Owners of Xiaomi and Redmi smartphones often face a situation where the device’s internal memory is overflowing, and the system insistently asks for space. Most of the volume is occupied by photos and videos, especially if you like to shoot in high resolution or 4K format. Transferring media files to an external drive becomes the only reasonable solution to continue shooting without deleting old archives.
Unfortunately, modern versions of the shell MIUI HyperOS does not always offer a simple "Save to" switch. SD-This is done to improve the speed of work, since the internal drive is usually faster than external cards. However, there are several proven methods to circumvent this limitation and make the phone write files immediately into external memory.
In this article, we will discuss all the current ways to solve the problem, from standard system settings to the use of third-party applications and even system codes. You will learn how to format the drive correctly to avoid write errors, and which memory cards are best for Xiaomi smartphones. Following the instructions will help you forget about the message “Memory is full” at the most inopportune time.
Preparation of a memory card and smartphone
Before you go to the settings of the software part, you need to make sure that the physical compatibility and serviceability of the media. Poor or damaged microSD card can cause the camera to freeze or data loss. First of all, check whether your Redmi model supports the installation of memory cards, as some new flagship lines are deprived of the corresponding slot.
Insert the card in the tray of SIM cards and wait for the notification system. If the phone offers to format the drive, be sure to agree, previously saving important data on the computer. For stable camera operation, it is recommended to choose cards of class speeds at least Class 10 or UHS-I, since recording video requires a high data flow rate.
⚠️ Note: Using cheap memory cards from nameless brands can cause video recordings to suddenly stop or file damage.It is recommended to purchase media from trusted manufacturers such as SanDisk, Samsung or Kingston.
Once installed, go to the storage settings and check the amount of available space. The system must correctly display the card as a removable medium. If the device sees the drive but does not allow files to be written to it, you may need to re-format it in the FAT32 or exFAT file system.
Set up a standard Camera application
Most current versions of MIUI have hidden the direct option of changing the save path, but in some interface modifications or on certain Redmi models, this feature is still available through the standard menu. To check if this is possible, open the Camera app and go to the settings menu by clicking on three bars in the corner of the screen.
In the list that opens, look for a storage or memory item that might be called "Save on the computer." SD-If you find a memory card, just activate it, and then all the new images will be automatically sent to the external drive, bypassing the internal memory.
If there is no standard switch, don't get upset. There are workarounds that don't require superuser rights. One effective method is to use the Memory Extension feature if it is available in your model, although it is more likely to work with system files.In some cases, cleaning the Camera app cache through the Settings menu helps. → Annexes → All applications → Camera. → Clean up.

Before changing your camera settings, take a few test shots and check where they are saved to be able to compare the result before and after.
Use of third-party applications for shooting
When regular funds fail, third-party apps from the Google Play Market come to the rescue. There are many cameras that have flexible file-saving settings. One of the most popular and functional solutions is the Open Camera app, which is completely free and free of ads.
Once you install the Open Camera, you need to go to its settings. Find the Settings section (the gear icon) and scroll to "Other Settings." That's where the "Preferred Storage" option is. Select yours. SD-A map from the list of available devices. Now all photos and videos will be written there by default.

- 📷 Camera MX — popular application with a powerful editor and the ability to choose a saving path.
- 🎥 HD Camera – a utility focused on video shooting, allowing you to flexibly manage storage.
The other advantage of using third-party software is access to additional quality settings and compression formats, so you can adjust white balance, ISO and shutter speed in more detail than standard software allows, and this is especially true for mobile photography enthusiasts who want control over the shooting process.
☑️ Open Camera setup
Activation method through engineering menu
For more experienced users, there is a way to activate the hidden function of saving on the SD-This method does not work on all Xiaomi models, but it is effective on many devices with MediaTek processors and some Qualcomm. Be careful when performing these actions, as changing other parameters can lead to unstable phone operation.
To enter the menu, type a special code in the phone book. The most common combinations for Xiaomi are: ##6484## or ##4636##. If none of the codes work, try downloading the Engineering Mode app from the Play Market.
The sequence of actions in the menu:
1. Common
2. Camera Setting
3. Save to SD Card -> Enable⚠️ Note: The interface of the engineering menu may vary depending on the Android version and the processor. If you are not sure about your actions, it is better not to change the settings marked as "Debug" or "Test».
Once you activate the option, restart your smartphone and check the camera. If the method works, the gallery will tag new photos or physically reside in the DCIM folder on the external media, which allows you to use the standard camera interface that you are used to, but with a modified recording path.
Comparison of data retention options
The choice of method of saving photos depends on your priorities: speed, user-friendliness or additional features. The standard application works fastest because it is optimized by the manufacturer, but often lacks flexibility. Third-party cameras give more control, but can consume more battery resources.
The table below compares the main characteristics of different approaches to organizing photo storage on Xiaomi Redmi, which will help you choose the best option for your use case.
| Parameter | Standard camera. | Third-party software (Open Camera) | Engineering menu |
|---|---|---|---|
| Difficulty setting up | Low. | Medium | Tall. |
| Stability of work | Tall. | Medium/High | Depends on the model. |
| Photo quality | Optimized. | Customizable | Standard. |
| Risk of error | Minimum | Low. | Medium. |
If you are critical to the speed of launch and shooting “on the go”, it is better to try to configure a regular application. If you plan to shoot long-term on the trip and the memory card is the main storage, then installing a specialized application will be a more reliable solution.
What if the photo is stored in the internal memory?
Transfer of existing photos
Customizing the save path solves the problem of future images, but does not free up space from the already accumulated gigabytes of archives. To transfer the old gallery, you can use the built-in file manager Explorer, which is in every Xiaomi smartphone. This process is simple and does not require a connection to a computer.
Open the Explorer app and go to Images or Internal Drive. Find the folder DCIM, And inside it is Camera. Select all the photos you want to move. In the bottom menu, select Move or Copy, and then select the target folder on the top of the menu. SD-map.

- 🖼️ Go to the folder. DCIM/Camera photo-access.
- ✂️ Select files and click “Move».
- 💾 Select the root of the memory card or create a new folder there.
When moving a lot of data, it can take a few minutes. Don't turn off the screen or run heavy applications in the background so as not to interrupt the operation. Once completed, check that the files are correctly displayed in the gallery from the new storage location.

Regular cleaning of internal memory from old videos and photos is the best prevention of slowing down of the Xiaomi smartphone.
Possible problems and solutions
Users may encounter a variety of errors during the setup process, the most common being a message that the memory card is damaged or cannot be used to write, often because the card file system is not readable by Android, or it has been formatted as internal memory on another device.
If the camera writes “failed to save,” try to reduce the quality of video recording from 4K to Full HD. Low-speed memory cards simply do not have time to record the high-resolution data stream, and the problem can lie in overflowing the file table, which is solved by formatting the card on the computer in exFAT format.
⚠️ Warning: Never remove a memory card during the camera operation or writing process.This is guaranteed to damage the last recorded file and may cause file system errors.
In rare cases, after updating the firmware, the camera settings are reset. If you used a third-party app, check its permissions in the Android settings menu. The system could automatically revoke access to files on external media for security purposes after the update.
