Owners of budget and mid-budget models Xiaomi, Redmi and POCO often face critical shortages of internal memory. Current applications take up gigabytes, and built-in storage of 64 or 128 GB becomes insufficient for comfortable work. Users are looking for ways to free up precious space so that the phone does not slow down due to a crowded system partition.
The most affordable solution is to use SD-However, since Android 6.0 and up, the standard portability mechanism has been changed by the developers, and now requires a deeper dive into the settings or the use of hidden developer features. In this article, we will discuss all current methods of memory expansion.
We'll look at the standard capabilities of MIUI and HyperOS, and more advanced ways of forcing data transfer, and you'll learn what risks are involved with the file system and how to minimize the likelihood of losing important information. Prepare for the process to take attention, but the result is worth it.
Analysis of the current situation: why the system limits the transfer
Many users mistakenly believe that the app portability feature is completely removed; in fact, Google and smartphone makers are pursuing policies to improve stability, and internal memory (eMMC or UFS) is much faster than even the fastest microSD cards.
If you move a heavy application to a slow drive, it will take longer to load, and you may get friezes. Android defaults to blocking the transfer of system components and mission-critical services to prevent device failures, and this is done to protect the user from inexperience.
⚠️ Warning: Before any memory manipulation, be sure to back up important data. Working with storage partitions carries the risk of accidental loss of information if the process is interrupted or performed incorrectly.
However, for games, large-cache messengers, and media applications, portability is possible, freeing up space for system updates and new photos, and understanding memory architecture will help you make informed decisions about what to move to external media.
💡
System restrictions are not introduced to complicate life, but to ensure a stable speed of your smartphone in the long run.
Preparation of SD-card and storage configuration
The first step is to properly prepare the external drive. Not every memory card is suitable for installing applications. You will need a medium with a speed class at least Class 10 or the UHS-I standard. Using slow cards will lead to a severe decrease in the performance of the phone.
Put the card into the slot and wait for the system to notify. Modern MIUI shells often suggest using the card as a portable storage. For our purposes, this may not be enough, but this is a baseline. Go to Settings → About Phone → Storage to check status.
☑️ Checking the readiness of the memory card
If the card has been used on another device before, it's better to format it. This will delete all the data, but create a clean file system without errors. Go to Settings → Advanced Settings → Storage, select your card and click "Clean". After that, you can start more complex settings.
Method 1: Transfer through application settings
The safest and easiest way to do this is without superuser rights. It doesn't work for all programs, but for many games and third-party utilities, the option is active. Go to Settings → Apps → All apps.
Find a program you want, like a heavy game or a photo editor, and click on it to open the information page. If you can move it, you'll see a Change or Move to the page. SD-If the button is grey or missing, the developer has banned the transfer.
In some versions of the firmware, the path may be different. Try to find the Memory section inside the menu of a particular application. There may be a "Use external storage" switch. This is especially true for messengers like Telegram or Viber, where you can manually specify the path to save media files.
💡
For instant messengers, it is often more effective to change the way files are saved in the application settings themselves than to try to migrate the entire application setting. APK-program.
Once confirmed, the system will start moving files, which can take from a few seconds to a few minutes depending on the amount of data, do not remove the card during the process, and when completed, the application will be marked with a memory card icon in the list of installed programs.
Method 2: Use of Developer Mode (Forced MS)
If the standard method didn't work, you can try activating the hidden Force allow apps on external, which will make the system think that the external card is part of the internal memory, and you need to activate the developer menu.
Go to Settings → About Phone and quickly press 7 times on MIUI Version (or OS Version). You will see a notification saying "You became a developer." Then go back to Advanced Settings → For Developers.
Find Force allow apps on external. Activate the switch. Reboot the smartphone. Only after the reboot will the changes take effect, and the app menu may be able to move.
| Parameter | Standard regimen | Developer mode | Adoptable mode |
|---|---|---|---|
| Availability | Depends on the app. | Depends on the app. | Requires ADB/Root |
| Security | Tall. | Medium | Low. |
| Impact on speed | Minimum | Average. | High (risk) |
| Difficulty | Low. | Medium | Tall. |
It's important to understand that this method doesn't guarantee 100% success, some system applications will still be unavailable for portability, and after updating the firmware, the developer's settings may reset and the procedure will have to be repeated.
Method 3: Advanced Methods with ADB and Adoptable Storage
For experienced users, there is a way to transform SD-This is a method called Adoptable Storage, which requires you to connect your smartphone to your computer and use debugging. USB.
You'll need to install ADB drivers on your PC and enable debugging in the developer menu. Connect your phone with a cable and type in a command to check the connection: adb devices. If the device is determined, you can go to markup.
adb shell sm list-disks
adb shell sm partition disk:179,64 mixed 50In the command above, disk:179.64 is your card ID (you need to know it through the first command), and mixed 50 means that 50% of the card will be given to applications, and 50% will remain under files.
⚠️ Attention! Once this command is executed, the card will be formatted and encrypted, and it will no longer be readable on other devices (cameras, PCs) without special unlocking on this particular smartphone.
This method allows the system to automatically install new applications on the map if they are allowed to be transferred, but if the memory card fails or is lost, all the applications installed in this way will stop working and they will have to be reinstalled again.
Alternative solutions: working with cache and garbage
Often the problem is not the number of applications, but the bloated cache. Social networks and browsers can take up gigabytes of temporary files. Regular cleaning helps to avoid the need to transfer programs.
Use Xiaomi's built-in Security app, which can find residual files and clear cache, and you can use third-party utilities, but with caution not to delete the necessary logs or save games.
What folders can be manually deleted?
Another option is to use cloud storage, transfer photos and videos to Google Photos or Yandex.Disk, enabling the "Free Space" function, which will delete local copies of files, leaving them available online, which will significantly relieve internal memory without losing access to media.
Possible problems and ways to solve them
After transferring applications, users may experience unstable work, applications may fly out, take a long time to load or stop receiving notifications, often due to the low speed class of the memory card or its physical wear and tear.
If you notice that your phone is running slower, try to return the apps back to internal memory. Go to the storage settings and select Move to internal memory. Check the health of the card using speed tests, for example, through the A1 SD Bench application.
You can also have a situation where, after you update the system, all the port settings are reset, in which case you have to repeat the procedure. Always watch for free space on the map - if it is overflowing, the applications may stop running.
💡
The speed of the memory card directly affects the performance of ported applications, and cheap cards without UHS-I marking can become a bottleneck for the entire system.
Outcomes and operational recommendations
Moving applications to a memory card in Xiaomi is a trade-off between storage capacity and speed. For low-cost devices with little internal storage, it is often the only solution to install the necessary programs.
Use quality memory cards from proven brands such as Samsung, SanDisk or Kingston. Avoid buying media in markets without packaging, as the risk of running into a fake with understated volume is very high.
Check the status of the card regularly and back up important data. Remember that the external drive is less reliable than the internal memory of the phone. With the right approach, you can effectively manage the space of your smartphone.
