Xiaomi’s modern smartphones are famous for their excellent cameras that allow high-resolution images. However, as the quality of photos and videos increases, the device’s internal storage is quickly consumed. Owners often face a situation where the system notifies about the lack of space, blocking the ability to take new pictures or install applications.
The solution to this problem is the use of a microSD memory card. Transferring media files to an external medium not only frees up precious space in the system, but also ensures the safety of data in the event of a reset of the phone settings. In this article, we will discuss all the current ways to move the gallery to the SD-map.
The process of optimizing memory in the MIUI shell or HyperOS has its own features that differ from pure Android. It is important to understand the difference between transferring already finished images and setting up automatic saving of new frames immediately to the flash card.
Preparation of a memory card and installation in a smartphone
Before you start manipulating files, you need to make sure that the drive is serviceable and compatible. Not every memory card will work correctly with your device, especially if it is old models or, conversely, the latest flagships with high write speeds. Formatting is the first and mandatory step that will prepare the media for work.
Insert the card into the slot, which is usually in the tray for SIM-If you find the drive, you'll be asked to configure it. If you don't get an automatic notification, go to the settings menu. → The phone. → Warehouse or go to memory management immediately.
⚠️ Note: Formatting completely removes all data from the card. If it has important files, pre-copy them to the computer.
For stable camera operation, it is recommended to choose cards of a speed class at least Class 10 or UHS-I. Slow drives can cause delays when shooting serial images or recording high-resolution video. Once installed, the system will display the total amount of available memory, summarizing internal storage and external media.
Automatically save new photos
The most effective way to avoid overflowing internal memory is to set the camera to immediately save new images to an external medium. In Xiaomi’s standard Camera app, this feature is often hidden in additional settings. Open the app and tap three horizontal bars in the upper right corner of the screen.
In the menu that opens, select Settings. Scroll down to the storage section to the option "Save to Settings." SD-Map" or "Preferred save location." Activate the switch, and all future frames will be recorded directly to the flash drive.
💡
Use memory cards up to 256GB for maximum compatibility, even if the phone supports a larger volume, which will reduce the risk of file system errors.
It is worth noting that some shooting modes, such as slow-motion video or special filters, can still save data to internal memory due to write speed limits.
- 📸 Open the Camera app and log in to the settings menu.
- 💾 Find the item "Save to" SD-map and activate it.
- 🎥 Check if the setting is maintained after the device restarts.
- ⚙️ Make sure that the memory card is defined as the main storage for media in the system settings.
Transfer of existing photos through the Explorer
If you already have a gallery of images in your internal memory, you can move them manually, and Xiaomi smartphones have a powerful file manager installed, launch the Explorer app (or Files) and go to the Internal Shared Drive section.
Find the DCIM folder, and inside it is the Camera, and that's where all your photos and videos are stored by default, select the files you want with a long press, or use the "Select All" function in the control menu, then click "Move" or "Copy" button.
☑️ Algorithm of file transfer
Once you have selected the action, the system will suggest you specify the destination. SD-Create a new card or folder, for example, Photos_Archive, And you can confirm the operation. The process of copying a lot of data can take time, don't interrupt it.
⚠️ Warning: When moving large amounts of data (over 10 GB), make sure your smartphone battery is above 40% so that the device doesn’t turn off at a critical moment.
Once the operation is complete, it is recommended to check the integrity of the files in the new location. Open the gallery and make sure the thumbnails are displayed correctly. If you used the Copy feature, remember to delete the originals from the internal memory to make room.
Use of the Gallery app for sorting
The built-in MIUI Gallery app allows you to manage albums and move them between storages without using a file manager, a method that is more convenient for users who are used to working with a visual interface. Open the gallery and go to the Albums tab.
Select the album you want to move. Click on the three dots in the upper right corner or select the menu item "Information" or "Album Settings." If the memory card is installed and defined by the system, the option "Move album" or "Change save path" may appear.
However, it is worth considering that the functionality of the standard gallery can be limited depending on the version of Android. In new versions of the OS, direct movement of entire albums through the gallery interface is sometimes not available, and the system offers only to create a copy.
Why can't the albums move?
To mass sort photos by date or event before transfer, you can use the function "Hide" or create new albums. SD-not to turn it into a messy dump of files.
Comparison of Storage Methods: Internal Memory or SD
The choice of file storage space affects not only the free space, but also the speed of the smartphone. Internal memory (UFS or eMMC) usually works much faster than most memory cards, this affects the speed of opening heavy photos, processing HDR and recording 4K video.
Use of the SD-The maps are ideal for archival data, old photos and videos that you rarely view, but running apps or working with live photos is better left on the internal drive. Understanding these differences will help optimally allocate the resources of the device.
| Parameter | Internal memory. | Memory card (SD) |
|---|---|---|
| Read/write speed | High (up to 2000 MB/s) | Medium (up to 100-170 MB/s) |
| Reliability of storage | High (sold on board) | Medium (risk of physical damage) |
| Impact on the system | Critical to the OS | Used for media files |
| Possibility of replacement | No. | Yeah, anytime. |
If you’re actively shooting 4K video, it’s a good idea to leave the recording on internal memory to avoid jerks and artifacts while recording.Memory cards may not keep up with the real-time data stream, which will cause the recording to stop.
💡
The optimal strategy is to store current projects and applications on internal memory, and send archives and rare files to the public. SD-map.
Solutions and formatting as internal storage
Sometimes users want to make a memory card an extension of internal memory so that the system can decide where to write the data. In MIUI, this feature is called "Memory Extension" or formatting as internal storage, and you can find it in the storage settings by selecting the card and clicking "Format".
It's important to understand the implications: once formatted, the card is encrypted and linked to a particular phone, and it's not possible to extract and read data from that card on another device or computer without formatting again, and this creates a risk of data loss when the smartphone breaks.
If the memory card is no longer identified or files are corrupted, try formatting in compatibility mode (like portable storage).
- 🔧 Go to Settings. → The phone. → Warehouse.
- 📀 Choose. SD-map and click on "Settings of the storage».
- 🗑️ Select “Format” and follow the instructions on the screen.
- ⚠️ Remember that all data will be destroyed in the process.
⚠️ Warning: Do not remove the memory card while the camera is running or recording sound, this may cause file system damage and data loss.
If you have persistent reading errors, replace the card with a better one. Cheap drives from unknown brands often fail when you actively record large amounts of data, which is typical of modern smartphones.
