Owners of Xiaomi, Redmi and Poco smartphones often face a lack of built-in storage, especially if the device was purchased in the basic configuration. Overflowing memory leads to reduced system performance, inability to install updates and problems with creating new photos. That is why the issue of transferring data to an external medium remains one of the most pressing for users of the MIUI shell and the new HyperOS.
Modern versions of the Android operating system, which runs the phones of the Chinese manufacturer, have significantly changed the logic of working with the file system. If previously you could move all applications in one move, now the process requires more subtle configuration and understanding of security limitations.
In this article, we will explore all the available ways to save content to an external drive, from standard camera settings to advanced methods through the engineering menu, learn how to avoid common formatting errors and why some programs categorically refuse to work outside of internal memory.
Preparation of memory card and initial setting
Before the system can work properly with the new drive, it must be properly installed and formatted.Put the microSD card into the tray of your Xiaomi smartphone, observing the correct orientation of contacts. Once connected, the device usually automatically suggests formatting the media, but this step can be done manually through settings.
To do this, go to the Settings menu, look for the About Phone or Storage section (depending on the shell version). Here you will see information about the occupied space and the connected drives. SD-maps to open the control menu.
💡
Use UHS-I or UHS-II memory cards from trusted brands like SanDisk or Samsung to avoid delays when recording video in 4K.
The critical step is to choose the type of formatting, and the system will offer two options: use as a portable storage device or as part of internal memory, the first option allows you to easily transfer files to other devices, the second option is to encrypt data, making the card unreadable on other phones without re-formatization.
☑️ Primary setting SD-map
Note that the formatting process will completely destroy all the data on the media. If there were important files on the map, copy them to the computer beforehand. Once the procedure is complete, the system will create the necessary folder structure, including Android, DCIM and MIUI.
Setup of the camera to record SD-map
The most voluminous content users generate is photos and videos. The camera on Xiaomi smartphones defaults to storing all the pictures in internal memory, but this setting is easy to change. Open the Camera app and go to the settings menu by clicking on the three horizontal bars in the upper right corner of the screen.
In the list of parameters, scroll down to the Save on SD-Activate this switch. Now all new photos and videos will be automatically recorded to an external drive, freeing up precious space in the system partition.
⚠️ Note: When shooting high-resolution video (4K or 8K) Or when you use Portrait mode, the camera can ignore the settings and save files to internal memory, which is due to high write speeds that cheap memory cards can not provide.
It is important to understand that changing this setting does not affect the pictures already taken. Old photos will remain in the memory of the phone unless you transfer them manually. Also, it is worth considering that when you use zoom or serial shooting, the clipboard can overflow faster if the write speed on SD is lower than the internal memory speed.
Some users have noticed that once this function is enabled, the gallery can process thumbnails longer, which is normal for the system to index a large number of new files on an external medium, and after a few minutes, the application stabilizes.
Transfer of installed applications and games
The issue of installing apps on a memory card in modern versions of Android is not as clear as in older versions. Google has implemented security restrictions that prevent you from simply transferring executables of programs. MIUI It is possible to transfer part of the data.
Go to Settings. → Annexes → All applications. Select the game or program you want from the list. If the application supports portability, you'll see a Move to the Mode button. SD-map (or modify) → If the button is missing or inactive, the developer has banned the transfer.
| Type of application | Possibility of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| System services | Impossible. | High. | Leave it in your internal memory. |
| Social media | Partially (cache) | Average. | We can move data. |
| Hard games | Depends on the game. | Critical. | Better leave it inside. |
| Office programmes | Oftentimes. | Low. | Pass it boldly. |
It's worth noting that even if you successfully transfer some files, you still have to keep the internal storage, which is necessary to ensure that the operating system works smoothly and that programs run quickly. It's almost impossible to completely free the system partition by moving all applications without obtaining Root rights in today's environment.
Using the Adoptable Storage feature, which turns the card into a full-fledged extension of the system, on Xiaomi smartphones is often hidden or unstable. ADB-commands can cause a cyclic reboot of the device if the memory card does not have a high random read/write rate.
Working with files through a conductor
For manually managing documents, music and video in Xiaomi smartphones, a powerful tool is preinstalled – Explorer. This standard application allows you to easily move files between internal memory and the user’s computer. SD-Find the app icon in the Tools folder or on the desktop.
The interface is divided into categories. To move files, go to Internal Drive. Select files or folders with a long press. From the bottom menu, select Move or Copy, and then go to the section. SD-map and specify the target folder.
The secret to quick sorting
Multimedia folders are worth paying special attention. It often happens that messengers like WhatsApp or Telegram store the received files into internal memory. In the settings of the messengers themselves, you can specify the way to save, or regularly clean Download and MIUI folders manually.
When dealing with large amounts of data (for example, transferring several gigabytes of video), the phone can get hot. This is a normal reaction of the memory controller and the processor. Do not interrupt the copying process, even if it seems to be suspended - an interruption can damage the file structure.
Use as a USB-storage
One of the handy features of Android is the ability to use the phone as a card reader for a computer without removing the card. USB-cable and in the notification of the connection mode select File Transfer (MTP).
There will be two separate devices on the computer in My Computer: the phone’s internal memory and yours. SD-You can work with files on a map directly, like a flash drive, by copying documents, music or movies.
⚠️ Warning: Do not remove the memory card through the Android menu while the phone is connected to the computer in file transfer mode.This can cause file system error and data loss. USB-cable.
This method is especially useful if you need to quickly throw a heavy movie on your phone to watch or update maps in the navigator. USB-port of your phone (usually) USB 2.0 in budgetary models or USB 3.0/3.1 flagship).
Solving problems and errors
Despite the ease of customization, users often encounter errors such as «SD-The card is corrupted" or "Formatting required" most often this indicates an exFAT file system or "Formatting required. NTFS, which the phone cannot read without special drivers, or logical failure.
Try formatting the card again directly on your phone by selecting the FAT32 file system (for cards up to 32 GB) or exFAT (for cards up to 32 GB). If the error repeats, check the card on your computer with the chkdsk or SD Formatter utility.
Another common problem is spontaneous card shutdown, which can be due to oxidation of the contacts in the tray. SIM-Wipe the contacts of the card with a soft eraser and blow the phone slot with compressed air. In rare cases, re-painting the contacts of the card with a thin layer of conductive glue helps, but this is a risky method.
💡
Stability of work SD-The quality and speed of the card is directly dependent on the quality and the class of the card, and cheap cards without a brand often fail after a few months of active recording.
If your phone stops seeing the card after you update, check the permission settings for the Media Service system application, sometimes after the update, external storage permissions are reset.
