Xiaomi and Redmi smartphone owners often face a lack of built-in storage, especially on budget models with 32 or 64 gigabytes. Installing games, social networks and instant messengers quickly fills the available space, causing system slowdowns and blocking updates. Transferring data to an external drive becomes the only way to extend the life of the device without buying a new gadget.
However, in modern versions of the MIUI and HyperOS shell, the procedure is not always obvious, because manufacturers hide certain features for the sake of stability. You will not only need to insert the card, but also format it correctly so that the system perceives it as part of internal storage, which will allow you to install heavy applications and cache media directly to an external medium.
In this article, we will explore all the nuances of the process, from choosing the right memory card to hidden settings through the engineering menu, you will learn how to bypass the limitations of the system and safely move application data, while maintaining the performance of the smartphone. Follow the instructions carefully to avoid loss of information.
⚠️ Before you start any memory operations, make sure to back up important photos and documents. Formatting the card will completely delete all the data on it.
Preparation of a memory card and choice of carrier
Success in transferring programs depends on the quality and speed of the drive used. Cheap memory cards with low write speed can become a “narrow neck”, which will make applications run longer and the system hang over. For comfortable work, it is recommended to use cards of the standard Class 10, UHS-I or higher.
The best choice is from proven brands such as SanDisk, Samsung or Kingston. The size of the card should be sufficient: if you plan to carry heavy games, it is better to choose drives from 64 GB and above.
- 🚀 Choose cards with a read speed of at least 90 MB/s for fast downloading of games.
- 💾 Make sure your smartphone supports cards over 32GB (usually up to 256GB or 512GB).
- 🛡️ Buy media only in official stores to avoid fakes with understated characteristics.
After you buy, insert the card into your device's slot. The system should automatically identify the new drive and suggest that it be configured. If the notification does not appear, go to the settings manually. It is important that the card is working and has no logical errors of the file system.
💡
Use the SD Insight utility (available in the Play Market) before buying to check the actual volume and speed of your current memory card, if it is already available.
Formatting the map as an internal storage
The most effective way to free up space is Adoptable Storage, which encrypts the memory card and becomes an integral part of the system, allowing it to install applications on it in the same way as on internal memory, and without this step, many programs simply will not offer the port option.
To activate the function, go to Settings → About Phone → Storage. Find your card in the list and click on it. In the menu that opens, select Format. The system will warn you about loss of data - confirm the action. Then select Use as internal storage.
The formatting process can take a few minutes. Don't remove the card or turn off the phone at this time. Once complete, the system will suggest transferring the already existing data (photos, music) to a new drive, which will also free up valuable space in the internal partition.
| Type of formatting | Description | Ability to transfer applications |
|---|---|---|
| Portable storage | The card works as a flash drive for photos and videos | No (media files only) |
| Internal storage | The map is integrated into the Android system | Yes (full support) |
| No formatting. | Use of the existing file system | Limited (depending on the developer) |
⚠️ Attention! Once you format the card as internal memory, it will only work with that particular smartphone, and you can't insert it into another phone or computer without formatting it again.
Manual transfer of installed applications
Once you have the map set up, you can start migrating programs, and not all applications support porting, because that's the developer's decision, but most games and heavy utilities do, and it's done through the standard application management menu.
Open the Settings. → Annexes → All applications. Select the program you want from the list (like a game or a navigator). Find Memory or Storage. If the map is formatted correctly, the button will appear on the "Change" or "Move to" button. SD-map».
Press the button and wait until the process is over. The travel time depends on the size of the application and the speed of the map. Once completed, the storage menu will indicate that some of the data is on an external drive, which will free up space in the system partition.
☑️ Pre-transfer check
It is worth noting that Xiaomi system applications and some Google services will not be able to move, this is a security limitation of Android, preventing the unstable operation of critical OS components when retrieving the map.
Use of the Engineering Menu for Extended Opportunities
In some cases, the standard menu hides the portability option even if the card is formatted. You can use an engineering menu or special commands to unlock hidden functions. This method requires caution, but allows for the forced permission to transfer for more applications.
To enter debugging mode, activate the MIUI Version in the About Phone menu by pressing it 7-10 times. Then, in the advanced developer settings, look for the "Do not turn off the screen" (to keep the phone awake) and make sure that USB debugging is enabled. However, forced transfer often requires a special command to be entered through a computer or terminal.
adb shell pm setInstallLocation 2This command is introduced through ADB (Android Debug Bridge, from the computer, changes the default priority to an external card. value 2 indicates the system to prefer SD-card, 0 is automatic, 1 is internal memory.
Risks of using ADB teams
Setup of camera and messengers to work with SD
In addition to installing programs, it is important to set up automatic file saving: the camera, voice recorder and instant messengers like WhatsApp and Telegram store data in internal memory by default, and they must be manually switched in the settings of each application.
In the Camera app, click on the menu icon (three bars) and select Settings. Find Save to or Save to and specify the memory card. Now all new photos and videos will be recorded directly to an external medium, bypassing the internal storage.
- 📸 In the Chamber, turn on the option “Priority” SD-maps 4K.
- 💬 On WhatsApp, go to Settings → Data and Storage and Change the Way for Media.
- 🎵 In the music player, point the folder to SD-map as the main library.
For instant messengers, the procedure may be different. In Telegram, the path changes to Settings → Data and memory → Memory Use → Path to cache. In Viber, a similar setting is in the Memory section, which allows you to keep the main memory free for the system to work.
Possible problems and ways to solve them
Despite the correct actions, users may encounter errors: often the system writes “Not enough space” or the transfer button is inactive, this may be due to the file system of the card or the limitations of the Android version.
If the transfer is interrupted, try formatting the card again by choosing the exFAT file system over FAT32 if the smartphone supports it. Also, the problem may lie in damaged sectors of the card - check it on your computer using the SD Formatter utility.
Another common mistake is that widgets and shortcuts of ported applications can disappear from the desktop, in which case add them again through the menu of all applications. If the application stopped running after transfer, return it to internal memory, which means that it is incompatible with working through an external drive.
⚠️ Attention! Do not remove the memory card hot while the phone is on. This is guaranteed to lead to errors in application databases and possible loss of saves in games. Always use the "Extract" option in the storage settings.
Performance Comparison: Internal Memory vs. SD
It’s important to understand the difference in speed: Xiaomi’s built-in memory (UFS 2.1 or UFS 3.1) runs much faster than even the fastest microSD cards. Carrying heavy games can increase load times by 10-20%.
For lightweight applications, such as a calculator, an alarm clock, or simple utilities, the difference will be subtle. However, for resource-intensive tasks, navigation, and photo processing, internal memory remains preferred. Use the card intelligently, while distributing the load.
The critical factor is random read speed (IOPS): the internal memory is many times higher, which affects the responsiveness of the application interface. If you notice strong lags after transfer, it is better to return the program back.
💡
Optimal strategy: store photos, videos, music and rarely used applications on the memory card, and leave system programs and heavy games on the built-in drive.
