How to add memory to Xiaomi Redmi 7A: the full guide

Owners of the popular budget smartphone Xiaomi Redmi 7A often face a lack of built-in storage, which leads to slowdown of the device and the inability to install new applications. Limited internal memory of 16 or 32 GB quickly filled with system files, updates and user content.

There are several proven methods to address this problem, ranging from simple garbage cleaning actions to more complex file system manipulations. Storage optimization requires a holistic approach, as simply removing a couple of photos is not enough. We'll look at all the available methods, including using memory cards and specialized software, to make your phone work quickly again.

Before we start taking drastic measures, we need to understand the structure of the disk filling and identify the main users of space. The MIUI operating system installed on board has its own data storage features that can be used to your advantage. Proper file management will significantly extend the life of the device without buying a new smartphone.

Storage occupancy analysis and search for hidden files

The first step to freeing up space is to make a detailed diagnosis of what exactly takes up precious gigabytes. Standard Android tools don’t always show the full picture by hiding bulky folders of garbage from messengers and browsers. System analyzer allows you to see the real disk space allocator and understand where free megabytes go.

It often turns out that the lion's share of the space is occupied by social media cache, which can grow to several gigabytes. Duplicate files and remnants of remote applications also take up a significant amount of space. You need to manually check the download folders, where APK installation files and temporary documents often accumulate.

For more in-depth analysis, you can use third-party utilities that visualize data in the form of diagrams. DiskUsage or Files by Google is great at finding forgotten videos and heavy archives. Once large files are identified, they can either be deleted or moved to an external medium.

It is important to regularly review the Android/data folder, where game and application data are stored. Clearing the cache through the settings of a particular application is often more effective than using the Cleanup function in the standard menu, which allows you to delete only temporary files without affecting important logins and settings.

Using a microSD card to expand space

The most obvious and reliable way to add memory to the Xiaomi Redmi 7A is to install a microSD card. This smartphone features a separate slot that supports cards up to 256 GB and even higher, which dramatically changes the device’s capabilities.

Once installed, you need to set it up correctly through the Settings → Storage menu.You can use the card as a portable storage or, in some cases, as part of internal memory, although the latter method on modern versions of MIUI may be limited or absent. It is recommended to format the card in the exFAT file system to support files weighing more than 4 GB.

• 📀 Choose a high-quality memory card of the speed class U1 or U3 from a proven manufacturer.
• 📂 Set up automatic photo and video saving from the camera immediately on SD-map.
• 🎵 Move music and uploaded movies to folders on external media.
• 📱 Use the card to carry heavy but rarely used applications.

⚠️ Note: Not all applications support porting to a memory card. System programs and some banks may not work correctly or even start when moving to an external drive.

When using a memory card, it is important to back up data regularly, since external drives are less reliable than built-in flash memory. The speed of reading a card directly affects the speed of applications running from it, so you should not save on the speed class. For the Redmi 7A, 64 or 128 GB cards will be the best choice.

Cleaning up system debris and app cache

Regular digital garbage cleaning is the basic hygiene for any Android smartphone. As it works, the operating system and apps create a lot of temporary files that accumulate and take up space over time. Xiaomi’s standard “Security” app has a built-in cleaner that efficiently removes obvious debris.

Deep cleaning, however, will require manual intervention or the use of advanced tools.The cache of Google Play and Google Services Framework is often inflated to unthinkable sizes, especially if you update apps or games frequently.The data cleanup of these services is secure and will not lead to loss of personal information, but may require re-entry into your account.

Special attention should be paid to messengers like Telegram and WhatsApp, which by default save all received media files. In the settings of these applications, you can limit auto-save or set up auto-delete old files. Document folders in instant messengers also often contain old presentations and archives that are no longer needed.

Use the Deep Clean feature in the standard application, but carefully check the file list before deleting. Automatic algorithms may mistakenly suggest that important files be deleted if they are not recognized by the system. It is always better to double-check than to lose the desired document or photo.

Removing System Applications and Optimizing MIUI

The MIUI shell is known for its abundance of pre-installed software that users don't always need. Removing or disabling such applications not only frees up space, but also reduces the load on RAM and CPU. The system partition takes up a fixed volume, but the user partition can be greatly facilitated.

Removing system applications that are not removed in the standard way will require root rights or the use of ADB (Android Debug Bridge). Through ADB, you can safely "freeze" or remove unnecessary components such as advertising services, unnecessary browsers or games from the manufacturer. ADB commands are executed from the computer and require the inclusion of debugging over USB in the menu for developers.

adb shell pm uninstall -k --user 0 com.miui.videoplayer

This command, for example, will remove Xiaomi’s standard video player if you prefer third-party counterparts.Be careful: removing critical system components can lead to unstable device operation or cyclical reboot.

💡

Before you uninstall system applications via ADB, write down the names of the packages you plan to remove, making it easy to restore them if necessary by the install command.

Application transfer and work with virtual memory

The issue of porting applications to a memory card remains relevant for owners of devices with a small amount of internal storage. In older versions of Android, there was an Adoptable Storage feature that allowed you to combine internal and external memory into a single space. On Redmi 7A with updated versions of MIUI, this feature is often hidden or removed by developers.

However, some apps allow you to choose the installation path in your settings. → Annexes → Manage applications, select the desired program and see if the button "Move to" is active. SD-If the button is grey or missing, the app developer has banned the transfer. System restrictions are almost impossible to get around without root rights.

There are enthusiastic apps that create a virtual partition on a memory card and try to trick the system into thinking it is internal memory. However, such methods on modern versions of Android work unstable and can lead to errors in the operation of applications. Virtual memory through swap files (requires root) can help with a lack of RAM, but will not solve the problem of lack of storage space for files.

⚠️ Note: Using third-party programs to “unify” memory can lead to loss of data on the map and unstable system operation.

The safest way is to train yourself to install heavy games and applications that do not require high download speeds on a memory card if such an option is available, and keep system ones inside. Default installation optimization is also available in some file managers, allowing you to immediately download APK to an external drive.

💡

The most effective way to combat memory deficiency is to combine the use of high-quality memory. SD-cards for media and regular cleaning of messenger cache.

Cloud storage as an alternative to local memory

In the era of cloud technology, storing all files on a device is becoming less relevant. Services like Google Photos, Yandex.Disk or MI Cloud allow you to store huge amounts of data on the Internet, freeing up space on your smartphone. Cloud synchronization provides access to files from any device and protects against data loss when your phone breaks.

Configure automatic upload of photos and videos to the cloud, then delete local copies. The "Free Space" feature in the Google Photos app automatically removes from the device images that are already uploaded to the cloud, which allows you to instantly free up several gigabytes of space, leaving only thumbnails in the gallery.

• ☁️ Set up autoload photos in Google Photos or Mi Cloud.
• 🗑️ Use the "Free Place" function after synchronization.
• 📄 Move your documents and archives to cloud storage.
• 🎵 Use streaming services instead of storing music in memory.

Using the cloud requires a stable Internet connection, which can be a downside to poor network coverage. However, for Redmi 7A, which is often used as a second device or phone for older people, this approach makes it as easy as possible to maintain and avoid problems with memory overflow. Cloud storage plans are now quite affordable and offer large volumes for a nominal fee.
