Owners of the Xiaomi Redmi 8 smartphone often face a shortage of internal memory, especially in the base versions with 32 or 64 gigabytes. Built-in storage is quickly filled with system files, updates and cache of popular social networks.
Installing a microSD card is a logical solution to extend the capabilities of the device, but the process of transferring programs has its nuances in the MIUI shell.
In this article, we will discuss in detail the standard methods and hidden features of the system that will help free precious megabytes of internal memory of your gadget.
Features of memory in MIUI
The MIUI shell installed on the Xiaomi Redmi 8 has a strict security policy that by default prohibits installing any programs on an external drive.
This is done in order to ensure the stability of the system and protect user data from loss in the event of the removal of the flash card.
However, there are workarounds that allow you to redirect some data or even entire applications to an external medium without the need to obtain superuser rights.
It is worth noting that not all programs support such migration, as it depends on the code of the developer himself, and not only on the settings of the phone.
⚠️ Before you start any manipulation of the file system, be sure to back up important data, as formatting the memory card will destroy all information on it.
The system divides the memory into a system partition, user space, and virtual partitions for applications to run.
When connecting a memory card, Android suggests using it as a portable storage device or as part of internal memory, but the second option in MIUI is often hidden or unstable.
Preparation of the memory card for work
Successful data transfer requires a high-quality Class 10 or higher memory card, as read and write speeds directly affect the performance of installed programs.
Slow cards can cause interface freezes and long downloads of applications, which will create a false impression of a malfunction of the smartphone.
The first step is to insert the card into the slot located at the end of the case next to the SIM-tray.
Once the media is detected, the system will automatically prompt it to be configured, but we will look at the manual method through the settings menu for full control of the process.
💡
Use memory cards from proven brands (SanDisk, Samsung, Kingston) as cheap counterparts often fail after several overwriting cycles.
Navigation on the menu is as follows: go to Settings → About phone → Storage.
Here you will see a list of connected drives and you can choose the desired map for formatting.
It is important to choose formatting as “Internal Storage” (if available) or simply clear it for use by the system.
The standard method of transfer through settings
The most secure way to move data is available in the standard Xiaomi Redmi 8 interface, although it has limitations.
The system allows you to transfer only those applications whose developers have allowed such a function in the program manifest.
To start the procedure, open the Settings menu → Applications → Application Management.
In the list that opens, select the app you are interested in, such as a heavy game or a navigator.
Click on Memory and if the function is active, you will see the Change or Move to SD-map».
☑️ Verification of portability
If the button is gray or absent, then the transfer of regular funds for this program is impossible.
In this case, you can move only media files or cache if the application supports the choice of the way to save data in its internal settings.
Use of Adoptable Storage
There is a more advanced method known as Adoptable Storage that allows the system to consider the memory card as part of the internal storage.
On the Xiaomi Redmi 8, this feature is often hidden by the manufacturer, but it can be activated via a computer and USB debugging.
To activate, you need to turn on the developer mode by going to Settings → About Phone and quickly pressing 7 times on the “MIUI version” item.
Then, in the advanced settings, activate “Debugging by” USB» And connect the phone to the PC.
⚠️ Note: Once formatted as an internal storage card, it will be encrypted and cannot be read on other devices or computers without being reset.
You will need to enter a command via ADB (Android Debug Bridge) for forced formatting.
The team looks like this:
adb shell sm partition-fuse sdcard:XXX privateWhere XXX is your card ID, which can be recognized by the adb shell sm list-disks command.
Once the command is executed, the phone will restart and the system will begin to redistribute files, which can take a long time.
What to do if the team is not executed?
Alternative Solutions and File Managers
If standard methods have not yielded the desired result, file managers can be used to manually migrate data.
Many applications, such as a gallery, voice recorder or instant messengers, allow you to change the way you save files in your own settings.
For example, in Telegram or WhatsApp, you can use a folder on a memory card to download media files.
This won’t carry the app itself, but it will free up a significant amount of internal memory that photos and videos typically occupy.
There are also specialized utilities, such as App2SD, that monitor the system and tell you which programs can be moved.
They work in conjunction with access rights and can offer cache transfer if root rights are not available.
Regularly cleaning the cache through the built-in Security utility also helps maintain a balance between internal and external memory.
Don’t forget to check the Downloads folder, as unnecessary installation files often accumulate there.
Comparison of methods of memory expansion
For ease of perception of information about different ways of working with memory on Xiaomi Redmi 8, we have prepared a comparative table.
| Method | Difficulty | Efficiency | Risk of data loss |
|---|---|---|---|
| Staff transfer | Low. | Low. | Absent. |
| Adoptable Storage | Tall. | Tall. | High-pitched |
| Transfer of media files | Medium | Medium | Low. |
| Clearing the cache | Low. | Temporary. | Absent. |
As you can see from the table, the most effective, but also the most risky method is to use the card as an internal storage.
The safest way to combine the transfer of media files and regular cleaning of garbage.
💡
The best strategy for the Redmi 8 is to use a memory card to store photos, videos and music, leaving internal memory solely for app installation.
