How to switch Xiaomi phone to memory card: full guide

Modern Xiaomi smartphones offer impressive specs, but internal memory often fills up faster than expected. Heavy apps, messenger cache and high-resolution photos instantly eat up the free space, making the system run slower. Owners of devices with limited gigabytes are forced to constantly clean storage or delete unnecessary files.

Fortunately, most models support microSD card installation, which allows you to significantly expand the capabilities of the device. Switching your phone to work with an external media is not a difficult process, but requires understanding the nuances of the Android operating system and the MIUI shell. Proper configuration will help you save all the important data and install more games without losing performance.

In this article, we will discuss how to format your drive properly, transfer media to it, and most importantly, how to try to move applications there. You will learn about the risks of using external media and get answers to frequently asked questions that will help you avoid losing information.

Preparation of a memory card and installation in a slot

Before you start working with files, you need to physically install the media in the device. The SIM card slot in Xiaomi smartphones is usually combined or located next to the main slot. It is important not to damage the contacts when removing the tray using a special clip that comes with the kit.

Make sure your MicroSD card has a sufficient write speed. For modern applications and 4K video recording, it is recommended to use UHS-I or higher speed cards. Slow drives can cause interface friezes and a long gallery opening.

Once the card is installed, the phone will automatically detect the new device, the screen will notify you that a new drive has been discovered, the system will offer two use cases: portable storage or internal storage. For maximum expansion effect, we will consider the second option, but we will start with a basic setting.

⚠️ Note: Formatting a memory card will completely destroy all the data on it. If there are important photos or documents on the media, be sure to copy them to your computer before starting the procedure.

The initial initialization process takes a few minutes, during which time it is not recommended to retrieve the card or restart the phone, interrupting the process can damage the file system and prevent the storage from being used without re-formatting.

Formatting a map as an internal memory

To switch your phone to actively using a memory card to install applications, you need to format it as internal storage. This feature in Android is called Adoptable Storage. SD-card extension of the built-in memory, encrypting data for security.

To start, go to the settings menu. The path may vary slightly depending on the version of MIUI, but it usually looks like this: Settings → About phone → Storage. In some versions of the firmware, the item "Storage" is listed in a separate menu or is located in the "Extended Settings" section.

Find your memory card in the list. Click on it to open the control menu. Select the "Format" option. The system will warn you of data loss. Once confirmed, select the "Internal Storage" mode. The phone will begin the encryption and formatting process, which can take time.

Once the procedure is complete, the system will suggest moving the data. Agree to free up space on the built-in drive. Now your memory card has become part of the system partition, and the file system of the device has changed.

⚠️ Note: Once formatted as internal memory, the card will only work with that particular phone, insert it into another smartphone or computer and read the data without re-formatting it.

Transfer of applications to SD-map

One of the main goals of memory expansion is to be able to install heavy games and programs. However, not all applications support portability. Software developers decide whether to move their product to an external medium. In the MIUI shell, this process has its own peculiarities.

Go to Settings. → Annexes → All applications. Select the program you want from the list. If you can transfer, you'll see the active "Move to" button. SD-map" or "Change" in the app store. If the button is gray or missing, then the developer has forbidden the transfer.

To force transfer of some system applications, users often use debugging mode over USB. This requires connecting to a computer and entering special commands via ADB (Android Debug Bridge). The pm setInstallLocation 2 command makes the system prioritize external storage, but this can lead to unstable work.

It's worth noting that even if you successfully transfer some of the application's data, it's still in internal memory, which are system files and cache, which are necessary for fast operation. It's rare to completely free the built-in disk, but it's possible to save a few gigabytes.

Configure the default photo and video saving setting

The camera is one of the main memory consumers. High-resolution video takes hundreds of megabytes per minute of recording. To keep the phone from overflowing, you better set up the storage of media files on the memory card right away. This is a standard feature available on all versions of the MIUI Camera.

Open the Camera app. In the upper right corner, click on the menu (three bars). Select Settings. Scroll down to Save. Activate the Save on the Save on. SD-map".

Now all new photos and videos will be automatically saved to external storage, not only for the standard camera, but also for most third-party shooting apps like Snapchat or Instagram if they use the camera's system API.

💡

Check card recording speed periodically. If you see a slow card warning when shooting a video in 4K, replace the drive with a faster one (V30 or higher), otherwise the recording may be interrupted.

It is also recommended to check the settings of messengers, in Telegram and WhatsApp, you can manually specify a path to save downloaded files, which will help keep the main array of media content separate from system files.

Transfer of music, documents and downloads

In addition to apps and photos, download files, music and documents take up a significant amount of space. Browsers by default store everything downloaded to internal memory in the Download folder, and you can change this behavior in the browser settings or by moving files after the fact.

Use the built-in File Manager or install a more advanced analog, such as Total Commander or the File Manager. FX File Explorer. Find the Download folder in the internal storage. Select all files, select Copy or Move, and point the path to the back. SD-map.

For music and documents, create a convenient folder structure on an external medium. For example, /Music/Rock, /Docs/Work. Many players and office applications allow you to choose the default folder to search for media files in their settings.

Regular file sorting helps keep things ordery. Don't let hundreds of disparate files lie at the root of the memory card. Structured data speeds up the conductor and the search for the information.

Possible problems and solutions

Sometimes, after switching to a memory card, users encounter errors.The phone can write"SD-The card is corrupted" or "Formatting required. " Often this indicates a file system failure or physical damage to contacts.

If the card is no longer readable, try to remove it, wipe the contacts with a soft eraser, and paste back in. Make sure it snaps to the end. If the problem persists, check the card for errors through your computer using the chkdsk utility in Windows.

Another common problem is slow interfaces, which happens when you have a lot of apps on the map, and the media write speed is slow, so you have to put some of the critical applications back into internal memory.

Also watch the temperature of the device. Active recording of data on an external drive can increase the heat of the processor, as the memory controller works harder, in hot weather or when using a navigator, this can lead to trotting (decreased performance).

⚠️ Warning: Do not remove the memory card "hot" while writing or reading is in progress, this is guaranteed to lead to corruption (damage) of the file table and data loss.
