Transfer applications to memory card on Xiaomi Redmi 5A: the full guide

Owners of the popular budget smartphone Xiaomi Redmi 5A often face an acute shortage of built-in storage, especially in versions with 16 GB of memory. Modern applications are growing in size, absorbing free space, which leads to slowdown and inability to install new programs. The solution to this problem is the use of an external microSD card, but standard methods of transferring files do not always work effectively for system applications.

Unlike more expensive models, where memory management functions are extended, the Redmi 5A shell-operated MIUI The transfer process has its own technical features and limitations. Standard Android system allows you to move only a part of the data, while the full transfer of the executable application file (APK) It's only possible through Adoptable Storage, which is the default hidden by the manufacturer. Understanding these nuances will help you manage your space efficiently without losing productivity.

In this article, we will discuss in detail all available ways to optimize memory, from standard system tools to advanced methods using debugging via USB. You will learn how to turn a regular flash drive into a full-fledged continuation of internal memory, what risks this carries and how to avoid typical errors when working with the Android file system.

Features of the file system and memory Redmi 5A

Xiaomi Redmi 5A is based on the Qualcomm Snapdragon 425 processor, whose architecture provides for separation of memory into the system partition and user storage. Android operating system (in versions 7.0 Nougat and 8.1 Oreo, current for this model) by default considers the memory card as an external removable storage designed for multimedia. This means that without special settings, you can save only photos, videos and documents, but not the applications themselves.

A key issue is Android’s security mechanism, which isolates applications from external media to protect data. When you install a program from Google Play Market, it defaults to the /data partition. Trying to migrate it with standard means often results in only cache and small files being left on the USB drive, while the program’s body remains inside, continuing to occupy precious gigabytes.

⚠️ Warning: Forced movement of system applications without proper preparation can lead to unstable operation of the interface MIUI and the occurrence of cyclic reboots of the device.

To manage resources effectively, you need to understand the difference between Portable Storage and Adoptable Storage, the first mode being standard, the second mode allowing the system to consider the card as part of an internal drive, encrypting it and making it unreadable on other devices without unlocking it.

Standard method of transfer through MIUI settings

The safest, though limited, way is to use the built-in MIUI shell features. This method does not require a computer connection or activation of hidden modes, but allows you to transfer only those applications whose developers have explicitly allowed this possibility.

Then you go to the settings menu where the application management section is located, and here you will see a list of all installed programs and the amount of work they take up, and the system will automatically filter out those that can theoretically be moved, but in practice, the number of programs on the Redmi 5A can be minimal.

The algorithm for the normal transfer is as follows:

• 📱 Open Settings and go to the Application section.
• 📂 Select All Apps to view the full list.
• 💾 Click on the desired application and find the Memory button.
• 🔄 If the button is changed or moved to SD Active, press it and confirm the action.

It's important to note that even after a successful transfer, some of the data will still remain in internal memory, which is normal behavior of the system, which ensures the speed of frequently used programs. If the transfer button is absent or inactive (gray), then the application developer has banned its placement on an external medium, and this cannot be circumvented by standard means.

💡

Use UHS-I speed memory cards (U1 or U3) to minimize delays when launching applications from external media. Cheap cards can severely slow down your smartphone.

Activate Adoptable Storage Mode via ADB

To fully merge the memory card with internal storage on Xiaomi Redmi 5A requires activation of the hidden Adoptable Storage function. Since this option is not in the settings menu, you need to use the Android debugging toolkit (ADB) from the computer, this method allows you to format the card so that the system will perceive it as an integral part of the internal disk.

Before starting the procedure, make sure that the smartphone is debugging via USB. To do this, go to Settings → About Phone and quickly click on the MIUI build number seven times until the message appears to turn on the developer mode. Then activate the Debugging over USB in the advanced settings.

The activation process requires the following steps:

• 💻 Connect your smartphone to your PC and install drivers ADB.
• ⌨️ In the command line, enter the adb shell to enter the device shell.
• 🔍 Find the card ID by the sm list-disks command.
• ⚡ Run formatting with sm partition disk:XXX private where XXX — ID your card.

Once the command is executed, the card will be formatted and encrypted, the system will restart the memory management process, and a single memory pool will appear in the storage, and now all new applications will be installed on the card by default, if the internal memory is full, and the old ones can be moved completely.

⚠️ Note: After formatting in Adoptable Storage mode, the memory card will cease to be read on other devices (PCs, cameras) without first resetting the smartphone on which it was activated.

Use of third-party utility and file managers

If you don't want to mess with the command line, you can use specialized applications from Google Play that automate the transfer process. One of the most popular tools is Apps2SD or Link2SD. These programs create links to application files, actually transferring them to the map, but leaving shortcuts in the system to work correctly.

Root rights are often required to operate such utilities, which can be obtained on Redmi 5A through unlocking the bootloader and installing Magisk or SuperSU. However, it is worth considering that obtaining superuser rights voids the warranty and can disrupt the operation of banking applications using SafetyNet protection.

File managers like ES Explorer or Total Commander also allow you to manually move folders with data (like the Obb and Data games cache), which frees up space but does not carry the application itself.

/Android/obb/com.example.game


/Android/data/com.example.game

Using third-party software gives flexibility, but requires care. An error in the path to the file can cause the application to stop running or lose the stored progress. Always back up important data before mass moving files.

Comparison of data storage methods on Redmi 5A

The choice of memory management method depends on your goals and technical background, and below is a table comparing the basic approaches to saving applications and data on the Xiaomi Redmi 5A.

As you can see from the table, Adoptable Storage is the middle ground for advanced users who don't want to get into the system files with.root rights. It provides the most native integration of the card, but the speed in this case depends on the speed class of your microSD card.

If you use your smartphone for simple tasks and don’t install heavy games, standard media transfer to a map may be enough. By freeing up internal memory from photos and videos, you automatically create space to install new applications that can’t physically live on a flash drive without deep modifications to the system.

Possible problems and solutions

In the process of memory optimization, Redmi 5A users may encounter a number of common problems, most commonly the “Not enough space” error even after the transfer, which is associated with fragmentation of the file system or the presence of hidden system files that cannot be moved.

Another common situation is slowing down, which happens when you use a cheap memory card with a low read/write speed, applications running from a slow card load longer, and animations can slow down, in which case it is recommended to return to storing applications in internal memory, leaving only media files on the map.

⚠️ Warning: If your smartphone starts to freeze frequently after transferring apps, try removing the memory card. If the problem disappears, the memory card is faulty or too slow for the applications to work.

There may also be conflicts when updating applications. Google Play may try to update the program to internal memory, detecting file residues there, which leads to an installation error.

💡

The quality of the memory card directly affects the stability of the smartphone when using it for applications. Do not skimp on the drive by choosing brands SanDisk, Samsung or Kingston.

Recommendations for choosing a memory card

For Xiaomi Redmi 5A, which doesn’t have top-end performance, choosing the right drive is critical. Support for cards up to 128GB (officially) or 256GB (unofficially, but it works) allows for a significant expansion of the device’s capabilities.

The best choice will be Class 10 cards with the marking UHS-I. Higher standards (UHS-II, UHS-III) smartphone may not support due to the limitations of the controller, and cards below Class 10 will lead to noticeable lags. The volume of 32-64 GB is the “golden mean” in price and performance for this model.

When buying, pay attention to the speed of writing, because it affects the speed of saving photos and installing applications. Reading is usually acceptable for all cards, but writing to cheap models can be extremely low. You can check the real speed with test applications like A1 SD Bench immediately after installation.
