result in data loss or cyclical rebooting of the device.

It is recommended to use memory cards of class Class 10 or higher, standard UHS-I. This will provide sufficient read and write speeds needed to run modern applications. If the card was previously used in another device, it is better to first format it on the computer in the file system FAT32 or exFAT.

⚠️ Attention: All actions to format the memory card lead to complete deletion of data. Be sure to save important photos and documents to your computer or cloud storage before starting the procedure.

Insert the card into the appropriate tray slot Redmi 7A and wait until the system notifies you about connecting a new drive. If the notification does not appear automatically, go to the settings section to make sure that the phone sees the external media. Only after successful detection can you proceed to further steps.

Standard method through storage settings

The first and safest method is to use the built-in functionality shell MIUI. In the latest firmware versions, developers often hide the direct portability option, but basic memory management tools remain available. This method does not require connecting to a computer and using third-party software.

Open the menu Settings and find the item Storage (or “Memory”). This section displays detailed statistics on the use of internal space and external map. The system itself will offer to clear space or transfer certain types of files if it deems it necessary.

Click on the name of your SD card in the list of storage devices. In the menu that opens, select the option Use as internal storageif available. In some regions and versions MIUI this function is blocked, and then you will have to use the alternative methods described below.

If standard transfer is not available, the system may offer to move only media files. In this case, in the memory management menu, select the applications that take up the most space and check for the presence of the button Change or Move to SD. For system applications, this option is most often inactive.

Using developer mode to force a transfer

There is a hidden setting in Androidthat forcibly allows you to install applications on an external drive, even if the developer did not provide for it. To activate this feature, you need to access the developer menu on your Redmi 7A.

Go to Settings → About phone and find the line MIUI version. Click on it quickly 7-10 times in a row until a message appears indicating that you have become a developer. After this, a new section will appear in the main settings menu Advanced or immediately the item For developers.

Inside the developer menu, scroll down the list to the section related to applications. Find the switch named Allow saving to external drives (or “Force allow apps on external”). Activate this toggle switch.

⚠️ Attention: Enabling this function may lead to unstable operation of some applications, since they are not optimized to work with a slow SD card instead of fast internal memory.

After enabling the option, restart your smartphone. Now, when installing new applications, the system will prompt you to select an installation location, and a transfer button may appear in the settings of already installed apps. However, it is worth remembering that not all APK files support this function at the code level.

Advanced method: ADB command and App2SD section

If software methods do not produce results, you can use the tool ADB (Android Debug Bridge). This is a powerful tool from Googlethat allows you to control the system from your computer via the command line. The method requires a PC and a USB cable.

First you need to install drivers for Redmi 7A and platform Platform-tools on your computer. Connect your phone in USB debugging mode (the item is included in the developer menu mentioned above). The computer should detect the device.

Open the command line in the folder with ADB and enter the following command to check the connection:

adb devices

If a device with status deviceappears in the list, you can enter a command to force the transfer of a specific application. You will need to know the exact package name (eg com.example.app). The command looks like this:

adb shell pm set-install-location 2

Value 2 means the priority of the external card, 0 is automatic selection by the system, and 1 —internal memory only. After running the command, try reinstalling the desired application. This method works at the system level and is applicable to all installed packages.

What to do if ADB does not see the phone?

Make sure that a window asking for debugging permission appears on the smartphone screen, and click “OK”. Also try replacing the USB cable with an original or better one, since cheap cables often only support charging.

Method compatibility table for different versions of MIUI

The effectiveness of the methods described above directly depends on the version of the installed firmware. Xiaomi regularly changes security and memory management policies in updates MIUI. Below is a table to help you navigate the available options.

MIUI version	Standard transfer	Developer mode	ADB commands	Stability
MIUI 10 (Android 8/9)	Partially	Working	Working	High
MIUI 11 (Android 9/10)	Limited	Works	Works	Average
MIUI 12 / 12.5	No	Often blocked	Requires rights	Low
MIUI 13 and later	No	Does not work	Difficult	Unstable

As can be seen from the table, on new firmware versions the transfer capabilities are significantly reduced. This is due to the introduction of technology Sandbox and increased requirements for the speed of applications that may not function correctly on a memory card.

If you are using a global version of the firmware, the restrictions may differ from the Chinese version. In some cases, flashing to an earlier version helps. MIUI, but this is a complex process that requires unlocking the bootloader.

Optimization and elimination after transfer

After applications have been moved to the memory card, it is important to monitor the state of the system. Data read speed is SD cards lower than the built-in memory chip, so apps may take longer to launch. This is normal, but should not lead to freezes.

Periodically check the integrity of the files on the card. An error checking function is available in the storage settings. If you notice that applications often crash or do not save progress, the card sector may be damaged or the recording speed has dropped.

⚠️ Attention: Settings interfaces and menu item names may vary depending on the MIUI version and the regional setting of the device. If you do not find the described options, check the latest information in the official documentation for your model.

To extend the life of the memory card, it is recommended to minimize the number of write operations. Do not install applications on an external drive that constantly update data in the background, such as instant messengers or navigators. It is better to leave them in internal memory.

Possible problems and their solutions

During operation, situations may arise when moved applications stop working or disappear from the list. This is often due to the fact that the system Android did not have time to mount the data partition upon boot. Try removing and reinserting the card.

Another common problem is the “Application not installed” error when you try to update a app located on external media. In this case, you need to temporarily return the application to internal memory, update it, and move it again.

If the memory card is determined to be damaged, do not rush to format it immediately. Try connecting it to your computer via a card reader and checking for logical errors using standard means Windows or macOS. Sometimes full formatting helps exFAT.

Why does the application run slower after transfer?

The random read and write speed of most memory cards is much lower than that of the built-in flash memory of a smartphone. Heavy applications that require fast loading of resources may experience delays. For such apps, using an SD card is not recommended.

Is it possible to transfer WhatsApp and Telegram to the card?

You can transfer the application body itself, but media files (photos, videos) of these messengers are saved to internal memory by default. In the settings of the applications themselves, you can specify the path to save media to the SD card, which will free up a lot of space.

What happens if you remove the card with installed applications?

Applications will stop launching, and their shortcuts may disappear from the desktop or become inactive. The system will assume that the apps have been removed. After returning the card to its place, functionality will be restored, but a reboot may be required.

Does the transfer affect the Redmi 7A warranty?

The use of memory cards and standard developer settings does not affect the warranty. However, if you use methods that require Rooting or unlocking the bootloader, the warranty may be voided.

How to return all applications back to the internal memory?

To do this, you need to go to the settings of each application and click the "Move" button (if it is active) or use the ADB command: adb shell pm set-install-location 0, after Why reinstall applications.
