Modern Xiaomi and Redmi smartphones offer great specs, but even 256 GB of internal storage is sometimes not enough for a huge number of high-resolution photos, 4K-It's in these situations that the microSD card comes to the rescue, allowing you to expand the useful space of the device without buying a new model. However, just inserting the drive into the slot is only half the battle, because the Android system and the shell. MIUI Require the right configuration for optimal operation.
In this article, we will discuss in detail how to properly configure memory in a Xiaomi phone to a memory card to avoid problems with performance and data loss. You will learn about the differences between the modes of operation of the drive, learn how to transfer existing files and understand why some applications refuse to work with external storage.
Cheap memory cards of unknown brands can cause system freezes, slow uploading of photos and sudden loss of important documents. It is recommended to use UHS-I or UHS-II speed cards from trusted manufacturers such as SanDisk, Samsung or Kingston to ensure stable data exchange with the smartphone processor.
Preparation of memory card and compatibility check
The first step before implementing a new drive into your smartphone ecosystem is physical verification and formatting. The memory card slot in Xiaomi devices is usually combined with a tray for the device. SIM-So you need a paper clip to extract the card, so make sure you insert the card with the correct side, because the wrong position of the contacts can cause mechanical damage to the reader.
Once you install the map, Android will automatically detect the new device and suggest you set it up, and at this point, it's critical to choose the right type of use: If you plan to store only media (photos, videos, music) on the map, choose Portable Storage mode. If you need to free up internal memory by installing apps, you'll need an Internal Storage mode that will format the map completely and encrypt it to work only with this phone.
⚠️ Warning: The process of formatting the memory card to "Internal Storage" will completely destroy all data on it. Be sure to back up important files on your computer before you start setting up.
The speed of the card directly affects the speed of the entire smartphone. If you use the drive to run applications, low write speed can lead to “freezes” in games and long downloads of programs. You can check the current read and write speed using specialized slits, such as the A1 SD Bench or AndroBench, available on the Google Play store.
Instructions for formatting in internal storage mode
To turn a regular flash card into a full-fledged extension of system memory, a series of sequential actions must be performed in the settings menu, a process called adaptive storage, which allows the system to manage files more flexibly, spreading the load between the embedded chip and the external drive.
Follow the following steps to activate the mode:
- 📱 Go to the settings of your Xiaomi smartphone.
- 💾 Select About Phone or immediately go to Advanced Settings (depending on version) MIUI).
- 🔍 Find the Warehouse menu and click on it.
- 💿 In the list of available drives, select your memory card SD.
- ⚙️ Click on three dots in the corner of the screen and select Storage Settings.
- 🔄 Select the option to Format as internal storage.
Once confirmed, the system will begin the process of formatting and encryption, which can take anywhere from minutes to half an hour, depending on the size of the card and the speed of its operation, at which time it is strictly forbidden to remove the card or turn off the phone, as this can lead to damage to the file system and data loss.
☑️ Checklist before formatting
When formatting is complete, the system will suggest moving existing data (photos, applications) to a new drive. It is recommended to agree to transfer media files to immediately free up space.
Transfer photos and videos in the gallery Xiaomi
Most of the memory on smartphones is usually taken up by photos and videos. Cameras of modern Xiaomi shoot in high resolution, and one minute video in 4K can weigh several hundred megabytes. To automate the process of saving new images immediately to the map, you need to change the camera settings.
Open the Camera app and click on the menu (three bars) in the top corner. Go to Settings and find the switch Save to SD-Activate it. From now on, all new images and videos will be recorded by default to an external drive, bypassing internal memory.
To transfer an existing gallery, use the built-in file manager. MIUI Or the Conductor. DCIM In the internal storage, highlight all the contents and select Move. SD-This process may take time, but it's guaranteed to free up gigabytes of space.
Why are some photos not being transferred?
It's important to note that when you move a lot of data, the phone can get hot, and that's a normal reaction of the processor and the memory controller to the intense work, and if the device gets too hot, pause the file transfer to let the components cool down.
Installation and transfer of applications to SD-map
The issue of installing apps on a memory card remains one of the most challenging in the Android ecosystem.Since Android 6.0, Google has restricted direct access to the external drive for security purposes.However, if you format the card as internal storage (see section above), the system itself will suggest transferring the application data.
If automatic transfer does not occur, you can try to do it manually through the settings:
- Go to Settings → Apps.
- Select All Apps and find the desired program.
- Press Memory.
- If transfer is possible, the Change button will be active. Press it and select. SD-map.
Unfortunately, many app developers block the ability to install on an external drive. SD-The card is still inferior to the speed of the built-in memory eMMC or UFS, This can affect instant messengers, banking apps, and heavy gaming, and some widgets and services may stop working properly when ported.
| Type of application | Recommended seat | Reason. |
|---|---|---|
| Social media | Internal memory. | Requires quick access to the cache |
| Hard games | Internal memory. | High speed of loading textures is required |
| Office documents | SD-map | Rare use, high volume |
| Offline maps (Navitel) | SD-map | Maps take up a lot of space. |
💡
Use the “Clean Up” function in the “Security” application before transferring applications to delete temporary files and speed up the data migration process.
Working with files through MIUI Explorer
The standard file manager in the MIUI and HyperOS shell provides powerful tools for managing files. It allows you not only to move files, but also to sort them by type, date or size. To use memory efficiently, it is useful to know where the data of various applications is stored.
For example, downloaded files from Telegram or WhatsApp messengers are often duplicated in the gallery, taking up extra space. You can go through the Explorer on the Android/media path and find the folders of the corresponding applications, here you can safely delete the cache of videos and documents that you no longer need, or move them to the memory card in the archive folder.
And you can also use the Explorer to hide files. You can create a password-protected folder on the file. SD-And even if the phone gets into the wrong hands, without a password or fingerprint, that data is not accessible because the encryption is tied to your account.
⚠️ Note: When you delete system folders or files with unknown destination through Explorer, there is a risk of malfunctioning applications%.
For advanced users, the ability to connect a smartphone to a computer in file transfer mode (MTP) is available, which allows you to manage files on a memory card through the usual Windows or macOS interface using drag-and-drop, which greatly speeds up the process of sorting large archives.
Possible problems and ways to solve them
Despite the ease of customization, users may encounter a number of difficulties"SD-Card damaged" or card suddenly disappearing from the system, often due to oxidation of contacts or improper extraction of the card without first turning off the menu.
If the card is no longer defined, try the following:
- 🔄 Reboot your smartphone with a map installed.
- 🧹 Gently wipe the contacts of the memory card with a soft dry cloth.
- 📵 Remove the card, turn off the phone, insert the card back and turn on the device.
- 🛠 Try formatting the card on your computer in the exFAT file system (for 64GB and higher cards).
Another common problem is low recording speed, and if the phone stutters when shooting videos or opens heavy files for a long time, the memory card may have exhausted its life cycles of overwriting or initially had low speeds, in which case only replacing the drive with a more productive one will help.
💡
Most of the problems with SD-The cards are solved by their correct formatting directly in the phone, and not on the computer, since the system itself chooses the optimal file structure.
It’s also worth considering that some Xiaomi models have a combined slot, which means you won’t be able to use the two. SIM-In such cases, you have to choose between the second number and the memory extension, or switch to using eSIM technology if it is supported by your operator and the phone model.
