Xiaomi smartphones are known for their excellent cameras and affordable price, but even the most advanced models have limited internal memory. Owners of Redmi and Poco series devices often face a situation where the system reports a lack of space for new images, this is especially true for those who shoot in high resolution or record video in 4K format, where each file takes up a significant amount of space.
Fortunately, most of the modern devices of the Chinese manufacturer support the installation of microSD memory cards, which allows you to significantly expand the available space and store thousands of photos without the need to constantly delete old files or clean the cache of applications. Data transfer can be done either automatically or manually, depending on your preferences and shell version. MIUI.
In this article, we will discuss in detail all the available ways to transfer images to an external drive. You will learn how to set up a camera for automatic recording, how to move existing galleries and what nuances should be considered when choosing a memory card for your device. Proper organization of storage will prolong the life of your smartphone and relieve constant stress due to the lack of megabytes.
Selection and installation of memory cards in a smartphone
The first step to freeing up internal memory is to get a suitable storage device. Not all memory cards are equally useful for smartphones, especially if you plan to store photos and video from the camera. The speed of recording is critical: if the card is too slow, the camera may simply refuse to write to it or the shooting process will be interrupted.
Note the speed markings. For modern Xiaomi smartphones, the best choice is a Class 10, U3 or A1/A2 speed card, which ensures that the drive is able to handle the high-density data streams that occur when you take a photo or record a video.
Installation of the card is usually made in a combined slot, which also serves for the second slot. SIM-Be careful when removing the tray so that the mechanism is not damaged, and once installed, the system must automatically recognize the new medium and prompt it to adjust.
- 📏 Make sure the card size does not exceed the maximum supported by your smartphone model (usually up to 512GB or 1TB).
- 🚀 Choose cards marked “High Endurance” or “Industrial” if you plan to record video intensively.
- 💾 Formatting is best done by the phone itself to create the right file structure.
⚠️ Note: When formatting a memory card through Android settings, all data on it will be permanently deleted. If there are important files on the card, pre-copy them to your computer.

Set up automatic photo saving on SD-map
The most convenient way to solve the problem of space shortage is to set up the camera so that all new pictures are saved immediately to the external drive.In the shell of MIUI and the newer HyperOS, this feature is often turned on by default after installing the card, but its status is always worth checking.
To do this, open the Camera app and go to the settings menu by clicking on the three bars in the upper right corner. In the list of options, find the item "Save to the settings menu". SD-Map" or "Storage settings. Activating this switch will redirect the data stream directly to the external storage.
Note that some shooting modes may ignore this setting, such as Bokeh Portrait or RAW shooting, which are sometimes only stored in internal memory to ensure maximum processing speed by the processor, and features like Second Space or Application Cloning may have their own save path settings.
☑️ Checking camera settings
If you turn on this option, you still get your photos into internal memory, try restarting your device, and sometimes it takes time for the system to index the new drive and redistribute access rights to the file system.
Manual transfer of existing photos through the Explorer
If you already have a large number of photos in your internal memory, you can move them manually, and Xiaomi smartphones use the built-in File Manager app, which has a fairly wide functionality.
Open the app and go to Internal Storage or Device Memory, and you need to find the DCIM folder that houses the Camera folder, and that's where all the photos and videos you've taken are stored by default.
Select the files or folders you want with a long press. From the bottom menu, select Move (not Copy if you want to make room) and then go to the root of the memory card (usually indicated as SD card mi_sdcard1) And create a new folder there, for example, Photo_Archive, Not to mix files with system files.
- 📁 When moving large amounts of data (more than 10 GB), the process can take several minutes, do not interrupt it.
- 🔍 Use date sorting in the explorer to find old photos for archiving faster.
- 📤 For transferring video files, it is better to use batch sending, selecting them in groups of 50-100 piece.
⚠️ Note: Do not move system folders or files with extension.android_secure. This can lead to incorrect operation of applications that were installed on the memory card.
Once you have completed the operation, check that the files are opened in the gallery. If everything is displayed correctly, you can safely delete the originals from internal memory if you used the copy function instead of moving.
Use of cloud services and synchronization
An alternative to a physical memory card is the use of cloud storage, and Xiaomi is actively promoting the Mi Cloud service, which allows you to automatically upload photos to the cloud when you connect to Wi-Fi. This frees up space on the device, since the originals can be deleted, leaving only thumbnails.
But cloud technologies have limitations in terms of internet speed and free fare, and for users who want to have full control over their data and not depend on subscriptions, the combination of internal memory is a powerful tool. + physical SD-The map is the most reliable solution.
Many users also use third-party services such as Google Photos or Yandex.Disk, which can automatically back up and offer the “Free Space” feature, removing from the device those pictures that are already uploaded to the cloud.
It's important to understand the difference between synchronization and simple storage: When you use the cloud, you depend on the company's servers, whereas the memory card is always in your hands, and physical storage is the only way to guarantee access to data without the Internet and the risks of blocking your account.
Comparison of data storage methods on Xiaomi
To make it easier for you to decide on the optimal memory management strategy, let’s compare the main options available, each with its advantages and disadvantages, which become noticeable when you use a smartphone actively.
The UFS (Universal Flash Storage) internal memory used in modern Xiaomi has a high read and write speed, which allows for fast interfaces and instant application launches, but its scope is limited and cannot be expanded without complex technical manipulations.
External memory cards, even high-speed ones, are inferior to internal storage in performance, running applications from them can be slower, and recording heavy 4K video sometimes causes twitches, but storing static files — photos, music, documents — is ideal and cheap.
| Parameter | Internal memory. | Memory card (SD) | Cloud storage |
|---|---|---|---|
| Speed of operation | Very high. | Medium/High | Depends on the Internet. |
| Cost of expansion | Only buying a new phone. | Low (card price) | Monthly subscription |
| Risk of data loss | When the phone breaks down | In physical maps. | When you hacked an account |
| File availability | Only on the device. | On any device with an adapter | Wherever there is a network |
When you choose between these options, you have to be mindful of your needs. If you're a professional photographer shooting on your phone, internal memory is the buffer, and if you're an amateur taking thousands of pictures of children and travel, the memory card is the lifeline.
Possible problems and ways to solve them
Users may encounter various errors during operation. One of the most common is a message «SD-The card is corrupted" or "Formatting required. "That doesn't always mean the drive is physically broken.
Often the problem lies in the file system. Android prefers the format exFAT or FAT32. If the card was formatted in NTFS (Windows standard), the phone can see it, but can not write data to it, in which case you need to re-format the smartphone.
Another cause of failure may be incorrect map extraction, and although current file systems are error-resistant, abruptly pulling a card while writing can damage the partition table, in which case error checking through a computer or re-formatting can help.
- 🔄 If the photo is not saved, check if the memory card is full.
- 🛡️ Antivirus scanners sometimes block recording on external drives, try to turn off protection for a while.
- 📱 Make sure that the camera and gallery app access the device memory in the permission settings.
💡
If the phone has stopped seeing the memory card, gently wipe the contacts on the card itself and in the phone slot with dry soft cloth. Contact oxidation is a common cause of connection loss.
In rare cases, the problem may be caused by a software failure of the MIUI shell itself. Cleaning the cache of the Media Scanner or Media Storage application through the application settings menu can help the system re-index files.
💡
Regularly backing up important photos to your computer or the cloud is the only guarantee that you will not lose memories in the event of a sudden breakage of your memory card or smartphone.
