Xiaomi smartphone owners often face the problem of lack of internal memory, especially if the device is equipped with a modest 32 or 64 GB. The microSD card seems to be the obvious solution, but MIUI (branded shell Xiaomi) imposes a number of restrictions on its use. Unlike "pure" Android, you can not just migrate all applications or automatically save photos to an external drive. Why this happens and how to circumvent these restrictions, let's go into detail.
The main problem lies in the policy of Google and Xiaomi: since Android 6.0 Marshmallow, the system ceased to support full formatting of memory cards as internal storage (Adoptable Storage), manufacturers including Xiaomi have gone even further, blocking this feature in the system. MIUI But there are workarounds, from manually configuring file retention to using hidden shell functions. SD-map, and which โ not, and how to configure the system to maximize the use of external memory.
What files can be saved to a memory card in Xiaomi
Not all data types in MIUI support saving to an external map, so let's see what can be transferred without problems and what will require additional manipulation.
Without restrictions on the memory card, the following are stored:
- ๐ท Photos and videos from the standard Camera app (starting with the MIUI 12)
- ๐ต Music and audio files (via apps like Music or Spotify)
- ๐ Documents and downloads (files from the browser, Telegram, WhatsApp)
- ๐ฎ Cache of some games (such as Genshin Impact or Call of Duty Mobile)
Difficulties arise with:
- ๐ฑ Applications: most of them can only be partially transferred (cache, not the program itself)
- ๐ System updates: MIUI Never keep them on. SD-map
- ๐ System files: transfer may cause crashes (e.g. files.android_secure)
It is important to understand that even if you transfer the application to the map, its performance may fall โ SD-lower-class A2 It is not designed for frequent reading/write. For games and heavy programs, it is better to use internal memory.
How to Configure Photo and Video Saving on a Memory Card
Standard appendix Camera in MIUI It allows you to save media files on SD-This is a map, but this option is often hidden or reset after updates:
- Open the Camera app.
- Touch the gear badge (โ๏ธ) top-right.
- Go to the camera settings section โ Save.
- Select Memory for Photo or Memory for Video (depending on the model).
- Indicate. SD-Card instead of Internal Memory.
If the option is not on the menu, check:
- ๐ Is the memory card connected (sometimes the system doesnโt see it due to poor contact)
- ๐ฑ Is the card formatted as a portable storage (rather than as an internal memory)
- ๐ Restart your smartphone โ sometimes the settings are only applied after a reboot
๐ก
If after transferring photos disappear from the gallery, clear the cache of the Gallery application in the settings or restart the phone.
For models with MIUI 13/14 (e.g. Redmi Note 11, POCO X4 Pro) the path may be different:
Camera โ Settings (โ๏ธ) โ Additional โ Save โ SD- MapIf the option to save to the card is missing even after these manipulations, then your Xiaomi model blocks this feature at the firmware level, in which case only manual copying of files through Explorer or Google Photos will help.
Transfer of applications to SD-map: what works and what doesn't
Unlike older versions of Android, MIUI severely limits the portability of apps to an external map.
- Open Settings โ Applications โ Application Management.
- Select the app you want (like Facebook or VK).
- Press Warehouse.
- If the option to Change is available, select SD-map.
But there are nuances:
- โ Not all apps support portability โ many (like WhatsApp, Instagram) block this feature.
- โ ๏ธ Only a part of the data (cache, media) is transferred, not the application itself.
- ๐ข Performance may fall, especially if the class card A1 lower.
Forcing applications to be ported requires root rights or special utilities like App2SD, but it is risky:
โ ๏ธ Attention: Use App2SD or similar programs without root rights can lead to data loss or a cyclical smartphone reboot.
Alternatively, install applications directly on the map via ADB (for advanced users).
adb shell pm set-install-location 2This command will force the system to install new applications on the SD-The default card. To get it back, use it:
adb shell pm set-install-location 0Backup data | Check the card class (A2 recommended | Clear the app cache |Reboot the smartphone after transfer-->
Formatting a memory card as an internal storage: pros and cons
In older versions of Android (6.0-8.1) was the Adoptable Storage feature, allowing you to "tether" SD-The card as part of the internal memory. MIUI This option is disabled by default, but it can be activated via ADB Or third-party utilities?
| Advantages | Deficiencies |
|---|---|
| ๐ Single storage for applications and files | โ ๏ธ The card becomes โtiedโ to the phone โ it will not be read on other devices |
| ๐ฑ You can install applications directly to SD | ๐ข Speed is lower than internal memory (even with cards) UHS-I) |
| ๐พ Save space in internal memory | ๐ง If the card fails, the system may stop booting. |
| ๐ Data is encrypted (enhanced security) | ๐ After the map is removed, the applications will stop working. |
To format the card as an internal memory:
- Connect. SD-phone-card.
- Go to Settings. โ Memory. โ Settings (โ๏ธ) โ Formatting as an internal.
- Follow the instructions of the system (the process will take a few minutes).
If you donโt have the option on the menu, use ADB:
adb shell sm set-force-adoptable true
adb shell sm partition disk:179,64 privateWhere 179,64 โ Card ID (you can find it through the command adb shell ls) /dev/block | grep -i mmc).
โ ๏ธ Warning: Once formatted as internal storage, the card cannot be retrieved without resetting the phone to factory settings.
Optimizing the use of memory cards: tips and tricks
Even if you have transferred some of the data to SD-It can be used more efficiently. Here are some proven ways:
- ๐ Separating files by folder: Create separate directories for photos (DCIM), Music, documents, and so on, that makes it easier to search and back up.
- ๐ Automatic cleaning: in Settings โ Memory. โ Clean up the option to delete unused files from SD-map.
- ๐ฑ File Manager: Applications like Mi File Manager or Solid Explorer allow you to set up automatic saving of downloaded files to the map.
- โ๏ธ Hybrid Storage: Combining SD-Map with cloud services (Google Drive, Mi Cloud) for backups.
To speed up the memory card:
- ๐ง Format it in exFAT (if the phone supports it) and it will reduce fragmentation.
- ๐ Check the vacant space regularly: if less than 10% is left, productivity drops.
- ๐ซ Avoid cheap cards without class labeling (A1, A2, UHS-I).
Critical information: microSD cards from unknown brands (such as NoName or SanDisk fakes) often have less than the actual volume claimed. H2testw (Windows or SD Insight (Android) before use.

Frequent problems and their solutions
When working with memory cards in Xiaomi, users encounter typical errors.
1.The phone doesn't see. SD-map
Possible causes and solutions:
- ๐ Bad contact: Remove the card and insert again (sometimes cleaning the slot with alcohol helps).
- ๐ฑ Incompatible format: format the card into FAT32 or exFAT via computer or computer.
- ๐ง Failure in MIUI: Restart your phone or reset your Warehouse settings in Settings โ System system โ Resetting settings.
2. Applications are not portable to the map
If the button Change in the application settings is inactive:
- ๐ Check if the app supports portability (many games and social networks do not).
- ๐ Update. MIUI Up to the latest version โ in new firmware sometimes expand the possibilities.
- ๐ ๏ธ Use it. ADB for forced transfer (see section above).
3. The memory card became "raw"
If the system offers to format the card with each connection:
- ๐พ Try scanning it on your computer with the help of CHKDSK (Team: chkdsk X: /f, where X is the letter of the disk).
- ๐ง If it doesnโt help, format the map in FAT32 through SD Formatter (official utility) SD Association).
- โ ๏ธ If the card is physically damaged, Recuva or PhotoRec can help restore the data (but the chances are low).
If none of the methods worked, the card probably failed, in which case it is better to buy a new one from well-known brands (SanDisk, Samsung, Kingston).
