Transfer applications to the memory card Xiaomi Redmi 7A

Owners of budget but reliable smartphones such as the Xiaomi Redmi 7A often face a shortage of internal storage. Standard 16 or 32 gigabytes in modern realities are catastrophically small, especially given the appetite of messengers and social networks. The MIUI system installed on the device takes up a significant part of the space, leaving the user with minimal space for personal needs. When internal memory is full, the phone begins to work slower, and installing new programs becomes impossible.

Fortunately, the Redmi 7A features a microSD card slot that theoretically expands the available space. However, standard tools do not always allow you to simply click the Move to SD button. MIUI has its own features with the file system that limit the direct transfer of executable files. In this article, we will discuss all available methods, including standard settings and more advanced methods through ADB.

It's important to understand that not all applications support portability, even if the system allows it. Critical system components and some banking services must remain in internal storage for stability and security. However, moving games, media editors and social media cache can free up gigabytes of precious space. Let's look at how to properly prepare the device and what steps need to be taken to optimize memory.

Preparation of a memory card and smartphone

Before you start manipulating system files, you need to make sure that the drive used is healthy and compatible. Xiaomi Redmi 7A supports memory cards up to 256 GB, but it is better to choose proven brands such as SanDisk or Kingston. Write and read speed directly affects the speed of applications if they are partially placed on an external medium. Using a cheap low-speed card can lead to the fact that programs will run longer than usual.

The first step is to format the map into a file system that Android understands, usually FAT32 or exFAT. If you already have data on the map, you better copy it to your computer, because in the process of formatting all the information will be destroyed. Put the card into a slot, wait for the system to notify and go to the storage settings. Here you need to choose whether to use the card as a portable medium if you plan to retrieve it often, or as an internal storage device that will allow the system to integrate it into the total memory.

⚠️ Note: When formatting a card as an internal storage, it is encrypted and linked to a particular device, and you can't read it on another phone or computer without re-formatting and losing data.

Once formatted successfully, the system will suggest moving some of the content. You can agree to move photos and videos to make room. In order to move the apps themselves, we'll need to turn on the developer mode. It's a hidden menu that gives you access to advanced Android settings. Without activating this mode, many commands will be unavailable.

💡

Use a UHS-I or higher speed memory card to ensure that applications ported to an external medium do not slow down when starting.

Activation of the developer mode and debugging

To manage the installation of applications through a computer or specialized utilities, you need to activate hidden system functions. This process is simple, but requires care when entering data. First, open the Settings menu and go to the About Phone section. Here we are interested in the MIUI version. You need to quickly click on this item seven times in a row. After a few clicks, a counter will appear that tells you how many times you have to press before activating the mode.

When the developer mode is activated, go back to the main settings menu and find the option "Additional Settings." Inside you'll see a new section, "Developers." That's where the key switches for engineers and advanced users are. We're interested in the USB debugging option. It needs to be enabled to allow the computer to connect to the smartphone. Without this step, the computer will not be able to send commands to the device.

Also on this menu, you should pay attention to the item Do not turn off the screen when you connect charging, which can be convenient for long-term operations. After you turn on debugging on the first connection to the PC, you will see a request for debugging permission from this computer. Be sure to check the box Always allow and confirm the action. This will create a digital security key that prevents unauthorized access to your Redmi 7A data.

Use of Adoptable Storage

One of the most effective yet hidden features of Android is the ability to turn a memory card into an extension of internal memory. In Xiaomi's standard menu, this option is often hidden, but it can be activated. SD-It's like a system partition, and it allows you to put applications directly on the map or to transfer them to the map in their entirety, including data and cache.

This method may require a computer connection and an ADB command line. It's not as scary as it sounds. Once you plug in the phone and enable debugging, you have to type a command into the command line on your PC to get a list of drives. Usually, the memory card is displayed as 179.64 or similar identifier, and then you run a formatting command that creates the necessary partitions.

adb shell sm partition disk:179,64 private 100

This command will completely re-mark the card, and after the reboot, the system will assume that the total amount of internal memory has increased, and now when you install new applications, Play Market will automatically use the freed space, but it is worth remembering that the memory card's speed is lower than the speed of the built-in flash module, so heavy games can load a little longer.

⚠️ Note: If you remove the memory card after such formatting, all applications transferred to it will cease to work, and their icons will disappear from the desktop before re-inserting the card.

Application portability by standard MIUI tools

Even without the complex manipulation of ADB, MIUI has some basic memory management tools that don't always allow you to move the body of an application, but they allow you to move the data. Go to Settings, select Apps, and then All Apps. In the list, find the program that takes up the most space, like Viber or Telegram.

In the menu of a particular application, find the Memory button. If the memory card is formatted correctly, the Change button will become active. SD-Moving cache and media files of a messenger can free up hundreds of megabytes, which is especially true for those who actively share photos and voice messages.

It's worth noting that for some Google system applications and services, this option will not be available. It's a security limitation that can't be circumvented by standard methods. Don't try to remove or force them to stop, as it can disrupt the entire smartphone. Focus on user-generated content and third-party utilities.

Advanced Methods through ADB AppControl

For those who don't want to mess with the command line manually, there are handy graphical shells. ADB AppControl for Windows allows you to manage applications on Xiaomi Redmi 7A from a computer. It automatically identifies the connected device and shows a list of all installed programs. The program interface has a function of forcing applications to move to an external medium.

The way it works is simple: you select the apps you want in the list, right-click, and you select the navigation option, and it sends the commands to your smartphone, and it's safer than manually typing commands, because the interface shows the status of each application, and you can see which programs you can move and which are system-based, and you don't want to touch them.

Using these gates also allows you to remove embedded debris, or bloatware, which often comes with firmware. Removing unnecessary Xiaomi or Google services that you don't use also frees up space. However, beware: removing critical components can lead to unstable system operation. Always back up before a mass clean.

Typical errors and problem solving

In memory optimization, users often face a number of problems, such as when an application is migrated, it may stop updating to Google Play. In this case, try temporarily returning the application to internal memory, updating it, and then moving it back to the map. It also happens that widgets of the transferred applications disappear from the desktop. They can be returned by adding them again through the widget menu.

Another common problem is the "Application Not Installed" error when you try to download a new program directly to the card, which occurs if the card file system is corrupted or formatted in an incompatible format. Check the card for errors by connecting it to your computer through the card reader. Use the standard Windows Disk Checker utility to correct logical errors.

If your smartphone stopped seeing your memory card after all the manipulations, try rebooting your device. In rare cases, you need to completely reset your settings to the factory settings, but before that, be sure to save all the important contacts and files. Remember, formatting the card as internal storage makes it unreadable on other devices without special reset, an important nuance that is often forgotten.

⚠️ Note: Do not remove the memory card while the applications are running, this can damage the application database and lose progress in games or correspondence.

💡

The most stable result is a combination: transfer of media files to the SD-hand-card and use Adoptable Storage only for heavy games that do not require high download speeds.

Alternative ways to free up space

If partitioning and ADB tinkering seems too complicated, there are simpler but more effective ways to free up space on Redmi 7A. First, clear the download folder. Often APK installation files, old documents and saved browser images are accumulated there. The standard cleaning tool in the MIUI security menu does a good job of handling temporary files.

The second is cloud storage, where services like Google Photos or Yandex.Disk can automatically upload your images to the cloud and delete them from your phone's memory, leaving only thumbnails, and it allows you to store thousands of photos without taking up a megabyte of internal memory, and you only need an Internet connection to view the photos.

The third option is to clean your cache regularly, and you can see in the storage settings which apps take up the most space, often streaming services or navigators, and clearing their cache is safe and doesn't delete your personal data, such as logins or saved routes, and doing this regularly will help keep your phone on top of your phone without having to transfer system files.
