Xiaomi smartphones are famous for their functionality, but even modern models often do not have enough internal memory to store a huge amount of photos, videos and games. Owners of Redmi and Poco devices regularly face a shortage of gigabytes, which leads to slowdown and inability to install new applications.
The process of activating an external drive on Xiaomi devices may vary depending on the version of the MIUI shell or HyperOS. Sometimes the system automatically recognizes the media, but other times it requires manual user intervention to properly format and configure. In this article, we will discuss in detail all the stages of connection, from physical installation to software conversion to part of internal memory.
Competent setting SD-The card allows not only to store files, but also to run applications from it, which turns a budget smartphone into a powerful multimedia center. However, it is important to understand the difference between portable storage and internal memory, as choosing the wrong option can lead to data loss or reduced performance of the gadget.
Preparation for installation and physical connection
The first and most important step is to physically fit the memory card into your smartphone slot. In Xiaomi devices, the SIM card tray is usually combined, which requires careful placement of contacts. Careless handling can damage the contact group or the drive itself, so all actions must be done without unnecessary haste and effort.
To extract the tray, use a special paper clip that comes with the kit, or a thin needle. Press the hole next to the tray until it extends. It is important to correctly combine the card cutouts and tray, focusing on the pictogram that is struck on the metal. After installation, the tray should enter tightly and until the characteristic click, after which the device can be turned on.
💡
Use only high-quality UHS-I or UHS-II memory cards from trusted brands like Samsung, SanDisk or Kingston to avoid data loss and system failures.
Once turned on, the smartphone should beep or show a notification of the detection of a new device. If this does not happen, check the cleanliness of the contacts on the memory card, rubbing them with dry soft cloth. Sometimes oxidation or dust interfere with normal connection, and simple cleaning solves the problem of the lack of response of the system.
Primary setting and choice of operating mode
After a successful physical connection, the Android system on board Xiaomi will offer you the choice of how to use the new drive. You will be given two main options: use as a portable storage or as part of internal memory. The choice depends on your goals: if you plan to move the card to other devices often, choose the first option, if you need a place to play the second one.
Portable storage allows you to save photos, music and documents to a map, but it doesn't allow you to install applications there. This format uses the FAT32 or exFAT file system, which is compatible with most computers and TVs, and the data remains available even after you extract the card from your phone, which is convenient for fast file sharing.
The second option, known as Adoptable Storage, formats the card into an ext4 file system and encrypts it by binding it to a particular device, then the card becomes an integral part of the system, and you can install applications on it, transferring them from the main memory, but you can not extract such a card without losing data and resetting the settings without special manipulations.
When you select the internal memory mode, the system will warn you that all data on the card will be deleted, which is a mandatory procedure for creating a protected partition. If there are important files on the card, pre-copy them to your computer or cloud storage, as it will be impossible to restore them after formatting with standard means.
Formatting a map as an internal memory
The conversion process SD-The internal memory cards on Xiaomi smartphones require several sequential actions in the settings menu. First, go to Settings, then select About Phone and click on Storage. In the list that opens, find your memory card and click on it to access additional options.
In the drive management menu, select Format. The system will suggest you choose the formatting type: "Only for this phone" or "Use as portable storage." To expand the memory for applications, select the first option. Once confirmed, the process will begin, which can take from a few seconds to a couple of minutes depending on the size of the card.
☑️ Checklist before formatting
⚠️ Note: During the formatting process, it is strictly forbidden to remove the memory card or turn off the smartphone. Interrupting the recording of system files can lead to damage to the file table and complete inoperability of the drive.
Once formatted, the system will offer to transfer existing data (photos, music) to a new drive, and it is recommended to accept this proposal to free up precious space in the main memory for the operating system and application cache, which will ensure a more stable interface and faster launch of programs.
Transfer applications to SD card
One of the main goals of memory expansion is the ability to install heavy games and programs directly on an external drive. MIUI This process is automated, but requires prior activation of the internal memory mode. Once formatted successfully, the system will start to propose installing new applications on the internal memory. SD-default-card.
To transfer already installed applications go to Settings → Annexes → All applications. Select the program you want from the list, click on Memory, and select Change. In the window that opens, select Memory. SD-The map is a new storage location, and not all applications support this feature because of the limitations set by the developers.
| Type of application | Possibility of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| System services | Impossible. | Critically. | Keep it in mind. |
| Social media | Partially. | Average. | Can we move it? |
| Hard games | Completely. | Depends on the card. | Recommended |
| Messengers | Only data. | High. | Better in memory. |
It is worth considering that the speed of applications running with SD-The card is directly dependent on the speed class of the drive itself. Cheap cards can become a narrow neck, causing slowdowns in games or a long load of the program interface. A1 or A2, optimized for running applications.
Why can't some apps be moved?
Setup the camera and save files by default
For owners of Xiaomi smartphones with active photo and video shooting, it is important to set up automatic storage of materials on the camera. SD-This avoids overflowing internal memory and losing the ability to take new pictures at the most critical time, and is set up directly in the camera application, which is standard for the shell. MIUI.
Open the Camera app and click on the three-bar menu icon in the top right corner. In the list that appears, select Settings. Find Save in SD-Now all new photos and videos will be automatically recorded to an external drive, bypassing the internal storage.
A similar procedure is worth doing for instant messengers like Telegram or WhatsApp if you want to save media files from them to a map, and in the settings of these applications in the Data and Storage section, you can specify the save path, this is especially true for group chats, where hundreds of megabytes of images and voice messages accumulate daily.
💡
Automatic photo saving on SD-Card is the most effective way to prevent overflow of the main memory of the smartphone in the long run.
Note that when you are actively using serial or high-resolution (4K) video, the speed of the card may not keep up with the data stream. In such cases, the camera may suggest a decrease in quality or a temporary pause in recording. This is normal behavior for low-speed cards.
Removing errors and display problems
Despite the simplicity of the procedure, users often encounter situations where the memory card is not readable, displayed as empty or requires re-formatting.One common reason is the use of large-volume cards (over 128 GB) in older smartphone models that simply do not support such addressing standards.
If the system writes «SD-The card is corrupted" or "Not supported," try formatting it on your computer. To do this, connect the card through the card reader to your PC, open "My computer," right-click on the disk and select Format. As a file system for internal memory mode, it is better to choose exFAT, although when connecting to the phone, the system will still reformat the partition.
⚠️ Warning: If the smartphone stops seeing the card after long use, it may be that the contacts of the card have oxidized or erased. Try gently erasing the contacts with a pin, but act extremely carefully so as not to damage the metal layer.
In some cases, resetting your phone helps, but it's a last resort. Before you decide to reset completely, try checking the card on another device. If it doesn't work there, the drive probably malfunctions and needs to be replaced. Memory cards have a limited resource of overwrite cycles and can fail suddenly.
What to do if the sound is lost after installing the card?
Safe recovery and maintenance of the storage device
Properly extracting a memory card is key to its long life and data security. Unlike older phones, modern Xiaomi allows you to retrieve the card on the go, but only after software unmounting. If you just pull the card while you write the file, you can damage the file system and lose information.
For safe extraction, go to Settings → The phone. → Storage, press yours. SD-You can select Extract or Disable, and only after you have a notice that the card can be safely retrieved, use the paper clip to physically retrieve the tray, which ensures that all background recording processes are completed.
Check the status of the memory card regularly through the settings menu. MIUI can warn you of slow drive or read errors. If such messages appear often, you should consider buying a new, faster card, since the degradation of memory cells is inevitable when you use it.
